Description

Technical Field

[0001] This utility model specifically relates to the field of DC high voltage generator technology, and more specifically to a DC high voltage generator with a heat dissipation component. Background Technology

[0002] DC high voltage generators are mainly used to conduct withstand voltage tests on the insulation performance of electrical equipment. In power systems, the insulation materials of equipment such as power cables, capacitors, and high voltage switches are subjected to high voltage. They can also be used to measure the leakage current of electrical equipment under DC high voltage. When a DC high voltage is applied to electrical equipment, a certain current will flow through the insulating medium. This current is the leakage current.

[0003] A DC high-voltage generator primarily produces a stable DC high voltage by transforming and processing a series of power frequency AC power supplies. Generally, a transformer is first used to boost the input low-voltage power frequency AC power to a higher AC voltage. Then, a rectifier circuit converts the AC voltage to DC voltage. Finally, filtering and other processes are used to make the output DC voltage more stable and smooth, meeting the requirements of different high-voltage tests.

[0004] However, in practice, it has been noted that the rectifier components in a DC high-voltage generator generate a lot of heat during operation. Since the internal electronic components are generally installed in the base, the heat dissipation holes on the side alone cannot meet the requirements for long-term use. The heat dissipation holes on the side can provide good heat dissipation for electronic components near the edge, but the heat dissipation effect is worse for electronic components further in the center. Prolonged high temperatures will damage the electronic components, thereby reducing the service life of the DC high-voltage generator. Utility Model Content

[0005] The purpose of this invention is to provide a DC high-voltage generator with a heat dissipation component. By controlling the air vents located at the top and bottom of the chassis, and in conjunction with a cooling fan located at the bottom, airflow is used to carry away heat from top to bottom. Furthermore, a foldable heat dissipation mechanism is located at the bottom of the chassis for easy storage of the heat dissipation structure. This addresses the technical problems mentioned in the background section.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A DC high-voltage generator with a heat dissipation component includes a control chassis, a heat dissipation mechanism at the bottom of the control chassis, and the control chassis is connected to a high-voltage cylinder via a high-voltage line and a grounding line.

[0008] The heat dissipation mechanism includes a support base that slides with the control chassis, and both ends of the support base are fixedly connected to end connecting covers. Each end connecting cover is movably connected to a flip frame, and a cooling fan is symmetrically fixedly connected to the flip frame.

[0009] As a further technical solution of this utility model, the control box has a rectangular array of limit grooves on both sides, and the support base includes a U-shaped seat that is sleeved on the bottom of the control box, and the U-shaped seat has positioning protrusions on both sides inside that correspond to the limit grooves.

[0010] The positioning protrusion and the U-shaped seat are integrated into one piece, and the positioning protrusion slides in conjunction with the limiting groove.

[0011] As a further technical solution of this utility model, the end connecting cover includes a hollow cover plate fixedly connected to both ends of the U-shaped seat. The end of the hollow cover plate is threaded with a locking bolt, and the other side of the hollow cover plate is symmetrically provided with a grooved slide rail that cooperates with the flipping frame.

[0012] As a further technical solution of this utility model, the flipping frame includes a double-hole bracket, both sides of which are integrally provided with movable sliders, and the end of the movable slider away from the double-hole bracket is slidably connected to the groove slide rail.

[0013] As a further technical solution of this utility model, the double-hole bracket has symmetrical through holes, and a protective mesh is embedded in each through hole, and a cooling fan is fixedly connected to the double-hole bracket on the side of each protective mesh.

[0014] As a further technical solution of this utility model, the bottom of the control box is fixedly connected with a fixed baffle in a rectangular array, and the side of the fixed baffle is integrally provided with a fixed shaft. Both ends of the double-hole bracket are integrally provided with top ear plates.

[0015] The fixing shaft on the side of the fixing baffle is rotatably connected to the double-hole bracket.

[0016] As a further technical solution of this utility model, the top and bottom of the control box are provided with air vents, and there are multiple air vents.

[0017] Compared with the prior art, the beneficial effects of this utility model are:

[0018] This utility model, through the sliding connection between the movable slider and the grooved slide rail and the rotational connection between the top ear plate and the fixed shaft, allows the support base to move upward, which in turn drives the flip frame to be stored under the control box, making it convenient to carry the DC high voltage generator.

[0019] In this invention, air vents are provided at the top of the control chassis and at the bottom of the air vent. Together with the cooling fan located at the bottom of the control chassis, airflow is made to flow from top to bottom, thereby ensuring that the heat dissipation effect of electronic components in any position in the control chassis is consistent, thus improving the heat dissipation effect of the DC high voltage generator.

[0020] In this invention, the U-shaped base and the perforated cover plate work together to allow the U-shaped base to slide under the control box. When stored, the cooperation between the U-shaped base and the perforated cover plate can protect the cooling fan on the side of the flip frame. Attached Figure Description

Detailed Implementation

[0030] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0031] Please see Figure 1-7 This utility model embodiment provides a DC high voltage generator with a heat dissipation component, including a control box 1, a heat dissipation mechanism at the bottom of the control box 1, and the control box 1 is connected to the high voltage cylinder 7 through a high voltage line 2 and a grounding line 3.

