1.Brief
Introduction
Type LW**- /T outdoor H.V. A.C. dead tank SF6 gas circuit breaker
is a new kind of circuit breaker with self-blast interrupter and
spring operating mechanismon the basis of technology of product
imported from Mitsubishi, Japan.The latest achieve—arc
extinguishing principle of gas-blast pressure adapting with
breaking-current is employed,by which most of energy required for
breaking rated short-circuit current are acquired from arc
itself.Therefore, the demand for operating power is reduced
significantly. The three pole interrupters are placed inside three
metal enclosures respectively. The circuit breaker can be
mechanically three-phase gang-operated. Both remote electrical
control and local manual control can be realized. Type CT**-II
spring operating mechanism, provided with the product, is a kind of
mechanism with low operating power, minimum maintenance work needed
and high reliability. The product reaches international advanced
level in the respect of main technical
performance.
LW**- **5/T passed the prototype appraisal by former Machinery
Industry Department,Electricial Power Industry Department and
National Science & Technology Committee in December
***8.

3.Main Features and
Advantages:
3.1.Thanks to excellent electrical field design and its perfect
coordination with motion characteristics, breaking capacitive
current may be without restrike. As for special breaker for
switching capacitive load,back-to-back capacitor  bank
breaking current may be up to ***0~***0A.
3.2.Gas-flowing characteristics is so appropriate that its breaking
inductive current has no chopping overvoltage. As
for special breaker for switching inductive load, shunt reactor
switching current may be up to ***0~***0A.
3.3. When breaking rated short-circuit current and any fault
current,there are reliable breaking perfor mances
and
abundant arcing time differential through application of
arc-extinguishing principle of gas-blast pressure
adapting
breaking current.
3.4.There are excellent insulation performances sand wide range of
internal insulation margin.For *0.5kV product,the insulation level
is corresponding to that of *2.5kV,which is used at decreased
voltage.
3.5.Duration of rated short-time withstand current is as long as 4
seconds.
3.6.Due to high strength of outgoing porcelain and low gravity
center of interrupter by horizontal configuration, the product has
a high seismic-withstand performance with earthquake density of 9
degree.
3.7.The product is entirely provided with latest advanced type CT*0
spring operating mechanism.So it has low
noise level,high mechanical reliability and mechanical three-phase
gang-operation,and requires smaller space
occupied,compared to that of normal single-phase operated circuit
breaker, specially suitable for urban power
networks and rural power networks retrofit
projects.
3.8.After full routine test at factory,each circuit breaker is
packed in a whole form with 0.*5MPa SF6 gas filled in
interrupter.Only some connection and re-fill of SF6 gas are needed
on site,resulting conve nient commission. Maintenance work is
minimized,which only needs to check SF6 gas gauge and apply
lubricant.
3.9.The frame is such designed that the products are specially
suitable for retrofit projects of replace ment of
bulkoil
circuit breaker,such as type DW***5,DW****5 and DW***5,etc,bulk oil
circuit breakers, without foundation
reconstruction. Intermediate frame on support of type LW****0.5 SF6
gas dead-tank circuit breaker is specially
designed so that the product can be installed directly on original
foundation of former bulk-oil circuit breaker.Thus
the
work for retrofit engineering is reduced greatly and project cycle
becomes short.
