Delixi switching regulator basics

Class I refers to the circuit breaker, which is only used for maintenance and not for normal operation; The other is that circuit breakers are required together for maintenance and infrequent operation. In the latter case, the operating conditions and electrical life should be taken into account. The selection principles for circuit breakers for motor maintenance are as follows: ...

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 inverter is a device that can control the speed of the motor, and it completes the speed regulation by adjusting the voltage and frequency of the motor. When selecting an inverter, there are several factors to consider, including the power of the motor, the type of load, the operating environment, etc. This article will specifically introduce the selection of frequency converters ...

Delixi 3P air switch, rated current 630A, rated voltage 380V. The Icu=Ics=70kA of this circuit breaker. When the short-circuit current reaches 70kA, can the circuit breaker still be used? If it works, the ICU is already at its limit, which is a contradiction. If it can't be used, ICS is 70KA, which means ...

Delixi's communication contactor is widely used in industrial electrical, contactor as a kind of electromagnetic switch, its interior is mainly composed of the main and auxiliary contacts and electromagnetic coils, static cores and other parts of the control line connection and breaking. ​ ...

1. The divider is the sixth generation of intelligent machine using microcomputer chips, and the intelligent program is very high. 2. Single-phase three-phase connection, the divider on the market is scored as A, B, and C three-phase wiring for three-phase electricity, which is not only inconvenient for installation, but also prone to phase sequence errors. 3. Can ...

In the use of soft starters, some users often have some faulty concepts such as: 1. It is thought that whether the motor can start successfully is related to the function of the soft starter, and a good brand or even a foreign brand should be selected under heavy load. 2. When the motor is not ...

1. The output power of Delixi voltage regulator is the maximum power Basically, most of the nominal power of household appliances refers to active power, and the so-called refrigerators, air conditioners and those water pumps used in the home, etc., most of them are also rational loads that start instantaneous currents.

All large AC power blocks are transmitted and distributed at high voltage levels via a three-phase transformer. Single-phase transformers can be electrically connected to form a three-phase transformer bank in a distribution system. But the standard is to combine a single phase coil into a three-phase transformer unit on a common core ...

Delixi regulator output voltmeter keeps swinging back and forth, and sparks occur at the carbon brush, and the problem phenomenon and cause analysis 1. The contact pressure between the carbon brush and the coil plane is too small 2. The carbon brush is severely worn Delixi voltage regulator has ...

Delixi CDI-EM60 inverter has optimized open-loop vector control, V/F control, stable function, optimized function, standard configuration of common users, but also expand multi-channel I/O interface and communication function, is a delicate type of small power type. ...

Problem depiction: The data of Delixi inverter controller is unstable, and sometimes there is a deviation, how to deal with it? Solution: This is the result of severe disturbance of the controller. Often the controller ...

1. Is it possible to put the motor directly into a fixed frequency inverter without using soft start? It is possible at very low frequencies, but if the given frequency is high, the conditions for direct starting of the power supply are similar. A large starting current (6-7 times the rated current) will flow too much, due to ...

1. According to the load type, confirm the type of inverter: different load types, speed requirements and power size, and the need to choose different types of Delixi inverters. Therefore, it is necessary to understand in detail the type of motor load to be controlled to find the most suitable type. ...

On January 27, the "4th China Electrical Appliance Culture Festival and World Electrical Products Expo" was grandly opened in Liushi, Wenzhou, the capital of China's electrical appliances. More than 500 companies from home and abroad showed their faces on more than 1,400 booths. The largest Delixi exhibition hall with a booth area of more than 1,800 square meters ...

The traditional textile printing and dyeing industry is a labor-intensive industry, and the degree of automation is not high. Most of the transmissions used are not speed regulation, and most of the occasions that need speed regulation are DC motors, such as warping machines, sizing machines and many printing and dyeing equipment.

1) Rectifier The rectifier circuit of the universal inverter consists of a three-phase bridge rectifier bridge. Its function is to rectify the power frequency power supply and supply DC power to the inverter circuit and control circuit. Three-phase AC power supplies are generally required to be introduced into the input of the rectifier bridge through the absorption capacitor and varistor network.

1. Overcurrent (short circuit) Overcurrent problems are the most common in the side of various faults in the inverter. The problem is mostly due to the following problems: first, as long as the speed converter is reported when starting, it is clear that the overcurrent is very serious, and most of them are load short circuits, mechanical parts stuck, inverters...

input/output reactor for frequency conversion speed regulation; Because the inverter is often affected by the impact of inrush current and surge voltage in the process of driving the inverter motor operation governor, which will seriously damage the performance and service life of the inverter and the motor, so it is necessary to install a transmission in front of it.

1. If the two branch lines are connected, the current in the zero line flows to each other, which destroys the working current balance in the zero sequence current transformer and causes the leakage protector 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.
