HDX系列相序保护继电器用于相序检测或断相保护中，当电路中相序与***相序相符时，继电器动作，
设备主控制回路接通。当电路中相序与***相序不符时或回路中任一相断线时继电器无法接通，从而保护了设备，避免事故的发生。
HDX series Phase sequence protection relay is used in phase-seque nce detection or open-phase protection. When the phase sequence in the circuit synchronizes with the specified phase sequence,the relay will be actuated and the main control loop of the equipment will be switched on. When the phasesequence in the circuit differs from the specified one or when any phase in the circuit is open, the relay will be released, thus protecting the equipment from accidental damage.
