대사 & 호환성

국내 상당: VS1-12/630-25 (trolley-type, 150 mm phase spacing). Verify operating mechanism, secondary connector and trolley dimensions.
Schneider upgraded variant: New-generation EvoPacT HVX-D digital version, equipped with condition-monitoring function.

유지 & Inspection Checklist

Contact-resistance test: ≤80 μΩ for Type E-630A. Exceedance requires inspection of contact fingers, tulip contacts and main-circuit bolt torque.
Mechanical-characteristic test: opening/closing time, contact bounce, stroke and over-travel.
Power-frequency withstand-voltage test for vacuum interrupter.
Verify trolley interlock (insert/extract) and integrity of secondary connector.

비교: HVX12-25-06E150 vs VS1-12/630-25 (Trolley-type, 150 mm phase spacing)

목	Schneider HVX12‑25‑06E150	Domestic VS1‑12/630‑25 (Trolley‑150 mm)
Cabinet compatibility	KYN28‑12, 150 mm phase spacing, mechanically interchangeable	KYN28‑12, 150 mm phase spacing, physically interchangeable
Interrupter	Schneider VG embedded pole, APG epoxy resin, integrated pole module	Separate vacuum bottles; large quality variance among manufacturers
Performance class	M2 ≥20 000 operations; E2 electrical endurance; C2 capacitor‑switching rating	M2 for premium brands; M1 only for low‑end makers; C2 rating not always available
Main‑circuit resistance	≤80 μΩ	≤100 μΩ; wide scatter across vendors
작동 메커니즘	Modular spring mechanism; 코일 & motor field‑replaceable, 쉬운 분해	Monolithic mechanism; higher repair difficulty
Secondary interface	Standard aviation connector; terminal‑block option available	Mostly aviation connector; terminal‑block version custom‑built
Interlock features	Full portfolio: Y1 closing block, 저전압 릴리스, key‑locks, motorized trolley	Basic interlocks included; special functions require retro‑fitting
유지	모듈형 디자인; defective components replaceable on‑site, no full‑unit factory return	Mostly complete‑unit repair required
비용	Premium imported brand, 더 높은 가격	비용 효율적; 30‑60 % lower price
Use cases	Critical substations, petro‑chemical, data‑centres, high‑reliability installations	General‑purpose industrial plants, routine distribution retrofits

⚠️Replacement Notes (HVX ↔ VS1)

Primary-circuit phase-to-phase distance 150 mm must match exactly, otherwise contact fingers cannot mate properly.
Pin-out definition of secondary aviation connectors differ: Direct plug-in is invalid; secondary wiring modification is mandatory.
Coil and charging-motor operating voltages shall remain identical.
Trolley chassis dimensions are broadly compatible; dimensional tolerances of some domestic cabinets may require on-site adjustment.

III. Hand-over & Preventive-Test Checklist

Main-circuit resistance test: ≤80 μΩ. Investigate tulip-contact condition and bolt torque if exceeded.
Mechanical-characteristic measurement: opening 30-60 ms; closing 40-70 ms; check bounce, 뇌졸중, over-travel.
Vacuum-interrupter power-frequency withstand: 42 kV / 1 min; lightning impulse 75 kV.
Measure coil & motor resistance; verify rated operating voltage.
Interlock validation: test-position / service-position interlock, Y1 closing block, K0 anti-pumping.
Operate trolley in/out; inspect secondary-connector mating and extraction.
