Abstract

The utility model provides a field application type overhauls division board, can full play warning, keep apart, prevent mistake and bump, prevent an effective isolating device of maloperation when arranging with the screen based on overhauing on-the-spot many interval protection device, solved and overhauld the potential safety hazard, the division board comprises main frame and a plurality of window, installs a plurality of windows through metal hinge setting on the main frame, and the main frame passes through the magnetic stripe laminating around the protection screen cabinet. The device can improve the working efficiency and avoid the bad consequences caused by repeated reworking and misoperation. Therefore, the successful application of the 35 KV multi-device operation and maintenance isolation plate greatly improves the production efficiency, reduces the labor intensity of personnel and reduces the cost.

Description

On-site application type overhaul isolation plate

Technical Field

The utility model relates to a master control room protection cabinet interval protective apparatus technical field specifically is a site application type overhauls division board.

Background

Because the running time of each protection device of the transformer substation is too long, the work of transformation and program upgrading aiming at the protection devices of the transformer substation is increased, and the work on the protection screen cabinet in the transformer substation is more frequent. The 35 KV four-side protection screen cabinet in the main control room of the transformer substation is generally provided with a plurality of spaced protection devices, when the 35 KV four-side protection screen cabinet works on one protection device, a sign plate is hung in the traditional method, the sign plate can only play a warning role obviously and cannot form effective isolation, and the condition that other operation protection devices are mistakenly operated by maintainers still exists.

SUMMERY OF THE UTILITY MODEL

The utility model provides a site application type overhauls division board, the effectual maintenance potential safety hazard of having solved, through adopting division board equipment, can make the maintainer clearly and definitely distinguish the maintenance interval, prevent that the mistake from bumping, maloperation equipment, and then prevent the emergence of maloperation accident.

In order to achieve the purpose, the technical scheme adopted by the application is as follows:

the utility model provides a field application type overhauls division board which characterized in that: the division board comprises main frame 1 and a plurality of window 3, installs a plurality of windows 3 through metal hinge 2 setting on main frame 1, and main frame 1 passes through the laminating of magnetic stripe 5 around the protection screen cabinet.

The window 3 is a double-opening door and window opening.

An identification clamping groove 4 is formed in the window 3, and the identification clamping groove 4 is used for placing an identification plate.

The utility model has the advantages that: this device adopts the switch principle of window, utilizes the hinge to drive the isolation window, can realize the isolation to protection device maintenance interval and operation interval, and the installation is dismantled conveniently. The operation is simple, the opening and closing can ensure the effective isolation of each interval protection device, and the isolation effect is obvious; the misoperation risk is reduced, and the reliability of running equipment is ensured; the secondary safety measure arrangement is simplified, and the safety measure errors of operators are reduced; the abnormal operation of other protection devices caused by misoperation is avoided; the power failure loss and the electric quantity loss can be reduced; the power supply reliability of the user is improved. After the device is used, the working efficiency can be improved, and adverse consequences caused by repeated reworking and misoperation can be avoided. Therefore, the successful application of the 35 KV multi-device operation and maintenance isolation plate greatly improves the production efficiency, reduces the labor intensity of personnel and reduces the cost.

Drawings

FIG. 1 is a schematic structural view of the present invention;

FIG. 2 is a front view of the present invention;

fig. 3 is a rear view of the present invention;

shown in the figure: the device comprises a main frame 1, a metal hinge 2, a window 3, an identification clamping groove 4 and a magnetic stripe 5.

Detailed Description

The technical solution of the present invention is further described by the following specific embodiments with reference to the accompanying drawings:

example 1

An on-site application type maintenance division board as shown in figures 1-3 has the following specific structure:

the main frame 1 is pasted on a 35 KV square protection screen cabinet of a main control room of a transformer substation through a plurality of transverse and longitudinal magnetic stripes 5. The magnetic strip 5 is a detachable magnetic strip, and the magnetic strip is detached and installed according to the use conditions.

A plurality of windows 3 are mounted on the main frame 1 through metal hinges 2. The window 3 adopts a double-door type window, the operation is simple, the effective isolation of each interval protection device can be ensured by opening and closing, and the isolation effect is obvious; the misoperation risk is reduced, and the reliability of the running equipment is ensured.

The window 3 is provided with a marking card slot 4, the marking card slot 4 is used for placing a signboard, and the signboard generally adopts 'operation equipment' and 'work here' signboard.

The method comprises the following specific steps:

1. when the maintenance work is not carried out on site, all windows are closed, and the mark card in the clamping groove indicates 'operating equipment';

2. when the device at a certain position is overhauled on site, the marking card in the clamping groove of the window at the position is taken down, the double doors are opened, and the marking card is placed back into the clamping groove and is shown to work at the position.

3. And after the field maintenance work is finished, taking down the marking card in the clamping groove, closing the double doors, and putting the marking card back to the clamping groove to seal the window and show that the equipment is operated.

It is obvious to a person skilled in the art that the invention is not restricted to details of the above-described exemplary embodiments, but that it can be implemented in other specific forms without departing from the spirit or essential characteristics of the invention. The present embodiments are therefore to be considered in all respects as illustrative and not restrictive, the scope of the invention being indicated by the appended claims rather than by the foregoing description, and all changes which come within the meaning and range of equivalency of the claims are therefore intended to be embraced therein. Any reference sign in a claim should not be construed as limiting the claim concerned.

Furthermore, it should be understood that although the present description refers to embodiments, not every embodiment may contain only a single embodiment, and such description is for clarity only, and those skilled in the art should integrate the description, and the embodiments may be combined as appropriate to form other embodiments understood by those skilled in the art.
