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. Adopting vacuum arc-extinguishing technology, the product completely eliminates environmental pollution caused by SF6 gas leakage, complying with global low-carbon development trends, 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, 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.
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, with a mechanical life of more than 10,000 operations, no frequent maintenance required, and further reduces operation and maintenance costs. The circuit breaker is widely used in 10kV urban and rural distribution network trunk lines, branch lines, 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.
