Description

Technical Field

[0001] The present invention belongs to the technical field of transformers and relates to an energy storage system transformer, in particular to a winding temperature detection device for a transformer. Background Art

[0002] A transformer is a device that uses the principle of electromagnetic induction to change AC voltage. Its main components are the primary coil, the secondary coil and the iron core.

[0003] An energy storage transformer is a device that converts electrical energy into magnetic energy, stores it, and then converts the magnetic energy back into electrical energy when needed. Its operating principle is to utilize the transformer principle, converting electrical energy into magnetic energy through an energy storage inductor for storage, and then converting the magnetic energy back into electrical energy for output when needed through a transformer. Energy storage transformers can manage and optimize electrical energy, achieving energy conservation goals, improving the reliability and stability of power system supply, and ensuring power supply quality.

[0004] A search revealed a Chinese patent document describing a temperature measurement device for transformer windings [Application Number: CN202020249555.0; Publication Number: CN211626687U]. This device accurately measures the temperature of the transformer windings using an infrared temperature detector. The outer casing provides waterproof protection for the internal structure, enabling the device to operate in outdoor environments for extended periods.

[0005] Although the temperature measuring device disclosed in this patent can accurately measure the temperature of the transformer windings through an infrared temperature detector, since multiple windings are arranged inside the energy storage system transformer, the infrared temperature detector outside the transformer cannot achieve accurate temperature measurement of each winding. The installation of an infrared temperature detector outside each winding greatly increases the detection cost. In addition, the installation of multiple sets of detection devices is prone to affect the winding temperature due to heat generated by long-term operation, which increases the hidden dangers of the winding coils in the transformer and affects the safety of the transformer.

By arranging a spring between the winding drum 7 and the movable rod 8, the winding drum 7 has a certain elasticity, which can realize the self-recovery winding of the transmission line 3, and facilitate the transmission line 3 to be accurately extended by stretching. The transmission line 3 is set through one side of the body 1, and the other end of the transmission line 3 is connected to a temperature measuring rod 4 through a connecting assembly 6. Considering the temperature measurement of multiple groups of windings inside the transformer, the temperature measuring rod 4 is telescopically arranged inside the mounting frame assembly 5, and the mounting frame assembly 5 is installed on the upper end of the multiple groups of transformer windings;

[0049] like Figures 1-10 As shown, in order to realize the temperature measurement of multiple groups of windings, the mounting frame assembly 5 includes a top frame 501, and a through-tube 502 is opened inside the top frame 501, and three winding plugs 503 are connected below the through-tube 502. The through-tube 502 and the winding plugs 503 are arranged in a "T" shape, and the three winding plugs 503 are arranged in parallel. By connecting the winding plugs 503 inside the transformer winding and connecting the through-tube 502 above the three winding plugs 503, the user can detect the temperature of different windings by measuring the temperature at the ends of different winding plugs 503, thereby ensuring the accuracy of temperature measurement. In addition, considering the temperature measuring rod 4 In order to ensure the movement accuracy inside the through-tube 502, a mounting plate 601 is telescopically provided on the inner wall of the through-tube 502, and the temperature measuring rod 4 is fixedly installed on the surface of the mounting plate 601. At the same time, limiting grooves 504 are provided on the inner walls of both sides of the through-tube 502, and the inner walls of the limiting grooves 504 are slidably connected with guide blocks 603, and the guide blocks 603 are fixedly installed on both sides of the mounting plate 601. Under the action of the guide blocks 603 provided on the outer wall of the mounting plate 601, the mounting plate 601 can drive the temperature measuring rod 4 on the surface to move accurately and guide inside the through-tube 502, so that the temperature measuring rod 4 can stably measure the temperature above the corresponding winding insert 503.

[0050] like Figures 1-10 As shown, considering the movement accuracy and driving effect of the temperature measuring rod 4, the connecting assembly 6 includes a mounting plate 601, and the mounting plate 601 is fixedly connected to one end of the transmission line 3, and the side of the mounting plate 601 away from the temperature measuring rod 4 is fixedly connected to a protective tube 602, and the protective tube 602 is sleeved and installed on the outer wall of the transmission line 3, so that the protective tube 602 protects the connection between the transmission line 3 and the temperature measuring rod 4, which is beneficial to improve the stability of the transmission line 3 when moving inside the through-tube 502, and further improves the service life of the transmission line 3. At the same time, a plurality of driving limit units are equidistantly arranged in a ring on the outer side of the transmission line 3. Specifically, the driving limit unit includes two fixed seats 604, and the fixed seat 604 is fixedly mounted on the surface of the mounting plate 601. The interior of the fixed seat 604 is rotatably connected to a rotating rod 605, and the outer wall of the rotating rod 605 is fixedly connected to a toothed disc 606, and the toothed disc 606 is arranged between the two fixed seats 604, and both side ends of the rotating rod 605 are A moving wheel 607 is fixedly connected, and the moving wheel 607 is arranged on the outside of the fixed seat 604, and the outer wall of the moving wheel 607 is closely connected to the inner wall of the through-tube 502, and the outer wall of the toothed disc 606 is meshed with a toothed belt 608. Through the meshing connection between the toothed belt 608 and the toothed disc 606, the retraction and unwinding of the toothed belt 608 can realize the rotation of the toothed disc 606, so that the moving wheel 607 drives the connecting assembly 6 to move telescopically inside the through-tube 502, which is convenient for the temperature measuring rod 4 To accurately measure the temperature of the winding tubes 503 at different positions, four sets of toothed belts 608 are arranged in a ring around the circumference of the transmission line 3. The four sets of toothed belts 608 are all made of steel belt material. By providing teeth and grooves on the surface of the steel belt, the toothed belt 608 can realize the transmission of the toothed disc 606 when stretched, which is convenient for driving the moving wheel 607 to rotate. In addition, the steel belt setting of the toothed belt 608 allows the toothed belt 608 to be well stored by being wound, ensuring the working space of the device.

