Description

Technical Field

[0001] The present invention relates to the technical field of voltage transformers, and in particular to a voltage transformer that is easy to install. Background Art

[0002] Voltage transformers are similar to transformers and are instruments used to transform voltage. However, the purpose of transformers to transform voltage is to facilitate the transmission of electrical energy, so the capacity is very large, and is generally calculated in kilovolt-amperes or megavolt-amperes; while the purpose of voltage transformers to transform voltage is mainly to power measuring instruments and relay protection devices, to measure the voltage, power and electrical energy of the line, or to protect valuable equipment, motors and transformers in the line when a line fault occurs. Therefore, the capacity of voltage transformers is very small, generally only a few volt-amperes or tens of volt-amperes, and the maximum does not exceed one thousand volts.

In addition, the existing voltage transformers are usually connected to the busbar of the transformer, but the existing voltage transformers lack maintenance equipment for the connection between the busbar and the voltage transformer. Since there is usually a large current flowing at the connection between the two, it is very easy to heat up.

An installation box 21 is provided on the outer wall of the maintenance ring 16, and a liquid storage tank 23 is provided inside the installation box 21. A plurality of top grooves 25 are provided on the top of the maintenance ring 16, and a square plate 26 and two dripping tubes 36 are slidably connected to the inner walls of the plurality of top grooves 25, respectively. The square plate 26 is located between the two dripping tubes 36, and the square plate 26 is fixedly connected to the wiping sponge 18. A contact magnet 45 is provided on the outer side of the square plate 26.

[0032] In this embodiment, when the entire voltage transformer 2 needs to be installed during use, the operator can align the bottom of the voltage transformer 2 and insert it into the installation slot 56. When the voltage transformer 2 is inserted into the installation slot 56, the bottom of the voltage transformer 2 will contact and slowly press the sliding member 11 into the sliding cavity 12 along the inclined edge of the sliding member 11 until the bottom of the voltage transformer 2 contacts the installation slot 56.

As the use time increases, in order to prevent the busbar 8 from cracking, the operator can turn on the drive motor 14 to drive the threaded rod 15 to rotate. When the threaded rod 15 rotates, it will drive the maintenance ring 16 to move along the surface of the busbar 8.

A high temperature protection mechanism is provided inside the installation box 21. The high temperature protection mechanism includes a device provided in the installation box 21, the inside of the storage box 46 is connected to the flow tube 47, the middle part of the flow tube 47 is provided with a blocking box 48, the inner side wall of the blocking box 48 is slidably connected with a baffle 49, the outer side wall of the baffle 49 is provided with a pushing magnet 51, the end of the baffle 49 away from the pushing magnet 51 is provided with a tension spring 58, the other end of the tension spring 58 is fixedly connected to the outer side wall of the blocking box 48, the baffle 49 is provided with a through hole 50, the end of the flow tube 47 close to the transmission rod 34 is connected to the covering ring 44, the covering ring 44 is slidably sleeved on the outer side wall of the transmission rod 34 On the side wall, a mounting cross plate is fixedly connected to the outer side wall of the covering ring 44, and the mounting cross plate is fixedly connected to the inner side wall of the mounting box 21. A plurality of outer holes 52 are provided on the transmission rod 34, and a fan 53 is fixedly connected to the end of the transmission rod 34, and a connecting rod 55 is fixedly connected to the end of the fan 53. A throwing box 54 is provided at the end of the connecting rod 55, and a through groove 35 is provided inside the transmission rod 34, and the through groove 35 penetrates into the inside of the throwing box 54, and the end of the through groove 35 away from the throwing box 54 is connected to the outer hole 52, and a side plate 27 is provided inside the mounting box 21, and an electric extension is provided on the side plate 27. The retracting rod 28, the tail of the electric telescopic rod 28 is fixedly connected with a heat absorption sensor 29, the outer side wall of the starting motor 24 is provided with a mounting protrusion, the inner side wall of the mounting protrusion is slidably connected with a push rod 31, the end of the push rod 31 is provided with a friction ring 30, the outer side wall of the transmission rod 34 is fixedly connected with a friction wheel 33, the friction wheel 33 is in sliding contact with the friction ring 30, the outer side of the push rod 31 is sleeved with a compression spring 32, the end of the push rod 31 is connected to the electric telescopic rod 28, the interior of the liquid storage box 23 and the agent storage box 46 are both connected with an elastic feed pipe 9, and the elastic feed pipe 9 passes through the outside of the covering 5.

