Why do high voltage pulse capacitors use PC ceramics to produce?
Release date: 2017-09-15 14:56:07 Visits: 1925
First, the PC capacitor resistance voltage is extremely high.Pulse capacitor is composed of a number of high-frequency superposition of a limit peak, the actual equivalent of an AC operating voltage, such as 50KV pulse voltage, the actual equivalent of 50KV exchange. It is destined to pulse capacitor to have excellent AC characteristics to PC pulse capacitor 50KV2000PF, for example, this PC capacitor can reach more than 70KV AC voltage.
Second, the temperature change rate of the PC capacitor is very small. In the pulse of the process, the capacitor by repeated pulse, in a very short pulse in a sharp temperature rise, often a lot of ceramic capacitors because of this very short temperature rise and the PC capacitor is not. Because the PC capacitor is a capacitor suitable for high temperature and low temperature environment, the temperature change rate is only about 5% in the range of -55 ℃ or + 125 ℃.
Third, the PC capacitor is too large current capacity. Power is high. Pulse power of the power of the PC capacitor is completely affordable.
Of course, in addition to the three major advantages, the high-voltage pulse ceramic capacitors have the same magic weapon: the capacitor of the local discharge is very small.To measure the quality of a capacitor the simplest way is to see its partial discharge. The case of capacitors in the 20KV Work, the local discharge is about zero PC. This is the engineering and technical personnel favorite PC capacitor reasons.