[0032] The heat dissipation mechanism includes a support base 4 that slides with the control chassis 1, and both ends of the support base 4 are fixedly connected to end connecting covers 5. Each end connecting cover 5 is movably connected to a flip frame 6, and a cooling fan 8 is symmetrically fixedly connected to the flip frame 6.

[0033] In this embodiment, the control box 1 has a rectangular array of limit grooves 11 on both sides, and the support base 4 includes a U-shaped seat 41 sleeved under the control box 1, and the U-shaped seat 41 has positioning protrusions 42 on both sides inside the U-shaped seat 41 that correspond to the limit grooves 11.

[0034] The positioning protrusion 42 and the U-shaped seat 41 are integrated, and the positioning protrusion 42 slides in conjunction with the limiting groove 11.

[0035] In this embodiment, the end connecting cover 5 includes a hollow cover plate 51 that is fixedly connected to both ends of the U-shaped seat 41. The end of the hollow cover plate 51 is threaded with a locking bolt 52, and the other side of the hollow cover plate 51 is symmetrically provided with a grooved slide rail 53 that cooperates with the flip frame 6.

[0036] In this embodiment, the flipping frame 6 includes a double-hole bracket 61, and both sides of the double-hole bracket 61 are integrally provided with movable sliders 64, and the end of the movable slider 64 away from the double-hole bracket 61 is slidably connected to the groove slide rail 53.

[0037] Furthermore, the double-hole bracket 61 has symmetrical through holes, and a protective mesh 63 is embedded in each through hole. Each protective mesh 63 has a cooling fan 8 fixedly connected to the double-hole bracket 61 on its side.

[0038] Furthermore, the bottom of the control box 1 is fixedly connected with fixed baffles 13 in a rectangular array, and the side of the fixed baffles 13 is integrally provided with fixed shafts 14. Both ends of the double-hole bracket 61 are integrally provided with top ear plates 62.

[0039] The fixing shaft 14 on the side of the fixing baffle 13 is rotatably connected to the double-hole bracket 61.

[0040] Furthermore, the top and bottom of the control box 1 are both provided with air vents 12, and there are multiple air vents 12.

[0041] By adopting the above technical solution, when in use, loosen the locking bolt 52 and move the U-shaped seat 41 downward. The positioning protrusion 42 on the inner side of the U-shaped seat 41 slides and engages with the limiting slide groove 11, thereby causing the U-shaped seat 41 to drive the hollow cover plate 51 to move downward. Due to the rotational connection between the fixed shaft 14 and the top ear plate 62, and in conjunction with the sliding connection between the moving slider 64 and the groove slide rail 53, the flip frame 6 fits against the side of the hollow cover plate 51. Through the mutual cooperation of the folding structure, the heat dissipation structure can be stored after use, making it easy to carry. The heat dissipation fan 8 on the side of the double hole bracket 61 will carry away the heat inside the control box 1. The airflow flows from top to bottom, ensuring that the heat dissipation effect of electronic components in any position in the control box 1 is consistent, thereby improving the heat dissipation effect.

[0042] In this embodiment, a current-limiting resistor 71 is fixedly connected to the end of the high-pressure cylinder 7, and the end of the current-limiting resistor 71 away from the high-pressure cylinder 7 is fixedly connected to a microammeter 72.

[0043] In this embodiment, a high-voltage generating module is installed in the control box 1. The high-voltage generating module includes a transformer, a rectifier circuit, a filter circuit, an adjustment circuit, and a control circuit. The adjustment circuit is electrically connected to the control circuit through wires, and the control circuit is electrically connected to the transformer, the rectifier circuit, and the filter circuit through wires.

[0044] More specifically, the low-voltage AC power is stepped up by a transformer. The stepped-up high-voltage AC power is then processed by a rectifier circuit and a filter circuit to convert the high-voltage AC power into high-voltage DC power. Finally, the high-voltage DC power is transmitted to the high-voltage cylinder 7 through the high-voltage line 2.

[0045] The working principle of this utility model is as follows: In use, first loosen the locking bolt 52, then move the U-shaped seat 41 downwards. The positioning protrusion 42 on the inner side of the U-shaped seat 41 slides into the limiting groove 11, causing the U-shaped seat 41 to move the hollow cover plate 51 downwards. Due to the rotational connection between the fixed shaft 14 and the top ear plate 62, and the sliding connection between the moving slider 64 and the grooved slide rail 53, the flip frame 6 fits against the side of the hollow cover plate 51. At this time, the cooling fan 8 on the side of the double-hole bracket 61 will cool the control box. Heat is carried out from the inside of the control box 1. Airflow enters and exits from the inside of the air outlet 12 from top to bottom, improving the heat dissipation effect on the inside of the control box 1. After use, push the bottom of the flip frame 6 to move inward. Through the sliding connection between the sliding slider 64 and the groove slide rail 53 and the rotational engagement between the fixed shaft 14 and the top ear plate 62, the flip frame 6 is stored under the control box 1. The support base 4 slides upward to store the DC high voltage generator, making it easy to carry the DC high voltage generator.
