[0001] This invention relates to the field of testing technology for deeply fused solid-sealed terminals for pole-mounted switches, and particularly to a tooling for comprehensive testing of deeply fused solid-sealed terminals for pole-mounted switches. Background Technology

[0002] The demand for deeply integrated solid-sealed poles for pole-mounted switches is gradually expanding. Their structure is a combination of solid-sealed poles, current transformers, and sensors. The test items include the circuit resistance, power frequency withstand voltage, and partial discharge required for solid-sealed poles, the secondary withstand voltage and accuracy error of current transformers, and the accuracy error and electromagnetic interference of sensors. The tests are numerous and complex, requiring frequent changes of different test fixtures and equipment, which is inconvenient and inefficient.

[0003] Therefore, how to promote the rapid transfer of deeply integrated solid-sealed electrodes in various test stages to save switching time and manpower and improve test efficiency is a technical problem that needs to be solved by those skilled in the art. Summary of the Invention

[0004] The purpose of this invention is to provide a tooling for comprehensive testing of deeply integrated solid-sealed terminals of pole-mounted switches, which can facilitate the rapid transfer of deeply integrated solid-sealed terminals in various test stages, thereby saving switching time and manpower and improving test efficiency.

[0005] To achieve the above objectives, the present invention provides a fixture for comprehensive testing of deeply integrated solid-sealed pole posts of pole-mounted switches, comprising an insulating platform, a positioning support block, an inlet end limiting block, a bottom limiting block, and a power source. The positioning support block, the inlet end limiting block, the bottom limiting block, and the power source are all disposed on the top of the insulating platform. The positioning support block is used to support the deeply integrated solid-sealed pole post. The inlet end limiting block and the bottom limiting block are disposed opposite to each other in a first direction and are respectively located on different sides of the positioning support block in the first direction, thereby restricting the movement of the deeply integrated solid-sealed pole post in the first direction. The output end of the power source is used to connect to the insulating pull rod of the deeply integrated solid-sealed pole post and to drive the insulating pull rod to move in the first direction.

[0006] In one possible implementation, the positioning support block includes an upper positioning support block and a lower positioning support block spaced apart in a first direction. The upper positioning support block is used to support the upper outer shell of the deep fusion solid-sealed pole, and the lower positioning support block is used to support the lower outer shell of the deep fusion solid-sealed pole.

[0009] In one possible implementation, the inner wall of the first limiting groove is provided with a first buffer pad, and the inner wall of the second limiting groove is provided with a second buffer pad.

[0010] In one possible implementation, there are multiple first limiting grooves and multiple second limiting grooves. The multiple first limiting grooves are evenly arranged on the upper positioning support block along the second direction, and the multiple second limiting grooves are evenly arranged on the lower positioning support block along the second direction.

[0011] In one possible implementation, the inlet end limiting block, the bottom limiting block, the first limiting groove, and the second limiting groove correspond one-to-one, and the corresponding inlet end limiting block, bottom limiting block, first limiting groove, and second limiting groove are linearly distributed in the first direction.

[0012] In one possible implementation, a bracket is provided between the power source and the insulating platform. The bracket is located on the side of the bottom limiting block away from the inlet limiting block. The bracket corresponds to the power source and the bottom limiting block.

[0013] In one possible implementation, the insulating platform is further provided with a quick-connect clamp for connecting to the secondary lead of the deeply fused solid-sealed pole.

[0014] In one possible implementation, a movable frame is connected to the bottom of the insulated platform, and the bottom of the movable frame is equipped with casters.

