Technical Field

[0001] The utility model relates to the field of insulating cylinders, in particular to an improved winding insulating cylinder. Background Art

[0002] For medium and high voltage transformers or reactors, in order to reduce the space distance between the coil and the core, between the inner coil and the outer coil, and to enhance the insulation electrical strength, an insulating cylinder is generally installed between the coil and the core, between the inner coil and the outer coil. The height of the insulating cylinder currently used is generally fixed, and the insulating cylinder is fixed on the base in an integrated manner, and it is impossible to replace and install different types of insulating cylinders on the base.

[0003] According to the disclosed patent 201821911095.2, the composite insulating tube includes a composite insulating tube body, the tube wall of the composite insulating tube body includes silicone rubber, epoxy resin and rubber-coated vacuum tube from the outside to the inside, the inner wall of the rubber-coated vacuum tube is provided with a first thread, a mounting seat is provided under the composite insulating tube body, a first screw hole is provided in the mounting seat, a full-thread bolt is connected to the inner thread of the mounting seat, the full-thread bolt includes an elastic tube, a second thread is provided on the outer wall of the elastic tube, a deformation tube is inserted in the elastic tube, the deformation tube is composed of four segmented tubes, adjacent segmented tubes are connected by a telescopic tube, the telescopic tube includes a fixed tube, a movable tube is connected in the fixed tube, and the movable tube is fixed to the fixed tube by screws. The utility model solves the problem that the height of the insulating cylinder currently used is generally fixed, and the insulating cylinder is fixed on the base in an integrated manner, and different types of insulating cylinders cannot be replaced and installed on the base. In the process of realizing the utility model, the inventor found that at least the following problems in the prior art have not been solved. Although a mounting seat is provided between the composite insulating cylinder body and the base, and a full-threaded bolt with a variable aperture size is installed on the mounting seat to adapt to different types of composite insulating cylinder bodies, an insulating layer is provided on the full-threaded bolt, and the height of the composite insulating cylinder body is changed by the depth of the full-threaded bolt screwed into the composite insulating cylinder body, during use, the traditional winding insulating cylinder is installed with a full-threaded bolt with a variable aperture size. When disassembling and assembling the insulating cylinder, the staff still needs to disassemble and assemble multiple threaded bolts, resulting in low efficiency in disassembling and replacing the insulating cylinder. Moreover, in the process of limiting and fixing the insulating cylinder, the staff generally checks on a fixed date. When the insulating cylinder is loose and displaced, the staff cannot take the initiative to know the situation of the insulating cylinder in time, but only passively perform maintenance. For this reason, it is necessary to design a new technical solution to solve it. Utility Model Content

[0004] The purpose of the utility model is to overcome the deficiencies of the prior art, meet actual needs, and provide an improved winding insulation cylinder to solve the problem that the current traditional winding insulation cylinder is equipped with a full-threaded bolt with a variable aperture size. When disassembling and assembling the insulation cylinder, the staff still needs to disassemble and assemble multiple threaded bolts, resulting in low efficiency in disassembling and replacing the insulation cylinder. Moreover, in the process of limiting and fixing the insulation cylinder, the staff generally conducts inspections on fixed dates. When the insulation cylinder becomes loose and displaced, the staff cannot take the initiative to promptly learn about the condition of the insulation cylinder and can only passively perform maintenance.

[0005] In order to achieve the purpose of the utility model, the technical solution adopted by the utility model is: a winding insulation cylinder with improved design, including an insulation cylinder body, and also including:

[0006] A base, arranged on the top of the insulating cylinder;

[0007] A quick-change mechanism is installed on both sides of the base, and the quick-change mechanism includes two fixed cylinders, which are respectively installed on both sides of the base. A spring is arranged inside the fixed cylinder, and a movable plate is fixed on one side of the spring;

[0008] A moving rod passes through the interior of the fixed cylinder, and the moving rod passes through the spring and the moving plate, and the position where the moving rod and the moving plate pass through is fixedly connected.

[0009] Preferably, the bottom of the insulating cylinder extends into the base, and arc grooves are provided on both sides of one end of the insulating cylinder located in the base.

[0010] Preferably, an arc-shaped clamping plate is clamped inside the arc-shaped groove, a moving rod is fixed to one side of the arc-shaped clamping plate, and a pull rod is fixed to the other end of the moving rod passing through the base.

