ZW10-12GG outdoor high-voltage dual power for each unit
I. Overview ZW12-12 series outdoor high voltage vacuum circuit breaker is a three-phase AC outdoor high voltage switchgear equipment, mainly for 12KV grade, rated current 630A, rated frequency of rural power grids, urban and mining, railways, ports and distribution system of 50HZ particularly suitable for outdoor overhead lines, division and load current, overload current, short circuit current on the grid switching and protection. Breaker according to user needs equipped with isolation switches, voltage transformers can be installed inside the product as an operation power supply. Total overall structure of the present phase breaker box, housing seals, internal use of a composite structure, with anti-condensation, anti-contamination features, high insulation level. ZW12-12 outdoor column vacuum circuit breaker is a combination of ZW10-12 breaker and isolation knife combination, called a combination of circuit breakers, disconnect switches can serve as use. This series of actuator for the CT23 type spring energy storage actuator, divided into electric and manual together. Second, the use of environmental conditions 1, ambient air temperature: up to +40 degrees, the lower limit of -40 degrees; 2, elevation: ≤2000m (if the altitude increases, the rated insulation level corresponding increase); 3, air pressure: less than 700Pa (quite wind speed 34m / s); 4, seismic intensity: less than 8 degrees; 5, pollution class: Ⅳ grade; 6, the maximum daily temperature: no more than 25 degrees; 7, relative humidity: daily average of not more than 95%, on average not more than 90% in August, non-flammable, danger of explosion, chemical corrosion and severe vibration. Third, the model and the meaning
