220KV Capacitor Voltage Transformer

1. General It is outdoor, single phase and oil capacitor voltage transformer, which is used for metering and relay protection of 220kv, 50HZ or 60HZ system. Its capacitor divider is also used as coupling capacitor in carrier wave coupling device in power line unit 2. Standards IEC Standard: IEC60044-5<Capacitor Voltage Transformer> National Standard: GB4703<Capacitor Voltage Transformer> GB311.1<Insulation Co-ordination for high voltage transimission and distribution equipment> 3. Service Condition Ambient Temperature:-40 +40°c Atitude: less than 2000m(more than 2000m. Technical conditions should be separately negotiated by both sides) Environment Pollution Level: II, III, IV 4. 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 electromagnetic 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 filing 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 compensate oil, get amount and compensate amount. The product checking and accepting needn't get oil, or can have harmful influence.
