Description

Technical Field

[0001] The invention relates to the technical field of power equipment protection, and more specifically, to a transformer low-voltage side protective cover and an installation tool thereof. Background Art

[0002] Transformer is an indispensable key equipment in the power system, which plays an extremely important role in the conversion and distribution of electric energy. The low-voltage side connection of the transformer is usually directly affected by the external environment and is easily affected by physical damage and environmental factors, such as humidity, dust and external force impact, which leads to unstable operation of the transformer and may cause safety hazards. The traditional transformer low-voltage side protective cover is often only suitable for one wiring method and the corresponding angle.

[0030] The present invention is described in detail below in conjunction with the accompanying drawings and embodiments.

[0031] The present invention provides a transformer low voltage side protective cover and an installation tool thereof, such as Figure 1 As shown, it comprises: a first cylinder 1 and a second cylinder 2; the first cylinder 1 is provided with a first slit 11; the second cylinder 2 is provided with a second slit 21; one end of the first cylinder 1 is provided with a connecting portion 12; one end of the second cylinder 2 is rotatably connected to the connecting portion 12; the connecting portion 12 is provided with a limiting baffle 121 for limiting the rotation direction of the second cylinder 2; both sides of the inner wall of the connecting portion 12 are provided with a block 13; both sides of the second cylinder 2 are provided with a block for cooperating with the block 13 to limit the rotation direction of the second cylinder The first card slot 22, the second card slot 23 and the third card slot 24 are used to limit and lock the position of the second cylinder 2; the first card slot 22, the second card slot 23 and the third card slot 24 are arranged in a ring with equal distance; the block 13 can be placed in the corresponding first card slot 22, the second card slot 23 or the third card slot 24; the first disassembly plate 25 and the second disassembly plate 26 are symmetrically arranged on both sides of the second slit 21; the two first disassembly plates 25 are detachably connected to the second cylinder 2; the two second disassembly plates 26 are detachably connected to the second cylinder 2.

[0032] Specifically, the connection portion 12 on the first cylinder 1 is rotatably connected to the second cylinder 2 to realize the rotation between the first cylinder 1 and the second cylinder 2, and the angle adjustment and fixed locking between the first cylinder 1 and the second cylinder 2 are realized through the cooperation between the block 13 and the first slot 22, the second slot 23 and the third slot 24. The flexible angle adjustment can not only meet different installation requirements, but also ensure that the low-voltage side of the transformer is effectively protected; the limit baffle 121 can effectively limit the rotation angle of the second cylinder 2 to prevent it from exceeding the maximum stroke, resulting in a situation where it cannot be used normally; during the rotation of the second cylinder 2, a part of the second cylinder 2 will be placed in the first cylinder 1. In order to effectively avoid the problem of wear and damage between the second cylinder 2 and the equipment components on the low-voltage side of the transformer, the first disassembly plate 25 and the second disassembly plate 26 can be disassembled according to actual usage conditions, thereby leaving enough space for the equipment components on the low-voltage side of the transformer to avoid damage.

[0033] In another embodiment, two hooks are further provided on one end of the first cylinder 1 close to the second cylinder 2, and the two hooks are symmetrically arranged. During the installation process, the second cylinder 2 can be pried apart from the second slit 21, and the baffles on both sides can be pried apart and snapped onto the two hooks. Then, the installation tool 5 is used to pry apart the first cylinder 1 from the first slit 11 on the first cylinder 1, thereby driving the second cylinder 2 to be pried apart synchronously, thereby achieving the effect of quickly installing the protective cover, without the need for additional steps to pry apart the second cylinder 2, resulting in an incomplete closure between the first cylinder 1 and the second cylinder 2, resulting in a gap, resulting in a poor protection effect.

[0034] In another embodiment, a through hole is further provided on the first cylinder 1, allowing the operator to conveniently use a thermometer to manually measure the temperature of the low-voltage side of the transformer. This convenient design reduces the need to disassemble the equipment during the temperature measurement process and improves work efficiency. Through manual temperature measurement, the temperature changes on the low-voltage side of the transformer can be monitored in time. Once the temperature is too high, the operator can immediately take corresponding measures, such as reducing the load or performing equipment maintenance, so as to prevent failures and damage and ensure the safety of equipment operation.

