Description

Technical Field

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

[0002] High-voltage circuit breakers play a controlling role in high-voltage circuits and are one of the important electrical components in high-voltage circuits. Circuit breakers are used to connect or disconnect circuits during normal operation. In the event of a fault, they quickly disconnect the circuit under the action of a relay protection device. In special circumstances (such as when automatically reclosing to a faulty line), they can reliably connect short-circuit currents.

[0003] High-voltage circuit breakers need to be regularly tested for characteristics during use. Characteristics tests are generally performed using characteristic testers, which are mainly used to evaluate the performance of high-voltage circuit breakers and diagnose faults to ensure safe operation.

[0004] High-voltage circuit breakers are usually installed in the air, so they need to be lifted out by electric hoists before testing. At that time, the electric hoists are lifted by ropes. When the electric hoists start and stop, the speed difference will cause the high-voltage circuit breakers and ropes to swing due to inertia. The high-voltage circuit breakers are prone to injuries and damage due to collisions during the swinging process.

[0005] At the same time, during the characteristic test, the detection line of the characteristic tester needs to be connected to the moving / static contacts of the high-voltage circuit breaker. Generally, the characteristic tester and the high-voltage circuit breaker are placed directly on the ground, so the detection line will also be placed on the ground in a messy manner. Hard or heavy objects rolling on the ground may cause mechanical damage to the detection line, affecting the service life and safety performance of the detection line. Therefore, an auxiliary equipment is urgently needed to solve the above problems to improve the detection efficiency. Summary of the invention

[0016] As a preferred solution of the auxiliary equipment for testing the mechanical characteristics of circuit breakers described in the present invention, the support assembly includes a guide groove 1 opened on the upper surface of the base plate and a rotating member fixed on the upper surface of the base plate at one end of the guide groove 1, a diagonal strut 1 is rotatably connected to the inner side of the rotating member, a diagonal strut 2 rotatably connected to the diagonal strut 1 is slidably connected to the inner side of the guide groove 1, a guide groove 2 is opened on the upper surface of the diagonal strut 1, and a diagonal strut 3 rotatably connected to the bottom of the load guide rail is slidably connected in the guide groove 2.

[0017] As a preferred solution of the auxiliary equipment for circuit breaker mechanical characteristic test described in the present invention, the detection part includes a detector installed on one side of the platform and a bracket fixed on the upper surface of the platform, a wiring tube is embedded in the interior of the detector, two rows of wiring tubes are installed on the bracket, an electrode head is installed at one end of the wiring tube, and a detection line electrically connected to the electrode head is plugged into the wiring tube, and the other end of the detection line is connected to the detection port of the wiring tube.

[0032] In the following description, many specific details are set forth to facilitate a full understanding of the present invention, but the present invention may also be implemented in other ways different from those described herein, and those skilled in the art may make similar generalizations without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

The term "in one embodiment" that appears in different places in this specification does not necessarily refer to the same embodiment, nor does it refer to a separate or selective embodiment that is mutually exclusive with other embodiments.

[0034] Secondly, the present invention is described in detail with reference to the schematic diagram. When describing the embodiments of the present invention in detail, for the sake of convenience, the cross-sectional diagrams showing the device structure will not be partially enlarged according to the general scale, and the schematic diagrams are only examples, which should not limit the scope of protection of the present invention. In addition, in actual production, the three-dimensional dimensions of length, width and depth should be included.

[0035] Example 1

[0036] Reference Figure 1-2 , 4-6, an auxiliary device for testing mechanical characteristics of a circuit breaker, comprising:

[0037] High voltage circuit breaker 100;

[0038] The test bench portion 200 is used to carry the high voltage circuit breaker 100 when performing a mechanical property test;

[0039] The detection part 300 is installed on the detection platform part 200 and is used for testing the mechanical characteristics of the high voltage circuit breaker 100 .

[0040] Furthermore, the detection platform part 200 includes a base plate 201 and a platform 202 arranged above the base plate 201. A lifting component 203 for driving the platform 202 to move up and down is installed above the base plate 201, and lifting guide rods 204 are vertically fixed at both ends above the base plate 201. The lifting guide rods 204 pass through the platform 202 and are used to play a guiding role during displacement.

