Description

Technical Field

[0001] The utility model relates to the technical field of reactive power generators, in particular to a wall-mounted static reactive power generator. Background Art

[0002] Static VAR generator is called high-voltage dynamic VAR compensation generator, or static synchronous compensator. It connects the self-commutated bridge circuit to the power grid through a reactor or directly in parallel, adjusts the phase and amplitude of the output voltage on the AC side of the bridge circuit, or directly controls the AC side current, so that the circuit absorbs or emits reactive power that meets the requirements, and achieves the purpose of dynamic reactive power compensation. Reactive compensation devices should be installed in all places where low-voltage transformers are installed and next to large electrical equipment, especially in factories, mines, enterprises, and residential areas with low power factor.

[0003] The patent document with application number CN201720261930.1 discloses a wall-mounted static reactive generator, including a mainframe housing, a mounting back plate welded on the back of the mainframe housing, a mounting hole drilled on the top of the mounting back plate, and a supporting base plate vertically connected to the bottom; a liquid crystal display is inlaid on the upper front end of the mainframe housing, a function button is inlaid on the right side of the liquid crystal display, and an interface panel is inlaid on the lower housing of the liquid crystal display; an integrated circuit board is fixedly installed inside the mainframe housing, an isolation transformer and a DSP processor are welded on the integrated circuit board, and a self-commutated bridge rectifier circuit is connected to the output end of the isolation transformer; an FPGA controller is connected to the communication interface end of the DSP processor, a signal conditioner is connected to the parallel input end of the FPGA controller, and a phase-locked loop is connected to the phase control end of the signal conditioner; and a photoelectric isolation driver is connected to the signal output end of the DSP processor. The utility model improves the control accuracy and response speed of reactive current and adds remote monitoring function.

[0004] Although the remote monitoring function can be used to monitor the generator in real time during use, the generator is inconvenient to maintain when it needs maintenance, and the connecting and installing parts are relatively simple, making the installation unstable. For example, when the generator needs to be maintained, all the bolts on the upper end of the generator need to be removed before the generator can be removed from the fixed position. At the same time, the installation of the generator through bolts makes the installation and placement of the generator relatively simple, and the generator may fall and be damaged due to unstable installation, affecting subsequent use. Utility Model Content

[0005] The utility model discloses a wall-mounted static reactive generator, which aims to solve the technical problems that although a remote monitoring function can be used to monitor the generator in real time during use, the generator is inconvenient to maintain and the connecting and installing parts are relatively simple, making the installation unreliable.

[0006] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0007] A wall-mounted static reactive generator comprises a placement table and a mounting plate, wherein a generator body is fixedly placed on the upper end of the placement table; a heat dissipation device, wherein the heat dissipation device is arranged in the middle of the placement table, and the heat dissipation device is used to dissipate heat for the generator body; a clamping device, wherein the clamping device is arranged at the upper end of the placement table, and the clamping device is used to limit and clamp the generator body; an adjustment device, wherein the adjustment device is arranged at the rear end of the clamping device, and the adjustment device comprises a connecting block fixedly mounted on the upper and lower parts of the right end of the mounting plate on the right side, wherein the connecting block is rotatably connected to the connecting plate through a damping shaft, and a mounting rod is fixedly mounted in the middle of the rear end of the connecting plate, and the adjustment device is used to adjust the angle of the placement table and the mounting plate; a locking device, wherein the locking device is arranged on the left side of the mounting plate and the connecting plate, and the locking device is used to limit the connection between the mounting plate and the connecting plate.

[0008] By setting up a heat dissipation device, the generator body can be cooled by blowing air to reduce the heat of the generator body, so that the performance of the generator body will not be reduced during long-term use. The clamping device allows a generator body of any size to be placed on the placement table and clamped in a limited position, so that the placement table has a wider range of use. The adjustment device can adjust the angle of the generator body within a certain range, making the use of the generator body more convenient. By setting up a locking device, the generator body can be limited in a fixed position.

