GCS Low Voltage Withdrawable Switchgear
Overview
LV withdrawable switchgear is suitable for distribution systemof power plant, high building and some lines, such aspetroleum chemistry and industry, metallurgy, textile, etc. It isapplicable for distribution, motor centralized control, reactivepower compensation in power generation and power supplysystem of three phase AC 50/60Hz, rated voltage380V(400V,600V), rated current 4000A and below, whererequire high automation and interfaces with computers.
Operating Conditions
1.Ambient temperature:-5 ~+40 ,daily average +35 . Itshould reduce capacity according to real condition when outof stipulation;
2.Indoor, Altitude 2000m;
3.The change of ambient relative temperature will cause alittle moist by accident;
4.The slant between device installation position and verticalsection 5%;
5.Occasions without flammable and explosive matter, withoutcorrosive chemical and frequent severe vibration
Structure Feature
1.Main frame adopts 8MF open type steel which bended by 2.5mm cold rolled steel sheet. There are modulus with20mm,100mm, 9.2 mm installation hole located on threeside, high strength for modelling installation conveniently.
2.The drawer divided into 1/2 unit,1 unit, 2 unit, 3 unit, looprated current is 400A and below.
3.Flexible assembly, compact structure, strong versatility,perfect secure performance, convenient assembly.
4. Improve thermal capacity of patchboard, reduce additionaltemperature rise of plug in, cable terminal, isolating boarddue to temperature rise of transition element.
5.It can not influence others unit when any unit appears tofault between function unit and isolating unit, limit theemergency in a small scope.
6.Busbar horizontal is good for dynamic and thermal stableperformance.
7.The maximum 22 loops for MCC single panel, takeconsideration of requirement of auto motor door groupabout large unit capacity power plant, petroleum chemistrysystem line.
8.It finish connection of device and outer cable in cablecompartment, upper and down inlet and outlet is available.The zero sequence current transformer is installed in thecable isolating compartment.
9. It can limit short circuit current depend on limited reactor in the same power distribution system, to stabilize busbar voltage, reduce short circuit intensity requirement.
