Description

Technical Field

[0001] The utility model belongs to the technical field of water resistance structures, and particularly relates to a high-voltage water resistance. Background Art

[0002] At present, the main types of devices for high-voltage loads are mainly solid resistors and water resistors. The solid resistor is mainly made of a contactor and resistance wires. By closing the contactor, the number of parallel-connected resistance wires is changed to obtain a specified resistance value. The water resistor mainly consists of a resistance cylinder, electrode columns arranged at both ends of the resistance cylinder, and electrolyte filled in the resistance cylinder. The external installation dimensions and resistance values of the existing water resistors are usually fixed. When water resistors with different resistance values are needed, only water resistors of different models can be selected, and a water resistor with an external dimension adapted to the installation part needs to be selected. This results in a large number of specifications and models of water resistors, which is not convenient for production and application. Summary of the Utility Model

[0003] To solve the deficiencies of the existing technology, the utility model provides a high-voltage water resistance, which can adapt to different installation conditions caused by changes in the distance between electrode plates, and can change the resistance value of the water resistance by replacing the electrolyte to meet the use requirements.

[0004] To achieve the purpose of the utility model, the following scheme is proposed:

[0005] A high-voltage water resistance includes: a resistance cylinder, end caps, and electrode rods.

[0006] The resistance cylinder has a circular tube structure;

[0007] There are two end caps, which are detachably arranged at both ends of the resistance cylinder. The end caps are hermetically connected to the resistance cylinder, and the inside of the resistance cylinder and the end caps at both ends are used to fill the electrolyte;

[0008] There are two electrode rods, which are respectively passed through the two end caps. The front end of the electrode rod extends to a predetermined length inside the resistance cylinder, and the end of the electrode rod protrudes from the outside of the corresponding end cap by a predetermined length. When installed, the water resistance is arranged between two electrode plates of the device, and the ends of the two electrode rods are respectively passed through the two electrode plates. The predetermined length that the electrode rod protrudes from the outside of the end cap is greater than the thickness of the electrode plate.

[0009] The beneficial effect of the utility model is that by providing detachable end caps, the electrolyte inside the water resistance can be replaced, thereby changing the resistance value of the water resistance, enabling the same water resistance to adapt to different use requirements, and the electrode rod can adapt to the change in the distance between the electrode plates by using a hole-shaft connection method with the electrode plate, meeting the requirements of different installation conditions.

[0013] Markings in the figure: resistance cylinder - 1, end cap - 2, electrode rod - 3, ball head - 31, mounting nut - 4. Specific embodiments

[0014] To make the objectives, technical solutions and advantages of the embodiments of the present utility model clearer, the following will describe the embodiments of the present utility model in detail with reference to the accompanying drawings. However, the embodiments described in the present utility model are only a part of the embodiments of the present utility model, not all of the embodiments.

[0015] As Figure 1 、 Figure 2 shown, a high - voltage water resistor includes: a resistance cylinder 1, an end cap 2 and an electrode rod 3.

[0016] Specifically, the resistance cylinder 1 has a circular tube structure.

[0017] Specifically, the number of end caps 2 is two, which are detachably arranged at both ends of the resistance cylinder 1. The connection between the end cap 2 and the resistance cylinder 1 is a sealed connection. The interior of the resistance cylinder 1 and the end caps 2 at both ends are used to fill electrolyte.

[0018] Specifically, the number of electrode rods 3 is two, which respectively penetrate through the two end caps 2. The front end of the electrode rod 3 extends into the interior of the resistance cylinder 1 by a predetermined length to increase the contact area with the electrolyte. The end of the electrode rod 3 protrudes from the outside of the corresponding end cap 2 by a predetermined length. During installation, the water resistor is arranged between two electrode plates of the device. The ends of the two electrode rods 3 respectively penetrate through the two electrode plates. The predetermined length by which the electrode rod 3 protrudes from the outside of the end cap 2 is greater than the thickness of the electrode plate, so as to adapt to different installation intervals of the two electrode plates, thereby increasing the adaptability and practicability of the water resistor.

[0019] More specifically, the resistance cylinder 1 is made of 304 stainless steel, and the electrode rod 3 is made of H62 copper.

[0020] The water resistor conducts electricity by relying on the electrolyte ions dissolved in water. The commonly used electrolyte solution is made by dissolving distilled water and electrolytic powder. The electrolyte solution is injected into the resistor cylinder 1, and the front end of the electrode rod 3 is immersed in the electrolyte solution, thus forming a water resistor. When different resistances are needed, only the end cover 2 needs to be removed from the resistor cylinder 1 and the electrolyte solution with different concentrations is replaced. There is no need to prepare water resistors with various resistance values, which can not only effectively reduce the production management cost, but also be more convenient to use.

[0021] Preferably, as Figure 2 shown, the rear end of at least one electrode rod 3 is a screw structure, and at least two mounting nuts 4 are provided. During installation, the electrode rod 3 passes through the corresponding electrode plate, and both sides of the electrode plate are tightened by the mounting nuts 4. This connection structure can not only fix the water resistor, but also adjust the distance between the water resistor and the electrode plate to adapt to different installation environments.

[0022] Preferably, as Figure 1 shown, the front ends of the electrode rods 3 are all provided with ball heads 31 to facilitate passing a larger current.

[0023] Preferably, both ends of the resistor cylinder 1 have an external thread structure for connecting the end cover 2 to facilitate the disassembly and assembly of the end cover 2.

[0024] Further preferably, a sealing ring is provided between the end face of the resistor cylinder 1 and the end cover 2 to achieve the purpose of sealed connection, thereby preventing the leakage of the electrolyte solution.

[0025] The above are only the preferred embodiments of the present invention and do not represent the only or limit the present invention. Those skilled in the art should understand that without departing from the scope of the present invention, various changes or equivalent replacements made to the present invention all fall within the scope of protection of the present invention.
