Classification
Safety capacitors are divided into x-type and y-type. The AC power
input is divided into 3 terminals: live wire L/neutral wire
N/ground wire G, (L=Line, N=Neutral, G=Ground). Across between
"LN", that is, between "live wire-neutral wire" is the X capacitor;
between "LG/NG", that is, between "live wire-ground wire or neutral
wire-ground wire" is Y capacitance. Connecting a capacitor between
the live wire and the neutral wire is like "X", and connecting a
capacitor between the live wire and the ground wire is like a "Y",
these are not divided according to what material.
X capacitor
Since the position of the capacitor connection is also critical, it
also needs to comply with relevant safety standards. The X
capacitor is also one of the safety capacitors. 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 positions of these two Y capacitors are critical and
must comply with relevant safety standards to prevent leakage of
electronic equipment or electrification 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 capacity of Y
capacitors generally cannot exceed 4700PF (472).
