Delixi voltage regulator fault phenomenon and analysis

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 ...

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 ...

The control of the inverter is nothing more than the basic logic of starting, aborting, forward rotation, rotation, and speed regulation, which basically requires that the level condition is useful, not the rising margin is useful, so the use of button switches to control the inverter is generally required to use the button in the form of self-protection ...

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.

All large AC power blocks are transmitted and distributed at high voltage levels via a three-phase transformer. 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 ...

1. What should I do if the indicator light is on and when it is dark Generally, the reason for this situation is that the line contact is poor or the screws of the terminal are not tightened, we should check the condition of the line, connect the power cord and tighten the screws, and press the wire. ...

Delixi is one of the world's top 500 enterprises, the quality of its switches is excellent, the layout is reasonable, and is deeply liked by the majority of customers. Founded in 1984, China Delixi Holding Group Co., Ltd. is a large-scale group integrating capital operation, brand operation and industrial operation, with a registered capital of 15 ...

Delixi circuit breakers and contactors are used to make and break circuits. The rated current of the circuit breaker is generally greater than that of the contactor (the maximum current medium voltage contactor is 630 A); The circuit breaker has excellent short-circuit current breaking capability (now the maximum capacity of the medium voltage system is 80KA), and the contactor needs to cooperate with the fuse...

First of all, when the transformer is faulty, we must cut off the power supply of the transformer through abnormal methods for the first time, and many major electrical fires and electric shocks are caused by the main gate is not closed. Now let's take a look at what to do. ...

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.

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.

The circuit breaker has arc extinguishing equipment, so the circuit breaker can be operated with load, not only the load current, but also the fault (short circuit) current; The circuit breaker has a good package form, so simply observing the circuit breaker cannot intuitively determine whether it is in the closed or disconnected position. Isolate ...

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.

1. The socket quality is low quality First of all, we should check whether the socket is a miscellaneous and inferior product, the copper clamping force in the defective socket is not good, resulting in poor contact between the socket and the plug, and the socket and plug will heat up after a long time of electrical use. So be sure not to buy cheap miscellaneous ...

Requirements for electrical barriers. Between A and B circuits, signal transmission is required, but because of the disparity between the power supply levels of the two circuits, one is hundreds of volts, and the other is only a few volts; Two very different power supply systems, unable to share the power supply; ...

Delixi's communication contactor is widely used in industrial electrical, contactor as a kind of electromagnetic switch, its interior is mainly composed of the main and auxiliary contacts and electromagnetic coils, static cores and other parts of the control line connection and breaking. ​ ...

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. ...

Thermal accounting requires information such as power loss, thermal resistance of the package, and ambient temperature. The power loss is calculated in the same way as the efficiency accounting, which is simply the value of the difference between the output input voltage and the input current. The thermal resistance should have a technical standard documented, and if it is not, it is necessary to ask the manufacturer. Basically...

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.
