Description

Technical Field

[0001] The invention relates to the field of electromagnetic mutual inductor accessories, in particular to an insulating shed component suitable for multi-directional wiring. Background Art

[0002] Insulating sheds are important components of power equipment such as insulators, transformers, and mutual inductors. When used in conjunction with mutual inductors, insulating sheds need to be connected to different types of terminal blocks according to actual needs. However, in practice, traditional mutual inductors and related devices such as insulating sheds often have a relatively simple wiring method, which makes their use and connection inconvenient.

[0003] For example, in the Chinese utility model patent application number 202020434593.3, a composite insulation shed leakage current test device is provided. The test probe is adsorbed by a magnet so that the probe is close to the surface of the shed. The test process is stable and not prone to deviation. The test results are reliable. However, the connection method of this technical solution is still single, which leads to limitations in its use and connection. Summary of the invention

[0004] In order to overcome the defects of the above-mentioned traditional technology, the present invention proposes an insulating shed assembly suitable for multi-directional wiring.

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

[0006] An insulating shed assembly adaptable to multi-directional wiring comprises a lower mainframe box and a plurality of insulating shed bodies; a wiring device is arranged on the upper part of each insulating shed body; the lower mainframe box is connected to a central axis via a bearing, a rotating frame is installed on the upper part of the central axis, and the insulating shed bodies are installed on the rotating frame in a ring-shaped distribution manner; a replacement control assembly is arranged at the lower part of the central axis; the lower mainframe box is connected to a high cover frame, and a wiring disassembly assembly assembly and a line changing device are respectively installed on the high cover frame.

[0007] The wiring device is used to connect the insulating shed body to the outside. Providing multiple insulating shed bodies facilitates replacement during use. An assembly panel is provided on the right side of the lower main box so that the lower main box can be installed on the left side of the transformer housing during use. The rotation of the center axis and the rotating frame facilitates the rotation and replacement of the insulating shed body. The replacement control component is used to fix the replaced center axis and all insulating shed bodies. The wiring disassembly and assembly component is used to remove the wiring on the insulating shed body in use, and the replacement control component controls the wiring head to connect the insulating shed body. The insulating shed body installed on the right side of the rotating frame is in use.

[0008] As a further improvement of the present invention, the replacement control assembly is composed of a balance turntable installed at the bottom of the rotating frame, a side sleeve installed on the lower main box, a No. 1 spring installed in the side sleeve, and a kingpin connected to the No. 1 spring; the kingpin is L-shaped. When replacing, it is necessary to manually pull the kingpin forward and manually rotate the central axis. The upper end of the lower main box has a slide groove that allows the upper part of the kingpin to slide.

[0009] As a further improvement of the present invention, pin holes matching the main pin are evenly distributed on the balance turntable; the main pin is slidably mounted on the side sleeve. That is, each time the central axis is rotated to replace the insulating shed body, the main pin will automatically engage in the appropriate pin hole under the action of elastic force, completing the positioning of the insulating shed body after replacement.

[0010] As a further improvement of the present invention, each wiring device includes a docking wire barrel installed on the upper end of the insulating shed body, and a side extension groove is also provided on the upper part of the docking wire barrel; the wiring device also includes a No. II spring installed in the side extension groove and a clamping block connected to the No. II spring. The interior of the docking wire barrel is used for external connection terminals. The clamping block is used to fix after wiring to prevent the wire ends from falling off.

[0011] As a further improvement of the present invention, the positioning block is slidably installed in the side extension groove, a round handle is provided on the upper end of the positioning block, and a positioning bevel is provided on the side of the positioning block close to the center of the docking barrel. The end of the positioning block away from the II spring and the positioning bevel are both located in the docking barrel in normal state to facilitate fixing the joint.

[0012] As a further improvement of the present invention, the wiring assembly and disassembly assembly comprises a three-axis cylinder mounted on the high cover frame and a release block connected to the three-axis cylinder. The release block can move forward and backward under the drive of the three-axis cylinder.

[0013] As a further improvement of the present invention, the release block is provided with a front bevel matched with the round handle. When the release block is pushed forward, the front bevel will squeeze the round handle, causing the positioning block to slide toward the left, thereby releasing its fixation on the joint.

[0014] As a further improvement of the present invention, the line changing device comprises a lower guide rail mounted on the high cover frame, a placement seat slidably mounted on the lower guide rail, and a hydraulic cylinder connected to the placement seat, wherein the hydraulic cylinder is mounted on the high cover frame. That is, the placement seat can be raised and lowered under the drive of the hydraulic cylinder to facilitate the subsequent installation and removal of the joint.

[0015] As a further improvement of the present invention, the line changing equipment also includes a motor installed on the placement seat, a main socket connected to the motor, and a number of taps installed at the lower end of the main socket, and each tap is provided with two oblique slots adapted to the card bevel at the bottom. The taps are wiring connectors of various types, which are connected to the insulating umbrella skirt body according to actual needs. Each oblique slot is also an inclined surface on one side close to the axis of the tap. Secondly, the two oblique slots are adjacent to each other up and down, and the lowermost oblique slot is connected to the lower end surface of the tap. When the corresponding tap is controlled to move downward and inserted, the end of the card block away from the II spring and the card bevel will be squeezed to insert into the second oblique slot from bottom to top, completing the fixation of the tap.

[0016] As a further improvement of the present invention, the taps are evenly distributed in a ring shape to facilitate the rotation and replacement of the taps. An external terminal is also installed on the main socket. The external terminal is used to connect an external transmission line source.

[0017] The beneficial effects of the present invention are as follows: the present invention can assist in the replacement and use of insulating sheds, the operation is relatively labor-saving, and different taps can be automatically connected, disassembled and replaced with the insulating sheds, thereby realizing the function of multi-directional wiring; the insulating sheds and the taps are relatively tightly connected in the wiring state, and the reliability is high.
