Technical Field
[0001] This utility model relates to the field of insulation protection, and in particular to an insulation protection device for high-voltage generator units. Background Technology
[0002] High-voltage generator insulation protection devices are important devices used to protect high-voltage equipment and personnel safety. They primarily work by isolating high-voltage current and preventing electric arcing where current should not flow, thus avoiding safety accidents.
[0003] Commonly used insulating protective components in high-voltage generator sets include insulators, insulating bushings, insulating tubes, and insulating suspensions. These components should be adapted to various conductive elements in the high-voltage generator set. Regarding insulating bushings, the patent announcement number CN206194466 U describes an improvement to the connection between two insulating bushing sections. Specifically, it includes a threaded interface and a connecting flange at the end of the insulating bushing, making installation and connection more convenient and robust.
[0004] However, the following defects and shortcomings still exist in the application implementation process:
[0005] The stud is inserted into the inside of the tube and then reinforced by a threaded connection. This results in the inner diameter of the stud being smaller than the inner diameter of the tube. Therefore, when threading cables or other conductive components, the stud may come into contact with the end of the stud, affecting the threading of the cables. At the same time, the disassembly and assembly operations are relatively cumbersome.
[0006] Therefore, it is necessary to provide a new high-voltage unit insulation protection device to solve the above-mentioned technical problems. Utility Model Content

[0008] The high-voltage unit insulation protection device provided by this utility model includes an insulating sleeve body, and a connecting pipe is inserted and installed at the end of the insulating sleeve body.
[0009] The connecting pipe has slots on its inner circumference and at its end. The insulating sleeve body is inserted into the slot, so that the inner diameter of the insulating sleeve body and the connecting pipe are the same.
[0010] A locking assembly is also installed on the connecting pipe. The locking assembly consists of an adjusting part and multiple engaging parts. The multiple engaging parts are distributed in a ring shape on the outside of the insulating sleeve body and can contact and squeeze the insulating sleeve body.
[0011] A positioning element is also installed on the connecting pipe, which can be engaged with the adjusting part.
[0012] Preferably, the adjusting part includes a plurality of positioning plates arranged in a ring and welded to the outer wall of the connecting pipe. A groove is provided on one side of the positioning plate along the radial direction of the connecting pipe, and a first slide channel penetrating the positioning plate is provided at the bottom of the inner side of the groove.
[0013] A concentrically arranged positioning cylinder is rotatably connected to the outside of the connecting pipe. An adjustment plate close to the positioning plate is welded and fixed to one end of the positioning cylinder. A second slide is provided on the side of the adjustment plate facing the positioning plate, corresponding to the number and position of the first slide and set at an inclination.
[0014] Preferably, an arc-shaped plate is welded and fixed to the outer circumference of the positioning cylinder, and the outer circumference of the arc-shaped plate has multiple ring-shaped slots.
[0015] Preferably, the engagement part includes a slide block, which is embedded and slidably connected inside the slide groove. A drive pin is vertically welded to one side of the slide block, which passes through the first slide rail and extends into the second slide rail. A rubber block that can contact the insulating sleeve body is also bonded and fixed to the other side of the slide block.
[0016] Preferably, the positioning component includes a fixing frame, which is welded and fixed to the outer circumference of the connecting pipe. A locking rod is rotatably connected to the fixing frame, and a torsion spring that abuts against the fixing frame is also fixed on the locking rod.
[0017] Preferably, under normal conditions, the spring force of the torsion spring causes the locking rod to be embedded and fixed inside the bayonet.
[0018] Compared with related technologies, the high-voltage generator insulation protection device provided by this utility model has the following beneficial effects:
[0019] This utility model provides an insulation protection device for high-voltage generator sets, in which the insulating sleeve body is inserted into the connecting pipe to make their inner diameters consistent, which makes it more convenient to lay cables.

[0030] The specific implementation of this utility model will be described in detail below with reference to specific embodiments.
[0031] Please see Figures 1 to 5The present invention provides a high-voltage generator insulation protection device, which includes an insulating sleeve body 1 and a connecting pipe 2 inserted and installed at the end of the insulating sleeve body 1.
[0032] The inner wall of the connecting pipe 2 is provided with slots 21 at the end. The insulating sleeve body 1 is inserted into the slot 21 so that the inner diameter of the insulating sleeve body 1 and the connecting pipe 2 are the same.
