Description

Technical Field

[0001] The present application relates to the technical field of busbar insulation detection, and in particular to a device for detecting the insulation status of a busbar. Background Art

[0002] The tubular busbar is an important power transmission equipment in the power system, which is widely used in various electrical engineering and high-voltage power distribution systems, especially in high-voltage substations, distribution rooms, industrial plants and underground power tunnels. The tubular busbar is usually made of copper or aluminum alloy materials, has a large current carrying capacity, and can efficiently transmit electrical energy. Its exterior is usually coated with insulating materials to ensure the safe transmission of current and prevent short circuits, electric shocks and other dangers in power equipment. In addition, the tubular busbar plays an important role in current distribution, connection and protection in the power system, and the integrity of its insulation layer is directly related to the stable operation of the power system and the safety of personnel.

[0003] The insulation status detection of tubular busbars currently relies mainly on visual inspection, electrical inspection, and ultrasonic inspection. Visual inspection uses a camera or optical sensor to scan the busbar surface, which can identify obvious surface defects such as cracks and scratches, but is insufficient for detecting minor or deep damage. Electrical inspection evaluates insulation performance by measuring insulation resistance. Although it can detect resistance anomalies, it can only detect surface or near-surface damage and cannot fully evaluate deep defects. Ultrasonic testing identifies cracks or pores by analyzing sound wave reflections. It is suitable for the detection of structural defects, but its ability to detect surface microcracks or minor damage is limited, and the operation is relatively complicated.

[0004] Although common tubular busbar insulation detection technologies can identify defects on the surface or inside of tubular busbars, they still face several problems. First, current detection methods lack efficient continuity and comprehensiveness. Since many detection methods rely on manual operations, it is impossible to quickly and comprehensively detect the tubular busbar throughout the entire process. Secondly, most existing technologies are single detection methods, which cannot comprehensively evaluate multiple types of damage, and lack accurate diagnosis for different degrees of damage, resulting in post-detection processing that is often inefficient or too rough. Finally, existing methods usually rely on manual follow-up processing after defects are discovered, such as marking and repair, which makes the process cumbersome and inefficient, and cannot achieve timely response and accurate repair. Summary of the invention

[0005] In order to improve the efficiency of busbar detection and subsequent processing, the present application provides a busbar insulation status detection device.

[0006] The present application provides a busbar insulation status detection device, which adopts the following technical solution: A detection device for the insulation state of a busbar, used for detecting the surface of the busbar and performing subsequent processing, comprises two sets of semi-cylindrical clamps, the two clamps can be combined to form a complete cylindrical structure, and the connection between the two clamps is magnetically arranged, and the two clamps are provided with: A support and guide mechanism, used for supporting the two clamps after being enclosed, and for driving the two clamps to slide along the length direction of the busbar; An annular groove, wherein the two annular grooves form a complete annular groove when the two hoops are closed together; An annular guide rail, wherein the two annular guide rails form a complete annular guide rail when the two hoops are enclosed, and a sliding seat is slidably engaged on the inner wall of the annular guide rail, and the annular guide rail can drive the sliding seat to perform circular motion; The slide seat is provided with: Inspection mechanism, used to conduct comprehensive inspection of the busbar outer wall for surface defects, insulation performance and structural defects; A marking mechanism, used to evaluate the defects detected by the detection mechanism, when the busbar surface is slightly damaged and does not affect normal use, when the busbar surface is slightly damaged, and when the busbar surface is seriously damaged, the marking mechanism sprays three different color marks to the defective position respectively; A repair mechanism, used for carrying out targeted repairs on the marks of different colors sprayed by the marking mechanism; A display mechanism, installed outside one of the clamps, electrically connected to the detection mechanism, and used to display different degrees of damage to the busbar surface detected by the detection mechanism; A locking mechanism is arranged inside the two clamps and is used to clamp and fix the busbar when the detection mechanism detects slight or severe damage on the surface of the busbar; When the marking mechanism sprays a mark indicating that the busbar surface is slightly damaged, the repair mechanism repairs the damaged position on the busbar surface. When the marking mechanism sprays a mark indicating that the busbar surface is severely damaged, the marking mechanism does not repair and performs manual verification.

