HDY系列电压继电器是静态型，不带方向性的、瞬动、交流电压继电器。
可用于发电机、变压器和输电线的继电保护装置中，作为过电压保护或低电压闭锁的动作元件。该继电器由集成电路构成执行回路，具有灵敏度高、动作速度快、功耗小、整定方便等特点，继电器的直流电源和出口继电器由信号指示灯监视，继电器由两转换接点输出，用户可根据具体情况直接控制被保护设备。继电器动作值由面板上的拨轮开关和编码开关进行整定。(适用于交流50/60Hz)
Being statictype instantaneous acting AC relays, HDY series of voltage relay can serve as acting
component in generators, transformers, and power transmission lines for protection against over voltageand fo r low voltage lockout. Composed of integrated circuits as its acting loop, this type of relay is characterized by high sensitivity, quick action, low power consumption, and easy setting etc. With LED signals monitoring the DC power supply of this delay and its trip relay, the users can directly control the equipment under protection.The operate values
of this delay can be set by wheel and code switches. (Are used in AC 50/60Hz)
