Quando o foco é didático a montagem de um painel de comando muitas vezes é ensinado começando do diagrama de comandos elétricos, mas na prática é assim que deve ser feito?

COEL – 300×250

Neste artigo quero te mostrar como é feita a montagem de um painel de comando elétrico e porque que na verdade o primeiro passo deve ser o diagrama de potência.

Leia este artigo para entender como você irá realizar a montagem no seu dia a dia quando estiver atuando na profissão de eletricista montador.

O que é um painel de comando elétrico?

painel-de-comando

Um painel de comando é na verdade um conjunto de componentes elétricos com a finalidade de acionar uma determinada máquina elétrica e que normalmente compõe um sistema mais complexo, como um torno mecânico por exemplo.

Em um painel de comando você encontrará normalmente dois conjuntos de interligações de cabos elétricos, os de comandos e os de potência.

Podemos dizer que os cabos de comandos são os responsáveis (junto com os componentes) por determinar a lógica de funcionamento da máquina elétrica a ser acionada.

Os cabos que compõe o circuito de potência são responsáveis, junto aos componentes, por conduzir as fases de alimentação da máquina que será controlada/acionada.

Por onde começar a montagem de um painel de comando?

painel-de-comando

Como comentei no início, na escola, estrategicamente nós professores iniciamos a ensinar a montagem de um painel de comando pelo circuito de comandos elétricos. Isso porque se torna fácil a visualização do circuito “impresso” nos componentes a partir da inclusão dos cabos.

Mas na prática, a montagem é iniciada pelo circuito de potência e isso tem uma explicação lógica.

Pense comigo, os cabos que representam o circuito de potência na grande maioria dos casos possuem maiores seções transversais (bitola).

Iniciar a montagem por eles é uma forma de garantir a melhor performance na montagem, já que, por ser mais robusto, seria totalmente inviável finalizar a montagem com estes condutores.

  1. Tak som sa konečne dopracovala aj tu a jednou rukou píšem koment a druhou si držím spodnú časÅ¥ sánky. Krásne – ako povedala wicked lady, vidno že čítaÅ¡ niečo úplne iné, než my ostatní smrteľníci a samozrejme má potom aj tvoja poviedka patričnú úroveň 🙂 Dúfam, že vyhráš, určite si to zaslúžiÅ¡ ty. Inak idem sa ti popozeraÅ¥ po blogu a počítaÅ¥ si niečo iné, mám pocit že sa tu esteticky vyžijem.

  2. Most of what you point out is astonishingly accurate and that makes me ponder why I hadn’t looked at this in this light before. This article truly did turn the light on for me personally as far as this particular subject matter goes. Nevertheless there is one point I am not necessarily too comfy with and whilst I attempt to reconcile that with the core idea of your issue, permit me see just what the rest of your readers have to say.Well done.

  3. Some tips i have always told people is that when evaluating a good online electronics retail store, there are a few elements that you have to factor in. First and foremost, you should make sure to find a reputable as well as reliable retail store that has received great opinions and classification from other individuals and business world leaders. This will make certain you are dealing with a well-known store providing you with good services and assistance to it’s patrons. Many thanks for sharing your thinking on this weblog.

  5. Paulo, um cidadão que ainda tem esperança! Português de têmpera. Eu já quase que a perdi. Trinta e tal anos com tantos erros cometidos na área da política e da ecónomia dá que pensar. As pessoas “bem orientadas” tentam aprender com os erros, mas os políticos portugueses (não todos) andam ainda à procura de rumo … qual não sei!

Simplemente un maestro.. es genial la historia que hay detras de este señor.. la forma en que se dio a conocer, la forma en que toca los instrumentos, la forma en que hicieron las producciones… que envidia Diana!Yo tengo las ultimas 2 (son 3) producciones y no me canso de escuchar a este señor… demasiado rico escuchar esos calysos cuando uno se quiere relajar un poco…. y el señor todo un icono sin duda.Saludos

  10. Men should hope that women win the gender neutral battle. Imagine the fortunes husbands would save when they no longer have to subsidize their wives' jewelry, makeup, hair products, clothing and accessories. Unfairly, when women no longer wear that camouflage, and when every women is dressed in a flannel shirt and Levi's – the natural beauties stand out even more! Fine symmetrical features, long eyelashes, smooth hairless complexion – the old and the ugly still won't stand a chance.

