The role of Delixi inverter

Variable-frequency drive (VFD) is an electric power control device that uses frequency conversion skills and microelectronics skills to control and communicate motors by changing the frequency of the power supply for motor operation. The inverter is mainly composed of rectifier (communication to DC), filtering, inverter (DC to ditch) ...

1. Extra limit short-circuit breaking can be used for Icu There are two types of breaking capacity targets for circuit breakers: additional limit short-circuit breaking capacity of 4U and additional operating short-circuit breaking capacity Ics. As a characteristic parameter, ICS is not only a brief consideration of the breaking ability of the circuit breaker, but also a breaking purpose.

Delixi's three-phase circuit breaker is generally divided into three types, namely 3P, 3P+N and 4P. (1) Differences: 3P: Pure three-phase electrical equipment only uses three wirings, and in the case of no single-phase load, it trips when it is short circuited to ground or phase; Otherwise, when a one-phase N-line load is generated, the N-line is disconnected ...

E100 series products are a standard inverter with optimized open-loop vector control, V/F control, stable performance, rich functions, optimized structural design, exquisite appearance, and high cost performance. Technical features: ...

All large AC power blocks are connected by a three-phase transformer for transmission and distribution at high voltage levels. 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 ...

On March 12, Delixi Electric partner Qingdao Hengtong Ruide received an order, continued to deploy a batch of components to be shipped to Laixi cabin hospital, Delixi Electric strategic cooperation plant Qingdao Fengtai Electric overnight deployment, 24 hours smoothly completed handover, escort for Qingdao war epidemic. ...

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 ...

1. There is a problem with an inverter, it cannot operate and the LED shows "UV" (abbreviation of under voltage), which clarifies that the alarm in the book is under voltage of the DC bus. Because the power supply of the control loop of this type of inverter is not taken from the DC bus, but from the AC input through the transformer alone.

It shows that the voltage regulator base is not voltage corrected, and the voltage regulator in this situation is like a transformer, the higher the input voltage, the higher the output voltage, the input decreases and the output voltage also decreases. This...

First, the process of inverter rehabilitation factory value 1. Study the manual and find the corresponding function number, or key combination. 2. Confirm that the parameters can be corrected (sometimes the inverter will set the parameter to write the protection function in order to prevent the parameters from being changed randomly, and the password must be guaranteed to enter the correction) ...

Delixi control transformer is the most used type is BK, JBK, BKC and other types, these transformers use some precautions as follows! 1. Before purchasing, estimate the total capacity of the electrical appliances used, and choose a transformer with a certain capacity to ensure that it will not burn out when it starts instantaneously.

Relay is a kind of electrical appliance that turns on or off the control circuit according to the change of external input signals, such as electrical quantity (voltage, current) or non-electrical quantity (heat, time, speed, etc.) to complete the control or maintenance mission.

1. For pure resistive loads such as incandescent lamps, resistance wires, electric furnaces and other equipment, the power of the voltage regulator should be 1.5 times the power of the load equipment - 2 times that of the load equipment, for example, if your electric furnace is about 250W, you can choose a voltage regulator with a power of 500W. 2. Rationality ...

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 ...

Quickness: It means that the maintenance device should be able to remove the short-circuit fault as soon as possible, and its purpose is to improve the stability of the system, reduce the damage to the faulty equipment and lines, reduce the scale of the fault, and improve the effect of active reclosing and active investment of standby power supply or standby equipment. Reliability: Refers to ...

Delixi inverter is a kind of inverter with both high quality and stability, it has excellent function and strong function, widely used in manufacturing, construction industry and energy conservation and environmental protection areas. Let's take a look at some of the characteristics and uses of Delixi inverter. ...

The S2 (single-phase 220V, 50/60HZ) comes standard with a built-in braking unit CDI-E102G0R4S2B 0.4KW CDI-E102G0R75S2B 0.75KW CDI-E102G1R5S2B 1.5KW CDI-E102G2R2S2B 2.2KW ...

We need to ensure that the capacity of the inverter is matched. First of all, according to the nature of the load, the correct selection of the type of inverter. When selecting the inverter, the current value of the actual motor should be used as the basis for the selection of the inverter, and the rated power of the motor can only be used as a reference. Secondly, the output of the inverter should be fully considered ...

1. Motor encoder alarm 1. The cause of the failure (1) Wrong wiring; (2) electromagnetic disturbance; (3) Encoder hardware damage caused by mechanical vibration; (4) Pollution caused by the on-site environment. 2 ...

1. When the main circuit is equipped with a total leakage maintainer, the main barrier switch, the branch barrier switch, the main circuit breaker, the branch circuit breaker or the main fuse, and the shunt fuse should also be installed. When the total leakage maintainer is a leakage circuit breaker with short-circuit, overload, and leakage maintenance functions, it can not be ...
