KSQ331E1同步继电器精简说明

一、产品概述

KSQ331E1同步继电器（Megacon生产，ANSI 25类），用于电力系统两电源（发电机与电网、两台发电机）同步检测，监测电压、频率及相位，参数达标并稳定设定延时后，输出合闸允许信号，避免非同步并网损坏设备，适用于工业配电、发电机组并网场景。

二、核心参数

- 电源：辅助电压200/240V AC（50/60Hz，±10%波动），输入电压多规格可选（100-120V AC等）。

- 性能：频率范围45-65Hz，相位误差4-30°可调，电压误差±15%可调，动作延时0-500ms，触点容量AC 100VA（250V/2A）、DC 50W（100V/1A）。

- 物理：重量约470g，支持导轨/插座安装，适配工业控制箱。

三、工作原理

基于电磁感应与力矩平衡，采集两侧电源参数并与阈值对比，参数达标且稳定至设定延时后，触点（端子11-12）闭合。配备旋转LED指示灯，仅作同步检查，无合闸延时补偿功能，不可用于自动同步控制。

四、安装与调试要点

- 安装：环境洁净干燥、通风防干扰，多台安装预留≥5mm间隙，线圈与触点按规格接线，高低压线路分开布设。

- 调试：断电操作，先检查外观与绝缘电阻，设定参数后模拟电源测试功能，接入额定负载验证运行状态。

五、安全维护与故障排除

- 安全维护：操作必断电，做好静电防护，感性/直流负载需加保护元件；定期巡检、清洁及校准参数。

- 常见故障：电压误差灯常亮查电压与线路；参数正常触点不动作查延时、线圈电压及触点；过热异响查间距、负载及线圈。

Simplified Explanation of KSQ331E1 Synchronous Relay

1、 Product Overview

KSQ331E1 synchronous relay (produced by Megacon, ANSI Class 25) is used for synchronous detection of two power sources (generator and grid, two generators) in power systems, monitoring voltage, frequency, and phase. After the parameters meet the standard and the delay is stably set, it outputs a closing permission signal to avoid equipment damage caused by asynchronous grid connection. It is suitable for industrial distribution and generator grid connection scenarios.

2、 Core parameters

-Power supply: Auxiliary voltage 200/240V AC (50/60Hz, ± 10% fluctuation), input voltage available in multiple specifications (100-120V AC, etc.).

-Performance: Frequency range of 45-65Hz, adjustable phase error of 4-30 °, adjustable voltage error of ± 15%, action delay of 0-500ms, contact capacity of AC 100VA (250V/2A), DC 50W (100V/1A).

-Physics: weighs approximately 470g, supports rail/socket installation, and is compatible with industrial control boxes.

3、 Working principle

Based on electromagnetic induction and torque balance, collect power parameters on both sides and compare them with threshold values. After the parameters meet the standard and stabilize until the set delay, the contacts (terminals 11-12) close. Equipped with a rotating LED indicator light for synchronization check only, without closing delay compensation function, and cannot be used for automatic synchronization control.

4、 Key points for installation and debugging

-Installation: The environment is clean and dry, with ventilation and anti-interference. Multiple units should be installed with a reserved gap of ≥ 5mm. The coils and contacts should be wired according to specifications, and the high and low voltage lines should be arranged separately.

-Debugging: Power off operation, first check the appearance and insulation resistance, set parameters, simulate power testing function, and connect to rated load to verify the operating status.

5、 Safety maintenance and troubleshooting

-Safety maintenance: Power must be turned off during operation, static electricity protection should be done well, and protective components should be added for inductive/DC loads; Regularly inspect, clean, and calibrate parameters.

-Common faults: The voltage error light is always on. Check the voltage and circuit; If the parameters are normal and the contacts do not move, check the delay, coil voltage, and contacts; Check the spacing, load, and coil for overheating and abnormal noise.
