Product feature:
A. It has package structure and is assembled by nuts with rivet and
bolts with high intensity. The enclosure is made of 2.5mm zinc
steel sheets coated with aluminum by imported from Switzerland
without surface treatment. The material of the door is high quality
steel sheets by resin toner electrostatic spraying. It is featured
by beautiful looking, resistance to impact surface, anti-corrosion,
good antioxidation, high mechanical intensity and easy installation
as well as easy maintenance.
B. The steel sheets are bent by imported numerical equipments,
which made the body is light than the same kind of equipment, and
with good mechanical intensity, high accuracy, easy assembly as
well as realizing the unify of the materials.
C. It has middle mounted structure, which enlarge the cable space
and makes the height of cable installation to **0mm as well as
makes it possible for the switchgear to connect with multiple
cables6 single core cables at most.
D. Unload the middle clapboard and load and unload clapboard of
busbar room, which make such activity occur on the face of the
switchgear very convenient, as the connection of main busbar, the
installation and examine and repair of cable, earthing switch,
lightning arrestor and current transformer etc.
E. Each HV compartment is completely isolated. On each ceiling of
them there is a compression release passage, which ensure that the
internal arc fault doesn\'t influence the compartment nearby and
the equipments and personnel are safe. All the HV/LV compartments
are well sealed. The instrument room is fitted in automatic
condensation controller. And the HV compartments are fitted in
plate shape heating device to make the surface of the insulator dry
inside the switchgear. And the body is fitted in
light.
F. The moving contact and static contact of circuit breaker room
adopt bridge type multi-point connection type to ensure the safety
of contact and large range of temperature rise as well as big
creeping insulation piece and large-size cable room and busbar room
space, all above make it possible for the switchgear to work on the
bad condition.
G. It can be operated while closing. The normal operation of the
switchgear must be done under the condition of HV compartment door
is closed in order to ensure the safety of the personnel, including
opening/closing of circuit breaker, the trolley of circuit breaker
is pulled to the working position and exits to testing/ isolating
position and the opening/ closing of the earthing
switch.
H. Combined truck and insulating structure of body, it makes the
interlock safe, reliable and flexible. The trolley has breaking
position, testing position and working position inside the
switchgear. Each position has orientation device to make sure the
reliability of the interlock.
