Delixi voltage regulator fault phenomenon and solution

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.

There are many types of three-phase communication regulators in Delixi, the most commonly used ones are SJW and SBW, etc., so we need to pay attention to the process of application: First of all, it must be operated correctly according to the instructions of the voltage regulator.

First, the process of inverter rehabilitation factory value 1. Study the manual and find the corresponding function number, or key combination. 2. Confirm that the parameters can be corrected (sometimes the inverter will set the parameter to write the protection function in order to prevent the parameters from being changed randomly, and the password must be guaranteed to enter the correction) ...

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. For pure resistive loads such as incandescent lamps, resistance wires, electric furnaces and other equipment, the power of the voltage regulator should be 1.5 times the power of the load equipment - 2 times that of the load equipment, for example, if your electric furnace is about 250W, you can choose a voltage regulator with a power of 500W. 2. Rationality ...

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 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. ...

Delixi switch socket real and false distinction 1. Appearance The shape of genuine Delixi switches is relatively fashionable, looks beautiful, neat appearance, and other impact resistance functions are relatively strong, not easy to crack or turn yellow. Whereas...

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.

1. The inverter runs with the motor at no load 1. To set the power and number of poles of the motor, the operating current of the inverter should be considered. 2. Set the maximum output frequency, fundamental frequency, and torque characteristics of the inverter. The general-purpose inverter is equipped with a number of VPf curves for users to choose.

　　Seriously affect the normal operation of the inverter. The core components of the inverter are IGBT power semiconductor switching components. When they are working properly, they generate a lot of heat. If there is no fan forced cooling, the sensing head will immediately detect (IGBT) overheating (IGBT) and send it ...

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 ...

Quickness: It means that the maintenance device should be able to remove the short-circuit fault as soon as possible, and its purpose is to improve the stability of the system, reduce the damage to the faulty equipment and lines, reduce the scale of the fault, and improve the effect of active reclosing and active investment of standby power supply or standby equipment. Reliability: Refers to ...

There are also several types of quasi-sine waves, ranging from square waves, which are almost indistinguishable from square waves, to rounded trapezoidal waves, which are relatively close to sine waves. We're only going to talk about square waves, which are the waveforms that most commercially available high-frequency regulators can supply today. ...

The output of Delixi inverter controller does not match the operating frequency, and the analog output of the inverter is abnormal? Solution: First, you should confirm what hardware is wrong. Make the controller enter the manual debugging state, and use the universal ...

1. If the two branch lines are connected, the current in the zero line flows to each other, which destroys the working current balance in the zero sequence current transformer and causes the leakage protector to malfunction. If you want to use the neutral line of the power branch line as the neutral line of the lighting branch line nearby, it will cause the leakage of the power branch line.

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. Although the air switch is a type of circuit breaker, it is a switch that will automatically disconnect as long as the current in the circuit exceeds the rated current. However, air switches are used in low-voltage distribution networks and electric traction systems, mostly on the low-voltage side. Widely used in the home, such as general household switches ...

1. Conductors 1. Color High-quality copper is called "red copper" or "red copper" – as the name suggests, this copper is reddish, purple, and dark red in color. The worse the copper, the lighter the color and the more yellow it is, which is called "brass". 2. Thickness ...

1. Voltage circuit breaker problem The contact is overheated, you can smell the power distribution control cabinet, by checking that the moving contact is not completely inserted into the static contact, and the contact pressure is not enough, resulting in a decrease in the switching capacity, causing the contact to overheat. At this moment, it is necessary to adjust the operating organization so that the moving contact is completely inserted into the static contact ...
