ZMZ-J type intelligent integrated low-voltage filtering capacitor is mainly applied to locations where the harmonic current is 40% spodaj (kot je frekvenčni pretvornik, in ostalo opremo), it not only
meets the requirements of reactive compensation and improving power factor, ampak tudi odpravlja vpliv harmonike visokega reda na sistem, izboljša kakovost električne energije.

Product Function Filtering

It effectively suppresses high-order harmonic and surge, tvori kanal z nizkim uporom za visoke harmonike. Absorbira in sprošča harmonike, odpravlja vpliv harmonike visokega reda na kondenzator, ščiti vezja in kondenzatorje pred preobremenitvijo, preprečuje pregrevanje kondenzatorjev, izolacijski medij pred staranjem, avoids reduction of self healing performance, or reduction of service life.

No-surge switching

Matched with special capacitor switching switch, no switching surge.

Split-phase compensation

Capacitor of each phase of separate-phase compensation type product can be switched separately, which improves the reactive compensating accuracy, enables the three-phase reactive unbalance to be well compensated.

Measurement

Measurement of distribution voltage, trenutno, reactive power, power factor; automatic measurement and correction of CT phase and change; measurement of three-phase current and inside temperature of each capacitor.

Protection

Quick current switching and over-current protection of circuit; over-voltage and under-voltage protection of capacitor; over-temperature, open-phase and three-phase unbalance protection of capacitor, when the temperature of capacitor exceed 65℃, the whole machine of capacitor would exit operation, which improves its service life, and guarantees safety running of system.

Signal

Switching state, over, under and compensation state, over and under-voltage state signals; protection operation type and self-diagnose fault type signals.

Komunikacija

Adoption of RS-485 communication coupling between capacitor and controller, which is convenient for uploading of mass of sampling data as well as information exchanging with external monitor terminal, forms system work.

Online

Functions of wire network communication and radio network communication.

Intelligent network control

It is able to detect and track the reactive variation of system automatically, and switch in capacitor bank automatically. Carry out switching circularly for capacitors with same capacitance, and carry out switching according to the vacancy for capacitors with different capacitance. The capacitor that is switched in earlier should exit first,that exits earlier should be switched in first; capacitor whose running temperature is lower should be switched in first, whose running temperature is higher should exit first; when the compensation situation is stable, the capacitors should be switched in circularly every fifteen minutes, avoid long time running of any one capacitor.

Self-diagnose of faults

Intelligent control element of capacitor will carry out self-diagnose to the running parameters of the body, once there is self-inspection fault, the whole machine responses quickly and exit running.
