Description

Technical Field

[0001] The present invention relates to the technical field of electrical circuit connection devices, and in particular to a universal electrical circuit conformal connection device for rotating parts with flexible constant pressure. Background Art

[0002] In many electrical work scenarios, it is often necessary to maintain good contact between two electrical components or two contacts, such as between a static component and a rotating component, between a conventional joint component and a special-shaped structural component. Sometimes the two components need to be in long-term stable contact, and sometimes only temporary contact is required. At the same time, the voltage, current, and time required for the work are also different. Due to the complexity and diversity of the above contact states, insufficient contact area, insufficient clamping force, insufficient stability (components are in a rotating state or mechanical vibration occurs), and irregular shapes that cannot be clamped often occur in actual on-site work. In on-site work, the actual results of electrical work often deviate greatly from the expected goals due to unsatisfactory contact conditions. Such as the following work scenarios:

[0003] In the first case, when conducting electrical tests such as AC impedance test on generator rotor winding under dynamic conditions and repeated pulse method inter-turn short-circuit test, the rotor is in a rotating state with a speed ranging from 0-3000r / min. An AC current of several milliamperes to hundreds of amperes or a pulse voltage signal of several millivolts must be applied to the outer surface of the cylindrical rotor slip ring. At this time, general tester clamps and terminal blocks cannot form good contact with the cylindrical slip ring surface.

[0004] In the second case, during the operation of generators and motors, the bearing grounding carbon brushes often jump and spark, resulting in poor grounding of the main shaft, and then causing problems such as increased shaft voltage and increased shaft current. The common cause is the unreasonable setting of the grounding carbon brush holder and the unreasonable structure of the brush holder. To solve the above problems, it is often necessary to use the opportunity of shutdown and maintenance to transform the equipment, so it cannot be solved immediately. What's more, the problem is still not completely solved after a shutdown. Therefore, it is necessary to study a device that can form a parallel circuit with the grounding carbon brush when the grounding carbon brush has problems such as jumping and sparking and cannot be quickly solved, so as to ensure good grounding of the main shaft and avoid the generation of shaft voltage and shaft current.

[0005] In the third case, temporary grounding is often required in on-site electrical work, which is divided into working grounding, protective grounding, lightning protection grounding and shielding grounding according to its function. Temporary grounding measures are often required in on-site operations, including aerial operations. When the grounding body found nearby is in various irregular shapes such as columnar, stepped or wedge-shaped, our grounding elements often do not match its size, or the connection is easy to loosen, and the grounding reliability is poor. Once there is a problem with the grounding, it will cause the equipment to fail to operate normally, the protection to malfunction, the protection to fail, and even a safety accident, and the harm is difficult to estimate. Therefore, it is also very necessary to develop a device that can meet the needs of temporary grounding with rotating parts in various working environments. Summary of the invention

[0006] The purpose of the present invention is to provide a flexible constant-pressure universal electrical circuit conformal connection device for rotating parts, which acts on the soft copper strip connection mechanism through a conformal connection mechanism connected by a soft copper strip connection mechanism and a telescopic component, so that the soft copper strip body on the soft copper strip connection mechanism is in close contact with the rotating part, and at the same time the contact area is increased, and the contacts will not loosen or come off due to mechanical vibrations of the self or the outside world, thereby achieving a stable and reliable connection.

[0068] The conformal connection mechanism 4 comprises an arc-shaped top block 401 , the convex surface of the arc-shaped top block 401 is fixedly connected to the telescopic screw 303 , and convex particles 402 are evenly arranged on the inner side of the concave surface of the arc-shaped top block 401 .

[0069] Furthermore, the concave surface on the arc-shaped top block 401 cooperates with the soft copper belt body 501 to adapt and connect with the rotating component, significantly increasing the contact surface and making the connection more complete. At the same time, it cooperates with the convex particles 402 to prevent displacement between the soft copper belt body 501 and the arc-shaped top block 401, thereby improving the contact stability.

[0070] It also includes a fixing mechanism 6 ; the fixing mechanism 6 is screwed to the outside of the cantilever assembly 1 , and the fixing mechanism 6 is configured to fix and release the cantilever assembly 1 .