[0011] Preferably, a groove is provided on the other side of the arc-shaped clamping plate, and a wireless pressure sensor is installed inside the groove.

[0012] Preferably, a plurality of silicone rubbers are installed on the outside of the insulating cylinder, and both sides of the plurality of silicone rubbers penetrate the limiting cylinder, the outer wall of the limiting cylinder is provided with a plurality of openings, and a DFC anti-condensation cotton plate is installed inside the limiting cylinder.

[0013] Preferably, a cylinder top cover is installed on the top of the insulating cylinder.

[0014] Compared with the prior art, the beneficial effects of the present invention are:

[0015] 1. The utility model combines a fixing cylinder, an arc-shaped clamping plate and a spring, so that when the insulating cylinder is inserted into the base, the elastic force of the spring will drive the arc-shaped clamping plate to be clamped into the insulating cylinder, thereby directly limiting and fixing the insulating cylinder. When the insulating cylinder needs to be removed and replaced, it is only necessary to pull the pull rod to disengage the arc-shaped clamping plate from the arc groove, and the insulating cylinder can be directly taken out, thereby realizing convenient and fast disassembly and assembly of the insulating cylinder, eliminating the need to set up multiple threaded bolts, and solving the problem that the traditional wound insulating cylinder is equipped with a full-threaded bolt with a variable aperture size. When disassembling and assembling the insulating cylinder, the staff still needs to disassemble and assemble multiple threaded bolts, resulting in a technical problem of low efficiency in disassembling and assembling the insulating cylinder.

[0016] 2. The utility model can set the wireless pressure sensor on the surface of the arc-shaped pallet through the combination of the arc-shaped pallet, the groove and the wireless pressure sensor. When the arc-shaped pallet is stuck in the arc-shaped groove, the pressure can be sensed by the pressure sensor. When the insulating cylinder is displaced and falls off, the wireless pressure sensor cannot sense the pressure. The wireless pressure sensor will send a signal to the terminal, thereby actively notifying the staff in time, solving the technical problem that in the process of limiting and fixing the insulating cylinder, the staff usually checks on a fixed date. When the insulating cylinder is loosened and displaced, the staff cannot actively and promptly know the condition of the insulating cylinder and can only passively perform maintenance.

[0021] The utility model is further described below in conjunction with the accompanying drawings and embodiments:

[0022] Example 1: Improved winding insulation tube, see Figures 1 to 3, including an insulating cylinder 101, and also including: a base 1, which is arranged on the top of the insulating cylinder 101; a quick replacement mechanism, which is installed on both sides of the base 1, and the quick replacement mechanism includes two fixed cylinders 205, which are respectively installed on both sides of the base 1, and a spring 206 is arranged inside the fixed cylinder 205, and a movable plate 207 is fixed on one side of the spring 206; a movable rod 2 is passed through the fixed cylinder 205, and the movable rod 2 passes through the spring 206 and the movable plate 207, and the position where the movable rod 2 and the movable plate 207 pass through is fixedly connected. First, the insulating cylinder 101 is inserted into the base 1, and the arc groove 203 on the surface of the insulating cylinder 101 is facing the position of the arc clamping plate 204. Since the spring 206 is arranged inside the fixed cylinder 205, the elastic force of the spring 206 will drive the movable plate 207 and the movable rod 2 to move. When the insulating cylinder 101 is disassembled and replaced, the pull rod 202 can be pulled by hand, and the pull rod 202 can drive the moving rod 2 to move, and the moving rod 2 can drive the moving plate 207 to squeeze the spring 206, so that the arc clamping plate 204 is disengaged from the arc groove 203, and the insulating cylinder 101 can be directly taken out, realizing convenient and fast disassembly and assembly of the insulating cylinder 101, eliminating the need to set up multiple threaded bolts, and solving the problem that the traditional winding insulating cylinder is equipped with full-threaded bolts with variable aperture size. When disassembling and assembling the insulating cylinder, the staff still needs to disassemble and assemble multiple threaded bolts, resulting in a technical problem of low efficiency in disassembling and assembling the insulating cylinder.

[0023] For details, see Figure 2 The bottom of the insulating cylinder 101 extends into the base 1 , and arc grooves 203 are provided on both sides of one end of the insulating cylinder 101 located in the base 1 .