[0041] Furthermore, a load rail 205 is symmetrically fixed to the front side of the platform 202 , and the load rail 205 is used to carry the high-voltage circuit breaker 100 .

[0042] Specifically, a storage plate is slidably installed in the load guide rail 205, and a rotating disk is embedded in the surface of the storage plate. When the high-voltage circuit breaker 100 needs to be tested, the test platform 200 is partially pushed to the installation site of the high-voltage circuit breaker 100 to be tested. Two moving wheels and two universal locking moving wheels are installed at the bottom of the bottom plate 201, so it has the functions of moving and locking;

[0043] After moving to the destination, the lifting assembly 203 controls the platform 202 to rise to the installation height of the high-voltage circuit breaker 100. Two load guide rails 205 are respectively placed on both sides of the bottom of the high-voltage circuit breaker 100. The high-voltage circuit breaker 100 is dragged to slide backward until it is completely moved to the turntable on the storage plate. The high-voltage circuit breaker 100 is rotated 180° by using the rotation ability of the turntable, so that the moving / static contact side of the high-voltage circuit breaker 100 faces the platform 200. This structure can play an auxiliary disassembly and assembly function when detecting the high-voltage circuit breaker 100, solves the disadvantages of traditional lifting and disassembly, and effectively ensures the safety of the operator and the equipment itself.

[0044] Furthermore, the lifting assembly 203 includes a rod body 203a fixed to the bottom of the platform 202 and a side plate 203b installed on the upper surface of the base plate 201, and a finger lifting member 203c for lifting the platform 202 is installed on the side plate 203b, and a descending member 203d for controlling the descent of the platform 202 is installed on the side plate 203b.

[0045] Specifically, the finger lifting member 203c includes a rack groove 203c-1 opened on one side of the rod body 203a and a rotating block 203c-2 rotatably connected to the inner side of the side plate 203b, one end of the rotating block 203c-2 is movably connected to the finger 203c-3, and the other end of the rotating block 203c-2 is rotatably connected to the connecting rod 203c-4, the bottom end of the connecting rod 203c-4 is movably connected to the linkage rod 203c-5, the bottom of the linkage rod 203c-5 is provided with a hydraulic rod 203c-6, the other end of the linkage rod 203c-5 is rotatably connected to the platform 202, and the linkage rod 203c-5 is rotatably connected to the platform 202. The rod 203c-5 is arranged at an inclination, and a strip-shaped through groove is provided on one side of the bottom of the linkage rod 203c-5 connected to the linkage rod 203c-4. Both sides of the bottom of the linkage rod 203c-4 are fixed with protrusions that slide in the strip-shaped through groove. When the platform needs to rise, the linkage rod 203c-5 is stepped on to make it move in a circle along the connection with the platform 202 as a fulcrum, so that the other end of the linkage rod 203c-5 pulls the linkage rod 203c-4 downward to move downward. When the linkage rod 203c-4 moves downward, it will pull the rotating block 203c-2 to rotate. The middle section of the rotating block 203c-2 is rotatably connected to the side plate 203b, so when the platform is raised, the linkage rod 203c-5 is stepped on to make it move in a circle along the connection with the platform 202 as a fulcrum, so that the other end of the linkage rod 203c-5 pulls the linkage rod 203c-4 downward to move downward. When the linkage rod 203c-4 moves downward, it will pull the rotating block 203c-2 to rotate. The middle section of the rotating block 203c-2 is rotatably connected to the side plate 203b. The connecting rod 203c-4 pulls the lower rotating block 203c-2 to rotate with the middle section as the fulcrum, so one end of it moves downward and the other end moves upward. During the upward movement, the finger 203c-3 pushes the rack groove 203c-1 upward, thereby realizing the rise of the platform 202. When the foot stops applying pressure to the linkage rod 203c-5, the reaction force of the hydraulic rod 203c-6 will drive the linkage rod 203c-5 to reset, so that the finger 203c-3 is re-stuck in the rack groove 203c-1 downward, and the finger 203c-3 can slide elastically horizontally in the rotating block 203c-2. Therefore, when the finger 203c-3 moves downward, it touches the outer side of the rack groove 203c-1 and slides inward along the inner side of the rotating block 203c-2. When it is not restricted, it is reset and re-engaged in the rack groove 203c-1 under the action of the elastic member. Therefore, the continuous rising action is achieved by repeatedly stepping on the linkage rod 203c-5. This structure does not require electricity, has the advantages of simple operation and reliable transmission, and reduces energy consumption compared to electric drive. At the same time, compared with the hydraulic rising structure, it has the advantage of simple maintenance, which solves the complexity and difficulty of checking the cleanliness of the hydraulic oil and the sealing of the hydraulic cylinder during the maintenance of the hydraulic rising structure.

