[0002] The assembled converter transformer is a device that combines a converter and a transformer and is used for direct current transmission in power systems. It consists of multiple modular units and can be assembled and disassembled according to actual needs. The assembled converter transformer is composed of multiple modular units and can be flexibly assembled and disassembled according to actual needs, which makes installation and maintenance more convenient and can be expanded or reduced according to grid needs. At the same time, each modular unit is independent and has its own protection and control system. The assembled converter transformer adopts a modular design, which can make more effective use of space. Compared with traditional converter transformers, it is more compact in footprint and suitable for places with limited space. However, when using the assembled converter transformer, an air pump is required to create a vacuum environment in the vacuum tank and then fill it with insulating oil for insulating oil protection. During this operation, insulating oil and other dust in the air will remain inside the vacuum tank. Manual cleaning is more troublesome and requires disassembling the vacuum tank for cleaning, which is inefficient and inconvenient to operate. In the long run, it will have an adverse effect on the service life of the vacuum tank.

[0003] In view of the above problems, a special vacuum tank for assembled converter transformer is proposed to solve the above problems. Utility Model Content

[0022] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0023] In order to further understand the content of the present invention, the present invention is described in detail with reference to the accompanying drawings.

[0024] Combine Figure 1 A vacuum tank dedicated to an assembled converter transformer includes a vacuum tank mechanism 5, which is arranged inside an outer protective shell 1 for providing vacuum environment protection for the converter transformer.

[0025] The present invention will be further described below with reference to the embodiments.

[0026] See also Figure 2-Figure 5The vacuum tank mechanism 5 includes a vacuum tank body 51 fixedly connected to the inner wall of the outer protective shell 1, a sliding groove 53 is opened on the inner wall of the vacuum tank body 51, an electromagnet 54 is arranged inside the vacuum tank body 51, and the electromagnet 54 is composed of a plurality of small sections. A cleaning component 52 for cleaning the inner wall of the vacuum tank body 51 is arranged inside the vacuum tank body 51, and the cleaning component 52 includes a cleaning plate 521, a magnetic block 522 is fixedly connected to the bottom surface of the cleaning plate 521, a brush 523 is fixedly connected to one side of the cleaning plate 521, and sliding plates 524 are fixedly connected on both sides of the cleaning plate 521. A mounting plate 525 is fixedly connected to one side of the sliding plate 524. The mounting plate 525 is slidably connected to the inside of the sliding groove 53, and a clamping block 527 is fixedly connected to one side of the mounting plate 525. The clamping block 527 is clamped with the inside of the sliding groove 53, through the vacuum tank body 51 and the sliding groove 5 3. The arrangement of the cleaning plate 521, the brush 523, the sliding plate 524 and the mounting plate 525 can be such that when injecting insulating oil, the multi-segment electromagnet 54 can be energized, which is conducive to the repulsive force with the magnetic block 522 to drive the cleaning plate 521 to move upward. Since the mounting plate 525 slides inside the sliding groove 53 and the clamping block 527 is engaged with the inside of the sliding groove 53, it prevents the cleaning plate 521 from detaching during movement. During the movement, the brush 523 cleans the inner wall of the vacuum tank body 51. After the cleaning plate 521 moves to a suitable position, the electrical properties of the electromagnet 54 are changed, and the cleaning plate 521 is fixed to the inner wall of the vacuum tank body 51. After the insulating oil is discharged, the electrical properties of the electromagnet 54 are changed. During the falling and sliding process of the cleaning plate 521, the brush 523 is used to clean the insulating oil adhered to the inner wall of the vacuum tank body 51.

[0027] The mounting plate 525 is internally connected to a roller 526 that is rotatably connected thereto. The roller 526 runs through one side of the mounting plate 525 . By setting the roller 526 , the rolling of the roller 526 can be utilized to reduce friction during the movement of the cleaning plate 521 , thereby facilitating the movement of the cleaning plate 521 .

[0028] The inner wall of the outer protective shell 1 is fixedly connected to a mounting base plate 15, and the upper surface of the mounting base plate 15 is fixedly connected to a winding body 6. The height of the winding body 6 is lower than the maximum height to which the cleaning plate 521 can rise. Through the arrangement of the mounting base plate 15 and the winding body 6, the basic functions of the converter transformer are realized. At the same time, when filling the insulating oil, the winding body 6 is ensured to be completely immersed while the brush 523 is prevented from being soaked in the insulating oil.

[0029] An oil storage tank 4 is arranged above the outer protective shell 1, and a bracket 41 is fixedly connected to the bottom of the oil storage tank 4, and the bracket 41 is fixedly connected to the upper surface of the outer protective shell 1. An oil inlet pipe 42 is fixedly connected to the bottom of the oil storage tank 4, and the oil inlet pipe 42 is connected to the interior of the vacuum tank body 51. An oil inlet pump 43 is fixedly connected to the outside of the oil inlet pipe 42. Through the arrangement of the oil storage tank 4, the bracket 41, the oil inlet pipe 42 and the oil inlet pump 43, the interior of the vacuum tank body 51 can be filled with insulating oil in a timely manner.

[0030] A vacuum pump 12 is fixedly connected to one side of the outer protective shell 1, and a vacuum monitor 2 is fixedly connected to one side of the outer protective shell 1. Through the setting of the vacuum pump 12 and the vacuum monitor 2, the inside of the vacuum tank body 51 is adjusted to the required vacuum state, and the vacuum monitor 2 is used to timely monitor the vacuum degree of the vacuum tank body 51.

[0031] An oil drain pipe 13 is fixedly connected to one side of the outer protective shell 1, and an oil outlet pump 14 is fixedly connected to the outside of the oil drain pipe 13. Through the arrangement of the oil drain pipe 13 and the oil outlet pump 14, the insulating oil in the vacuum tank body 51 can be extracted for easy cleaning.

[0032] A connecting frame 11 for assembling the converter transformer is fixedly connected to the bottom surface of the outer protective shell 1. The arrangement of the connecting frame 11 facilitates the assembly of the converter transformer.

[0033] A cooling component 3 for cooling the outer protective shell 1 is provided on one side of the outer protective shell 1. The cooling component 3 includes a side box 31 fixedly connected to one side of the outer protective shell 1. An air blower 32 is provided inside the side box 31. Through the setting of the side box 31 and the air blower 32, the winding body 6 can be cooled during operation.

[0034] Specifically, when insulating oil needs to be injected into the vacuum tank body 51, the electromagnet 54 is energized, and the repulsive force between the electromagnet 54 and the magnetic block 522 is used to drive the cleaning plate 521 to move under the rolling action of the roller 526, so that the cleaning plate 521 is higher than the upper surface of the insulating oil. At this time, the converter transformer is insulated and protected. When the inner wall of the vacuum tank body 51 needs to be cleaned after the insulating oil is discharged, the cleaning plate 521 is driven to slide downward along the inner wall of the vacuum tank body 51 by energizing the electromagnet 54 and the magnetic block 522 and the gravity of the cleaning plate 521 itself. During this process, the inner wall of the vacuum tank body 51 is cleaned by the brush 523, thereby achieving the purpose of facilitating the cleaning of the inner wall of the vacuum tank body 51 after the insulating oil is injected.
