| GZS1 type of metal-clad draw-out switchgear |
|
| 一、Brief instruction |
 The GZS1 Indoor metal-clad draw-out
switchboard (Herein after called as
switchboard) made in Anhui Xinlong electrical
company is a assembled electrical power
distributing equipment for AC. 3.6 ~12
KV, 3 phases, 50Hz, signal or double
bus-bar system, mainly used in power
distributing system of Elec. Power plants,
power transmitting work-net, industries
and secondary substations as receiving
and distributing equipment or as a controlling
or protecting or supervising equipment
of starting H. voltage motors, and so
on. The switchboard meets with IEC298,
GB3906 standards, having had many features
that preventing circuit breaker truck
from being pulled out with load, preventing
the circuit breaker from being mal-operated
by close or open, preventing persons
from entering into live chambers and
preventing earthing switch from being
closed when main breaker is closed.
The switchboard is equipped with VS1
vacuum breaker or EV12 vacuum circuit
breaker of Schneider Co. or VD4 vacuum
breaker of ABB Co. as Main breaker or.
The switchboard is reliable and high
electrical performance electrical distributing
equipment. |
