Portable power switch state simulation testing device

Abstract

The invention discloses a portable power switch state simulation testing device which comprises a remote control input circuit, a relay logic circuit, a power switch position display circuit, a telecommand output circuit and a power circuit, wherein the remote control input circuit is electrically connected with the relay logic circuit, the output end of the relay logic circuit is electrically connected with the power switch position display circuit and the telecommand output circuit respectively, and the power circuit supplies power to circuits of all the units. The portable power switch state simulation testing device has the benefits as follows: the relay logic circuit is adopted for realizing targeted testing of a remote control telecommand function, so that the life loss caused during actual control of a circuit breaker is reduced, and the problem that the switch state cannot be simulated in the distribution automation debugging process is further solved; and a safety handle is further added to the testing device, so that the handhold function can be realized, a human body is effectively isolated from the live part of equipment, the use safety is improved, the urgent need of the technical field is met, and the working efficiency is improved.

Description

technical field [0001] The invention relates to the professional technical field of power equipment scheduling automation; in particular, it relates to a portable power switch state simulation test device. Background technique [0002] With the continuous improvement of power dispatch automation technology, the maturity of substation comprehensive automation technology, and the in-depth advancement of distribution automation transformation, the development trend of smart grid is beyond doubt. As the "messenger" of information transmission, the measurement and control device plays an important role, which puts forward new requirements for the reliability of the measurement and control device, especially for important control signals such as remote control and remote signaling of circuit breakers or load switches, it must be accurate It is transmitted downward through the measurement and control device, but so far, there is no test device or equipment for simulating the switch...

AI Technical Summary

Problems solved by technology

For example, in the process of substation acceptance and commissioning, the execution of the remote control command can only be judged by the opening and closing of the actual circuit breaker, but the actual frequent opening and closing of the circuit breaker will seriously affect the service life of the circuit breaker

For another example, in the transformation process of power distribution automation, since the load switch is not allowed to be disconnected, the signal can only be simulated by means of a multimeter or a short contact, which is very inconvenient and easy to misuse. Based on the above, there is an urgent need for a Portable power switch state simulation test device
