Description

Technical Field

[0001] This utility model relates to the field of safety equipment technology, specifically a safe and waterproof high-voltage ring main unit. Background Technology

[0002] High-voltage ring main units (RMMs) are key equipment in power distribution systems, primarily used for the control and protection of power lines at voltage levels of 10-35kV. Their core functions include power distribution, load switching, and short-circuit current interruption. In substations and industrial and mining power supply systems, RMMs must meet the requirements for all-weather outdoor installation.

[0003] Current mainstream ring main units adopt a metal shell structure, achieving basic waterproofing through rubber sealing strips at the cabinet door seams. To accommodate heat dissipation requirements, ventilation holes are typically provided at the bottom of the enclosure, and dust filters are added. Some high-end models use silicone sealant to treat the seams of the mounting covers. Installation methods mostly involve fixing with anchor bolts or suspending with brackets.

[0004] There are three main problems with the existing technology:

[0005] (1) The contradiction between waterproof performance and equipment lifespan: rubber sealing strips are prone to plastic deformation when the temperature difference exceeds 40℃, leading to water leakage;

[0006] (2) Defects in heat dissipation structure design: Traditional dustproof nets are prone to condensation backflow when the air humidity is too high;

[0007] (3) The joint treatment of the cover is not thorough, and the probability of rainwater seeping into the bolt installation holes increases under heavy rain conditions, resulting in poor waterproofing effect. Utility Model Content

[0008] (a) Technical problems to be solved

[0009] The purpose of this invention is to overcome the shortcomings of the existing technology and provide a safe and waterproof high-voltage ring main unit.

[0010] (II) Technical Solution

[0011] To achieve the above objectives, the present invention provides the following technical solution: a safe and waterproof high-voltage ring main unit, including a mounting cover, the mounting cover (1) being fitted to the inner wall of the ring main unit; the front of the mounting cover is provided with a mounting cavity, an electrical component assembly is installed inside the mounting cavity, a heat dissipation base hole is provided on the inner bottom wall of the mounting cavity, a heat dissipation mechanism is provided inside the heat dissipation base hole, two mutually symmetrical mounting mechanisms are provided on the outside of the mounting cover, and a sealing mechanism is provided at the front of the mounting cover.

[0012] Furthermore, the sealing mechanism includes a sealing frame, the back of which is fixedly connected to the front of the mounting cover, a first strong magnetic frame is fixedly connected to the rear side of the inner wall of the sealing frame, and a first gasket is fixedly connected to the front of the sealing frame.

[0013] Furthermore, a second strong magnetic frame is adsorbed and connected to the front of the first strong magnetic frame, a sealed cabinet door is fixedly connected to the front of the second strong magnetic frame, and a second gasket is fixedly connected to the back of the sealed cabinet door.

[0014] Furthermore, the heat dissipation mechanism includes a mounting plate, the outer surface of which is fixedly connected to the inner wall of the heat dissipation base hole, and the upper surface of the mounting plate is provided with two sets of second through holes arranged at equal intervals, and the upper surface of the mounting plate is provided with a third through hole.

[0015] Furthermore, check valves are installed inside both sets of the second through holes, a cylinder is fixedly connected to the inner wall of the third through hole, and an exhaust fan is installed on the upper surface of the mounting plate, with the input end of the exhaust fan connected to the top of the cylinder.

[0016] Furthermore, the mounting mechanism includes a mounting strip and two symmetrical screws. The side of the mounting strip near the mounting cover is fixedly connected to the outer surface of the mounting cover. The front of the mounting strip has two symmetrical fourth through holes.

[0017] Furthermore, a pad is fixedly connected to the back of the mounting strip, and two symmetrical fifth through holes are opened on the front of the pad. The output ends of the two screws pass through the fourth and fifth through holes in sequence and extend to the rear of the pad.

[0018] (III) Beneficial Effects:

[0019] Compared with existing technologies, this new waterproof power failure safety protector has the following advantages:

[0020] I. This utility model, through the cooperation of the mounting cover, mounting cavity, and sealing mechanism, controls the second strong magnetic frame to penetrate the first gasket and insert into the interior of the sealing frame, while simultaneously causing the first and second strong magnetic frames to be attracted and connected, thereby making the first and second gaskets fit tightly together. Thus, the electrical component assembly can be sealed in the sealed mounting cover formed by the mounting cover, mounting cavity, and sealing mechanism, achieving the purpose of convenient waterproofing of this device.

[0021] II. This utility model, through the design of a heat dissipation mechanism, draws external air into the mounting cavity when the internal temperature is too high. A check valve then expels the air from inside the cavity, creating an air circulation system that effectively cools the high-temperature gas. In use, the second strong magnetic frame penetrates the first gasket and inserts into the sealing frame, simultaneously attracting and connecting them. This ensures a tight seal between the first and second gaskets, sealing the electrical component assembly within the sealed mounting cover, mounting cavity, and sealing mechanism. This provides a convenient and waterproof solution. Attached Figure Description

[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0030] like Figure 1-6 As shown, this utility model provides a technical solution: a safe and waterproof high-voltage ring main unit, including a mounting cover 1, which is fitted to the inner wall of the ring main unit, and a mounting cavity 2 is opened on the front of the mounting cover 1. An electrical component group 3 is installed inside the mounting cavity 2. The electrical component group 3 consists of conventional electrical components in the ring main unit, including at least multiple switches, high-voltage circuit breakers, and high-voltage fuses. A heat dissipation base hole 4 is opened on the inner bottom wall of the mounting cavity 2, and a heat dissipation mechanism 5 is installed inside the heat dissipation base hole 4.

