UniSafe 36 HD4 Circuit Breaker Upper terminal Nozzle Main contacts Arcing contacts Moving part Elektrik Sanayi A.S. - Page 20 The auto-puffer technique jointly operates as a pure puffer device up to 30 % of the rated breaking current and as a self-blast device at higher values soft switching no chopping current no overvoltages (lower than 2.5 P.U.)
UniSafe 36 HD4 Circuit Breaker The circuit-breaker is closed Nozzle I Upper terminal Main contacts The current flows from the upper (fixed) terminal to the moving part through the main contacts. Arcing contacts Elektrik Sanayi A.S. - Page 21 Moving part
UniSafe 36 HD4 Circuit Breaker Opening of the main contacts I Elektrik Sanayi A.S. - Page 22 1- no leakage from the nozzle as it is blocked by the fixed arcing contact 2-no leakage from the cylinder of the moving arcing contact as it is blocked by the fixed arcing contact 3- the upper chamber is connected to the moving mechanism and its volume remains the same during the downstroke (dead volume) 4-the only changing volume is the one of the lower chamber, whichdecreases during the downstroke of the moving contact 5- this puffer is designed to avoid chopping currents by means of a dead volume higher than the compressed volume. As the gas flows towards the upper chamber, the pressure level is equal to the ratio between the dead volume and the lower chamber volume. The moving part goes down thus separating the main contacts. There is no arc striking as the current keeps flowing from the upper terminal to the moving parts through the arcing contacts. During the downstroke, the moving part exert a pressure on the gas housed in the lower chamber; the pressure increase generated in the lower chamber opens the connection valve of the upper chamber. The compressed gas flows from the lower to the upper chamber thus taking both enclosures at the same pressure level.
UniSafe 36 HD4 Circuit Breaker Opening of the arcing contacts I The breaking chamber undergoes the following process: Elektrik Sanayi A.S. - Page 23 At low currents: as the current hits the natural zero and the arc is quenched, the gas flows from the dead volume to the inside of the moving contact. The low pressure guarantees the absence of chopping currents and the small quantity of gas involved is sufficient to restore the dielectric strenght between the two contacts by avoiding, at the same time, the re-strike of the transient recovery voltage At higher short circuit currents: the pressure wave of the arc propagates like a supersonic wave, increasing the gas pressure which closes the valve between the two chambers. From this moment on, the device starts working as a pure self-blast, the gas overheating and the molecular dissociation due to the high temperature increase the pressure in the dead volume. Said pressure is proportional to the arc and the resulting gas flow guarantees the quenching at the first passage through zero natural current. The current keeps flowing due to the arc generated between the fixed and moving contacts. The gas cannot leak either from the nozzle as the hole is blocked by the fixed contact or from the inside of the moving contact because of the arc clogging effect.
UniSafe 36 HD4 Circuit Breaker Circuit-breaker in the open position Elektrik Sanayi A.S. - Page 24 The arc is quenched; the lower chamber reaches its minimum volume and its maximum pressure level, kept by the valve locked by the supersonic wave. As the self-generated pressure of the dead volume decreases, due to the outflow of the gas through the moving contact, the valve re-opens. From now on, a new jet of fresh gas flows in and makes the temperature of the contacts sink. At the same time, the gas flows through the nozzle, free from the fixed arcing contact. The cleaning of the arcing chamber by means of fresh gas makes the device suitable for another reclosing and the interruption up to the maximum breaking capacity.
