1. Type recognition: Recognize whether the type of inverter is common with the type of inverter purchased. 2. Transportation acknowledgement: After opening the package, check whether the inverter is damaged during transportation. 3. Voltage recognition: the power supply voltage on the site should be borne by the inverter.

In the transformer planning process, the choice of wiring method is often not paid attention to. The three-phase transformer has A/B/C three-phase winding on the 1/2 side. The connection between them has a great impact on the operation performance of transformers, especially distribution transformers, and directly affects the quality of power supply. Therefore, the wiring ...

Drives power and operate commercial and industrial motors, and thermal protection is necessary in accordance with their planning and operating environment. The main advantages of the frequency converters are flexible handling, smooth start-up and shutdown functions, and significant energy savings due to centrifugal fans and pumps operating under variable loads. ...

Circuit breaker failure maintenance refers to the relay maintenance action of faulty electrical equipment when the trip command is announced and the circuit breaker refuses, the maintenance action information of the faulty equipment and the current information of the rejected circuit breaker constitute the judgment of circuit breaker failure, and other related problems in the same plant and station are cut off in a shorter time limit.

Nowadays, the function of domestic inverters is becoming more and more mature, with a wide variety and dazzling. Many brands have been tested by the market, but there are also some brands that have been imitated and counterfeited to disrupt the market. One of the major characteristics of domestic brands is that they are both like domestic brands and imported brands. The brand's ...

In addition, it is unscientific to select the inverter body alone, without considering whether the inverter selection and capacity matching are appropriate. ...

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 ...

1. The control accuracy of the vector type is higher than that of the general-purpose type. 2. The vector type has a large output torque at low speed, which can make the motor get a larger starting torque, which is suitable for application in the occasion of heavy load starting, such as: high-power long belt, hoist, etc. If used in some of the more common fields ...

1. Power system: The wire and cable products selected in the power system mainly include overhead bare wires, busbars (busbars), power cables (plastic cables, oil-paper power cables (fundamentally replaced by plastic power cables), rubber cables, overhead insulated cables), branch cables (replacing part of the busbars), ...

A kind of pressure reducing valve in instrumentation refers to a kind of equipment used to control the pressure value. Pressure reducing valves are usually used in water-related categories, because from the perspective of the transmission medium, the transmission medium of the equipment is mainly water, but we all know that water is a thing that will ...

The interference encountered by sensors and instruments in the field operation is varied, and the specific situation is analyzed on a case-by-case basis, and the principle of anti-interference is to adopt different methods for different disturbances. This flexible and mobile strategy is undoubtedly opposed to universality, and the way to deal with it is to choose a modular approach, except for ...

1. Defective device The lead wire of each pile head is not firmly connected and loosened for a long time, which will cause the pile to heat and oxidize, burn out the outer insulation of the wire, and announce sparks and burnt smell, forming undervoltage of the line, and the air switch action. 2. The leakage switch does not match the load The actual electricity load of the home is large ...

The Schneider ATV610 inverter is suitable for specification loads and can be used in a wide range of industries and infrastructure. Including: petrochemical, power plant, industrial and civil buildings, water treatment and sewage treatment, HVAC, thermal heating, constant pressure water supply, and other applicable occasions. In these jobs ...

The output frequency of the inverter set by the user according to the needs of the production process. For example: the original power frequency power supply of the fan motor is now transformed into frequency conversion speed regulation, you can set the given frequency to 50 Hz, and there are two ways to set it: one is to use the operation panel of the inverter to input the digital quantity of the frequency 5 ...

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.

(1) It is necessary to choose a four-pole switch: For the sake of repair safety: in the TT grounding system, the total equipotential bonding is done on the user side, but because the total equipotential bonding at this moment does not include the neutral wire, the line fault (for example: a phase wire grounding) occurs on the grounding electrode on the power supply side.

1. The first step is to check whether the inverter is connected to the line, and whether the wiring of the control line and the power circuit is correct 2. Next, turn on the power of the inverter, enter the motor parameters, and perform motor identification 3. Next, set the function parameters to launch the ...

AC inverter is the result of the high development of microcomputer and modern power electronics technology. The microcomputer is the center of the inverter, and the power electronics form the main circuit of the inverter.
