ZC-23H型冲击继电器
ZC-23H型冲击继电器产品介绍（中文）
ZC-23H型冲击继电器是一种专为直流及三相全波整流操作设计的信号集中控制元件，广泛应用于电力系统继电保护及自动化控制回路中。该继电器采用干簧密封触点技术，内部集成电容、二极管及滤波元件，确保动作可靠性和抗干扰性能。其核心工作原理是通过微分脉冲变流器（BL）将直流信号回路中的矩形电流脉冲转换为尖顶脉冲，触发灵敏元件（GHJ）启动出口中间继电器（ZJ），从而驱动电铃或电笛发出音响信号。继电器具备自动复归功能，当信号电流稳定后，执行元件自动复位，仅通过触点自保持维持输出状态。技术参数方面，支持额定电压DC220V/110V/48V/24V，最小冲击动作电流不大于0.16A（ZC-23H型），最大稳定电流3.2A，功率消耗低于7W（BL绕组）和10W（ZJ动作时）。产品采用JK-2型壳体，结构紧凑，适用于高密度安装场景，并可通过两台继电器反串接线实现冲击自动复归功能。2821
ZC-23H Impact Relay Product Introduction (English)
The ZC-23H Impact Relay is a centralized signal control component designed for DC and three-phase full-wave rectifier operations, widely used in power system protection and automation control circuits. It features sealed reed contacts with integrated capacitors, diodes, and filters to ensure reliable operation and noise immunity. The relay operates by converting rectangular current pulses in DC signal circuits into sharp peaks via a differential pulse transformer (BL), which activates the sensitive element (GHJ) to trigger the output intermediate relay (ZJ), thereby driving audible alarms like bells or buzzers. It supports auto-reset functionality, where the actuator resets upon signal stabilization while maintaining output through contact self-locking. Key specifications include rated voltages of DC220V/110V/48V/24V, a minimum impact action current of ≤0.16A (ZC-23H model), and a maximum steady-state current of 3.2A, with power consumption below 7W (BL winding) and 10W (ZJ activated). The compact JK-2 housing design suits high-density installations, and dual-relay reverse-series wiring enables automatic impact reset capabilities. 2821
