1. Check whether the appearance of the inverter is in good condition, including whether the indicator light is in normal operation, whether the task control function of the operation panel is complete, and carefully observe the appearance of the inverter in operation conditions, and do the corresponding recording operations; When repairing the inverter, check whether the voltage value and current value exceed the allowable ...

(1) Insulating pads should be arranged in the maintenance channel of the battery pack. (2) It is strictly forbidden to use batteries of different manufacturers, different capacities and different models in the same system. (3) VRLA batteries do not need to be charged for the first time before use, but should be recharged. Replenish the charge ...

1. Construction preparation. Including the preparation of operating conditions (construction skills documents and detailed planning documents), construction organization planning, equipment list, data budget, and list of machined parts; 2. Cooperate with civil engineering majors to do a good job of embedding, ...

Fundamentals of magnetic flux vector manipulation The control of a three-phase asynchronous motor is much more complicated than that of a DC motor because the current, voltage, induced potential, magnetic flux, etc., of the stator and rotor are all alternating. However, the stator winding of the three-phase asynchronous motor is a symmetrical three-phase winding, which exerts a ...

1. Use the analog output port to indicate the motor frequency, when the motor frequency is 50Hz, why is the output only 16mA? Because the maximum output frequency parameter of the inverter is "TFR", the factory default value is 60Hz. So when the inverter output is 50Hz, the analog output is 16mA. At this time, only ...

1) Survey and research method. The investigation and research method is to "see", "listen", "smell", "touch" and "ask" to understand the significant faulty phenomena; After visiting the operator, understand the cause of the problem; A common way to help find faults after consulting others or consulting information ...

1. The control accuracy of the vector type is higher than that of the general-purpose type. 2. The vector type has a large output torque at low speed, which can make the motor get a larger starting torque, which is suitable for application in the occasion of heavy load starting, such as: high-power long belt, hoist, etc. If used in some of the more common fields ...

1. Electrical equipment will produce higher harmonics when it produces abnormality and deterioration, and the abnormality and deterioration of motors, loads, and inverters are used to distinguish the higher harmonics from 2 to 40 times, and the data is changed by FFT, and the analysis is made on the basis of the analysis data of long-term savings.

1. When installing and adjusting the appearance, the original status should be recorded for rehabilitation. 2. When repairing the appearance of fine instruments, if you accidentally bounce small parts away, you should first determine the direction where you can fly.

The difference between Schneider OSMC32N3D10 and OSMC32N3C10 After type comparison, one is Schneider D10A and the other is Schneider C10A. Schneider circuit breaker type D, suitable for power equipment, such as motor load, air conditioner, etc.; Schneider circuit breaker type C, suitable ...

1. Type recognition: Recognize whether the type of inverter is common with the type of inverter purchased. 2. Transportation acknowledgement: After opening the package, check whether the inverter is damaged during transportation. 3. Voltage recognition: the power supply voltage on the site should be borne by the inverter.

1) Survey and research method. The investigation and research method is to understand the obvious problem phenomena through "seeing", "listening", "smelling", "touching" and "asking"; After visiting the operator, understand the cause of the failure; A common way to help find the fault point after asking others or consulting information ...

In the process of connecting the line of the inverter, it is necessary to pay attention to the following aspects: 1. The power supply must be connected to the main circuit power terminal L1/R, L2/S, L3/T, if the power supply is connected to other terminals by mistake, the inverter will be damaged. 2. It is necessary for the grounding terminal to be well connected.

The system power is equal to the product of the inverter power and the motor power, as long as both are operating at a higher power, the system power is higher. From the power point of view, when selecting the power of the inverter, the following points should be noted: ...

1. After the UPS power supply is shut down, the output terminal is still powered, but the UPS power supply does not play a role at this time, and it is in a bypass state. 2. The power supply will not be cut off after the UPS power supply is shut down, because the UPS power supply will go bypass after the shutdown, there is still a mains power input at this time, ...

The limit short-circuit breaking ability (ICU) refers to the short-circuit current that can be turned on and broken under certain experimental parameters (voltage, short-circuit current, power factor) and through a certain experimental procedure, and after this on-off, it will no longer continue to carry its rated current. It's experiments ...

In order to ensure that the APCUPS power supply can continue to supply high-quality power to the computer even in the event of a power outage, it is important to equip the battery backup battery. When the load is not allowed to be powered, the UPS battery backup time in the communication room should be greater than the time from the mains power interruption to the rehabilitation or to the generator set is positive.
