[0002] With the comprehensive transformation and development of power transmission, distribution and transformation, switchgears have increased significantly in various places. Switchgears are located at the next level below the substation in the power system. They are power facilities that supply high-voltage electricity to surrounding power users. They are not only the most basic unit at the bottom of the distribution network, but also one of the key links in the transmission of electricity from high voltage to low voltage.

[0003] The outdoor high-voltage switchgear is installed outdoors. It is mainly used to provide protection and operation platform for the ring network switch cabinet in the outdoor high-voltage switchgear. Its main function is to prevent water, dust and small animals from entering, so as to ensure the reliable operation of the electrical equipment inside the box.

[0023] The principles and features of the present invention are described below in conjunction with the accompanying drawings. The examples given are only used to explain the present invention and are not used to limit the scope of the present invention.

[0024] As described in the background technology, since the high-voltage switchgear is installed outdoors, when workers need to perform maintenance on the high-voltage switchgear on rainy days, it is necessary to shield the outside rainwater from entering the high-voltage switchgear to reduce safety hazards during maintenance. For this reason, this embodiment provides an outdoor high-voltage switchgear that is easy to maintain.

[0025] See also Figures 1 to 5 This embodiment proposes an outdoor high-voltage switchgear that is easy to maintain, including a switch box 1, a rain shielding mechanism 2 is arranged above the switch box 1, and the rain shielding mechanism 2 includes a connecting block 201 fixedly connected to the switch box 1.

The opening and closing box 1 and the connection block 201 are both made of cold-rolled steel plates, and the surfaces are electroplated and painted.

[0027] The bottom surface of the switch box 1 is fixedly connected with a support block 6, which can support the high-voltage switch, so that a certain space is reserved between the high-voltage switch and the ground to reduce the entry of external moisture into the high-voltage switch. The inner wall of the connecting block 201 is provided with a plurality of hoisting holes 7, through which the high-voltage switch can be conveniently hoisted.

[0028] Four fixing rods 8 are fixedly connected to the upper surface of the connecting block 201. Two solar panels 9 are arranged above the connecting block 201. The fixing rods 8 are fixedly connected to the solar panels 9. The fixing rods 8 provide fixed support for the solar panels 9. The solar panels 9 can convert solar energy into electrical energy and store it for subsequent use, which is energy-saving and environmentally friendly.

[0029] The upper surface of the connecting block 201 is fixedly connected to the rotating motor 10, and the output shaft end of the rotating motor 10 is fixedly connected to the animal repellent 11, see Figure 1 It can be seen that a protective cover is installed on the top of the animal repeller 11 to protect the animal repeller 11.

[0030] The animal repeller 11 can drive away wild cats, wild dogs, wolves, deer, weasels, wild boars, etc. by ultrasonic repeller, thereby preventing animals from moving around the high-voltage switchgear and affecting or damaging the operation of the high-voltage switchgear. Starting the rotating motor 10 can drive the animal repeller 11 to rotate, thereby providing all-round repeller protection for the high-voltage switchgear.

[0031] A servo motor 202 and two telescopic rods 208 are installed on the inner wall of the connecting block 201. The two output shaft ends of the servo motor 202 are fixedly connected to threaded rods 203. The two threaded rods 203 are rotatably connected to the connecting block 201. The outer surface of each threaded rod 203 is threadedly connected to a screw block 204. The two screw blocks 204 are slidably connected to the connecting block 201.

[0032] The servo motor 202 and the telescopic rod 208 are installed in the inner wall of the connecting block 201. After the servo motor 202 is started, it can drive the two threaded rods 203 to rotate synchronously in forward and reverse directions. After the threaded rods 203 rotate, they can drive the screw blocks 204 thereon to slide along the inner wall of the connecting block 201, and the two screw blocks 204 are close to or away from each other.

[0033] Two bearings 12 are embedded in the inner wall of the connecting block 201, and the inner rings of the two bearings 12 are fixedly connected to the outer surfaces of the two threaded rods 203 respectively. The bearings 12 can make the threaded rods 203 more stable when rotating, avoiding the threaded rods 203 from getting stuck and swinging during use.

[0034] The inner walls of the two screw blocks 204 are hinged with hinge blocks 205 through pins, the inner wall of the connecting block 201 is slidably connected with a slider 206, the two hinge blocks 205 are hinged with the slider 206 through pins, the two telescopic rods 208 are fixedly connected to the slider 206, the back of the slider 206 is fixedly connected with a tarpaulin 207, and the tarpaulin 207 is fixedly connected to the connecting block 201.

[0035] After the screw block 204 moves, it can drive the hinge block 205 to move, the hinge block 205 drives the slider 206 to move, and the slider 206 drives the tarpaulin 207 to move, so that the tarpaulin 207 gradually unfolds to shield the front side of the high-voltage switch station, forming a rain shelter area, preventing outside rainwater from entering the high-voltage switch station, reducing safety hazards during maintenance by staff, and improving safety performance.

[0036] The tarpaulin 207 is made of a transparent waterproof material, so that people can observe the situation outside the tarpaulin 207 while being shielded by the tarpaulin 207. The telescopic rod 208 can guide and support the slider 206, making the slider 206 more stable during the forward and backward movement.

[0037] Four box doors 3 are installed on the inner wall of the opening and closing box 1. Door locks are installed on the box doors 3 to lock the opening and closing box 1 to prevent people other than staff from opening it at will and causing safety accidents.

[0038] A warning sign 4 is fixedly connected to the front of each box door 3, which can remind people to prevent danger and avoid accidents. A heat dissipation hole 5 is opened on the inner wall of each box door 3, which can increase the air circulation of the switch box 1 and improve the heat dissipation and cooling effect of the high-voltage switch.

[0039] A controller 13 is installed on the front of the switch box 1, the servo motor 202 is electrically connected to the controller 13, and the rotary motor 10 is electrically connected to the controller 13.

After the threaded rod 203 rotates, it can drive the screw block 204 thereon to slide along the inner wall of the connecting block 201, so that the two screw blocks 204 are close to each other. After the screw block 204 moves, it can drive the hinge block 205 to move, and the hinge block 205 drives the slider 206 to move. The slider 206 drives the tarpaulin 207 to move, so that the tarpaulin 207 gradually unfolds to cover the front side of the switch box 1, forming a The telescopic rod 208 can guide and support the slider 206 to make the slider 206 more stable during the forward and backward movement. After the maintenance is completed, the staff can control the servo motor 202 to reverse, and then retract the rain cover 207.
