SELCO負(fù)載共享器T4800系列產(chǎn)品介紹
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
適用于傳統(tǒng)調(diào)速器的T4800負(fù)載共享器
負(fù)載共享器T4800旨在控制與電網(wǎng)并聯(lián)運(yùn)行的發(fā)電機(jī)，或與其他發(fā)電機(jī)（也由 T4800 裝置控制）并聯(lián)運(yùn)行的發(fā)電機(jī)。
T4800將連續(xù)測(cè)量發(fā)電機(jī)上的有功電流并將其與連接到“平行線”輸入的外部直流參考信號(hào)進(jìn)行比較。如果T4800發(fā)現(xiàn)有功電流水平太低或高兩倍，它將增加或降低發(fā)電機(jī)的速度（通過(guò)調(diào)速器）。 兩個(gè)內(nèi)置繼電器為傳統(tǒng)調(diào)速器提供增加和減少脈沖。脈沖的強(qiáng)度（寬度）與頻率/相位偏差成正比。E7800 電動(dòng)電位計(jì)可用于將接觸脈沖調(diào)整為適合電子速度控制器的速度微調(diào)輸入的信號(hào)。