[0015] Compared with the prior art, the technical solution provided by the present invention has at least the following beneficial effects: the positioning support block is used to support the deep fusion solid-seal pole; the inlet end limiting block and the bottom limiting block are arranged opposite to each other in the first direction and are respectively located on different sides of the positioning support block in the first direction, which is used to limit the movement of the deep fusion solid-seal pole toward the inlet end limiting block and toward the bottom limiting block in the first direction, so that the position of the deep fusion solid-seal pole is fixed; the output end of the power source is connected to the insulating pull rod of the deep fusion solid-seal pole; the output end of the power source drives the insulating pull rod to move closer to the inlet end limiting block in the first direction and applies a certain pressure to the insulating pull rod, providing rated contact pressure for loop resistance testing and pressure and simulating the use state for accuracy testing; the output end of the power source drives the insulating pull rod to move away from the inlet end limiting block in the first direction, so that the inlet and outlet circuits of the deep fusion solid-seal pole are disconnected by a certain distance, providing an opening distance for power frequency withstand voltage and partial discharge testing; in this way, the deep fusion solid-seal pole can be quickly transferred in each test stage, saving switching time and manpower, and improving test efficiency.

Detailed Implementation

[0019] 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.

[0020] To enable those skilled in the art to better understand the present invention, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0021] In the description of this invention, it should be understood that the terms "top," "bottom," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the position or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations of this invention.

[0022] The purpose of this invention is to provide a tooling for comprehensive testing of deeply integrated solid-sealed terminals of pole-mounted switches, which can facilitate the rapid transfer of deeply integrated solid-sealed terminals in various test stages, thereby saving switching time and manpower and improving test efficiency.

[0023] It should be noted that in this embodiment, the X direction in the attached figure is defined as the first direction, and the Y direction is defined as the second direction. The first direction and the second direction are perpendicular to each other.

[0024] Please see Figures 1 to 15To achieve the above objectives, the present invention provides a fixture for comprehensive testing of deeply integrated solid-sealed pole posts of pole-mounted switches, comprising an insulating platform 11, a positioning support block, an inlet end limiting block 14, a bottom limiting block 15, and a power source 16. The positioning support block, the inlet end limiting block 14, the bottom limiting block 15, and the power source 16 are all disposed on the top of the insulating platform 11. The positioning support block is used to support the deeply integrated solid-sealed pole post 31. The inlet end limiting block 14 and the bottom limiting block 15 are disposed opposite to each other in a first direction and are respectively located on different sides of the positioning support block in the first direction, thereby restricting the movement of the deeply integrated solid-sealed pole post 31 in the first direction. The output end of the power source 16 is used to connect to the insulating pull rod 32 of the deeply integrated solid-sealed pole post 31, thereby driving the insulating pull rod 32 to move in the first direction. Understandably, the insulating platform 11 is also equipped with a quick-connect clamp 20, which is used to connect to the secondary lead 33 of the deeply fused solid-sealed pole 31, allowing the secondary lead 33 to be easily grounded or connected to test equipment. The quick-connect clamp 20 is arranged adjacent to the bottom limiting block 15 to facilitate the connection of the secondary lead 33, and there is a one-to-one correspondence between the quick-connect clamp 20 and the bottom limiting block 15. When the deeply fused solid-sealed pole 31 is placed on the positioning support block, the extension direction of the insulating pull rod 32 is parallel to the first direction.

[0025] The positioning support block supports the deep-fusion solid-seal pole 31. The inlet end limiting block 14 and the bottom limiting block 15 are arranged opposite each other in the first direction and are located on different sides of the positioning support block in the first direction. They are used to limit the movement of the deep-fusion solid-seal pole 31 toward the inlet end limiting block 14 and toward the bottom limiting block 15 in the first direction, so that the position of the deep-fusion solid-seal pole 31 is fixed. The output end of the power source 16 is connected to the insulating pull rod 32 of the deep-fusion solid-seal pole 31. The output end of the power source 16 drives the insulating pull rod 32 to move closer to the inlet end limiting block 14 in the first direction and applies a certain pressure to the insulating pull rod 32, providing rated contact pressure for loop resistance testing and pressure and simulating the use state for accuracy testing. The output end of the power source 16 drives the insulating pull rod 32 to move away from the inlet end limiting block 14 in the first direction, so that the inlet and outlet circuits of the deep-fusion solid-seal pole 31 are disconnected by a certain distance, providing an opening distance for power frequency withstand voltage and partial discharge testing. This enables the rapid transfer of the deeply integrated solid-sealed pole 31 in various test stages, saving switching time and manpower, and improving test efficiency.

