Structure and principle of DC isolation switch

A DC isolating switch is a device for preventing the short circuit between AC and DC of the DC isolating switch. It is connected with an isolating transformer between the power input end of the AC motor power supply switch cabinet and the three-phase AC power input line, and the input line of the three-phase AC power supply is connected with an isolation transformer. It is connected with the primary winding of the isolation transformer, and the secondary winding of the isolation transformer is connected with the power inlet end of the AC motor power supply switch cabinet. Let Sofielec Xiaobian introduce the structure and principle of DC isolation switch one by one for everyone, I hope it will be helpful to everyone.

The DC isolation switch solves the problem that in the control system of the DC isolation switch in the prior art, the insulation strength of the insulator is reduced due to the damage of the insulator between the shell of the AC motor and the deceleration mechanism with DC power and other reasons, or when the AC motor leaks, The resulting AC and DC short-circuit accident. It effectively protects the safe operation of power supply rectifier equipment and prevents major economic losses and personal injury.
Technical characteristics of DC isolation switch switch

The number of poles of the main circuit of the DC isolating switch is three poles, and the operation mode is manual. The design of the switch fully absorbs the advanced technology at home and abroad, and has achieved good results in combination with the actual situation and technological level of our country. It has a reasonable design structure, It has the characteristics of beautiful appearance and reliable work.
