[0002] High-voltage ring main units are designed to improve power supply reliability, allowing users to obtain power from two directions. They typically connect the power grid into a ring, a power supply method known simply as ring network power supply. In AC 10kV distribution systems such as ports and high-rise buildings, where the load capacity is not large, the high-voltage circuit is usually controlled by load switches or vacuum contactors and equipped with high-voltage fuses for protection. They are widely used in distribution stations and prefabricated substations in load centers such as urban residential areas, high-rise buildings, large public buildings, and factories.
[0003] High-voltage ring network switchgear is often used in outdoor settings. When it is necessary to maintain or operate the switchgear, if it rains, rainwater can easily enter the switch cabinet and cause damage to the ring network switchgear, affecting the maintenance progress. Since ring network switchgear does not have a rain shelter, maintenance work cannot be carried out in bad weather, causing inconvenience to maintenance personnel. Utility Model Content

[0022] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.
[0023] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.
[0024] Example 1: As Figures 1-6 As shown, this utility model provides a high-voltage ring network switchgear, including a cabinet 1, a rain cover 2 on the top of the cabinet 1, a winding chamber 3 fixed on the top of the cabinet 1, a winding assembly 4 on the winding chamber 3, a round rod 5 fixed to one end of the rain cover 2, three mounting sleeves 6 fixed at equal intervals on the surface of the round rod 5, and a mounting assembly 7 on the cabinet 1; the winding assembly 4 includes a winding roller 401 rotatably connected to the inner walls of both sides of the winding chamber 3 by bearings, a discharge port 402 opened on the front of the winding chamber 3, and the other end of the rain cover 2 passing through the discharge port 402 and fixed on the winding roller 401.
[0025] The overall effect of embodiment 1 is that the rain cover 2 is stored in the winding chamber 3, and the winding assembly 4 can wind and unwind the rain cover 2, thus facilitating the winding, storage and use of the rain cover 2. When the rain cover 2 is not in use, it can be protected, reducing the risk of damage to the rain cover 2. The installation assembly 7 can support the rain cover 2 to form a rain shelter space, thus facilitating personnel to carry out maintenance work on the high-voltage ring network switch equipment in rainy weather. The round rod 5 is used to support and flatten the end of the rain cover 2.
[0026] Example 2: As Figures 1-6As shown, a rotating rod 403 is installed inside the discharge port 402. Both ends of the rotating rod 403 are rotatably connected to the inner walls of the two sides of the winding chamber 3 via bearings. The rotating rod 403 is located above the rainproof cloth 2, and the surface of the rotating rod 403 is in contact with the surface of the rainproof cloth 2. A housing 404 is fixed to one side wall of the winding chamber 3. A reduction motor 405 is fixed to the bottom inner wall of the housing 404. One end of the winding roller 401 passes through one side wall of the winding chamber 3 and is fixedly connected to the output shaft of the reduction motor 405. The mounting assembly 7 includes a storage cabinet 701 fixed to one side of the cabinet 1. The front of the storage cabinet 701 is hinged to a lockable cabinet door 702. Three elastic claws 703 are fixed at equal intervals on one surface of the storage cabinet 701. Each of the three elastic claws 703 tightly clamps a support cylinder 704. A support rod 705 is slidably connected inside. The top end of the support rod 705 slides through the top of the support cylinder 704 and is fixed with a protrusion. A connecting sleeve 706 is fixed on the top surface of the support cylinder 704. A screw 707 is threadedly connected inside the connecting sleeve 706. A rubber pad 708 is rotatably connected to one end of the screw 707 through a bearing. The rubber pads 708 slide in the corresponding support cylinder 704 and are in close contact with the surface of the adjacent support rod 705. A limit block 709 is fixed at the bottom of the support rod 705. A limit groove 710 adapted to the limit block 709 is opened on the inner wall of the support cylinder 704. The limit block 709 is slidably connected in the corresponding limit groove 710. The bottom end of the support cylinder 704 is relatively sharp. An auxiliary plate is fixedly fitted on the surface of the support cylinder 704.
[0027] The overall effect of Embodiment 2 is as follows: the rotating rod 403 in the discharge port 402 is used to pull the rain cover 2 and make the rain cover 2 move in and out of the discharge port 402 very smoothly; the protrusion is used to cooperate with the binding rope to firmly bind the top of the support rod 705 to the mounting sleeve 6; the limiting block 709 and the limiting groove 710 are used to limit the support rod 705 so that the support rod 705 can only extend and retract within the support cylinder 704 and cannot rotate, thereby ensuring the stable positioning of the rain cover 2; the auxiliary plate makes it convenient for personnel to apply force to the support cylinder 704, and with the relatively sharp bottom end, the bottom end of the support cylinder 704 can be easily inserted into the ground at a suitable position to pull the rain cover 2.
[0028] Working principle: When the outdoor ring main switchgear needs maintenance, the personnel first use the support cylinder 704 and support rod 705 to support the rain cover 2, start the reduction motor 405, and the output shaft of the reduction motor 405 slowly rotates, driving the winding roller 401 to slowly rotate, loosening the winding of the rain cover 2. At this time, the personnel hold one end of the fixed round rod 5 of the rain cover 2, and the rain cover 2 can slowly extend downwards until the rain cover 2 is fully extended out of the winding chamber 3. Then the reduction motor 405 can stop working. Then the personnel use the key to open the lockable cabinet door 702, take out the binding rope stored in the storage cabinet 701, and remove the support cylinder 704 from the elastic claw 703. Then, the personnel need to adjust the length of the support cylinder 704 and support rod 705 according to the actual situation. The personnel rotate the screw 707. With the cooperation of the internal thread of the connecting sleeve 706, the rotating screw 707 can move outwards together, which can drive the rubber pad 708 at the other end of the screw 707 to move outwards together. The rubber pad 708 slowly detaches from the tight contact with the support rod 705 until the support rod 705 can slide inside the support cylinder 704. Then, the screw 707 is rotated again after the support rod 705 extends to a suitable length. The screw 707 rotates in the opposite direction, which causes the screw 707 to move the rubber pad 708 in the opposite direction, gradually making contact with the surface of the support rod 705 inside the support cylinder 704. The rubber pad 708 makes tight contact with the surface of the support rod 705 again, thus restricting the position of the support rod 705. Finally, the personnel use a rope and an installation sleeve 6 on the round rod 5 to tie and fix the top of the support rod 705 to the installation sleeve 6. After tying, the bottom end of the support cylinder 704 is inserted into the ground in a suitable position. The remaining two support cylinders 704 and support rods 705 are installed to the installation sleeves 6 in the same way. After installation, the rain cover 2 can be opened to facilitate maintenance work under the rain cover 2.
[0029] The wiring diagram of the geared motor 405 and the control device of the high-voltage ring network switchgear in this utility model is common knowledge in the field. Its working principle is a well-known technology. The appropriate model is selected according to actual use. Therefore, the control method and wiring layout of the geared motor 405 will not be explained in detail. In summary, the problems raised in the background above are solved.
[0030] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the present utility model.
