Relay protection data monitoring equipment and processing system in power supply network

Abstract

The invention relates to the technical field of circuit protection, in particular to relay protection data monitoring equipment in a power supply network, which comprises a relay monitor main body, a front plate is fixedly mounted at the front end of the relay monitor main body, and clamping mechanisms are arranged on the outer surfaces of the upper, lower and two sides of the relay monitor main body. The clamping mechanism is located behind the front plate, guide rails extending in the two side directions are fixedly installed on the rear end face of the relay monitor body, a sliding plate is slidably installed at the rear ends of the guide rails in a clamped mode, and the sliding plate and the inner sides of the guide rails are positioned through a meshing mechanism. The device can be rapidly and conveniently installed on the power distribution cabinet, has a wiring assisting function, does not cause the problem of disordered wires in the power distribution cabinet, achieves the data monitoring of the relay and the control of a relay circuit, and can control the circuit to be disconnected when abnormal circuit data is detected, thereby achieving the effect of protecting the circuit in time.

Description

technical field [0001] The invention relates to the technical field of circuit protection, in particular to a monitoring device and a processing system for relay protection data in a power supply network. Background technique [0002] The relay is an electric control device, which is an electrical appliance that causes the controlled quantity to undergo a predetermined step change in the electrical output circuit when the change of the input quantity (excitation quantity) meets the specified requirements. It has an interactive relationship between the control system (also known as the input loop) and the controlled system (also known as the output loop). Usually used in automatic control circuits, it is actually an "automatic switch" that uses small currents to control large current operations, so it plays the role of automatic adjustment, safety protection, conversion circuits, etc. in the circuit, that is, it is used in power supply Circuit protection monitoring equipment...

AI Technical Summary

Problems solved by technology

[0003] However, in the prior art, the relay protection method is single, and the configuration of the input quantity is required in advance. It has limitations in the application of complex circuits. It is often used in conjunction with the relay monitor for on-site testing, and the monitor is temporarily connected during use, which is quite inconvenient. Moreover, continuous circuit detection cannot be guaranteed, and the data monitoring in the interface cannot be continuously carried out, and remote control cannot be performed. In addition, during the wiring process, the complicated wiring also makes the on-site wiring confusing, which is not conducive to circuit maintenance.
