110kV 126kV GIS SF6 Gas Insulated High Voltage Switchgear Metal
Clad Switchgear
NINGBO TIANAN (GROUP) CO., LTD.
General:
All requirements, which are nowadays usually specified for modern
and advanced switchgear with respect to performance and
reliability, are met by GIS
type (ZFW-126/T250040)for rated voltages of up to126 kV.
Characteristics:
Δ Compact Structure
Three -phase-one enclosure design, compact structure with 0.8m
clearance between bays and save muchspce.enclosure design
Δ Flexible Arrangement
Standardized and modularized design, flexible layout, suitable for
all kinds of single-line diagram
including single busbar, double busbar, line transtormer, bridge
type diagram, 1.5 circuit breaker diagram.
Δ New Arc Extinction Design and Excellent Breaking Ability.
Gas pressure resistance and moving parts mass have been
dramatically reduced thanksto the circuit breaker's unique thermal
expansion room + auxiliary puffer design.Breakingcapacity of arc
extinguisher has been greatly reinforced because energy of arc has
beentultaken advantage of due to improvement of breaking speed,
jet orifice, pressure cylinder and other components of arc
extinguisher.
Δ Environmental Friendly
Based on environmental friendly concept and with ISO14001
system,good looking outine. no radiation, and no pollution, this
product is suitable for all kinds of conditions.
Δ Three-work-position combined switch of disonnecting(DS) and
earthing(ES)
With busbar(line) three work position disconnecting/earthing switch
,it can realize three positions: connect, disconnect and
earthing.Quantity of parts is reduced,reliability of products is
enhanced, and interlock of DS and ES is assured because of
combination of DS,ES and busbar.
Δ Basin type insulator
Stress on the basin type insulator has been improved,
electromagnetic radiation leakage aluminum has beem prevented and
external enclosure induce voltage
has been resisted thanks to aliminum outer ring structure.
Δ High reliability operation mechanism
Gas free and oil free of circuit breaker has been realized because
of application of easy to operate and easy to maintain electric
spring operation mechanism.
Operation mechanism is of very high reliability because it is anti
wear and is free from influence of temperature.
Δ High insulation reliability
High insulation reliability has been assured because conductors and
insulators are all enclosed in the earthing metal enclosure without
being influenced by the outer
environment.
Δ Excellent anti- earthquake ability
Thanks to its low weight center; light weight and compact
structure. this product has anexcellent anti- earthquake ability.
Δ Standard and easy to install
Designed and manufactured strictly in accordance with IEC and GB
standards, this product's structure and reliability is excellenty
standardized and modularized.
After assembly and test, it will be packed and shipped directly as
a whole product and this will resulted in a short installation
period.
Δ Low noise and easy to maintain
Since no compact air is needed tor operation mechanism of circuit
breaker ,disconnecting switch and earthing switch,the operation
noise is exemely low.Since SF6 performs well and damage of arc
contact caused by opening and breaking arc is very low.this product
also is very easy to maintain.
