BAM(BFM)High Voltage Shunt Capacitor (High Series)

Code and implication

Application

High voltage shunt power capacitor mainly use in 50Hzor 60Hz Ac power system .improve power factor,reduce reactive power loss,mend voltage quality,plenitude elaborate generate power 's equipment and supply power equipment efficiency.it is national recommend save power products.

Working conditions

• Altitude is not more than 1000m,ambient temperature:－40/B, B type is most temperature is +45℃.
• Installation condition:there is no strong vibration,no harmful gas and vapor, no conductive or explosive dust.
• Power capacitor will work in the good ventilate condition, it would not permit to work in sealing and no ventilate condition.
• Power capacitor connection wire should take soft conductive wire,the whole circuit connect well.

Structure Features

1. Power capacitor is made up by case and core, the case is made up by thin steel sheet weld,output porcelain was welded on the case top,the case beside was welded hook,one side hood was put ground bolt.
2. Power capacitor core is made up by some component and isolation together.component is made by two piece aluminum foil centre clip film paper compound media or full film media press wind and staved .core's component connect by fixed strand and shunt way,so can satisfied different voltage and capacity.
3. The power capacitor with inside fuse ,every component have one fuse,when any component was punctured,other component will well and it can discharge,so it can make the fuse off in very short time.you take off the faulty component,then the capacitor still work.
4. Three phase power capacitor is star connection.
5. Liquid medium was in power capacitor,immerse liquid fill up the inside gap.and it take excellent electric physic property,it has good solubility with other material.

Main Technical data

• Rated voltage: 6.3kV,6.6kV,6.6/√3kV,10.5kV,11kV,11/√3KV. 12KV,12/√3KV,19kV and so on.
• Rated capacity: 30~334kvar other voltage and capacity will make according to the client demanding.
• Capacity tolerance: -5%~+10%.
• Power loss tanδ:film and paper compound medium tanδ<0. 08%,full film medium tanδ <0. 05%.
• Withstand voltage:between power capacitor,every pole can afford AC 2. 15 times voltage or direct 4. 3 times rated voltage ,it will over 10 s,there is no puncture and flash.
• Dielectric level: 6KV 30kv 10kv 42kv testing AC,it will over 1 min there is no puncture and flash.
• Discharge property:the power capacitor with inside put discharge register.it can reduce the left voltage from√2Un peak value to below 75V within 10 minute when the power is off.
• Max permit over voltage: 1. 1 times rated voltage the most permit voltage would not more than 8hours with in 24 hours, 1. 15 time rated voltage,he most permit over voltage would not not more than 30 minute within 24 hours 1. 2time rated voltage would not more than 5 minute within 24 hours, 1. 3 time rated voltage would not more 1 minute within 24 hours.
• Max permit over current:over current is not more than 3 time rated current,it can work,if over current transition,you should consider over voltage capacity tolerance and harmonic affection would not more than 1.43 times rated current.
• Confirm standard: GB/T 11024.1-2009 or IEC60871-1: 2005.

Ordering Information

• Power capacitor rated voltage choosing should consider net circuit voltage,and consider power capacitor input can increase the voltage,so choose the rated capacitorRWF0. 75-voltage less than 5% of net circuit voltage;when power capacitor circuit have strand reactor,capacitor terminal voltage will increase according to relative reactor radio.so when you choose the power capacitor rated voltage you should calculate the reactor ratio.
• Power capacitor is channel which harmonic is low resister.when the harmonic enter the power capacitor,it make power capacitor to over current and over voltage. In addition power capacitor will make harmonic enlarge then will happen resonance ,it will effect electric net safe and it will shorten the power capacitor life,so there is big harmonic condition,power capacitor will connect with reactor to use together
• When power capacitor cut off,the surge current is hundred times of rated current.so choose power capacitor switch,you should choose no puncture switch.it can restraint cut surge,and connect reactor which has restraint.
• When the capacitor which has discharge resister inside cut off the power,it can reduce the rated voltage from peak to below75V within 10 minute.if you need cut off the power the rated voltage from peak to below 50V,please notice it in the order.
• The capacitor was used in circuit compensate, 150-200kvar is suitable in any place,please notice the power capacitor and transformer would not mix install.it not permit use the same line fuse cut out avoiding no full phase wok which it make magnetic resonance to create over voltage and over current to damage the power capacitor and transformer.
• Choosing protect operate over voltage surge arrester:power capacitor special surge arrester,and it should put the centre of the power capacitor pole.
• Choosing power capacitor special fuse cut out,rated current is 1. 42~1. 5 time rated current which is better
• When power capacitor was connect with high voltage electromotor,leading up the capacitor terminal voltage is high than rated voltage in order to protect the electromotor self exciting after cut off the power.so capacitor rated current is less than neuter current 90% of electromotor,when the electromotor take Y/A connection way,it is not permit which put the capacitor on the electromotor directly,you should take special connection way.
• When the power capacitor was use in more altitude 1000 or capacitor using in wet and hot place,you should notice when you order it.
• Special type or special requirement capacitor,you should notice when you order it.
