Description

Technical Field

[0001] The present invention relates to the technical field of circuit breaker testing, and in particular to a performance testing device for circuit breaker production. Background Art

[0002] Transmission and distribution networks are equipped with numerous circuit breakers, fuses, and other switchgear. These devices are designed to promptly disconnect circuits in the event of a fault, short circuit, or overload, protecting the components and equipment within them and the power grid from further escalation. Therefore, offline testing of circuit breakers during production is crucial to ensure personnel safety and reduce the risk of equipment failure. During production, circuit breakers undergo various performance tests, including those for on / off, closing / opening forces, and thermal system performance, to ensure they meet reliability requirements.

[0003] The existing performance test devices for circuit breaker production have relatively simple functions and cannot meet the needs of comprehensive testing of circuit breaker performance. If the circuit breaker performance is to be fully tested, multiple different test devices must be used, which not only increases production costs and equipment footprint, but also frequently replaces test equipment and adjusts the test environment when conducting multiple performance tests, which easily introduces human errors and affects the reliability of the test results. Moreover, the turnover between multiple test devices not only has low detection efficiency, but also the vacuum circuit breaker product is heavy, and frequent turnover poses certain safety hazards, which brings certain adverse effects to people's use process.

At the same time, the fixed motor 211 controls the movable side plate 213 to move toward the side of the placement groove 29, so that the clamping block 2134 squeezes the vacuum circuit breaker 3 inside the placement groove 29, thereby clamping the vacuum circuit breaker 3, positioning the vacuum circuit breaker 3, maintaining the firmness and stability of the vacuum circuit breaker 3, and facilitating the testing of the vacuum circuit breaker 3.

[0043] Example 3, as Figure 1 - Figure 9 As shown, a performance testing device for circuit breaker production is shown, wherein a side frame 210 is fixedly installed on the side of a fixed platform 21, a bottom frame 214 is fixedly installed on one side of the bottom of the side frame 210, a counting button 215 is fixedly installed on the top of the bottom frame 214, a fixed motor 211 is fixedly installed on one side of the side frame 210, a clamping screw 212 is fixedly installed on the output end of the fixed motor 211, and the clamping screw 212 is rotatably installed between the fixed platform 21 and the side frame 210, a counter is fixedly installed on the side of the fixed platform 21, and the counter is electrically connected to the counting button 215, and a movable side plate 213 is slidably installed between the fixed platform 21 and the side frame 210.

[0044] like Figure 7 - Figure 9 As shown, the movable side plate 213 includes a support plate 2131, and positioning rods 2132 are fixedly installed at both ends of the bottom of the support plate 2131. The positioning rods 2132 at both ends are movably sleeved on both sides of one end of the fixed platform 21, and a moving block 2133 is fixedly installed at the bottom of the support plate 2131. The moving block 2133 is threadedly installed on the outer surface of the clamping screw 212, and the moving block 2133 is slidably installed between the fixed platform 21 and the side frame 210.

[0045] Among them, a clamping block 2134 is fixedly installed on the left end of the left side of the support plate 2131, and the clamping block 2134 is located on the side of the placement groove 29. A rotating shaft 2135 is fixedly installed on the right end of the left side of the support plate 2131. A swing rod 2136 is rotatably installed on the outer surface of the rotating shaft 2135. Sliding grooves 2137 are provided at both ends of the swing rod 2136, and sleeve rods 2138 are fixedly installed at both ends of the swing rod 2136. When the support plate 2131 moves to the side of the fixed platform 21, the clamping block 2134 clamps the vacuum circuit breaker 3 inside the placement groove 29. At this time, the sleeve rods 2138 at both ends of the swing rod 2136 are inserted into the sleeve holes at both ends of the isolation handle 36 to realize the operation of the isolation handle 36.

[0046] Among them, two lifting slots 2140 are opened at the right end of the support plate 2131, and a swing motor 2139 is fixedly installed at the bottom of the right end of the support plate 2131. A rotating rod 2142 is fixedly installed at the output end of the swing motor 2139, and a push rod 2143 is rotatably installed at the other end of the rotating rod 2142. Lifting iron blocks 2146 are slidably installed inside the two lifting slots 2140, and limiting columns 2147 are fixedly installed on the sides of the lifting iron blocks 2146.

[0047] Among them, limiting rods 2141 are fixedly installed on both sides of the right end of the support plate 2131, and the outer surfaces of the limiting rods 2141 on both sides are movably sleeved with sliding sleeves 2144, and the interior of the sliding sleeves 2144 is embedded with electromagnets 2145. Controllers 2148 are fixedly installed on both ends of the right side of the support plate 2131, and the controllers 2148 at both ends are electrically connected to the two electromagnets 2145 respectively.

[0048] Two controllers 2148 and electromagnets 2145 are provided. According to the test results of the vacuum circuit breaker 3, the corresponding controller 2148 controls the electromagnet 2145 to generate magnetism, and through the magnetic attraction of the electromagnet 2145 on the lifting iron block 2146, when the electromagnet 2145 moves up and down, the lifting iron block 2146 moves up and down inside the lifting slot 2140, thereby controlling the swing arm 2136 to rotate around the rotating shaft 2135. When the swing arm 2136 rotates, under the action of the sleeve rods 2138 at both ends of the swing arm 2136, the isolation handle 36 rotates to realize the opening and closing of the isolation switch 35.

