Product Description

Outdoor Substation Type SF6 Gas Circuit Breaker With High Breaking Capacity

 

Quick Detail: 

General
ROCKWILL Electric strives to bring our customers the latest technology and competitive pricing and best service
for distribution automatic GCB medium voltage circuit-breakers for outdoor installation use sulphur hexafluoride
gas (SF6) to extinguish the electric arc and as the insulating medium. Breaking in SF6 gas takes place without
current chopping or generation of overvoltages. These characteristics guarantee a long electrical life for the
circuit-breaker and limited dynamic di-electric and thermal stresses on the installation.
The GHS type of stored energy and free release mechanical operating mechanism allows opening and closing
operations through local and remote control. The operating mechanism, the activating kinematics of the moving
contacts and the anti-condensation heater are located inside a tight metal enclosure which also acts as the support
for the poles. The above-mentioned structure is supported by a frame made of telescopic metal sections which
allow the height of the circuit-breaker terminal to be adapted from 2800 mm to 3700 mm.
The metal enclosure has IP 54(*) degree of protection and is fitted with a tight door with an inspection window.
The circuit-breaker is compact and ensures a high level of sturdiness and excellent mechanical reliability.
 
The enclosure is made out of a steel plate with adequate surface protection by a special metalising and painting
process. The support structures are hot dip galvanised.
 

Main Contact Separation
No electric arc is struck because the current flows through the arcing contacts. During its run downwards, the moving

apparatus compresses the gas in the lower chamber. The compressed gas flows from the lower to the upper chamber.

hereby taking both the chambers to the same pressure.

Arcing Contact Separation
The current flows due to the electric arc which has struck between the arcing contacts. The gas cannot escape through

the nozzle because the hole is still closed by the fixed arcing contact and cannot even escape through the inside of the

arcing contact, because of the clogging effect of the electric arc.
