Abstract
Description
Technical Field
[0001] This utility model relates to the field of DC high voltage generator technology, and in particular to a DC high voltage generator with a protective structure. Background Technology
[0002] DC high voltage generators are mainly used to test the insulation strength of electrical equipment, such as zinc oxide surge arresters, magnetic blowout surge arresters, power cables, generators, transformers, switches, etc. By applying DC high voltage, it is observed whether the equipment can withstand the specified voltage without breakdown or flashover, in order to determine whether the insulation performance of the equipment meets the requirements. Measuring the leakage current of electrical equipment under DC high voltage can more sensitively detect problems such as insulation moisture, deterioration, and local defects, such as detecting insulation aging and damage in power cables.
[0003] The announcement number CN220087705U discloses a DC high voltage generator with a protective structure. By adding a support plate, the left and right ends of the voltage multiplier cylinder in the storage tank are pressed against it, preventing the voltage multiplier cylinder from swaying left and right in the storage tank. Several clamping plates on the inner side of the support plate clamp and fix the outer walls of the two sides of the voltage multiplier cylinder to prevent it from swaying up and down and back and forth. This avoids the voltage multiplier cylinder from colliding with the inner wall of the storage tank and causing damage to the voltage multiplier cylinder during the transfer of the DC high voltage generator. The left and right sliding of the support plate is controlled by a rotating wheel and a bidirectional screw structure, which facilitates the placement of the voltage multiplier cylinder.
[0004] This DC high voltage generator with a protective structure can prevent the voltage multiplier cylinder from shaking up and down and back and forth, thus avoiding damage to the voltage multiplier cylinder caused by collision with the inner wall of the storage tank during the transfer of the DC high voltage generator. However, when using the voltage multiplier cylinder, it needs to be taken out of the storage tank and placed in a specific position. During use, the voltage multiplier cylinder is easily tipped over by external force collision, which can lead to damage. Utility Model Content
[0005] To solve the above-mentioned technical problems, this utility model provides a DC high voltage generator with a protective structure.
[0006] This utility model is achieved by the following technical solution: a DC high voltage generator with a protective structure, including a generator, a foam board is provided inside the generator, a pressure multiplier cylinder is provided inside the foam board, a support component is provided on the surface of the pressure multiplier cylinder, and a limit ring is fixedly connected to the surface of the pressure multiplier cylinder;
[0007] The support assembly includes a fixed block, a support plate hinged to the inner wall of the fixed block, a fixed base plate hinged to the end of the support plate away from the fixed block, a hinge seat fixedly connected to one end of the support plate, a movable plate hinged to the inner wall of the hinge seat, and a mounting block hinged to the end of the movable plate away from the hinge seat.
[0008] By using the above technical solution, the mounting block slides downward along the pressure multiplier cylinder, causing the movable plate to rotate on the inner wall of the mounting block and the hinge seat. This causes the hinge seat to expand outward, while simultaneously pushing the support plate to rotate on the inner wall of the fixed block, causing the support plate to expand outward. Then, the fixed base plate is rotated to adjust the angle. Through the contact of the three fixed base plates with the ground, the contact area is increased, thereby improving the stability of the pressure multiplier cylinder when placed, avoiding accidental collisions that could cause the pressure multiplier cylinder to tip over and be damaged, and thus improving the protective effect during use.
[0009] As a further improvement to the above solution, the inner wall of the fixing block is fixedly connected to the surface of the pressure multiplier cylinder.
[0010] As a further improvement to the above solution, the number of the support plate, fixed base plate, hinge seat and movable plate are all set to three.
[0011] With the above technical solution, the three fixed support plates, fixed base plate and movable plate unfold to form a triangle, thereby improving the stability of the support.
[0012] As a further improvement to the above solution, the inner wall of the mounting block is slidably connected to the surface of the pressure multiplier cylinder.
[0013] The angle of the support plate can be adjusted by adjusting the sliding mounting block using the above technical solution, making the operation simple and convenient.
[0014] As a further improvement to the above solution, the mounting block is located at the lower end of the fixing block and at the upper end of the limiting ring.
[0015] The above technical solution uses a limiting ring to limit the position of the mounting block, preventing it from slipping.
[0016] As a further improvement to the above solution, a positioning ring is fixedly connected to the surface of the pressure multiplier cylinder, and a positioning groove is provided on the inner wall of the foam board.
[0017] The above technical solution uses foam board to protect the pressure multiplier cylinder and prevent it from being damaged by collision.
[0018] As a further improvement to the above solution, the surface of the positioning ring contacts the inner wall of the positioning groove, and the size of the positioning ring and the positioning groove are adapted to each other.
[0019] Through the above technical solution, when the positioning ring enters the interior of the positioning groove, it limits the position of the pressure multiplier cylinder, reduces the shaking of the pressure multiplier cylinder, and thus improves the protection effect.
