Intelligent display device tester of switch cabinet

Abstract

The invention provides an intelligent display device tester of a switch cabinet. The intelligent display device tester of the switch cabinet comprises a main board, wherein a closed wire connection terminal, a state analog terminal, a load and alarm signal terminal and a sensor signal terminal are arranged on the main board, and a closed analog circuit connected with the closed wire connection terminal, a state analog circuit connected with the state analog terminal, a load and alarm analog circuit connected with the load and alarm signal terminal, and a sensor circuit connected with the sensor signal terminal are further arranged on the main board. According to the intelligent display device tester of the switch cabinet, corresponding testing ports and analog circuits are arranged on the main board, and therefore verification test process is simplified, and production efficiency is improved.

Description

technical field [0001] The invention relates to a test board, in particular to a test board used for a state indicator of a switch cabinet. Background technique [0002] The switchgear is usually equipped with a switchgear status indicator for indicating the status of the switch. This device can realize the live display, dynamic simulation function and locking function of the high-voltage side circuit. At the same time, it integrates temperature and humidity control, display function and voice prompt function. The power distribution link is widely used. [0003] In the production process of the switchgear status indicator, it is necessary to verify and test its various functions, because the switchgear status indicator generally has six analog inputs, temperature and humidity sensor inputs, three phase voltage inputs, one working power supply, one For the load power supply, two passive node outputs and one communication interface, if each interface of the switch cabinet sta...

[0003] In the production process of the switchgear status indicator, it is necessary to verify and test its various functions. Because the switchgear status indicator generally has six analog inputs, temperature and humidity sensor inputs, three phase voltage inputs, one working power supply, one Load power supply, two passive node outputs and one communication interface, if the verification test is performed on each interface of the switchgear status indicator separately, the wiring of each verification test circuit is cumbersome, and the verification test process is inefficient
