ZW8-12 Outdoor High Voltage Vacuum Circuit Breaker with Metering Transformers is tailor-made for 10kV outdoor power distribution scenarios. Its core advantage lies in the integrated design of “switch + metering”, which meets the dual needs of line protection and energy metering, simplifies the layout of the power distribution system, and reduces installation and operation and maintenance costs. Toepassing van vakuumboog-blustegnologie, the product completely eliminates environmental pollution caused by SF6 gas leakage, voldoen aan wêreldwye laekoolstofontwikkelingstendense, with fast arc-extinguishing speed, long electrical life and stable and reliable breaking performance.
The equipment is equipped with high-precision metering transformers (CT/PT), featuring high metering accuracy and small error. It can accurately collect line current, voltage and energy data, support remote meter reading and load monitoring, and provide precise data support for power operation management and electricity fee calculation. No additional independent metering equipment is required, which greatly saves the investment of the power distribution system. The product adopts a special outdoor sealed structure with a protection level of IP67, wat strawwe weer soos swaar reën effektief kan weerstaan, sand en stof, lae temperatuur en hoë temperatuur, aanpas by 'n wye temperatuurreeks van -40℃~+60℃ en 'n toepaslike hoogte van ≤4000m, meeting the needs of different outdoor scenarios.
With a compact structure and light weight, the product adopts outdoor pole-mounted installation, which is convenient for on-site construction and later maintenance. Equipped with a high-performance spring operating mechanism, it has small operating energy and sensitive action, met 'n meganiese lewe van meer as 10,000 bedrywighede, geen gereelde onderhoud nodig nie, and further reduces operation and maintenance costs. The circuit breaker is widely used in 10kV urban and rural distribution network trunk lines, taklyne, special power distribution circuits of industrial and mining enterprises, and grid connection points of photovoltaic/wind power new energy stations, making it an ideal equipment for realizing distribution network intelligence and metering precision.
