[0007] By setting up a spacing adjustment mechanism, when the bevel gear group is rotated externally, the two sets of contact rods can be driven to move toward the center at the same time through the bidirectional lead screw slide, so as to adapt to the electric shock nodes of static VAR generators of different specifications. The detection is highly versatile. After power-on, its battery can normally supply power to the early warning parts. The early warning parts include a buzzer and a flashing light. After the circuit is connected, it will make a sound and flash the light to alert the detection personnel.

[0009] By loosening the hexagonal nut, the bidirectional lead screw slide can be pushed downward along the through slot, thereby changing the heights of the two sets of contact rods, thereby adapting to contact nodes of static VAR generators of different heights, and further improving versatility.

[0010] In a preferred embodiment, the clamping mechanism includes a storage plate arranged at the upper end of the cabinet body, the upper end of the storage plate is slidably connected to a vertical plate, a T-shaped rod is slidably connected inside the vertical plate, a spring is fixedly arranged on one side of the vertical plate near the T-shaped rod, one end of the spring is fixedly arranged on the end of the T-shaped rod, and the other end of the T-shaped rod is fixedly arranged on a clamping plate, a roller is embedded in the clamping surface of the clamping plate, and a toggle mechanism for pushing the vertical plate to move is fixedly arranged on the front part of the two-way screw slide near the upper end of the vertical plate is used to push the vertical plate to move, the vertical plate and the clamping plate are supported in two groups about the central axis of the cabinet body, the toggle mechanism includes a push plate fixedly arranged on the front part of the two-way screw slide near the upper end of the vertical plate, and a hidden groove is opened on the upper end of the storage plate near the lower end of the push plate, and the cross-sectional shape of the push plate is triangular.

[0011] By setting a vertical plate that can be reset after sliding on the storage plate, the bidirectional screw slide will push the push plate when moving downward, against the back of the vertical plate, and slowly push the two sets of clamps closer, so as to clamp static reactive generators of different specifications.

[0012] The utility model provides a detection mechanism for a static VAR generator through improvement, which has the following improvements and advantages compared with the prior art:

[0013] First, by setting a bidirectional screw slide, the distance between the two sets of touch rods can be adjusted when the bevel gear set is turned, and by loosening the locking nut, the bidirectional screw slide can be moved downward to adjust the height of the two sets of touch rods. The two cooperate with each other to detect static VAR generators of different specifications.

[0014] Second, when the bidirectional screw slide moves downward, the push plate moves with it, pushing the two sets of vertical plates to move toward the center at the same time, clamping the static VAR generator between the two sets of clamping plates. During the pushing process, if the static VAR generator has been clamped, the clamping plate will no longer move under the action of the spring, and will not hinder the height adjustment of the touch rod, thereby facilitating the clamping and positioning of the static VAR generator.

[0022] The detection mechanism of a static VAR generator disclosed by the utility model is mainly used in scenarios where it can only detect a static VAR generator of a certain specification and has poor versatility.

The middle part of the two-way screw slide 9 is embedded with a bevel gear set 10, and one end of the bevel gear set 10 passes through the two-way screw slide 9 and is threadedly connected with a hexagonal nut 11; Clamp mechanism: The clamp mechanism is used to clamp and position the static reactive generator. The clamp mechanism is fixedly arranged on the upper end of the cabinet 1. The switch 5, the early warning part 6 and the two sets of touch rods 7 are electrically connected to the battery 4 through wires, and the switch 5, the early warning part 6 and the two sets of touch rods 7 are connected in series with the battery 4.

[0024] In this solution, by setting a bidirectional screw slide 9, when the bevel gear set 10 is turned, the distance between the two sets of contact rods 7 can be adjusted, so that static VAR generators of different specifications can be detected. After contact, a complete power-on circuit is formed. If there is no problem with the internal circuit of the static VAR generator, the early warning component 6 will beep and flash the light to prompt the operator. If there is a problem with the circuit, the early warning component 6 will not work, thereby detecting the static VAR generator.

[0025] Reference Figure 1 and Figure 4In a preferred embodiment, the height adjustment member includes a threaded rod 12 arranged at the other end of the bidirectional screw slide 9, a through groove 13 is opened on one side of the vertical frame 2 close to the threaded rod 12, one end of the threaded rod 12 is connected to the through groove 13, and a hexagonal nut 11 is threadedly connected to the threaded rod 12 close to the side of the through groove 13; by loosening the hexagonal nut 11, the bidirectional screw slide 9 can be pushed downward, the height of the two sets of touch rods 7 can be changed, and the versatility of detection can be further improved.

[0026] Reference Figure 1 and Figure 3 In a preferred embodiment, the clamp mechanism includes a storage plate 15 arranged at the upper end of the cabinet 1, and a vertical plate 16 is slidably connected to the upper end of the storage plate 15, and a T-bar 17 is slidably connected inside the vertical plate 16. A spring 18 is fixedly arranged on one side of the vertical plate 16 near the T-bar 17, and one end of the spring 18 is fixedly arranged at the end of the T-bar 17, and a clamping plate 19 is fixedly arranged on the other end of the T-bar 17. The clamping surface of the clamping plate 19 is embedded with a roller 20, and a toggle mechanism for pushing the vertical plate 16 to move is fixedly arranged at the front of the two-way screw slide 9 near the upper end of the vertical plate 16, and two groups of vertical plates 16 and clamping plates 19 are arranged to support each other about the central axis of the cabinet 1.

[0027] Specifically, the clamping mechanism is capable of clamping STATCOMs of different specifications through the spring 18, and after clamping, the STATCOM is located in the middle position, corresponding to the two groups of contact rods 7, and when the STATCOM is pushed so that the contact node contacts the two groups of contact rods 7, the roller 20 can effectively reduce the friction between the clamping plate 19 and one side of the STATCOM.

[0029] It should be noted that, during the downward movement of the bidirectional screw slide 9, its push plate 21 moves along with the movement of the bidirectional screw slide 9, and the vertical plate 16 contacts the inclined surface of the push plate 21 and is slowly pushed, thereby clamping the static reactive generator.

[0030] Working principle: When in use, place the static reactive generator between the two groups of clamping plates 19, manually rotate the bevel gear set 10 according to the spacing of the static reactive generator's contact nodes, adjust the spacing between the two groups of contact rods 7, and then loosen the locking nut 14, move the bidirectional screw slide 9 downward until the height of the two groups of contact rods 7 is the same as the height of the contact nodes of the static reactive generator, and the two cooperate with each other, so that static reactive generators of different specifications can be detected, and the versatility is strong. When the bidirectional screw slide 9 moves downward, the push plate 21 moves along, pushing the two groups of vertical plates 16 to move toward the center at the same time, clamping the static reactive generator between the two groups of clamping plates 19. During the pushing process, if the static reactive generator has been clamped, after pushing, the clamping plate 19 will no longer move under the action of the spring 18, and will not hinder the height adjustment of the contact rod 7.

[0031] The above are only preferred specific implementations of the utility model, but the protection scope of the utility model is not limited to them. The replacement can be a replacement of part of the structure, device, method steps, or a complete technical solution. Equivalent replacement or changes based on the technical solution of the utility model and its utility model concept should be included in the protection scope of the utility model.
