Abstract

The present invention relates to a high-voltage program control matrix switch. The switch comprises a serial port conversion module, a communication processing module, a driving module, a relay matrix and a display module, the serial port conversion module is connected with the communication processing module for transmission of switch information, the display module is connected with the communication processing module for display of a switch state, the driving module is connected with the communication processing module to receive and latch the switch state information to drive the relay matrix to perform switching motion, and an upper computer is configured to send the switch motion information and receive the switch state information in parallel through a serial port. The low-voltage driving high relay is employed to satisfy switching and test demands of high-voltage signals, the modularization design is employed to allow the high-voltage program control matrix switch to have good development, and the feedback information is compared to realize rapid location of faults of a module channel.

Description

technical field [0001] The invention relates to a fast switching module for multi-channel high-voltage insulation signals, in particular to a high-voltage program-controlled matrix switch. Background technique [0002] At present, the matrix switch used for signal switching in test equipment is mainly for low-voltage and weak signals. It mainly uses analog electronic switches or small relays, and uses PCI, PXI and other backplane bus interfaces to realize the control of the switch module, which can be used in a limited space. Realize high-speed, multi-channel signal switching. However, for testing equipment for high-voltage signals, especially when performing insulation tests on products, the commonly used matrix development module cannot meet the testing requirements of the equipment, so it is necessary to study and design a switch module that meets high-voltage switching. [0003] As a matrix switch for high-voltage switching, in addition to having the programmable charac...
