Abstract

The invention discloses an external integrated type all fiber optical current transformer for an isolated-type circuit breaker. The current transformer comprises fan-shaped mounting plates, a connecting terminal, a hardware fitting outer cover, a hardware fitting base plate, suspension-type insulators, a welding plate, an adjusting plate, a sensing ring, an insulation pad, an insulation sheet, a seal ring, a base mounting plate, a corrugated pipe, an electrical unit, and the like. The external all fiber optical current transformer is directly mounted on the outer side of the isolated-type circuit breaker, and the all fiber optical current transformer is wholly hung on the outer side of a flange of the isolated-type circuit breaker through the fan-shaped mounting plates, and the lower end of the all fiber optical current transformer is fixed through the base mounting plate. The current transformer disclosed by the invention has high independence, high flexibility, wide measuring dynamic range, and high frequency responsivity so as to fill up the blank of the industry in the isolated-type circuit breaker application field.

Description

Technical field [0001] The invention relates to an external integrated all-optical current transformer of an isolation circuit breaker, which belongs to the technical field of electrical measurement. Background technique [0002] Current transformer is one of the key equipment in power transmission and transformation. It plays a role in accurately and quickly measuring electrical parameters in the system, and plays a vital role in the safe and reliable operation of power transmission and transformation systems and power equipment. With the continuous improvement of science and technology and industrial level, isolating circuit breakers have replaced isolating switches and circuit breakers as the development direction. Integrating the isolation circuit breaker and the electronic transformer into an integrated manufacturing can greatly save the land used in the substation, and the economic benefits are considerable. Statistics show that the integration of the optical transformer an...
