Contact base, manufacturing method of contact base and circuit breaker using same

Abstract

The invention relates to a contact base, a manufacturing method of the contact base and a circuit breaker employing the contact base and aims at solving the problem that the connected part of the follow-up contact base and a transmission mechanism is mechanically damaged easily in the prior art. In order to solve the technical problem, a connector of the contact base is arranged on a contact base body through a connection structure, so that materials, such as steel and alloys, with higher strength, or an aluminum material, manufactured by other methods of precision casting and the like, with higher strength can be selected by the connector with relatively high strength requirements; the connector is connected to the contact base body to meet the strength requirements; and the problem that the connector is easily damaged is solved. Meanwhile, the problem of over-high cost of the contact base caused by an overall strength enhancement method is also avoided. Meanwhile, in the manufacturing process of the contact base, the connector is firstly fixed on the contact base body and then a transmission mechanism matching structure is processed on the connector, so that guarantee of the accuracy of the final matching structure is facilitated.

Description

technical field [0001] The invention relates to a contact seat, a method for manufacturing the contact seat and a circuit breaker using the contact seat. Background technique [0002] The static contact seat in the circuit breaker is installed inside the insulating porcelain sleeve of the circuit breaker. When the circuit breaker is closed, the current can flow through the main contact of the circuit breaker, which mainly plays the role of long-term conduction, so the static contact seat of the circuit breaker is required It has good electrical conductivity, considering the electrical conductivity and material characteristics, most of the current static contact seats are made of cast aluminum. In the development process of the circuit breaker, in order to reduce the impact reaction force of the circuit breaker on the operating mechanism during the opening and closing process, such as the self-energy interrupter of the double-acting high-voltage SF6 circuit breaker disclosed ...
