Description

A GW4-126 isolating switch knife gate sealing cover

technical field

The utility model relates to the technical field of a dust-proof device for a knife gate of a GW4-126 isolating switch.

Background technique

The switch of the substation under cold and hot standby state is in the open state for a long time. Since the isolating switch is in the cold and hot standby state for a long time, the knife gate is easy to accumulate pollution due to poor dust prevention effect. Once the above knife switch is put into operation, Due to the serious pollution, poor contact of the knife gate often leads to burning. The burning of the knife gate requires a power outage to deal with it. The maintenance cost is high, and at the same time, it causes load loss.

Utility model content

The technical problem to be solved by the utility model is to provide a GW4-126 isolating switch knife gate sealing cover which is easy to use, dustproof and rainproof.

In order to solve the above technical problems, the technical solution adopted by the utility model is: a GW4-126 isolating switch knife gate sealing cover, including a box body and a movable panel, and one end surface of the box body is provided with a The movable panel is plugged and connected with the box body, the top of the box body is provided with a handle, and the box body and the movable panel are made of insulating material.

Further, the movable panel is provided with a U-shaped opening, and the top of the movable panel is provided with a hanging hole.

Further, the material of the box body and the movable panel is plastic.

The beneficial effects produced by adopting the above technical scheme are: the utility model effectively prevents the GW4-126 isolating switch knife gate from absorbing dust, is easy to install and disassemble, saves manpower and material resources for replacing the knife gate, and improves the safety and reliability of the power grid and equipment. This device is installed when the isolating switch is in cold and hot standby, and it is removed during normal operation. The installation and removal are simple and convenient, and the dust-proof effect on the knife gate is excellent. It does not affect the normal operation of the equipment and reduces the serious pollution caused by the knife gate. In the event of a defect, the maintenance efficiency and maintenance level are improved to ensure that the maintenance work of the isolating switch is completed safely and efficiently.

Description of drawings

Fig. 1 is the structural representation of the utility model;

Among them, 1 box body, 2 movable panels, 3 handles, 4 hanging holes, and 5 grooves.

Detailed ways

Below in conjunction with accompanying drawing and specific embodiment, the utility model is described in further detail.

As shown in Figure 1, the utility model is a GW4-126 isolating switch knife gate sealing cover, including a box body 1 and a movable panel 2, and one end surface of the box body 1 is provided with a Groove 5, the movable panel 2 is plugged and connected with the box body 1, the top of the box body 1 is provided with a handle 3, the box body 1 and the movable panel 2 are insulating materials; the movable panel 2 is provided with a U-shaped Opening, the top of the movable panel 2 is provided with a hanging hole 4; the material of the box body 1 and the movable panel 2 is plastic.

The operator hooks the handle part of the device through the insulating operating rod, and sets the device on the knife gate of the GW4-126 isolating switch; then pulls down the movable panel through the insulating operating rod, and seals the knife gate of the GW4-126 isolating switch in all directions . When it is necessary to replace the knife gate of the GW4-126 isolating switch, use the insulating operating rod to lift the lifting hole hooking the movable panel to the movable panel, and then remove the device from the knife gate of the GW4-126 isolating switch through the insulating operating rod. This device is installed when the isolating switch is in cold and hot standby, and it is removed during normal operation. The installation and removal are simple and convenient, and the dust-proof effect on the knife gate is excellent. It does not affect the normal operation of the equipment and reduces the serious pollution caused by the knife gate. In the event of a defect, the maintenance efficiency and maintenance level are improved to ensure that the maintenance work of the isolating switch is completed safely and efficiently.

The utility model is made of transparent insulating plastic, has light weight, good insulation and convenient installation. When the isolating switch is in the cold and hot standby state, the device is installed at the gate of the knife gate, and it is removed when switching or cutting is required. Only one person needs to use the insulating pull rod for installation and removal. The device is small and light, has no effect on the normal operation of the equipment, and has an excellent dust-proof effect. In view of the current situation of the isolating switch for cold and hot standby in substations, the use of this device can reduce equipment damage events caused by serious pollution at the knife gate, and it is worth promoting.

The utility model aims at the size of the knife gate of GW4-126 isolating switch 180*180*200, and the designed and manufactured size is 300*300*330. It is convenient to be installed on the knife gate of GW4-126 isolation switch, which is convenient for disassembly and installation.
