35KV Capacitor Voltage Transformer Single Phase Outdoor Type Oil-immersed Type
1. General It is outdoor, single phase and oil capacitor voltage transformer,which is used for metering and relay protection of 35kv, 50HZ or 60HZ system. Its capacitor divider is also as coupling capacitor in carrier wave coupling device in power line unit2. StandardsIEC Standard:IEC60044-5<Capacitor Voltage Transformer>National Standard:GB4703<Capacitor Voltage Transformer>GB311.1<Insulation Co-ordination for High Voltage Transmission and Distribution Equipment>3. Service ConditionAmbient Temperature:-40~+40°CAltitude:less than 2000m (more than 2000m, technical conditions should be separately negotiated by both sides)Environment Pollution Level: II, III, IV4. Structure Feature
It consists of capacitor voltage divider and electromagnetic unitThe capacitor divider is making up of one or several coupling capacitors to seriesH.V. terminal is at top of capacitor divider. Medium and low voltage terminal is in electromagnetic unit for leading from magnetic on lowest H.V. capacitor chassisNeutral transformer, compensation reactor and damper are filled in the tank, it makes up electormagnetic unit. Transformer oil is filled in the tank and sealed. Volume of oil and internal pressure are adjusted by air at top of tank. Neutral transformer primary side coil can regular coil and voltage error. Compensation reactor regular coil can regular error of phase, secondary winding come out from wiring terminal box of tank frontTHe product is filling oil and sealing, it needn't filter oil and change oil for keeping electric function. Please note mustn't destroy sealing of capacitor divider. If electromagnetic unit have to get oil, Please note must compensation oil, get amount and compensation amount. THe product checking and accepting needn't get oil, or can have harmful influence.35KV Outdoor Oil-immersed Type Capacitor Voltage Transformer
