De veiligheidscondensator is onderverdeeld in x-type en y-type. De wisselstroomingang is onderverdeeld in 3 klemmen: Fire L/Zero N/Ground, (L=Lijn, N=Neutraal, G=Ground). Tussen "L-N", d.w.z. "Fire-Zero", bevindt zich de X-condensator; tussen "L-G/N-G", d.w.z. "Fire-Ground" of "Zero-Ground", bevindt zich de X-condensator. of "zero-ground" bevindt zich tussen de Y-condensator. Tussen de vuurdraad en de nullijn verbonden met een condensator als "X", en tussen de vuurdraad en de aardedraad verbonden met een condensator als een "Y", deze zijn niet volgens welk materiaal te verdelen.
Safety standard capacitor
X capacitor: Because the location of this capacitor is also critical, it also needs to comply with the relevant safety standards, and X capacitor is also one of the safety capacitors. According to the actual needs, the capacitance of X capacitor is allowed to be larger than the capacitance of Y capacitor, but at this time, a safety resistor must be connected in parallel to both ends of X capacitor, which is used to prevent the power cord from being unplugged, due to the charging and discharging process of the capacitor and the power cord plug is charged for a long time. Safety standards, when the machine is working in the power cord is unplugged, in two seconds, the power cord plug voltage charged at both ends (or potential to ground) must be less than 30% of the original rated working voltage.
Als een van de veiligheidscondensatoren, is X condensator ook verplicht om de certificering van de veiligheid testbureau te verkrijgen. X-condensator is over het algemeen gemarkeerd met een veiligheidscertificering en een weerstandsspanning van AC250V of AC275V, maar de werkelijke DC weerstandsspanning is tot 2000V of meer, dus gebruik geen gewone condensatoren met een nominale weerstandsspanning van AC250V of DC400V als vervanging.
Meestal gebruikt de X condensator het mylar filmtype condensator met een hoge rimpelstroom. Dit type condensator is groter, maar de ogenblikkelijke laad- en ontlaadstroom is ook groot en de inwendige weerstand is kleiner.

Y capacitors: The two Y capacitors are connected in critical positions and must comply with the relevant safety standards to prevent leakage from electronic devices or electrically charged cases, which can easily endanger personal safety and lives. They are safety capacitors, which require the capacitance value not to be large, and the withstand voltage must be high. Therefore, the total capacity of Y capacitor should not exceed 4700PF (472).
GJB151 stipulates that the capacity of Y capacitor should be no more than 0.1uF. In addition to conforming to the corresponding grid voltage withstand voltage, Y capacitors are required to have sufficient safety margin in electrical and mechanical performance to avoid The voltage withstand performance of Y capacitor is important to protect personal safety.ใ€€Y capacitors are mostly orange or blue in appearance, and are generally marked with safety certification marks (such as UL, CSA, etc.) and withstand voltage of AC250V or AC275V. However, the true DC withstand voltage is up to 5000V or more. It must be emphasized that Y capacitors should not be used in place of ordinary capacitors with nominal withstand voltage of AC250V or DC400V.
