中/高压电容器

High-voltage Power Capacitor Application : They are widely used in power network for compensation the reactive power, improving the power factor and reducing theline loss.They are connected with filter reactor, resistor together to form a filter device which can filter the harmonics in power system and improve the power quality. Reference Standard : GB/T 11024.1- 2001 IEC 60871-1:1997 Standard : (Shunt Capacitor for AC Power Systems Having a Rated Voltage above 1kV Part I : General Performance Testing and Rating-Safety Requirment Guide for Installation and Operation) Technical Parameter : 1. Rated capacity:100kVAr 667kVar 2. Rated voltage: 1 35 kV 3. Rated current: 30 150 A 4. Solid dielectric: Polypropylene Film 5. Impregnation medium:(M/DBT) \ PXE ( C101 Oil ) Non-PCB 6. Discharge Resistor: Build-in high voltage glass glazed resistor 7. Capacity tolerance: -5% 10% (Shunt Capacitor) 8. Loss of Tangent:≤0.0003 or ≥0.0005 (with build-in discharge resistor and internal fuse) 9. Single Phase or Three Phase 10. Insulation Level (BIL LEVEL): 75kV 95kV 125kV Construction : These capacitors are used All film dielectric, updated new insulation oil (M/DBT or C101) and foil folded construction. It greatly ehancesthe withstand voltage strength, improves the partial discharge performance, reduces the reactive losses.Build-in discharge resistor can lower the residual voltage from√2Un to 75kV below within 5 mins after diconnected from the power. Using Condition : 1. Temperature range: -40oC 55oC 2. Mounting site: Outdoor or Indoor Type 3. Altitude: ≤1000 m 4. Other condition: The mounting place shall be free from all harmful gas or steam,electrically, explosive dust and strong mechanical shock. Enclosure of Capacitor : 1. Enclosure material: Stainless steel or steel plate 2. Surface treatment: Coated two layers of anti-rust paint( light gray colour)after under sand blasting processing Terminals: Bushing: Brown or white color andextra strongpocerlain. Single phase capacitors have one or two bushings; Three-phase capacitors have three bushings. Mounting Way : Upright or lay-side Ordering Instruction : If customers requires special specification which is different from our normal one, welcome to negotiate with us and make a remark in the contract or the technical agreement for certain mode, quantity and delivery.
