Description

Technical Field

[0001] The invention relates to the field of transformers, and in particular to a transformer respirator. Background Art

[0002] Transformer respirator is also called transformer desiccant, transformer silica gel can or transformer desiccant. Its function is to filter and absorb moisture and impurities in the air entering the transformer to prevent the transformer from getting damp, so as to ensure the insulation strength of the filter oil in the transformer. When the transformer expands due to heat, it exhales excess air inside the transformer; when the transformer oil temperature drops and contracts, it inhales external air.

[0003] At present, in power equipment, transformer respirators are important accessories for main transformers, capacitor banks, shunt reactors, etc., and their number in the power system is huge. In addition, the moisture-absorbing silicone in the transformer respirator is easily affected by moisture and needs to be replaced frequently. When replacing the silicone in a conventional respirator, it is necessary to use a wrench to remove the four screws connecting the respirator and the connecting pipe, and then remove the fastening screws between the silicone tank and the top cover, before pouring out the damp silicone in the silicone tank and replacing it. This process requires tools such as wrenches and sockets, and when removing the screws, one person needs to tighten the screws while another person fixes the respirator to prevent it from falling, which is a cumbersome process.

[0040] Embodiment 1:

[0041] like Figures 1 to 3 As shown, this embodiment provides a transformer respirator, which is installed on the transformer and is used to filter and absorb moisture and impurities in the air entering the transformer to prevent the transformer from getting damp. The transformer respirator includes a silica gel tank 3, a top cover 1 for sealing the silica gel tank 3, a clamping arm 5 and a first clamping assembly 2. The clamping arm 5 is arranged on opposite sides of the top cover 1, the silica gel tank 3 is arranged in the two clamping arms 5, and the first clamping assembly 2 is arranged on opposite sides of the silica gel tank 3. The silica gel tank 3 is clamped and connected with the top cover 1 through the first clamping assembly 2. Without tools, the silica gel or the silica gel tank 3 can be replaced simply and quickly.

[0042] See also Figure 1 The clamping arm 5 is provided with a guide groove 6, and the first clamping assembly 2 is provided at opposite sides of the silicone tank 3. The first clamping assembly 2 cooperates with the guide groove 6 to drive the silicone tank 3 to move from the first end of the guide groove 6 to the second end of the guide groove 6; when the first clamping assembly 2 is located at the first end of the guide groove 6, the first clamping assembly 2 rotates to clamp the silicone tank 3 to the top cover 1; when the first clamping assembly 2 is located at the second end of the guide groove 6, the first clamping assembly 2 is placed at the second end of the guide groove 6, and the second end of the guide groove 6 can support the first clamping assembly 2. The first clamping assembly 2 drives the silicone tank 3 to rotate to flip the silicone tank 3 to a set angle, and the silicone can be replaced through the open end of the silicone tank 3 without separating the top cover 1 from the silicone tank 3. The guide groove 6 also includes a notch 63, which is provided near the second end. The first clamping assembly 2 can move out of the guide groove 6 from the notch 63 to separate the silicone tank 3 from the top cover 1, and then the silicone tank 3 can be replaced.

[0043] In the transformer respirator in this embodiment, the first clamping assembly 2 includes a connecting rod 22 and a first clamping piece 21. The first clamping piece 21 and the connecting rod 22 are both made of metal materials such as steel and iron. Connecting arms are provided on opposite sides of the silicone tank 3. The connecting arms are parallel to the center line of the silicone tank 3. The first clamping assembly 2 is connected to the silicone tank 3 through the connecting arms. The connecting rod 22 is placed in the guide groove 6. One end of the connecting rod 22 is connected to the connecting arm. The other end of the connecting rod 22 is rotatably connected to the first clamping piece 21 through a pin shaft. The first clamping piece 21 can drive the connecting rod 22 to move in the guide groove 6. When the first clamping piece 21 is at the first end, the first clamping piece 21 can rotate relative to the connecting rod 22 and abut against the clamping arm 5. When the first clamping piece 21 is at the second end, the first clamping piece 21 can drive the silicone tank 3 to rotate a set angle through the connecting rod 22.

[0044] See also Figure 2 In this embodiment, the above-mentioned setting angle is 90°. Of course, in other embodiments, the setting angle can also be 60° or 120°.

[0045] like Figure 3 As shown, the first clamping member 21 includes an abutting portion 211 and a pressing portion 212, the abutting portion 211 is configured as an arc shape, when the first clamping member 21 is located at the first end, the first clamping member 21 rotates, the arc-shaped abutting portion 211 abuts against the clamping arm 5, and the pressing portion 212 is configured as a trapezoidal arm, so that the first clamping member 21 can be driven to rotate with a relatively small force. An avoidance groove is provided on the first clamping member 21, the avoidance groove is located at the abutting portion 211, and the connecting rod 22 is connected to the avoidance groove, so that the first clamping member 21 can rotate around the connecting rod 22.

