Problems solved by technology

[0002] Circuit breakers are widely used electrical products, and they are in great demand. However, the current testing process is still in a relatively primitive state. Each circuit breaker is inconvenient to test with manual wiring, assembly and disassembly, and the efficiency is extremely low. Not only is it a serious waste of manpower , also makes the test cost high, which seriously hinders the development of production, so it is urgent to develop an efficient and reliable circuit breaker test device

Embodiment Construction

[0025] The present invention will be further described in detail below in conjunction with the structural diagram of the appendix.

[0026] see figure 1 , figure 2 and image 3 , the fixture device of the circuit breaker automation test bench includes a contact piece assembly [1], a bottom plate [2], a linear guide [3], a compression spring [4], a floating bracket [5], a follower slide [6], etc. components.

[0027] The contact piece assembly [1] is a structural member composed of two reeds and the assembly base. The reeds are installed on both sides of the assembly base. The surface of this part of the reed installed on the side of the assembly base is provided with two round holes. It is installed on the side of the base with screws, and the other part of the reed is used to contact the contact piece on the circuit breaker under test, and its bending angle is consistent with that of the circuit breaker contact piece to ensure the largest contact area and eliminate the co...

Abstract

The invention belongs to testing technology and relates to a high and low temperature performance testing device of a circuit breaker. It is characterized in that it consists of a contact piece assembly [1], a bottom plate [2], a linear guide rail [3], a compression spring [4], a floating bracket [5], and a follower slide [6]. The invention is used for rapid testing of the high and low temperature performance of circuit breakers. Ten circuit breakers can be tested at the same time by one clamping. The reed made of beryllium bronze alloy and the floating installation structure are used to ensure the test requirements of the circuit breaker contact resistance, and the structure is simple. , easy to operate, high test efficiency.

Description

technical field [0001] The invention belongs to testing technology, in particular to a high and low temperature performance testing device for a circuit breaker. Background technique [0002] Circuit breakers are widely used electrical products, and they are in great demand. However, the current testing process is still in a relatively primitive state. Each circuit breaker is inconvenient to test with manual wiring, assembly and disassembly, and the efficiency is extremely low. Not only is it a serious waste of manpower , also makes the test cost remain high, which seriously hinders the development of production, so it is urgent to develop an efficient and reliable circuit breaker test device. Contents of the invention [0003] The object of the present invention is to provide a circuit breaker high and low temperature performance test device, which is used for the high and low temperature performance test of the circuit breaker. It is required to meet the requirements of...
