External Factors at Play: Understanding and Preventing Accumulator Failures

When exploring the external fault factors of accumulators (also known as accumulators, capacitors, etc.), we need to understand how these external factors affect the normal operation of accumulators and take corresponding measures to prevent the occurrence of faults. The following are suggestions for understanding external factors and preventing accumulator failures:
1、 Understanding external factors

  1. Environmental factors
    Temperature fluctuations: Extreme changes in ambient temperature can affect the performance of materials inside the accumulator, such as the stability and insulation performance of dielectric materials. Excessive temperature may accelerate material aging, while too low temperature may cause the material to become brittle.
    Humidity and moisture: Prolonged exposure to humid environments can lead to corrosion of internal components in accumulators, resulting in short circuits or decreased performance.
    Dust and pollutants: Dust and pollutants in the air may adhere to the surface or enter the interior of the accumulator, affecting heat dissipation and insulation performance.
  2. Physical factors
    Vibration and shock: In industrial or transportation processes, accumulators may be subjected to mechanical vibration and shock, causing internal components to loosen, break, or have poor contact.
    External force action: Improper installation, handling, or use may also result in damage to the accumulator due to external forces such as impacts.
  3. Electrical factors
    Voltage anomaly: Overvoltage or undervoltage conditions may cause the accumulator to withstand voltage beyond its design range, leading to internal component breakdown or accelerated aging.
    Electromagnetic interference (EMI): Nearby electrical equipment or electromagnetic fields may generate electromagnetic interference, affecting the signal transmission and stability of accumulators.
    2、 Measures to prevent accumulator failures
  4. Environmental control
    Temperature control: Ensure that the accumulator operates within the manufacturer’s recommended temperature range and consider using a temperature control system to stabilize the working environment temperature.
    Humidity control: Install the accumulator in a dry and well ventilated environment, using a waterproof and moisture-proof casing or packaging to protect it from the effects of moisture.
    Cleaning and maintenance: Regularly clean the surface and interior of the accumulator to prevent the accumulation of dust and pollutants.
  5. Physical protection
    Shock absorption measures: During transportation and installation, appropriate shock absorption materials and devices should be used to reduce the impact of vibration and impact on the accumulator.
    Stable installation: Ensure that the accumulator is securely installed to avoid unnecessary movement or impact during use.
  6. Electrical protection
    Voltage stability: Install voltage stabilizers and protective devices to prevent voltage fluctuations from causing damage to the accumulator.
    Electromagnetic shielding: Using electromagnetic shielding materials or techniques to protect accumulators from electromagnetic interference.
  7. Regular inspection and maintenance
    Performance monitoring: Regularly check the performance parameters of the accumulator, such as capacitance value, leakage current, etc., to ensure that it is in a normal state.
    Preventive maintenance: Develop a preventive maintenance plan based on the manufacturer’s recommendations and maintenance manual, including cleaning, tightening, and replacing aging components.
  8. Operation training
    Personnel training: Provide training to personnel operating and maintaining accumulators to understand their working principles, operating procedures, and maintenance requirements.
    In summary, by understanding the factors causing external faults in the accumulator and taking corresponding preventive measures, we can effectively reduce the occurrence rate of accumulator faults and improve their reliability and stability in operation.
