breaker ciorcad bhfolús

"Vacuum circuit breaker" is named because both the arc extinguishing medium and the insulating medium of the contact gap after arc extinguishing are high vacuum; it has the advantages of small size, light weight, suitable for frequent operation, and no need for maintenance for arc extinguishing. The application in the power grid is more popular. The vacuum circuit breaker is an indoor power distribution device in a 3-10kV, 50Hz three-phase AC system. It can be used for protection and control of electrical equipment in industrial and mining enterprises, power plants and substations. In the places of maintenance and frequent operation, the circuit breaker can be configured in the middle cabinet, double-layer cabinet and fixed cabinet to control and protect high-voltage electrical equipment.

prionsabal oibre

Nuair a bhíonn an scoradán ciorcad bhfolús sa suíomh dúnta, is é an t-inslitheoir tacaíochta a iompraíonn a insliú talún. Chomh luath agus a tharlaíonn locht buan talún sa líne atá ceangailte leis an bhfolús briseadh ciorcad, tar éis an scoradáin chiorcaid a thurais, níl an pointe locht talún glanta, agus tá busbar leictreach ann. Ní mór an insliú talún a iompróidh freisin ag an bhearna folúis an briste breaker; nuair a chuirtear isteach ar lochtanna éagsúla, ní mór don bhearna inslithe i bhfolús idir péire teagmhálacha an bhriste gníomh na voltas aisghabhála éagsúla a sheasamh gan miondealú. Mar sin, tá airíonna inslithe na bearna folúis mar phríomhábhar taighde chun voltas briste an tseomra múchta stua a fheabhsú agus an scoradán ciorcaid fholús briste aonair a dhéanamh go leibhéal ardvoltais.
