Capacitors for welding machine make an important influence on welding machine performance.They are very compact and have a high power/volume ratio, thus ensuring optimal performance.They are made of high quality metallized polypropylene film.
The ac voltage capacitor is a key power device in the high-frequency induction heating device. It cooperates with other components in the circuit to generate a resonant current to drive the heating device to heat up. Therefore, during the working process, the frequency is very high, and the heat generation is very large. The quality and working life of the resonant capacitor directly determine the reliability and service life of the induction heating equipment. Due to the large current and high frequency during the operation of the resonant capacitor, the heat generation is very surprising. If measures are not taken in time to take away the heat, once the heat accumulation is serious during the working process, the temperature rise of the capacitor is too high, which will seriously reduce its service life. Thus here is the water cooled resonant capacitor.
The cold water enters the circulating water tank from the cold water inlet of the water cooled resonant capacitor , and then flows out from the hot water outlet. The cold water exchanges heat with the electrode copper plate during the flow of the circulating water tank, and takes away a large amount of heat, which can greatly reduce the heat accumulation during the working process of the resonant capacitor, improve the reliability and service life of the resonant capacitor.
Capacitor for welding machine in rc integrated circuit is widely used in IGBT Snubber circuit; IGBT Snubber equipment, power electronic equipment UPS, inverter, induction heater, welding machine for protect and absorb peak current and peak voltage.Packing with plastic bag and foam box can be transported to prevent possible collisions.
