The electrolyte is subjected to heavy current flow as a result. Significant current levels will produce significant heat levels. This intense heat will turn the water into gas, which will build up pressure inside the capacitor and eventually cause it to blow up. The various factors that can cause capacitor explosion are given below.
Yes, capacitor explosions have the potential to endanger lives and damage property. An explosion can cause physical injury and equipment damage due to the release of energy and debris. When working with capacitors, it’s crucial to adhere to safety procedures and take the proper precautions.
When a strong inrush current surge occurs, if the inverter protection is not timely, the IGBTs of multiple power units will be burned and exploded at the same time. Previous: Dual voltage rectifier circuit design, IGBT module is suitable for rectifier circuit?
The large explosion incidents, in which battery system enclosures are damaged, are due to the deflagration of accumulated flammable gases generated during cell thermal runaways within one or more modules. Smaller explosions are often due to energetic arc flashes within modules or rack electrical protection enclosures.
However, IGBT modules often explode. Below, Xiaobian will analyze the case in detail. First, the IGBT explosion: For some reasons, the loss of the module is very large, the heat can not be dissipated, resulting in extremely high internal temperature, generating gas, breaking the shell, this is the so-called IGBT explosion.
Comparing its predecessors, the electrolytic capacitor is the kind that is most likely to result in a spectacle when it explodes. Other capacitors will burn, crack, pop, or smoke instead of exploding. The oxide layer deteriorates when an electrolytic capacitor fails. The electrolyte is subjected to heavy current flow as a result.
