Delixi inverter CDI-E180 series of introduction

Delixi 3P air switch, additional current 630A, additional voltage 380V. The Icu=Ics=70kA of this circuit breaker. When the short-circuit current reaches 70kA, can the circuit breaker still be used? Assuming it works, the ICU is now at its limit, which is paradoxical. Assuming it can't be used, Ics is 70KA, clarifying ...

The fuses should be installed on the lines of each phase. It is strictly forbidden to install fuses on the neutral line of the two-phase three-wire or three-phase four-wire circuit. Fuses are mainly used for short-circuit maintenance. When the fuse is used for blocking purposes, the fuse must be installed.

If the zero line of Delixi's air switch is reversed to the front, there is not much obstacle to the 2P circuit breaker and 2P leakage circuit breaker. The only effect is that it looks irregular, and you need to find the zero line from scratch when repairing, which brings a little inconvenience. ...

Typically, every electrical device or device is designed for a wide range of input voltages. Depending on the sensitivity, the operating scale of the device is constrained to a specific value, for example, some devices can tolerate ±10% of the additional voltage, while others can tolerate ±5% or less. ...

1. The instantaneous high temperature in the grinding process will make the surface of the workpiece reach a molten state, and the steel surface will react with the oxygen in the air chemically, which will form a very thin (20-30nm) iron oxide film.

(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 ...

1. The problem current reaches or exceeds the set operating current value. 2. The problem current continues to arrive at the set time of action. Therefore, it is necessary to ensure that the Delixi circuit breaker will not trip beyond its liquid level. Current setting ...

Delixi high-precision fully active AC voltage regulator uses linear integrated circuits to form a control system, controls the servo motor, drives the contact voltage regulator to actively regulate the voltage, and is equipped with delay, overvoltage, undervoltage and overcurrent maintenance functions. The product has high efficiency, the same input and output voltage waveforms, and the output ...

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 voltage, current) or non-electrical quantity (heat, time, speed, etc.) to complete the control or maintenance mission.

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

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 ...

CDHR16 series strip fuse disconnector with an additional frequency of 50Hz, an additional operating voltage of 500/690V, and an additional operating current of 630A, which is mainly suitable for power distribution circuits and motor circuits with high short-circuit current, is used as a power switch, isolation switch, and as AC circuit short-circuit protection.

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.

Since its creation in the 1970s, which began as a patent for Zap Trap under the pleasant name, surge maintenance equipment (SPD) has become essential in many lightning protection systems (LPS). Surge maintainers are now used in electrical installations to avoid transient overpower ...

1. Poor device If the terminal posts of the leakage protector are not firmly connected during the installation, it will often lead to the heating and oxidation of the terminal post for a long time, so that the wire insulation layer will be scorched, and accompanied by the smell of ignition and rubber and plastic burning, forming an undervoltage of the line and tripping the leakage protector. ...

The selection of inverter is indeed very important, because if the selection is not suitable, it will cause a waste of time and money, and at worst it will cause production incidents and personnel damage. First of all, according to the classification and selection of the inverter 1. Inverters can be divided into general-purpose inverters and special inverters. ...

Delixi Group focuses on low-voltage power distribution and industrial automation in the field of comprehensive solutions suppliers, founded in 1984, is a collection of industrial operations, brand operations, capital operations as one of the large enterprise groups, for 18 consecutive years ranked among the top 500 Chinese enterprises. Delixi rangefinder is designed for ...

Look at the quality of the surge protector, to see whether it can complete his basic specification, relative to the surge protector of the primary specification is whether the surge operating voltage can be constrained below the required value, the surge protector must discharge the lightning current when the mission is completed, this specification must be completely completed.

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. ...

As far as miniature circuit breakers are concerned, 1P+N, 1P, and 2P are generally used as the on-off control of single-phase electrical appliances, but the functions are different. In order to facilitate the user's selection and difference, the difference of the P number of circuit breakers and the selection method are briefly analyzed. ...
