Description

Technical Field

[0001] This utility model belongs to the technical field of cable partial discharge locating device, and particularly relates to a cable partial discharge locating device. Background Technology

[0002] Cable partial discharge locating devices use sensors installed on the cable to capture signals such as electrical pulses, electromagnetic waves, and ultrasonic waves generated by partial discharge in real time. After processing and analysis, these signals can accurately determine the location, intensity, and type of partial discharge, providing maintenance personnel with precise fault location information, thereby quickly finding and repairing the fault point.

[0003] Most cable partial discharge locating devices have several drawbacks in use. For example, they can only be fixed to one part of the cable. When other parts of the cable need to be inspected, the entire device must be disassembled and repositioned, which is complex and time-consuming. Furthermore, most locating devices can only locate one cable at a time, not multiple cables simultaneously. Workers must inspect multiple cables sequentially, resulting in low inspection efficiency. Therefore, we propose a cable partial discharge locating device. Utility Model Content

[0004] The purpose of this invention is to provide a cable partial discharge locating device to solve the problems mentioned in the background art.

[0005] In view of this, the present invention provides a cable partial discharge locating device, comprising:

[0006] The housing has two rollers rotatably mounted inside it, and a fixing block is fixedly mounted inside the housing between the two rollers. A sliding groove is provided inside the housing, and a sliding plate is slidably mounted in the sliding groove. Two rollers are rotatably mounted on one side of the sliding plate, and a fixing block is fixedly mounted on one side of the sliding plate between the two rollers. A threaded rod is rotatably mounted inside the sliding groove on the other side of the sliding plate, and one end of the threaded rod passes through the sliding plate and is threadedly connected to the sliding plate.

[0007] A drive assembly, located within the housing, for driving the threaded rod to rotate;

[0008] Two limiting strips are fixedly installed on one side of the housing. Two limiting grooves are opened on the other side of the housing. The two limiting strips are respectively inserted into the two limiting grooves. A discharge detection head is fixedly installed inside the housing and between the first fixed block and the second fixed block.

[0009] A fixing component, located within the housing, is used to limit the position of the housing.

[0010] In this technical solution, when the cable needs to be positioned, the housing is first placed on the cable. The drive assembly can drive the threaded rod to rotate. Under the action of the thread, the threaded rod drives the sliding plate to slide towards the first roller. When the sliding plate slides to the appropriate position, the first and second fixing blocks will clamp the cable. When it is necessary to position the cable to other positions, the operator only needs to pull the housing. At the same time, the two first rollers and the two second rollers will rub against the cable and rotate, ensuring that the housing slides smoothly on the cable. This makes it convenient for the operator to position the housing to any position on the cable. Finally, the discharge detection head contacts the cable and can detect whether the cable has partial discharge.

[0011] When multiple cables need to be positioned simultaneously, the two limiting strips on one housing are inserted into the two limiting slots on the other housing. Then, one housing can only slide up and down on one side of the other housing, but cannot slide left and right. The fixed components can fix the position of the two housings, making it convenient for personnel to position multiple cables at the same time.

[0012] In the above technical solution, the driving component further includes:

[0013] A worm gear is fixedly installed at the other end of a threaded rod. A worm is meshed on one side of the worm gear. The lower end of the worm extends through a sliding groove to the outside. Both the worm gear and the worm are rotatably connected to the sliding groove.

[0014] In this technical solution, when it is necessary to position the cable, the housing is first placed on the cable, and then the worm is rotated. The worm drives the worm wheel that meshes with it to rotate, and the worm wheel drives the threaded rod to rotate. Under the action of the thread, the threaded rod drives the sliding plate to slide towards the roller one. When the sliding plate slides to the appropriate position, the fixing block one and the fixing block two will clamp the cable.

[0015] In the above technical solution, the fixing component further includes:

[0016] The second sliding groove is formed inside the housing. A sliding block is slidably installed inside the second sliding groove. Several springs fixed to the inner wall of the second sliding groove are fixedly installed on one side of the sliding block. The other side of the sliding block passes through the second sliding groove and extends to the outside. The other side of the sliding block is inserted into the housing. The upper end of the sliding block passes through the second sliding groove and extends to the outside.

[0017] In this technical solution, when multiple cables need to be positioned simultaneously, firstly, the sliding block on one of the housings is pulled towards the spring, while several springs are compressed and contracted. After the other side of the sliding block is fully inserted into the sliding groove, the two limiting strips on one of the housings are then inserted into the two limiting grooves on the other housing. Then, one housing can only slide up and down on one side of the other housing, but cannot slide left and right. At this point, the sliding block is released, and under the action of the rebound force of several springs, the sliding block slides away from the spring. Subsequently, the sliding block on one housing is inserted into the other housing, which can fix the position of the two housings, making it convenient for personnel to position multiple cables simultaneously.

[0018] In the above technical solution, furthermore, an operating disc is fixedly installed at the lower end of the worm gear.

[0019] In this technical solution, the worm gear is easily rotated via a control panel.

[0020] In the above technical solution, furthermore, anti-slip rubber pads are fixedly installed on the sides of the fixing block one and the fixing block two that are close to each other.

[0021] In this technical solution, when both anti-slip rubber pads are in close contact with the cable, it can be ensured that the housing will not move easily on the cable.

[0022] In the above technical solution, further, guide posts are fixedly installed in the sliding groove on both sides of the threaded rod, one end of each guide post penetrates the sliding plate, and both guide posts are slidably connected to the sliding plate.

[0023] In this technical solution, the sliding plate slides on two guide posts, which can ensure the stability of the sliding plate.

[0024] In the above technical solution, the cross-section of the limiting strip is trapezoidal.

[0025] In this technical solution, after the two limiting strips on one housing are inserted into the two limiting grooves on the other housing, the one housing can only slide up and down on one side of the other housing, and cannot slide left and right.

[0026] The beneficial effects of this utility model are:

[0027] 1. This cable partial discharge positioning device first places the housing on the cable. Through the set drive component, the threaded rod can be driven to rotate. Under the action of the thread, the threaded rod drives the sliding plate to slide towards the first roller. When the sliding plate slides to the appropriate position, the first and second fixing blocks will clamp the cable. When it is necessary to position the cable to other positions, the operator only needs to pull the housing. At the same time, the two first rollers and the two second rollers will rub against the cable and rotate, ensuring that the housing slides smoothly on the cable, making it convenient for the operator to position the housing to any position on the cable.

[0028] 2. When multiple cables need to be located simultaneously, the cable partial discharge positioning device inserts two limiting strips on one housing into two limiting grooves on the other housing. Then, one housing can only slide up and down on one side of the other housing, but cannot slide left and right. The fixed components can fix the position of the two housings, making it convenient for personnel to locate multiple cables at the same time. Attached Figure Description
