Electric-generator-electrical-test area interlocking system and operation method thereof

Abstract

The invention relates to an electric-generator-electrical-test area interlocking system and an operation method thereof. The interlocking system comprises a test equipment power lock jointly opened orclosed with a first key and a second key and used for locking a power circuit breaker of test equipment, a test equipment door lock opened or closed with the first key, a ground wire plug lock connected with a ground wire and opened or closed with the second key, a test equipment grounding lock opened or closed with a third key and used for locking the ground wire plug lock to be inserted into alock body of the test equipment grounding lock and an electric-generator outgoing line cabin door lock opened or closed with the third key. According to the electric-generator-electrical-test area interlocking system and the operation method thereof, the multiple locks are arranged in an electric-generator-electrical-test area, the corresponding keys are matched according to all the locks to achieve the interlocking effect, it is avoided that electrical-test persons forget to ground high-voltage testing equipment, or an electric shock accident is caused when power supply is powered off to enter an electric-generator outgoing line cabin, and safety of testers is guaranteed.

Description

technical field [0001] The invention relates to the field of electrical testing of generators, and more specifically relates to an interlocking system for electrical testing areas of generators and an operation method thereof. Background technique [0002] When conducting high-voltage electrical tests on generators, such as DC withstand voltage tests on generator stators. During the test, when the person in charge of the test needs to enter the test area to perform work such as changing wires or disconnecting wires, it is necessary to disconnect the power supply of the test equipment and ground the high-voltage test equipment in the test area before working. The outlet warehouse on another floor below. When he went to work on the floor below, if he forgot to ground the test equipment or disconnected the power supply and then entered the outlet compartment of the generator, it would cause an electric shock accident. In addition, after the wiring is completed, if you forget ...

AI Technical Summary

Problems solved by technology

When he goes to work on the floor below, if he forgets to ground the test equipment or disconnect the power supply and then enters the outlet compartment of the generator, it will cause an electric shock accident

In addition, after the wiring is completed, if you forget to remove the grounding wire of the test equipment and power on the test equipment, it will cause a short circuit accident of the test equipment to the ground.
