TK series capacitor fast switching switch is suitable for capacitor fast switching switch used for power reactive power compensation of < 0.69kv system. It adopts silicon controlled rectifier module as switching device, pulse transformer trigger, advanced high-speed single-chip microcomputer measurement algorithm to ensure that the current is disconnected at zero crossing point, no switching inrush current is generated, and the response time is less than 20ms, It can effectively compensate the impact load, built-in temperature protector and temperature control algorithm, so that the fan can be used reasonably and safely; the application of over-current protection can prevent the over-current risk caused by system resonance and other reasons.
