Product descriptions from the supplier
Summary
ROCKWILL® Electric strives to bring our customers the latest technology and competitive pricing and best service for distribution automatic.
RHB 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 GSH 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.
Breaking technique
The breaking principle of RHB circuit-breakers is based on compression and self-blast technique to obtain top performances at all breaking current values, with minimum arc times, gradual arc extinction without chopping, and no restriking or switchingovervoltages.
This breaking technique - already widely appreciated and used in high voltage circuit-breakers, has been introduced into medium voltage with the HM4 series circuit-breakers for indoor installation.
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, thereby 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 RHB 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 all installations.
The mechanical and electrical locking devices have been provided to prevent incorrect operations and to carry out inspection of the installations while guaranteeing maximum operator safety.