[0020] Compared with the prior art, the beneficial effects of this utility model are as follows:
[0021] This utility model, by setting up a support component, specifically slides the mounting block downwards along the pressure multiplier cylinder, causing the movable plate to rotate on the inner wall of the mounting block and the hinge seat, thus expanding the hinge seat outwards. At the same time, it pushes the support plate to rotate on the inner wall of the fixed block, causing the support plate to expand outwards. Then, the fixed base plate is rotated to adjust the angle. Through the contact of the three fixed base plates with the ground, the contact area is increased, thereby improving the stability of the pressure multiplier cylinder when placed, avoiding accidental collisions that could cause the pressure multiplier cylinder to tip over and be damaged, and thus improving the protective effect during use.
[0022] This utility model incorporates a foam board and a positioning ring. Specifically, the pressure multiplier cylinder is placed inside the foam board, while the positioning ring enters the positioning groove, thus limiting the position of the pressure multiplier cylinder. The foam board prevents the pressure multiplier cylinder from shaking or colliding during transport, thereby improving the protective effect and simplifying the structure. Attached Figure Description

[0030] The present invention will be further described below with reference to the accompanying drawings and specific embodiments. It should be noted that, without conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.
[0031] Example:
[0032] Please combine Figure 1-5 This embodiment of a DC high voltage generator with a protective structure includes a generator 1, a foam board 2 is provided inside the generator 1, a voltage multiplier cylinder 3 is provided inside the foam board 2, a support component 4 is provided on the surface of the voltage multiplier cylinder 3, and a limit ring 5 is fixedly connected to the surface of the voltage multiplier cylinder 3.
[0033] The support assembly 4 includes a fixed block 401, with a support plate 402 hinged to the inner wall of the fixed block 401. A fixed base plate 403 is hinged to the end of the support plate 402 away from the fixed block 401. A hinge seat 404 is fixedly connected to one end of the support plate 402. A movable plate 405 is hinged to the inner wall of the hinge seat 404. An installation block 406 is hinged to the end of the movable plate 405 away from the hinge seat 404. The installation block 406 is slid downward along the pressure multiplier cylinder 3, causing the movable plate 405 to rotate on the inner walls of the installation block 406 and the hinge seat 404, causing the hinge seat 404 to expand outward. At the same time, the support plate 402 is pushed to rotate on the inner wall of the fixed block 401, causing the support plate 402 to expand outward. Then, the fixed base plate 403 is rotated to adjust the angle. The three fixed base plates 403 contact the ground, increasing the contact area, thereby improving the stability of the pressure multiplier cylinder 3 when placed, avoiding accidental collisions that could cause the pressure multiplier cylinder 3 to tip over and be damaged, and thus improving the protective effect during use.
[0034] The inner wall of the fixing block 401 is fixedly connected to the surface of the pressure multiplier cylinder 3.
[0035] The number of support plate 402, fixed base plate 403, hinge seat 404 and movable plate 405 are all three. When not in use, the mounting block 406 is pushed upward, causing the hinge seat 404 and support plate 402 to retract inward for storage.
[0036] The inner wall of mounting block 406 is slidably connected to the surface of pressure multiplier cylinder 3.
[0037] Mounting block 406 is located at the lower end of fixing block 401 and at the upper end of limiting ring 5.
[0038] A positioning ring 6 is fixedly connected to the surface of the pressure multiplier cylinder 3, and a positioning groove 7 is opened on the inner wall of the foam board 2. When the pressure multiplier cylinder 3 is placed inside the foam board 2, the positioning ring 6 enters the positioning groove 7, which plays a limiting role for the pressure multiplier cylinder 3. The foam board 2 prevents the pressure multiplier cylinder 3 from shaking and colliding during transportation, thereby improving the protection effect.
[0039] The surface of the positioning ring 6 contacts the inner wall of the positioning groove 7, and the dimensions of the positioning ring 6 and the positioning groove 7 are compatible.
[0040] The implementation principle of a DC high-voltage generator with a protective structure in this embodiment is as follows: During use, the voltage multiplier cylinder 3 is removed, and the mounting block 406 is slid downwards along the voltage multiplier cylinder 3, causing the movable plate 405 to rotate on the inner walls of the mounting block 406 and the hinge seat 404. This causes the hinge seat 404 to expand outwards, simultaneously pushing the support plate 402 to rotate on the inner wall of the fixed block 401, causing the support plate 402 to expand outwards. Then, the fixed base plate 403 is rotated to adjust the angle, and the three fixed base plates 403 contact the ground, increasing the connection... The increased contact area improves the stability of the pressure multiplier 3 during placement, preventing accidental collisions that could cause it to tip over and be damaged, thus enhancing its protective effect during use. When not in use, the mounting block 406 is pushed upwards, causing the hinge seat 404 and support plate 402 to retract inwards for storage. Then, the pressure multiplier 3 is placed inside the foam board 2, while the positioning ring 6 enters the positioning groove 7, limiting the position of the pressure multiplier 3. The foam board 2 prevents the pressure multiplier 3 from shaking or colliding during transport, thereby improving the protective effect.
[0041] The above embodiments are merely preferred embodiments of this utility model and should not be construed as limiting the scope of protection of this utility model. Any non-substantial changes and substitutions made by those skilled in the art based on this utility model shall fall within the scope of protection claimed by this utility model.
