Description

Technical Field

[0001] This utility model relates to the field of wiring clamp technology, and in particular to a wiring clamp for testing high-altitude equipment. Background Technology

[0002] In power systems, substation electrical testing is a crucial step in ensuring the normal operation of electrical equipment. Traditional electrical testing methods mainly include personnel climbing and using boom trucks for wiring and disconnection operations. While both methods have their advantages and disadvantages, they both have significant shortcomings in practical applications:

[0003] Firstly, personnel directly climbing to high places to perform wiring and disconnection operations pose a risk of falling from heights, especially for vertical sleeves, where climbing is extremely difficult and it is almost impossible to complete high-altitude wiring work. The climbing process takes a long time, increasing the overall test time, and also requires a high level of physical strength and technical skills from the operators.

[0004] Secondly, the preparation work for using the boom lift truck (such as fixing, retraction, safety measures, and personnel moving back and forth to the platform) takes a long time, which significantly affects work efficiency. Some boom lift trucks have lifting and extension limit issues, which prevents wiring and disconnection from being completed in one go during on-site testing. The boom lift truck needs to be moved in the middle, which further prolongs the operation time. In addition, some substation transformers are equipped with fire sprinkler brackets, which prevent the boom lift truck from approaching the equipment for wiring, and personnel still need to climb.

[0030] The following detailed description, in conjunction with the accompanying drawings, outlines some embodiments of the present invention. Unless otherwise specified, the following embodiments and features can be combined with each other.

[0031] Please refer to Figures 1-8 This utility model provides a high-altitude equipment test wiring clamp, including an insulating rod 1, an extension rod one 11, an extension rod two 12, a connecting mechanism, an angle conversion mechanism, and a wiring clamp assembly. The tail end of the insulating rod 1 is provided with an insulating handle 13. The insulating rod 1, the extension rod one 11, and the extension rod two 12 can be made of materials such as fiberglass or epoxy resin, which have good insulation performance and are not easily corroded.

[0032] The insulating rod 1, extension rod 11, and extension rod 2 12 are connected by a self-locking mechanism. Depending on the usage height, the insulating rod 1, extension rod 11, and extension rod 2 12 can be used in combination. The insulating rod 1 can be used alone, or the insulating rod 1 can be combined with the extension rod 11, or the insulating rod 1 can be combined with the extension rod 2 12, or the insulating rod 1, extension rod 11, and extension rod 2 12 can be used simultaneously. This allows one set of equipment to meet the high, medium, and low voltage three-sided wiring requirements of the transformer.

[0033] like Figure 7 As shown, the self-locking mechanism includes a self-locking lower sleeve 2 and a self-locking upper sleeve 23. The self-locking lower sleeve 2 is installed at the front end of the insulating rod 1, extension rod 11 and extension rod 22 respectively, and the self-locking upper sleeve 23 is installed at the tail end of extension rod 11 and extension rod 22 respectively. The self-locking upper sleeve 23 and the self-locking lower sleeve 2 are inserted and engaged to realize the quick assembly and disassembly of the insulating rod 1, extension rod 11 and extension rod 22.

[0034] Meanwhile, a positioning pin 21 is provided inside the self-locking lower sleeve 2, and positioning grooves 24 are provided on both sides of the self-locking upper sleeve 23. When the positioning grooves 24 and the positioning pins 21 are engaged, the threaded sleeve 22 rotatably provided on the outer side of the self-locking lower sleeve 2 is rotated so that the threaded sleeve 22 is connected to the external thread of the self-locking upper sleeve 23, thereby strengthening the connection effect between the two.

[0035] like Figure 1 and Figure 2 As shown, one end of the connecting mechanism and the angle conversion mechanism can be combined with the terminal clamp assembly, and the other end of the connecting mechanism and the angle conversion mechanism can be connected to the insulating rod 1, the extension rod 11, and the extension rod 12, respectively. Currently, the clamping angles of current transformers, voltage transformers, surge arresters, and transformers are different. Therefore, the design of the angle adjustment device must consider the above two angle clamping. Thus, the connecting mechanism and the angle conversion mechanism need to be replaced according to the application scenario.

