產品描述
ZW8-12G/630 Outdoor High Voltage Vacuum Circuit Breaker is specially designed for 10kV outdoor power distribution scenarios. With vacuum as the arc-extinguishing medium, it completely eliminates environmental pollution caused by SF6 gas leakage, 順應全球低碳發展趨勢. 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.
The product has a compact structure and light weight, adopts pole-mounted installation, saves installation space, and is convenient for on-site construction and maintenance. Equipped with a spring operating mechanism, it has small operating energy and reliable action, 機械壽命超過 10,000 營運, 無需頻繁維護, 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.
