Description

A high-voltage ring network cabinet

technical field

The utility model belongs to the field of high-voltage electrical equipment, in particular to a high-voltage ring network cabinet.

Background technique

The high-voltage ring network cabinet is the basic equipment for the high-voltage ring network power supply. The high-voltage ring network cabinet has high-voltage electricity inside. In order to ensure the safety of the staff, the design idea is that the cabinet can only be opened after the power is off, that is, the load switch is opened. body back door. Therefore, the opening of the back door of the high-voltage ring network cabinet in the prior art requires the staff to have good professionalism, but if the staff is slightly negligent, serious safety accidents will occur.

Utility model content

The purpose of this utility model is to provide a high-voltage ring network cabinet. The utility model has a simple structure. A hanging rod is set on the load switch, and the card set on the back door of the cabinet body is used to realize the opening and closing of the back door and the opening and closing of the load switch. Gate interlock control.

The technical scheme that the utility model adopts is as follows:

A high-voltage ring network cabinet, including a load switch in the cabinet and a cabinet back door, the end of the load switch is fixedly connected to the fixed end of the L-shaped hanging rod, and a There is a gap on the card; when the load switch is closed, the free end of the L-shaped hanging rod is matched with the gap; when the load switch is opened, the free end of the L-shaped hanging rod is separated from the card.

Preferably, a shaft is fixed at the end of the load switch, the shaft is coaxially connected with the fixed end of the L-shaped hanging rod, and the shaft is made of insulating material.

Preferably, the L-shaped hanging rod and the card are made of iron material, and the surfaces of the L-shaped hanging rod and the card are covered with insulating materials.

When the power supply of the high-voltage ring network cabinet is required, the staff inserts the operating handle into the operating hole of the load switch of the high-voltage ring network cabinet, turns the load switch, and makes the load switch close. The free end of the L-shaped hanging rod is hung in the gap of the card on the cabinet back door, and the cabinet back door cannot be opened.

On the contrary, when the power supply of the high-voltage ring network cabinet is not needed, the staff turns the load switch through the operating handle to make the load switch open. The free end is separated from the card on the back door of the cabinet, and the back door of the cabinet can be opened.

The shaft, L-shaped hanging rod and card are all covered with insulating material, which has good insulation and improves the operating safety of the staff.

Compared with the prior art, the utility model has the following advantages: the structure is simple, the L-shaped hanging rod is set on the load switch, and the card set on the back door is used to realize the opening and closing of the back door and the opening and closing of the load switch. control.

Detailed ways

In order to make the purpose, technical solution and advantages of the utility model clearer, the utility model will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the utility model, and are not intended to limit the utility model.

As shown in Figure 1-4, a high-voltage ring network cabinet includes a load switch 1 inside the cabinet and a rear door 2 of the cabinet. The end of the load switch 1 is fixed with a shaft 4, and the shaft 4 is fixed to the L-shaped hanging rod 5. The ends are coaxially connected, and a card 3 is provided at the same level as the back door 2 of the cabinet body and the L-shaped hanging rod 5, and a gap 6 is provided on the card 3; when the load switch 1 is closed, the free end of the L-shaped hanging rod 5 and the The gap 6 cooperates, and the free end of the L-shaped hanging rod 5 is separated from the card 3 when the load switch 1 is opened.

The L-shaped hanging rod 5 and the card 3 are made of iron material, and the surface of the L-shaped hanging rod 5 and the card 3 is coated with an insulating material, and the shaft 4 is made of an insulating material.

When the power supply of the high-voltage ring network cabinet is required, the staff inserts the operating handle into the operating hole of the load switch of the high-voltage ring network cabinet, turns the load switch 1, and makes the load switch 1 close. At the same time, the load switch 1 drives the L-shaped hanging rod during the rotation process. 5 rotates, make the free end of L-shaped hanging rod 5 hang in the gap 6 of the card 3 on the cabinet back door 2, and the cabinet back door 2 can't be opened.

On the contrary, when the power supply of the high-voltage ring network cabinet is not needed, the staff turns the load switch 1 through the operating handle to make the load switch 1 open. The free end of type hanging rod 5 is separated from the card 3 on the cabinet back door 2, and the cabinet back door 2 can be opened.

The shaft 4, the L-shaped hanging rod 5 and the card 3 are all covered with insulating material, which has good insulation and improves the operating safety of the staff.
