  Customized products can consult online customer service! PRODUCT DETAILSKYN28A-24 (z) series armored removable AC metal switchgearDescription:        KYN28A-24 (z) series armored removable AC metal switchgear is a power distribution equipment for 20kV three-phase AC 50 (60) Hz single bus and single bus sectional system.        It is mainly used in power plants, small and medium-sized generator power transmission, industrial and mining enterprises power distribution and secondary substation of power systems for power receiving, power transmission and large high-voltage motor starting, etc., for control protection and monitoring. It can be equipped with 6-point or 9-point on-line temperature measurement technology, which can realize remote control of the electric operation of grounding switch, electric swing in and out of circuit breaker handcart and internal fault arc protection of switch cabinet, and realize intelligent control of switch cabinet.       The switch equipment has the "five prevention" interlocking function of preventing pushing and pulling the circuit breaker handcart with load, closing the circuit breaker by mistake, closing the circuit breaker when the grounding switch is in the closed position, entering the live compartment by mistake, and closing the grounding switch by mistake when the grounding switch is live. It can be used with VS1-24 vacuum circuit breaker developed by our company, which is a kind of superior power distribution device.        This product conforms to GB3906 "3-35kv AC metal enclosed switchgear" and IEC62271-200 "rated voltage above 1kV and below 52kv AC metal enclosed switchgear and control equipment" Product FeaturesVD4 vacuum circuit breaker from ABB or domestic VS1 vacuum circuit breaker may be chosen.The cubicle with high precision is assembled with imported steel plates coated with zinc & aluminum, which will not get rusty.Metal-clad completely, each function unit thoroughly separated.Even if the cubicle door is closed, the built-in withdrawable unit driven by a screw can be moved.A simple and effective fail-safe interlock will prevent error operation.Effective protection measures will ensure safety and prevent foreign materials and pests from entering.The cable terminal compartment is large enough to connect lots of cables.Both operation and monitoring are easy.OFast grounding switches for earthing and short-circuit.Through the plateau type, seismic, internal combustion arc test, meet the demand of a broader market.  The technical parameters of the form are for reference only.Customized products can consult online customer service!DescriptionUnitSpecificationsRated voltagekV24Rated power frequency withstand voltage(1 min)kV(50)65Rated lightning impulse withstand voltage(peak)kV125Rated frequencyHz50(60)Rated currentA630 1250 1600 2000 2500 3150Ratedxijrrent of branch busA630 1250 1600 2000 2500Rated short time withstand currentkA16202531.5Rated peak withstand currentkA40506380Rated short-circuit continuous times4Degree of protection Shell: IP4X, IP2X when CPT and CB door are openWeightkg800,1000(rated current N1600A)THE USE OF CONDITIONS Ambient air temperature: Maximum air temperature: +40ºCMinimum air temperature:-15ºC (Under a special process, up to-45 ºC)Altitude: 2500m(Under a special process, up to 4000m)Humidity: Daily average value of relative humidity:
