【文章內(nèi)容簡(jiǎn)介】 s a secondary voltage directly proportional to its primary voltage。the difference between a potential transformer and a power transformer is that the potential transformer is designed to handle only a very small second type of special transformer is a device designed to provide a secondary smaller than but directly proportional to its primary device is called a current transformer. Cirtcuit Breakers A circuit breaker is mechanical switching device capable of making,and breaking currents under normal circuit conditions and also for a specified time ,and mediujm in which circuit interruption is performed may be designated by a suitable prefix, for example,airblastcircuit breaker,oil circuit circuit breakers currently in use can be dlassified into the following categories according to the arcquenching principles:air swetches oel ciryit breakers,minmumoil circuit breakers,airblast circuit breakers,the mageic air circuit breakers,minimumoilcircuit breakers,aerblast circuit breakers,the by voltage,insulation levelcurrent,interrupting capabilities,transient recovery coltage,interrupting tiome,and trip nameplate on a circuit breaker usually indicates:１ .The maximum steadystate current it can carry, 2. The maximum interrupting current,3. The maximum line voltage, interrupting time in cycles, The interrupting time in may last form 3 to 8 cycles on
