A sf with water removal function 6 High voltage circuit breaker arc extinguishing chamber

Abstract

A SF with water removal function 6 High-voltage circuit breaker arc extinguishing chamber, which belongs to high-voltage SF 6 circuit breaker technical field. Including the arc extinguishing chamber shell (13), the static contact mechanism (5) and the inner base (17) are arranged in the arc extinguishing chamber shell (13), and the middle part of the inner cavity of the arc extinguishing chamber shell (13) is set There is a moving contact mechanism, which is characterized in that: the top and bottom of the inner cavity of the arc extinguishing chamber (13) are respectively provided with an arc extinguishing chamber adsorption box (1) and a bottom heating wire (19); the insulating pull rod ( 10) is a hollow structure, an insulating tie rod closure (12) is arranged in the inner cavity of the insulating tie rod (10), and a tie rod adsorption bucket (14) is also arranged at the bottom of the insulating tie rod closure (12). In this SF with water removal function 6 In the high-voltage circuit breaker arc extinguishing chamber, the removal of water vapor in the arc extinguishing chamber is realized, and by setting the insulating pull rod closure and the pull rod adsorption barrel in the insulating pull rod, the water vapor generated in the high-temperature gas during arc extinguishing can be isolated and adsorbed.

Description

technical field [0001] A SF with water removal function 6 High-voltage circuit breaker arc extinguishing chamber, which belongs to high-voltage SF 6 Circuit breaker technology field. Background technique [0002] High-voltage circuit breakers are the most complex and important electrical appliances in high-voltage equipment. They can realize the dual functions of control and protection, and are widely used in power plants, substations, switching stations and power lines in power systems. High pressure SF 6 The circuit breaker is made with SF 6 Gas as an arc extinguishing and insulating medium for circuit breakers. Thanks to SF 6 The gas has excellent arc extinguishing and insulation properties, as well as high fracture voltage, strong breaking capacity, allowing many times of continuous breaking short-circuit current, suitable for frequent operation, breaking capacitive current without re-ignition or re-ignition, breaking Inductive current can have many advantages such...

Problems solved by technology

High-voltage circuit breakers are relatively important key components in the power grid. Dehumidification and delayed start-up time will inevitably cause certain economic losses, but the normal operation of high-voltage circuit breakers cannot be guaranteed without regular dehumidification.
