*FAQ:
How many types of safety capacitors are there?
Safety capacitors are divided into x-type and y-type.
X capacitor: Since the connection position of this capacitor is critical, it also needs to comply with relevant safety standards. According to actual needs, the capacitance value of the X capacitor is allowed to be larger than that of the Y capacitor, but at this time, a safety resistor must be connected in parallel at both ends of the X capacitor to prevent the capacitor from being damaged due to the charging and discharging process when the power cord is unplugged and inserted. The power cord plug may be charged for a long time. The safety standard stipulates that when the power cord of the machine at work is unplugged, within two seconds, the live voltage (or ground potential) at both ends of the power cord plug must be less than 30% of the original rated working voltage.
Y capacitor: The connection position of Y capacitors is also critical, and must comply with relevant safety standards to prevent leakage of electronic equipment or charging of the chassis, which may endanger personal safety and life. They are all safety capacitors, so the capacitance value should not be too large, and the withstand voltage must be high. Under normal circumstances, the machine working in the subtropical zone requires that the leakage current to the ground should not exceed 0.7mA; the machine working in the temperate zone requires that the leakage current to the ground should not exceed 0.35mA. Therefore, the total capacitance of Y capacitors generally cannot exceed 4700PF (472).
