High voltage reactive power automatic compensation equipment

Integration structure Complete assembly Compact structure Convenient maintenance Stable quality, long service life

TBBZ high voltage reactive power automatic compensating equipment (hereinafter referred to as equipment) is suitable for 10KV and 6KV distribution circuit, installed on the overhead circuit, to improve power factor,reduce circu it consumption, save electric energy and improve the voltage quality, besides, it is also used for reactive compensating of 10KV busbar of miniature terminal tr ansformer substation and compensating high voltage motor on the spot.This equipment conforms to the standard JB/T7111-1993 High Voltage S hunt Capacitor Installation and stan dard DL/T604-1996 Specification of High voltage Shunt Capacitor Installation for Order.It is made up of drop-out fuse, voltage transformer of large capacity, high voltage vacuum contactor special for switching capacitor, current transformer,ZnO arrester, whole-film high voltage shunt capacitor,automatic c ompensa ting c ontroller of high voltage capacitor, box body and so on.

Service conditions

Altitude: not higher than 1,000mWind velocity: not more than 35m/sEarthquake: intensity of earthquake can't exceed 8 degree.Sunshine: max amplitude is 0.1w/cm2Ambient air temperature: -40 ~+45 ;Chemical conditions: no harmful gas and steam, no electric conductive orexplosive dust.Pollution-proof capability: leakage distance of outer insulation is 2.5cm/kVInstallation: the gradient is not more than 5 degree.The harmonic content of installation site shall conform to the national relevantregulations.Note: If the products are used in the plateau area or special environments,user shall negotiate with us separately.

Characteristics

It has following highlight features: integration structure, complete assembly, compact structure, convenient maintenance,stable quality, long service life and so on. According to practical requirement, user can set the parameters. Its microcomputercan judg e and a nalyze automatically, automatic switching of high voltage shunt capacitor bank can be reali zed. Furthe rmor e,the equipment has perfect protection functions suc h as quick- breaking pr otection ag ainst busbar short-ci rcuit, capacitorover-current short-time delay protection, over voltage protection, under voltage protection, phase failure protection (Theprotection functions can be chosen).

Performance

Capacitance differenceThe differen ce of actua l capacitance and rated capacitance of equipment is within the range 0~5%of rated capacitanceDischarge performanceAfter power is off for 10min, voltage of each group of capacitors is lower than 50V.
