ZW32-12FG/630A 10kV Floor-mounted High Voltage Vacuum Circuit Breaker Feeder Protection Manual/Electric Dual Operation
Short Description:
ZW32-12FG/630A (F=Feeder Protection, G=with Disconnector) is a dual-purpose (floor/pole-mounted) vacuum circuit breaker for 10kV (12kV rated insulation) outdoor distribution networks. It integrates vacuum interrupter, disconnector, high-precision zero-sequence/3-phase CT and intelligent feeder controller, featuring automatic fault isolation (single-phase earth/phase-to-phase short circuit), dual mechanical-electrical interlock, manual/electric dual operation. Floor-mounted fits pad-mounted transformer/outdoor switchgear; pole-mounted fits overhead lines. Compliant with GB 1984 & IEC 62271-100, maintenance-free, salt spray resistant, operating at -40℃~+40℃, ideal for urban/rural grid upgrading and distribution automation.
一、产品详细描述（Product Description）
10kV 配网中，分界开关（看门狗）是缩小停电范围、快速定位故障的关键。传统断路器无分界保护、隔离不可靠，落地安装适配性差，难以满足配网自动化需求。
ZW32-12FG/630A 落地式户外高压真空分界断路器，一体化设计解决上述痛点，核心优势：
- 分界保护 + 隔离双核心：智能控制器精准识别界内 / 界外故障，自动切除单相接地与相间短路，避免越级跳闸；隔离开关 + 双重互锁，杜绝带负荷拉隔离与反送电。
- 落地 / 柱上双安装：标准法兰底座，落地式直接固定于水泥基础 / 箱变内，柱上可配抱箍安装，满足不同场景快速部署。
- 手动 + 电动双操作：弹簧储能机构，无市电时手动手柄操作，有电源时电动 / 遥控分合闸，适配偏远无电与城区自动化两种工况。
- 高耐候 + 免维护：户外环氧固封 / 硅橡胶套管，真空灭弧无油无气，无爆炸污染；Ⅳ 级污秽等级，爬电距离充足，抗紫外线、抗盐雾，适应沿海、高原、重污区。
- 配网自动化兼容：支持 RS485/PRIME/PLC/5G，可接入 FTU/DTU，实现三遥（遥测、遥信、遥控），与配网主站无缝对接。
- 应用场景：10kV 户外落地式开关站、箱变进线 / 出线、工业园区环网柜、城乡配网架空线路分段、大用户分支分界开关、农网改造项目。
In 10kV distribution networks, feeder circuit breakers (fault locators) are critical to minimize outage areas and quickly identify faults. Traditional circuit breakers lack feeder protection, unreliable isolation and poor floor-mount adaptability, which cannot meet distribution automation requirements.
ZW32-12FG/630A Floor-mounted Outdoor High Voltage Vacuum Feeder Circuit Breaker, with integrated design, solves these pain points. Core advantages:
- Feeder Protection & Isolation Dual Core: Intelligent controller accurately distinguishes internal/external faults, automatically clears single-phase grounding and phase-to-phase short circuits to avoid over-level tripping; disconnector+dual interlock prevents load switching of isolator and reverse power transmission.
- Dual Installation (Floor/Pole): Standard flange base, floor-mounted directly on concrete foundation or in pad-mounted transformer; pole-mounted with hoop clamps, enabling rapid deployment in different scenarios.
- Manual & Electric Dual Operation: Spring-charged mechanism, manual lever operation without mains power, electric/remote switching with power supply, suitable for both remote off-grid and urban automation conditions.
- High Weather Resistance & Maintenance-free: Outdoor epoxy encapsulation/silicone rubber bushings, vacuum arc extinction without oil or gas, no explosion or pollution; Class Ⅳ pollution degree, sufficient creepage distance, UV resistance, salt spray resistance, adapting to coastal, plateau and heavy pollution areas.
- Distribution Automation Compatibility: Supports RS485/PRIME/PLC/5G, compatible with FTU/DTU, realizing telemetry, tele-signaling and remote control, seamlessly connecting to the distribution network master station.
- Application Scenarios: 10kV outdoor floor-mounted switch stations, pad-mounted transformer incoming/outgoing lines, industrial park ring main units, urban and rural distribution overhead line sectioning, large-user branch feeder breakers, rural power grid renovation projects.
