introduction：Residual current relay Residual current relay detects residual current，The residual current value is compared with the reference value，When the residual current value exceeds the reference value，An electrical appliance that emits a mechanical on/off signal to cause a mechanical switch appliance to trip or an audible and visual alarm device to issue an alarm。Residual current relays are often combined with AC contactors or low-voltage circuit breakers to form residual current protectors，It is used as the total protection switch or branch protection switch of rural low-voltage power grid。 Fengye residual current relay definition： 1、Rated operating voltage：Refers to the voltage required by the coil when the relay is working normally，That is, the control voltage of the control circuit。It depends on the type of relay，It can be AC voltage，It can also be DC voltage。

introduction：Bearing classification： LYCDeep groove ball bearing，LYCAligning ball bearings，LYCThrust ball bearing，LYCAngular contact ball bearing，LYCSelf-aligning roller bearings Deep groove ball bearing： Deep groove ball bearing imported bearings are mainly used to withstand pure radial load，It can also withstand both radial and axial loads。When it is subjected to pure radial load only，The contact Angle is zero。When the deep groove ball bearing has a large radial clearance，Angular contact bearing performance，Can withstand large axial loads。The friction coefficient of deep groove ball bearing is very small，The limit speed is also very high，Especially under high speed operating conditions with large axial loads，Deep groove ball bearings have more advantages than thrust ball bearings。Deep groove ball bearing is the most representative rolling bearing，versatile。Suitable for high speed or even very high speed operation，And very durable.，No frequent maintenance required。The friction coefficient of this kind of bearing
