Ma'ana ta Circuit Breaker Maintenance

Circuit breaker maintenance yana nufin kawo wani, karfin, da kuma tattaunawa da tattara mai karfi a kanidanci don inganta hankali da shirya.

Bulk Oil Circuit Breaker

Don bulk oil circuit breaker, zan iya tattauna tsayon da mutu. Idan tsayon ya fi yawan goma, za a cika tsayon da kuma sauka suka. Idan tsayon ya fi yawan goma, za a fada tsayon da kuma arcing ring da sabon set. Zan iya faɗa da kima tsayon maimakon lokaci na ƙarfi.

Kuma, za a tattauna extinguishing chamber. Za a cika shi daga unit, za a rufe shi da insulating oil, da kuma za a ci shi ƙarshe. Za a fada duk wata da ya fi yawan goma ko daɗi.

Sannan, za a soja da kuma ƙare mechanism ta circuit breaker. Za a cika rust da non-fluffy cotton cloths da kuma ƙare mechanism, ciki har da gear wheel, da high-grade grease. Tabbacin ƙarin, za a ƙare friction clutch. Don minimum oil circuit breaker (MOCB), za a soja insulator da kuma za a cika carbon deposits da Trichloroethylene ko Acetone. Tabbas ƙarin, za a yi amfani da manual na manufacturer don tushen bayani masu ma'ana.

Za a tattauna locking pins of the tie rods da foundation bolts da electrical terminal connections a power circuit ta circuit breaker kowace ƙarfe. Za a ƙarfa shi daidai ba a cika oxide coating ba.

Idan auxiliary switch ya haɗa, za a tattauna NO NC contacts a OFF da ON condition ta breaker kowace ƙarfe, da kuma auxiliary switch’s contacts zan iya soja da hard brushes.

Spring charging motor da mechanism zan iya soja da kuma bearing da take ƙare kowace ƙarfe.

Minimum Oil Circuit Breaker (MOCB) Maintenance

A nan MOCB, za a tattauna leakage da level ta oil kowace wata. Idan leakage ta oil an samu, za a ci gaba, da kuma idan level ta oil ya ƙoƙari, za a ƙara oil zuwa level ta da shi.

Za a yi tattauna visual ta circuit breaker, operating mechanism, painting quality, da mechanism kiosk door gasket kowace ƙarfe. Idan ana samu lafiya, za a yi aiki daidai.

Oil dash pot a operating mechanism zan iya tattauna leakage kowace ƙarfe, idan leakage an samu, za a fada defective da damaged O – rings. Ana bukata a yi prescribed duty cycle of operation of the breaker including reclosing kowace shekara.

Air Blast Circuit Breaker Maintenance

Don air blast circuit breaker, akwai wasu abubuwa masu muhimmanci don tattauna wajen kawo irin general instruction for maintenance of operating mechanism. Amma, don operating mechanisms da wasu abubuwan da suke, tushen tattara da schedules suna ɗauke don duk oil circuit breaker, air circuit breaker, SF6 circuit breaker, da vacuum circuit breaker.

A air circuit breaker, za a tattauna leakage ta air inda an buƙata. Idan leakage an samu, za a ci gaba.

Grading capacitors zan iya tattauna leakage ta oil kowace wata. Idan leakage an samu, za a ci gaba. Kowace shekara, za a tattauna dew point ta operating air a outlet ta air dryer da Dew Point Meter ko Hygro Meters.

SF6 and Vacuum Circuit Breaker

Saboda haka, don operating mechanisms da wasu abubuwan da suke, tushen tattara da schedules suna ɗauke don duk oil circuit breaker, air circuit breaker, SF6 circuit breaker, da vacuum circuit breaker.

Kafin ake ƙara, a SF6 CB, akwai wasu abubuwa masu muhimmanci. SF6 circuit breaker zan iya tattauna leakage ta SF6 gas, idan unwanted SF6 low gas pressure alarm an samu. Wannan yana ƙarfin da gas leakage detector. Idan circuit breaker an haɗa gradient capacitors, za a tattauna leakage ta oil kowace wata. Idan leakage an samu, za a ci gaba. Dew point ta SF6 zan iya tattauna kowace 3 to 4 years interval da Dew Point Meter ko Hygro Meters.
