Y capacitors are used to reduce radio frequency interference by providing a low impedance path to earth for high frequency a.c. They are also used for bridging DOUBLE or REINFORCED INSULATION as part of the interference suppression regime. There are four types: Y1, Y2, Y3 and Y4. Y1 capacitors are designed for use with three phase mains and have a WORKING VOLTAGE of up to 500 V a.c. and a withstand voltage of 4 000 V a.c. Y2 capacitors are designed for use with single phase mains and have a WORKING VOLTAGE up to 300 V a.c. and a withstand voltage of 1 500 V a.c. Y3 capacitors are similar to Y2 capacitors but have a WORKING VOLTAGE up to 250 V a.c. Y4 capacitors are designed for use with low voltage mainsand have a WORKING VOLTAGE up to 150 V a.c. and a withstand voltage of 1 000 V a.c.

These capacitors are safety critical since they provide a leakage path to earth or across a barrier. So they must be certified and monitored by a recognised test house to IEC 60384-14, which serves to control their manufacture.

Y 电容器用于通过为高频交流提供低阻抗接地路径来减少射频干扰。它们还用于跨接双重绝缘或加强绝缘,作为干扰抑制机制的一部分。有四种类型:Y1、Y2、Y3 和 Y4。 Y1 电容器被设计用于与三相电源一起使用,工作电压高达 交流500V,耐压为交流 4 000 V。Y2 电容器被设计用于与单相电源一起使用,工作电压高达交流300V和耐压1500V。Y3 电容类似于 Y2 电容器,但是工作电压高达交流250V。 Y4 电容器设计用于低压电源,其工作电压高达交流150 V 和耐压交流1 000 V a.c。

这些电容器对安全至关重要,因为它们提供了接地或跨越屏障的泄漏路径。因此,它们必须由公认的测试机构根据 IEC 60384-14 / GB/T 6346.14-2015进行认证和监控,以控制其制造。
