[0024] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present utility model.

[0025] Please refer to Figures 1-5, An embodiment provided by the present utility model: A high-voltage capacitor with high temperature resistance and high elevation, including a box body 1 and a protection mechanism 3. A connector 2 is arranged on the front surface of the box body 1, and a protection mechanism 3 is arranged on the right side of the connector 2. A filling layer 301 is arranged inside the box body 1, and a lining 302 is arranged inside the filling layer 301.

[0026] Specifically, the filling layer 301 is made of silica gel material, and the lining 302 is made of silicone resin material. The filling layer 301 is closely attached to the lining 302. The silica gel filling layer 301 can maintain stability at high temperatures, and the silicone resin lining 302 has good electrical insulation and chemical resistance and can withstand high voltages.

[0027] Specifically, a heat-conducting liquid 303 is arranged inside the lining 302, and the heat-conducting liquid 303 fills the inside of the lining 302. The heat-conducting liquid 303 is silicone oil. Silicone oil is a commonly used heat-conducting liquid 303, which has good thermal stability and insulation, and a relatively wide working temperature range. It is usually used in the heat dissipation system of electronic devices.

[0028] Specifically, a capacitor body 304 is arranged at the bottom of the lining 302, and a partition pad 305 is arranged inside the capacitor body 304. The partition pads 305 are evenly distributed at the four corners of the capacitor body 304. The capacitor body 304 is separated by using the partition pads 305 to increase the contact surface with the heat-conducting liquid 303 and improve the cooling efficiency.

[0029] Specifically, a protective shell 306 is arranged on the top of the box body 1. A filter screen 307 is arranged on the front surface of the protective shell 306, and a fan 308 is arranged on the back surface of the protective shell 306. A heat dissipation box 309 is arranged inside the protective shell 306. The fan 308 works to drive air flow, and the filter screen 307 filters the air to prevent impurities from affecting the operation of internal parts. The air passes through the heat dissipation box 309 to take away heat for cooling.

[0030] Specifically, a cooler 310 is arranged on the right side of the heat dissipation box 309, a solenoid valve 311 is arranged on the left side of the heat dissipation box 309, a water pump 312 is arranged on the left side of the solenoid valve 311. One end of the water pump 312 is connected to a cooling pipe 313, and the other end of the cooling pipe 313 is connected to the heat dissipation box 309. When the ambient temperature is relatively high, the cooler 310 works to accelerate the cooling of the coolant, and the water pump 312 transfers the cooling liquid through the cooling pipe 313 into the box body 1 to cool the heat-conducting liquid 303.

[0031] Specifically, a temperature control switch 314 is arranged on the surface of the lining 302. Multiple groups of temperature control switches 314 are arranged. The temperature control switch 314 is connected to the solenoid valve 311. The temperature control switch 314 detects the temperature of the heat-conducting liquid 303. When the temperature is too high, the solenoid valve 311 at the heat dissipation box 309 is closed, and the solenoid valve 311 at the cooler 310 is opened to quickly cool the heat-conducting liquid 303 and ensure the stability of the capacitor body 304 at high temperatures.

[0032] Working principle: First, install and fix the capacitor. During use, the temperature control switch 314 detects the temperature of the heat-conducting liquid 303. When the temperature is too high, the solenoid valve 311 at the radiator box 309 closes, and the solenoid valve 311 at the cooler 310 opens to quickly cool down the heat-conducting liquid 303, ensuring the stability of the capacitor body 304 at high temperatures. The cooler 310 works to accelerate the cooling of the coolant, and the water pump 312 transfers the refrigerant through the cooling pipe 313 into the box body 1 to cool down the heat-conducting liquid 303. At the same time, the fan 308 works to drive air flow, and the filter screen 307 filters the air to prevent impurities from affecting the operation of internal components. The air passes through the radiator box 309 to take away heat and cool down. The partition pad 305 separates the capacitor body 304 to increase the contact surface with the heat-conducting liquid 303 and improve the cooling efficiency. Moreover, the silicone filling layer 301 can maintain stability at high temperatures, and the silicone resin lining 302 has good electrical insulation and chemical resistance and can withstand a relatively high voltage.

[0033] The above are only the embodiments of the present invention, and common knowledge such as the specific structures and characteristics known in the solutions is not described in detail here. For those skilled in the art, it is obvious that the present invention is not limited to the details of the above exemplary embodiments, and can be implemented in other specific forms without departing from the spirit or basic characteristics of the present invention. Therefore, from any point of view, the embodiments should be regarded as exemplary and non-limiting. The scope of the present invention is defined by the appended claims rather than the above description. Therefore, all changes falling within the meaning and scope of the equivalent elements of the claims are intended to be included in the present invention.
