GT300系列電力電容器保護(hù)器可與切換電容器接觸器（晶閘管、復(fù)合開關(guān)、無功補(bǔ)償控制器、電抗器、熔斷器）等組成電力電容器控制系統(tǒng)。主要作為電力電容器及補(bǔ)償電路中可能出現(xiàn)的過流、短路、缺相、過壓等故障進(jìn)行保護(hù)；保護(hù)器作為電力電容器的過流、缺相保護(hù)的新型產(chǎn)品。
GT300 series power capacitor protector can be composed of switching capacitor contactor (thyristor, compound switch, reactive power compensation controller, reactor, fuse), etc. the control system of power capacitor. Mainly as the power capacitor and compensation circuit may appear over-current, short-circuit, lack of phase, over-voltage and other faults protection; protector as a power capacitor over-current, phase protection of new products.
