Outdoor 36kV GCB SF6 Gas Circuit Breaker Substation Type With Long Service Life

Outdoor 36kV GCB SF6 Gas Circuit Breaker Substation Type With Long Service Life

Quick Detail: Indoor high voltage vacuum circuit breaker

DINGLI 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.

Standards And Service

The GCB circuit-breakers comply with the IEC 62271- 100 standard as well as of other major industrialised countries.

They have undergone the tests indicated ensure service safety and reliability of the apparatus in alll installationsThe

mechanical and electrical locking devices have been provided to prevent incorrect operations and to carry out nspection

of the installations while guaranteeing maximum operator safety.