[0035] Optionally, a temperature measuring hole for installing a temperature measuring device is provided on the connecting portion 12; an arc-shaped hole corresponding to the temperature measuring hole is provided on the second cylinder 2; and the arc-shaped hole is connected to the temperature measuring hole.

[0036] Specifically, the temperature measuring hole can conveniently install the temperature measuring device, so that the operator can obtain the data of the working status of the transformer in real time, which is helpful to timely discover potential problems and ensure the safe operation of the equipment; the arc hole set will not collide with the probe part of the temperature measuring device during the rotation of the second cylinder 2, causing damage.

[0037] Furthermore, when the two clamping blocks 13 are both placed in the corresponding first clamping slots 22, the angle between the first cylinder 1 and the second cylinder 2 is 180 degrees, which is suitable for the wiring method in which the low-voltage side of the transformer is a straight-out wiring method.

[0038] Specifically, when the wiring method on the low-voltage side of the transformer is a straight wire outlet, in this method, the angle on the low-voltage side is 180 degrees. By clamping the block 13 of the first cylinder 1 and placing it in the corresponding first slot 22 of the second cylinder 2, the angle between the first cylinder 1 and the second cylinder 2 is made to be 180 degrees. The first cylinder 1 and the second cylinder 2 are pried apart from the first slit 11 and the second slit 21 by the installation tool 5, and the equipment components to be protected on the low-voltage side of the transformer are placed in the first cylinder 1 and the second cylinder 2. Then, the first cylinder 1 and the second cylinder 2 are separated from the installation tool 5, and the closure is completed by the material toughness of the first cylinder 1 and the second cylinder 2 themselves. The installation and setting of the protective cover can be completed without the need for additional installation parts or other connecting parts. It can be quickly locked and released, which improves the efficiency of daily maintenance and overhaul and reduces the complexity of personnel operation.

[0039] Furthermore, when the two clamping blocks 13 are both placed in the corresponding second clamping grooves 23, the angle between the first cylinder 1 and the second cylinder 2 is 135 degrees, which is suitable for the wiring method in which the low-voltage side of the transformer is a wiring copper plate.

[0040] Specifically, when the wiring method of the low-voltage side of the transformer is a wiring copper plate, in this method, the angle of the low-voltage side is 135 degrees. By clamping the block 13 of the first cylinder 1 and placing it in the second clamping groove 23 corresponding to the second cylinder 2, the angle between the first cylinder 1 and the second cylinder 2 is 135 degrees, and the first disassembly plate 25 is removed from the second cylinder 2 to avoid the first disassembly plate 25 being placed in the first cylinder 1 and contacting with the equipment components on the low-voltage side of the transformer during the installation process, thereby leaving enough space; the first cylinder 1 and the second cylinder 2 are pried apart from the first slit 11 and the second slit 21 by the installation tool 5, and the equipment components to be protected on the low-voltage side of the transformer are placed in the first cylinder 1 and the second cylinder 2, and then the first cylinder 1 and the second cylinder 2 are separated from the installation tool 5, and the closure is completed by the material toughness of the first cylinder 1 and the second cylinder 2 themselves. The installation and setting of the protective cover can be completed without the need for additional installation parts or other connecting parts, and can be quickly locked and released, thereby improving the efficiency of daily maintenance and overhaul and reducing the complexity of personnel operation.

[0041] Furthermore, when the two clamping blocks 13 are both placed in the corresponding third clamping slots 24, the angle between the first cylinder 1 and the second cylinder 2 is 90 degrees to be suitable for the wiring method in which the low-voltage side of the transformer is a wiring ear.

[0042] Specifically, when the wiring method of the low-voltage side of the transformer is a wiring ear, in this method, the angle of the low-voltage side is 90 degrees. By clamping the block 13 of the first cylinder 1 and placing it in the second clamping groove 23 corresponding to the second cylinder 2, the angle between the first cylinder 1 and the second cylinder 2 is 135 degrees, and the first disassembly plate 25 and the second disassembly plate 26 are removed from the second cylinder 2 to avoid the first disassembly plate 25 being placed in the first cylinder 1 and contacting with the equipment components on the low-voltage side of the transformer during the installation process, thereby leaving enough space; the first cylinder 1 and the second cylinder 2 are separated from the first slit 11 and the second slit 21 by the installation tool 5, and the equipment components to be protected on the low-voltage side of the transformer are placed in the first cylinder 1 and the second cylinder 2, and then the first cylinder 1 and the second cylinder 2 are separated from the installation tool 5, and the closure is completed by the material toughness of the first cylinder 1 and the second cylinder 2 themselves. The installation and setting of the protective cover can be completed without the need for additional installation of mounting parts or other connecting parts, and can be quickly locked and released, thereby improving the efficiency of daily maintenance and overhaul and reducing the complexity of personnel operation.

[0043] Furthermore, a first limiting cover 3 is disposed on the other end of the first cylinder 1 ; the first limiting cover 3 is detachably connected to the first cylinder 1 ; and a third slit 31 corresponding to the first slit 11 is formed on the first limiting cover 3 .

[0044] Specifically, the first limiting cover 3 is made of silicone, which is used to reduce the wear on the equipment components on the low-voltage side of the transformer, and further extend the service life of the equipment components on the low-voltage side of the transformer; the outer diameter of the first limiting cover 3 gradually decreases from the inside to the outside, so as to prevent the overall limiting protective cover from being disengaged and displaced due to environmental factors such as vibration, resulting in poor protection effect.

[0045] Furthermore, a second limiting cover 4 is disposed on the other end of the second cylinder 2 ; the second limiting cover 4 is detachably connected to the second cylinder 2 ; and a fourth slit 41 corresponding to the second slit 21 is formed on the second limiting cover 4 .

[0046] Specifically, the second limiting cover 4 is made of silicone, which is used to reduce the wear on the equipment components on the low-voltage side of the transformer, and further extend the service life of the equipment components on the low-voltage side of the transformer; the outer diameter of the second limiting cover 4 gradually decreases from the inside to the outside, so as to prevent the overall limiting protective cover from being disengaged and displaced due to environmental factors such as vibration, resulting in poor protection effect.

[0047] A protective cover installation tool 5 includes: an insulating operating rod 6, a movable clamp 8 and an adjustment component 7 for adjusting the angle of the movable clamp 8; the adjustment component 7 is detachably connected to the insulating operating rod 6; and the movable clamp 8 is fixedly connected to the adjustment component 7.

[0048] In the best embodiment, the movable clamp 8 is adjusted to an angle suitable for installation through the adjustment component 7, and the protective cover is fixed as a whole through the movable clamp 8 so that it is in a state to be installed. The operator installs the protective cover on the low-voltage side of the transformer through the insulating operating rod 6. The use of the insulating operating rod 6 can effectively protect the safety of the operator. After the protective cover is installed, the movable clamp 8 and the protective cover are separated to complete the steps of installing the protective cover. It is convenient and quick, and there is no need to install the fixings after the installation is completed. The scene adaptability is stronger.

[0049] Furthermore, the adjustment assembly 7 includes: a mounting seat 71, an adjusting screw and an adjusting bolt for limiting the adjusting screw; the mounting seat 71 is detachably connected to the insulating operating rod 6; one end of the adjusting screw is fixedly connected to the movable clamp 8, and the other end is rotatably connected to the mounting seat 71; the adjusting bolt is rotatably connected to the mounting seat 71 and can abut against the adjusting screw.

[0050] Furthermore, a first clamping hand 81 and a second clamping hand 82 are provided at one end of the movable clamp 8; the first clamping hand 81 and the second clamping hand 82 are both fixedly connected to the movable clamp 8; a third clamping hand 83 and a fourth clamping hand 84 are provided at the other end of the movable clamp 8; the third clamping hand 83 and the fourth clamping hand 84 are both fixedly connected to the movable clamp 8; the first clamping hand 81 and the third clamping hand 83 are symmetrically arranged; the second clamping hand 82 and the fourth clamping hand 84 are symmetrically arranged.

