[0002] The switch cabinet is an electrical equipment. The external line of the switch cabinet first enters the main control switch inside the cabinet, and then enters the branch control switch. Each branch is set according to its needs. According to different voltage levels, it can be divided into high-voltage switch cabinet, medium-voltage switch cabinet and low-voltage switch cabinet, etc., high-voltage disconnectors and grounding switches, high-voltage load switches, high-voltage automatic reclosing and sectionalizers, high-voltage operating mechanisms, high-voltage explosion-proof distribution devices and high-voltage switch cabinets.

[0003] When there is a fault in the equipment in the switch cabinet, it needs to be repaired and maintained. During this process, the cabinet door needs to be kept open. When people pass by, there is a risk of electric shock. Protective devices need to be installed. The traditional protective structure enclosure is not convenient to fix and cannot be used with cabinets of different sizes. Therefore, we propose a protective device for high-voltage switch cabinets. Utility Model Content

By arranging a first insulating rod, a third insulating rod and a second insulating rod with adjustable widths to form a frame structure, an adsorption plate at the end of the first insulating rod can be used to adsorb and cling to the surfaces of cabinets or cabinet doors on both sides of the switch cabinet during inspection and maintenance, so that the structure can be conveniently and quickly enclosed at the front end of the switch cabinet to achieve the purpose of protection. The width can be adjusted to adapt to switch cabinets of different sizes for safe protection, thereby solving the problems raised in the background technology.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a protective device for a high-voltage switch cabinet, comprising a first insulating rod, a second insulating rod and a third insulating rod, wherein the first insulating rod and the second insulating rod are both bent into an L-shape, and the ends of the first insulating rod and the second insulating rod are close to each other; a slide groove is provided inside the place where the first insulating rod and the second insulating rod are close to each other, and the slide groove is connected to the through-holes provided at the ends of the first insulating rod and the second insulating rod, and the two ends of the third insulating rod can be slidably inserted into the slide grooves of the first insulating rod and the second insulating rod through the through-holes, and the ends of the first insulating rod and the second insulating rod are both fixed with adsorption plates, and magnets are embedded and fixed inside the adsorption plates; the outer surfaces of the first insulating rod and the second insulating rod at the through-holes are connected with locking bolts by means of a screw connection, and the ends of the locking bolts penetrate into the through-holes and abut against the surface of the third insulating rod, and the bottoms of the first insulating rod and the second insulating rod are both supported with a plurality of insulating support rods.

Finally, the structure is enclosed in the outer circle of the switch cabinet by means of adsorption of the magnet inside the adsorption plate, thereby achieving the purpose of safety protection.

[0015] Compared with the prior art, the technical solution of this application has the following beneficial effects:

[0016] 1. The technical solution of the present application is to set a first insulating rod, a third insulating rod and a second insulating rod with adjustable width to form a frame structure.

[0023] See also Figure 1-3 The utility model provides a technical solution: a protective device for a high-voltage switch cabinet, comprising a first insulating rod 1, a second insulating rod 2 and a third insulating rod 3, the first insulating rod 1 and the second insulating rod 2 are both bent into an L shape, and the first insulating rod 1 and the second insulating rod 2 have the same size, and the ends of the first insulating rod 1 and the second insulating rod 2 are close to each other.

[0024] A slide groove 7 is provided inside the part where the first insulating rod 1 and the second insulating rod 2 are close to each other, and a through hole 71 is provided at the end of the first insulating rod 1 and the second insulating rod 2 on the side of the slide groove 7. The slide groove 7 is connected to the through hole 71. The diameter of the third insulating rod 3 is smaller than the inner diameter of the through hole 71, so that the two ends of the third insulating rod 3 are inserted into the slide groove 7 of the first insulating rod 1 and the second insulating rod 2 through the through hole 71. Slide blocks 31 are fixed to the ends of both ends of the insulating rods. The diameter of the slide block 31 is smaller than the diameter of the slide groove 7, so that the slide block 31 can be slidably placed in the slide groove 7. The diameter of the slide block 31 is larger than the inner diameter of the through hole 71, which can prevent the slide block 31 from sliding out of the slide hole, thereby limiting the third insulating rod 3 from being pulled out of the slide groove 7. The sliding changes the length of the third insulating rod 3 leaking out of the outside, which can change the width of the frame structure surrounded by the first insulating rod 1, the third insulating rod 3 and the second insulating rod 2, so that it can be adapted to high-voltage switch cabinets of different widths.

[0025] The outer surfaces of the first insulating rod 1 and the second insulating rod 2 at the through-hole 71 are connected with a locking bolt 6 by means of a screw connection. When the width of the frame structure formed by the first insulating rod 1, the third insulating rod 3 and the second insulating rod 2 is determined, the locking bolt 6 is tightened so that its end passes through the through-hole 71 and contacts the surface of the third insulating rod 3 to lock the width. The bottoms of the first insulating rod 1 and the second insulating rod 2 are supported by a plurality of insulating support rods 5, which are evenly supported at the bottoms of the first insulating rod 1 and the second insulating rod 2, and the insulating support rods 5 are supported on the ground by the support plates 51 at their bottoms to achieve stable support for the structure.

[0026] An adsorption plate 4 is fixed to the end of the first insulating rod 1 and the second insulating rod 2. A magnet 41 is embedded and fixed inside the adsorption plate 4, so that the adsorption plate 4 is close to the cabinet door surface or the cabinet surface on both sides of the switch cabinet to be inspected and maintained. The magnet 41 can be adsorbed with the cabinet or the cabinet door. A rubber pad 42 is fixed to the surface of the adsorption plate 4 in a fitting manner, so that the adsorption plate 4 is in contact with the cabinet or the cabinet door surface through the rubber pad 42, so that the first insulating rod 1, the third insulating rod 3 and the second insulating rod 2 form a frame structure to quickly enclose the front end of the cabinet, thereby achieving the purpose of safety protection.

[0027] During use, after the cabinet door of the high-voltage switch cabinet under maintenance is opened, the adsorption plates 4 at the ends of the first insulating rod 1 and the second insulating rod 2 are attached to the surface of the adjacent switch cabinet or the opened cabinet door. Under the adsorption effect of the magnet 41, the adsorption plates 4 are tightly pressed against the surface of the cabinet body or the cabinet door through the rubber pad 42, so that the frame structure surrounded by the first insulating rod 1, the third insulating rod 3 and the second insulating rod 2 surrounds the front end of the switch cabinet during maintenance and is stably supported by the insulating support rod 5 and the support plate 51, thereby achieving the purpose of isolation protection, preventing personnel from approaching the switch cabinet, reducing the risk of electric shock, and targeting width. When different switch cabinets are used, before adsorption and fixing, the locking bolt 6 can be loosened first so that its end no longer contacts the surface of the third insulating rod 3, and the third insulating rod 3 and the slider 31 at its end can slide inside the arc groove, thereby changing the leakage length of the third insulating rod 3, so that the width of the frame structure formed by the first insulating rod 1, the third insulating rod 3 and the second insulating rod 2 is changed to be suitable for the use of the switch cabinet, and then the locking bolt 6 is tightened so that its end contacts the surface of the third insulating rod 3 again, and then the frame structure formed by the first insulating rod 1, the third insulating rod 3 and the second insulating rod 2 can be adsorbed and fixed to achieve the protection purpose.
