Abstract

The invention discloses an arc extinguish chamber with high current-carrying capability for high-voltage switch equipment. In the chamber, the outermost layer is an insulating support part with metal inserts at two ends, and comprises the metal inserts at two ends thereof; a movable contact system and a static contact system of the arc extinguish chamber are arranged inside the insulating supportpart, and are coaxial with the insulating support part; and the metal insert at the static end of the insulating support part is connected with the static contact system of the arc extinguish chamber, while the metal insert at the movable end is connected with the movable contact system of the arc extinguish chamber. The arc extinguish chamber adopts the metal inserts guiding current of a main loop to the insulating support part and the method for improving conductive part materials and structures in the main loop, so that the cross section of diversion can be increased, the loop resistance can be reduced, the radiating condition can be improved, and the whole through-flow capability of the arc extinguish chamber can be reinforced.

Description

Technical field:

[0001] The invention belongs to the field of high-voltage equipment, and relates to a component for high-voltage switchgear. The component is an arc-extinguishing chamber used by a high-voltage circuit breaker, especially an arc-extinguishing chamber with high current-carrying capacity that needs to pass a large rated current. Background technique:

[0002] The arc extinguishing chamber is a must-use component of the high-voltage circuit breaker. It is the core component for the above-mentioned equipment to complete various functions. Its function is to break, close and carry the normal current of the operating line through this component, and to Carrying, breaking, and closing specified abnormal currents, and then realizing the control and protection of power transmission and transformation lines and equipment. It is one of the basic functions of the arc extinguisher to carry the normal operating current of the transmission line for a long time, and the cur...
