Can safety capacitors be replaced with the same voltage and capacity, but with different volume sizes
2021.09.15
Safety capacitors, as safety capacitors, refer to those used in situations where the failure of the capacitor will not cause electric shock or endanger personal safety.
Safety capacitors include X capacitors and Y capacitors. The x capacitor is a capacitor that spans between two lines (L-N) of a power line and is generally selected as a metal thin film capacitor; Y capacitors are capacitors that are connected in pairs between two power lines and ground (L-E, N-E). Based on the limitation of leakage current, the value of Y capacitance cannot be too large. Generally, X capacitance is of uF level, and Y capacitance is of nF level.
Why is there a difference in volume when the voltage resistance and capacity of safety capacitors are the same?
The voltage resistance and capacity of safety regulated capacitors are the same, but their volume sizes are different, and there may be differences in size. This may be due to different manufacturers of safety regulated capacitors and the same internal structure, which is affected by the process. If the difference is too large, it may be due to the production of customized safety capacitors according to customer requirements.
Can it be replaced?
Mainly based on the safety capacitor model, such as X1; X2； Y1； Y2.。 If consistent, it can be replaced. In addition, it is important to ensure that the voltage withstand and capacity parameters are consistent, or that the voltage withstand value is greater than the operating voltage value. The size does not affect it, and it can be replaced if it can be installed.