[0026] During the loop resistance test, a certain pressure needs to be applied to the insulating rod 32 of the deeply fused solid-sealed pole 31. At the same time, the inlet stud 34 and outlet stud 35 of the deeply fused solid-sealed pole 31 are connected to the loop resistance tester for testing. At this time, the deeply fused solid-sealed pole 31 is placed on the insulating platform 11 and fixed by the positioning support block. The insulating rod 32 is connected to the output end of the power source 16 and driven to move forward a certain distance, thereby applying a certain pressure to the insulating rod 32 of the deeply fused solid-sealed pole 31 to provide test conditions for the loop resistance test. Then, the clamps of the loop resistance tester are clamped on the inlet and outlet test rows for testing. After the test is completed, the clamps are removed and the power source 16 is reset.

[0027] After the loop resistance test is completed, the entire unit can be directly transported to the next test stage, power frequency withstand voltage and partial discharge test. In this test, the output of the power source 16 drives the insulating pull rod 32 to move in the opposite direction, causing it to move a certain displacement. This disconnects the input and output circuits of the deeply fused solid-sealed pole 31 by a certain distance. The voltage is then connected to the input test bar, and the ground wire is connected to the output test bar. The secondary lead 33 of the deeply fused solid-sealed pole 31 is connected to the quick-connect clamp 20. The quick-connect clamp 20 has a connector that allows the secondary lead 33 of the deeply fused solid-sealed pole 31 to be connected to the ground wire. Then, the power frequency withstand voltage and partial discharge tests can be performed. After the tests are completed, the unit is reset.

[0028] During accuracy testing, the servo motor drives the insulating pull rod 32 to move forward a certain distance, thereby applying a certain pressure to the insulating pull rod 32 to ensure the stable and smooth operation of the inlet and outlet circuits of the deeply fused solid-sealed pole 31. Then, the test line is connected to the inlet and outlet test row, and the secondary lead 33 of the deeply fused solid-sealed pole 31 is connected to the quick-connect clamp 20. The connector of the quick-connect clamp 20 is connected to the circuit board and the test equipment. Then, accuracy tests can be performed, and the device is reset after the test is completed.

[0029] It should be noted that "forward" refers to the direction in which the insulating rod 32 moves the moving contact closer to the stationary contact, and "backward" refers to the direction in which the insulating rod 32 moves the moving contact away from the stationary contact. In other words, "forward" refers to the direction in which the insulating rod 32 moves closer to the inlet end limit block 14 in the first direction, and "backward" refers to the direction in which the insulating rod 32 moves away from the inlet end limit block 14 in the first direction. The power source 16 can be, but is not limited to, a servo motor, a linear motor, etc. When the power source 16 is a servo motor, the output end of the servo motor is connected to the insulating rod 32 through a transmission assembly to convert the rotation of the servo motor into linear motion of the insulating rod 32 in the first direction. The connection between the transmission assembly and the insulating rod 32, and the connection between the output end of the linear motor and the insulating rod 32, can both be made using a fixing pin.

[0030] In one possible implementation, the positioning support block includes an upper positioning support block 12 and a lower positioning support block 13 spaced apart in a first direction. The upper positioning support block 12 supports the upper outer shell of the deep-fusion sealed electrode post 31, and the lower positioning support block 13 supports the lower outer shell of the deep-fusion sealed electrode post 31, effectively dispersing stress. Simultaneously, the spacing between the upper and lower positioning support blocks 12 and 13 improves the stability of the support for the deep-fusion sealed electrode post 31, preventing the deep-fusion sealed electrode post 31 from tilting and causing the extension direction of the insulating pull rod 32 to tilt relative to the first direction. Both the upper and lower positioning support blocks 12 and 13 are made of nylon.

[0031] In one possible implementation, a first limiting groove 17 is provided on the top of the upper positioning support block 12. The first limiting groove 17 penetrates the upper positioning support block 12 in a first direction. The first limiting groove 17 is used to fit against the outer wall of the upper shell to limit the movement of the deep fusion sealing pole 31 in a second direction. Specifically, the outer wall of the upper shell is at least partially located in the first limiting groove 17 to limit the translation of the upper shell in the second direction.

