Description

Technical Field

[0001] This utility model relates to the field of voltage booster technology, specifically a modular power frequency high voltage booster. Background Technology

[0002] Step-up transformers are essential testing equipment for a wide range of users, including power plants, power distribution systems, and research institutions. They are used to conduct insulation strength tests on various electrical products, equipment, and insulating materials under specified voltages, assess the insulation level of products, detect insulation defects in the tested items, and measure their ability to withstand overvoltage.

[0003] Typically, a sufficiently large creepage distance must be maintained on the high-voltage side of a step-up transformer. The higher the voltage, the more stringent the requirements. As the voltage increases, the creepage distance increases significantly. To avoid the risk of flashover on the insulation surface at higher voltages, the distance between supporting equipment needs to be greatly increased, which also increases the overall size of the testing equipment, significantly impacting ease of use and greatly increasing production costs and transportation difficulties.

[0004] To increase creepage distance, many step-up transformers use insulating materials with high dielectric constants to make sleeves on the high-voltage side. However, the internal space of testing instruments is usually limited, and adding insulating sleeves to increase creepage distance often requires more space to accommodate longer insulation paths, which brings difficulties in installation and layout. Moreover, longer insulating sleeves are more prone to deformation or damage when subjected to external forces or vibrations. During transportation, if subjected to bumps or collisions, problems such as bending and cracking may occur, affecting their insulation performance. Therefore, we propose a modular power frequency high-voltage step-up transformer. Utility Model Content

[0005] The purpose of this invention is to provide a modular power frequency high voltage booster to address the issues raised in the background art where adding insulating sleeves to increase creepage distance often requires more space to accommodate longer insulation paths, leading to installation and layout difficulties. Furthermore, longer insulating sleeves are more prone to deformation or damage under external forces or vibrations. During transportation, bumps or collisions can also cause bending, cracking, and other problems, affecting their insulation performance.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a modular power frequency high voltage booster, comprising:

[0007] The booster body has a connector sleeve fixedly connected to its upper part, and a high-voltage connector is installed inside the connector sleeve. An electrical waterproof terminal is installed above the high-voltage connector.

[0008] A snap-fit ​​plate is installed at the connection between the connector sleeve and the high-pressure connector, and positioning bolts are installed on both sides of the snap-fit ​​plate;

[0009] A connector is installed below the booster body, and a coupling is installed above the connector.

[0010] Preferably, the connector sleeve is fixedly connected to the booster body, and the center points of the connector sleeve and the booster body are on the same vertical line.

[0011] Preferably, the connector is fixedly connected to the booster body, and the positions of the connector and the plug correspond to each other.

[0012] Preferably, the high-pressure connector engages with the booster body, and the high-pressure connector and the booster body are detachably connected.

[0013] Preferably, the connector sleeve is fixedly connected to the snap-fit ​​plate, and the snap-fit ​​plate is fixed relative to the connector sleeve by positioning bolts.

[0014] Preferably, the positioning bolt further comprises:

[0015] A limiting rotating plate is installed on one side above the positioning bolt, and a positioning rotating shaft is installed on one side inside the limiting rotating plate.

[0016] Preferably, the limiting rotating plate is rotatably connected to the positioning rotating shaft, and the limiting rotating plate is perpendicular to the positioning bolt.

[0017] Compared with the prior art, this utility model provides a modular power frequency high voltage booster, which has the following advantages:

[0018] This invention divides the voltage booster into two parts by differentiating modules. The high-voltage part is cast with epoxy resin. The high-voltage side cable is connected to the plug at the bottom of the high-voltage connector, and then the high-voltage connector drives the cable to connect tightly to the plug of the voltage booster body. This way, the connection between the high-voltage side cable and the voltage booster is placed inside the epoxy resin body, which effectively increases the creepage distance, reduces the overall size of the voltage booster, meets the mechanical strength requirements, and also provides better waterproof, dustproof, and stain-proof effects. This avoids the need for adding insulating sleeves to increase the creepage distance, which often requires more space to accommodate longer insulation paths, leading to installation and layout difficulties. Furthermore, longer insulating sleeves are more prone to deformation or damage under external forces or vibrations. During transportation, bumps or collisions may also cause bending or cracking, affecting its insulation performance. Attached Figure Description

Connector 7 is fixedly connected to booster body 1, and connector 8 corresponds to connector 7. The booster is divided into two parts by distinguishing modules. The high-voltage part is made of epoxy resin. The high-voltage side cable is connected to connector 7 at the bottom of high-voltage connector 5, and then high-voltage connector 5 drives the cable to be tightly connected to connector 8 of booster body 1. In this way, the connection part of high-voltage side cable and booster is placed inside epoxy resin body, which effectively increases the creepage distance, reduces the size of the overall booster, meets the mechanical strength requirements, and also has better waterproof, dustproof and dirt-proof effects.

[0026] Please see Figure 1 and 4A modular power frequency high voltage booster includes: a limiting rotating plate 9, which is installed on one side above the positioning bolt 3; a positioning rotating shaft 10 is installed on one side inside the limiting rotating plate 9; the limiting rotating plate 9 and the positioning rotating shaft 10 are rotatably connected, and the limiting rotating plate 9 and the positioning bolt 3 are perpendicular to each other; the snap-fit ​​plate 2 facilitates the mutual snapping of the high voltage connector 5 and the booster body 1; the positioning bolt 3 can fix the snap-fit ​​plate 2 and the booster body 1; the limiting rotating plate 9 can rotate in cooperation with the positioning rotating shaft 10; after rotation, the limiting rotating plate 9 can limit the positioning bolt 3 to prevent loosening.

[0027] Working Principle: When using this modular power frequency high voltage booster, the entire booster adopts a modular split structure, consisting of a high-voltage connector 5 and the booster body 1. The high-voltage cable is located in the middle of the high-voltage connector 5, and connects to the connector 8 at the bottom of the high-voltage connector 5. The high-voltage connector 5 then drives the cable to connect to the booster body 1, where it is tightly connected to the plug 7. When the high-voltage connector 5 and the booster body 1 are separated, the plug 7 and connector 8 also separate. The high-voltage cable passes through the high-voltage connector 5 and is deeply embedded inside the booster, thus ensuring sufficient creepage distance. The clamping plate 2 facilitates high-voltage... The interlocking of the crimp connector 5 and the booster body 1, along with the fixing bolts 3, allows the crimping plate 2 and the booster body 1 to be fixed together. The limiting rotating plate 9 can rotate in conjunction with the positioning rotating shaft 10. After rotation, the limiting rotating plate 9 can limit the positioning bolts 3 to prevent loosening. This booster has a small size and compact structure. The two modules can be tightly combined, occupying little space. Under the premise of ensuring sufficient creepage distance, the modular high-voltage booster can achieve efficient voltage boosting without occupying too much space. This is the working principle of the modular power frequency high-voltage booster.