[0046] The descending member 203d includes a guide ring 1 203d-1 and a guide ring 203d-2 fixed to the inner side of the side plate 203b, a movable rod 1 203d-3 is movably connected in the guide ring 1 203d-1, and a movable rod 203d-4 is movably connected in the guide ring 203d-2. One end of the movable rod 1 203d-3 is rotatably connected to a connecting piece 1 203d-5, and one end of the movable rod 203d-4 is rotatably connected to a connecting piece 203d-6. The other ends of the connecting piece 1 203d-5 and the connecting piece 2 203d-6 are both rotatably connected to the main rod 203d-7. The bottom of the main rod 203d-7 is fixed with an intermediate rod 203d-8, and the outer portion of the intermediate rod 203d-8 is sleeved with a guide rod fixed to the inner side of the side plate 203b. Ring three 203d-9, and the outer part of the middle rod 203d-8 is sleeved with a spring 203d-10, the bottom of the middle rod 203d-8 is connected with a linkage rod 203d-11, the other end of the linkage rod 203d-11 is rotatably connected to the platform 202, and the linkage rod 203d-11 is inclined, and the side of the linkage rod 203d-11 connected to the bottom of the middle rod 203d-8 is provided with a strip through groove 2, and both sides of the bottom of the middle rod 203d-8 are fixed with protrusions 2 that slide in the strip through groove 2. When descending, first slide the finger 203c-3 to release it from the rack groove 203c-1, step on the linkage rod 203d-11, and the other end of the linkage rod 203d-11 pulls the middle rod 203d- 8 moves downward, a pressure sheet is installed on the middle rod 203d-8, and as the middle rod 203d-8 moves downward, the pressure sheet will compress the spring 203d-10, and at the same time drive the main rod 203d-7 to move downward, and the downward movement of the main rod 203d-7 will drive the connecting piece 1 203d-5 and the connecting piece 2 203d-6 to move, and the connecting piece 1 203d-5 changes from a slight inclination to vertical, and the connecting piece 203d-6 changes from vertical to slightly inclined, so the connecting piece 1 203d-5 will drive the movable rod 1 203d-3 and the connecting piece 2 203d-6 to move in the opposite direction of the guide ring 1 203d-1 and the guide ring 2 203d-2 respectively, and a triangular head is arranged at one end of the movable rod 1 203d-3, and three equidistantly arranged at the outer side of the rod body 203a corresponding to the position of the triangular head The inclined surfaces of the angle teeth, triangular teeth and triangular heads face downward and fit each other. After the movable rod 203d-3 moves, the triangular teeth and the triangular head are separated, so the rod body 203a is not restricted and will slide downward. After sliding to the appropriate position, the linkage rod 203d-11 is released, and the movable rod 203d-3 is reset under the reaction force of the spring 203d-10, so that the triangular head is stuck in the triangular teeth, forming a restriction on the rod body 203a, so that the platform 202 stops at the required height, and has a simple adjustment function. At the same time, when rising, the triangular head will retreat as the inclined surface of the triangular teeth of the rod body 203a rises. At the same time, when the triangular head is not compressed, it will be stuck in the triangular teeth under the action of the spring 203d-10 to prevent sliding downward, thereby improving the reliability of operation.