[0036] Among them, such as Figure 3 As shown, the connecting mechanism includes an upper sleeve connector 3 and a lower sleeve connector 31. The upper sleeve connector 3 is welded to the lower end of the wiring clamp assembly, and the lower sleeve connector 31 is welded to an independent self-locking upper sleeve 23. The lower sleeve connector 31 and this independent self-locking upper sleeve 23 form a connector. When the independent self-locking upper sleeve 23 is inserted into the self-locking lower sleeve 2 of the insulating rod 1 or the extension rod 11 or the extension rod 22, the connector is installed. Then, the upper sleeve connector 3 and the lower sleeve connector 31 are inserted and engaged to complete the installation of the wiring clamp assembly. At this time, the device can be used.

[0037] When using, such as Figure 4 As shown, the connector assembly includes a screw 4, with a sleeve upper connector 3 welded to the lower end of the screw 4. The sleeve upper connector 3 is used to connect with the aforementioned connector. The upper end of the screw 4 is threadedly connected to the clamp body 5. An aluminum alloy tube 54 is provided inside the clamp body 5, and an insulating pad 59 is provided inside the aluminum alloy tube 54 to provide electrical isolation. Rotary grooves 57 are provided on the lower sides of both the aluminum alloy tube 54 and the insulating pad 59. A rotating head 41 fixedly provided at the top of the screw 4 rotates within the two rotating grooves 57. Since the groove inside the sleeve upper connector 3 has sharp edges, and the outer side of the sleeve lower connector 31 also has sharp edges, the screw 4 can be rotated by rotating the insulating rod 1. The screw 4 moves upward with the aluminum alloy tube 54 through the rotating head 41 in the two rotating grooves 57, thus enabling the clamp body 5 to open and close.

[0038] Furthermore, a limiting block 58 is provided on the inner side of the clamp 5, and one side of the insulating pad 59 is slidably connected to the limiting block 58 to limit the aluminum alloy tube 54, so that it can move up and down horizontally and stably.

[0039] like Figure 4 As shown, a voltage terminal is provided on the lower side of the clamp 5 for voltage measurement. The voltage terminal includes a wing screw 52, ​​which passes through the washer 51 and is threaded to the clamp 5. The wing screw 52 is very convenient for tightening and loosening the test wires, and can be tightened without a wrench.

[0040] like Figure 6As shown, a current terminal is provided on one side of the aluminum alloy tube 54. The current terminal includes a wing screw 2 55 that is threaded to the aluminum alloy tube 54, and a hexagonal nut 1 53 is provided on the wing screw 1 52, and a hexagonal nut 2 56 is provided on the wing screw 2 55. This makes the voltage and current terminals more secure and less likely to fall off when connecting and disconnecting at heights.

[0041] like Figure 2 and Figure 8 As shown, when it is necessary to change the operating angle, an angle conversion mechanism is installed. The angle conversion mechanism includes a fixed base 6. A bevel gear 61 is rotatably mounted on the lower side of the fixed base 6. A self-locking upper sleeve 23 is connected to the rotating shaft of the bevel gear 61. The self-locking upper sleeve 23 can be connected to the self-locking lower sleeve 2 at the front end of the insulating rod 1, the extension rod 11, and the extension rod 22.

[0042] A second bevel gear 62 is rotatably mounted on the side wall of the fixed base 6. A lower sleeve connector 31 is connected to the shaft of the second bevel gear 62. The lower sleeve connector 31 can be connected to the upper sleeve connector 3 welded to the lower end of the screw 4. By meshing the first bevel gear 61 with the second bevel gear 62, the angle of the wiring clamp assembly can be changed.

[0043] In summary, the working principle of the high-altitude equipment test wiring clamp of this utility model embodiment is as follows: the self-locking mechanism enables the rapid assembly of the insulating rod 1, extension rod 11 and extension rod 2 12, which can meet the needs of different height scenarios. It can not only realize high-altitude wiring, but also allow testers to rotate the wiring by hand, so that one device can meet the wiring of the high, medium and low sides of the transformer. By replacing the connection mechanism and the angle conversion mechanism, it can be flexibly adjusted according to the height and angle of different equipment, ensuring that one device is suitable for multiple wiring scenarios.

[0044] The above are merely preferred embodiments of this utility model and are not intended to limit the scope of this utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
