Product Description:

 

Technical Features:

SVC (Static Var Compensator) is composed of by thyristor controlled reactor (TCR) and passive filter (FC). It is a compensator with parallel connection in the grid, and it quickly and automatically adjust the system reactive power according to the load working condition.

 

Application Scope:

Reactive compensation and harmonic filtering of electric power, petroleum, chemical industry, metallurgy, wind power, photovoltaic power generation, hoist, electric arc furnace, electric locomotive, steel rolling production line, high voltage power lines, etc.

 

Product Principle


Combining with the control concept of current international mainstream, the heating power supply adopts the digital design to make the machine run more efficiently.

The heating power supply adopts the N + 1 redundancy technology to ensure the entire sapphire production cycle. We adopt DSP digital control mode, making the output voltage accuracy to five over ten thousand, and it has analog peripheral interface, 485 communication interface, etc. Using IGBT as power device to improve working efficiency and conform to the current trend of saving energy and reducing consumption.


Technical Features

1. Control system: We adopt American TI company DSP processor, which is of high control accuracy and high reliability. It employs PI control technology with advanced hardware and software. If there occurs fluctuation in power grid voltage, it can automatically maintain the current output power constantly.

2. HMI: It displays parameters in real time such as output voltage, current and power, etc.. It works with function of data maintained when power fails and it is easy to inquire and maintain the record of failure time and fault type.

3. High efficiency and low pollution: We adopt the phase shifting full bridge soft switching (ZVS) control technology, to realize the IGBT open and shut off under zero voltage. It greatly reduce the IGBT switching loss, the noise pollution and electromagnetic interference of the power. The output voltage waveform is completely smooth, and it runs more safe and stable.

4. High reliability: We adopt the multi-unit structure of N + 1, and the multiple units work together in normal condition. Failure of one unit does not affect the present output power and it is more convenient to maintain normal operation of equipment.

5. Perfect protection: Overtemperature protection and output over-voltage or over-current protection, output short circuit and grounding protection, the limit protection of water flow and strike fire protection, etc.

6. Flexible interface: Input and output support simulation approaches such as switch, voltage and current signal, Modbus, MB + and Profibus etc. data communications control.

Q:US Industrial Electricity Voltage
US industrial electricity as follows: US Voltage Standard (ANSI C84-la-1980): 1. The power supply system design should be carried out according to "range A". The voltage deviation range of "range B" should be rare, and it should take measures to achieve the requirement of "range A".
Q:What brand of power control module is better? You know MINMAX and C & D two brands.
Siemens, we here is used, stability and reliability is good.
Q:Power for ups power supply which well-known imported brands
APC UPS is Nixon visit to China to bring the national ceremony, huh, huh EMERSON, SANTAK
Q:Do you want to use the DC24V of the alarm system for the power cord of the bus-specific fire-fighting telephone?
I have not seen the telephone extension to use 24V power supply, are generally by the fire center bus phone host pull two pairs of lines to the bus phone module (two pairs of lines are the telephone audio line and telephone bus), and then from the phone module Pull a pair of lines to the telephone extension (this line for the telephone audio line).
Q:Led special power how to wiring
GND (three digits), then accept the light of the negative (usually black wire or white wire); 12V (three digits), then you light the positive pole (usually red wire or brown wire);
Q:Multimeter measuring industrial furnace box and power supply resistance is 6-15mΩ, which is leakage it?
All metal shell equipment require reliable grounding, whether or not you can continue to use,
Q:Why do you need to use isolated power in industrial communications?
In simple terms, the need for isolation mainly involves: communication equipment on the power of the stability and anti-interference requirements are high,
Q:Site with industrial power 380V / 50hz, electrical equipment is 110v / 60hz. Is there a solution?
Voltage problem, 380V three-phase power, 110V should be single-phase power,
Q:Dell 9020MT business computer can only use 290W dedicated power?
Yes. Dell 9020MT i7 version of the power supply is rated at 200W. 290w on the super. The rated power is the power at which the appliance is operating normally. Its value is the rated voltage of the appliance multiplied by the rated current. If the actual power of the appliance is greater than the rated power, the appliance may be damaged.
Q:Is the industrial atomizer good with a switching power supply or a toroidal transformer?
Need to be determined according to the use of the situation. Switching power supply and transformer power supply has its own advantages and strengths.
