Safe guarding device for power relaying protection field work

Abstract

The invention discloses a safe guarding device for a power relaying protection field work and a use method thereof. The safe guarding device comprises a guarding device and an isolating device, wherein the guarding device is used for maintaining the work, and the isolating device is used for operating the work. The guarding device for maintaining the work comprises a secondary cable core guardingcap, a guarding cap, a terminal block guarding fence and a protection work voice prompter, which are used for protecting a cable core, a pressing plate and a terminal block. The isolating device for operating the work comprises a protecting screen safety isolating guardrail, a protecting device isolating cover, a protecting pressing plate isolating cover, a terminal block isolating cover, a secondary security isolating cover, a CT externally attached terminal isolating cover, a security temporary storage box, a working signboard and an operation handle isolating cover, which are used for isolating and protecting equipment. Each guarding device is adhered with a marking note corresponding to the work state. The safe guarding device has the advantages of fixation, reliability, obvious mark,simple operation, norm and cleanness, and no influence to operation of the equipment by a magnetic field of a magnet, and is suitable for isolating and protecting various kinds of relay protection equipment and devices.

Description

technical field [0001] The invention relates to a protection device and a use method in the electric power industry, in particular to a safety protection device and a use method for on-site operation of relay protection professionals in the power industry. Background technique [0002] The equipment in the power industry is mainly divided into equipment for high-voltage operation and relay equipment for controlling high-voltage operation. Relay equipment is also called secondary equipment. The normal operation of relay equipment is the guarantee for the normal operation of electric power. Maintaining the normal operation of relay equipment needs to be completed by operating personnel and professional protection personnel. The operating personnel are responsible for the normal operation of the operating equipment, and the protection personnel are professional repair and maintenance personnel who are responsible for the maintenance of out-of-service equipment. Relay protection...

AI Technical Summary

Problems solved by technology

Arranging fences in the protection room is not only time-consuming and laborious, but also brings inconvenience to the passage of professional protection personnel; when the red curtain isolates the operating equipment, it is easy to fall off and cannot be fixed, and hinders the monitoring of the operating equipment; these measures are very inconvenient to implement

At the same time, the secondary measures for the on-site operations of the protection personnel are not ideal. The thread ends temporarily removed by them are only wrapped with adhesive tape, which cannot be effectively protected, and there is a possibility of accidental contact; Isolation, there is a possibility of mistaken investment and false return

The components and wire ends wrapped with insulating tape still have the problem of poor conduction after the tape is removed, and cause waste of tape

A relay protection cabinet may have multiple secondary fuses, air switches, circuit breakers, pressure plates, terminal blocks, etc. Some devices need to be repaired, while some devices are running at the same time. If they are not clearly marked and isolated, it is possible Mishandling or misoperation will cause inevitable safety accidents

The secondary measures on the relay protection site have been imperfect, which has troubled protection and operation personnel for a long time