[0007] By adopting the above technical solution, when the busbar needs to be inspected, the two clamps are clamped outside the busbar so that the two clamps are enclosed to form a complete cylindrical structure.

At this time, the repair mechanism sprays repair fluid on the mark for repair, and the locking mechanism locks the busbar so that the clamp cannot move along the busbar. When serious damage is detected on the busbar surface, the marking mechanism sprays a mark indicating that no repair is required and manual verification is required. At this time, the locking mechanism will lock the busbar so that the clamp cannot move along the busbar. At this time, the operator can separate the two clamps to manually verify the location of the damage and determine whether it is necessary to immediately shut down the power supply or even directly replace this section of the busbar.

[0048] The liquid storage tank 418 is installed on the mounting seat 411, one end of the air pressure cylinder 417 is connected to the inner cavity of the liquid storage tank 418 and the other end is open, the piston 416 extends from the open end of the air pressure cylinder 417 and is slidably sealed in the inner cavity, a first one-way valve is provided between the air pressure cylinder 417 and the liquid storage tank 418 for the gas and liquid in the air pressure cylinder 417 to flow into the liquid storage tank 418 in one direction, and a second one-way valve is provided on the outer wall of the air pressure cylinder 417 for the external gas and liquid to enter the air pressure cylinder 417 in one direction; The liquid outlet pipe 419 is connected to the liquid storage tank 418 , and the end is arranged opposite to and close to the outer surface of the busbar.

[0049] After the marking mechanism 3 marks, the liquid outlet pipe 419 rotates to a position facing the marking driven by the slide 14. At this time, the driving member 412 works, and the driving member 412 drives the rotating shaft 413 to rotate. The rotating shaft 413 drives the bidirectional threaded rod of the ball screw 414 to rotate, so that the ball sleeve of the ball screw 414 reciprocates along the bidirectional threaded rod, thereby driving the piston 416 to reciprocate through the connecting rod 415. When the piston 416 compresses the space in the air pressure cylinder 417, the paint in the liquid storage tank 418 is sprayed out from the end of the liquid outlet pipe 419, thereby realizing the repair of the required position.

[0050] Reference Figure 4 , Figure 6 and Figure 7 The recovery assembly 42 includes a driving gear 421, a driven gear 422, a recovery bucket 423, a connecting plate 424, a sealing recovery ring 4232 and a recovery pipe 425. The driving gear 421 is coaxially fixed to the rotating shaft 413. A rotary sealing joint is provided between the liquid outlet pipe 419 and the liquid storage bin 418. The liquid outlet pipe 419 is rotary sealed and installed on the rotary sealing joint. The driven gear 422 is coaxially fixed to the liquid outlet pipe 419 and meshes with the driving gear 421. The recovery bucket 423 is funnel-shaped with openings at both ends.

If there is excess repair liquid during repair, when the recovery bucket 423 makes eccentric movement, the bottom of the recovery bucket 423 scrapes the repair liquid, so that the repair liquid enters the annular cavity 4231. As the repair liquid gradually accumulates in the annular cavity 4231, the repair liquid will gradually move upward on the inner wall of the annular cavity 4231, and when it moves to the sealing recovery ring 4232, it enters the sealing recovery ring 4232, and then the repair liquid is recycled through the recovery pipe 425, thereby saving the repair liquid and improving the utilization rate of the repair liquid.

[0053] During the reciprocating motion of the piston 416, when the piston 416 moves away from the air cylinder 417, the piston 416 evacuates the air cylinder 417, so that the excess paint that has entered the annular cavity returns to the recovery pipe 425 through the sealing recovery ring 4232, and enters the air cylinder 417 through the recovery pipe 425. During the movement of the piston 416 toward the air cylinder 417, the paint that has entered the air cylinder 417 is pressed into the liquid storage tank 418, thereby achieving smoothing and recovery of the paint.

[0054] Reference Figure 2 and Figure 3 The locking mechanism 6 includes a telescopic member 61 and a clamping plate 62 arranged at the telescopic end of the telescopic member 61. Multiple groups of telescopic members 61 are arranged corresponding to each clamp 1, and each telescopic member 61 can drive the corresponding clamping plate 62 to clamp and fix the outer wall of the busbar.

