Abstract
The utility model relates to a high-voltage switch cabinet rear cover with an open-type visual window, comprising a cabinet body rear cover (1), fixing bolts (2) and a visual window (3). The high-voltage switch cabinet rear cover is characterized in that one side of the visual window (3) is provided with a hinge (4), the other side of the visual window (3) is provided with a buckle (5), an electromagnetic lock (6) matched with the buckle (5) is arranged, and the electromagnetic lock (6) is connected with a power supply through a charged display (7). The frame of the visual window (3) is pasted with a sealing strip, and dust cannot enter the inside of the cabinet body due to the sealing strip after the visual window is opened. The visual window can be opened by the use of the electromagnetic lock to carry out electricity testing when equipment is powered off. Therefore, the effects of high maintenance efficiency, convenient operation and low probability of electric shock are achieved, maintenance is convenient, the investment is small, and the effect is very obvious.
Description
Technical field
The utility model belongs to electrical equipment technical field, specifically a kind of high-tension switch cabinet bonnet with visual window and safety lock.
Background technology
High-tension switch cabinet used is all totally enclosed at present, and various instrument are equipped with in cabinet front portion, and A, B, C three-phase copper bar, circuit breaker, electrification display, overvoltage protection device etc. are equipped with in cabinet the inside.For the ease of cabinet the inside equipment component is carried out to spot check, glass visual window is all housed after high-tension switch cabinet, in the process of equipment operation, operations staff can see through glass visual window carry out spot check.In the time of switch cubicle interruption maintenance, according to safety requirements, need to carry out electrical verification to switch outlet, after electrical verification is qualified, can open bonnet, cannot open because of visual window, cannot measure charged situation, impact to maintenance safety.
Summary of the invention
The purpose of this utility model is the problem of not tearing bonnet open and cannot carry out electrical verification in order to solve current high-tension switch cabinet, and a kind of high-tension switch cabinet bonnet of opening type visual window is provided.For achieving the above object, the technical scheme that the utility model adopts is as follows: the high-tension switch cabinet bonnet of this opening type visual window, include cabinet bonnet, set bolt and visual window, it is characterized in that: a side of visual window is provided with hinge, the opposite side of visual window is provided with buckle, be provided with electromagnetic lock with being clasped, electromagnetic lock joins through electrification display and power supply.On the frame of visual window, be stained with sealing strip, after closing, owing to there being sealing strip, dust cannot enter cabinet inside.In the time that switch cubicle has electricity, the normally-closed contact of electrification display disconnects, and the tapered end of electromagnetic lock is inserted in the hole of buckle, and visual window is closed.After switch cubicle has a power failure, electrification display normally-closed contact closure, the button of operation electromagnetic lock, electromagnetic lock energized action, the tapered end of electromagnetic lock exits in the hole by buckle, can operate clasp open window, conveniently it is carried out to electrical verification.
The utility model, in the time that equipment has a power failure, utilizes electromagnetic lock to open visual window and carries out electrical verification, has played the effect that overhaul efficiency is high, easy to operate, be difficult for causing electric shock, and easy to maintenance, invests less effect highly significant.
