Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0022] See also Figure 1-4 In this embodiment, a high-voltage dynamic reactive power compensation device includes an installation cabinet 1, a heat dissipation mechanism is provided on the installation cabinet 1, and an auxiliary component is provided on the installation cabinet 1.
[0023] Embodiment 1: A heat dissipation mechanism is used, including a rain shield 2 fixedly installed on the top of the installation cabinet 1, two mesh plates 3 are fixedly installed inside the installation cabinet 1, a compensation device body 4 is arranged between the two mesh plates 3, mesh holes are evenly distributed inside the mesh plate 3, and the compensation device body 4 is installed between the two mesh plates 3 through a fixing frame, so that the heat generated by the compensation device body 4 during operation can be dissipated in time through the mesh holes.
[0024] It should be added that the compensation device body 4 is composed of parallel capacitors, series reactors, discharge coils and other structures, which helps to reduce equipment capacity, reduce power loss, improve power supply quality, and improve power transmission capacity when in use. A ventilation seat 5 is fixedly installed on the top of the installation cabinet 1, and a sealing hole is opened on the top of the installation cabinet 1. The ventilation seat 5 is fixedly connected to the installation cabinet 1 through the sealing hole, which facilitates the discharge of heat from the installation cabinet 1 through the internal structure of the ventilation seat 5, so that the internal structure of the installation cabinet 1 can operate stably.
[0025] Among them, a protective net 6 is fixedly installed inside the ventilation seat 5, a mounting frame 7 is fixedly installed inside the ventilation seat 5, an exhaust fan 8 is installed on the top of the mounting frame 7, filter nets 9 are arranged on both sides of the installation cabinet 1, a coolant tank 10 is fixedly installed on the side of the mesh plate 3 close to the inner wall of the installation cabinet 1, a coolant pipe 11 is arranged at the bottom of the coolant tank 10, and fixed blocks 12 are fixedly installed on both sides of the installation cabinet 1, an adjusting rotating rod 13 is rotatably connected to the top of the fixing block 12, and the outer side of the adjusting rotating rod 13 is threadedly connected to a movable rod 14 extending into the inner wall of the installation cabinet 1.
[0026] Among them, a limit groove is opened inside the inner wall of the installation cabinet 1, and the movable rod 14 is slidably connected to the installation cabinet 1 through the limit groove, which is convenient for limiting the movement of the movable rod 14 through the limit groove, so that the movement of the movable rod 14 remains stable, and the bottom of the movable rod 14 is fixedly installed with a plug rod 15 movably plugged into the top of the filter screen 9. A socket is opened on the top of the filter screen 9, and the plug rod 15 is movably plugged into the filter screen 9 through the socket, which is convenient for fixing the filter screen 9 through the plug rod 15, thereby ensuring its working stability and facilitating its subsequent disassembly, cleaning or replacement.
[0027] Embodiment 2: The auxiliary components include a mounting plate 16 fixedly mounted on both sides of the mounting cabinet 1. Floor pads 17 are fixedly mounted on the bottom of the mounting plate 16 and the mounting cabinet 1. There are multiple floor pads 17, which are evenly distributed on the bottom of the mounting cabinet 1 and the mounting plate 16. The mounting plate 16 and the mounting cabinet 1 can be easily padded by the floor pads 17 to avoid direct contact with the ground, thereby helping to protect the mounting cabinet 1 from moisture. A warning sign 18 is fixedly mounted on the top of the mounting plate 16 to serve as a warning to prevent unauthorized personnel from approaching the mounting cabinet 1 and causing safety hazards.
[0028] It should be noted that the high-voltage dynamic reactive power compensation device, through the use of a heat dissipation mechanism, cooperates with the various structures on the installation cabinet 1, and uses the ventilation seat 5 to discharge the heat generated by the compensation device body 4 during operation, so that the internal temperature of the installation cabinet 1 remains normal, and blocks external dust and impurities through the filter 9, thereby improving the operating stability and reliability of the compensation device body 4. At the same time, with the cooperation of auxiliary components, the warning sign 18 is used to mark the area around the installation cabinet 1 to avoid safety accidents caused by unrelated personnel approaching, thereby helping to improve the safety performance of the compensation device body 4 when in use.
[0029] The working principle of the above embodiment is:
[0030] When the high-voltage dynamic reactive power compensation device is in use, before the operation of the compensation device body 4, coolant is injected into the coolant tank 10 and passed into the coolant pipe 11. The heat generated when the compensation device body 4 is in operation is dissipated to the inside of the installation cabinet 1 through the mesh plate 3. At this time, the exhaust fan 8 inside the ventilation seat 5 is started to discharge the heat from the top of the installation cabinet 1. While the heat is being discharged, the outside air enters the installation cabinet 1 through the filter 9. After being used for a period of time, the filter 9 drives the plug 15 at the bottom of the movable rod 14 to separate from the filter 9 by rotating the adjustment lever 13, so that the staff can remove the filter 9 for cleaning or replacement. At the same time, the warning sign 18 is set to prevent irrelevant personnel from approaching the installation cabinet 1, thereby improving the safety and stability of the compensation device body 4 during operation.
