Circuit breaker refers to a switchgear that can close, carry and break the current under normal circuit conditions, and can close, carry and break the current under abnormal circuit conditions within a specified time. Circuit breakers can be used to distribute electrical energy, infrequently start asynchronous motors, and ...

1. The pressure of Delixi inverter system is unstable and simple vibration? Answer: The pressure of the system is unstable, which may be due to the following reasons: A. There is a problem with the orientation of the pressure of the pressure sensor collection system, the pressure collection point is too close to the water pump outlet, and the pipeline pressure is affected by the water outlet ...

　　The principle and operation method of Delixi inverter: 1. No-load energizing test of inverter 1. Ground the grounding terminal of the inverter. 2. Pass the power input terminal of the inverter through the leakage maintenance switch.

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 ...

Many people don't know what a surge is, surge is also known as a surge or lightning protection maintainer, the first is to maintain the household electrical equipment when it rains and thunders to avoid being damaged by lightning, and when the lightning strikes high-voltage electricity is drained to the ground through the surge maintainer, it will not directly hit the electrical equipment ...

In the project, because of the 630 A circuit breaker wiring bar in the 500 kVA box-type transformer, see the second circuit breaker and circuit breaker on the left in the figure. The temperature of this corresponding region is significantly higher than that of the other two corresponding regions, and the other two phases are also hot, and the copper bars of this phase have turned white. There is no induction Deli ...

Question: Delixi inverter control motor contactor does not start when there is no action? Solution: First check the output status of the controller reflected by the controller panel, and you can compare the 7 units on the panel described in the controller description book.

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 ...

1. Before the inverter device is in place and debugged, please tighten the components, especially the connecting bolts of the wire part, if not tightened, the connection will be heated and cause fire. 2. The on-site planning of the installation should be reasonable, and the excellent ventilation environment should be maintained. 3. The incoming and outgoing power lines of the inverter are not ...

Delixi inverter parameter check setting steps Using the keyboard to set the frequency, we can use the keyboard number direct setting and the keyboard potentiometer setting two methods, and the control method can be selected by modifying the parameter P0.01. ...

There are substantial differences between servos and inverters in terms of application intention and function. Which one to choose depends on factors such as operating mode, load conditions, price, etc. Basically, the performance of the servo is superior to that of the inverter. Therefore, when changing from an inverter to a servo, there are generally no operational problems ...

1. Appearance Genuine Delixi switch shape is more fashionable, looks elegant and beautiful, and the surface is neat, impact resistance is relatively strong, will not briefly crack or yellow. And most imitations will turn yellow after a period of use...

　　Since 2003, when he was first elected to the National People's Congress Committee, Hu Chengzhong, the current chairman of the executive president of Delixi Group, was re-elected as the National People's Congress Committee for two consecutive terms, and in 2018, he was once again elected as a representative of the people from all over the country.

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 molded case circuit breaker tripper is divided into undervoltage tripper and shunt tripper. This article explains the wiring method of the circuit breaker with sub-excitation tripper. The shunt tripper is often used as an additional accessory for the user, it is a remotely operated circuit breaker disconnection device, installed in the molded case circuit breaker, when the shunt ...

1. The use environment of regulated power supply requires good ventilation, no moisture, no corrosive gas, explosive substances, conductive dust Egypt steam, etc., and it is required to be installed in places without intense oscillation. ​ 2. The voltage regulator is used according to the function of the electrical equipment.

1. Why does the maintenance function of the inverter operate when the clutch is connected to the load? When the load is connected with a clutch, at the moment of connection, the motor changes sharply from the no-load condition to the area with a large slip rate, and the large current flowing through causes the inverter to trip over the current and cannot work. ...

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: ...

Shanghai, September 19, 2018 ---- Today, the 20th China International Industry Fair (hereinafter referred to as the "Industry Fair") officially kicked off in Shanghai. From the perspective of a new breakthrough in the integration of manufacturing and the Internet, this year's industry fair focused on showing the scientific and technological innovation of China's manufacturing profession.

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...
