Description

Technical Field

[0001] The utility model relates to the technical field of low-voltage capacitor cabinets, in particular to a low-voltage capacitor cabinet. Background Art

[0002] Low-voltage capacitor cabinet is a kind of power compensation equipment, which is mainly used to improve the power factor of the power system and improve the quality of electric energy. In the power system, due to the presence of inductive loads (such as motors, transformers, etc.), the power factor will be reduced and the loss of reactive power will increase. The low-voltage capacitor cabinet is equipped with a capacitor bank, which provides reactive power to the system through the reactive compensation of the capacitor, thereby reducing the flow of reactive current in the power grid and improving the power factor. This helps to reduce line losses, improve the transmission efficiency of the power grid, and enhance the utilization rate of power equipment. At the same time, it can stabilize the grid voltage and ensure the safe and stable operation of the power system. It is widely used in various power-using places such as factories, shopping malls, and office buildings.

[0003] For example, the Chinese patent publication number CN220233871U discloses a low-voltage capacitor cabinet, including a cabinet body, a mounting frame and a slide seat are installed inside the cabinet body, roller frames are installed on both sides of the mounting frame, a roller body is installed on the roller frame, a slide groove is opened on the slide seat, and the roller body is embedded in the inside of the slide groove and is slidably connected with the slide groove; the utility model can pull the mounting frame out a certain distance by applying a certain external force, and the electrical components fixed on the upper end of the mounting frame are pulled out synchronously, reducing the obstruction of the cabinet body, facilitating the inspection and maintenance of the electrical components without disassembling the electrical components, and when replacing the faulty electrical components, there is no need to reach into the cabinet body for disassembly, which facilitates the maintenance of the electrical components located at the inner end of the capacitor cabinet and reduces the difficulty of inspection and maintenance, and achieves fastening through the magnetic attraction between the first magnetic suction sheet and the second magnetic suction sheet, ensuring the stability of the mounting frame and avoiding vibration of the mounting frame.

[0004] After using this low-voltage capacitor cabinet, it was found that although the capacitor cabinet is fastened by the magnetic attraction between the first magnetic sheet and the second magnetic sheet, if the magnetic force is small, it may cause the mounting frame to be unstable. If the magnetic force is large, it may cause disassembly difficulties. The structure of the magnetic sheet is unreasonable and has low practicality. Utility Model Content

[0005] The utility model aims to provide a low-voltage capacitor cabinet to solve the problem of unreasonable structure of magnetic suction sheets.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a low-voltage capacitor cabinet, comprising a cabinet body, a first mounting frame is provided on the front side of the cabinet body, gears are rotatably connected to the inner sides of the first mounting frame, a worm is rotatably connected to the inner lower side of the first mounting frame, the worm cooperates with the gear, a second mounting frame is fixedly connected to the rear side of the first mounting frame, a rotating rod is fixedly connected to the rear side of the gear, the rotating rod is rotatably connected to the second mounting frame, a clamping block is fixedly connected to the rear side of the rotating rod, a through hole is opened on the rear side of the cabinet body, the clamping block cooperates with the through hole, and a mounting frame is fixedly connected between the second mounting frames.

[0010] Preferably, a rotating block is fixedly connected to the side surface of the worm.

[0011] Preferably, the length of the rotating rod is greater than the length of the sliding rail.

[0012] Compared with the prior art, the beneficial effects of the utility model are:

[0013] The utility model rotates the worm, the gear, the rotating rod, and the clamping block by rotating the rotating block. The clamping block remains at the rear of the cabinet and cannot pass through the through hole. The first installation frame and the second installation frame are fixed and cannot be moved. When it needs to be removed, the rotating block is rotated in the opposite direction, the worm, the gear, the rotating rod, and the clamping block are rotated in the opposite direction.

[0023] See also Figure 1-7The utility model provides a technical solution: a low-voltage capacitor cabinet, including a cabinet body 1, which is placed in a cool and dry place. A first installation frame 2 is provided on the front side of the cabinet body 1. The first installation frame 2 is hollow inside. Gears 302 are rotatably connected to the two sides of the first installation frame 2. There are two gears 302, one on the left and one on the right. A worm 301 is rotatably connected to the lower side of the first installation frame 2. The worm 301 runs through the entire first installation frame 2 and extends out of the first installation frame 2 on the right side. The worm 301 cooperates with the gear 302. The rotation of the worm 301 can make the two gears 302 rotate at the same time. A second installation frame 201 is fixedly connected to the rear side of the first installation frame 2. The second installation frame 201 has two and are parallel to each other. A rotating rod 4 is fixedly connected to the rear side of the gear 302. The rotating rod 4 is rotatably connected to the second installation frame 201. The rotating rod 4 rotates inside the second installation frame 201. The gear 302 rotates, which can The rotating rod 4 rotates, and the rotating rods 4 on both sides rotate synchronously. The rear side of the rotating rod 4 is fixedly connected with a clamping block 401. When the rotating rod 4 rotates, the clamping block 401 rotates accordingly. A through hole 402 is opened on the rear side of the cabinet 1, and the clamping block 401 cooperates with the through hole 402. During installation, the first installation frame 2 and the second installation frame 201 move backwards, and the clamping block 401 moves backwards and passes through the through hole 402. After passing through, the rotating rod 4 rotates, and the clamping block 401 rotates accordingly. The clamping block 401 remains at the rear of the cabinet 1 and cannot pass through the through hole 402. The first installation frame 2 and the second installation frame 201 are fixed and cannot move. The worm 301 has a self-locking feature. As long as the worm 301 is not rotated, the gear 302 cannot rotate, the rotating rod 4 cannot rotate, and the clamping block 401 cannot rotate. The structure is more stable. A mounting frame 203 is fixedly connected between the second installation frames 201, and related equipment is placed on the upper surface of the mounting frame 203.
