Voltage relay
classification
From the form, can be divided into: electromagnetic voltage relay and static voltage relay ( integrated circuit voltage relay )
From the structural type, can be divided into: convex type fixing structure, a plug-in type structure, embedded plug structure, guide rail type structure
From the voltage action type, can be divided into: over voltage relay and a low voltage ( under-voltage relay )
From the use, can be divided into: has the auxiliary source and without auxiliary source voltage relay in addition, common and DC voltage relay, three-phase voltage relay, the negative sequence voltage relay, with a time delay function of the voltage relay.