[0032] The top of the lower positioning support block 13 is provided with a second limiting groove 18. The second limiting groove 18 penetrates the lower positioning support block 13 in the first direction. The second limiting groove 18 is used to fit against the outer wall of the lower shell. Specifically, the outer wall of the lower shell is at least partially located in the second limiting groove 18 to limit the translation of the lower shell in the second direction. The second limiting groove 18 corresponds one-to-one with the first limiting groove 17 in the first direction to jointly ensure the stable position of the deep fusion solid seal pole 31.

[0033] To prevent the first limiting groove 17 from directly contacting the upper outer shell and the second limiting groove 18 from directly contacting the lower outer shell, which could cause wear or collision, the inner wall of the first limiting groove 17 is provided with a first buffer pad, and the inner wall of the second limiting groove 18 is provided with a second buffer pad. The first and second buffer pads can be fixed by, but are not limited to, adhesive bonding. There are multiple first limiting grooves 17 and multiple second limiting grooves 18. Multiple first limiting grooves 17 are evenly arranged along the second direction on the upper positioning support block 12, and multiple second limiting grooves 18 are evenly arranged along the second direction on the lower positioning support block 13, for the simultaneous fixing of multiple deep-fusion solidified pole posts 31 and subsequent testing.

[0034] In one possible implementation, the inlet end limiting block 14, the bottom limiting block 15, the first limiting groove 17, and the second limiting groove 18 correspond one-to-one, and the corresponding inlet end limiting block 14, the bottom limiting block 15, the first limiting groove 17, and the second limiting groove 18 are linearly distributed in the first direction. A set of corresponding inlet end limiting blocks 14, the bottom limiting block 15, the first limiting groove 17, and the second limiting groove 18 are used to support and limit a deep fusion solid-sealed pole post 31. A third buffer pad can also be provided on the side of the inlet end limiting block 14 and the bottom limiting block 15 facing each other to avoid the inlet end limiting block 14 and the bottom limiting block 15 directly contacting the deep fusion solid-sealed pole post 31 and causing wear or collision. Furthermore, in some embodiments, the inlet end limiting block 14 and the bottom limiting block 15 are configured to move relative to the insulating platform 11 in a first direction and to lock after moving into place, so as to ensure the limiting effect of the inlet end limiting block 14 and the bottom limiting block 15 on the movement of the deep fusion solid-sealed pole 31 in the first direction. At the same time, the distance between the inlet end limiting block 14 and the bottom limiting block 15 in the first direction can be adjusted to adapt to various models of deep fusion solid-sealed pole 31.

[0035] In one possible implementation, a bracket 19 is provided between the power source 16 and the insulating platform 11. The bracket 19 is located on the side of the bottom limiting block 15 opposite to the inlet limiting block 14. The bracket 19 corresponds one-to-one with the power source 16 and one-to-one with the bottom limiting block 15. The bracket 19 is detachably connected to the insulating platform 11 and detachably connected to the housing of the power source 16, thereby stabilizing the position of the power source 16 relative to the insulating platform 11. One power source 16 is used to test one deep fusion solid-sealed pole 31 at a time. Multiple power sources 16 spaced apart in the second direction can be set up to test multiple deep fusion solid-sealed poles 31 simultaneously, improving testing efficiency.

[0036] In one possible implementation, a movable frame 21 is connected to the bottom of the insulating platform 11, and the bottom of the movable frame 21 is equipped with casters 22. Specifically, the movable frame 21 includes a first vertical rod extending in the height direction, a first horizontal rod connected to two corresponding first vertical rods in a first direction, and a second horizontal rod connected to two corresponding first vertical rods in a second direction. The first and second horizontal rods are used to stabilize the position of the first vertical rods. The casters 22 are installed at the bottom of the first vertical rods for the movement of the movable frame 21 and the insulating platform 11 as a whole. The casters 22 can be, but are not limited to, casters with brakes. The movable frame 21 is made of non-metallic material.

[0037] It should be noted that in this specification, relational terms such as first and second are used only to distinguish one entity from several other entities, and do not necessarily require or imply any such actual relationship or order between these entities.