[0046] Of course, in other embodiments, the pressing portion 212 may also be other structures such as a cylindrical arm.

[0047] The guide groove 6 includes a first guide groove 61 and a second guide groove 62, the first guide groove 61 and the second guide groove 62 are connected, the end of the first guide groove 61 away from the second guide groove 62 is the first end, and the end of the second guide groove 62 away from the first guide groove 61 is the second end. The second guide groove 62 extends from the connecting end of the second guide groove 62 and the first guide groove 61 in a direction away from the top cover 1, and the second guide groove 62 is parallel to the center line of the silicone jar 3, so that when the first clamping assembly 2 moves from the first end to the second end along the guide groove 6, there is a space between the top cover 1 and the silicone jar 3 for rotating the silicone jar 3.

[0048] In the transformer breather of this embodiment, in order to ensure the sealing of the transformer breather, a sealing gasket 4 is arranged between the top cover 1 and the silicone tank 3. The sealing gasket 4 is made of elastic material such as rubber. When the first clamping member 21 is rotated to abut against the clamping arm 5, it can drive the silicone tank 3 to move toward the top cover 1 and press the sealing gasket 4 to ensure the sealing between the top cover 1 and the silicone tank 3.

[0049] The first guide groove 61 and the second guide groove 62 are arranged at an angle, and the distance between the communicating ends of the first guide groove 61 and the second guide groove 62 and the top cover 1 is greater than or equal to the distance between the first end and the top cover 1 .

[0050] In this embodiment, the distance between the connecting end of the first guide groove 61 and the second guide groove 62 and the top cover 1 is greater than the distance between the first end and the top cover 1. When the top cover 1 is clamped with the silicone jar 3, the first clamping assembly 2 drives the silicone jar 3 to move to the first end in the direction close to the top cover 1, applies a pressing force to the sealing gasket 4, and then rotates the first clamping assembly 2 so that the abutting portion 211 abuts against the clamping arm 5, and the silicone jar 3 is clamped to the top cover 1, so that the sealing between the silicone jar 3 and the top cover 1 is better.

[0051] Of course, in other embodiments, the distance between the communicating ends of the first guide groove 61 and the second guide groove 62 and the top cover 1 may also be equal to the distance between the first end and the top cover 1 .

[0052] See also Figure 3 The first clamping member 21 also includes a connecting hole 213. The first clamping member 21 is provided with an avoidance groove, which is located at the abutting portion 211. Both side walls of the avoidance groove are provided with connecting holes 213. The pin is rotatably provided in the connecting hole 213. One end of the connecting rod 22 connected to the first clamping member 21 is provided with a through hole. The connecting rod 22 is located in the avoidance groove. The through hole is arranged opposite to the two connecting holes 213. The pin is inserted from the connecting hole 213 of one side wall of the avoidance groove and is interference fit with the through hole. The other end of the pin is inserted into the connecting hole 213 of the other side wall of the avoidance groove, so that the first clamping member 21 can rotate relative to the connecting rod 22. Of course, a bearing can also be provided in the connecting hole 213, and both ends of the pin are rotatably provided in the connecting hole 213 through the bearing.

[0053] See also Figure 4 and Figure 5 The transformer respirator also includes an oil seal cup 8, which is arranged at the bottom of the silica gel tank 3 and is detachably connected to the silica gel tank 3. The oil seal cup contains filtered oil to isolate the air.

[0054] The opening of the oil seal cup 8 is provided with a flange. By providing the second clamping assembly 7 on the silicone tank 3, the flange of the oil seal cup 8 cooperates with the second clamping assembly 7 to insert the oil seal cup 8 into the silicone tank 3. The second clamping assembly 7 includes a second clamping member 71 and a connecting member 72. The second clamping member 71 is rotatably connected to the silicone tank 3 through the connecting member 72. One end of the second clamping member 71 is provided with a first clamping portion 711, and the other end of the second clamping member 71 is provided with a second clamping portion 712. When installing the oil seal cup 8, the oil seal cup 8 is inserted into the insertion port of the silicone tank 3. During the insertion process, the flange abuts against the second clamping member 71. The second clamping member 71 rotates under the action of the insertion force of the oil seal cup 8, so that the first clamping portion 711 of the second clamping member 71 can be clamped between the flange and the outer wall of the oil seal cup 8. At the same time, the second clamping portion 712 of the second clamping member 71 is clamped with the silicone tank 3 and can protrude from the outer wall of the silicone tank 3. When removing the oil seal cup 8, the second clamping part 712 protruding from the outer wall of the silica gel tank 3 is pressed, and the second clamping part 71 rotates, so that the first clamping part 711 can be disengaged from the oil seal cup 8. In the transformer respirator, the assembly and disassembly of the oil seal cup 8 does not require precise positioning, and the oil seal cup 8 can be quickly installed by simply inserting the oil seal cup 8 into the plug interface. When disassembling, the second clamping part 712 is pressed to disengage the oil seal cup 8, and the oil seal cup 8 can be taken out. The oil seal cup 8 can be replaced simply and quickly, thereby ensuring the cleanliness of the filtered oil in the transformer.

