The electronic mutual inductor gone out.
The technical solution adopted in the utility model is：A kind of electronic mutual inductor of anti-breakdown charged output, including shell
Body, primary winding, iron core, secondary coil, it is characterised in that：The housing upper is equipped with high voltage interface, housing one side lower side
Wall is equipped with ground interface, and high voltage interface divides two-way through the higfh-tension ceramics capacitance of two or more, all the way connection primary winding one end, and one
The secondary coil other end connects ground interface, and secondary coil corresponds to primary winding and is wire-wrapped on iron core, secondary coil one end ground connection, and two
Two end of secondary coil is connected on the aviation socket in the terminal box on the lower sides of housing one side；Another way connects high-voltage bleeder, high
Divider one end ground connection is pressed, two end of high-voltage bleeder is connected on the test splice in the terminal box on the lower sides of housing one side；Shell
Filling epoxy resin in body and terminal box.
The high-voltage bleeder is RC divider or resitstance voltage divider.
The hull outside covers silica gel sheath.
This mutual inductor is used as high_voltage isolation equipment, it is necessary to ensure its on high-tension side voltage endurance capability, two or more higfh-tension ceramicses
Capacitance series connection improves the security performance of mutual inductor, even if wherein a capacitance is breakdown, high pressure will not pass to low-pressure end, ensures
The safety of secondary device and operating personnel.Secondary coil exports, and original edge voltage substantially reduces, reduces the primary side number of turn, there is item
Part increases winding wire diameter, greatly reduces the copper loss of mutual inductor, improves the transfer efficiency of mutual inductor.The electronic mutual inductor can
