Description

Technical Field

[0001] The invention relates to a circuit breaker detection technology, and in particular to a new complete set of test equipment for a trolley type circuit breaker. Background Art

[0002] Trolley circuit breakers are generally used in center-mounted high-voltage switchgear. Due to the presence of trolley circuit breakers, center-mounted switchgear is also called trolley high-voltage switchgear. Circuit breakers can not only break and close normal load working currents, but also break and close rated short-circuit currents. Therefore, circuit breakers are often used in conjunction with relays and other components to automatically cut off overload or short-circuit currents in fault circuits.

[0003] A Chinese invention patent with publication number CN112485658A discloses a trolley circuit breaker test device. The trolley circuit breaker test device can adjust the vertical distance between the combined static contact assembly on the first insulating plate and the combined static contact assembly on the second insulating plate by adjusting the spacing between the first insulating plate and the second insulating plate. Since the multiple combined static contact assemblies on the first insulating plate and the multiple combined static contact assemblies on the second insulating plate can move along the axis perpendicular to the support assembly, it is convenient to adjust the spacing between the multiple combined static contact assemblies on the first insulating plate and the spacing between the multiple combined static contact assemblies on the second insulating plate, so that the overall device can be applied to trolley circuit breakers with different sizes of phase spacing and pole spacing, effectively improving the versatility.

[0004] When the existing equipment is in use, due to the staff's lack of knowledge of the test methods or improper operation of the test equipment, the test data will be abnormal, inaccurate, and even potential hidden dangers will be buried in the opponent's car circuit breaker, resulting in misjudgment of the opponent's car circuit breaker status. At the same time, when docking with the circuit breaker, it is impossible to accurately dock with the connection end, which makes it easy for poor contact to occur at the connection, resulting in deviations in the overall test results. Therefore, a new set of test equipment for trolley-type circuit breakers has been developed. Summary of the invention

For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0036] Example: See Figure 1-Figure 8 A new type of complete test device for a trolley-type circuit breaker comprises a base 1, a baffle block 11 is arranged at the upper end of the base 1, a slider 12 is slidably mounted at the upper end of the baffle block 11, a first fixed plate 13 is arranged at the upper end of the slider 12, a telescopic member 14 is arranged at the upper end of the first fixed plate 13, a second fixed plate 15 is arranged at the upper end of the telescopic member 14, and guide grooves 16 are provided at the ends of the first fixed plate 13 and the second fixed plate 15.

[0037] In this solution, the telescopic member 14 is composed of a round rod, a cylinder and a spring. The inner wall of the cylinder is provided with a spring. At the same time, the inner wall of the cylinder is slidably connected to the outer surface of the round rod, and the end of the round rod is in contact with the spring, so that when the second fixed plate 15 moves, the position can be adjusted by moving the round rod to make it suitable for the current scene.

[0038] The guide groove 16 is used to adjust the position of the adjustment component 3, so that when facing trolley-type circuit breakers of different specifications, they can be tested, thereby reducing the time for replacing the testing equipment.

[0039] Furthermore, a leveling assembly 2 is assembled on one side of the base 1, and the handcart-type circuit breaker is positioned by the leveling assembly 2; wherein the leveling assembly 2 includes a fixed block 21 connected to the base 1, and positioning plates 22 are symmetrically arranged at the ends of the fixed block 21, and a rotating drum 23 is slidably installed between the positioning plates 22, and a movable groove 231 is opened on the outer surface of the rotating drum 23, and a protrusion 232 is slidably installed on the inner wall of the movable groove 231.

[0040] In this embodiment, elastic components such as springs are provided at both ends of the rotating drum 23, and the other end of the spring is connected to the positioning plate 22, wherein rotating blocks are provided at both ends of the rotating drum 23, and the outer surface of the rotating block is rotatably connected to the inner wall of the positioning plate 22, so that when the rotating drum 23 moves, the rotating drum 23 is supported by the spring.

[0041] At the same time, one end of the rotating drum 23 passes through and extends to the outside of the positioning plate 22. The protrusion 232 can be moved by rotating the rotating drum 23 in coordination with the movable groove 231. A motor or other power output device can also be provided at the end of the rotating drum 23 and connected to an external control device.

[0042] The control device can select a single-chip microcomputer as the control end. In this embodiment, the single-chip microcomputer is a typical embedded microcontroller (Micro controller unit), which is composed of an arithmetic unit, a controller, a memory, an input and output device, etc., which is equivalent to a microcomputer. Compared with the general-purpose microprocessor used in personal computers, it emphasizes self-supply (no external hardware) and cost saving. Its biggest advantage is that it is small in size and can be placed inside the instrument, but it has a small storage capacity, a simple input and output interface, and low functional consumption.

[0043] Furthermore, a rotating shaft 24 is rotatably mounted on the lower end of the fixing block 21 , an adjusting block 25 is disposed at the end of the rotating shaft 24 , and the end of the adjusting block 25 is connected to the outer surface of the protrusion 232 .

[0044] Specifically, since the adjusting block 25 is connected to the protrusion 232 , when the drum 23 rotates or moves, the adjusting block 25 is synchronously driven to swing, wherein the adjusting block 25 is fixedly connected to the rotating shaft 24 , so that the rotating shaft 24 rotates synchronously with the adjusting block 25 .

