Background technique

In the power system, when carrying out live operation on devices with many live parts in electric cabinets such as power distribution cabinets and switch cabinets, it is easy to cause short circuit or electric shock due to accidental touching of live parts, and there are certain safety risks. For example, the staff who install the meter and connect the electricity, when replacing the metering device on the live low-voltage distribution panel of the substation, because there are many live parts on the switchboard, there is a possibility of personal electric shock when the staff operates, which poses a certain safety risk.

The patent application number is 201020650315.8 discloses a bracket-type insulating baffle, the bottom of the insulating baffle is respectively provided with a support leg on the left and right sides, and the left and right sides of the lower part of the warning surface of the insulating baffle are respectively provided with a handle. However, this insulating baffle is integrated, and it is inconvenient to carry and store during use.

Contents of the invention

Detailed ways

The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

As shown in Figure 1, the combined insulation isolation device includes a base 3 and at least two insulating inserts 4, the bottom of the base 3 is provided with a left support foot 1 and a right support foot 2, and the upper end of the base 3 is provided with a base slot 5 , the upper end of each insulating board 4 is provided with a board slot 6, the first insulating board is inserted into the base slot 5, the second insulating board is inserted into the first board, and the rest are sequentially inserted. At least one U-shaped connecting seat 7 is fixed on one side of at least one insulating board 4, and the U-shaped connecting seat 7 is provided with a fastening screw 8, as shown in FIG. 2 . The number of insulating boards is 4. The materials used for the insulating board 4 and the base 3 are resin materials.

When in use, the present invention is placed in front of the workers and the charging device, so that the workers and the charging device can be isolated to ensure the personal safety of the workers. The quantity of insulating boards 4 can be adjusted according to the height of the parts to be inspected.

If it is necessary to check and maintain the lower part of the electric cabinet where the live device is placed, the base 3 can be used, and the U-shaped connecting seat 7 can be inserted and fastened to an appropriate position on the side plate of the electric cabinet using the fastening screw 8, as shown in Figure 2.
