Voltage Circuit Breakers and DeaeeesPARS switcH FP gas type circuit breaker which uses puffer system for oxtinguishing the arc, 4s a dual axial blast circuit breaker so it cools the arc more quickly and effectvely. This feature in addition to remarkable thermal properties of SFe gas causes an instant reduction in the arc Volume increases theif time of the are contacis and also the circu breakey's life time, FP circuit breakers are manufactured under French ALSTOM company's license wth the highest quality accordng to IEC 622 71-100,BS 5311, VDE 670, UTEC 64100 standards and can be delivered : » With rated voltage from 7.2 KV 10:36 KV,rated current from 630 to 2000 Aand breaking capacity from 16 to 31.5 KA. (Accordig to the table in the last pages) With front or side command arrangement © With primary over current relay. 2 With pressure switch for supervision of gas pressure of the poles 2 With withdrawable connections. SF6 gas as an excellent dielectric substance : ‘The remarkable dielectric properties of tho sulphur hexafluoride in comparison with other dielectric substances such as air and oil, its ability in absorbing and transfering thermal energy of the arc together wit its high performance makes SFe gas an ideal dielectric substance for circuit breakers and causes a substantial reduction in the dimensions of these circuit breakers. Electro negativity of SFs gas is an important factor in reducing the are intensity caused by switching that increases the circuit breaker's life time. SFo gas has a high chemical stability and in this way it has a life time as long as the circuit breaker's life time ‘Thermal Conductivity wim.k Temp.0 ” Breakdown Voltage (30 Hz) 120 100 : 80 s =F 6 1 : o AR 1 20 | 0 02 «03 Ot Gas Pressure Mpa (abs) ee NSFP GG gi Oy Glas Wayne go UaS pl Seek (dal axial Blast) oy2 239 poe LI pa ndelage 9 ge Ball ee ok ee by See spl) SB US ba Ole | sls te a SF6 38 JG Jil > leo nat Job HIB Us ee eS oe Jae Jyh and 239 sh classe 133 Ss i Las pled cng FP yt ANS Glad aI ilar Cok oy SUL, ALY TEC62271-100.B85311.VDE670.

FP type circuit breaker is equipped with floor rollers and can easily be installed in withdrawable cubicles 2 Gas valve is easily accessible and the gas pressure can be inspected by a conventional manometer ® Because of the low normal filing pressure of the poles (3.5 bars at 20'c) the operation of the circuit breaker is in perfect safety. Since the poles are apart from each other, itis possible to replace every defective pole with a new one in the shortest possible time 2 To have more security in the event of any abnormal overpressure, each pole is Coat ee neem se, provided with a special safety bursting membrane . ® Toassure the quality of SFs gas each pole is provided with absorbant substance which absorbs any other gases caused by switching operation . ® : : - ey PPO AUS fp solace INTERNAL PARIS OF FP POLE ©@ = ® @ \ 1 - UPPER LINE CONNECTION © ' 2.

In order to regulate the gas pressure in a temperature more or less than 20°C the injection of the gas should be performed according to the front graph. Pressure switch for FP poles: There is a place for mounting of pressure switch on the bottom of the FP poles to operate for the lower pressure than normal which is mounted acc. to the request of customer . This switch could be double step. In this case the first switch operates in 2.9 bars for issuing alarm signal and for more reduction of gas pressure the second switch trips the C.B. it should be mentioned that the pressure switch terminals are available for customer and could be used acc. to the protection system design. et ads Gk © SFE GLE LE 4 TEC slate! oat ps CAS L FP doe Shp ep Ca JLT /0 Ole ln ate (ladda SSL ays Yo BN pals PW hosel > a 1S Slr aah SL Lol Sal Relative pressure in bar 4 apts i pln! ‘Temperature inC eof cal lz ce FP Spa Gl lb > Siglo s Je I Sl gi al > baie ds P/O dep ae J iS Ls Selig 53 Ap ag Coal ue aes os Fete Spa hes eee ch Ese ey cul Bir aeecioas XS Sey Sie gene Mali Wiring workshop for C.B. control cireuit & Pressure switchFP circuit breakers are equipped with BLRM operating mechanism which utilizes energy stored in the springs is of a high reliability and its maintenance is limited to lubricating of moving parts. Because of its extraordinary abilities, BLRM mechanism is also used in high voltage circuit breakers and can be charged both manually or automatically( using a charging electromotor ), This mechanism has many accessories such as tripping coil, closing coil, electromotor for charging, auxiliary contacts (6 No +7 Nc),anti pumping relay and can be equipped with under voltage system, pressure switch for monitoring the pressure of the gas inside the poles ace. to the customer 's request. Primary Relay Installation on FP C.B. In adcition to the possibility of using of secondary relays the design of FP C.B. and its poles are suitable for installation of any kinds of primary relays which protect the network against overcurrent & short circuit. In case of increasing the current and becoming over than set value on the relay, tripping command will transfer to open it. Since the primary overcurrent relay getting the needed energy for its performance from the network and it is not necessary to use another source,the FP C.B.s with primary relays are tested in the factory before delivery from the accurate performance point of view. ELECTRICAL ENDURANCE: The optimum design of FP C.B. causes the minimum arc energy- low arcing contact wearing and long electrical endurance. The value of interrupted current is the main parameter for electrical endurance and for inspection of arcing parts of poles the front graph should be considered. ‘BLM operating Mechanism FPCB. with primary relay Number ot breaks.
