Problems solved by technology

[0003] At present, when substation operators measure the voltage at both ends of the outlet pressure plate, they use a high-resistance multimeter, and then judge whether the outlet pressure plate can be put in according to the voltage at both ends measured by the multimeter. Judging by relevant knowledge is very easy to cause wrong judgment due to memory deviation, which will lead to misplacement of the outlet pressure plate and affect the safe operation of the substation

Abstract

The invention discloses a measurement indicating device and method for a relay pressure plate. The measurement indicating device for the relay pressure plate comprises a measurement module, a control module, an image acquisition module and a display module. The image acquisition module is electrically connected with the control module and is used for acquiring identification information of a to-be-tested relay pressure plate. The measuring module is electrically connected with the control module and is used for measuring the voltage of the first end and the voltage of the second end of a to-be-tested outlet pressure plate; and the control module is used for determining an input judgment result of the to-be-tested outlet pressure plate according to pre-stored data information of the to-be-tested outlet pressure plate, the voltage of the first end of the to-be-tested outlet pressure plate and the voltage of the second end of the to-be-tested outlet pressure plate. According to the measurement indicating method of the relay pressure plate provided by the embodiment of the invention, mistaken input of the to-be-detected outlet pressure plate caused by deviation of related knowledge memorized by an operator when the operator is used for judging whether the to-be-detected outlet pressure plate is switched on or not can be avoided, so that the input accuracy of the to-be-detected pressure plate is improved, and the safe operation of a transformer substation is ensured.

Description

technical field [0001] The embodiments of the present invention relate to the technical field of relay protection, and in particular to a measuring and indicating device and method for a relay maintaining pressure plate. Background technique [0002] The outlet pressure plate of the substation protection device is an important part of the protection circuit, mainly referring to the protection trip pressure plate, the start-up failure pressure plate, the failure joint trip pressure plate, etc. When the protection device has action contacts stuck or the action relay does not return, the substation operator If Putting the outlet pressure plate in without measurement will cause the circuit breaker to trip by mistake, causing unnecessary losses and affecting the safety and stability of the power grid. Therefore, when it comes to the operation of re-commissioning the outlet pressure plate, the substation operator needs to measure the voltage at both ends of the pressure plate befo...
