Protective device defect eliminating coordination instrument without circuit power outage

Abstract

The invention discloses a protective device defect eliminating coordination instrument without circuit power outage, and belongs to the technical field of circuit protective devices. The protective device defect eliminating coordination instrument without the circuit power outage at least comprises a protective device replacing unit, a detection unit, a control unit and a state indicating unit, wherein the protective device replacing unit is used for replacing an abnormal protective device appears in a circuit, the detection unit is used for detecting the replacement protective device unit or the repaired abnormal protection device to ensure normal working, reliable action and correct indicating, and transmitting the current checking states to the state indicating unit, the control unit is used for sending out detection control instructions, and controlling the working state of the detection unit, and the state indicating unit is used for displaying current working operation states. The protective device defect eliminating coordination instrument without circuit power outage solves the problems that previously, an operation switch and the circuit have to be powered off so that the failure of the protective device can be handled, power supply reliability is influenced, and potential hazards of accidents are laid for the safety operation of equipment. The protective device defect eliminating coordination instrument without circuit power outage has the advantages of being simple in structure, convenient to use, high in efficiency and capable of improving power sale quantity and circuit reliability.

Description

technical field [0001] The invention belongs to the technical field of circuit protection devices. Background technique [0002] At present, when the 35kV, 10kV and below line protection devices have device abnormalities, or telemetry data, protection and circuit breaker position signals cannot be uploaded, and switches cannot be remotely controlled, etc., the dispatch monitoring will convey the defects to the maintenance work area; handle the above defects It is necessary to stop the switch to eliminate the defect of the equipment (hereinafter referred to as the defect elimination), which will cause a power outage to the user, which not only affects the normal production and life of the people, but also causes economic losses to the user and the factory, and also reduces the company's electricity sales. economic benefits of the company. However, some important users, such as factories and mines, cannot easily cut off the power. When the protection device has a general fail...

AI Technical Summary

Problems solved by technology

[0003] The technical problem to be solved by the present invention is to provide a line non-stop protection device to eliminate defects, so as to overcome the problem that the previous operation switch and line need to be powered off to deal with the failure of the protection device, which affects the reliability of power supply and cannot smoothly complete the power scheduling and distribution. It has the advantages of simple structure, convenient use, high efficiency, increased electricity sales, and improved line reliability.
