Overview
The 35KV outdoor column mounted intelligent watchdog with isolated vacuum circuit breaker is an outdoor product developed by our company with international standards in the early 1990s. It can be used for control and protection of power plants, substations, electrical equipment, and power lines, as well as in places with frequent operations. It is not only used for the construction of new 35KV outdoor circuit breaker manufacturers, but also suitable for the oil-free transformation of old substations.
Product Details
35KV outdoor column mounted intelligent watchdog with isolated vacuum circuit breakerUsed for exchanging 50HZ three-phase power systems, as a means of dividing and combining load currents, overload currents, and short-circuit currents.
Products can be divided into ordinary type, anti fouling type, and plateau type according to their usage conditions
Compliant with standards: GB1984 "AC High Voltage Circuit Breakers" and IEC56 "AC High Voltage Circuit Breakers", as well as ONJ.520.023JT (Technical Conditions for Outdoor High Voltage Vacuum Circuit Breakers).
Standard product conditions:
Surrounding air temperature
Upper limit+40 ℃
The lower limit is -30 ℃ in general areas and -40 ℃ in high-altitude areas
Altitude: 2000 meters, partial pressure not exceeding 700 Pa (equivalent to a wind speed of 34 m/S), seismic intensity not exceeding 8 degrees, air pollution level III
Note: The anti pollution type is used in an environment with air pollution level IV; The high-altitude usage environment is below an altitude of 4000m.
