Uncovering the Main External Stressors That Lead to Accumulator Failures

When exploring the main external stress factors that lead to the failure of accumulators (also known as accumulators, capacitors, etc.), we need to pay attention to those external conditions that can directly affect their performance and lifespan. The following is a summary and analysis of these main external stress factors:
1、 Environmental factors

  1. Temperature fluctuations
    Description: Extreme changes in ambient temperature are an important factor affecting the performance of accumulators. Excessive or insufficient temperature can accelerate the aging of internal materials in accumulators, reduce their insulation performance, and even lead to component damage.
    Impact: Temperature fluctuations may cause thermal stress problems in accumulators, leading to uneven material expansion or contraction, resulting in cracks or damage to internal structures.
  2. Humidity and moisture
    Description: Humidity and moisture are another important environmental factor. Long term exposure to humid environments may lead to corrosion of internal components of the accumulator, resulting in short circuits or decreased performance.
    Impact: Moisture can corrode metal components, reduce the insulation performance of insulation materials, and increase the risk of leakage current.
  3. Dust and pollutants
    Description: Dust and pollutants in the air may adhere to the surface or enter the interior of the accumulator, affecting its heat dissipation and insulation performance.
    Impact: Dust and pollutants can block the heat dissipation channel, causing the accumulator to overheat; Meanwhile, they may also act as conductive media, increasing the risk of short circuits.
    2、 Physical factors
  4. Vibration and shock
    Description: In industrial or transportation processes, accumulators may be subjected to mechanical vibrations and impacts. These physical stresses may cause internal components to loosen, fracture, or have poor contact.
    Impact: Vibration and impact can accelerate wear between components, damage the structural integrity of the components, and thus affect the overall performance of the accumulator.
  5. External force action
    Description: Improper installation, handling, or external forces such as impacts during use may also cause damage to the accumulator.
    Impact: External forces may directly damage the casing or internal structure of the accumulator, leading to component damage or failure.
    3、 Electrical factors
  6. Abnormal voltage
    Description: Overvoltage or undervoltage conditions may cause the accumulator to withstand voltage beyond its design range.
    Impact: Abnormal voltage may cause breakdown or accelerated aging of internal components in the accumulator, thereby shortening its service life.
  7. Electromagnetic interference (EMI)
    Description: Nearby electrical equipment or electromagnetic fields may generate electromagnetic interference, affecting the signal transmission and stability of the accumulator.
    Impact: Electromagnetic interference can interfere with the normal working signal of the accumulator, leading to misoperation or performance degradation.
    preventive measure
    To prevent the accumulator from failing due to external stress, the following measures can be taken:
    Environmental control: Ensure that the accumulator operates under suitable environmental conditions, including stable temperature and humidity control, as well as a clean working environment.
    Physical protection: adopting appropriate shock absorption and protection measures to reduce the impact of vibration and shock on the accumulator; Meanwhile, ensure the correct installation and handling of the accumulator to avoid damage caused by external forces.
    Electrical protection: Install voltage stabilizers and protective devices to prevent voltage anomalies from causing damage to the accumulator; Meanwhile, electromagnetic shielding technology is adopted to reduce the impact of electromagnetic interference.
    Regular inspection and maintenance: Regularly inspect and maintain the accumulator, including cleaning, tightening, replacing aging components, etc., to ensure that it is in good working condition.
    In summary, by identifying and controlling these major external stress factors, we can effectively reduce the risk of accumulator failure and improve its reliability and stability in operation.
