ZKTD型号陶瓷真空开关管TYPE ZKTD CERAMIC VACUUM INTERRUPTORS

 真空开关管采用陶瓷外设,真空介质,具有分断能力强、电弧不外露、安全可靠等优点,是煤炭、化工、电力、冶金等部门理想的控制电器用开关管。

  该型号产品配以合适的操作机构,可装配成高、中、低压交流断路器、交流接触器,作高、中、低压配电控制装置,供远距离接通与分断电动机、变压器、电容器组等交流电路之用,特别适宜组成隔爆型磁力起动器。

  With ceramic envelope and vacuum dielectric , the vacuum interrupter offers a number of advantages , such as high interrupting capability , inside electric arc , safe and reliable ,etc . It is the ideal interrupter used for controlling electrical equipment in the fields of the coalmine , chemical, electric power, metallurglcal industry and so on .

  Being fittde with appropriate operating mechanism ,the interrupter can be constructed to the HV/MV/LV AC circuit breaker or AC contactor used for the controlling devicos of the power distribution, the remote turning on and switching off motors , in the AC circuits such as transformer and capacitor banks . Especially , it is suitable to use as the isolate-explosion type magnetic starter.
