Judgment and treatment of inverter short-circuit fault characteristics - Delixi

(1) Gain Parameter: The share gain of the speed manipulator. If the gain is too large, it may cause speed fluctuations. (2) Integration time parameter: the integration time of the speed manipulator, that is, the change rate of the output signal of the manipulator under the deviation step signal. The shorter the integration moment ...

The analog output of Delixi inverter is abnormal, and the operating frequency of the inverter does not match the output of the controller? Solution(s): First, you should determine what hardware is going wrong. Make the controller enter the manual debugging situation, respectively...

　　Seriously affect the normal operation of the inverter. The core components of the inverter are IGBT power semiconductor switching components. When they are working properly, they generate a lot of heat. If there is no fan forced cooling, the sensing head will immediately detect (IGBT) overheating (IGBT) and send it ...

It is selected according to the type of load current in the circuit. AC loads should be selected AC contactors, DC loads should be DC contactors, assuming that the control system is mainly AC loads, DC motors or DC loads have a small capacity, AC contactors can also be used to control, but the contact of the ...

Although this is not a common problem of AC contactors, the inability of AC contactors to engage will affect the efficiency of the operation and even damage the production equipment.

The type of inverter is selected according to the type of production machinery, speed regulation range, static speed accuracy, and starting torque requirements, and it is most appropriate to decide which inverter is the most suitable to use. The so-called suitability is not only easy to use, but also economical, to meet the basic conditions and requirements of technology and production. ...

1. Trial delivery and commissioning method The first thing to find is the fault of the remaining current action maintainer itself. The detailed operation method is: first block the power supply, and then remove all the zero-sequence transformer load side leads of the remaining current action maintainer (the second and third level remaining current action maintainers will directly remove the outgoing ...

1. The safety wire is blown off In a general environment, a blown safety wire indicates that there is a problem with the internal wiring of the power supply. Because the power supply is operated in the shape of high voltage and high current, the fluctuation of the grid voltage and the surge city cause the current in the power supply to increase suddenly and cause the safety wire to be blown off. The focus should be on checking the power ...

1. Classification of switch operation organization At present, the switches we encounter are generally divided into many types, such as oil-rich type (old model, now you can't see it at all), oil-poor type (some user stations also have it), SF6, vacuum, GIS (combined electrical appliances) and so on. These are all about the arc extinguishing medium of the switch. ...

The following options are available on the output side of the drive: 1) Output reactor, when the length of the cable output from the inverter to the motor is greater than the specified value of the product, the output reactor should be added to compensate for the charging and discharging influence of the coupling capacitor when the long cable of the motor is running, so as to prevent the inverter from overcurrent. Output ...

The disconnector is a kind of switching equipment that is mainly used for "blocking the power supply, reversing the operation, and connecting and blocking the small current circuit", without arc extinguishing function. When the barrier switch is divided into directions, there is an insulation distance between the contacts that meets the specified requirements and a significant disconnection mark; When in the azimuth, it can carry ...

1. Appearance Genuine Delixi switch shape is more fashionable, looks elegant and beautiful, and the surface is neat, impact resistance is relatively strong, will not briefly crack or yellow. And most imitations will turn yellow after a period of use...

Problem Description: The pressure of Delixi inverter system is unstable, simple vibration? Solution(s): The pressure of the system is unstable, which can be due to the following reasons: A. The position of the pressure sensor to collect the pressure of the system is ...

1. If the two branch lines are connected, the current in the zero line flows to each other, which destroys the operating current balance in the zero sequence current transformer and causes the leakage maintainer to malfunction. If you want to use the neutral line of the power branch line as the neutral line of the lighting branch line nearby, it will cause the leakage of the power branch line.

EM61 series inverter has optimized open-loop vector control, V F control, stable performance, optimized function, standard equipment for users, and can also expand multi-channel I-O interface and communication function, which is a compact low-power model. ...

1. Circuit breaker refers to a switchgear that can turn on, carry and turn off the current under normal circuit conditions and turn on, carry and turn off the current under abnormal circuit conditions within a regular time. According to the voltage of Delixi circuit breaker, there are high-voltage circuit breakers and low-voltage circuit breakers. Below 1kV ...

In the process of practical speed regulation, an ordinary frequency-adjustable communication power supply can not meet the requirements of speed regulation and control of asynchronous motors, and must also take into account the effective use of the motor magnetic field, the suppression of the starting current and the acquisition of the desired torque characteristics, such as low-frequency torque characteristics.

Thermal relay is a maintenance appliance used for overload maintenance of electric motors or other electrical equipment and electrical lines. In the actual operation of the motor, if the machine is in abnormal condition or the circuit is abnormal, the motor will be overloaded, the motor ...

There are also several types of quasi-sine waves, ranging from square waves, which are almost indistinguishable from square waves, to rounded trapezoidal waves, which are relatively close to sine waves. We're only going to talk about square waves, which are the waveforms that most commercially available high-frequency regulators can supply today. ...

Delixi intelligent all-round circuit breaker CDW9 series, should be checked regularly every year, first open and close and long-distance equipment, successively use a variety of additives, test operation program column, control unit test using a small test suite; Every two years or when the control unit repair target reaches 100, it should be ...