[0047] Furthermore, the detection part 300 includes a detector 301 installed on one side of the platform 202 and a bracket 302 fixed on the upper surface of the platform 202. A wiring tube 303 is embedded in the interior of the detector 301, and two rows of wiring tubes 303 are installed on the bracket 302. An electrode head 304 is installed at one end of the wiring tube 303, and the wiring tube 303 is plugged with a detection line 305 electrically connected to the electrode head 304, and the other end of the detection line 305 is connected to the detection port of the wiring tube 303.

[0048] Specifically, during detection, the storage plate in the load guide rail 205 is pushed to displace the high-voltage circuit breaker 100 until the moving / static contacts on the high-voltage circuit breaker 100 are sleeved on the electrode head 304. The electrode head 304 is a conical structure, so it can better fit the moving / static contacts to ensure the accuracy of detection. At the same time, the length of the detection line 305 of this structure is fixed, and there will be no problems of being too long or dragging on the ground. This solves the problem that the traditional detection harness dragging on the ground does not meet the construction requirements, reduces the difficulty of detection, and improves the overall detection efficiency and accuracy.

[0051] Specifically, the support assembly 206 includes a guide groove 1 206a provided on the upper surface of the bottom plate 201 and a rotating member 206b fixed on the upper surface of the bottom plate 201 at one end of the guide groove 1 206a, the rotating member 206b is rotatably connected to a diagonal support 1 206c on the inner side, a diagonal support 206d rotatably connected to the diagonal support 1 206c is slidably connected to the inner side of the guide groove 1 206a, a guide groove 206e is provided on the upper surface of the diagonal support 1 206c, and a diagonal support 3 206f rotatably connected to the bottom of the load guide rail 205 is slidably connected in the guide groove 206e;

[0052] When the load guide rail 205 rises with the platform 202, the diagonal support three 206f drives one end of the diagonal support one 206c to move upward, and the rise of the diagonal support one 206c drives the diagonal support two 206d upward, forming two right-angled triangles between the diagonal support three 206f, the diagonal support one 206c and the diagonal support two 206d, which can provide stable support.

[0053] The rest of the structure is the same as that of Example 1.

[0054] Example 3

[0055] Reference Figure 7 This embodiment is different from the above embodiments in that: in the auxiliary equipment for testing the mechanical characteristics of a circuit breaker in this embodiment, the detection part 300 also includes an adjustment component 306 installed on the bracket 302, and the adjustment component 306 is used to drive the two rows of wiring tubes 303 to adjust the equal spacing so as to adapt to the spacing of different moving / static contacts on the high-voltage circuit breaker 100.

[0056] Furthermore, the adjustment component 306 includes two movable plates 306a, which are respectively located on the upper and lower sides of the bracket 302, and a horizontal groove 306b is provided on the surface of the movable plate 306a at the middle position, and oblique grooves 306c are symmetrically provided on the surface of the movable plate 306a on both sides of the horizontal groove 306b, and guide columns 306d are penetrated in the horizontal groove 306b and the oblique groove 306c, and the other end of the guide column 306d is fixed on the wiring tube 303.

[0057] Furthermore, the two movable plates 306a achieve relative displacement of the wiring tube 303 through displacement of the driving member;

[0058] Specifically, the driving member includes a through slot 1 306e and a through slot 2 306f provided on the upper surface of the bracket 302, a connecting strip 306g is fixed between the two corresponding brackets 302, the connecting strip 306g slides in the through slot 2 306f, a fixing column 306h runs through the through slot 1 306e, both ends of the fixing column 306h are respectively fixed to the two movable plates 306a, the fixing column 306h is driven by the electric telescopic rod 306i, and the telescopic end of the electric telescopic rod 306i is connected to the fixed plate 306a. The column 306h is fixed, so the electric telescopic rod 306i drives the fixed column 306h to slide in the through slot 1 306e when it is in operation. Since the two movable plates 306a are fixed to the fixed column 306h, the electric telescopic rod 306i drives the two movable plates 306a to move when it is extended or retracted. During the displacement process, the inclined groove 306c drives the wiring tube 303 to move horizontally at equal intervals through the guide column 306d, so as to adapt to the spacing of different moving / static contacts on the high-voltage circuit breaker 100, and has high adaptability.
