Description

Technical Field

[0001] This utility model relates to the field of thyristor technology, specifically to a thyristor switching switch. Background Technology

[0002] Thyristor switching is a device specifically designed for dynamic and rapid compensation of power capacitors. It can achieve zero-voltage contact and zero-current disconnection, preventing inrush current. It can also compensate for inrush current, thus giving thyristor switching a function that cannot be replaced by contactors and composite switches.

[0003] In practical use, most existing thyristor switching switches are composed of multiple boards welded together. However, when the thyristor or other components are damaged, it requires a lot of time for staff to disassemble the boards, which affects the maintenance efficiency of the equipment. At the same time, the heat dissipation performance of the switch is not high, and the internal temperature will be too high after long-term use, which will cause damage to the internal circuit. Utility Model Content

[0004] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows:

[0005] A thyristor switching switch includes a mounting bracket, a thyristor switch fixedly mounted on the upper end of the mounting bracket, a mounting plate movably mounted on the front end of the thyristor switch, disassembly and assembly mechanisms on both sides of the front end of the thyristor switch, and heat dissipation mechanisms symmetrically provided at both ends of the thyristor switch.

[0006] The disassembly and assembly mechanism includes a socket, which is located at the four corners of the front end of the thyristor switch. A through hole is provided on both the upper and lower surfaces of the front end of the thyristor switch. A support frame is symmetrically fixed on both sides of the front end of the thyristor switch. A slide rod is slidably installed at both ends of the support frame. A horizontal plate is fixed on the top of the slide rod. A base plate is fixed on the bottom of the slide rod. Fixed rods are symmetrically fixed on both sides of the lower end of the base plate. A spring is sleeved on the lower end of the slide rod. Insert plates are symmetrically fixed at the four corners of the rear end of the mounting plate. A through hole is provided in the middle of the insert plate.

[0007] Preferably, the through hole is connected to the socket, and the two ends of the spring are fixedly connected to the opposite surfaces of the base plate and the upright.

[0008] Preferably, the insert plate matches the socket and is movably installed, and the fixed rod is slidably installed through the interior of through hole one and through hole two.

[0009] Preferably, the heat dissipation mechanism includes a side frame, one end of which is fixedly connected to the left and right ends of the thyristor switch. A crossbeam is fixedly provided inside one side of the side frame, and a cooling fan is rotatably installed in the middle of the crossbeam. A mounting groove is provided on one front side of the side frame, and an end plate is movably installed inside the mounting groove. A filter screen is fixedly provided at the rear end of the end plate. A perforated plate is fixedly provided at the other internal end of the side frame. Damping shafts are symmetrically fixedly installed on the upper and lower sides of the front end of the side frame. A clamping plate is rotatably installed on the outside of the damping shaft.

[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] This utility model provides a thyristor switching switch. Through a disassembly and assembly mechanism, after the insert plate on the mounting plate is inserted into the socket on the thyristor switch, the elastic effect of the spring pushes the base plate downwards, allowing the base plate to push the fixed rod through through hole one and into through hole two on the insert plate, thus fixing the mounting plate. Conversely, the fixed rod separates from through holes one and two, allowing the insert plate to be removed from the socket, thereby completing the disassembly of the mounting plate. The mounting plate facilitates disassembly and assembly, enabling timely disassembly and maintenance when the thyristor or internal components are damaged, thereby improving the performance of the thyristor switch.

[0016] This utility model provides a thyristor switching switch. Through a heat dissipation mechanism, a rotating cooling fan draws the heat generated inside the thyristor switch to the side frame via a flow channel, and then dissipates the heat out of the side frame, thereby achieving a heat dissipation effect and improving air circulation efficiency. A filter screen can filter dust from the outside air. The end plate is fixed by a snap-fit ​​on the snap-fit ​​plate and a snap-fit ​​on the end plate, thereby improving the stability of the filter screen during operation. Attached Figure Description

[0023] The present invention will be further described in detail below with reference to embodiments:

[0024] like Figures 1-5 As shown, this utility model provides a thyristor switching switch, including a mounting bracket 1. A thyristor switch 2 is fixedly mounted on the upper end of the mounting bracket 1. A mounting plate 3 is movably mounted on the front end of the thyristor switch 2. Disassembly and assembly mechanisms 4 are provided on both sides of the front end of the thyristor switch 2. Heat dissipation mechanisms 5 are symmetrically provided at both ends of the thyristor switch 2.

[0025] Multiple sets of flow grooves 6 are opened through the middle of both ends of the thyristor switch 2. The front and rear ends of both ends of the thyristor switch 2 are symmetrically provided with slots 7, and the slots 7 are slidably engaged with blocks 8.

[0026] The inside of the flow channel 6 is equipped with a dustproof net. The flow channel 6 is connected to the inside of the side frame 51. The slot 7 and the block 8 are both cross-shaped. The bottom end of the block 8 is fixedly installed to one end of the side frame 51.

