Detailed Description

IP56 SF6 Gas Insulated Switchgear MV GIS 630A 1250A 2000A 2500A General The gas insulated switchgear designed for installation in transformer substation, industrial plants, and infrastructure & complies the most stringent requirement of Safety in operation Staff safety Operation reliability Smaller footprints Reduced maintenance work This switchgear conforms to IEC 62271-200 and all primary components employed therein are in accordance with the relevant standards. It is designed to accommodate high performance vacuum circuitbreaker (VCB) which has been designed and tested in accordance with IEC62271-100. The switchgear panels are suitable for the assembly of single &double busbar systems for indoor installation. Features: 1. Reliable Each compartment is monitored individually &has its own pressure relief device. Use of Vacuum circuit breakers with high number ofmechanical & electrical operations Robust interlocking system 2. Safety The primary side components are hermetically enclosed, gas filled compartment and thus insensitiveto atmosphere, dirt &dust. Current transformer are mounted outside the gas compartment & mounted on earthed LV compartment 3. Space saving Smaller foot prints. All operations on the switchgear front 4. Economically efficient Reduced space & surface area requirement. Long service life Maintenance free Gas compartment Technical Data - - - - S/N | Item | Unit | Data | 1 | Rated voltage | kV | 12 | 2 | Rated current | A | 630 1250 2000 2500 | 3 | Rated frequency | Hz | 50/60 | 4 | Rated power frequenecy withstand voltage (1 min) | | | 5 | Phase to phase, phase to earth | kV | 45 | 6 | Between clearance | kV | 48 | 7 | Rated ligtning impulse withstand voltage | | | 8 | Phase to phase, phase to earth | kV | 75 | 9 | Between clearance | kV | 85 | 10 | Power frequency withstand voltage of auxiliary control circuit (1 min) | V | 2000 | 11 | Rated short-cricuit breaking current (rms) | kA | 20 25 31.5 | 12 | Rated short-circuti making current | kA | 63 80 100 | 13 | Rated short time withstand current | kA/s | 25/4 31.5/4 40/4 | 14 | Rated peak withstand current | kA | 63 80 100 | 15 | Degree of protection | | Gas-filled compartment : IP67 LV compartment: IP4X | 16 | Every phase amin return circuit resistance | u | <250 | 17 | Rated SF6 gas pressure (20C) | Mpa | 0.045 | 18 | Min SF6 gas pressure (20C) | Mpa | 0.03 | 19 | Annual SF6 gas loss rate | % | <1 | 20 | Rated voltage of auxiliary control circuit | V | DC 110/220 AC 220 | 21 | Dimensions (WxDxH) | mm | 500x1000x1850 | - - - -
