CN203086025U - Voltage plate safety measure insulating cover for electric power line protection - Google Patents

Abstract

The utility model relates to an isolation cover for safety measures of a power line protection pressure plate. Its technical solution is: including a shell and a gland, the top of the shell is provided with a gland, the bottom is open, the gland is a left and right split structure, the left gland and the right gland can slide relative to each other, and the gland is provided with There is a display light, and a card slot is arranged inside the casing, and a magnet is arranged in the card slot. The beneficial effect is that the isolation cover for the safety measure of the power line control switch can replace the previous method of covering the operation control switch by the operator with a red curtain, and directly cover the operating line control switch with the isolation cover with magnets, thereby improving the safety facilities of the operation line control switch The fast setting speed prevents maintenance personnel from touching the operation control switch by mistake, and improves the standardization of safety facilities. The left gland and the right gland can slide relative to each other, and can adapt to power line protection pressure plates of different sizes.

Description

Power line protection pressure plate safety measures isolation cover

technical field

The utility model relates to a protective device for relay protection and maintenance of an electric power system, in particular to an isolation cover for safety measures of a pressure plate for electric line protection.

Background technique

In the current line protection with a voltage level of 110 kV and below, most of the protections for two or more outgoing lines are installed in a set of screen cabinets. When one of the protections is working, in order to prevent maintenance personnel from accidentally operating other lines Switches need to take safety measures for the control switches of the operating lines. The "little red curtain" used in the past has the disadvantages of easy falling off, irregularities, and unclear boundaries when covering. In order to solve this problem, it is necessary to develop a standardized "electric power The line control switch safety measure isolation cover" effectively isolates the operation control switch, achieves the purpose of safety, reliability, convenient use, eye-catching specifications, and effectively prevents misoperation by maintenance personnel.

Contents of the invention

The purpose of this utility model is to provide a power line protection pressure plate safety measure isolation cover for the above-mentioned defects in the prior art.

Its technical solution is: including a shell and a gland, the top of the shell is provided with a gland, the bottom is open, the gland is a left and right split structure, the left gland and the right gland can slide relative to each other, and the gland is provided with There is a display light, and a card slot is arranged inside the casing, and a magnet is arranged in the card slot.

The beneficial effects of the utility model are: the isolation cover for the safety measure of the power line control switch can replace the previous method of covering the operation control switch with a red cloth by the operator, and directly cover the operating line control switch with the isolation cover with magnets, thereby improving the operating line. Control the setting speed of switch safety facilities, prevent maintenance personnel from accidentally touching the operation control switch, and improve the standardization of safety facilities. The left gland and right gland can slide relative to each other, and can adapt to power line protection pressure plates of different sizes.

Description of drawings

Accompanying drawing 1 is the structural representation of the utility model;

In the figure above: housing 1, left gland 2, right gland 3, display light 4, magnet 5, card slot 6.

Detailed ways

In conjunction with accompanying drawing 1, the utility model is further described:

The utility model includes a housing 1 and a gland. The top of the housing 1 is provided with a gland, and the bottom is open. The gland is a left and right split structure. The left gland 2 and the right gland 3 can slide relatively. The cover 3 is provided with a display light 4 , and the inside of the housing 1 is provided with a card slot 6 , and a magnet 5 is provided in the card slot 6 .

The size of the isolation cover of the utility model is consistent with the actual control switch. The material is made of high-strength transparent acrylic board. The whole adopts a groove design. The magnet is placed in the card groove, which is tightly connected and not easy to fall off. When in use, put the switch isolation cover directly on the control switch, the magnet is closely connected with the protection plate, and the display light on the front panel plays a very good warning role, preventing misoperation visually, because the isolation cover is tightly buckled The control switch, the maintenance personnel cannot directly touch the control switch of the running line at all, making it impossible to misuse it, and it is standardized and beautiful, achieving the expected effect.