[0024] For further information, see Figure 2 An arc-shaped clamping plate 204 is clamped inside the arc-shaped groove 203 , a moving rod 2 is fixed to one side of the arc-shaped clamping plate 204 , and the other end of the moving rod 2 passes through the base 1 and is fixed to a pull rod 202 .

[0025] It is worth noting that see Figure 2A groove 201 is provided on the other side of the arc-shaped card plate 204, and a wireless pressure sensor 208 is installed inside the groove 201. The wireless pressure sensor 208 is set on the surface of the arc-shaped card plate 204, and the wireless pressure sensor 208 is connected to the terminal host. When the arc-shaped card plate 204 clamps the arc-shaped groove 203, the pressure can be sensed through the pressure sensor. When the insulating cylinder is displaced and falls off, the wireless pressure sensor 208 cannot sense the pressure. The wireless pressure sensor 208 will send a signal to the terminal, thereby actively notifying the staff in time, solving the technical problem that in the process of limiting and fixing the insulating cylinder, the staff generally checks on a fixed date. When the insulating cylinder is loose and displaced, the staff cannot actively and timely know the condition of the insulating cylinder, but can only passively perform maintenance.

[0026] It is worth noting that see Figure 1 and Figure 3 A plurality of silicone rubbers 103 are installed on the outside of the insulating cylinder 101, and both sides of the interior of the plurality of silicone rubbers 103 penetrate the limiting cylinder 3. The outer wall of the limiting cylinder 3 is provided with a plurality of openings 301, and a DFC anti-condensation cotton board 302 is installed inside the limiting cylinder 3. The setting of the limiting cylinder 3 can not only limit multiple positions of the insulating cylinder 101, thereby improving the stability of the insulating cylinder 101, but also a DFC anti-condensation cotton board 302 is arranged inside the limiting cylinder 3. The DFC anti-condensation cotton board 302 is composed of a cotton-like material substrate grafted with a high-efficiency hydrophilic polymer chain segment, can sense the air humidity in the equipment, and automatically absorb humid gas. When saturated water absorption is reached, the water can be automatically discharged along the opening 301, thereby preventing the insulating cylinder 101 from getting damp.

[0027] It is worth mentioning that see Figure 1 A cylinder top cover 102 is installed on the top of the insulating cylinder 101.

[0028] When using the improved winding insulation cylinder, first insert the insulation cylinder 101 into the base 1, and align the arc groove 203 on the surface of the insulation cylinder 101 with the position of the arc clamping plate 204. Since a spring 206 is arranged inside the fixed cylinder 205, the elastic force of the spring 206 will drive the movable plate 207 and the movable rod 2 to move, and the movable rod 2 will drive the arc clamping plate 204 to move, so that the arc clamping plate 204 is stuck in the arc groove 203 on the surface of the insulation cylinder 101, so as to directly limit and fix the insulation cylinder 101. When it is necessary to disassemble and replace the insulation cylinder 101, the pull rod 202 can be pulled by hand, and the pull rod 202 will drive the movable rod 2 to move, and the movable rod 2 will drive the movable plate 207 to squeeze the spring 206, so that the arc clamping plate 204 is separated from the arc groove 203, and the insulation cylinder 101 can be directly taken out, so that the insulation cylinder 101 is replaced. 1 is convenient and quick to disassemble and assemble, eliminating the need to set up multiple threaded bolts. When the arc-shaped clamping plate 204 clamps the arc-shaped groove 203, the pressure can be sensed by the pressure sensor. When the insulating cylinder is displaced and falls off, the wireless pressure sensor 208 cannot sense the pressure. The wireless pressure sensor 208 will send a signal to the terminal, thereby actively notifying the staff in time. The set limit cylinder 3 can not only limit multiple positions of the insulating cylinder 101, thereby improving the stability of the insulating cylinder 101, but also a DFC anti-condensation cotton board 302 is arranged inside the limit cylinder 3. The DFC anti-condensation cotton board 302 is composed of a cotton-like material base material grafted with a high-efficiency hydrophilic polymer chain segment, can sense the air humidity in the equipment, and automatically absorb humid gas. When saturated water absorption is reached, the water can be automatically discharged along the opening 301, thereby preventing the insulating cylinder 101 from getting damp.
