Waa maxay waxyaabaha sida caadiga ah loo isticmaalo dahaadhka matoorada

Insulating materials are materials that are non-conducting under allowable voltage, but not absolutely non-conducting materials. Under the action of a certain external electric field strength, conduction, polarization, loss, breakdown and other processes will also occur, and long-term use will also occur Ageing. The resistivity of this product is very high, usually in the range of 1010～1022Ω·m. For example, in a motor, the insulating material around the conductor isolates the turns and the grounded stator core to ensure the safe operation of the motor.

Mid ka mid ah: filimada iyo walxaha isku dhafan ee injineernimada korontada

Dhowr polymers molecular sare ayaa laga samayn karaa filimo leh sifooyin iyo adeegsi kala duwan. Astaamaha filimada korantada waa dhumuc dhuuban, jilicsanaan, caabbinta qoyaanka, iyo xoogga korantada iyo farsamada wanaagsan. Filimada korantada ee sida caadiga ah loo isticmaalo waa filimka polyesterka (heerka E), filimka polynaphthyl ester film (heerka F), filimka polyamide aromatic (heerka H), filimka polyimide (heerka C), filimka polytetrafluoroethylene (heerka H)). Inta badan loo isticmaalo sida dahaarka duubista gariiradda matoorka iyo dahaarka dabaysha.

2: Insulating mica iyo alaabteeda

Waxaa jira noocyo badan oo mica dabiiciga ah. Mika sida caadiga ah loo isticmaalo dahaarka korantada ayaa u badan muscovite iyo phlogopite. Muscovite waa mid aan midab lahayn oo hufan. Phlogopite waxay ku dhowdahay dhalaal bir ah ama bir ah, iyo kuwa caadiga ah waa dahab, bunni ama cagaar khafiif ah. Muscovite iyo phlogopite waxay leeyihiin sifooyin koronto iyo kulayl aad u fiican, xasilooni kiimikaad, iyo iska caabin koronto oo wanaagsan. Waxaa lagu diiray karaa xaleef khafiif ah oo dabacsan oo dhumucdiisu tahay 0.01 ~ 0.03 mm. Waa shay muhiim ah oo ceeriin ah oo loogu talagalay soo saarista alaabta dahaarka sare ee tamarta.

3: Badeecooyinka la dahaadhay

Badeecadaha la dahaadhay ee sida caadiga ah loo isticmaalo waxa laga sameeyaa maro dhalada ah (ama mesh) oo lagu rusheeyey xabagta (sida xabagta epoxy, resin silicone ama resin phenolic) ka dibna si kulul loo riixay. Waxaa ka mid ah, guddiga maro muraayadda phenolic waxay leedahay awood farsamo oo gaar ah iyo sifooyinka korantada: laakiin waxay leedahay iska caabin xun oo iska caabin ah iyo caariyaysi guud, taas oo ku habboon samaynta qaybaha dahaarka guud. Epoxy phenolic resin galaas guddiga maro wuxuu leeyahay xoog farsamo sare leh, iska caabin qoyaanka, waxqabadka korantada iyo caariyaysi caariyaysi. Waxay ku habboon tahay matoorada-voltage-ka sare sida qaybo cajiib ah, waxayna ku habboon tahay isticmaalka gobollada kulaylaha qoyan. Boodhka marada muraayadda silikon ee organic waxay leedahay iska caabin kulayl sare leh (darajada H) iyo waxqabadka korantada ee wanaagsan, laakiin xooggeeda makaanikada ayaa ka hooseeya tan guddiga maro dhalada ee epoxy phenolic. Waxay ku habboon tahay qaybaha dahaarka u adkeysiga heerkulka sare waxayna sidoo kale ku habboon tahay meelaha kulaylaha ah ee isku dhafan. Laminates-ka waxaa badanaa loo isticmaalaa sida godad godad ah, gaskets booska, suufka dahaaran iyo looxyada fiilooyinka ee matoorrada yaryar iyo kuwa dhexdhexaadka ah.