[0045] Furthermore, a swing plate 26 is provided at one end of the rotating shaft 24 away from the adjusting block 25, and a driving block 27 is rotatably mounted at both ends of the swing plate 26, and a movable block 271 is provided at the upper end of the driving block 27, and a movable member 28 is provided at the upper end of the movable block 271, and a supporting plate 29 is provided at the upper end of the movable member 28. The outer surface of the movable block 271 is slidably connected to the outer surface of the positioning plate 22.

[0046] Specifically, when the rotating shaft 24 rotates, the swing plate 26 is synchronously driven to rotate, thereby driving the driving block 27 installed at the end of the swing plate 26 to move. At the same time, a movable block 271 is provided at the end of the driving block 27, and the outer surface of the movable block 271 is slidably connected with the outer surface of the positioning plate 22, thereby ensuring that the movable block 271 remains stable as a whole during operation.

[0047] The movable part 28 is a device with telescopic function such as a telescopic rod, and the outer surface of the telescopic rod is provided with elastic parts such as springs. The movable part 28 supports the support plate 29 so that the support plate 29 will not slide when it is in contact with the trolley-type circuit breaker, thereby calibrating the trolley-type circuit breaker before docking, thereby facilitating subsequent docking detection.

[0048] Furthermore, an adjusting component 3 is assembled on the inner wall of the guide groove 16, and the connecting end is adjusted by the adjusting component 3; the adjusting component 3 includes a baffle 31, and a guide cylinder 32 is arranged between the baffles 31, and the outer surface of the guide cylinder 32 is slidably connected to the inner wall of the guide groove 16.

[0049] In this embodiment, the guide cylinder 32 is used to dock with the connection of the opponent car type circuit breaker, and is separated by the baffle 31. The outer surface of the baffle 32 is provided with a ring, and the outer surface of the ring is in contact with the outer surface of the first fixing plate 13.

[0050] The guide cylinder 32 is slidably arranged on the inner wall of the guide groove 16 , so that when different types of trolley-type circuit breakers are detected, the position of each guide cylinder 32 can be adjusted in real time according to the actual situation to make it suitable for the current scene.

[0051] Furthermore, a fixing rod 311 is disposed at the end of the baffle 31 , and the end of the fixing rod 311 passes through and extends to the other end of the baffle 31 . Meanwhile, a pulling rod 312 is disposed at the end of the fixing rod 311 .

[0052] Specifically, the fixing rod 311 can be driven to move by the pull rod 312 , so that when movement is required, the limit block 37 is separated from the first fixing plate 13 , thereby facilitating the operator to move the guide cylinder 32 .

[0053] Furthermore, positioning blocks 33 are provided at the lower end of the baffle 31 and on both sides of the guide cylinder 32. The outer surface of the positioning block 33 is provided with multiple groups of through holes 331, and the multiple groups of through holes 331 are evenly distributed on the outer surface of the positioning block 33. The lower end of the positioning block 33 is provided with a slot 34, and a protective block 35 is slidably installed on the inner wall of the slot 34, and the protective block 35 is located in the inner cavity of the positioning block 33.

[0054] Specifically, when the protection block 35 moves, it is limited by the slot 34, so that the protection block 35 can stably move along the inner wall of the slot 34, effectively reducing the possibility of falling off. The inner cavity of the positioning block 33 is connected to the outside through the through hole 331.

[0055] Furthermore, the inner wall of the protection block 35 is connected to the outer surface of the fixing rod 311, and an elastic member 351 is provided at the end of the protection block 35, and the upper end of the elastic member 351 is connected to the inner wall of the baffle 31. The outer surface of the protection block 35 is provided with a connecting block 352 corresponding to the through hole 331, and the end of the connecting block 352 is rotatably mounted with a push rod 36.

[0056] Specifically, the elastic member 351 is an elastic component such as a spring, and is used to support the protection block 35 so that the protection block 35 remains stable as a whole and is tightly pressed against the inner wall of the positioning block 33 .

[0057] At the same time, when the protection block 35 moves, the connection block 352 arranged on its outer surface is synchronously driven to move. Since the push rod 36 is rotatably installed at the end of the connection block 352, when the connection block 352 moves, the push rod 36 is driven to move.

[0058] Furthermore, a limit block 37 is rotatably mounted on one end of the push rod 36 away from the connection block 352, and a limit rod 38 is rotatably mounted on the middle position of the limit block 37, and the end of the limit rod 38 is fixedly connected to the outer surface of the positioning block 33. The end of the limit block 37 is in contact with the outer surface of the first fixing plate 13.

[0059] Specifically, when the push rod 36 moves, it synchronously drives the limit block 37 installed at its end to move, wherein the limit block 37 is supported by the limit rod 38, so that when the limit block 37 is subjected to force, it rotates around the limit rod 38, thereby moving the limit block 37 away from one end of the push rod 36, so that the limit block 37 is in contact with or separated from the first fixed plate 13.

[0060] The end of the limit block 37 is rotatably mounted with a component having an anti-slip function, such as a rubber block, which moves synchronously with the limit block 37 to ensure stability during positioning.

[0061] The above description is only by way of illustration of certain exemplary embodiments of the present invention. It is undoubted that those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
