Voltage stabilizer Different requirements analysis

Different operating system of exchanges and contacts made entirely different requirements, focusing face when considering the choice of a different Switchgear & Substation‍ nature. When the "voltage stabilizer" and "short-time working" equipment selection is subject to fewer constraints contact, just consider the contactor rated operating current can be greater than the actual, proper equipment is important when you put a little margin. The ability to "stop work" system should first consider equipment selection contacts Dust-creepage prevent overheating, compact structure should not use contactor (circuit breaker for use when necessary). To prevent overheating, the contactor should enlarge the Power Supply‍ capacity of more than 20% of large chemical plant electrical equipment mostly this is the case. We must first consider the mechanical life of electrical contacts and operating mechanism of life belonging to heavy duty and special heavy task of "intermittent periodic duty" equipment selection contactors should be used CJ12 series (especially suitable for winding motor), CJ20 series or series of vacuum contactors, due to derating can greatly improve the electrical contactor life can easily be selected as the starting mcb circuit breaker‍ current of the motor contactor rated current to improve the safety and reliability of production unit.
