KYN28A High Voltage Metal-clad Movable Switchgear
Product Summary
KYN28A high voltage indoor metal-clad movable switchgear is a completepower distribution device for 12kV,3 phase AC 50/60Hz,single bussectionalized system.It is mainly used for power transmission ofmiddle/small generators in power plants,power receiving.transmission forsubstations in power distribution and power system of factories,mines andenterprises,and starting of large high-voltage motor etc.,so as to control,protect and monitor the system.It complies with IEC 62271,IEC 60943,IEC
60068,IEC 600816,ANSI C37.85 and other relative standards.It hasfunctions of preventing to push or pull the breaker's handcart with load,breaker's mistakenly open or close,shut off the breaker when the groundingswitch is on the position of close,enter into a electriferous compartment,mistakenly close the interlock function of the grounding switch when it iselectriferous.It can be used with domestic VCA and VS1 vacuum circuitbreaker,it can be used with VD4 from ABB and EV12S from Schneider.
Environmental Conditions
● Ambient Temperature:No more than +40C and no less than -15C.Averagetemperature is no more than +35C within 24 hours.
● Altitude:No more than 1000m.
● Relative Humidity:the average daily value is no more than 95%,theaverage monthly value is no more than 90%.
● Earthquake Intensity:No more than 8 degrees.
● Vapor pressure:average daily value is no more than 2.2kPa,averagemonthly value is no more than 1.8kPa.
● Installation locations without fire,explosion danger,serious pollution,chemical corrosion and violent vibration.
Product Features
● The cabinets and partition boards adopting hot-dip Al-Zn alloy-coatedsteel sheet and frame adopting multiple bending technology make highoverall intensity and good earth continuity.
● Fully considering the operation characteristics of the neutral point of thepower system without grounding or through the arc suppression coil
● Grounding,increase the insulation clearance and enhance the insulationlevel,so as to ensure that the switchgear meets the high requirements for
● The insulation strength.
● Completely metal clad and absolutely compartments separation.
● The degrees of protection is IP4X,which effectively prevents theequipment from being invaded by sundries and insect pests.
● Simple and effective mechanical block for five-preventions,preventingfrom mis-operating.
● The movable handcart use sworm and worm wheel propelling mechanism.The same type of handcart can be interchanged completely,easy tooperate and maintain.
● It can be installed away from the wall,which is more convenient for doublesides maintenance.Or it can be installed against the wall,maintain in frontof the cabinet,with less space occupation.
● Min.width of panel is 550mm,which can increase the utilization ofdistribution room.
● The product runs safely and reliably through the harsh condensation,filthand internal arc tolerance test.
