[0035] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0036] Please see Figure 1-4In this embodiment of the invention, a high-voltage switch dynamic characteristic tester includes a tester body 100. A main control area 110 is installed on one side of the top of the tester body 100. The main control area 110 includes a slot for power cord insertion and a control switch for controlling the opening and closing of the tester body 100. By connecting both ends of the power cord to the slot and an external power source respectively, the tester body 100 can be powered, and the start and stop of the tester body 100 can be controlled by the control switch. A terminal block 120 is installed on one side of the top of the tester body 100. By connecting the terminal block 120 to the high-voltage switch with a wire, the circuit of the high-voltage switch can be connected to the test. Inside the instrument body 100, a detection module for data collection and processing is installed. The terminal block 120 is electrically connected to the detection module. A display screen 130 for displaying data is installed on the other side of the top of the instrument body 100. A button 131 for controlling the display screen 130 is installed on the top of the instrument body 100, located on one side of the display screen 130. Both the button 131 and the display screen 130 are electrically connected to the detection module. The detection module collects and processes the high-voltage switch data connected to the terminal block 120. The processing results are displayed on the display screen 130, and the detection function can be adjusted by the button 131.

[0037] The testing instrument body 100 has slots on both sides that communicate with its interior. A heat sink 200 is installed inside each slot, and a cooling fan is installed inside to assist airflow exchange. A docking plate 210 is installed at both ends of the heat sink 200, and the docking plate 210 is bolted to the side wall of the testing instrument body 100. A heat dissipation slot 220 for gas entry and exit is opened at the end of the heat sink 200 away from the testing instrument body 100. A first partition 230 and a second partition 231 are installed on the inner wall of the heat sink 200 to divide the internal space. Air vents are opened at both ends of the first partition 230 and the second partition 231 for gas passage, and a heat sink is installed inside each vent. A one-way valve is provided to control the gas flow direction. A cooling box 300 is installed between the first partition 230 and the second partition 231. Both the first partition 230 and the second partition 231 are T-shaped. The first partition 230, the second partition 231 and the cooling box 300 together divide the interior of the heat dissipation box 200 into three independent chambers at the top and bottom. External gas enters the tester body 100 through the three chambers at the top in sequence. The gas inside the tester body 100 is discharged from the heat dissipation slot 220 through the three chambers at the bottom in sequence. This can separate the incoming and outgoing gas and avoid heat exchange between the incoming and outgoing gas, which would affect the heat dissipation effect inside the tester body 100.

[0038] The cooling chamber 300 is equipped with a compression component for compressing gas and a cooling component for assisting heat dissipation by compressing gas. The compression component and the cooling component are connected by a pipe. The compression component compresses the gas entering and leaving the cooling chamber 200 and delivers it to the cooling component. The cooling component cools the gas entering the cooling chamber 200 by compressing the gas, thus assisting the heat dissipation of the test instrument body 100.

[0039] A purification box 400 is installed on the top of the first partition 230. The purification box 400 contains a purification component for removing impurities and drying the gas. The cooling component is connected to the purification component through a pipe. The purification component removes impurities and dries the gas entering the tester body 100, keeping the inside of the tester body 100 clean while preventing excessive humidity inside the tester body 100 from causing a short circuit and affecting the normal use of the tester body 100. In addition, the cooling component cools the gas entering the tester body 100, improving the heat dissipation effect inside the tester body 100.

[0040] See Figure 4 - Figure 7 The cooling component includes a vortex tube 310, which is installed in the middle of the inner wall of the refrigeration box 300. Mounting brackets 311 are installed at both ends of the vortex tube 310, and the mounting brackets 311 are installed on the inner walls of both sides of the refrigeration box 300. The vortex tube 310 has three interfaces: a nozzle in the middle for gas entry, a cold end interface at one end for cold air, and a hot end interface at the other. A cold air pipe 312 connects to the cold end interface of the vortex tube 310. The tail end of the cold air pipe 312 extends through the refrigeration box 300 to the top between the first partition 230 and the second partition 231. The hot end interface of the flow pipe 310 is connected to a hot gas pipe 313. The tail end of the hot gas pipe 313 passes through the refrigeration box 300 and extends to the bottom between the first partition 230 and the second partition 231. The cold gas is discharged to the top between the first partition 230 and the second partition 231 through the cold gas pipe 312 to cool the gas entering the tester body 100. The hot gas is discharged into the bottom of the first partition 230 and the second partition 231 through the cold gas pipe 312. The gas discharged from the tester body 100 can carry the hot gas and discharge it to the outside through the heat dissipation slot 220 to dissipate heat inside the tester body 100.