[0027] In this design, the two ends of the thyristor switching switch can be disassembled through the side frame 51 by means of the card block 8 and the card slot 7. After the side frame 51 is disassembled, the flow groove 6 can be exposed. The flow groove 6 can circulate with the outside air, so that it can also achieve heat dissipation. At the same time, the dustproof net installed in the flow groove 6 can filter the dust in the outside air.

[0028] like Figure 3 As shown, the disassembly and assembly mechanism 4 includes a socket 41, which is located at the four corners of the front end of the thyristor switch 2. The upper and lower surfaces of the front end of the thyristor switch 2 are provided with through holes 42. The two sides of the front end of the thyristor switch 2 are symmetrically fixed with uprights 43. The two ends of the uprights 43 are slidably mounted with slide rods 44. The top of the slide rods 44 is fixed with a horizontal plate 45. The bottom of the slide rods 44 is fixed with a base plate 46. The two sides of the lower end of the base plate 46 are symmetrically fixed with fixed rods 47. The lower end of the slide rods 44 is sleeved with a spring 48. The four corners of the rear end of the mounting plate 3 are symmetrically fixed with insert plates 49. The middle of the insert plate 49 is provided with a through hole 410.

[0029] The through hole 42 is connected to the socket 41, and the two ends of the spring 48 are fixedly connected to the opposite surfaces of the base plate 46 and the upright 43, respectively.

[0030] The insert plate 49 matches the socket 41 and is movably installed. The fixed rod 47 is slidably installed through the interior of the through hole 42 and the through hole 410.

[0031] In this solution, when the thyristor experiences performance degradation due to prolonged operation or internal components are damaged due to overload, technicians can quickly disassemble the mounting plate 3 for timely repair or replacement. Compared with the traditional fixing method, this significantly shortens equipment downtime and effectively improves the overall performance and reliability of the thyristor switch 2.

[0032] like Figures 4-5 As shown, the heat dissipation mechanism 5 includes a side frame 51. One end of the side frame 51 is fixedly connected to the left and right ends of the thyristor switch 2. A crossbeam 52 is fixedly installed inside one side of the side frame 51. A cooling fan 53 is rotatably installed in the middle of the crossbeam 52. A mounting groove 54 is opened on one side of the front end of the side frame 51. An end plate 55 is movably installed inside the mounting groove 54. A filter screen 56 is fixedly installed at the rear end of the end plate 55. A perforated plate 57 is fixedly installed at the other end of the side frame 51. Damping shafts 58 are symmetrically fixedly installed on the upper and lower sides of the front end of the side frame 51. A clamping plate 59 is rotatably installed on the outside of the damping shaft 58. A clamping post 510 is symmetrically fixedly installed on the upper and lower ends of the end plate 55.

[0033] The filter screen 56 is slidably installed inside the side frame 51, and the surface of the perforated plate 57 has several perforated grooves.

[0034] The top of the card plate 59 has a slot that engages with the card post 510 and is movably connected.

[0035] In this design, the end plate 55 can be firmly fixed to the side frame 51 by precisely engaging the latches on the plate 59 and the posts 510. This engagement method is not only easy to operate, but also provides strong fixing force, ensuring that the filter 56 remains stable under the airflow impact generated by the high-speed operation of the cooling fan 53, without loosening or shifting. After separating the plate 59 from the posts 510, the end plate 55 can be pulled outward to easily remove the filter 56 from the side frame 51, thus facilitating the cleaning of the filter 56. The perforated plate 57 allows foreign objects to enter the side frame 51, while the perforated grooves on the perforated plate 57 facilitate air circulation.

[0036] The working principle of this thyristor switching device will be explained in detail below.

[0037] like Figures 1-5 As shown, when the thyristor switching switch needs to dissipate heat, the cooling fan 53 can be turned on to rotate. The rotating fan 53 draws the heat generated inside the thyristor switch 2 into the side frame 51 through the flow channel 6, and then dissipates it out of the side frame 51, thus achieving air circulation and heat dissipation. When the thyristor switch 2 is damaged and needs maintenance, the horizontal plate 45 can be pulled, causing the sliding rod 44 to slide outwards. The sliding rod 44 then drives the base plate 46 and the fixed rod 47 to move synchronously, causing the fixed rod 47 to engage with the through hole 42 and... When the second through hole 410 is separated, the restriction on the plug plate 49 can be released. Then, the mounting plate 3 is pulled outward to separate the plug plate 49 from the socket 41, thus completing the disassembly of the mounting plate 3. This makes it easier to open the thyristor switch 2 and facilitate its inspection and maintenance. During installation, the plug plate 49 can be inserted into the socket 41. Then, under the elastic action of the spring 48, the base plate 46 and the slide rod 44 can be pushed down. The base plate 46 drives the fixed rod 47 to move synchronously, so that the fixed rod 47 can pass through the first through hole 42 and directly insert into the second through hole 410 in the middle of the plug plate 49. This fixes the plug plate 49 and completes the stable installation of the mounting plate 3.

[0038] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the protection scope of the present invention.
