 ZHW-145 Hybrid Gas Insulated Switchgear (hereinafter referred to as HGIS) belongs to

three-phase AC high-voltage transmission equipment and is in three-phase box type structure. The

core part circuit breaker adopts self-energy arc-extinguishing principle equipped with the spring

mechanism. It is applicable to 145kV electric system, and used to cut off the load current and fault

current, convert and isolate lines, measure current and voltage, and protect overvoltage, etc. It

assembles all the primary equipment in the substation within the grounding metal shell, except the

power transformer, and then constitutes an integral as per the main wiring requirements of users,

and then it is filled with SF 6 gas as the insulation and arc-extinguishing medium. It connects to the

external power grid via lead-out bushing or cable connection devices.

 

1. When comparing ZHW-145 HGIS with conventional power station, it has many advantages,

such as small floor area, reliable operation, long repair cycle, excellent electrical properties, and

no external influence. It is a popular high-voltage electrical product in urban power grid

transformation and heavy pollution areas and highly reliable substations

 

2. GIS can meet the requirements of the national standard GB7674-2008 Gas Insulated

metal-Enclosed Switchgear with Rated Voltage of 72.5kV and Above, and the international

standard IEC 62271-203: 2003 high-voltage switchgear and control equipment—Part 203 Gas

Insulated metal-enclosed Switchgear with Rated Voltage of 72.5kV and above.

 

Operating environmental conditions

a) Installation site:: outdoor

b)Ambient environment: -40°C to + 40°C

c)Altitude:  (merely for the lead-out bushing) : less than 1000m

d) Icing thickness: 10mm

e) Pollution grade: III and IV

f) Earthquake intensity:AG5

g) Wind speed: less than  34m/s;

h) Places without flammable, combustible, chemical corrosion and violent vibration.
