LOTO- Magetsi enguva pfupi

Kugadzika kwe "muchina mumwe, bhokisi rimwe, switch imwe, kudonha kumwe" hakumanikidzwi kuti simba rishandiswe kwenguva pfupi.

"Bhokisi rimwe, muchina mumwe, switch imwe, leak imwe" zvinoreva kutsanangurwa kwemagetsi echinguvana, zvichireva kuti michina yega yega yemuchina inofanira kunge iine bhokisi rekuchinja rakasiyana, bhokisi rekuchinja rinofanira kuiswa svumbunuro yebanga (switch yekuzviparadzanisa) uye chidziviriro chekubuda kwemvura, switch inogona kupomba michina imwe chete yemuchina, switch inogona kusashanda zvakanaka uye tsaona. Sezvakaita mutsaona iyi, Gong nevamwe vanoshanda vachitevedzera "zvinodiwa zvekuchengetedza magetsi zvechinguvana panzvimbo yekuvaka", bhokisi rekuparadzira nebhokisi rekuchinja, zvichienderana ne "bhokisi rimwe chete muchina mumwe, switch imwe, leak imwe", ichashongedza michina yevashandi nemidziyo yemagetsi zvakaparadzaniswa, tsaona inogonawo kudzivirirwa.

Bhokisi renguva pfupi rekugovera simba uye bhokisi rekuchinja

Zvinoenderana neChinyorwa 8.1 cheTechnical Specification yeTemporary Electricity Safety on Construction Site, magadzirirwo emabhokisi ekugovera neswitch box anofanira kusangana nezvinodiwa zvinotevera: 1. Sisitimu yekugovera yezvikamu zvitatu inotorwa. Iyo inonzi three-level distribution ndiyo total distribution, distribution, switch box three-level, three-level distribution, three-level, three-level, three-level protection, to a machine, a gate, a leak, a box, a lock.

Sistimu yekudzivirira yeTN-S zero. Sisitimu yekudzivirira yeTN-S zero connection ine 32 zero mutsetse unoshanda uye sisitimu yekudzivirira yekudzivirira yekubatana yakagadzikwa zvakasiyana. 3. Dziviriro yekudzivirira yekubuda kwemvura. Dziviriro yekubuda kwemvura kunoreva kuti sisitimu yemagetsi inofanira kunge yakashongedzwa nedziviriro yekudzivirira kubuda kwemvura mubhokisi guru rekugovera nebhokisi rekuchinja. Nguva yekubuda kwemvura yakarongwa uye nguva yekubuda kwemvura yakarongwa yedziviriro yekubuda kwemvura mubhokisi guru rekugovera nebhokisi rekuchinja inofanira kurongeka zvine mwero kuti igadzire dziviriro yakarongwa uye yechikamu.
