1、 Use

FLCK series low voltage reactive power compensation ark is u sed in low voltage power grid re active power compensation, in order to improve the grid power factor, reduce line losses, improve power quality. This series of low vo ltage re active po wer c ompensation ark with intelligent reactive power controller as the core, using the capacitance type contactor as cutting device of capacitor Banks, according to the power grid capacity,power factor, automatically ensure that always has high power factor of power grid. FLCK type low voltage reactive power compensation element for the capacitor compensation ark, can be used in the occasion of the harmonic is not high; FLCKD type low voltage reactive power compensation ark of compensation without the same as the cap acitor, but can according to each phase of the load shape in same cutting, FLCKL type low vol tage re active po wer c ompensation ark of compensating element is composed of capacitor and reactor  in  series , with  functions  of  harmonic suppression, can be used in the occasion of higher harmonic.

2、Structural characteristics of

1) The compensation tank inside the main components are capacitor, reactor (FLCKL type), knife switch, fuse,contactor (or silicon controlled rectifier), controller, etc; FLCKL type reactive power compensation ca binet according to user requirements can be modular design,namely a module set capacitor, reactor, fuse, contactor,compact structure, new layout.

 

2) The cabinet put oneself in another's position on thefront panel has a power factor me ter, amme ter,voltmeter, switch, etc., co nvenient for the use r in realtime observation and manual/automatic switching on-off switch; Cabinet put oneself in another's position at the top of the coolin g fan, controlled by th e temperature control sw itch, pa nel w ith ma nual/automatic switch control fan.

3) Cabinet put oneself in another's position is made of high quality cold-rolled steel plate, good smoothness, surface coating processing, anti-corrosion ability; Internal fra me i s ma de o f ga lvanized ste el pl ate aluminium zinc steel plate, to ensure good electrical conductivity and corrosion.

4) C omplete pro tection fu nction: a sh ort c ircuit,overload, overvoltage, undervoltage, short of equal protection; All the parameters set is convenient; When external related faults occur automatically quit running,power automatic recovery after operation.
