Electric Control System Dc Relay , 24 Volt Phase Balance Relay DVRD-12
The voltage protection relay is a multi-function three-phase three-wire power system or three-phase power equipment monitoring and protection equipment. Sets three-phase voltage display, over-voltage protection, under-voltage protection, phase loss protection (phase protection), three-phase voltage imbalance protection, phase sequence protection (wrong phase protection) in one. It can be used to monitor important parameters (voltage, phase sequence, phase loss, and phase balance) in three-phase power supply system. It can send alarm signals in time to abnormal conditions that may endanger the safe and reliable operation of power systems and equipment. The system can be properly handled before the machine equipment is more damaged, so that the machine equipment and system can obtain the maximum degree of protection, improve the effectiveness of the machine, equipment and system, and reduce maintenance costs due to three-phase system failures. Maintenance time.
Voltage protection relay (also known as three-phase power monitor, phase sequence protector, over-voltage protection, etc.) is mainly used for AC 50/60Hz, rated voltage below 660V, industrial three-phase 100V, 220V, 380V (400V), 440V (460V), 660V and other voltage level fault detection, provide relay protection for three-phase input power supply voltage is too high, voltage is too low, phase failure, wrong phase (reverse phase sequence), three-phase voltage imbalance, etc. It can be widely used in power distribution cabinets, distribution boxes, electronic control boxes, power electronic devices, telecom communication room power supplies, etc. It is an indispensable protection product that maintains normal working voltage of industrial equipment during operation.