[0041] The extrusion assembly includes a fixed sleeve 320. The refrigeration box 300 has through holes at both ends. The fixed sleeve 320 is installed on the inner wall of the refrigeration box 300 at the axis of the through holes. The refrigeration box 300 is connected to the first partition 230 and the chamber between the first partition 230. Compression boxes 340 are installed at both ends of the inner wall of the fixed sleeve 320. An exhaust pipe 342 for exhaust is installed on one side of the two compression boxes 340 at an axial position. An intake pipe 341 for intake is installed on the opposite side of the two compression boxes 340. A gas delivery pipe 321 is connected to the nozzle of the vortex pipe 310. Two branch pipes are installed at the gas delivery pipe 321. The tail ends of the two branch pipes are connected to the middle of the inner wall of the fixed sleeve 320.

[0042] The extrusion assembly also includes a fixed turbine 343 and a movable turbine 344. Both the fixed turbine 343 and the movable turbine 344 are spiral in the same direction. A gas channel is provided between the movable turbine 344 and the fixed turbine 343. Gas enters the gas channel at the outer ring of the fixed turbine 343 and the movable turbine 344 through the inlet pipe 341 and moves along the gas channel to the inner ring. Then, it is discharged into the middle of the inner wall of the fixed sleeve 320 through the outlet pipe 342. The fixed turbine 343 is fixedly connected to the inner wall of the compression box 340, and the movable turbine 344 is movably connected to the inner wall of the compression box 340. By moving the movable turbine 344, the size of the gas channel is gradually reduced, and the gas is gradually squeezed and compressed in the gas channel to increase the gas pressure.

[0043] A motor housing 330 is installed in the middle of the inner wall of the fixed sleeve 320. Both ends of the motor housing 330 have built-in drive motors. The output end of the drive motor is equipped with a rotating shaft 331. A connecting plate 345 is installed on the inner ring of the movable turbine 344. The connecting plate 345 is eccentrically fixed to the end of the rotating shaft 331. When the drive motor drives the rotating shaft 331 to rotate, the rotating shaft 331 drives the movable turbine 344 to move through the connecting plate 345. The connecting plate 345 is eccentrically installed at the rotating shaft 331. When the rotating shaft 331 rotates, the connecting plate 345 drives the movable turbine 344 to move, thereby adjusting the gas passage between the movable turbine 344 and the fixed turbine 343.

[0044] Two compression boxes 340 are each equipped with a semiconductor chip 332 at opposite ends. The two semiconductor chips 332 are N-type and P-type, respectively. The semiconductor chips 332 at both ends are connected in the same circuit, and the semiconductor chips 332 are connected to the drive motor in the same path. The top semiconductor chip 332 and the bottom semiconductor chip 332 are affected by the temperature difference between the gas, and a current is generated in the circuit formed by the two semiconductor chips 332 to power the drive motor.

[0045] See Figure 8 - Figure 11The purification component includes a purification block 420, which is installed on the inner wall of the bottom of the purification box 400. Both ends of the purification block 420 are provided with multiple linearly arranged capillary holes 422. The middle of the purification block 420 is provided with an installation groove 421. The capillary holes 422 are inclined, with one end extending into the installation groove 421 and the other end passing through the outer wall of the purification box 400. When external gas enters the heat dissipation box 200 through the heat dissipation groove 220, it passes through the capillary holes 422 on the purification box 400 and through the installation groove 421 and the capillary holes 422 at the other end. When the gas passes through the capillary holes 422, the small pore size can filter impurities, and the small pore size can capture water molecules through van der Waals forces, adsorbing water molecules.

[0046] An outer shell 430 is installed on the inner wall of the mounting slot 421. An inner rod 431 is installed on the inner wall of the outer shell 430. The inner rod 431 is made of elastic material. Multiple first connecting holes 432 arranged linearly are opened in the inner rod 431. Multiple second connecting holes 433 arranged linearly are opened on the outer wall of the outer shell 430. The second connecting holes 433 are connected to the first connecting holes 432 and are connected to the capillary pores 422 at both ends.

[0047] An electric push rod 410 is installed on the top inner wall of the purification box 400. A transmission plate 411 is installed at the bottom of the electric push rod 410. The transmission plate 411 is slidably connected to the inner wall of the purification box 400. Multiple linearly arranged extrusion blocks 412 are fixedly connected to the bottom end of the transmission plate 411. The extrusion blocks 412 and the inner rod 431 are located in the same axial direction and have the same diameter. Both ends of the purification block 420 are provided with drainage channels 423. The drainage channels 423 pass through the capillary holes 422 and pass through the bottom of the purification box 400 and the first partition 230. When drainage is required, the electric push rod 410 extends to drive the transmission plate 411 and the extrusion blocks 412 to extrude the inner rod 431. The inner rod 431 is deformed by the extrusion and passes through the second connecting hole 433 into the capillary holes 422. This can extrude the water that is retained in the capillary holes 422 to the drainage channels 423 and then drain it into the bottom chamber of the first partition 230.