[0033] A locking assembly 3 is also installed on the connecting pipe 2. The locking assembly 3 consists of an adjusting part and multiple engaging parts. The multiple engaging parts are distributed in a ring shape on the outside of the insulating sleeve body 1 and can contact and squeeze the insulating sleeve body 1.
[0034] A positioning element 4 is also installed on the connecting pipe 2, which can be engaged with the adjusting part.
[0035] It should be noted that a connecting tube 2 is provided at the end of the insulating sleeve body 1. When connecting the insulating sleeve bodies 1, both insulating sleeve bodies 1 are inserted into the connecting tube 2. At the same time, a slot 21 is provided inside the connecting tube 2 so that when the insulating sleeve body 1 is inserted into the slot 21, its inner diameter can be consistent with the inner diameter of the connecting tube 2. Therefore, it will not be obstructed when laying cables and other conductive components, and the operation is more convenient.
[0036] The locking assembly 3 is used to reinforce the connection between the insulating sleeve body 1 and the connecting pipe 2. It includes an adjusting part and an engaging part. The adjusting part can drive the engaging part to move, so that the engaging part contacts and squeezes the insulating sleeve body 1. There are multiple engaging parts, which are distributed in a ring shape on the outside of the insulating sleeve body 1. Therefore, the limiting effect of the insulating sleeve body 1 is better, and the connection between the two is more secure.
[0037] The positioning element 4 is provided for the adjustment part in the locking assembly 3. That is, when the engagement part and the insulating sleeve body 1 are in close contact, the positioning element 4 is used to lock the adjustment part. At this time, the adjustment part is in a stable state, and the adjustment of the engagement part is also in a stable state.
[0038] In the embodiments of this utility model, please refer to Figure 3 and Figure 4 The adjustment part includes multiple positioning plates 31 arranged in a ring and welded to the outer wall of the circumference of the connecting pipe 2. A groove 32 is provided on one side of the positioning plate 31 along the radial direction of the connecting pipe 2. A first slide 33 penetrating the positioning plate 31 is provided at the bottom of the inner side of the groove 32.
[0039] A concentrically arranged positioning cylinder 34 is rotatably connected to the outside of the connecting pipe 2. An adjusting plate 35 close to the positioning plate 31 is welded and fixed to one end of the positioning cylinder 34. A second slide 36, which is inclined and corresponds to the number and position of the first slide 33, is opened on the side of the adjusting plate 35 facing the positioning plate 31. An arc-shaped plate 37 is also welded and fixed to the outer circumference of the positioning cylinder 34. Multiple annularly distributed bayonets 38 are opened on the outer circumference of the arc-shaped plate 37.
[0040] The engagement part includes a slide 39, which is embedded in and slidably connected to the inside of the slide groove 32. A transmission pin 310 is vertically welded to one side of the slide 39. The transmission pin 310 passes through the first slide 33 and extends into the inside of the second slide 36. A rubber block 311 that can contact the insulating sleeve body 1 is also bonded and fixed to the other side of the slide 39.
[0041] It should be noted that in the locking assembly 3, the positioning cylinder 34 is rotatably mounted on the connecting pipe 2 (a handle can be installed on the positioning cylinder 34 to facilitate the operation of the positioning cylinder 34 when it rotates). Rotating the positioning cylinder 34 can drive the adjusting plate 35 to rotate together. The transmission pin 310 on the slide 39 extends into the inclined second slide 36. Therefore, the rotation of the adjusting plate 35 can exert a force on the transmission pin 310 to drive the entire slide 39 to move along the slide groove 32 until the rubber block 311 at its other end abuts against the insulating sleeve body 1.
[0042] In the embodiments of this utility model, please refer to Figure 3 and Figure 5 The positioning component 4 includes a fixing frame 41, which is welded and fixed to the outer circumference of the connecting pipe 2. A locking rod 42 is rotatably connected to the fixing frame 41, and a torsion spring 43 that abuts against the fixing frame 41 is also fixed on the locking rod 42.
[0043] In normal conditions, the spring force of the torsion spring 43 causes the locking rod 42 to be embedded and fixed inside the locking slot 38.
[0044] It should be noted that after adjusting the engagement part, the locking rod 42 in the positioning member 4 is engaged with the slot 38 on the arc plate 37, thereby limiting the positioning cylinder 34 and thus limiting the slide 39.
[0045] The circuits and controls involved in this utility model are all existing technologies, and will not be described in detail here.
[0046] The above are merely embodiments of this utility model and do not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the description and drawings of this utility model, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
