Embodiment Construction

[0036] Please refer to the attached figure 1 , with figure 1 A schematic structural diagram of the compound contact of the vacuum interrupter provided by the embodiment of the present application is shown. attached by figure 1 It can be seen that the composite contact of the vacuum interrupter provided by the embodiment of the present application includes a frame-shaped contact 1 and a static end contact 2 . Wherein, the position of the static end contact 2 in the vacuum interrupter is fixed and is always in a static state. The frame-shaped contact 1 can move relative to the static end contact 2, so that the composite contact of the vacuum interrupter is suitable for the opening process and closing process, and realizes the switching function of the vacuum circuit breaker.

[0037] Specifically, the frame-shaped contact 1 is a frame-shaped structure, and the movable end contact 3 is arranged in the hollow thereof, and the movable end contact 3 can slide relative to the fram...

Abstract

The invention provides a vacuum arc extinguishing chamber composite contact, a vacuum arc extinguishing chamber and a vacuum circuit breaker. The vacuum arc extinguishing chamber composite contact provided by the invention employs different contacts of different materials to respectively bear closing high-frequency surge and breaking arc, separation of welding resistant performance and disconnection performance is achieved, so that the insulation strength among the contacts is achieved, the heavy breakdown probability of the vacuum arc extinguishing chamber after current arc disconnection is further reduced. The vacuum arc extinguishing chamber composite contact, the vacuum arc extinguishing chamber and the vacuum circuit breaker, provided by the invention, can be used for a switching capacitance load such as a back-to-back capacitor bank and a single capacitor bank and are more suitable for the field of reactive power compensation of a power system.

Description

technical field [0001] The invention relates to the technical field of electric power equipment, in particular to a composite contact of a vacuum interrupter, a vacuum interrupter and a vacuum circuit breaker. Background technique [0002] There are a large number of capacitive loads and inductive loads in the power system, and these loads will generate a large amount of reactive power during the operation of the power system. Reactive power will cause the system voltage to deviate from the rated value and increase system loss. Therefore, in order to ensure the voltage level of the power system and improve the transmission capacity, reactive power compensation must be carried out. During the actual operation of the power system, the load of the power grid will fluctuate frequently, so the capacitor bank for reactive power compensation will also be frequently put in and removed from the system in order to maintain the stability of the power system voltage. At present, the sw...
