Conas teirmeasóirí PTC a úsáid mar chosaint reathaForThe2920 Dromchla Mount PTC Fuse Athshocraithe
Ceann de na hairíonna atá ag teirmeastair PTC nuair a shreabhann sruth atá ró-mhór, gineann siad teas iontu féin agus éiríonn siad an-fhriotaitheach. Leis an maoin seo, úsáidtear iad mar ghléasanna cosanta forshrutha. Déanann an t-alt seo cur síos ar iarratais chun na gcríoch seo a leanas. «Le haghaidh teorannú srutha inrush» «Le haghaidh cosanta forshrutha» «Le haghaidh teileachumarsáide»
Buntáistí teirmeastair PTC
Is friotóirí teocht-spleách iad teirmeasóirí PTC atá bunaithe ar chriadóireacht leathsheoltóra speisialta a bhfuil comhéifeacht teocht dearfach ard acu (PTC). Taispeánann siad luachanna friotaíochta réasúnta íseal ag teocht an tseomra. Nuair a shreabhann sruth trí PTC ardaíonn an teas a ghintear teocht an PTC. Chomh luath agus a sháraítear teocht áirithe (teocht Curie), ardaíonn friotaíocht PTC go suntasach. Is féidir an éifeacht seo a úsáid chun ciorcaid nó gairis a chosaint ar fhorshruthanna. Sa chás seo, tugann an forshrutha an PTC go teocht ard agus ansin cuireann an fhriotaíocht ard a eascraíonn as teorainn leis an bhforshuí. Nuair a chuirtear deireadh leis an gcúis le mífheidhmiú, fillfidh an PTC air agus gníomhóidh sé arís mar fhiús in-athshocraithe. Leis an maoin seo, úsáidtear teirmeastair ríomhaire mar ghléasanna cosanta fánacha. Déanann na feidhmchláir eiseamláireacha seo a leanas cur síos ar an gcaoi ar féidir teirmeastair PTC a úsáid le haghaidh cosanta forshrutha.
