Abstract

The present invention relates to an all-optical current transformer with an integrated isolation circuit breaker, which includes a primary side sensitive unit, fittings, a suspension insulator and a T-shaped flange. Fixed at one end of the suspension insulator, the outer side of the arm perpendicular to the central axis of the T-shaped flange is fixedly connected with the flange of the isolating circuit breaker, and the arm where the central axis of the T-shaped flange is located is connected to the high-voltage busbar The back of the ring structure of the fitting is fixedly arranged on the inner side of the arm perpendicular to the central axis of the T-shaped flange. The all-fiber-optic current transformer integrated with the isolation circuit breaker involved in the present invention can realize the integration of the isolation circuit-breaker and the all-fiber-optic current transformer, and is suitable for the integrated and intelligent requirements of a new generation of intelligent substations.

Description

technical field [0001] The invention relates to the technical field of current transformers, in particular to an all-optical fiber current transformer integrated with an isolation circuit breaker. Background technique [0002] The current sensor / transformer is an important device for relay protection and electric energy measurement in the power system. It is used to measure the current in transmission and send the measured current to the measuring instrument and relay protection device for measurement and protection. The device provides a current signal. The long-term stability, reliability and safety of current transformers are closely related to the safe and stable operation of power systems. With the development of power systems towards large capacity, ultra-high voltage and ultra-high voltage, the requirements for miniaturization, intelligence and high reliability of power equipment are getting higher and higher. Due to the increase of the system voltage, the tradition...
