The supply capacitor BWF/BFF/BFM/BAM12 / √ 3-334-1W

High voltage shunt capacitors / High-voltage shunt capacitor structure ● capacitor mainly by the shell and the borders of the bases, and the outlet casing composed housing made of sheet steel or stainless steel plate welded cover welded bushing on both side walls are welded for installation, lifting the crane climbing, the borders of the bases by the elements, insulating parts. Components useful polypropylene film as medium and the volume made of aluminum foil (plate) or medium with aluminum foil rolls made of polypropylene film capacitor paper. ● high voltage shunt capacitors inner join general form of a single-phase, when the user needs to provide three-phase products. ● HV shunt capacitor internal each component string fuse, timely removal of the individual breakdown of the components to ensure the normal operation of the capacitor overall. ● HV shunt capacitor built-discharge devices, allows the capacitor to disconnect the power after the residual voltage in 10min by 2Un drops below 75V. According to the needs of the purchaser, allows the device to be reduced to a lower voltage in a shorter time. Environment installation and operation areas altitude does not exceed 2000m, the plateau type capacitors altitude areas above this limit. Installation area ambient air temperature range of -25 ~ +45 ℃ -40 ~ +40 ℃. Outdoor (indoors General) use, the installation site should be free of harmful gases and steam, there should be no conductive or explosive dust should be no severe mechanical vibration. Orders can request applies to the special environmental conditions. Operating over-voltage and over-current switching capacitor switching heavy breakdown may occur when the first peak is not greater than 22 times the applied voltage (root mean square value), the duration of not more than 1/2 cycle transition overvoltage. The corresponding transition overcurrent peak may reach 100In. In this case, allowing the operation 1000 times per year. When the need for more frequent operation of the capacitor, the steady-state magnitude of the voltage and duration of the transition the current should be limited to a lower level. Its limit by the manufacturer and purchaser negotiated. The main technical performance ● capacitor continuous operating voltage 1.00Un, and time and can be run in the following table under steady-state overvoltage. ● capacitor tolerated without being significantly damaged overvoltage value depending on the duration, the total number of times and the temperature of the capacitor. ● The following table is higher than 1.15Un overvoltage in a total of no more than 200 times to determine the premise occur during the lifetime of the capacitor. Power frequency voltage maximum duration 1.10Un long term refers to the highest long-term over-voltage should not exceed 1.10Un 1.15Un the every 24h 30min system voltage adjustment and volatility voltage raised 1.30Un 1min light load of 1.20Un 5min ● allow due The over-voltage and higher harmonics caused by the effective value of 1.30 times the rated current of the steady state running under overcurrent. Capacitance of the capacitor with the largest positive deviation, steady-state current is allowed to reach the rated current of 1.43 times. ● Capacitance tolerance: -5% to +10%. ● loss tangent values ??tarδ (rated voltage at 20 ° C when) a medium of film and paper products is not greater than 0.0012. full film dielectric is not greater than 0.0005 (excluding internal fuse). capacitors with internal fuses loss tangent values ??determined in consultation when ordering. ● capacitors indoor and outdoor, and suitable for the humid tropics, highland areas and polluted areas with special environmental products. ● product technical performance meets GB3983-89 GB/T11024-2001 high and low voltage shunt capacitors national standards and requirements lEC871-1 (1987).
