Delixi inverter selection principle

The correct selection of the inverter is very important for the normal operation of the control system. When selecting an inverter, it is necessary to have a thorough understanding of the load characteristics driven by the inverter. In practice, people often divide production machinery into three types: constant torque load, constant power load and fan and pump load. ...

At the end of July, Delixi Electric launched a new 6 series CDW6i structural circuit breaker and a number of industrial control accessories. The new 6 series CDW6i structural circuit breaker has complete product specifications, which can provide professional customers with more choices, excellent functions, and ...

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. ...

In the design of Delixi power distribution system, the selective cooperation between the upper and lower levels of the circuit breaker must have "selectivity, rapidity and sensitivity". Selectivity is related to the cooperation of the upper and lower circuit breakers, and the speed and sensitivity are related to the maintenance of the characteristics of the appliance itself and the way the line operates ...

(1) Fault characteristics a) *** tripping may occur during operation, but if it is restarted after resetting, it often trips as soon as the speed rises. b) has a large inrush current, but most drives can already be tripped, maintenance without damage. Due to the ...

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. ...

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.), in order to complete the control or maintenance mission.

An inverter is usually a device that replaces a constant voltage and frequency with a constant voltage or frequency for a variable voltage. However, in the application, the inverter will inevitably present shortcomings, and when analyzing the shortcomings of the problem, in order to deal with the shortcomings well and quickly, ...

The main circuit is the power conversion part that supplies the voltage regulation and frequency modulation power supply to the asynchronous motor, and the main circuit of the inverter can be roughly divided into two categories: the voltage type is the inverter that converts the DC of the voltage source into a communication inverter, and the filter of the DC loop is the capacitor. The current type is to convert the DC of the current source into a communication ...

Delixi's communication regulator is divided into single-phase communication regulator and three-phase communication regulator. Among them, the types of single-phase communication regulators are mainly TND, TND3, AVR, JJW-D, DBW and other types; The types of three-phase communication regulators are mainly SJW, JJW-S, SBW and so on. ...

In the process of practical speed regulation, an ordinary AC power supply with adjustable frequency 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 pressing starting current and the desired torque characteristics, such as low-frequency torque characteristics.

Delixi inverter is a commonly used inverter, how to maintain in the event of failure? 　　Constant speed overcurrent: When the inverter is running at a constant speed, the output current exceeds the current value. Check whether the output circuit of the inverter is short-circuited. Check if the input voltage is low. Examine...

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 ...

Application of air switches (circuit breakers). Delixi air switch, also known as circuit breaker. It is a switch that actively closes as soon as the current in the circuit exceeds the additional current. Air switch is a very important electrical appliance in the low-voltage distribution network and electric traction system.

There are three types of motor inverters ●Ordinary function type. The fundamental V/F frequency conversion speed regulation function, speed regulation accuracy and torque control function requirements are not high for general use can be satisfied. ●High function type. V/F frequency conversion speed regulation with torque control function, hoist constant ...

1. Cooling fan (2-3 years) As long as the inverter is in use, the cooling fan has always been running, so the cooling fan is generally a short-service life accessory, generally after the use of the cooling fan for 2-3 years, the bearings, balls, motors, etc. of the fan are seriously worn, and they need to be replaced.

1.AC/DC the use of power supply Schematic diagram of the use of low-dropout linear regulators in AC/DC power supplies. In this circuit, the alternating current is stepped-down by the power transformer to obtain the AC low voltage, and then through the rectifier filter circuit to obtain the unstable DC voltage, and then through the low dropout linear voltage regulation.

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 ...

1. It can reduce the impact on the power grid, and there will be no problem of excessive peak-to-valley difference. 2. It can speed up the controllable function, and then speed up the slipping according to the needs of the user; 3. The abort mode of the motor and equipment is controllable, ...

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.
