Circuit breaker calibration table fixture

Abstract

The fixture of the circuit breaker calibration table includes a fixture bracket, a copper piece of the clamp and a test power supply. The fixture bracket is provided with two sets of clamps for respectively clamping the two rows of busbars of the circuit breaker to be verified. Each set of clamps It includes two rows of collet copper sheets that cooperate with each other to achieve clamping. Each row of collet copper sheets includes at least five collet copper sheets corresponding to each collet copper sheet in another row of collet copper sheets in the same collet group. The collet copper sheets are provided, and a pair of collet copper sheets correspondingly arranged on the two rows of collet copper sheets respectively form a collet unit. The object of the present invention is to provide a circuit breaker calibration bench fixture with high calibration efficiency and high automation.

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
