AL310  Self pressure-lifting precise voltage mutual inductor

Implementation of standards.

ZBY096-82

Self pressure-lifting precise voltage mutual inductor is rolled with cold rolling silicon steel slice which has high magnetic density and high magnetic permeability and then experiences the heat treatment. There are separate voltage booster and mutual inductor in the inner part. Voltage booster adopts magnetic screen. High-pressure output of the voltage booster is parallel connected with standard mutual inductor to output as lifting pressure via high pressure terminal post to provide high voltage for measured voltage mutual inductor. High and low voltage of the mutual inductor all adopts insulated structure. High voltage winding adopts special material and no-oil insulated effective technique abolishing the disadvantage of the oil-inrush voltage booster.
