Modular intelligent testing device for medium-voltage switch in nuclear power station

Abstract

The invention discloses a modular intelligent testing device for a medium-voltage switch of a nuclear power station. The device comprises a microcomputer module, an interface control module, a switchmechanical characteristic tester and an insulation resistance testing module which are independent from one another in physical structure and are quickly assembled through interfaces arranged on the modules, and the combination function is achieved. Compared with an integrated testing device, the testing device is advantaged in that the size is small, the weight is light, carrying is convenient, combination is flexible, and a testing problem of the medium-voltage switch of the nuclear power station in some narrow environments is effectively solved; moreover, an operation test of an electricalswitch of an overhaul program can be automatically completed, all operation test steps of the switch are fully automatically completed, paperless test is realized, tedious operation procedures such aswire disassembly and connection and manual measurement are omitted, related data of the test device is uploaded to a cloud end for management, and the intelligent degree is high.

Description

technical field [0001] The invention relates to the technical field of medium-voltage switch detection in nuclear power plants, in particular to a modularized intelligent test device for medium-voltage switches in nuclear power plants. Background technique [0002] Nuclear power is a low-carbon and environmentally friendly clean energy. In the process of generating electricity, nuclear power does not produce air pollutants such as sulfur dioxide, nitrogen oxides, and smoke, and the emission of carbon dioxide is much lower than that of thermal power. It has become one of the important energy sources used by people. The stable operation of medium-voltage switches in nuclear power plants guarantees the safe operation of key equipment in nuclear power plants to a certain extent, thereby ensuring nuclear safety. However, the existing medium-voltage switch test methods for nuclear power plants still have the following shortcomings: 1. The current medium-voltage switches for nucle...

AI Technical Summary

Problems solved by technology

However, the existing medium-voltage switch test methods for nuclear power plants still have the following shortcomings: 1. The current medium-voltage switches for nuclear power plants are mainly medium-voltage circuit breakers and medium-voltage contactors, and the detection of medium-voltage circuit breakers and medium-voltage contactors The method is to use instruments to measure the relevant characteristics one by one. After each test, the test results must be manually recorded, and the wiring must be rewired when the next test item is performed. This manual test method is not only heavy workload, low efficiency, and It is easy to connect the wrong wires, and it is dangerous

2. Although some test devices can realize centralized testing of multiple medium-voltage switch test items, these test devices are relatively large in size and not easy to transport, and when testing is required in some small spaces in nuclear power plants, sometimes Encountered the problem that the test device cannot enter, which restricts the application environment of the test device to a certain extent
