Technical Field

[0001] The utility model relates to the technical field of switches, in particular to a modular thyristor switching switch. Background Art

[0002] The modular thyristor switching switch is an advanced power electronic device that combines thyristor (SCR) technology and modular design, aiming to provide efficient and reliable power compensation solutions. The design of this switch aims to solve the limitations of traditional power electronic devices in dealing with complex power grid environments and frequent operations. The modular thyristor switching switch has high versatility, can adapt to different application scenarios and requirements, and has a compact overall structure, beautiful appearance, and effectively saves space. The thyristor switching switch integrates an air-cooling module, which is beneficial to heat dissipation, improves the stability and service life of the device. The application of thyristor technology enables the switch to have the characteristic of rapid response and is suitable for application occasions with rapid load changes. The thyristor switching switch is suitable for the rapid input and cut-off of 400V low-voltage capacitors, can complete the ideal reactive power compensation function, and can be used in conjunction with controllers of other manufacturers, supporting level control signals. However, for the common modular thyristor switching switches on the market, when fixing the circuit, it is necessary to use bolts to tighten and fix laboriously, which is rather cumbersome, and the fixing effect is limited, there is a risk of pulling and detaching, and after the modular thyristor switching switch is damaged, it is necessary to disassemble it laboriously, which affects the maintenance efficiency. Summary of the Utility Model

[0003] An embodiment of the present disclosure relates to a modular thyristor switching switch. When the circuit needs to be fixed, the control member can be directly pulled up, so that it drives the moving assembly and the fixed tooth assembly to move upward together. Then, the circuit is controlled to be inserted into the inside of the slot. Then, the control member and the moving assembly are pressed downward, so that the fixed tooth assembly contacts the circuit. At the same time, the limiting plate assembly, by virtue of its own elasticity and the inclined surface, continuously presses the control member and the moving assembly downward, so that the fixed tooth assembly continuously receives force and contacts the circuit. Since the fixed tooth assembly is inclined and has a pyramid structure, it contacts the circuit in the reverse direction of the pulling direction of the circuit, improving the fixing effect on the circuit and preventing the circuit from directly detaching after being pulled.

[0004] In the first aspect of the present disclosure, a modular thyristor switching switch is provided, specifically including: a switch body; a movable component that can move freely up and down is inserted and installed on the side of the switch body. A fixed tooth component is fixed at the bottom of the movable component with a T-shaped structure. The uniformly staggered fixed tooth components are in a pyramid structure, and the fixed tooth components are inclined; an installation structure; the installation structure is fixedly installed at the bottom of the switch body. Two limiting rod structures are respectively fixed on both sides of the top of the installation structure. The upper and lower ends of the inner side of the limiting rod structure made of elastic metal are in an arc structure, and a wedge-shaped force-bearing block structure is fixed at the top of the limiting rod structure.

[0005] In at least some embodiments, two L-shaped slots are respectively opened on both sides of the switch body. The top of the slot is in an inclined structure. The limiting rod structure and the force-bearing block structure are inserted into the slot. Uniformly arranged wire slots are respectively provided on both sides of the switch body. The wire is inserted into the wire slot; Uniformly arranged top slots are respectively opened on both sides of the switch body. The top slots are above the wire slots. Both ends of the movable component are respectively in the wire slot and the top slot. A control member is fixed at the top of the movable component. The front end of the control member is in an arc structure; Uniformly arranged fixing plate components are respectively embedded and fixed on both sides of the switch body. The fixing plate components made of metal are on the side of the top of the top slot. A V-shaped limiting plate component is fixed at the front end of the fixing plate component. The outer angle of the limiting plate component made of elastic metal is in an arc structure. The bottom of the outer end of the limiting plate component is in sliding contact with the included angle position at the rear end of the control member.

[0006] In at least some embodiments, a T-shaped inner slot is penetrated and opened inside the installation structure. A limiting hole is opened on the side of the installation structure. A fixing bolt is inserted into the limiting hole; Two guiding structures for guiding are fixed outside the installation structure. A sliding plate structure is slidably installed inside the two guiding structures and can slide freely up and down inside the guiding structures; A pushing rod is respectively fixed at both ends of the sliding plate structure. The bottom end of the pushing rod is in a wedge-shaped structure. The pushing rod is attached to the side of the switch body. The inclined surface of the pushing rod is in sliding contact with the force-bearing block structure. A pressing structure is fixed on the outside of the sliding plate structure and the pushing rod.

[0007] The utility model provides a modular thyristor switching switch, which has the following beneficial effects:

[0008] When a fixed circuit is needed, the control member can be directly pulled upward, driving the moving component and the fixed tooth component to move upward together. Then, the circuit is controlled to be inserted into the inside of the slot. Next, the control member and the moving component are pressed downward, making the fixed tooth component contact the circuit. At the same time, the limiting plate component, by virtue of its own elasticity and the inclined surface, continuously presses down the control member and the moving component, enabling the fixed tooth component to continuously apply force and contact the circuit. Since the fixed tooth component is inclined and has a pyramid structure, it contacts the circuit in the direction opposite to the pulling direction, improving the fixing effect on the circuit and preventing the circuit from directly detaching after being pulled.

