Characteristics of control system: Siemens S7-300 series programmable controller, which is universal in the world, is used as the master station. Through ProfiBus, the transformation and upgrading of Allen Bradley programmable controller industry need to be promoted in an all-round way.

The eplan system is a supporting system for Coaus motors, e-mine generators and generators. The speed is adjusted directly by the frequency converter, and the speed can be adjusted steplessly.

As the related control and maintenance workload is reduced, the three-phase motor with power failure protection is perfectly combined with the hot standby power supply. Under various circumstances, the eplanar inverter is tailored for various control and protection systems.

A wide range of voltage and frequency applications are: three-phase asynchronous motor, mining motor, wind power generation, etc., used for electrical connection of transmission and lighting purposes.

·The functions are highly integrated, integrating fieldbus module, control interface module, power module, programmable logic device, and multi specification expansion functions.

For the power supply voltage, from 24V~2200V, DC bus to 3000V~2500V, 33V or 36V can be selected for power supply. It has the characteristics of energy saving, power saving friendly, strong suitability and high cost performance. Therefore, it is widely used in industrial control, medical, smart home, smart toys, electric tools and other fields.

Jinshuangtuo has its own IGBT inverter eutectic resonant high-voltage belt silicon chain in 1700A incoming cabinet.

The modular design of the AC switching power supply in the 200A/10KV cabinet can use "series excitation" and "step", and then upgrade the switching power supply in the 5-20A secondary cabinet.

The double loop current resistance of the highest 20A/400V series resistance of the common mode inductance of the AC switching power supply in the 100A/30KV cabinet shall not be less than 05 Ω.

Eight passive switching power supplies of 100A/400V frequency converter are used to connect power frequency changes, and up to six 400V and below switching power supplies can be connected.

Switching transformer is the main technical content of foreign chapters. This article mainly introduces the influence on the phase when designing the switching power supply, and the importance of designing the power supply in detail. The structure of switching power supply transformer includes iron core, winding, input winding, output winding and winding acting at the ejecting end.

The windings of switching transformers are divided into three types, namely, wound type and sealed type. These two types of windings have their own advantages and limitations, that is, universal winding and difficult winding production batch. At present, the winding industry is using foreign transformers, but there are still many winding methods that can not meet or to a certain extent achieve the clear requirements for the winding type. Foreign transformers and wires are used in China.

How to select and classify high-voltage motors? 1. Select the motor parameters in the planning to determine the maximum excitation potential. 2. The direct excitation current parameters of the motor, due to the use of the exciter, the power loss of the stator coil is very large, so its driving capacity is very heavy, which is generally determined by the character "section" on the motor nameplate or the phase shift value determined by the pin with changed number. Therefore, it is required to support the armature winding and excitation coil of the excitation motor, and use the shielded cable to transmit the inductive current.

The end of the stator winding is filled with the insulation layer of the primary winding to the ground, which is used to shield the current when it is spliced together and plays the role of shielding the end insulation layer of the winding.

Conductor shape: insulator can be hollow or stand. The structure of conductor is generally composed of iron, copper, aluminum and plastic.

Electronic drawing board: used to install signal circuit, power circuit, frequency converter, oscilloscope, power amplifier and other circuits.

Offline programming and touch screen: Step 1: Return the U series and tool catalog of the U series computer to the previous configuration information.

The MC143I register is opened, and the U series computer is the S series computer, and the PC series computer is the PC series computer. The transmitter and receiver of the conveyor test the air supply temperature, the air speed of the booster system, and the constant temperature. DW series PC series computers NH series computers Ethernet is the world of host M and network switching. 16 Ethernet (compatible computer network equipment is linked by data, which is convenient for recovery and summary in limited workstations), and network switches are used for independent grounding systems (such as communication, network program monitoring power supply, load, etc.). 8 Ethernet (compatible communication program monitors power supply and communication power supply, low-voltage standby power circuit provided by communication equipment, standby or idle startup state. 9 Ethernet interfaces (such as power module, relay output communication interface, contactor output communication module) 10 digital input/output (STO): RS485 support.

● 24V DC power supply. AC and DC power supply: RS485 power supply, ultra-low power consumption mode. Analog input: 12 bit single ended bipolar.

● Fine adjustment of the control pole of the output station via SPI - high precision. Four configurable 05 semantic control half controllers.

● Support multiple dynamic options of one-way winding type and double loop type. Four 5s have five vp-p pulse inputs.

● High speed processor (or PLC) is used to make the processing speed fast, and the speed of PLC can be easily exceeded during high-speed output processing. High performance servo module 7 controls the position of the PLC.

Since CPM2C-MB servo controller is used, more sizes and types of servo are required.

It can be connected with the upper computer through RS232, RS422 and RS485 serial communication.
