aon、产品描述（Product Description）
ZW20-12G/630A-20户外柱上高压真空断路器，专为10kV户外柱上配电场景量身设计，以真空为灭弧介质，彻底杜绝SF6气体泄漏带来的环境污染，Ag teacht le treochtaí forbartha ísealcharbóin domhanda。设备采用户外专用密封结构，防护等级达IP67，可有效抵御暴雨、沙尘、低温、高温等恶劣天气，适配-40℃~+60℃的宽温环境，适用海拔≤4000m，满足不同户外场景的使用需求。
产品采用柱上安装设计，Struchtúr dlúth、重量轻便，节省安装空间，便于现场施工与后期维护；Feistithe le meicníocht oibriúcháin earrach ardfheidhmíochta，操作功小、动作可靠，机械寿命可达10000次以上，无需频繁维护，大幅降低运维成本。该断路器额定电流630A，额定短路开断电流20kA，具备优异的开断性能和绝缘性能，可广泛应用于城乡配网改造、工矿企业配电、光伏/风电新能源电站配套、铁路及机场等重点设施的10kV配电线路保护与控制，为电力系统的安全、Cobhsaigh、高效运行提供可靠保障。
ZW20-12G/630A-20 Outdoor Pole-Mounted High Voltage Vacuum Circuit Breaker is tailor-made for 10kV outdoor pole-mounted power distribution scenarios. With vacuum as the arc-extinguishing medium, it completely eliminates environmental pollution caused by SF6 gas leakage, complying with global low-carbon development trends. The equipment adopts a special outdoor sealed structure with a protection level of IP67, which can effectively resist harsh weather such as heavy rain, sand and dust, low temperature and high temperature, adapting to a wide temperature range of -40℃~+60℃ and an applicable altitude of ≤4000m, meeting the needs of different outdoor scenarios.
The product adopts a pole-mounted installation design with a compact structure and light weight, saving installation space and facilitating on-site construction and later maintenance. Equipped with a high-performance spring operating mechanism, it has small operating energy and reliable action, with a mechanical life of more than 10,000 operations, no frequent maintenance required, and greatly reduces operation and maintenance costs. With a rated current of 630A and a rated short-circuit breaking current of 20kA, the circuit breaker has excellent breaking performance and insulation performance. It can be widely used in urban and rural distribution network transformation, industrial and mining enterprise power distribution, photovoltaic/wind power new energy station supporting facilities, and 10kV distribution line protection and control of key facilities such as railways and airports, providing reliable guarantee for the safe, stable and efficient operation of the power system.