[0055] When the sensor detects slight or severe damage on the busbar surface, the telescopic member 61 extends, driving the clamping plate 62 to abut against the outer surface of the busbar, so that the two clamps 1 are locked on the busbar. At this time, automatic repair or manual verification can be performed.

[0056] Reference Figure 1 and Figure 3 The support guide mechanism 7 includes a fixed seat 71 and a guide wheel 72 arranged on the fixed seat 71. There are multiple sets of fixed seats 71 and guide wheels 72, and each fixed seat 71 is installed at intervals on the inner wall of the clamp 1. The guide wheel 72 is rotatably installed on the corresponding fixed seat 71 and can be rotated to abut against the outer wall of the busbar when the clamp 1 moves. The guide wheel 72 can guide the movement of the two clamps 1, so that the two clamps 1 can move on the busbar more easily.

[0057] The implementation principle of a detection device for the insulation status of a busbar in an embodiment of the present application is as follows: when the busbar needs to be detected, two clamps 1 are clamped outside the busbar so that the two clamps 1 are enclosed to form a complete cylindrical structure. At this time, the two clamps 1 are moved along the length direction of the busbar, and the detection mechanism 2 performs rotation detection on the outer surface of the busbar, and the marking mechanism 3 can mark the detected result; When it is detected that the busbar surface has slight damage which does not affect normal use, the marking mechanism 3 sprays a mark indicating that no repair or manual verification is required; When it is detected that the busbar surface is slightly damaged, the marking mechanism 3 sprays a mark indicating that repair is required but no manual verification is required. At this time, the repair mechanism 4 sprays repair fluid on the marked area for repair, and the locking mechanism 6 locks the busbar so that the clamp 1 cannot move along the busbar; When serious damage is detected on the busbar surface, the marking mechanism 3 sprays a mark indicating that no repair is required and manual verification is required. At this time, the locking mechanism 6 will lock the busbar, so that the clamp 1 cannot move along the busbar. At this time, the operator can separate the two clamps 1 to manually verify the location of the damage and determine whether it is necessary to immediately shut down the power supply or even directly replace this section of the busbar.

[0058] The display mechanism 5 can clearly assist in prompting the type of defect detected at this time, so as to prompt the operator whether to continue pushing the clamp 1 forward.

[0059] The present application also discloses a method for detecting the insulation status of a busbar, including the following method: S1: When the busbar needs to be inspected, the two clamps are clamped outside the busbar to form a complete cylindrical structure; S2: Slowly move the two clamps along the length direction of the busbar. The detection mechanism detects the surface and interior of the busbar. When the indicator light is on, stop moving the clamps. If the green light is on, the marking mechanism sprays out a green mark; If the yellow light is on, the marking mechanism sprays a yellow mark, the locking mechanism locks the two clamps on the busbar, and the repair mechanism sprays a repair fluid to repair the yellow mark. When the repair is completed, the locking mechanism stops locking the two clamps on the busbar; If the red light is on, the marking mechanism sprays a red mark, and the locking mechanism locks the two clamps on the busbar. The two clamps are manually separated, and the damage at the red mark is manually inspected to manually check whether it is necessary to immediately shut down the power or replace this section of the busbar; S3: If the yellow light is on, the detection mechanism detects the shape, size and glue amount of the repair liquid at the yellow mark. When the shape, size and glue amount of the repair liquid are detected to be qualified, the marking mechanism sprays a green mark to cover the yellow mark. When any of the shape, size and glue amount of the repair liquid is detected to be unqualified, the repair mechanism performs a second repair on the shape, size and glue amount of the repair liquid at the yellow mark, and repeats this step until the shape, size and glue amount of the repair liquid at the yellow mark are qualified. S4: When the clamp moves to the end of the busbar, the clamp moves in the opposite direction, and the detection mechanism detects the green mark. When it moves to the pure green mark, the detection mechanism continues to move. When the green mixed yellow mark is detected, the locking mechanism is locked. The detection mechanism performs a repair quality inspection on the mixed mark. If the repair quality is qualified, the locking mechanism is unlocked. If the repair quality is unqualified, the green and yellow indicators light up at the same time, and the locking mechanism locks the clamp on the busbar. S5: When the green and yellow lights are on at the same time, separate the clamp, manually check the green and yellow mixed marks, and perform manual repairs.

[0060] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
