Low voltage intelligent reactive power compensation cabinet

Because this device can effectively improve the power factor of power load, reduce the line loss, improve the actual negative transformer Load ability.
has the remarkable energy saving effect, at the same time, using a specific reactor in the system, also can prevent effectively Harmonic amplification.
effectively absorb most of the harmonic current, harmonic voltage total abnormal rate limit and every harmonic current content Value in accordance with national standards, achieve the goal of harmonic governance. And if you use ordinary contactor for capacitor group, Will bring a large surge current. the slow compensation time, high maintenance cost, and short service life and cause This, we recommend that users in the following occasions.
to give priority to use dynamic reactive power compensation device.

Ordering information

Power compensation principle: Perceptual load of power grid(generators. choke coils, transformers, induction heater and electric welding machine. etc.) will produce different degree of electric hysteresis, the so-called inductance. Inductive load has a voltage change direction can still keep curent solution(such as positive)
characteristics of a period of time, Once there is the phase difference between the current and voltage, can produce reactive power, and feed back to the grid. In ac power grid(50/60 hz), the above process repeat 50 or 60 times per second, thus an obvious solution is to direct the perceptual power electricity(reactive power) through the capacitor to temporary storage and release, thus reducing the power grid reactive power exchange.

Model and meaning

Condition of use: 1. environmental temperature:-5℃~+40℃
2. environmental temperature: no more than 90%(20℃)
3. altitude: not more than 2000m
4. and the surrounding medium no explosion danger.no enough to damage and corrosion of metal Body, no conductive dust, installation is not easy to violent vibration, no snow and rain erosion.

Technical data: 1.the system voltage AC450V
2.cutting time: t 20 ms or less
3.input flow: <25 In
4.rated frequency 50 hz plus or minus 50%
5.sampling current: 0-5A
6.the machine power consumption: 15 w or less
7.sensitivity: 100mA

Technical data: 1. the color MCU/digital signal into the principle, DSP as the control unit:
2. overvoltage, undervoltage, grid voltage harmonic overrun by excision capacitor;
3. when the grid lacks rapid removal of capacitor, and alarm;
4. self-checking function, ensure that every time after the electricity output circuit in the off state;
5. power, data protection, all the data when the power is retained with more than one year home monitoring network parameters, harmonic and reactive power compensation and protection warning, and other functions.

Product features: 1. the general performance is strong.The compensation tank can be combined with various random cabinet put oneself in another's position at home and abroad，such as MNS and houndreds types product as like GCK，GGD.etc；
2. capacitance compensation combination variety flexible.With Y type compensation mode，delta type compensation mode，Y+delta combined compensation mode；
3. communication diversity.With communication interface RS-232/485，wireless data transmission module and GPRS module implements the ong-distance communication；
4. accurate safety control.A voltage zero crossing trigger，when no surge current zero input resection，breaking does not produce high pressure；
5. long service life，under the free maintenance，a service life of more than 100000 hours.

System principle example

Ordering information: 1. main circuit diagram;
2. compensation capacity and compensation mode;
3. is not consistent with what conditions of normal use of a description in advance.