[0009] In a preferred solution, the heat dissipation device includes a mounting groove opened in the middle of the placement table, a mounting frame is fixedly installed at the lower end of the mounting groove, a driver is fixedly installed in the middle of the mounting frame, and fan blades are arranged at the upper end of the driver.

[0010] By arranging fan blades to blow air to the upper end of the placement table, the temperature of the generator body will not be too high during use, thereby ensuring the performance of the generator body and increasing the service life of the generator body.

[0011] In a preferred embodiment, the clamping device includes a mounting plate integrally connected to the upper left and right ends of the rear portion of the placing table, springs are fixedly provided at the upper and lower ends of the front end of the mounting plate, a clamping block is fixedly provided at one end of the spring away from the mounting plate, and a resistance rubber pad is fixedly bonded to the rear surface of the clamping block.

[0012] By setting the spring and the card block, the generator body can be slightly limited and locked on the placement table to prevent the generator body from falling due to unstable placement. The resistance rubber pad increases the friction between the contact surface of the card block and the generator body, so that the card block will not slip off easily.

[0013] As can be seen from the above, it includes a placement table, on the upper end of which the generator body is fixedly placed; a heat dissipation device, which is arranged in the middle of the placement table, and is used to dissipate heat for the generator body; a clamping device, which is arranged at the upper end of the placement table, and is used to limit and clamp the generator body; an adjustment device, which is arranged at the rear end of the clamping device, and includes a connecting block fixedly mounted on the upper and lower parts of the right end of the mounting plate on the right side, and the connecting block is rotatably connected to the connecting plate through a damping shaft, and a mounting rod is fixedly mounted in the middle of the rear end of the connecting plate, and the adjustment device is used to adjust the angle of the placement table and the mounting plate; a locking device, which is arranged on the left side of the mounting plate and the connecting plate, and is used to limit the connection between the mounting plate and the connecting plate. The utility model provides a wall-mounted static reactive generator with the following improvements and advantages:

[0014] First, the clamping device allows a generator body of any size to be placed on the placement table and clamped in a limited position, so that the placement table has a wider range of uses. The fan blades blow air to the upper end of the placement table so that the temperature of the generator body will not be too high during use, thereby ensuring the performance of the generator body and increasing the service life of the generator body.

[0015] Second: the mounting plate can be rotated by the damping shaft to drive the generator body to move and adjust the angle position. The generator body can be slightly limited on the placement table by setting the spring and the card block to prevent the generator body from falling due to unstable placement. The resistance rubber pad increases the friction between the contact surface of the card block and the generator body, so that the card block will not slip off easily.

[0023] The utility model discloses a wall-mounted static reactive generator which is mainly used in scenarios where, although a remote monitoring function can be used to monitor the generator in real time during use, the generator is inconvenient to maintain and the components for connection and installation are relatively simple, making the installation unreliable.

[0024] Reference Figure 1 , Figure 2 , Figure 3 and Figure 4A wall-mounted static reactive generator comprises a placement table 1 and a mounting plate 7, wherein a generator body 2 is fixedly placed on the upper end of the placement table 1; a heat dissipation device, which is arranged in the middle of the placement table 1; a clamping device, which is arranged at the upper end of the placement table 1; an adjusting device, which is arranged at the rear end of the clamping device; and a locking device, which is arranged on the left side of the clamping device and the adjusting device. It includes a placement table 1, on the upper end of which a generator body 2 is fixedly placed; a heat dissipation device, which is arranged in the middle of the placement table 1 and is used to dissipate heat for the generator body 2; a clamping device, which is arranged at the upper end of the placement table 1 and is used to limit and clamp the generator body 2; an adjusting device, which is arranged at the rear end of the clamping device, and includes a connecting block 11 fixedly mounted on the upper and lower parts of the right end of the right mounting plate 7, the connecting block 11 is rotatably connected to a connecting plate 13 through a damping shaft 12, a mounting rod 14 is fixedly mounted in the middle of the rear end of the connecting plate 13, and the adjusting device is used to adjust the angle of the placement table 1 and the mounting plate 7; a locking device, which is arranged on the left side of the mounting plate 7 and the connecting plate 13, and is used to limit the connection between the mounting plate 7 and the connecting plate 13.