[0031] The heat dissipation mechanism 5 includes a mounting plate 501. The outer surface of the mounting plate 501 is fixedly connected to the inner wall of the heat dissipation base hole 4. The upper surface of the mounting plate 501 is provided with two sets of equidistant second through holes 502 and a third through hole 503. Check valves 504 are installed inside both sets of second through holes 502. A cylinder 506 is fixedly connected to the inner wall of the third through hole 503. An exhaust fan 505 is installed on the upper surface of the mounting plate 501. The input end of the exhaust fan 505 is connected to the top end of the cylinder 506.

[0032] The electrical component group 3 is installed on the rear side wall of the mounting cavity 2. The exhaust fan 505 is a common electrical device in the prior art, and this application will not elaborate on its model or internal structure. It can also be replaced by other power sources. The check valve 504 is prior art and will not be elaborated on. The check valve 504 can effectively prevent water from entering the interior of the mounting cavity 2, but can discharge the air inside the mounting cavity 2. When the temperature inside the mounting cavity 2 is too high, the exhaust fan 505 is started, which can draw the outside air into the interior of the mounting cavity 2 and discharge the gas inside the mounting cavity 2 through the check valve 504, so that the inside of the mounting cavity 2 and the outside air are circulated, thereby discharging the high temperature gas inside the mounting cavity 2 and achieving the purpose of efficient cooling of this device.

[0033] The external mounting cover 1 has two mutually symmetrical mounting mechanisms 6.

[0034] The mounting mechanism 6 includes a mounting strip 601 and two symmetrical screws 605. The side of the mounting strip 601 near the mounting cover 1 is fixedly connected to the outer surface of the mounting cover 1. The front of the mounting strip 601 has two symmetrical fourth through holes 602. The back of the mounting strip 601 is fixedly connected to a pad 603. The front of the pad 603 has two symmetrical fifth through holes 604. The output ends of the two screws 605 pass through the fourth through holes 602 and the fifth through holes 604 in sequence and extend to the rear of the pad 603.

[0035] The material of the pad 603 is preferably rubber. When installing this device, first place the device in the installation position, and control the two sets of symmetrical screws 605 to pass through the fourth through hole 602 and the fifth through hole 604 in sequence, and thread them into the reserved installation hole of the device, thus achieving the purpose of quick installation of the device.

[0036] A sealing mechanism 7 is provided in front of the mounting cover 1.

[0037] The sealing mechanism 7 includes a sealing frame 701, the back of which is fixedly connected to the front of the mounting cover 1. A first strong magnetic frame 702 is fixedly connected to the rear side of the inner wall of the sealing frame 701. A first gasket 703 is fixedly connected to the front of the sealing frame 701. A second strong magnetic frame 706 is adsorbed and connected to the front of the first strong magnetic frame 702. A sealing cabinet door 704 is fixedly connected to the front of the second strong magnetic frame 706. A second gasket 705 is fixedly connected to the back of the sealing cabinet door 704.

[0038] The first strong magnetic frame 702 and the second strong magnetic frame 706 are preferably made of strong magnets. The length and width of the second strong magnetic frame 706 are the same as those of the first strong magnetic frame 702. When the second strong magnetic frame 706 and the first strong magnetic frame 702 are attracted and connected, the first gasket 703 and the second gasket 705 are tightly attached. The second gasket 705 and the first gasket 703 are preferably made of rubber. The second strong magnetic frame 706 is controlled to pass through the first gasket 703 and be inserted into the interior of the sealing frame 701. At the same time, the first strong magnetic frame 702 and the second strong magnetic frame 706 are attracted and connected, thereby making the first gasket 703 and the second gasket 705 tightly attached. Thus, the electrical component assembly 3 can be sealed in the sealed mounting cover formed by the mounting cover 1, the mounting cavity 2, and the sealing mechanism 7, achieving the purpose of convenient waterproofing of this device.

[0039] Working Principle: During installation, the device is first placed in the mounting position within the ring main unit. Two sets of symmetrical screws 605 are then sequentially inserted through the fourth through hole 602 and the fifth through hole 604, and threaded into the pre-drilled mounting holes, achieving rapid installation. In use, the second strong magnetic frame 706 penetrates the first gasket 703 and inserts into the sealing frame 701. Simultaneously, the first strong magnetic frame 702 and the second strong magnetic frame 706 are attracted and connected, thereby causing the first gasket 703 to connect with the second strong magnetic frame 701. The two gaskets 705 fit tightly together, thus sealing the electrical component assembly 3 within the sealed mounting cover formed by the mounting cover 1, the mounting cavity 2, and the sealing mechanism 7. This achieves the purpose of convenient waterproofing of the device. When the temperature inside the mounting cavity 2 is too high, the exhaust fan 505 is started to draw external air into the mounting cavity 2 and discharges the gas inside the mounting cavity 2 through the check valve 504, so that the inside of the mounting cavity 2 and the outside form an air circulation, thereby expelling the high-temperature gas inside the mounting cavity 2 and achieving the purpose of efficient cooling of the device.
