Abstract

Provided is a novel vacuum interrupter structure. The novel vacuum interrupter structure mainly comprises a vacuum tube and a double-repulsion disc, the double-repulsion disc is located at the lower end part of the vacuum tube, a moving contact of the vacuum tube and a repulsion coil panel of the double-repulsion disc are connected through a conducting rod, the moving contact and the repulsion coil panel simultaneously move under stress, and the novel vacuum interrupter with a auto-breaking function is formed. When a system has a short circuit fault, field current is charged to the repulsion coil panel through the conducting rod by short circuit current, a magnetic field is generated, a repulsion copper disc forms induction eddy current under the effect of the magnetic field, the direction of the induction eddy current is opposite to the direction of the field current, a huge electromagnetic repulsion is generated between the repulsion copper disc and the repulsion coil panel, a repulsion coil drives the conducting rod to pull the moving contact for rapid switch-off, and the goal of rapid line switching is achieved. According to the vacuum interrupter, the auto-breaking function is provided, the immediacy is high, the motion speed is high, and the overall structure is more compact.

Description

technical field [0001] The invention relates to a structure of a vacuum interrupter, in particular to a combination of a traditional vacuum interrupter and a double repulsion disc, which mainly has the function of self-breaking. Background technique [0002] The vacuum interrupter is the key component of the vacuum circuit breaker, which plays a pivotal role in the power system. Its main function is to use the good insulation performance of the vacuum inside the tube to quickly extinguish the arc and suppress the current after the line is cut off to avoid accidents. It has the advantages of light weight, small size, fire prevention, explosion protection, low failure rate, environmental protection and no pollution. [0003] The traditional vacuum interrupter only includes the main part of the vacuum bubble, and needs to cooperate with a specific operating mechanism to perform the arc extinguishing operation. The overall structure is relatively complicated and the immediacy is...
