SELCO负载共享器T4800系列产品介绍
The T4800 Load Sharer for Conventional Governors
The Load Sharer T4800 is designed to control a generator operating in parallel with the grid, or a generator operating in parallel with other generators (which are also controlled by T4800 units).
The T4800 will continuously measure and compare the active current on the generator to an external DC reference signal connected to the “parallel lines” input. The T4800 will increase or decrease the speed of the generator (through the governor) if it finds the active current level to be either too low or two high. Two built-in relays provide the increase and decrease pulses for a conventional governor. The strength (width) of the pulses is proportional to the frequency/phase deviation. The E7800 Motorised Potentiometer can be used to adapt the contact pulses to a signal suitable for the speed trim input of an electronic speed controller.
Features:
Active load sharing
System frequency control
Relay based speed control
Reverse power protection
Soft unload with breaker trip
50 hour burn-in before test
Certified for marine use
适用于传统调速器的T4800负载共享器
负载共享器T4800旨在控制与电网并联运行的发电机，或与其他发电机（也由 T4800 装置控制）并联运行的发电机。
T4800将连续测量发电机上的有功电流并将其与连接到“平行线”输入的外部直流参考信号进行比较。如果T4800发现有功电流水平太低或高两倍，它将增加或降低发电机的速度（通过调速器）。 两个内置继电器为传统调速器提供增加和减少脉冲。脉冲的强度（宽度）与频率/相位偏差成正比。E7800 电动电位计可用于将接触脉冲调整为适合电子速度控制器的速度微调输入的信号。
特征：
主动负载共享
系统频率控制
基于继电器的速度控制
逆功率保护
带断路器跳闸的软卸载
测试前50小时老化