[0034] In this embodiment, while the transmission rod 34 drives the fan 53 to rotate, it also drives the disc 40 to rotate synchronously. When the disc 40 rotates, the centrifugal force generated causes the trigger magnet 42 to overcome the tension of the tension spring 43 and be thrown to the outside of the disc 40. When the trigger magnet 42 is located on the outside of the disc 40, when it rotates to the right side of the square plate 26 with the disc 40, the trigger magnet 42 located on the outside of the disc 40 is just located on the right side of the contact magnet 45, and the distance between the two becomes closer. Under the action of the magnetic force of attraction, the square plate 26 drives the wiping sponge 18 to move, and when the trigger magnet 42 rotates with the disc 40 to the positive side away from the contact magnet 45, the distance between the two becomes farther, and the magnetic force disappears. At this time, under the elastic force of the pressing spring 20, the wiping sponge 18 returns to its original position. Under the action of the intermittent magnetic force and the elastic force of the pressing spring 20, when the disc 40 rotates, the wiping sponge 18 is driven by the square plate 26 to reciprocate in the slide rail 19. When the square plate 26 drives the wiping sponge 18 to reciprocate, it also drives the dripping tube 36 connected to the wiping sponge 18 to reciprocate. When the dripping tube 36 reciprocates, it intermittently contacts the sliding tube 37. When the dripping tube 36 contacts the sliding tube 37, the sliding tube 37 is first inserted into the insertion hole 57. As the dripping tube 36 continues to push, the sliding tube 37 overcomes the elastic force of the return spring 38 and moves into the liquid storage tank 23, allowing the flow hole 39 originally located outside the liquid storage tank 23 to enter the storage tank. In the liquid tank 23, when the circulation hole 39 enters the liquid storage tank 23, the curing liquid in the liquid storage tank 23 will enter the sliding tube 37 through the circulation hole 39, and then enter the dripping tube 36 through the insertion hole 57 through the sliding tube 37, and finally drip onto the wiping sponge 18 by the dripping tube 36. When the wiping sponge 18 moves with the curing ring 16, it reciprocates and shakes to wipe the curing liquid on the surface of the busbar 8, thereby completing the maintenance process of the busbar 8 and extending the service life of the busbar 8.

[0035] During daily use, if the busbar 8 is found to be overheated and catching fire, the high temperature generated at this time will be detected by the heat absorption sensor 29, and while the alarm is sounded, the electric telescopic rod 28 will be extended to push the friction ring 30 away from the friction wheel 33 (this is the prior art). When the friction ring 30 and the friction wheel 33 are out of contact, the friction force generated between the two disappears. When the power of the starting motor 24 is constant, the friction resistance is reduced. At this time, the starting motor 24 will drive the transmission rod 34 to rotate at high speed. When the transmission rod 34 rotates at high speed, it will drive the fan 53 to rotate at high speed. The fan 53 is driven by the transmission rod 34 to rotate, and the disc 40 is also driven to rotate at a high speed. When the disc 40 rotates at a high speed, the large centrifugal force generated causes the trigger magnet 42 to overcome the tension of the tension spring 43 and be thrown to a greater distance outside the disc 40. At this time, when the trigger magnet 42 rotates to the side of the blocking box 48 with the disc 40, the trigger magnet 42 is just located on the side of the push magnet 51. Under the intermittent repulsive magnetic force, the push magnet 51 pushes the baffle 49 to move intermittently to the right side of the blocking box 48 (refer to Fig. 9 ), when the baffle 49 intermittently moves to the right side of the blocking box 48, it will drive the through hole 50 to intermittently enter the blocking box 48. At this time, the fire extinguishing agent in the storage box 46 will pass through the circulation pipe 47 and then flow into the lower end circulation pipe 47 through the through hole 50. When the transmission rod 34 drives the outer hole 52 to rotate to coincide with the open end of the circulation pipe 47, the fire extinguishing agent transported by the circulation pipe 47 will enter the transmission rod 34 through the outer hole 52, and enter the throwing box 54 through the inclined through groove 35. When the throwing box 54 rotates with the fan 53 through the connecting rod 55, under the action of centrifugal force, the throwing box 54 will throw the fire extinguishing agent inside it to the outside, and mix it with the wind blown out by the fan 53 to extinguish the fire caused by the short circuit, thereby avoiding fire.

[0036] It should be noted that the fire extinguishing agent mentioned in this solution is a dry powder fire extinguishing agent, which can effectively extinguish short-circuit fires.

[0037] It should be noted that the curing liquid in the present technical solution includes silicone oil, polytetrafluoroethylene and graphite powder, etc., which can improve the high temperature resistance of the busbar 8 and can effectively protect the busbar 8 from wear and corrosion.

[0038] It should be noted that, when the fire extinguishing agent in the agent storage box 46 and the curing liquid in the liquid storage box 23 are used up, they can be added through the elastic feeding pipe 9 connected thereto to ensure their use.

[0039] It should be noted that, in this article, relational terms such as first and second, etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device.

[0040] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
