35kV Outdoor Pole-mounted Double Isolation Dual Power Manual Vacuum Circuit Breaker ZW32-40.5GG/630
deskribapen laburra:
ZW32-40.5GG/630 is an integrated vacuum circuit breaker with double isolation and dual power manual transfer, designed for 35kV (40.5kV insulation level) outdoor dual-power distribution networks. It integrates vacuum interrupter, double-side independent disconnectors and mechanical operating mechanism, featuring dual mechanical-electrical interlock to completely eliminate reverse power transmission and misoperation risks of switching disconnectors under load. It supports manual switching between main and backup power, short-circuit/overload/earth fault protection, no external power supply required, ideal for remote off-grid, high-safety outdoor pole-mounted applications. Compliant with GB 1984 and IEC 62271-100 international standards, operating temperature -40℃~+40℃, pollution degree Class Ⅳ, altitude ≤4000m, long maintenance-free period.
一、产品详细描述（Product Description）
35kV 户外配网中，对油田、矿山、工业园区、乡村电网等重要负荷，双电源与隔离功能是保障供电安全与检修安全的核心。传统单断路器 + 外置隔离开关方案，存在接线复杂、互锁不可靠、安装成本高、易误操作的痛点。
ZW32-40.5GG/630 双隔离双电源手动柱上真空断路器，采用一体化设计，将真空灭弧、双侧隔离、机械操作与双重互锁深度集成，无需额外配置，核心优势如下：
- 双隔离 + 双重互锁：双侧独立隔离开关，实现电源侧与负荷侧完全隔离；机械 + 电气双重联锁，断路器合闸时隔离无法操作，隔离分闸前必须先分断路器，彻底杜绝反送电与带负荷拉闸。
- 纯手动操作，无需电源：弹簧储能手动机构，分合闸、电源切换均通过手柄完成，适合无市电、偏远山区、野外柱上场景，运维简单、可靠性高。
- 真空灭弧 + 高耐候：户外级环氧固封 / 硅橡胶套管，真空灭弧无油无气、无爆炸风险；爬电距离充足，满足 Ⅳ 级污秽，抗盐雾、抗紫外线，适应沿海、高原、重工业区极端环境。
- 安装灵活 + 全球适配：标准法兰，支持柱上垂直 / 水平安装、变电站落地安装；50/60Hz 通用，33kV/35kV 电压可选，适配亚非中东欧美澳 35kV 配网；重量远轻于分体方案，单人可配合吊装安装。
- 应用场景：偏远地区 35kV 柱上双电源线路、油田 / 矿山 / 铁路备用电源、工业园区环网柜进线、农网改造、无电区户外开关站。
In 35kV outdoor distribution networks, dual power and isolation functions are critical for ensuring power supply safety and maintenance safety in key loads such as oil fields, mines, industrial parks and rural power grids. Traditional solutions combining single circuit breaker and external disconnectors suffer from complex wiring, unreliable interlock, high installation costs and high risk of misoperation.
ZW32-40.5GG/630 Double Isolation Dual Power Manual Pole-mounted Vacuum Circuit Breaker adopts an integrated design, deeply integrating vacuum arc extinction, double-side isolation, mechanical operation and dual interlock into one unit, eliminating the need for additional components. Its core advantages are as follows:
- Double Isolation & Dual Interlock: Independent double-side disconnectors for complete isolation of power and load sides; dual mechanical-electrical interlock that prevents operation of disconnectors when the breaker is closed, and forces breaker opening before switching disconnectors, completely eliminating reverse power transmission and hot-line switching hazards.
- Pure Manual Operation, No External Power: Spring-charged manual mechanism, with switching on/off and power transfer all done via hand levers, perfect for off-grid remote mountain areas and outdoor pole-mounted applications, offering simple operation and high reliability.
- Vacuum Arc Extinction & High Weather Resistance: Outdoor-grade epoxy encapsulation/silicone rubber bushings, vacuum arc extinction with no oil or gas, zero explosion risk; sufficient creepage distance meeting pollution degree Class Ⅳ, salt spray resistance, UV resistance, suitable for extreme environments including coastal areas, plateaus and heavy industrial zones.
- Flexible Installation & Global Compatibility: Standard flange supporting vertical/horizontal pole-mounted installation and substation floor installation; universal 50/60Hz, optional 33kV/35kV voltage, adapting to 35kV distribution networks in Asia, Africa, the Middle East, Europe and Australia; much lighter than split solutions, enabling single-person installation with lifting tools.
- Application Scenarios: 35kV dual-power lines in remote areas, backup power for oil fields/mines/railways, incoming lines for industrial park ring main units, rural power grid renovation, outdoor switch stations in off-grid areas.
