1.产 品 资 料 介 绍：

KSQ331E1 同步继电器是一种用于发电机或电源系统的同步检测设备。它主要用于监测两路电源的相位、频率和电压差，确保在条件满足时才允许闭合断路器，从而避免并网或切换时设备受损。

主要用途

• 发电机并网或备用电源切换时的同步检查

• 控制面板内同步状态指示

• 作为闭合断路器的辅助信号输出

工作原理

• 继电器检测两路电源的电压、频率和相位

• 当误差在设定范围内且持续足够时间后，内部触点闭合

• 触点闭合用于控制断路器闭合或指示同步状态

• 如果不符合条件，继电器保持断开，防止非同步操作

特性

• 可适应不同系统电压（例如 200/240V、380/415V 等）

• 内部可调相位误差和延迟时间

• 结构紧凑，重量轻，适用于工业、船用或发电控制系统

• 用于手动或半自动同步辅助，不自动补偿断路器延迟

KSQ331E1同步继电器 英文介绍

KSQ331E1 synchronous relay is a synchronous detection device used for generators or power systems. It is mainly used to monitor the phase, frequency, and voltage difference of two power sources, ensuring that the circuit breaker is only allowed to close when conditions are met, thereby avoiding equipment damage during grid connection or switching.

main purpose

Synchronization check during generator grid connection or backup power switching

Synchronization status indication within the control panel

As an auxiliary signal output for closing circuit breakers

working principle

Relay detects the voltage, frequency, and phase of two power sources

When the error is within the set range and lasts for sufficient time, the internal contacts close

Contact closure is used to control circuit breaker closure or indicate synchronous status

If the conditions are not met, the relay remains disconnected to prevent asynchronous operation

feature

Can adapt to different system voltages (such as 200/240V, 380/415V, etc.)

Internally adjustable phase error and delay time

Compact structure, lightweight, suitable for industrial, marine or power generation control systems

Used for manual or semi-automatic synchronous assistance, without automatic compensation for circuit breaker delay
