Relay protection networking maintenance error correction system

Abstract

The invention provides a relay protection networking maintenance error correction system which comprises a detection device, an induction device, an inspection device, an early warning device, a processing device and a processor. The detection device is configured to detect networking parameters, and the induction device is configured to induct the sequential arrangement of the networking parameters; the inspection device is configured to acquire parameters in a networking cabinet, the early warning device is configured to trigger an early warning signal based on data of super early warning detected in the networking cabinet, and the processing device is configured to process based on the early warning signal of the early warning device. Through the cooperative use of the induction deviceand the inspection device, the whole system can perform self-inspection in the operation process, and the sequence of the connecting wires and the relay protection devices can be detected in the detection process so as to ensure the operation safety of the whole equipment.

Description

technical field [0001] The invention relates to the technical field of relay protection, in particular to a system for overhauling and correcting a relay protection network. Background technique [0002] Relays are generally composed of iron core, coil, armature, contact reed and so on. As long as a certain voltage is applied to both ends of the coil, a certain current will flow through the coil, thereby generating an electromagnetic effect, and the armature will overcome the pulling force of the return spring and attract to the iron core under the action of electromagnetic force, thereby driving the armature The moving contact and the static contact (normally open contact) are sucked together. [0003] Such as CN107248480B prior art discloses a relay that is easy to overhaul. During the long-term use of the relay, when the relay body breaks down, the shell needs to be disassembled, and then the relay body is taken out, so that maintenance can be carried out.

Problems solved by technology

[0003] Such as CN107248480B prior art discloses a relay that is easy to overhaul. During the long-term use of the relay, when the relay body breaks down, the shell needs to be disassembled, and then the relay body is taken out, so that maintenance can be carried out. Then install it in the shell, which is very troublesome and a waste of time

Another typical prior art such as WO2015158165A1 discloses a relay protection fixed value visualization method, and an intelligent relay protection device detection method and system disclosed in the prior art such as WO2014108002A1, digital relay protection test The test data output by the instrument cannot simulate the transient process of electrical quantities under some working conditions in substations, so it is impossible to carry out effective dynamic performance tests on intelligent relay protection devices. Due to the limitations of system structure and scale, the test objects have relatively large limitations, the test flexibility is poor, and it is impossible to carry out testing work on-site in smart substations

[0004] In order to solve the common problems in the field such as difficulty in maintenance, inability to perform self-inspection, inability to act and alarm when a fault occurs, poor flexibility and single application scenarios, etc., the present invention is made
