Abstract

The invention relates to the technical field of power system capacitors and particularly relates to a cooling and heat radiation structure of a capacitor, which comprises a cooling mechanism, a heat radiation mechanism and multiple parallel capacitor elements, wherein the capacitor element is coated with a layer of insulating paper; the cooling mechanism comprises a water tank and a water pipe; one side of the water tank is communicated with the water pipe, and the other side of the water tank is provided with a sliding piston; the water pipe is wound on the capacitor element coated by the insulating paper; the heat radiation mechanism comprises a power supply, a fan, a paper plate and a paper plate groove; the paper plate, the fan and the power supply are connected by wires; the fan is fixedly connected with a rotating shaft; the rotating shaft is connected with a speed reduction gear set through an input shaft; the output shaft of the speed reduction gear set is connected with a threaded rod; the threaded rod is connected with a casing; and the casing is fixedly connected onto the piston. The capacitor is cooled by using the water pipe to be wound on the capacitor and water to flow in the water pipe, the fan is also rotated, and the cooling and heat radiation effects of the capacitor are further enhanced.

Description

technical field [0001] The invention relates to the technical field of electric power system capacitors, in particular to a cooling and cooling structure for capacitors. Background technique [0002] With the rapid development of the modern IT industry, power system automation has become the focus of people's attention, and the power sector has also made corresponding regulations on energy conservation. The power factor of general enterprises is usually between 0.65 and 0.8. If the enterprise wants to achieve Compensation must be made for power equipment to meet the country's electricity requirements. As a basic component of the circuit, the capacitor plays an important role in the circuit. Its quality directly affects the working state of the circuit. As a high-power component, the capacitor is easy to generate heat during long-term use. , it is easy to cause self-explosion, which will cause other electronic components around the capacitor to be damaged by it, thereby losi...

Problems solved by technology

This invention uses a heat conduction cylinder to absorb the heat of the capacitor element, and then transfers the heat to the shell of the capacitor through the heat conduction beam and the arc-shaped heat conduction sheet to improve the heat dissipation performance of the capacitor. This invention only absorbs the heat generated by the capacitor, Then transfer, but finally the shell temperature of the capacitor also rises, which may damage the shell of the capacitor. At the same time, there is an arc-shaped heat conduction sheet to absorb the heat of the shell and transfer it to the capacitor element.
