Product Description

Low voltage SVC automatic reactive power compensation device with Thyristor switch

ZD-DWT device is suitable to low voltage system (220V-1000V)of low power factor and harmonic pollution. The main function are  reactive power compensation harmonic depression . ZD-DWT series  adopts structure and on-off to track load variety automatically according to load characteristic and changing condition. It can remove harmonic and keep the system power factor at the best state anytime. The equipment can be found widely used among numerous machine where load changes greatly including electric welding machine, injection molding machine, rolling mill and air compressor.
The device is consisted of controller, tryristor, capacitors and reactors. The core of controller adopts DSP,  which can analyze and calculate of electric system data sampling, and create control instruction of capacitor switch, then reach target power factor. 

Module design technology. It is composed of ZD-MTK modules with intelligent reactive power compensation function.

Main features

1.Intelligent operation: it can automatically analyze and calculate system voltage, current, active power, reactive power, power factor, operate in real time automatically.
2.Harmonic suppression
3.Fast response;
4.Accurate compensation;
5.Reliable operation performance and low-cost operation.

6.Closed structure module design.

Specification

ZD-MTK Module

ZD-MTK Module for ZD-DWT Series.

ZD-MTK module is mainly composed of capacitors, reactors,Tryristor ,matched trigger circuit and high enjecting break fuse . Module can switch capacitor,suppress and filter harmonic. Make sure switching on when zero-crossing voltage, switching off when zero-crossing current,and ensure no ARC occur.

ZD-MTK Main Features

1. Enclosed module design.
2. More Safety. 
3. MoreEfficency. 
4. Fuse instead of  tranditional mirco circuit breaker,  can improve ability of switching on and off, and improve the electrical protection mechanism.
5.RS485 interface, standard MODBUS Protocol
6. No inrush current impact during the process of switching capacitor with high power. 
7.The capacitance and reactance are precisely matched and independent to each other, which can effectively inhibit a variety of high-order harmonics and protect the circuit and capacitor from impact damage.
8.There are two groups of capacitors in the module, which can realize any combination of co-compensation and sub-compensation. The centralized combination and decentralized control  ensure the 3-phase tend to an ideal balance ,and ensure the stability of voltage supply after compensation.
