The contact pressure between the carbon brush and the coil plane is too small 2. The carbon brush is severely worn Delixi voltage regulator has ...

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...

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 ...

The type of inverter is selected according to the type of production machinery, speed regulation range, static speed accuracy, and starting torque requirements, and it is most appropriate to decide which inverter is the most suitable to use. The so-called suitability is not only easy to use, but also economical, to meet the basic conditions and requirements of technology and production. ...

1. Frequency conversion speed regulation and energy saving. The inverter frequency conversion speed regulation and energy saving are mainly manifested in the application of fans and pumps. In order to ensure reliability in actual production, all kinds of production machinery are designed with power drives, and there is a certain margin. After turning down the motor rotation when there is no need to run at full speed in production, ...

Currently, there are many different switching regulator topologies. Some topologies are widely used, such as the classic buck converter, also known as the buck converter. However, there are also some lesser-known switch-mode DC-DC converters that include Zeta topologies. These topologies are divided into fundamental topologies ...

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. Classification of switch operation organization At present, the switches we encounter are generally divided into many types, such as oil-rich type (old model, now you can't see it at all), oil-poor type (some user stations also have it), SF6, vacuum, GIS (combined electrical appliances) and so on. These are all about the arc extinguishing medium of the switch. ...

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 ...

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 AC voltage is stepped down by the power transformer to obtain the low voltage of communication, and then the unstable DC voltage is obtained through the rectifier filter circuit, and then the voltage is regulated linearly by the low dropout ...

The so-called DC-DC is actually DC to DC voltage, of course, LDO is also a kind of DC-DC, and only LDO can only achieve step-down. The general DC-DC is mainly converted from DC to AC communication through the self-excited vibration circuit inside, so the external inductance and capacitor are required to achieve LC vibration (and LDO is only ...

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 ...

1. Check the time first, if the time of the week, hour and minute is correct, don't care. If it's not correct, you need to take care of it yourself. Conditioning is very simple, you just need to press the clock, and then adjust the week by week, the hour of conditioning, and the minutes of conditioning. ...

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.

The control of the inverter is nothing more than the fundamental logic of starting, aborting, forward rotation, rotation, and speed regulation, which fundamentally requires that the level condition is effective, rather than the rising edge is effective, so the use of button switches to control the inverter is generally required to use the self-protection of the button...

In the process of practical speed regulation, an ordinary frequency-adjustable communication power supply 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 suppression of the starting current and the acquisition of the desired torque characteristics, such as low-frequency torque characteristics.

1. What is a switching regulator? Switching regulator, English (regulatior), some people call it a regulator, a voltage regulator source. To achieve voltage regulation, it is the demand control system (negative feedback), from the automatic control theory, we know that when the voltage rises through negative feedback to reduce it, ...

Delixi CDI-EM60 series inverter is a high-performance inverter, with the following characteristics and use: Characteristic: 1. It has good stability and reliability to ensure the stability and safety of the system operation. 2. High degree, wide range of speed control, ...

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. ...

1. Trial delivery and commissioning method The first thing to find is the fault of the remaining current action maintainer itself. The detailed operation method is: first block the power supply, and then remove all the zero-sequence transformer load side leads of the remaining current action maintainer (the second and third level remaining current action maintainers will directly remove the outgoing ...
