Product Description

PFI Plant Power factor improvement plant with compound switch: ZD-DWM Series

Compared to our ZD-DWT series, in ZD-DWM we use compound switch instead of Thyristor.ZD-DWM device is suitable to low voltage system of low power factor, harmonic pollution. The main function is harmonic depression and reactive compensation. Device adopts structure and on-off to track load variety automatically according to load characteristic and changing condition.It can remove harmonic pollution and keep the system power factor at the best condition anytime. ZD-DWM is a great breakthrough in the development of capacitor banks. With detuned reactor inside, no harmonic occure,no harmonic enlarge and no resonance danger, work stably in distribution system. Generally,ZD-DWM can absorb,suppress harmonic.
Module design technology. It is composed of ZD-MMK, modules with intelligent reactive power compensation function.

ZD-MMK Module

ZD-MMK Module for ZD-DWM Series.

The module is mainly composed of capacitors,reactors,combination switch and high break capacity fuse. Module not only can switch capacitor banks,but also have function of suppressing harmonics and filtering harmonics. Select reactors with different reactance rate for different high harmonics. For example, 7% reactors for 5th harmonic, 7% reactors for 3rd harmonic.
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.
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.
Enclosed module design.

Features
1.The capacitance and reactance are precisely matched, which can effectively surppress a variety of high-order harmonics and protect the circuit and capacitor. 2.Realize the independent switching of co-compensation and sub-compensation, improve the precision of switching
2.RS485 interface, standard MODBUS protocol, computer remote monitoring, history recording function. Set parametre easily and use manual switching rapidly.
3. Rapid production,installation and service because of simple wiring,module design and capacitor banks installation.
4.Fuse instead of tranditional mirco circuit breaker, improve ability of switching on and off, and improve the electrical protection mechanism.
5.Enclosed module design. Realize the standardization and modularization of products