  13. Dear Family, I am saddened beyond words of Edna’s passing; however, she and Vernon are reunited a final time. God truly blessed them here on earth, and He too has blessed them in heaven. Edna was a very dear, dear friend and we shared many things through the number of years we’ve known one another. I’ve missed her so much and will remember each of you a little more in my prayers each and every day. MUCH LOVE TO ALL,-Becky

  14. Bom dia, eu bati o lado direito do queixo não muito forte, no momento doeu um tempo e passou e depois só doia levemente o local, não saiu sangue nem apareceu lesão externa, não esta encomodando, porém tenho medo de que isso afete os meus dentes de alguma maneira posteriormente ou que posso ficar com o queixo caído, no momento não há nenhum problema, há esta possíbilidade?

  15. Très drôle la notice d’utilisation façon contrat de licence d’un logiciel, que personne ne lit. Mais bon, actuellement, qui lit les notices des médicaments puisqu’ils sont sensés être prescrits par des gens qui savent ce qu’ils font ? Et puis les médecins devraient se réjouir, avec toutes les intoxications médicamenteuses que l’auto-médication va provoquer, ils vont avoir plein de boulot.

  16. man sollte vllt ganz nebenbei noch erwähnen, wenn man schon mit dem patch tool arbeitet, sollte man darauf achten, wenn man eine stelle einkreist und an eine andere stelle verschiebt das man auch hautregionen erwischt, die ungefähr den selben hautton haben ^^ ansonsten gibt das unschöne flecken ich dachte wenn man schon ein tutorial für anfänger macht, werden solche “unwichtigen kleinigkeiten” auch erwähnt

  17. It is possible to be too obsessed with food and exercise, as with anything else, but I don’t think that you’re there yet. Good luck on your weight loss! From experience, recording what you eat and do really helps a lot. I have actually never heard of FitBug or FitBit, so I might just try them out sometime!

  20. Paul Theroux’s book, Dark Star Safari and Keith Richburg’s, A black man confronts Africa book are equally depressing but both are well worth reading.BTW the EU wants Europe to accept 45-50 million African immigrants over the next twenty five years.Richard – London

  23. Die Politiker machen auch nur ihren Job. Sie müssen sich so entscheiden, dass es für alle Beteiligten recht ist. Und solche Entscheidungen brauchen eben Zeit. Es gibt so viele Probleme in der heutigen Zeit. Die Politiker müssen viele Probleme lösen. Sie sind auch nur Menschen und können keine Wunder wirken.

Il avait été trahi par son ami Octave.Les moeurs politiques de l’époque étaient moins tendres et plus tranchantes que celles d’aujourd’hui…

  25. mi sembra proprio che tu non riesca a posizionarti tra la visione maschilista e quella femminista della maternita'. Vedo nei tuoi posts un continuo ondeggiare tra questi due estremi. Cosa michia ti aspetti se assumi come tata una così gnocca? Chi l'ha scritto questo? Uno di quegli uomini mammoni che che non si sanno prendere le responsabilita' di cui parlavamo? Certamente, un commento cosi' sarebbe inaccettabile sui media americani!

  26. Excellent article Mr Greenfield. Keep up the good work. I enjoyed the responses from the posters. Very informative. I believe the Left and Islam are definitely two sides of the same coin. No question. The question for me is will our kind unite in time and take the action required to save our civilisation and prevail, or are we leaving it too late?

  30. Fico muito contente pelos russos. Que seja uma oportunidade para melhorar a oferta hoteleira e acessos em Moscovo e São Petersburgo e de desenvolver algumas cidades de média dimensão (para a realidade russa). Que mais algumas Sochi apareçam.

