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.
[0004] 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

Embodiment 1

[0026] please see Figure 1 to Figure 4 , an isolation protective cover for the front panel of a protective device, consisting of a warning sign 1, a first support frame, and a second support frame; it is characterized in that:

[0027] Described warning sign is cuboid shape, and the width direction one side of warning sign has warning sign first cover plate 101, and the other side of warning sign width direction has warning sign second cover plate 102, and the top of warning sign first cover plate The first magnet 401 is inlaid, the second magnet 402 is inlaid under the first cover of the warning sign, the third magnet 403 is inlaid above the second cover of the warning sign, and the fourth magnet is inlaid under the second cover of the warning sign 404;

[0028] The first support frame is composed of a first support frame strip 201, one end connected to the first support frame upper arc support portion 202 above the first support frame strip, and one end connected to the fi...

Embodiment 2

[0032] please see Figure 5 , and refer to Figure 1 to Figure 4 , an isolation protective cover for the front panel of a protective device, basically the same as in Example 1, the difference is that: the upper arc support part 202 of the first support frame is in the shape of a cuboid, and the lower arc support part 203 of the first support frame is also in the shape of a cuboid , The arc-shaped support part on the second support frame is also in the shape of a cuboid, and the arc-shaped support part on the second support frame is also in the shape of a cuboid; the arc-shaped support part on the first support frame is connected with the strip 201 of the first support frame at an obtuse angle, There is an obtuse angle connection between the lower arc support part of the first support frame and the strip 201 of the first support frame, and an obtuse angle connection between the upper arc support part of the second support frame and the strip 201 of the second support frame. Th...

Abstract

The invention relates to the technical field of electric power, in particular to an isolation shield for a front panel of a protection device. The isolation shield is composed of a warning sign, a first support frame and a second support frame. The invention can provide isolation protection for a relay protection device on a protection screen, so as to prevent the protection device from being accidentally touched during operation on the same screen and further avoid relay protection accidental touch. The isolation shield is simple and practical, and has good market promotion value.

Description

[0001] This application is a divisional application of an invention patent application titled: An isolation protective cover for the front panel of a protective device, the application date is September 24, 2016, and the application number is 201610845972.X. technical field [0002] 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 front panel of the protection device. Background technique [0003] 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 mis...
