Detailed ways

As shown in FIG. 1 to FIG. 3 , the cross-arm pole-integrated insulating shielding cover for non-power-off operation of the distribution network disclosed in this embodiment includes a cross-arm support shield body 1 and a pole shield body 2 .

The cross-arm support shielding body 1 is a U-shaped body made of nylon, which is arranged horizontally. The width of the notch between the arms on both sides corresponds to the height of the cross-arm support, and the width of the side walls corresponds to the width of the cross-arm support.

The pole shielding body 2 includes two C-shaped bodies 21 and a connecting lug plate 22, both of which are made of nylon. The connecting lug plate 22 has a U-shaped groove along the width direction at the middle position in the length direction, and the two ends of the length direction are respectively fixed. at the axial center plane of the outer walls of the arc sections of the two C-shaped bodies 21 .

Both sides of the opening of the C-shaped body 21 are folded with everted edges.

There is a handle on the outer side of the connecting ear plate 22 corresponding to the U-shaped groove.

The cross arm bracket shielding body 1 is inserted into the space between the two C-shaped bodies 21 and the U-shaped groove of the connecting lug plate 22, and the outer wall of the plug-in part is bonded to the end face of the C-shaped body 21 and the U-shaped groove of the connecting lug plate 22. glued together.

In this embodiment, the shielding body of the cross arm support and the shielding body of the pole are made of nylon material, so that the whole shielding cover is light in weight and has good insulation performance.

Both the cross-arm support shield and the pole cover are open-type structures. After being made of nylon material, the opening can have a certain elastic deformation. Therefore, the size of the notch of the cross-arm support cover can be adjusted to the height of the cross-arm support. The dimensions are equal, so that the diameter of the C-shaped body of the pole shield is slightly smaller than the outer diameter of the pole, so that the shield will not fall off easily after installation. Both sides of the opening of the C-shaped body are provided with everted folds, which not only facilitates the clamping and installation of the pole shielding body, but also enhances the clamping force.

During installation, the operator wears insulating gloves and then buckles the handle, aligns the cover of the cross-arm support with the cross-arm support, and aligns the shield of the pole with the pole, and then clamps it on the cross-arm support and the pole at the same time. Make the cross-arm support and the poles on the upper and lower sides of the cross-arm support shielded at the same time.

The length of the C-shaped body of the pole shielding body can be determined according to actual needs.

After the shield is installed, the operator can perform live operation on the closed side of the shield.

The cross arm support shield body and the pole cover body of the shielding cover have an integrated structure, and the transverse insertion groove of the cross arm support cover body and the vertical clamping groove of the pole cover body are arranged in a cross shape, so the cross arm support shield When the body shields the cross-arm support, the pole shielding body can simultaneously shield the electric poles on the upper and lower sides of the cross-arm support, so that the insulation shielding is in place. There is a plug-in installation method between the transverse insertion slot of the cross-arm support shield and the cross-arm, and the clamp installation between the pole shield and the pole, and the cross-arm support can be plugged and electrically connected at the same time during installation. For the clamping of the pole, when dismantling after the work is completed, just hold the handle and pull out the pole shielding body and the cross arm shielding body at the same time. No fasteners are required for installation and disassembly, and the operation is simple and convenient.
