Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of solid-sealed poles, in particular to a solid-sealed pole suitable for a 24KV high-voltage switch cabinet. Background Art
[0002] The sealed pole is formed by embedding the vacuum interrupter and the conductive parts related to the circuit breaker into easily solidified solid insulating materials such as epoxy resin or thermoplastic materials, so that the entire circuit breaker becomes an integral component. The sealed pole is modularly designed with a simple structure and fewer detachable parts, thus having high reliability. At the same time, it has extremely high insulating rod capacity and reduces the size of the circuit breaker, which is conducive to the miniaturization of electrical equipment such as switch cabinets.
[0003] Although the above-mentioned existing technology can solve the corresponding technical problems, it still has certain defects: when the existing sealed pole is used in a high-voltage switch cabinet, the current and voltage flowing through it are high. When the switch is frequently switched repeatedly, the resistance in the sealed pole is large, and the current that cannot pass through will cause loss, converting the electrical energy into heat energy. Therefore, the temperature on the surface of the sealed pole will rise rapidly, and it is easy to cause melting. In order to prevent the high voltage from breaking through the sealed pole due to the melting of the sealed pole, the sealed pole needs to be inspected and replaced after a period of use, and the service life is short and the cost of use is high.

[0006] A further improvement is that a mounting tube is also provided above the main body.
[0007] A further improvement is that: the heat dissipation pipe is provided with a plurality of aluminum heat dissipation fins penetrated by the heat dissipation pipe.
[0008] A further improvement is that a silicone grease layer is also provided on the inner wall of the covering ring.
[0009] A further improvement is that the heat dissipation pipe comprises a copper hollow tube embedded in the outer wall of the covering ring, and an evaporative liquid is arranged in the hollow tube.
[0010] A further improvement is that an opening is provided at one end of the hollow tube away from the covering ring, and a sealing plug is detachably embedded in the opening.
[0011] A further improvement is that a plurality of copper condensing sheets are provided on the inner wall of the hollow tube.
[0012] After adopting the above technical scheme, the beneficial effect of the utility model is as follows: the utility model is provided with a covering ring outside the main body that can efficiently absorb heat, absorbs the heat generated by the main body during use, and outputs it to a number of heat dissipation pipes arranged on the ride, so that the evaporative liquid in the heat dissipation pipe absorbs a large amount of heat and evaporates, and then re-condenses and refluxes, thereby ensuring that the temperature of the main body will not be too high to cause heat melting, thereby making the insulation effect of the main body stronger, not easy to be broken down, and having a longer service life.
