GIS circuit breaker disc spring hydraulic mechanism energy storage pressure control device and circuit breaker

Abstract

The invention provides a GIS circuit breaker disc spring hydraulic mechanism energy storage pressure control device and a circuit breaker, belongs to the field of hydraulic fluid execution mechanisms, and particularly relates to a circuit breaker disc spring hydraulic mechanism. Comprising a power supply, a motor power supply loop and a motor control loop, the motor power supply loop comprises a relay contact connected in series between a motor and the power supply, and the motor control loop comprises at least one of an opening branch, a closing branch and a reclosing branch and a rated branch which are connected in parallel; the rated branch comprises a first switch and a rated limit switch which are connected in series; the opening branch comprises a second switch and an opening limit switch which are connected in series; the closing branch comprises a third switch and a closing limit switch which are connected in series; the reclosing branch comprises a fourth switch and a reclosing limit switch which are connected in series; and one end of a motor control loop formed by connecting the branches in parallel is connected to any end of the power supply, and the other end of the motor control loop is connected to the other end of the power supply after passing through a relay coil corresponding to the relay contact.

Description

technical field [0001] The invention relates to an energy storage pressure control device of a disc spring hydraulic mechanism of a GIS circuit breaker and a circuit breaker, belonging to the field of hydraulic fluid actuators, in particular to a disc spring hydraulic mechanism of a circuit breaker. Background technique [0002] With the continuous expansion of the scale of my country's ultra-high voltage power grid, the number of substations is increasing. In view of the reasons of the environment and the occupied area, the high-voltage switchgear is gradually developing in the direction of miniaturization and light weight. With the development of foreign markets, lightweight products are becoming more and more popular, and production tasks are becoming more and more serious. Therefore, the work efficiency of the factory test needs to be improved while ensuring the accuracy. [0003] At present, the GIS improved circuit breaker produced by the ultra-high voltage manufactur...
