Abstract: Many enterprises will encounter a problem, said that usually electricity is relatively stable, this month's electricity may be less than last month, how much higher than last month? At this time, you should pay attention to the fine caused by the failure of the capacitor cabinet, which may cause the power factor to be too low.
In daily production, some users often have frequent start-up of large equipment (such as punching machines), resulting in instantaneous voltage reduction, which affects the normal operation of other equipment, and even burns, so why does this happen?
First of all, the operation of inductive equipment must establish a magnetic field (such as a motor), because the instantaneous start of large equipment grid needs to provide a large number of reactive current as the establishment of the magnetic field, so the voltage of the system will be greatly reduced at the start of the equipment, resulting in other equipment protection or can not operate normally or even damage.
The solution:
Since large equipment needs a large amount of reactive current at the moment of startup, it is necessary to quickly compensate the equipment at the moment of startup, so that the equipment can reduce the absorption of reactive current to the grid at the moment of startup. However, because the equipment starts relatively fast, and some equipment is frequently and quickly started, the general compensation equipment can not meet the requirements. Therefore, the JL-SVG static reactive power generator produced by our company can solve the problem of fast compensation. The response time of the SVG module produced by our company is less than 5ms, which fully meets the start-up requirements of the equipment, and ensures that the system will not affect the normal operation of other equipment due to the frequent start-up of large equipment.
