Problems solved by technology

In existing substation design, protective devices of different intervals are often installed on the same protective screen to save space and cost of screen cabinets. When operating the protective device of the equipment, there is a risk of accidentally touching and misoperating the protective device of the operating equipment, especially the front panel with operation buttons and the back panel with secondary wiring. For example, when it is necessary to adjust the value of the protective device for maintenance to the running protection device, or mistakenly touch the secondary line of the running protection device backboard when working on the backboard of the overhauled protection device, it is very likely to cause protection malfunction or refusal to operate, resulting in accidents and greater economic losses. loss, so it is necessary to take isolation protection measures for the panel and back panel of the protection device to avoid accidental touch and misoperation of the running protection device on the same screen during maintenance.
[0003] At present, there are two kinds of isolation protection measures for protection devices commonly used in the field. One is to paste the printed A4 paper with the words "operating equipment" on the panel and back panel of the operating protection device with adhesive tape to warn and prevent misuse. The function of the operation, its defects are: (1) too random, not beautiful after use, (2) the words "operating equipment" printed on the spot are black, there is no strong warning in red words, (3) it is pasted on the protective cover When installing the back panel, it may touch the secondary line on the back panel, and at the same time, the A4 paper will also press on the secondary line of the back panel, which may cause the secondary line to loosen.
Another isolation protection measure for the protection device is to make a red cloth curtain of the corresponding size, and the four corners use magnets, which can be adsorbed on the iron plates on both sides of the protection device to warn and prevent misuse. Its defects are: (1) The red cloth curtain is an opaque structure, which will hinder the operating personnel from observing the protective device during operation. (2) The red cloth curtain is made of soft material. If the operator accidentally touches the cloth curtain during maintenance, it is easy to make mistakes Press the button of the guarded protective device, causing a certain risk on the

Abstract

The invention relates to the technical field of electric power, in particular to an isolating protection cover for a rear panel of a protection device. The isolating protection cover is composed of two completely identical supporting frames (1) and a warning board (2). The problem about protection of a protection device mounted on a rear panel is mainly solved. The isolating protection device mainly has the advantages that misoperation can be alerted and stopped, the probability of safety accidents is reduced, the operating safety of a power grid is protected, the structure is simple, production is easy, carrying is convenient, and storage and use are convenient and fast.

Description

technical field [0001] The invention belongs to the technical field of protection devices for electric equipment operation, and in particular relates to an isolation protective cover for the rear panel of the protection device. Background technique [0002] In the power system, the relay protection device is used to protect the power system and its components (generators, transformers, transmission lines, busbars, etc.) safe operation of power systems. In existing substation design, protective devices of different intervals are often installed on the same protective screen to save space and cost of screen cabinets. When operating the protective device of the equipment, there is a risk of accidentally touching and misoperating the protective device of the operating equipment, especially the front panel with operation buttons and the back panel with secondary wiring. For example, when it is necessary to adjust the value of the protective device for maintenance to the running...
