Description

Technical Field

[0001] The utility model relates to the technical field of temperature controller plug seats, and more specifically, to a detachable temperature controller plug seat for a new energy transformer. Background Art

[0002] A transformer is a device that uses the principle of electromagnetic induction to change AC voltage. Its components include but are not limited to a primary coil, a secondary coil, an iron core and an oil tank. The temperature controller on the transformer is installed on the oil tank to monitor the internal oil temperature. The current market and users have requirements for the outer limit dimensions of new energy transformers, requiring that the outer limit dimensions of the transformer be smaller than the size required by the user. Since the oil tank needs to be connected to a thermostat to monitor the temperature, the internal space of the transformer is continuously compressed, and the tail of the temperature-sensing plug rod on the tank wall that enters the oil tank is directly inserted vertically, which may cause the body of the device to be unable to enter the interior of the oil tank normally (interference during the movement), affecting the reduction of the outer limit dimensions.

[0003] The patent with application number 202320662267.1 discloses a compact box-type transformer, including a transformer core, a cage switch, a temperature controller, a pressure relief valve, a high-voltage bushing, a handhole cover, a low-voltage bushing, an oil level gauge, a shell and transformer oil. The public document designs a compact transformer. According to the specification, the installation position and installation effect of the temperature controller in the application have not changed compared with the prior art. However, combined with the requirement that the transformer needs to be "compact", the compression of the internal space of the transformer will affect the installation of the temperature controller, especially the plug seat of the temperature controller on the existing transformer cannot be removed, and the plug rod of the temperature controller cannot change the installation direction, resulting in the failure of the installation of the temperature controller.

[0004] In view of the above problems, we propose a detachable temperature controller plug for a new energy transformer. Utility Model Content

[0005] The utility model provides a detachable temperature controller plug seat for a new energy transformer in order to overcome the problem that a temperature sensing plug rod plug seat on the box wall of the current new energy transformer will cause a part of the transformer body to be unable to normally enter the oil tank.

[0006] In order to solve the above technical problems, the technical solution of the utility model is as follows:

[0007] A detachable temperature controller plug seat for a new energy transformer comprises a fixing portion fixed on a transformer box and a disassembly portion assembled with the fixing portion, wherein a first through hole and a second through hole are respectively provided in the middle of the fixing portion and the disassembly portion, and a temperature sensing plug rod enters the interior of the box through the first through hole and the second through hole in sequence, one side of the fixing portion is beveled, and the beveled surface of the fixing portion is fixedly attached to the transformer box, and the axis of the first through hole is inclined upward compared to the vertical line of the transformer box installation surface after the fixing portion is installed, a first internal thread is provided on the inner wall of the first through hole, and an external thread matching the first internal thread is provided on the bottom of the disassembly portion; a second internal thread is also provided above the inner wall of the second through hole.

[0008] Furthermore, the chamfered surface of the fixing portion is fixed to the mounting surface of the transformer box by welding or gluing.

[0009] Furthermore, a sealing groove coaxial with the first through hole is provided on one end surface of the fixing portion facing the disassembling portion.

[0010] Furthermore, the upper and lower openings of the inner wall of the sealing groove are chamfered.

[0011] Furthermore, a quadrangular head is provided in the middle section of the disassembly portion.

[0012] Furthermore, the plug seat also includes a plug tube, one end of which is interference-connected to the bottom of the second through hole, and the temperature-sensing plug rod enters into the plug tube through the second through hole.

[0013] Furthermore, one end of the plug tube is open, and the other end opening is sealed by circular plate welding, and the sealed end of the plug tube is inserted into the transformer box.

[0014] Furthermore, the fixing part, the plug tube and the circular plate are all made of Q235 steel.

[0015] Compared with the prior art, the beneficial effects of the technical solution of the utility model are:

[0016] The utility model provides a detachable temperature controller plug seat for a new energy transformer, which solves the following problems:

[0017] 1) The box of the traditional new energy transformer is limited by size. When the temperature-sensing plug rod is inserted into the plug seat, the front-to-back distance inside the box may be limited, resulting in the temperature-sensing plug rod not being able to fully enter the oil tank. By beveling one end of the fixing part, the first through hole in the fixing part opens obliquely upward. Therefore, when the temperature-sensing plug rod enters the oil tank, the horizontal stroke can be shortened to ensure smooth entry of the temperature-sensing plug rod.

[0018] 2) The disassembly part is screwed into the first internal thread of the fixed part through the external thread at the bottom. By means of thread disassembly, it is convenient to replace different types of disassembly parts for different thermostats, thereby reducing the difficulty of installing the thermostat;

[0019] 3) A sealing groove is designed on the mounting surface of the fixed part facing the disassembly part. The sealing groove is used to install an O-ring or fill it with sealant. The upper and lower openings of the sealing groove are chamfered to prevent the sharp edge from cutting your hands and to allow the O-ring or the sealant to fill the sealing groove through the upper and lower squeezing of the fixed part and the disassembly part;

[0020] 4) Design a detachable plug tube. The inner diameter of the plug tube must fit the size of the temperature controller plug rod to be installed. The function of the tube is to protect the temperature-sensing plug rod when it enters, to avoid damage caused by contact with the inner wall of the tank due to the size limitation of the oil tank. Another design of the plug tube adopts a bottom sealing method, and the plug tube adopts a seamless steel pipe with high thermal conductivity. BRIEF DESCRIPTION OF THE DRAWINGS

[0042] Furthermore, one end of the plug tube 3 is open, and the other end opening is sealed by welding through a circular plate 31, and the sealed end of the plug tube 3 is inserted into the transformer box.

[0043] Furthermore, the fixing portion 1 , the plug tube 3 and the circular plate 31 are all made of Q235 steel.

[0044] On the basis of Example 1, Example 2 adds a plug tube 3. The function of the plug tube is to protect the temperature-sensing plug rod when it enters, so as to avoid damage caused by the temperature-sensing plug rod contacting the inner wall of the box when entering due to the size limitation of the oil tank; a design of the plug tube 3 adopts a bottom sealing method, and the plug tube adopts seamless steel with high thermal conductivity to avoid liquid leakage and damage to the sensing element in the temperature-sensing plug rod, thereby improving the service life of the temperature controller.