[0051] Both ends of the toothed belt 608 are connected with a winding unit, and the two winding units are respectively installed on the surface of the machine body 1 and the mounting plate 601. Specifically, a through hole for accommodating the transmission line 3 to extend through is opened on one side of the machine body 1, and a winding unit is provided on the outer peripheral side of the through hole. The winding unit is fixedly installed on the outer wall of the machine body 1 through the side plate 6010, and the winding unit is wound and connected with the end of the toothed belt 608 away from the mounting plate 601. By installing the winding unit on the outer wall of the machine body 1, the winding unit can stably assist in winding the transmission line 3 at the outlet part of the machine body 1. At the same time, a winding unit is fixedly connected to the surface of the mounting plate 601, and the winding unit is fixedly installed on the surface of the mounting plate 601 through the side plate 6010, and the winding unit is wound and connected with the end of the toothed belt 608 away from the machine body 1, thereby realizing the precise driving of the winding units on both sides at both ends of the toothed belt 608, which is convenient for precise operation of the toothed belt 608 on both sides. Accurate winding and unwinding, wherein the winding unit includes a side plate 6010, and the interior of the side plate 6010 is connected to a winding rod 609 through a rotating shaft, the outer wall of the winding rod 609 is wound with a toothed belt 608, and the winding rod 609 is driven by a driving component. Specifically, the driving component is an electric motor 6011, and the electric motor 6011 is fixedly installed on the outer side of the side plate 6010, and the output end of the electric motor 6011 is fixedly connected to the winding rod 609, so that the independently set electric motor 6011 drives the independent winding rod 609 to drive, ensuring the rotation effect of the winding rod 609. Through such a setting, under the meshing connection between the toothed belt 608 and the toothed disc 606, the winding and unwinding of the toothed belt 608 can realize the rotation of the toothed disc 606, so that the moving wheel 607 drives the connecting component 6 to move telescopically inside the through tube 502, so that the temperature measuring rod 4 can accurately measure the temperature of the winding tubes 503 at different positions.

[0052] The working principle of the present invention is as follows: when in use, the mounting frame assembly 5 is installed above the transformer, and the winding insert 503 below the through-tube 502 is plugged into the internal temperature measuring point of each winding group, ensuring the connection effect between the winding insert 503 and the through-tube 502, and the temperature measuring rod 4 is arranged inside the through-tube 502 through the connecting assembly 6, and the body 1 is installed outside the transformer. During detection, the winding unit on one side of the connecting assembly 6 is driven, so that the winding rod 609 drives the toothed belt 608 to unwind, and under the meshing action of the toothed belt 608 and the toothed disc 606, the toothed disc 606 drives the moving wheel 607 to rotate, so that the moving wheel 607 drives the mounting plate 601 to move inside the through-tube 502, and by fixing the guide block 603 on the outer wall of the mounting plate 601, it is ensured that the mounting plate 601 drives the temperature measuring rod 4 to move accurately inside the through-tube 502, so that The temperature measuring rod 4 measures the temperature of the winding in the corresponding winding tube 503. By the user driving and moving the temperature measuring rod 4, a single temperature measuring rod 4 can detect the temperature of different windings at different positions inside the through tube 502, and display the temperature through the digital display screen on the surface of the body 1, and the temperature alarm can be issued through the indicator light 2 below. At the same time, by installing a winding unit on the outer wall of the body 1, under the action of the fixed winding position of the toothed belt 608 on one side of the connecting component 6, the winding unit on one side of the body 1 can realize the retraction of the temperature measuring rod 4 inside the through tube 502 through the winding of the toothed belt 608, so as to facilitate the precise movement of the temperature measuring rod 4 inside the through tube 502. At the same time, by winding the transmission line 3 through the winding drum 7, under the action of the spring, the transmission line 3 can realize self-winding, ensuring the stability of the pull rope of the transmission line 3, thus completing the working principle of the temperature detection device.

[0053] In summary, by setting a connecting component 6 between the transmission line 3 and the temperature measuring rod 4, under the action of the winding unit driving the toothed belt 608 installed on the connecting component 6, the toothed belt 608 is engaged and rotated with the toothed disc 606, so that the toothed disc 606 drives the moving wheels 607 on both sides to rotate through the rotating rod 605, so that the synchronous rotation of multiple groups of moving wheels 607 realizes the movement of the connecting component 6, which makes it easier for the connecting component 6 to drive the temperature measuring rod 4 to move inside the mounting frame component 5, so that the temperature measuring rod 4 can pass through the winding tube 503 at different positions to meet different The temperature of the different windings is detected, and a single set of temperature measuring rods 4 is used to detect the temperature of multiple windings inside the transformer. In addition, multiple sets of toothed belts 608 arranged at equal intervals in a ring shape ensure the telescopic stability of the transmission line 3 during movement, avoiding the problem that the transmission line 3 sags or extends too much during the movement of the temperature measuring rod 4, affecting the movement effect, ensuring the stability of the temperature measuring rod 4 during the mobile temperature measurement process, and solving the problem that the existing winding temperature detection device needs to set temperature measuring devices for the internal windings of the transformer one by one, resulting in high detection costs and increased detection risks.
