⑴ Kurongeka kwecircuit breakeruye muparadzi wedunhu anofanirwa kufunga nezvekukurumidza kuburitsa chiito kukosha kweyepamusoro-level redunhu breaker, iyo inofanirwa kunge yakakura kupfuura iyo inotariswa inotarisirwa pfupi-yedunhu ikozvino painobuda panopera yepasi-level redunhu breaker.Kana iyo pfupi-yedunhu ikozvino kukosha haina kunyanya kusiyana, mukuru wedunhu anogona kusarudza rwendo unit nekunonoka kwenguva pfupi.
⑵ Kana iyo pfupi-yedunhu ikozvino yakakura kupfuura kana yakaenzana neiyo yekumisikidza kukosha kwekusunungurwa kwepakarepo kwezvino-yekuganhura wedunhu breaker, inotsika mukati memamilliseconds mashoma.Naizvozvo, haina kukodzera kune yakaderera-chikamu chekudzivirira midziyo yekushandisa wedunhu breaker kuti uwane zvakasarudzwa zvekudzivirira zvinodiwa.
(3) Kune dunhu rinoputika nekunonoka kupfupi, kana muganhu wenguva yakatarwa pakunonoka kunonoka, kugadzira kwayo uye kuputsa simba kunoderera.Naizvozvo, mune yakasarudzika yedziviriro wedunhu, funga kusarudza kupfupika kunonoka kugadzira uye kutyora simba redunhu rinotyora kuti riite zvinodiwa.
⑷ Zvinofanirawo kutariswa kuti kunonoka-kunonoka kudzoka hunhu hwepamusoro-level wedunhu breaker uye chiitiko chenguva curve yeyepasi-level redunhu breaker haifanire kupindirana, uye kupfupi-kunonoka hunhu curve uye pakarepo hunhu curve. haifaniri kupindirana.
⑸ Kana dunhu rinotyora uye fuse richishandiswa pamwechete, kurongeka kwemazinga epamusoro neakadzika kunofanirwa kutariswa.Iyo ampere-yechipiri hunhu curve yedunhu inopwanya inofanirwa kufananidzwa neiyo ampere-yechipiri hunhu curve yefuse, kuitira kuti kuve nekudzivirira kusarudzwa mune yenguva pfupi-yedunhu ikozvino.
⑹ Kana iyo yedunhu inotyora ichishandiswa kuchengetedza dunhu rekugovera, muparadzi wedunhu ane kunonoka kunonoka chiito overcurrent kusunungurwa kunofanira kusarudzwa.Kana imwe-phase grounding short circuit inoitika pamagumo emutsara, iyo pfupi yedunhu ikozvino haisi pasi peiyo pakarepo kana kupfupika kunonoka overcurrent of the circuit breaker 1.5 times the set current of the trip unit.
