15kv/27kv/38kv Recloser Wtith IEC61850 and DNP3.0 for Distribution and Substation

1.0 InstructionThe CHZ4(T)-12(15/27/38) KV/630A-1250A Providing the features of a traditional re-closer, plus the bene of up to date design optimized for automation, remote control and monitoring, now or in the future.by customer demand for improved return on capital investment in the distribution network to achieve optimum performance and reliability, making use of the latest available technology in insulation, vacuum interruption and microelectronics. Three phase pole-top automatic circuit re-closer are designed and produced by the three kind of international advanced technology, as epoxy solid encapsulated technology, permanent magnetic actuating device, and intelligence control technology and so on.The product is composite with solid dielectric insulted pole, permanent magnetic actuating device or motor actuating device, control unit, current transformer and vacuum interrupter and voltage sensor. Except the control unit is a single device, the others are combined together, compact frame, flexible design, easy to operate. The CHZ4(T)-12(15/27/38) KV/630A-1250A three phase pole-top automatic circuit re-closer is for 12kV(15KV/27KV/38KV),50/60Hz distribution system, has not only circuit breaker control and protection features, but also can automatically detect the lines running statement.Once the load side line or equipment occur a fault, meet or exceed current setting the minimum starting current, it will be good at a per-determined action sequence, to identify the fault is transient or permanent, and auto-complete one to three re-closing.2.0 Designing Standard2.0.1 ANSI-IEEE-Std-C37.60-2003,2.0.2 BS EN 60529-1992+A2:20132.0.3 IEEE Std.C37.60-2013, IEEE Std C57.12.29-20142.0.4 JB7570-1994, and DL/T813-20022.0.5 IEC56, IEC694, IEC62271-1113.Specification for Vacuum Circuit Breaker                         3.1 Ratings for ZW32-12(15) KV Vacuum Circuit BreakerNo.ItemUnitData for ZW32-12KVData for ZW32-15KV1Rated VoltageKV12152Rated insulation level(phase to ground, phase to phase)1 min Frequency withstand voltageDryKV4250Wet3445Lighting Impulse Withstand Voltage(Peak)KV751103Medium Interruption:Vacuum4Medium isolation:Solid polymer5Mechanism of operation (closing and shot):Magnetic6Assembly:Suitable weather for substation7Environmental operating temperature:FROM -40ºC-+50ºC8Position indicator: Green-closed; Open-red9Minimum distance of contouring of the insulationMM40060010Rated FrequencyHz50/6011Rated CurrentA630/800/125012Rated Min Start-up CurrentNumericalAadjustablePermissible deviation%±1013Rated Fault Interrupter CapacityKA/3s12.5/2014Rated Fault Symmetrical Making CurrentKA12.5/2015Rated Short-Time Withstand CurrentKA12.5/2016Rated Peak Withstand CurrentKA12.5/2017Interrupting Time(Max) (Cycle)sNo more than 418The conditions of different phase earthed fault short-circuit breaking currentKA17.319Rated Cable Charging Breaking currentA2520Rated Operating Sequence O-0.1s-CO-2s-CO-2s-CO-C21Rated Operation VoltageVAC/DC110/125/220/24022Rated Short-Circuit Current Breaking TimesTime 90%~100% Rated Short-Circuit Current volume1645%~55% Rated Short-Circuit Current volume4415%~20% Rated Short-Circuit Current volume5623Mechanical Life (Mechanical stability)Time/Unit Operation1500024Current TransformerPrimary Rated CurrentA600/1000Secondary Rated Current1 or 5Accuracy GradeCL0.2/5P20CapabilityVA1525Special Manual Closing Mechanism  optional26Earthing Solidly Earthed            3.2 Ratings for ZW32-27(38) KV Vacuum Circuit Breaker No.ItemUnitData for ZW32-27KVData for ZW32-38KV1Rated VoltageKV27382Rated insulation level (phase to ground, phase to phase)1 min Frequency withstand voltageDryKV6595Wet5080Lighting Impulse Withstand Voltage(Peak)KV145/1501853Medium Interruption:Vacuum4Medium isolation:Solid polymer5Mechanism of operation (closing and shot):Magnetic6Assembly:Suitable outdoor for substation or pole mounted7Environmental operating temperature:FROM -40ºC-+50ºC8Position indicator: Green-closed; Open-red9Minimum distance of contouring of the insulationMM68090010Rated FrequencyHz50/6011Rated CurrentA200A/400A/630A/1250A12Rated Min Start-up CurrentNumericalAAdjustablePermissible deviation%±1013Rated Fault Interrupting CapacityKA/3S12.5/2014Rated Symmetrical Making CurrentKA12.5/2015Rated Short-Time Withstand CurrentKA12.5/2016Rated Peak Withstand CurrentKA12.5/2017Interrupting time(Max)(Cycle)SNot more than 4 18The conditions of different phase earthed fault short-circuit breaking currentKA12.52019Rated Cable Charging Breaking currentA2520Rated Operating Sequence O-0.1s-CO-2s-CO-5s-CO-C21Rated Operation VoltageVAC/DC110/125/220/24022Rated Short-Circuit Current Breaking TimesTime  90%~100% Rated Short-Circuit Current volume 16 45%~55% Rated Short-Circuit Current volume 44 15%~20% Rated Short-Circuit Current volume 5623Mechanical Life (Mechanical stability)Time/unit Operation1000024Current TransformerPrimary Rated CurrentA600/1000  Secondary Rated Current 1 or 5  Accuracy GradeCL0.25/5P20  CapabilityVA1525Special