[0055] See also Figure 5 In the transformer respirator of this embodiment, the first clamping portion 711 includes a first abutting surface 7111 and a second abutting surface set at an angle, and the connection between the first abutting surface 7111 and the second abutting surface is set in an arc shape; when installing the oil seal cup 8, the oil seal cup 8 is inserted into the plug-in port of the silicone tank 3. During the insertion process, the cup wall of the oil seal cup 8 can slide along the arc surface of the first clamping portion 711, so that the first clamping portion 711 of the second clamping member 71 is clamped between the flange and the outer wall of the oil seal cup 8.

[0056] The second clamping assembly 7 includes a connecting piece 72, and the second clamping piece 71 is rotatably connected to the silicone can 3 through a pin. When the oil seal cup 8 enters the plug-in interface, the flange abuts against the second abutting surface of the first clamping part 711 and compresses the connecting piece 72. The connecting piece 72 drives the second clamping piece 71 to rotate, so that the first clamping part 711 slides between the flange and the outer wall of the oil seal cup 8. At this time, the first abutting surface 7111 abuts against the lower surface of the flange, and the second abutting surface abuts against the outer wall of the oil seal cup 8. At the same time, the first clamping part 711 is clamped with the silicone can 3.

[0057] In order to install the second clamping assembly 7 at the plug interface, an oblique groove is provided on the inner wall of the plug interface, and the oblique groove gradually slopes downward from the center of the silicone tank 3. The second clamping member 71 includes a connecting surface 713, and the connecting surface 713 and the bottom surface of the oblique groove are both provided with grooves, and a connecting column is provided in the groove, and the two ends of the connecting member 72 are respectively sleeved on the connecting surface 713 and the connecting column on the bottom surface of the oblique groove.

[0058] Of course, in other embodiments, the connecting member 72, the connecting surface 713 and the bottom surface of the inclined groove may also be connected by welding or the like.

[0059] A through hole 32 communicating with the outside is provided at the inclined groove of the silicone jar 3. The second clamping member 71 also includes a connecting hole 7112. The connecting hole 7112 is provided between the connecting member 72 and the first clamping portion 711, and passes through the two side surfaces adjacent to the connecting surface 713. After the pin is inserted into the through hole 32, it is matched and connected with the connecting hole 7112, so that the pin is fixedly connected to the second clamping member 71, and the second clamping member 71 can rotate relative to the silicone jar 3.

[0060] The diameter of the pin matches the diameter of the connecting hole 7112, so as to achieve an interference fit effect.

[0061] In order to facilitate the removal of the oil seal cup 8, the first clamping part 711 can be easily pressed on the outer wall of the silicone tank 3 to drive the first clamping part 711 to rotate. The first clamping part 711 is configured as a protrusion, and the silicone tank 3 is provided with a clamping hole that penetrates the outer wall of the silicone tank 3. The clamping hole is configured as a conical hole. The protrusion can be clamped with the conical hole and protrude from the outer wall of the silicone tank 3.

[0062] In this embodiment, the silicone tank 3 includes a vent pipe 31, which is used to connect the silicone tank 3 and the oil seal cup 8. An insertion interface is formed between the inner wall of the silicone tank 3 and the outer wall of the vent pipe 31. The insertion interface is trumpet-shaped, and the outer diameter of the flange is adapted to the minimum diameter of the trumpet-shaped insertion interface so that the oil seal cup 8 can enter the insertion interface and connect with the silicone tank 3.

[0063] In order to ensure that the oil seal cup 8 can be stably sleeved under the silicone tank 3, the transformer breather includes at least two second clamping assemblies 7, and the second clamping assemblies 7 are spaced apart from the silicone tank 3, thereby further improving the installation stability of the oil seal cup 8.

[0064] In this embodiment, two second clamping components 7 are provided, and the two second clamping components 7 are symmetrically arranged in the circumferential direction of the trumpet-shaped opening.

[0065] Of course, in other embodiments, the second clamping components 7 may also be provided in a plurality of numbers, such as three, four or five, and the plurality of second clamping components 7 are evenly spaced around the circumference of the trumpet-shaped opening.
