Circuit breaker checking table clamp

Abstract

A circuit breaker checking table clamp comprises a clamp support, clamping head copper sheets and a testing power supply. The clamp support is provided with two clamping head groups respectively clamping two rows of buses of a checked circuit breaker, each clamping head group comprises two rows of clamping head copper sheet groups matched with each other to achieve clamping, each row of clamping head copper sheet group comprises at least five clamping head copper sheets corresponding to each clamping head copper sheet in the other row of clamping head copper sheet group of the same clamping head group, and a pair of correspondingly arranged clamping head copper sheets respectively arranged on the two rows of clamping head copper sheet groups forms a clamping head unit. The circuit breaker checking table clamp is quick in checking efficiency and high in automation degree.

Description

technical field [0001] The invention relates to the field of electric appliance calibration, in particular to a fixture for a circuit breaker calibration table. Background technique [0002] Due to the large variety of models and specifications and heavy volume of circuit breakers currently on the market, it is necessary to adjust the phase line spacing between each phase fixture according to the different models of the circuit breaker before each circuit breaker calibration, which increases the calibration process. A preparatory process in the process reduces the efficiency of verification. In addition, the traditional single-phase calibration method is adopted in the industry, that is, one phase of the product is manually moved into the fixture each time, the fixture is clamped, and the calibration is performed. After the calibration is completed, the fixture is released. , and then manually move the other phase of the product to the fixture, clamp the fixture, and perfor...

[0002] Due to the large variety of models and specifications and heavy volume of circuit breakers currently on the market, it is necessary to adjust the phase line spacing between each phase fixture according to the different models of the circuit breaker before each circuit breaker calibration, which increases the calibration process. A preparatory process in the process reduces the efficiency of calibration

In addition, the traditional single-phase calibration method is adopted in the industry, that is, one phase of the product is manually moved into the fixture each time, the fixture is clamped, and the calibration is performed. After the calibration is completed, the fixture is released. , and then manually move the other phase of the product to the fixture, clamp the fixture, and perform calibration. The main defect of this calibration method is that manual phase change is used during phase change, the speed is slow, and the production efficiency is poor. , low product quality consistency