[0025] The heat dissipation device can blow air to dissipate the heat of the generator body 2, thereby reducing the heat of the generator body 2 and ensuring that the performance of the generator body 2 will not be reduced during long-term use. The clamping device can place a generator body 2 of any size on the placement table 1 and be clamped in a limited position, making the placement table 1 more widely used. The adjustment device can adjust the angle of the generator body 2 within a certain range, making the use of the generator body 2 more convenient. The locking device can be set so that the generator body 2 can be limited in a fixed position.

[0026] Reference Figure 1 and Figure 2 In a preferred embodiment, the heat dissipation device includes a mounting groove 3 opened in the middle of the placement table 1, a mounting frame 4 is fixedly installed at the lower end of the mounting groove 3, a driver 5 is fixedly installed in the middle of the mounting frame 4, and a fan blade 6 is arranged at the upper end of the driver 5.

[0027] The mounting frame 4 and the driver 5 are mounted at the lower end of the mounting slot 3 opened in the middle of the placement table 1, the fan blades 6 are connected to the driver 5, and the fan blades 6 are driven to rotate by the driver 5, so as to dissipate heat for the generator body 2 placed on the upper end of the placement table 1.

[0028] Reference Figure 4 In a preferred embodiment, the clamping device includes a mounting plate 7 integrally connected to the upper left and right ends of the rear portion of the placing table 1, springs 8 are fixedly provided at the upper and lower ends of the front end of the mounting plate 7, a clamping block 9 is fixedly provided at one end of the spring 8 away from the mounting plate 7, and a resistance rubber pad 10 is fixedly bonded to the rear surface of the clamping block 9.

[0029] While placing the generator body 2 on the placement table 1, stretch the block 9 and clamp it on the surface of the generator body 2. The elastic force of the spring 8 retracts the block 9 backwards, so that the block 9 limits the generator body 2 to a certain extent. The resistance rubber pad 10 on the inner surface of the block 9 increases the friction between the block 9 and the generator body 2, preventing the block 9 from easily falling off the generator body 2.

[0030] Reference Figure 3 and Figure 4 In a preferred embodiment, lock buckles 16 are fixedly installed at the upper and lower ends of the left side of the mounting plate 7, and lock blocks 15 are fixedly installed at the upper and lower ends of the left side of the connecting plate 13.

[0031] When the generator body 2 does not need to be adjusted, the lock block 15 can be buckled into the lock buckle 16 to connect and limit the mounting plate 7 and the connecting plate 13, so that the mounting plate 7 is fixed.

[0032] Working principle: When in use, the generator body 2 is installed and placed on the placement table 1, and the upper part of the generator body 2 is clamped and limited by the clamping device, so that the placement of the generator body 2 is more stable, and the removal and maintenance of the generator body 2 is also more convenient. When the generator body 2 needs to be maintained, the placement table 1 and the mounting plate 7 are rotated by adjusting the damping shaft 12 in the device, so that the generator body 2 is adjusted to a certain angle, which is convenient for staff to observe and repair. In normal placement, the placement table 1 can also be locked by buckling the lock block 15 into the lock buckle 16, so that the generator body 2 is stably placed. During use, the heat dissipation device is used to dissipate heat from the generator body 2, so that the use effect of the generator body 2 is better.

The replacement can be a replacement of part of the structure, device, method step, or a complete technical solution. Equivalent replacement or change based on the technical solution of the utility model and its utility model concept should be included in the protection scope of the utility model.
