The importance of Y capacitance in the action of an unconventional capacitance (1)

The capacitance between the fire line and the ground wire and between the zero line and the ground wire is generally referred to as the Y capacitor. The position of the two Y capacitor connections is critical. It is necessary to meet the relevant safety standards in order to prevent the leakage of electronic equipment or the electrification of the casing, which is easy to jeopardize the safety and life of the human body.

They all belong to the safety capacitance. The capacitance value can not be too large, and the withstand voltage must be high. In general, the machine working in the subtropics requires that the ground leakage current can not exceed 0.7mA, working in the temperate machine, and the leakage current of the ground must not exceed 0.35mA. Therefore, the total capacity of Y capacitors can not exceed 4700pF (472).
