A high-voltage switchgear test module

Abstract

The invention belongs to the field of high-voltage switchgear test, and provides a high-voltage switchgear test module, which is used to solve the problem of misoperation and inconvenient operation in the active measurement of the multimeter during the debugging process of the secondary circuit of the high-voltage switchgear. The test module includes: a control circuit and a control switch KK, a circuit detection unit XS, and a high-voltage live detection unit GY; both the circuit detection unit XS and the high-voltage live detection unit GY are electrically connected to the control circuit; the circuit detection unit XS is used for Detect the preset connection state of the external circuit of the high-voltage switchgear and measure the voltage of the external circuit of the high-voltage switchgear; the high-voltage live detection unit GY is used to output the preset voltage and detect the connection of the external circuit of the high-voltage switchgear under the preset voltage Is it connected correctly by default. This module can realize the on-off measurement, voltage measurement and high-voltage live detection of the external circuit, which can effectively improve the convenience and work efficiency of the test.

Description

technical field [0001] The invention belongs to the technical field of electrical equipment, and in particular relates to a high-voltage switch cabinet test module. Background technique [0002] High-voltage switchgear is an important control and protection equipment of the power system, which plays an important role in the safe and reliable operation of the power system. Therefore, the power system requires high reliability and strict quality control. Each product must be strictly tested in accordance with the relevant national and industry standards to meet the design and standard requirements before it can be used by users. [0003] In the secondary circuit debugging of high-voltage switchgear, when the circuit has a fault, it is generally necessary to use a multimeter to measure the circuit parameters to find the problem. The results can be viewed through the meter or LCD display. In the process of use, there are troublesome gear conversions and misoperations, such as...

AI Technical Summary

Problems solved by technology

In the process of use, there are troubles in shifting gears and misoperations, such as measuring voltage in the resistance range, which will damage the multimeter; the display screen of the multimeter also has the problem of inconvenient viewing

[0004] In addition, the high-voltage live display function test in the high-voltage switchgear test process is currently tested by simulating high voltage on site. In the absence of simulated high voltage, the correctness of the circuit can only be verified by actual power-on operation. Failure during the high-voltage test after power-on operation will lead to further problems in disassembly and maintenance, and the operation is complicated, and it has not reached the problem of complete debugging before the high-voltage switchgear is used.
