Research on Multi Position and Parallel Detection Device for Universal Circuit Breaker Controller

This paper introduces a design scheme of the residual current electrical fire monitoring detector performance test system based on virtual instrument technology. In order to test different current specifications monitor detector compatiblly,the system combines virtual instrument technology and computer control technology to improve the accuracy of output current of the current generator with electric voltage compensation technology and the way of closed-loop control ,and designs two sets of different size and the same type of pneumatic fixture to solve the connection of different specifications monitoring detector, software design adopts layered structure and the method based on configuration files, to better satisfy all kinds of test requirements for different products. Practical application shows that the system has the testing results of accurate, high efficiency and convenient operation.
