Description

Technical Field

[0001] The present invention relates to a transposed conductor for an ultra-high voltage reactor and a use process thereof, in particular to a transposed conductor for an ultra-high voltage reactor and a use process thereof. Background Art

[0002] Ultra-high voltage reactors, a type of reactor, primarily convert and store high-voltage electrical energy into magnetic energy. These reactors require transposed conductors, the most common use of which is wrapping around the reactor coils.

[0003] To speed up the manufacturing of reactors, the transposed conductors are usually wound directly around the corresponding reactor coils before the reactor components are assembled. However, in actual manufacturing, due to the large number of transposed conductors required for the winding, traditional manual operations and single mechanical winding methods are difficult to complete quickly. Summary of the Invention

[0004] In order to improve and speed up the efficiency of winding a transposed conductor, the present invention proposes a transposed conductor for an ultra-high voltage reactor and a process for using the same.

[0005] The technical problem to be solved by the present invention is achieved by adopting the following technical solutions:

[0006] Transposed conductors for UHV reactors consist of horizontally arranged single copper conductors, each with a grease pad placed at its lower end. The copper conductors and grease pads are covered with an insulating rubber layer. The copper conductors have excellent electrical conductivity. An enamel layer can be placed between the insulating rubber layer and the copper.

[0007] The process for using transposed conductors for UHV reactors is based on a synchronous retraction device for transposed conductors. The device consists of a retraction base, an elevator mounted on the retraction base, a platform connected to the elevator, several annular covers mounted on the platform, a surrounding drive assembly connected to the annular covers, and several auxiliary clamping assemblies that cooperate with the surrounding drive assemblies. The elevator is used to drive the platform and annular covers to move upward and downward. The auxiliary clamping assembly is used to secure the reactor coil, and the surrounding drive assembly is used to drive the transposed conductors for auxiliary winding.

[0008] Furthermore, circular positioning sleeves are evenly distributed horizontally on the retraction base, each housing a reactor coil for winding the transposed conductors. The circular positioning sleeves are used to position the reactor coils, around which the transposed conductors are wound.

[0009] Further, the circular positioning sleeve is located directly below the corresponding ring cylinder cover in a one-to-one correspondence manner.

[0010] Further, the lifter is composed of a No. I motor installed on the folding base, a lead screw connected to the No. I motor, and a double guide frame vertically slidingly installed with the high platform plate; the double guide frame is installed on the folding base, and the lead screw is connected to the high platform plate. Under the transmission action of the lead screw nut, the high platform plate and each ring cylinder cover can be lifted to facilitate the control of the ring cylinder cover being sleeved on the upper part of each reactor coil.

[0011] Further, the surrounding driving assembly is composed of a central shaft connected to the upper end of each ring cylinder cover, a belt pulley installed on each central shaft in a corresponding manner, a belt connecting all the belt pulleys, and a No. II motor connected to any one central shaft. The central shaft and each corresponding ring cylinder cover are coaxially arranged. Under the driving of the No. II motor and the transmission action of the belt, each ring cylinder cover can be rotated.

[0012] Further, the high platform plate is installed with a rear bracket for fixedly installing the No. II motor; all the central shafts are installed on the rear bracket through bearing seats. This structure is a conventional design for fixed installation.

[0013] Further, each auxiliary clamping assembly is composed of a large ring gear installed on the corresponding central shaft through a bearing, a spur gear engaged with the large ring gear, and a No. III motor connected to the spur gear; the No. III motor is installed on the high platform plate. That is, the driving of the No. III motor and the gear transmission can drive each large ring gear to rotate.

[0014] Further, each ring cylinder cover is uniformly provided with three through grooves in the annular direction; each auxiliary clamping assembly further includes a retractable rod slidingly installed at each through groove, an arc-shaped soft pad connected to each retractable rod, and a high protruding rod connected to the retractable rod. The above structure can clamp and fix the upper part of the reactor coil through the sliding of the retractable rod.

[0015] Further, each large ring gear is uniformly provided with three radial arc grooves in the annular direction, and the high protruding rod is slidingly matched with the corresponding radial arc groove. Through the rotation of the large ring gear, the retractable rod can be driven to slide, thereby completing the clamping and fixing work.

[0016] The beneficial effects of the present application are:

[0017] The present application can assist in winding the transposed conductor around the reactor coil in a highly automated manner, saving manpower, and can also control the winding work of multiple groups of transposed conductors to be performed synchronously, which is not only convenient to control, but also effectively improves the efficiency of winding the transposed conductor.

[0029] As shown in the figure, Figure 2 and Figure 3 The folding base 1 is uniformly installed with a circular positioning sleeve 4 in the horizontal direction, and each circular positioning sleeve 4 is placed with a reactor coil 19 for winding the transposed conductor. The circular positioning sleeve 4 is used to position the reactor coil 19, and the final transposed conductor needs to be wound on the reactor coil 19.

[0030] As shown in the figure, Figure 4 The circular positioning sleeve 4 is located directly below the corresponding ring cylinder cover 3 in a one-to-one correspondence. That is, the ring cylinder cover 3 can be respectively sleeved on the upper part of each reactor coil 19.