[0051] Specifically, the first clamp 81 and the third clamp 83 cooperate to pry the first cylinder 1 apart from the first slit 11, so as to facilitate the placement of the equipment components on the low-voltage side of the transformer in the first cylinder 1; the second clamp 82 and the fourth clamp 84 cooperate to pry the second cylinder 2 apart from the second slit 21, so as to facilitate the placement of the equipment components on the low-voltage side of the transformer in the second cylinder 2; the length of the second clamp 82 and the fourth clamp 84 is greater than that of the first clamp 81 and the third clamp 83, so as to adapt to the situation that when the protective cover is adjusted to suit the 90-degree wiring method and the first removal plate 25 and the second removal plate 26 are removed, the second clamp 82 and the fourth clamp 84 cannot pry apart the second cylinder 2.

[0052] In other embodiments, a driving assembly is added to the movable clamp 8 to enable the first clamp 81 and the third clamp 83 to quickly separate and retract, and to enable the second clamp 82 and the fourth clamp 84 to quickly separate and retract, so that the entire installation and setting process is more convenient and quick.

[0053] In the first embodiment, in the wiring mode with an angle of 180 degrees on the low-voltage side of the transformer, that is, the wire is connected directly, the clamp block 13 is clamped into the corresponding first clamping groove 22, so that the angle between the first cylinder 1 and the second cylinder 2 is 180 degrees at this time, so as to adapt to the shape angle of the equipment components on the wiring side of the transformer at this time, and the first cylinder 1 and the second cylinder 2 are separated by the movable clamp 8 on the installation tool 5 to be installed, and the first clamp 81 and the third clamp 83 are inserted through the first slit 11 on the first cylinder 1, and then the first cylinder 1 is separated to facilitate the placement of the equipment components on the low-voltage side of the transformer in the first cylinder 1, and then the first cylinder 1 is separated.

After the installation is completed, the second clamp 82 and the fourth clamp 84 are separated from the second cylinder 2, and the second cylinder 2 material toughness automatically closes the cover and is set on the equipment element on the low-voltage side of the transformer to achieve the protection function;

[0054] In the second embodiment, in the wiring method of the low-voltage side of the transformer with an angle of 135, that is, the wiring copper plate, the card block 13 is connected to the corresponding second card slot 23, and the first removal plate 25 on the second cylinder 2 is removed to leave enough space to accommodate the equipment components on the low-voltage side of the transformer, so that the angle between the first cylinder 1 and the second cylinder 2 is 135 degrees at this time to adapt to the shape angle of the equipment components on the wiring side of the transformer at this time, and the first cylinder 1 and the second cylinder 2 are separated by the movable clamp 8 on the installation tool 5 to be installed, and the first clamp 81 and the third clamp 83 are inserted through the first slit 11 on the first cylinder 1, and then the first cylinder 1 is separated to facilitate the installation of the transformer.

After the installation is completed, the second clamp 82 and the fourth clamp 84 are separated from the second cylinder 2, and the automatic closing cover is set on the equipment components on the low-voltage side of the transformer through the material toughness of the second cylinder 2, so as to achieve the protection function;

[0055] In the third embodiment, in the wiring method of the low-voltage side of the transformer with a 90-degree angle, that is, the wiring ear, the card block 13 is carded into the corresponding third card slot 24, and the first removal plate 25 and the second removal plate 26 on the second cylinder 2 are removed to leave enough space to accommodate the equipment components on the low-voltage side of the transformer, so that the angle between the first cylinder 1 and the second cylinder 2 is 90 degrees at this time to adapt to the shape and angle of the equipment components on the wiring side of the transformer at this time, and the first cylinder 1 and the second cylinder 2 are separated by the movable clamp 8 on the installation tool 5 to be installed, and the first clamp 81 and the third clamp 83 are inserted through the first slit 11 on the first cylinder 1, and then the first cylinder 1 is separated to facilitate installation.