[0048] More specifically, the inner rod 431 is made of rubber, and the inner wall of the outer shell 430 is provided with a fur coating. Specifically, when the inner rod 431 is compressed and deformed, friction is generated between the inner rod 431 and the inner wall of the outer shell 430, and static electricity is generated on the inner rod 431. The static electricity on it can improve the ability to capture water molecules and improve the water absorption effect.

[0049] A heat exchange tube 434 is installed on the inner wall of the outer shell 430. The heat exchange tube 434 is spiral in shape. The second connecting hole 433 is connected to the cold air pipe 312. The cold air pipe 312 sends the cold end gas into the heat exchange tube 434. The heat exchange tube 434 surrounds the inner wall of the outer shell 430. The gas can be cooled down by the cold end gas when it passes through the outer shell 430, which dissipates heat into the test instrument body 100.

[0050] The working principle of this invention is as follows: when heat dissipation is required, external airflow enters the heat dissipation box 200 through the heat dissipation groove 220, and enters the test instrument body 100 through the three chambers at the top of the heat dissipation box 200 in sequence. The gas in the test instrument body 100 is discharged through the heat dissipation groove 220 through the three chambers at the bottom of the heat dissipation box 200 in sequence.

[0051] The semiconductor chips 332 at both ends receive the temperature difference between the two ends and generate current under the Peltier effect to power the drive motor in the motor housing 330. The drive motor drives the connecting plate 345 to rotate eccentrically through the rotating shaft 331, thereby driving the movable turbine 344 to move back and forth. The gas between the first partition 230 and the second partition 231 is drawn into the compression box 340 through the air inlet pipe 341. The gas enters the gas channel between the fixed turbine 343 and the movable turbine 344. The gas flows into the middle along the spiral of the gas channel. At the same time, the movable turbine 344 moves back and forth to gradually reduce the inner diameter of the gas channel and gradually pressurize the gas. The pressurized gas is discharged into the middle of the inner wall of the fixed sleeve 320 through the air outlet pipe 342 and is transported to the vortex tube 310 through the air delivery pipe 321. The vortex tube 310 discharges the compressed gas from the cold air pipe 312 and the hot air pipe 313 respectively. The cold air in the cold air pipe 312 enters the heat exchange tube 434.

[0052] When the external gas passes through the purification box 400, it passes through the capillary pores 422 and the outer shell 430, filtering out impurities in the gas and capturing water molecules in the gas. The heat exchange tube 434 can exchange heat with the gas to cool it down. The cooled gas enters the tester body 100 to assist in heat dissipation.

[0053] When drainage is needed, the electric actuator 410 is activated. The electric actuator 410 drives the extrusion block 412 to extrude the inner rod 431 through the transmission plate 411. The inner rod 431 deforms and passes through the second connecting hole 433 into the capillary hole 422, squeezing the water in the capillary hole 422 into the drainage channel 423 for discharge.

[0054] The hot air from the hot air pipe 313 can be discharged along with the gas exchanged in the tester body 100, and the water discharged from the drainage channel 423 can be carried out to the outside of the tester body 100.

[0055] When in use, the present invention, through the compression component, cooling component, and purification component, can improve the heat dissipation effect inside the tester body 100 by cooling the gas entering the tester body 100, without the need for external power supply, thus avoiding the generation of additional heat sources that would affect the heat dissipation effect. Furthermore, it can remove impurities and dry the gas entering the tester body 100, preventing impurities from entering the tester body 100 and affecting the electronic equipment of the tester body 100, and also preventing excessive humidity inside the tester body 100 from causing short circuits and affecting the normal use of the tester body 100.

[0056] The semiconductor chip 332, through the temperature difference between its two ends, can generate current to power the drive motor under the Peltier effect. Furthermore, the temperature difference between the upper and lower ends of the semiconductor chip 332 can be gradually increased by the hot and cold gas ejected from the cold gas pipe 312 and the hot gas pipe 313, thereby improving the gas compression efficiency of the drive motor, and thus improving the efficiency of cold gas generation and the heat dissipation effect on the test instrument body 100.

[0057] The electric push rod 410, outer shell 430 and inner rod 431 can discharge the water adsorbed by the capillary pores 422, preventing water from remaining in the capillary pores 422. When air passes through, it carries water molecules, which can cause excessive humidity inside the tester body 100 and affect the normal use of the tester body 100.

[0058] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
