The utility model is used for direct electric inspection of 10 kV switchgear.

Description

10 kV switchgear that can be tested directly

technical field

The utility model relates to a 10 kilovolt switch cabinet.

Background technique

At present, the high-voltage switchgear, that is, the ground wire of the 10 kV switchgear line or the ground knife of the combined line cannot be directly tested, but indirectly, and the indirect power test is judged by the power indicator light on the switchgear panel. electricity, which does not meet the safety requirements of the State Grid Corporation of China. In the existing operating switchgear, due to the locking relationship, the rear net door can only be opened by closing the ground knife, and the electricity cannot be tested directly. The dangerous point is that the power indicator light is damaged, and the line reverses the power supply, which will cause the charged grounding knife switch to affect safe operation of the power system.

Utility model content

The utility model solves the problem that the existing operating switchgear cannot be tested directly, and the dangerous point is that the power indicator light is damaged, and the line reverses the power supply, which will cause the electrified and grounded knife switch to affect the safe operation of the power system, and further provides A 10 kV switchgear that can be tested directly.

The technical scheme adopted by the utility model to solve the above technical problems is: the 10 kV switchgear that can be directly inspected in the utility model includes a switchgear main body, and the switchgear also includes an electrical inspection window, and the switchgear body is processed There is an electric inspection window, which is located at the lower part of the main body of the switch cabinet. The electric inspection window is rectangular, the length of the electric inspection window is 35-50cm, and the height of the electric inspection window is 20-35cm. The electric inspection window of the main body and the electric inspection window cover on the electric inspection window, one side of the electric inspection window is rotatably connected with the main body of the switch cabinet, and the other side of the electric inspection window is locked by five anti-locks.

The beneficial effects of the utility model are:

The rear net door of the 10 kV switchgear of the utility model is provided with an electric inspection window and an electric inspection window. Due to the locking relationship with the existing operating switch cabinet, the rear net door can only be opened by closing the ground knife, and the electric inspection cannot be directly carried out. For example, during the electrical inspection, the electrical inspection window can be opened by opening the five-proof lock, which avoids the dangerous point when the power indicator is damaged and the line reverses the power supply, causing the charged and grounding knife switch to ensure the safe operation of the power system.

Detailed ways

Specific Embodiment 1: As shown in Figure 1, the 10 kV switchgear that can be directly inspected in this embodiment includes a switchgear main body 1, and the switchgear also includes an electrical inspection window 2, and the rear of the switchgear body 1 The electric inspection window 1-1 is processed on the net door, and the electric inspection window 1-1 is located at the lower part of the main body 1 of the switch cabinet. The electric inspection window 1-1 is rectangular, and the length L of the electric inspection window 1-1 is 35-50cm , the height H of the electric test window 1-1 is 20~35cm, the electric test window 2 is installed at the electric test window 1-1 of the main body 1 of the switchgear and the electric test window 2 is covered on the electric test window 1-1, the electric test One side of the window 2 is rotatably connected with the main body 1 of the switch cabinet, and the other side of the electroscope window 2 is locked by five anti-locks.

Described five anti-locks are prior art.

Embodiment 2: As shown in FIG. 1 , the length L of the electrometry window 1 - 1 in this embodiment is 40 cm. Such design leaves enough space for electrical inspection. Other components and connections are the same as those in the first embodiment.

Embodiment 3: As shown in FIG. 1 , the height H of the electro-detection window 1 - 1 in this embodiment is 30 cm. Such design leaves enough space for electrical inspection. Other compositions and connections are the same as those in Embodiment 1 or 2.

Embodiment 4: In this embodiment, the middle part of the electroscope window 2 is a glass window. With such a design, the inside of the switchgear can be observed without opening the electrodetection window 2 . Other components and connections are the same as those in the third embodiment.
