Delixi circuit breaker protection features

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 ...

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.

In most large electrical systems, generators and power transformers are the two most expensive pieces of equipment. In addition to the capital cost of purchase, the continuity and reliable operation of these two key equipment systems are also the most critical. For example, the test ...

The high-voltage circuit breaker (or high-voltage switch) is the primary power control equipment of the substation, which has arc extinguishing characteristics. When the system is in normal operation, it can intercept and connect the no-load and load currents of lines and various electrical equipment. When there is a problem in the system, it can quickly block the fault with the cooperation of relay maintenance.

Delixi built-in bypass soft starter CDRA-K3 series is a set of soft start, soft parking and multi-functional protection in one of the motor control equipment. Realize a smooth starter motor without impact during the entire starting process. CDRA-K3 series has built-in bypass contactor and control power supply.

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 ...

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.

Varieties of circuit breaker accessories It is divided into two categories: in-flight accessories and out-of-flight accessories. The accessories in the machine are the subordinate equipment of the equipment inside the circuit breaker, including four types: shunt tripper, undervoltage tripper, auxiliary switch and alarm switch. Normally the in-flight accessories have to be uncovered with the device, but now ...

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 ...

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.

There are many kinds of manufacturers and brands of electrical equipment and sales of electrical equipment on the market, we must choose the authentic brand of Delixi Electric when buying, and we must buy from regular dealers to avoid buying fakes. Everyone calls the electric tiger because electricity will form poles when it is not used properly.

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. 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.

1. If the fuse is burned out, please approve the load equipment as soon as possible, make repairs in time, and restore power; 2. If you use a fixed amount of fuse, please use a regular line, and do not match it at will, so as not to cause ...

First of all, Delixi inverter has a very high control accuracy. It uses advanced electronic skills and digital control skills, and can control the speed, torque, and current of the motor with a high degree of control. Together, the controller of Delixi inverter also has a high overload capacity and strong ...

The CDW3 series frame circuit breakers are rated from 400A to 6300A and 415V/690V AC for extreme environmental conditions of 50 Hz AC and -40°C to 70°C. It is mainly used in the distribution network, distributing electric energy, protecting lines and power supply equipment from ...

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.

CDB1 miniature circuit breaker is a kind of current-limiting high-breaking miniature circuit breaker with double protection of overload and short circuit, which is suitable for AC 50Hz, rated voltage 400V and below, rated current 63A and below circuits, as line overload and short circuit protection, can also be used under normal circumstances.

LDO, or low dropout regulator, is a low-dropout linear regulator that uses a transistor or field-effect transistor (FET) operating in its saturation region to subtract the excess voltage from the input voltage used to generate a conditioned output voltage. ...

According to the controlled target and operating parameters such as voltage, current, power, frequency and operating system, the additional parameters of the contactor are determined. 1) The coil voltage of the contactor should generally be lower, so that the insulation requirements of the contactor can be reduced, and it is safer to use. But for the sake of the party ...
