Delixi CDM molded case circuit breaker upgrade

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.

Three-phase communication servo motors are widely used, but after long-term operation, various problems will occur. Timely identification of the cause of the fault and corresponding treatment is an important task to prevent the spread of the fault and ensure the normal operation of the equipment. One...

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. Avoid water and air entering the transformer (1) The transformer should be protected from water ingress and moisture during operation, and it is necessary to seal well the cap of the casing item, the top of the storage phase, the bushing pipe and its connecting pipes. If necessary, a leak detection test should be carried out, and if the insulation has been found to be damp, it should be adopted in time.

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.

CDB1 miniature circuit breaker is a kind of current-limiting high-breaking miniature circuit breaker with double protection of overload and short circuit, which is suitable for AC 50Hz, rated voltage 400V and below, rated current 63A and below circuits, as line overload and short circuit protection, can also be used under normal circumstances.

1. Check and tighten all terminals to prevent serious heating caused by loosening. 2. Conduct a comprehensive view of the input (including output) terminal, rectifier module, inverter module, DC capacitor and fast-melting devices, and the parameters ...

Since it is used as a low dropout voltage regulator, the first feature is the extremely low input and output voltage difference, and secondly, it also has stable voltage output, low noise, small ripple, small size, and simple peripheral circuits. If an LDO regulator is used when planning the circuit, the general requirement is at least ...

1. Single-phase circuit single-phase power supply - power supply with a single AC electromotive force. The fundamental power supply method for civil electricity. Single-phase load – A load that is powered by a single-phase power supply. Household appliances such as lights, televisions, and electric fans are generally single-phase loads. The accounting method is as follows: a. When negative ...

1. How to disassemble the voltage regulator Generally, there are screws on the shell of the voltage regulator, please disconnect the power supply first, and then remove all the screws on both sides to take off the shell. After the regulator shell is disassembled, the circuit, copper coil, carbon brush, etc. inside will be revealed.

When the VFD is viewed regularly, the power supply should be blocked, the operation of the VFD should be stopped, and the cover of the VFD should be removed. The first thing is to check the places that cannot be seen without downtime, or the places where it is difficult to find problems on a daily basis, as well as the inspection and adjustment of electrical characteristics. After blocking the VFD power supply, the main power ...

In most large electrical systems, generators and power transformers are the two most expensive pieces of equipment. In addition to the capital cost of purchase, the continuity and reliable operation of these two key equipment systems are also the most critical. For example, the test ...

01 "O" ring spell In addition to the oil seal problem of the reducer itself, the robot manufacturer will also have an impact on the planning and installation of the reducer components, due to the sealing of the reducer, in addition to the oil seal, there are also O-rings. O-rings are a very common type of product sealing planning.

CDB1 miniature circuit breaker is a current-limiting high-breaking miniature circuit breaker with overload and short-circuit two-layer maintenance, which is suitable for communicating 50Hz, additional voltage 400V and below, and additional current 63A and below circuits.

1. Shielded wires should be used for signal lines and control lines, which is beneficial to avoid disturbance. When the line is long, for example the distance jumps 100m, the conductor cross-section should be enlarged. The signal line and the control line should not be placed in the same cable trench or tray with the power line, so as not to disturb each other, it is best to place it through the pipe, ...

Delixi solid state relay and Delixi communication contactor are more used products, so what are the advantages of solid state relay relative to communication contactor, how should we choose when we can choose? 1. First of all, the solid ...

Press the undo function key first, then press and hold the school time function key, then adjust the time and date to the current moment, press the punctual function key again, adjust the time that needs to be closed and open to the specified value, if you need to set multiple groups, then press the punctual function key to set, without multiple groups ...

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.

　　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.

1. Superior performance The new vector control algorithm is adopted, and the starting cabinet is large, the torque response is fast, and the control accuracy is high, which further improves the operation efficiency of the motor. 2. Powerful function and low cost of use Built-in large number of ...
