Description

Switch cabinet with inspection window

technical field

The utility model belongs to the technical field of electric equipment, in particular to a switch cabinet.

Background technique

10KV closed switchgear (XGN2-10 type closed switchgear) has a closed observation window on the rear cabinet door, and the line cables and the grounding switch on the line side can be seen through this window.

The closed switch cabinet adopts the indirect electric inspection method, that is, "judging by the changes of the mechanical indication position of the equipment, electrical indication, live display device, instrument and various telemetry, remote signaling and other signals. , among the above criteria, except that the electrification display device can reflect whether the line is charged, other criteria cannot change correspondingly. That is to say: before pushing the grounding knife switch, there is only one criterion for whether the line is charged. "Single criterion "Electrical inspection" can not meet the requirements of safety regulations. If you open the rear cabinet door and directly inspect the electricity, it is simple and easy and does not require investment. Disadvantages: it does not meet the requirements of the "Safety Regulations", and it is easy to cause casualties.

When the high-voltage live indicator light is damaged and the line is charged (if the line is charged), the ground knife (charged ground knife) will burst at this time, the insulating sleeve will burst, the switchgear will explode, and the entire switchgear will be scrapped, which will cause: personal injury, equipment damage, Power outages for users and a large amount of capital investment. Therefore, reducing potential threats, ensuring the safety of operators and equipment, and solving the problem of single-criteria electrical inspection when the line is transferred from standby to maintenance have become urgent problems to be solved.

Contents of the invention

The purpose of the utility model is to provide a switch cabinet with an electric inspection window, which can be directly inspected and has good safety.

In order to achieve the above purpose, the technical solution adopted by the utility model is: a switch cabinet with an electroscope window, which includes a switch cabinet body, and an observation port is arranged on the rear cabinet door of the switch cabinet body; There is an electric inspection window fixed at the observation port; the electric inspection window includes an electric inspection window, tempered glass, and a lock. There is a tempered glass chute on the side, the tempered glass is inserted into the tempered glass chute, the tempered glass closes the window, the left end of the tempered glass is fixedly connected with the first hasp, and the left end of the electric test window is fixedly connected with the second hasp. The first hasp and the second hasp are locked together by a lock.

The electro-inspection form is made up of a panel, an inner slot plate and a bottom plate, and windows are arranged in the middle of the front of the panel and the bottom plate, and the inner slot plate is U-shaped, and the inner slot plate is located between the panel and the bottom plate; the panel, the inner slot plate , There are screw mounting holes on the bottom plate.

The beneficial effect of the utility model is: adopt the above structure, open the lock, slide the toughened glass to the right, the window is opened, and the electric test can be performed directly; compared with the cabinet door after opening, the window is smaller and the safety is better. The utility model retains the function of the observation window, which can be unlocked and pushed open during the electric test, and can be closed afterwards, which is more convenient. Adopt tempered glass, with explosion-proof function.