[0009] After the installation structure is fixed, the control switch body is connected to the installation structure, and the limiting rod structure is inserted into the inside of the card slot. When the switch body needs to be disassembled for maintenance or repair, while the switch body is fixed, the pressing structure can be directly pressed downward to displace, making the push rod slide into contact with the force-receiving block structure. Since the contact surface is an inclined structure, it controls the force-receiving block structure and the limiting rod structure to incline, releasing the connection strength with the card slot. Then, the switch body is pulled to be conveniently disassembled and removed. BRIEF DESCRIPTION OF THE DRAWINGS

[0023] Embodiment 1: Please refer to Figures 1 to 6 :

[0024] The present utility model provides a modular thyristor switching switch, including: a switch body 1; a moving assembly 106 that can move freely up and down is inserted and installed on the side of the switch body 1, driving a fixed tooth assembly 108 to move downward together. A fixed tooth assembly 108 is fixed at the bottom of the T-shaped moving assembly 106. The uniformly and staggeredly arranged fixed tooth assemblies 108 are in a pyramid structure, and the fixed tooth assemblies 108 are inclined to be used for contacting and fixing the circuit, improving the connection effect of the circuit. After the circuit is pulled, it contacts the fixed tooth assembly 108 reversely to prevent the circuit from directly detaching after being pulled; an installation structure 2; the installation structure 2 is fixedly installed at the bottom of the switch body 1. Two limiting rod structures 203 are respectively fixed at both sides of the top of the installation structure 2. The upper and lower ends of the inner side of the limiting rod structure 203 made of elastic metal are in an arc structure. A force-bearing block structure 204 with a wedge structure is fixed at the top of the limiting rod structure 203. After the push rod 207 moves downward, it slides into contact with the force-bearing block structure 204, causing the limiting rod structure 203 to tilt, facilitating the release of the fixation of the switch body 1, and enabling the switch body 1 to be conveniently pulled out for disassembly, improving the maintenance and repair efficiency.

[0025] In the embodiments of the present disclosure, such as Figure 3 And Figure 4As shown in the figure, two L-shaped slots 101 are respectively opened on both sides of the switch body 1. The top of the slot 101 is of an inclined structure. A limiting rod structure 203 and a force-receiving block structure 204 are inserted into the slot 101, so that the switch body 1 and the mounting structure 2 are firmly connected together. Insertion slots 102 are respectively arranged on both sides of the switch body 1 in a uniformly arranged manner. The circuit is inserted into the insertion slots 102, so that the circuit is squeezed and fixed inside the insertion slots 102. Top slots 103 are respectively opened on both sides of the switch body 1 in a uniformly arranged manner. The top slots 103 are located above the insertion slots 102, so that the control member 107 can freely displace inside them. Both ends of the moving assembly 106 are respectively located inside the insertion slots 102 and the top slots 103. A control member 107 is fixed at the top of the moving assembly 106. The front end of the control member 107 is of an arc structure, which facilitates pulling the moving assembly 106 to move up and down. Fixing plate assemblies 104 are respectively embedded and fixed on both sides of the switch body 1 in a uniformly arranged manner. The fixing plate assemblies 104 made of metal are located at the top side of the top slots 103. A limiting plate assembly 105 with a V-shaped structure is fixed at the front end of the fixing plate assemblies 104. The outer angle of the limiting plate assembly 105 made of elastic metal is of an arc structure. The bottom of the outer end of the limiting plate assembly 105 is in sliding contact with the included angle position at the rear end of the control member 107, continuously pressing down to fix the moving assembly 106 and the fixing tooth assembly 108, so that the fixing tooth assembly 108 is forced to contact and fix with the circuit.

[0026] In the embodiment of the present disclosure, as Figure 5 shown in Figure 6 the figure, a T-shaped inner slot 201 is penetrated and opened inside the mounting structure 2. After the switch body 1 is fixed, heat dissipation and ventilation can be carried out through the inner slot 201. A limiting hole 202 is opened on the side of the mounting structure 2. A fixing bolt is inserted into the limiting hole 202 to firmly fix the mounting structure 2. Two guiding guiding structures 205 are fixed on the outside of the mounting structure 2 to control the guiding movement of the sliding plate structure 206. A sliding plate structure 206 is slidably installed inside the two guiding structures 205 and can freely slide up and down inside the guiding structures 205. A push rod 207 is respectively fixed at both ends of the sliding plate structure 206 to drive the two push rods 207 to move up and down together. The bottom end of the push rod 207 is of a wedge-shaped structure. The push rod 207 is attached to the side of the switch body 1. The inclined surface of the push rod 207 is in sliding contact with the force-receiving block structure 204, which facilitates pushing the force-receiving block structure 204 and the limiting rod structure 203 to incline. A pressing structure 208 is fixed on the outside of the sliding plate structure 206 and the push rod 207. By conveniently pressing down the pressing structure 208, the sliding plate structure 206 and the push rod 207 are driven to move downward together.

[0027] Working principle of this embodiment: When it is necessary to fix the switch body 1, the fixing bolt can be controlled to fix the installation structure 2 at an appropriate position first, and then the switch body 1 is controlled to be connected to the installation structure 2, so that the limiting rod structure 203 and the force-bearing block structure 204 are guided and inserted into the inside of the card slot 101, so that the switch body 1 and the installation structure 2 are firmly clamped together. Then, the circuit to be connected is controlled to be inserted into the inside of the wire slot 102, and then the control member 107 is pressed. The control member 107 drives the moving assembly 106 and the fixed tooth assembly 108 to move together, so that the fixed tooth assembly 108 is in anti-slip contact and fixation with the circuit. At the same time, the limiting plate assembly 105 continuously presses the moving assembly 106 downward by means of elasticity, so that the fixed tooth assembly 108 is in reverse contact with the circuit, so that after the circuit is pulled, it will not easily come off, and the switch body 1 is firmly installed and used. During the use of the switch body 1, when it is necessary to disassemble and repair the switch body 1, the pressing structure 208 can be directly pressed down to displace, so that the push rod 207 is in sliding contact with the force-bearing block structure 204, and the limiting rod structure 203 is inclined to release the fixation of the switch body 1, and the switch body 1 can be directly pulled up and moved for disassembly, improving the disassembly and maintenance efficiency.
