Product Brief

Fr-zcs series intelligent capacitor is a new generation of reactive power compensation equipment with high efficiency, energysaving, line loss reduction, power factor improvement and power quality improvement in 0.4kV low-voltage distribution network. It consists of intelligent measurement and control unit, synchronous switch circuit, line protection unit and two (△ type)low-voltage power capacitors. Instead of the conventional automatic reactive power compensation device composed of intelligentcontroller, fuse, composite switch or mechanical contactor, thermal relay, low-voltage power capacitor, indicator light and other
loose parts in the cabinet and the cabinet surface connected by wires. It has changed the structure mode of the traditionalreactive power compensation device, which is bulky and bulky, so that the new generation of low-voltage reactive powercompensation device has the characteristics of better compensation effect, smaller volume, lower power consumption, cheaper price,more cost saving, more flexible use, more convenient maintenance, longer service life and higher reliability, which adapts to thehigher requirements of modern power grid for reactive power compensation.

Functional characteristics

Improving power factor, saving energy and electricity, improving power grid

Zero crossing switching

The voltage zero crossing input, the current zero crossing cut-off and the switching inrush current are very small, which greatly
improves the voltage resistance, the current impact and the power consumption of the equipment, and reduces 80% of the energy
consumption in the conventional capacitor cabinet

Realization of voltage zero crossing temperature protection
(matching)

The built-in temperature sensor of the self-healing low-voltage power capacitor can reflect the internal heating of the capacitor
under the conditions of over-voltage, over harmonic, large leakage current and high ambient temperature, so as to realize over
temperature protection. After exceeding the set temperature, the capacitor will be automatically cut off, and the capacitor will
be out of operation, so as to achieve the purpose of protecting the equipment

Split phase compensation (split phase intelligent capacitor)

The single-phase compensation is realized to solve the imbalance of three-phase load, and the single-phase compensation with large
reactive power deficiency is carried out to achieve the optimal compensation effect.

intelligent network

When multiple capacitors are connected to the network for use, one becomes the main control capacitor and the other is the
auxiliary control capacitor without setting, which forms the automatic control system of low-voltage reactive power. If some slave
machine fails, no switching action will be taken, which will not affect the other work. If the main machine fails, the other
capacitors will automatically generate a new main control capacitor through the time sequence competition, forming a new main
control capacitor New system; capacitors with the same capacity are switched according to the principle of cycle switching, and
capacitors with different capacities are switched according to the principle of adaptation; 485 communication interface can be
connected to the background computer for integrated distribution management

Block structure

The products are standardized and modularized, replacing the traditional controllers, air switches, AC contactors, thyristors,
thermal relays and capacitors, and combining them into a whole, with small heat output. When the panel is installed, the building
block stacking method is used. When the capacitors are damaged, the simple single unit is only needed for quick replacement

Wiring is simple.

With the installation of multiple capacitor panels, the production time is reduced by more than 60% compared with the traditional
mode, and at the same time, the connection line is reduced by 80%, and the nodes are reduced by 80%. The cabinet is simple and can
be assembled quickly on site, which greatly improves the production efficiency of the complete set of plants

Easy expansion

The product is small in size and simple in wiring. With the increase of power load of the consumers, the number of capacitors can
be increased at any time, which changes the conventional mode. Due to the complex wiring and unchangeable limitations, it can
adapt to the needs of enterprise development and can be invested by stages

Convenient maintenance

LCD Chinese display protection action type, including over-voltage, under voltage, small current, over temperature, voltage
harmonic, current harmonic and other protection; intelligent capacitor has self diagnosis function, which can reflect the above
faults on the LCD, which is conducive to on-site fault finding. The product has an overall warranty of one year. When the
capacitor is damaged, it only needs simple and rapid replacement of the single unit to realize maintenance free

Remarkable effect

Ensure that the system voltage is stable and qualified; improve the power factor and predict the input capacitor. If the input
capacitor is over compensated, it will not be input to avoid fines due to over reactive power; control the reliability by 100%,
improve the active output of distribution transformer, reduce the capacity increase investment, reduce losses and save energy
