The scene of the explosion, the remaining "shell"
With the bullet, what is the effect?
Looking at the image above, we can see the physical damage caused by a projectile. The impact creates a visible crater and leaves behind fragments that reveal the internal structure of the object. This kind of damage is often seen in high-velocity impacts or explosions.
Explosion site 1: Tantalum capacitor reverse connection
This image shows the aftermath of an explosion caused by a tantalum capacitor being connected in reverse. Capacitors are designed to handle voltage in one direction, and when they are reversed, it can lead to catastrophic failure. The result is a sudden release of energy, which causes the capacitor to rupture or even explode.
Explosion site 2: Aluminum electrolytic capacitor, super pressure explosion
Here we see another type of capacitor failure — an aluminum electrolytic capacitor that has exploded due to excessive pressure. These capacitors are commonly used in power supplies and can fail if overvoltage or overheating occurs. The explosion can be quite violent, with shrapnel and chemical leakage posing serious risks.
Explosion Scene 3: Super Capacitor Short Circuit
A short circuit in a super capacitor can lead to rapid energy discharge and thermal runaway. In this case, the capacitor ruptured, causing visible damage and possibly releasing harmful gases. Super capacitors are known for their high energy density, so when something goes wrong, the consequences can be severe.
Explosion site 4: High voltage discharge
High voltage discharges can cause significant damage, not only to the components but also to surrounding materials. This image shows the aftermath of a high-voltage arc or spark that led to an explosion. Such events can occur in power systems, especially if insulation fails or there is a fault in the circuit.
Understanding these failure modes is crucial for engineers and technicians who work with electrical systems. Proper design, testing, and safety measures can help prevent such incidents and ensure the reliability and safety of electronic devices.
