product information
Product name: ZW7-40.5 outdoor vacuum circuit breaker
Category: high voltage components
Product introduction: ZN7-40.5 outdoor high-voltage true master circuit breaker is used in AC 50Hz, voltage 40.5kV three-phase power system, as a function of breaking and closing load current, overload current and short-circuit current.
Overview of ZW7-40.5 outdoor vacuum circuit breaker
The ZN7-40.5 outdoor high-voltage true master circuit breaker is used in a three-phase power system with an AC 50Hz and a voltage of 40.5kV. It is used for breaking and closing load currents, overload currents and short-circuit currents.
Main functions of ZW7-40.5 outdoor vacuum circuit breaker
a. Using vacuum arc extinguishing, strong breaking capacity, long electrical life, and mechanical life of 10,000 times;
b. Simple structure, rabbit maintenance, long period of non-overhaul
c. Good insulation performance, strong anti-fouling tree;
d. It can be equipped with spring or electromagnetic operating mechanism, with reliable mechanical performance and frequent operation; no fire and explosion hazards;
e. Built-in current transformer, the instructor's accuracy can reach 0.2 level, which can realize three mutual protection;
f. Condensation controller is included, which can keep the circuit breaker running reliably at a certain temperature and humidity.
Environmental conditions for use of ZW7-40.5 outdoor vacuum circuit breaker
a. Ambient air temperature: upper limit +40℃, lower limit -30℃;
b. Altitude: ≤2000m (if the altitude needs to be increased, the rated insulation level will be increased accordingly);
c. Wind pressure: no more than 700Pa (equivalent to a wind speed of 34m/s);
d. Amplitude: earthquake intensity 8 degrees;
e. Pollution level: Level III;
f. Daily temperature difference: no more than 25℃
