BSMJ Cylindrical Low Voltage Shunt Capacitor Of The Self Healing Type

BSMJ Cylindrical Low Voltage Shut Capacitor Of The Self-Healing Type​

Code and implication

Structure features

• Taking cylinder aluminum case.
• Immerse liquid: no social effects of pollution dielectric oil.
• Inseting press detaching equipment and dischargeelectric resister.
• Capacitor core is healing good quality metallized film.
• Bottom is M12 or M16 install ground bolt.
• Three phase capacitor is inside Δ connection way.

Application

BSMJ cylinder self healing shunt power capacitor was used in 50Hz or 60Hz low voltage system equipment,it has power factor adjust ,it was suitable in normally field compensator and centralize auto compensate,it can reduce reactive power loss, improve voltage quality, it is national recommend saving electric products.

This product meets the standard: GB/T 12747,IEC831-1/2.

Working conditions

• Power capacitor should confirm left voltage reduce to rated voltage 10% to input again after the power was cut off ,normally it will need 200s almost. so it would choose the power controller which has input and reput lock time function after cut off the power.If choose normally power controller, it must install speediness discharge power equipment.it would not limited which use adopting same electric factor input and chip switch.
• Altitude level is not more than 2000m.
• Temperature type: -25/C low temperature,highest temperature is C type (it would not more than 50℃the average of temperature is not more than 40℃within 24 hours, one year average of temperature is not more than 30'C) ,power capacitor will work within good ventilate condition, It would not permit within sealing and installation condition.

Main Technical data

• Rated voltage: 0. 23kV,0. 25kV,0. 4kV,0. 415kV,0. 45kV,0. 48kV,0. 525kv and so on.
• Rated capacity: 1-30kvar
• Capacitance tolerance: -5%~+10%
• Power loss tan δ≤0. 1%
• Between pole voltage: 2. 15 times rated voltage is 5 second,no permanence puncture or shine
• Dielectric level: between cover add the voltage : 2 times rated voltage plus 2KV or 3KV ,please take height continue 10 second,no puncture and shine
• Max permit voltage: 1.1 times voltage ,every 24 hours is not more than 8 hours,1.15 times voltage ,every 24 hours is not more than 30 munites 1.2 times voltage,it would not more than 5second (continue) 1. 3 times voltage,not more than 1 minutes.
• High permit current:it is permit to work within less than 1. 3 times rated current ,as there are over voltage and capacitor positive deviation and harmonic the over current is not than 1. 43 times rated current.
• Discharge component:inside put discharge register,capacitor cut off power ,than discharge 3 munites electric,so the voltage reduce to 50v.
• Standard: GB/T 12747-2017, IEC 60831-2002
