Embodiment

[0017] When replacing the on-pole load switch (model: Schneider RL27-LBS-SF6) in live work, use the switch combination insulation shielding cover for insulation shielding, continue to ensure insulation, and ensure that the overlapping part of the insulation cover is not less than 15 cm.

[0018] The 10 kV load switch combined insulating shield is composed of the main insulating shield 1, the left and right opening insulating shield 3, the hard insulating flat plate 4, and the mother and child adhesive strip 5. The hard insulating flat plate 4 is fixed on the main insulating shield Supported on the cover 1, the main insulating shielding cover 1 is connected with the insulating shielding covers 3 with left and right side openings through the mother and child adhesive strips 5.

[0019] The main insulating shield 1 is made of rubber insulating material, and switch terminal holes 2 are left on both sides according to the actual size of the switch, and are opened at the lower end of...

Abstract

The invention relates to a 10 kV load switch combined insulation shielding cover suitable for insulating and shielding switching when replacing a 10 kV load switch with electricity. Composed of insulating flat boards (4) and parent-child adhesive strips (5), the switch combination insulation shielding cover of the present invention replaces the original cumbersome use of insulating blankets to shield the load switch. The working efficiency is greatly improved, and the left and right insulation shielding parts are added, which can effectively shield the terminal openings on both sides of the main shielding cover, increase the creepage ratio distance, and enhance the insulation effect. The invention has the advantages of simple structure, convenient use and high safety factor, and is suitable for large-scale popularization and use of electric power systems.

Description

technical field [0001] The invention relates to a safety appliance for an insulating shield, in particular to a combined insulating shield for a 10 kilovolt load switch which is suitable for insulating and shielding switching when a 10 kilovolt load switch is replaced with electricity. Background technique [0002] According to the "Technical Guidelines for Live Work on Distribution Lines", when replacing a 10 kV pole-mounted load switch with live electricity, the live body, grounding body, switch and accessories must be insulated and shielded. Due to the relatively large volume and irregular shape of the load switch, multiple insulating blankets are needed to completely cover the load switch insulation, and it is also very troublesome to fix the insulating blanket, which is cumbersome, laborious and time-consuming to work. Contents of the invention [0003] The present invention improves on the problems existing in the above-mentioned prior art, and changes the original u...