  31. something is legal, then it is. If Congress passes a law stating X, then X is legal until the courts overturn it. At which point Congress rewrites it, or impeaches the judges.Rule of law is assumed, but the laws are written by (again, we assume here) elected officials representing the masses of voters. That was my underlying assumption.

Jay Lansdaal / Now this version of the deck looks awesome!No more captains that were both clunky on the mana, as well as being an underwhelming blood artist most of the times, the mana is better, Porcelain Legionnaire is a good man, no infinite 3 drops, plus your SB looks really useful too.Great job, must've taken quite some testing!

  34. Pretty neat and useful tips for optimising the space in the laundry room thanks for sharing them. I might even try some of them in my house because my girlfriend is constantly on my back to put some shelves in the laundry room to free up some space for her to move around. Keep up the good work

  35. I don't think so, Average Joe. As with most dating sites, I'm pretty sure the men outnumber the women on Jdate. At least that was the case when I was on it. I don't know the percentages of Jewish men marrying out of the faith vs. Jewish women. If you have a link on that feel free to share.

  37. mij is verteld dat de gemeente die postertjes waarop de esdoorn staat, heeft gedrukt op voorwaarde dat er een T op zou komen. Dat de T zo prominent in beeld zou worden gebracht, op een manier zelfs dat in visueel opzicht het totaal beeld van de poster wordt afgebroken, was niet afgesproken.Intussen heeft de gemeente op handige wijze de indruk weten te wekken dat het commerci

  38. 24 billion later in Texas and no benefit. Wind proponents keep saying wait until the system is expanded, there is always wind somewhere. Treating the wind grid as some text book fourier analysis. In the real world it is a bust. Everything is on the chopping block in Texas….no money for decommisioning

  39.  ( 2012.02.15 17:24 ) : Thanks for some other excellent post. Where else might just anyone get that type of info in such an ideal indicates of writing? I’ve a presentation next week, and I’m at the search for such information.

  41. Big *OOOOO AHHHHH* for that faux fur coat. (GAWDDD I love it) I came across one last week and wanted it so badly.. but the Hubs made me try it on and I was sort of swimming in it. (BOOO)Hopefully I find one that fits at some point in the near future. lolYour whole outfit is great (Nice boots)too!

  42. je rejoinds icepoon, Nolan avait très peu de moyens quand il a fait Following, à mon avis la différence entre le Blu-ray et le DVD ne sera pas si flagrante que ça.En tout cas le film est une très bonne première réalisation de la part du grand Christopher Nolan, on sent que ça a été un film réalisé par lui, on reconnaît sa patte, ses thèmes de prédilections.

  44. I agree with everyones comments. I have a few close friends (though none not close) who know to nudge me when I seem to be faltering. Last year I purchased a domain name, which I now own for 5 years. This month I found a host site & am working towards setting up my own website, with all the bells & whistles that go with it.So if you hear a high-pitched sound & no one is around, it is only me – venting as I figure out the next step.

  45. Stessa cosa per me: tutti i link portano alla stessa destinazione, così come tutte le strade portano a Roma.Succede sia con Firefox che con Safari, secondo me è una ritorsione di Blogspot all'annuncio di Paolo di volersene andare, l'ordine supremo degli amministratori di sistema fa sentire il peso oscuro del proprio potere 🙂

  46. Tell me where to deliver the food, table and flowers! May we all have the attitude to give and share the abundance that we have with others and not just ignore needs that are placed right before us. Let us not be guilty “If a brother or sister be naked, and destitute of daily food, And one of you say unto them, Depart in peace, be ye warmed and filled; notwithstanding ye give them not those things which are needful to the body; what doth it profit? Even so faith, if it hath not works, is dead, being alone.” (James 2:15-17)

Et aucun regret. Vraiment fabuleux ! Violent mais si doux, Lourd mais frais, dramatique mais avec tellement d’espoir à la fois !Par contre, c’est pas un film hyper joyeux. Je préconise donc une soirée entre amis à suivre.(Je suis tombée amoureuse de Foenkinos avec la Délicatesse et pas trop déçue non plus du film.
