With the development of the electric power industry, now the electricity has been accompanied by every detail of our days, so the maintenance of the electric power industry, began to get more and more attention from everyone, because the circuit in the daily operation side, very simple because of overvoltage or undervoltage and present a certain problem, which ...

1. Electrical equipment will produce higher harmonics when it produces abnormality and deterioration, and the abnormality and deterioration of motors, loads, and inverters are used to distinguish the higher harmonics from 2 to 40 times, and the data is changed by FFT, and the analysis is made on the basis of the analysis data of long-term savings.

Don't worry about the damage of the frequency conversion, disassemble the machine after the discharge; It is indispensable to ask for a diagnosis and clarify the problem at the beginning of the test; Input and output PN junction, three-phase balance and then unshelling; Look at the nameplate before powering on, the wrong voltage will blow up; The bus has no electricity to see that it is safe, and the rectifier filter is wrong ...

(1) Evaluate the safety control level that the machinery and equipment need to reach (2) Confirm the type of input signal to be monitored and (3) the number of input signals that need to be monitored (4) The number and type of channels that the module needs to output (5) Whether it is necessary to control the output device (such as ...

RM4 Series Control Relay (Three-phase Power Control) RM4 series voltage steerable relays RM4 current operated relay RM4 level control relay RM17 three-phase power controller RM35 3-phase power control relay RM17 Voltage Steerable Relay ...

The inch movement in Schneider inverter means that the control signal can drive the motor intermittently according to the certain rules, and the motor acts in strict accordance with the dynamic and stop instructions of the control signal, and the motor does not roll by inertia during the shutdown. It's like moving an inch and then stopping. The full name of Schneider inverter is "...

Schneider Electric has announced the launch of its Pacific Foundation, which will provide financial and advisory support to charitable foundations in the Pacific region to address fundamental human rights issues of access to energy. Four foundations were selected as the Foundation's initial recipients.

1. What is the difference between high-voltage inverter and low-voltage inverter? Frequency converters can be broadly divided into two categories: high-voltage frequency converters and low-voltage frequency converters. In terms of use, the applicable objects are different, and the high-voltage motor is the same from the principle of speed regulation. From the topology ...

The foot switch series is XPE, and it should be noted when selecting: 1) Raw materials: metal and plastic, which are used in heavy-duty, high-risk, light-duty, low-risk occasions. 2) Pedal: divided into single pedal and double pedal (type end plus D). 3) With or without maintenance cover ...

1. Check whether all switches are in the disconnected position; 2. Check whether there are foreign objects in the UPS uninterruptible power supply cabinet and transformer; Check whether the flat cable connection is correct and whether it is loose; 3. Check that the connected plug is ...

Sensitive operation form, satisfactory business operation policy: Four-level inverter technology: Galaxy VX uses innovative patented four-level inverter technology to reduce power consumption and pressure on power components, and complete the perfect unity of high power and component reliability. Sensitive operating form ...

1. What is a control loop? The network that supplies the control signal to the main circuit that supplies power to the asynchronous motor (voltage and frequency can be adjusted) is called the control loop. Second, the composition of the control loop The control circuit is controlled by the frequency ...

The orifice flowmeter is a high-range ratio differential pressure flow device composed of a standard orifice plate and a multi-parameter differential pressure transmitter (or differential pressure transmitter, temperature transmitter and pressure transmitter), which can measure the flow rate of gas, steam, liquid and natural gas. Widely used in petroleum, chemical, metallurgy, electric power ...

The troubleshooting method of the electrical control line is not the same as a thousand people, and various methods can be used cooperatively, but do not copy the rigid set. In general, investigative research can help us to find out the problem. The experimental method can not only find out the fault phenomenon, but also find the fault location or fault circuit; Logic...

When there are high-frequency impact loads such as welding machines, electroplating power supplies, electrolytic power supplies, or slip ring power supply near the power supply system of Schneider inverter, the inverter itself is simply protected due to interference. It is recommended that users choose the following methods: ...

To repair the output board driven by the inverter, we must first investigate whether the components on the PCB board are burned out, replace them first, and then analyze what causes the burned out and deal with this problem. And then...

In the process of connecting the line of the inverter, it is necessary to pay attention to the following aspects: 1. The power supply must be connected to the main circuit power terminal L1/R, L2/S, L3/T, if the power supply is connected to other terminals by mistake, the inverter will be damaged. 2. It is necessary for the grounding terminal to be well connected.
