Whether it is a linear regulator or a switching regulator, their daily protection must start from the following aspects: 1. Always observe whether the cooling fan and transmission organization of the voltage regulator are operating normally, check whether the input voltage and load exceed the rated scale, and deal with the abnormalities in time.

Regulator problem 1: The regulator cannot be started Reason: Whether the phase sequence of the input power cord has been changed, and the air switch in the machine is not turned on or broken. Repair methods: 1. Swap the two power supply wires arbitrarily or check whether the power supply line is correct; 2. Close or replace the switch. Voltage Regulator ...

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. The aesthetic slab adopts frameless large buttons and fluorescent grid planning, giving people a comfortable texture experience. The large-pitch flat panel is simple and useful, and is available in four colours: Funky White, Champagne Gold, Starlight Silver and Midnight Black. 2 ...

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. ...

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.

Voltage regulator fault phenomena and their corresponding solutions Input phase loss - correctly input phase A, B, C phase, should be three-phase four-wire system or five-wire system The control circuit board is not working - the control circuit board is disconnected or damaged by itself. Repair or replace Control circuit board in the state of protection ...

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. ...

On January 27, the "4th China Electrical Appliance Culture Festival and World Electrical Products Expo" was grandly opened in Liushi, Wenzhou, the capital of China's electrical appliances. More than 500 companies from home and abroad showed their faces on more than 1,400 booths. The largest Delixi exhibition hall with a booth area of more than 1,800 square meters ...

1. Install AC reactor and DC reactor. When the inverter is used in the distribution transformer capacity is greater than 500kva, and the transformer capacity is greater than 10 times of the inverter capacity, an AC reactor is installed on the input side of the inverter. And when the output voltage of the distribution transformer is unbalanced and uneven in three phases ...

The inverter is a device that can control the speed of the motor, and it completes the speed regulation by adjusting the voltage and frequency of the motor. When selecting an inverter, there are several factors to consider, including the power of the motor, the type of load, the operating environment, etc. This article will specifically introduce the selection of frequency converters ...

Voltage vf and v difference: The two have different meanings, vf on the battery represents the feedback voltage, while v represents the capacity of the battery, which is the unit of measurement of voltage. Lithium battery is a kind of battery with lithium metal or lithium alloy as the positive/negative electrode data and the use of non-aqueous electrolyte solution. ...

Leakage vacuum circuit breaker connection: When normal operation, regardless of whether the three-phase load is balanced or not, the sum of the three-phase current phasor through the main circuit of the zero-sequence current transformer is equal to zero, so there is no induced electromotive force in the secondary winding, and the leakage maintainer operates in a closed state. In the event of leakage or ...

1. The output voltmeter is constantly swinging back and forth, and sparks are generated at the carbon brush 1. The contact pressure between the carbon brush and the coil plane is too small 2. The carbon brush is severely worn 1. Clean the coil and carbon brush with a fine file or sandpaper, and then adjust the carbon brush pressure 2. Replace the carbon brushes with new ones ...