[0049] Among them, the top of the pushing rod 2143 is rotatably connected to the sliding sleeve 2144 on the left, and a lifting cylinder 2149 is fixedly installed on the top of the right side of the support plate 2131. The output end of the lifting cylinder 2149 is fixedly installed with a fixed sleeve 2150, and the upper end of the interior of the fixed sleeve 2150 is fixedly installed with a second pressure sensor 2152, and the lower end of the interior of the fixed sleeve 2150 is fixedly installed with a first pressure sensor 2151.

The sliding sleeve 2144 is respectively located between the first pressure sensor 2151 and the second pressure sensor 2152, and the rotating rod 2142 is located at the top of the counting button 215.

[0050] Through the second pressure sensor 2152 at the upper end of the fixed sleeve 2150, when the lifting cylinder 2149 is extended, the fixed sleeve 2150 moves downward, causing the second pressure sensor 2152 at the upper end of the fixed sleeve 2150 to press against the top of the sliding sleeve 2144. The second pressure sensor 2152 is used to detect the pressure pressing on the top of the sliding sleeve 2144, and then the opening force of the isolation handle 36 is detected. In addition, when the lifting cylinder 2149 contracts, the fixed sleeve 2150 moves upward, and the first pressure sensor 2151 at the lower end of the fixed sleeve 2150 is pressed against the bottom of the sliding sleeve 2144. The pressure pressing on the bottom of the sliding sleeve 2144 is detected by the first pressure sensor 2151, thereby realizing the detection of the closing force of the isolation handle 36.

[0051] It should be noted that the present invention is a performance testing device for circuit breaker production. When in use, the operating box 31 of the vacuum circuit breaker 3 is placed inside the fixed platform 21. At this time, the clamping motor 25 is activated, causing the bidirectional screw 26 to rotate, and the limit side plates 27 to move toward each other. The limit side plates 27 at both ends position the operating box 31. Subsequently, the fixed motor 211 controls the clamping screw 212 to rotate, and the movable side plate 213 moves toward the vacuum circuit breaker 3 inside the fixed platform 21, so that the clamping block 2134 is pressed against the side of the vacuum circuit breaker 3 to clamp the vacuum circuit breaker 3. At this time, the sleeve rods 2138 at both ends of the swing rod 2136 are inserted into the sleeve holes at both ends of the isolation handle 36.

[0052] The moving motor 14 controls the rotation of the rotating screw 15, causing the fixing fixture 2 to drive the vacuum circuit breaker 3 on the top to move into the protective cover 16. The vacuum circuit breaker 3 moves to the bottom of the connecting assembly 4. Subsequently, the lifting and wiring cylinders 42 at both ends of the fixed frame 41 extend, causing the fixing plates 43 on both sides to descend. The limit frames 44 at both ends are respectively sleeved on the outer surfaces of the upper wiring terminal 33 and the lower wiring terminal 37, so that the power terminals 45 at both ends of the fixed frame 41 are respectively in contact with the upper wiring terminal 33 and the lower wiring terminal 37;

[0053] The workbench 11 controls the vacuum circuit breaker 3 to switch on and off, and detects the insulation condition of the vacuum circuit breaker 3 through the insulation resistance tester 17. When testing the opening and closing force of the vacuum circuit breaker 3, the controller 2148 at the end of the lifting cylinder 2149 controls the electromagnet 2145 to generate magnetism, so that the electromagnet 2145 at the right end of the support plate 2131 is magnetically connected to the lifting iron block 2146 at the right end. At this time, when the lifting cylinder 2149 contracts, the fixed sleeve 2150 moves upward, and the sliding sleeve 2144 at the right end moves upward, so that the electromagnet 2145 drives the lifting iron block 2146 at the right end to move upward, the swing rod 2136 rotates counterclockwise, and the sleeve rod 2138 rotates counterclockwise. , closing the isolation handle 36, the first pressure sensor 2151 at the lower end of the fixed sleeve 2150 presses against the bottom of the sliding sleeve 2144, and the first pressure sensor 2151 detects the pressure pressing against the bottom of the sliding sleeve 2144, thereby detecting the closing force of the isolation handle 36. Similarly, when the lifting cylinder 2149 extends, the fixed sleeve 2150 moves downward, causing the second pressure sensor 2152 at the upper end of the fixed sleeve 2150 to press against the top of the sliding sleeve 2144, and the sleeve rod 2138 rotates clockwise, thereby opening the isolation handle 36, and the second pressure sensor 2152 detects the pressure pressing against the top of the sliding sleeve 2144, thereby detecting the opening force of the isolation handle 36;

[0054] When the life of the vacuum circuit breaker 3 needs to be tested, the controller 2148 at the left end of the support plate 2131 works, and the controller 2148 at the right end of the support plate 2131 stops working. The electromagnet 2145 at the left end of the support plate 2131 generates magnetic attraction for the lifting iron block 2146. At this time, the swing motor 2139 controls the rotating rod 2142 to rotate. The rotating rod 2142 rotates and pushes the sliding sleeve 2144 at the top of the push rod 2143 to move up and down on the outer surface of the limit rod 2141. The movement of the sliding sleeve 2144 causes the left end lifting iron block 2146 to move up and down in the lifting groove 2140. When the rotating rod 2142 rotates one circle, the sliding sleeve 2144 completes one lifting and lowering. At the same time, the vacuum circuit breaker 3 completes one opening and closing. When the rotating rod 2142 rotates, it presses the top of the counting button 215 and is counted by the counter. When the number reaches the required value, it is a qualified product, otherwise it is an unqualified product.
