Used For Full - Function Intelligent Reactive Power Compensation Device in Distribution System

Product overview

The full-function intelligent reactive power compensation device is suitable for power system with rated voltage of 400V and frequency of 50Hz. It is used to improve power factor and adjust three-phase unbalanced current, improve power supply quality and reduce energy loss. It is mainly used with integrated distribution box.

Fyux-0.4 full-function intelligent reactive power compensation device is mainly used for supporting the comprehensive distribution box (JP cabinet), specifications of 60kVAR and 120kvar60kvar reactive power compensation device is mainly composed of 18 capacitors, 18 groups of synchronous composite switches, 18 branch insurance, 1 controller, 4 transformer inlet terminals, 3 arresters, 1 circuit breaker Apparatus and cabinet, etc.

The 120kvar reactive power compensation device is mainly composed of 36 capacitors, 36 groups of synchronous composite switches, 36 branch insurance, 1 controller, 4 transformer incoming terminals, 3 lightning arresters, 1 circuit breaker and cabinet body.

Main functions and features

1. Fine reactive power compensation by small differential classification

The fine reactive power compensation device adopts the compensation mode of fine fully controlled phase complementation plus phase ground sub-complementation. The compensation control output is 18 channels and 36 channels respectively, and the unbalanced active current regulation is taken into account.

2. Synchronizing a Composite Switch Group

Capacitor switching adopts synchronous composite switch group, which has the advantage of zero crossing switching through coding switch, realizing no inrush current in input, no arc light in excise, and no harmonic pollution in switching.

3. Comprehensive switching criteria of voltage, current, reactive power and power factor

Sampling signal is three-phase voltage, three-phase current, according to voltage, current, power factor, reactive power, active power comprehensive judgment automatic compensation, to avoid switching oscillation and reduce the compensation zone, giving consideration to reactive compensation and three-phase unbalanced current regulation.

4. Small Wireless "Four Remote"

In the case of no network signal, it can be remotely controlled within 10 meters by handheld terminal to check the running status and real-time data of the device, and view and modify the fixed value. Reserved remote communication interface, can realize the remote "four remote" function.
