In case of no excitation in transformer (i.e. no winding is charged), the switch can be operated manually or electrically to change the tapping position and further to change the transformation ratio, and by this means, secondary voltage can be adjusted or stabilized.Specific introduction:This series of switches is composed of the main body of the switch and the operation turning organ. They are applicable to the oil-immersed transformers with the frequency of 50Hz, 60Hz. They ca be fixed on the body of the transformer or on the box-cover, and be tapped, regulated and changed under on excitation condition.1.This kind of electric off circuit tap changer applies to the single-phase, three-phase, combination oil-immersed transformer of electrical power .2.The frequency of 50HZ,60HZ,rated voltage of 10KV,35KV,rated current of 30A~250A;the voltage-regulating places are: central part, neutralpoint, can be directly fixed on the box-cover of the transformer3.under the non-excitation condition regulating and changing.4.power deviceChinese manufacturer off circuit tap changerWST series off-circuit off load tap changer for transformerThis kind of switch applies to the single-phase, three phase, combination oil-immersed transformer electrical power with frequency of 50Hz,60Hz, rated voltage of 10KV,35KV, rated current of 30A~500A; the voltage-regulating mode are central part, terminal point and neutral point, which can be directly fixed on the tank cover of the transformer and exchanged under the off-circuit condition.Non-excitation strip Tap Changer for voltage regulator :This kind of switch applies to the single-phase, three phase, combination oil-immersed transformer electrical power with frequency of 50HZ,60HZ,rated voltage of 10KV,35KV,rated current of 30A~500A;the voltage-regulating mode are: central part, terminal point neutral point, which can be directly fixed on the tank cover of the transformer, exchange under the off-circuit condition.Technical data:SpecificationsWST 30WST 63WST 125WST 250WST 400WST 500Phase number three-phasesConnection mode(2) (3) (1)Central point(2)Neutral Point(3)Terminal Point(1)Rated through current(A)30631252504005000.71.62.53.7545Short-circuit capacityHeat stableness current(KA/2s)1.846.259.3751012.5Dynamic stableness current(KA) Rated frequency50~60(KV)Rated Voltage10KV20KV35KVInsulation level(KV)Power-frequency withstand Voltage(50Hz/1min)42KV55KV95KVImpulse(1.2/50μs)75KV125KV250KVSealing Performance(KPa/24h)60Machine life(Thousands of times)2Our other product series:WST series off-circuit off load tap changer for transformerThis kind of switch applies to the single-phase, three phase, combination oil-immersed transformer electrical power with frequency of 50Hz,60Hz, rated voltage of 10KV,35KV, rated current of 30A~500A; the voltage-regulating mode are central part, terminal point and neutral point, which can be directly fixed on the tank cover of the transformer and exchanged under the off-circuit condition.Off-circuit Single Phase Linear Tap Changer-Used in mineral oil or silicon oil -Used in mineral oil or silicon oil-Rated voltage 10KV-35KV -Rated voltage 10KV-24KV-Rated current from 63A-250A -Rated current from 30A-63A-Tapping position:3-7 -Tapping position:3-7-Regulation 2.5% per position -Regulation 2.5% per positionOff-circuit Three Phase Linear Tap Changer-Used in mineral oil or silicon oil -Used in mineral oil or silicon oil-Rated voltage 10KV-35KV -Rated voltage 10KV-35KV-Rated current from 63A-300A -Rated current from 63A-250A-Tapping position:3-9 -Tapping position:3-7-Regulation 2.5% per position -Regulation 2.5% per positionOff-circuit Combination Linear Type (ZH2)Three Phase Linear Tap Changer-Used in mineral oil or silicon oil-Rated voltage 10KV-35KV-Rated current from 63A-250A-Tapping position:3-5-Regulation 2.5% per positionOff-circuit Combination Linear Type (ZH3)Three Phase Linear Tap Changer-Used in mineral oil or silicon oil-Rated voltage 20KV-Rated current from 63A-250A-Tapping position:3-5-Regulation 2.5% per positionFAQ1.
