Can the high-voltage ceramic capacitor be set to the nominal voltage for long-term operation?
The so-called nominal voltage refers to the voltage marked on the capacitor, also known as the rated voltage. Some users will ask: Now that the marked voltage is 50KV, can I work for a long time at a voltage of 50KV? Of course! Because of us The 50KVDC capacitor has a withstand voltage far exceeding 80KVDC. However, please note:
As we all know, long-term work, if it is full load, this will cause damage to the life of the capacitor. Because the safety margin of the voltage is not enough! If the life of the capacitor is long enough, the margin should be left! For example, 50KVDC Capacitors can be set at around 30KV for long-term use. I have seen customers working as 20KV capacitors for a long time. They have worked in harsh environments for many years without exception, but there is enough margin!
For example, in the standard of the power system, the 10KV AC power grid requires the withstand voltage of the capacitor to reach or far exceed 42KVAC. This is the reason. Because safety is no small matter, the equipment is not allowed to cause problems. Once a problem occurs, the power grid will lose a lot. !
Therefore, the correct usage is: it is recommended to use within the marked voltage, and do not exceed the rated voltage, which will affect the life of the equipment!
