ZW8-12 type outdoor high voltage vacuum circuit breakers, commonly
known as Zhu on the switch , the Department of rated voltage 12KV,
50Hz outdoor high-voltage power distribution equipment. The circuit
breaker complex sets of insulated , side-mounted parade motivation
enough , easy to maintain , does not apply to an altitude higher
than 2000m, excluding the oil spills, leaks and other problems, is
one of the best products for outdoor power distribution system.
With over- current protection , anti- surge controller can achieve
inrush current delay and instantaneous overcurrent , short quick
break trip function ; station , opening and storage can be manual
or electric operation and remote operation ; controller can be
equipped with FTU achieve distribution automation, controllers can
also be equipped with heavy weight sets consisting tuner .
Product Features :
Three-phase circuit breaker box structure , the unique design of
rain , outdoor sealing problems breaker .
Ceramic vacuum interrupter chamber interrupter interrupter using
goblet longitudinal magnetic field , strong arcing ability contacts
using a special material , effectively inhibited the operation
Other insulated with silicone rubber , silicone rubber
hydrophobicity good, strong anti-aging properties , with anti-
condensation , strong anti-contamination performance, etc., while
increasing the creepage distance between the outer surface ,
effectively ensuring the
Absolutely sash performance.
Cabinets composite insulation ( dry insulation ) . Between poles
and pole insulated cover for the use of SMC insulation ; station at
the junction box is sealed with a seal at the bottom of the well
casing is equipped with moisture
Agent , to ensure the drying air cabinets .
Three-phase linkage, in the state of isolation switches gate
obvious visible fracture between isolation switch and circuit
breaker interlock to prevent misuse and prevent units with load
isolation switch , circuit breaker in the station gates
Isolating switch can not be operated when the state before the
operation when the circuit-breaker status disconnectors , circuit
breakers and beneficial overhaul .
Circuit breaker can be equipped with five single-coil current
transformers , protection , measurement and metering signals ,
variable ratio 50-630/5i optional .
Breaker box with spray treatment and stainless steel surface
polishing 2 ways , beautiful exterior colors, good corrosion
Operating mechanism with spring operating mechanism , with manual
operation, the operation of two electric , and with overcurrent
tripping device . Can complete a weight bench brake operation.
Products fully meet GB1984-2003, GB/T11022-1999, DL/T403, DL/T402
other domestic standards.
Xi'an high-voltage circuit breakers in the electrical testing
center through all types of tests , includingtemperature rise test
, insulation test , short-circuit breaking and off table test ,
short-term and peak withstand current test
Inspection , mechanical life, no load cable Founding test, partial
discharge test , low temperature test .
