Outdoor HV Vacuum Circuit Breaker
Outdoor HV Vacuum Circuit Breaker GENERAL:
Outdoor HV Vacuum Circuit Breaker, model ZW6-33KV, is available in
power T & D system with rated voltage of 35 kV, rated current
of 1600A, AC three phase and 50Hz. It could be used in industrial
enterprises and mines, power plant and substation for protection
and controlling, as well as interconnection circuit breaker. This
also available in places for frequent operations.STRUCTURE
This product is a kind of outdoor HV vacuum circuit breaker. Its
overall structure is a kind of knob and tube type. The vacuum arc
extinguishing room is equipped in upper procelain tube and a kind
of sliding contactor, which results in a lower circuit resistance
and good conductivity.
1?¡©The dimension of a new designed arc extinguishing room is
smaller, with a higher current breaking capacity, a higher
insulation level and a higher arc extinguishing ability, etc.
2?¡©A spring operation mechanism, model CT17-1VB, is equipped in
the operation mechanism, with advantages of a smaller operation
power, easy operation and a longer service life, etc.
3?¡©SF6 was filled in the porcelain knob and tube, so condensation
could be avoided because of a higher temperature changing and the
insulation level of the circuit breaker shall be greatly increased.
4?¡©One to 6 pieces of individual current transformers could be
equipped in this product. So this kind of product can satisfy an
accuracy requirement at varied current level. And there is not any
interference between primary single wiring and secondary wiring.
5?¡©Typical technical characters are as follows, rated
current:2000A, rated voltage 40.5kV, rated short circuit breaking
current:315.kV.
6?¡©Application range is wide(below 3000m of sea level).
7?¡©Service life shall be higher than 10000 time
