Reactive power compensation capacitor is a kind of reactive power compensation device commonly used in power systems, and is widely used today. When the compensation capacitor does not reach the rated voltage value, it may have an impact on the power system and related equipment.
In today's article, Xiaoku will discuss this problem, come and find out!
1.The power factor decreases
The main function of the reactive power compensation capacitor is to provide reactive power, thereby reducing the total power factor of the system.
When the capacitor cannot reach the rated voltage, its capacitance value is affected, correspondinglyThe ability to compensate for reactive power is also reduced。This will lead to systematicThe power factor decreasesto reduce the efficiency and stability of the system.
2.The current is too high
When the reactive power compensation capacitor cannot reach the rated voltage, in order to maintain a certain reactive power compensation,The current will increase。Excessive current will lead to electrical equipment such as capacitors, capacitor switches, etcSubjected to excessive loads,And then it goesThe device is overheating, linesLoss increases、Power supply equipmentOverloadand so on.
3.The capacitor itself is faulty
If the capacitor does not reach the rated voltage value, it means itOperates at excessively high voltages, which may cause capacitorsThe internal structure is damaged, which will further amplify the impact of the failure, causing the capacitor to fail and cannot be used continuously.
4.Voltage fluctuations
When the compensation capacitor cannot reach the rated voltage value, it may resultFluctuations in reactive power,This in turn causes fluctuations in voltage. Fluctuations in voltage may cause electrical equipmentAbnormal work, so it should be avoided as much as possible.
5.Safety hazards
Reactive power compensation capacitors can easily occur if they are operated in an excessively high voltage environmentBreakdown failure, which may cause arcing phenomena and induce capacitanceOn fire, **Failures, if not dealt with in a timely manner, are more likely to resultFire and safety risks
To sum up, it is very important to ensure that the compensation capacitor can reach the rated voltage value, which can not only ensure the safe and stable operation of various power equipment, but also effectively reduce the risk of capacitor failure and ensure the final effect of reactive power compensation.
