Combined Current ? Voltage Transformer with Dead-Break Interface like Bushing or Bushing Well onto Primary Terminals

摘要

The present design is that as, more particularly, to input and output terminals located at the upper end of the instrument transformer current transformer for made of a conventional one-piece and built-up on the instrument transformer current transformer for the structure of the input and output terminals connected to a cable connection member exposed to the outside, here Dongda (Bus bar) to connect to and to to the wires insufficient insulation to improve the problem of the electric shock, the input-output terminal is formed in a bushing well (Busingwell) shape or a bushing (Busing) the shape of the conical cylindrical epoxy 'side top surface and one "" the top surface of a resin, "" an aspect, "" one by being formed either one of the sides and the other side "is selected, so tightening the cable connecting the direct, addition not at all exposed to the output terminal eliminating the need for sub-installation mechanism, such as fabrics protection device, since the high-voltage charging, including input and output terminals is electrically isolated between the high voltage live part and ground, or between phases Standing apart insulated to minimize the distance it relates to a current transformer Instrument transformers for the economy and safety of high power demand is reduced installation space.
