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:Industrial switching power supply which brand is good, including imported.
Mingwei, Heng Fu, Mao Shuo, Huawei, Kang Su, Nova, a joint, and so on, too bad to say
Q:EPS emergency power supply and DC screen is one thing, what is the difference between the two?
DC screen [1] is a short description of the DC power supply operating system. Universal name for the intelligent maintenance-free DC power supply screen, referred to as DC screen, universal model for the GZDW. Simply put, the DC screen is to provide a stable DC power supply equipment. (Directly converted to DC220V or DC110V when inputting 380V power supply, and input directly to battery power when input (mains and standby) are input - DC 220V or DC110V: it can be said to be an industry Dedicated emergency power supply). Power plants and substations in the power of power supply are now used in DC power supply, which for the control load and power load and DC accident lighting load to provide power, is the basis of contemporary power system control and protection. The DC screen is composed of crossover power unit, charging module unit, step-down silicon chain unit, DC feed unit, power distribution monitoring unit, monitoring module unit and insulation monitoring unit. It is mainly used in small power plants, hydropower stations, substations, and other users of DC equipment (such as petrochemical, mining, railway, etc.) for power substation and sub-circuit. Electrical protection and fault lighting and other occasions.
Q:What is the frequency of electricity in Bangladesh?
Bangladesh voltage (V): single phase 230, three phase 230/400, frequency (Hz): 50.
Q:Industrial electricity (380V) what the color of the wire, which is the line of fire, which is the zero line
Zero line of fire: zero line Fire line refers specifically to the power supply lines, electricity supply voltage of 220 volts (V). It includes a zero line [N] and a fire line [L], zero line ground (ground is zero) so called the zero line. FireWire, is the circuit power transmission line. Zero line, mainly used in the working loop, from the transformer neutral point after grounding lead the main line.
Q:Meizu special mobile power is which brand?
Meizu official did not move the power supply products, but before iWALK brand is designed for Meizu out of a 2500 mAh white mobile power, you can go to Jingdong Mall search.
Q:What is the allowable fluctuation range of the industrial standard power supply 380v power supply voltage?
Industrial standard power 380V is a three-phase supply voltage, which allows the deviation of the nominal system voltage of 10% of the taxi, that is divided into: 342--418V.
Q:Multimeter measuring industrial furnace box and power supply resistance is 6-15mΩ, which is leakage it?
your equipment team safety requirements are not standardized, if you can answer, that is irresponsible to you.
Q:Industrial control system power supply Why is the choice of DC24V power supply? Why not 17V? 11V?
regardless Is 2V lead-acid battery or commonly used 1.2V, 1.5V, 3V battery are good combination. With a series of standards to be in a timely interchangeable thing.
Q:S-350-12 monitoring dedicated switching power supply 12V29A transformer connection
12V switching power supply connected to the positive and negative, then the power will not burn, and most of the output is not, if it is a new power supply, then you can change one. The next time to pick up the first time with a multimeter to measure whether there is a short circuit, the best one of a power, on a power out of an image, no image and then check.
Q:Military grade power supply, industrial power supply, civil power supply where the difference?
Military-grade power supply, demanding, such as waterproof, fire, drop and so on are required,
