Problems solved by technology
[0004] The disadvantages of the prior art are: 1. In the prior art, the opening / holding of the circuit breaker is completely handed over to the opening spring. Due to the closing force of the contacts in the vacuum interrupter, once the opening spring is compressed due to long-term compression Attenuation or plastic deformation of the opening spring, unable to provide the set opening force, thus affecting the opening distance of the contacts; 2. In order to ensure the opening distance of the circuit breaker, it is necessary to increase the final opening distance of the opening spring The force value will increase the wire diameter and height of the spring, which will bring a lot of force when we close the switch, increase the difficulty of the operating mechanism, and bring safety hazards

The invention discloses a brake breaking device for a vacuum arc-extinguishing chamber. The brake breaking device comprises holders, clamping devices, holding sliding sleeves and a running end copper stock. Each holding sliding sleeve is arranged on the outer circumference of the front end of the running end copper stock. The outer diameter of each holding sliding sleeve firstly gradually becomes large and then gradually becomes small. The outer sides of the holding sliding sleeves are sleeved with the holders. A circular groove is formed in the inner wall of each holder. The clamping devices are arranged in the circular grooves, and the holding sliding sleeves are clamped by the inner walls of the clamping devices. By the adoption of the brake breaking device, the distance between vacuum envelopes can be controlled, and the vacuum arc-extinguishing chamber can be made to meet the electrical performance requirements.
Description
technical field [0001] The invention relates to a component of a vacuum interrupter, in particular to an opening device for a vacuum interrupter which can control the opening distance of vacuum bubbles and make the vacuum interrupter meet the electrical performance requirements. Background technique [0002] Vacuum interrupter: also known as vacuum switching tube, is the core component of medium and high voltage power switches. Its main function is to quickly extinguish the arc and suppress the current after the medium and high voltage circuits are cut off through the excellent insulation of the vacuum inside the tube, so as to avoid accidents and Accidents happen. [0003] The opening of the circuit breaker of the existing vacuum interrupter is only realized by the opening spring, and the force stored in the spring directly pushes the moving end contact of the vacuum interrupter to achieve the purpose of breaking the current. [0004] The disadvantages of the prior art are...
