Detailed Introduction of GGJ Low-voltage Capacitor Cabinets

2 天之前· GGJ low-voltage capacitor cabinets mainly achieve reactive power compensation by connecting capacitor banks in parallel in the low-voltage power distribution system. When inductive loads in the power grid, such as motors and transformers, are operating, they consume a large amount of reactive power, resulting in a decrease in the power factor

6 FAQs about [The fuse of the capacitor in the low voltage cabinet exploded]

What causes a capacitor to explode?

Reverse Polarity is the most common cause for a capacitor to explode. This occurs when polarised components, like electrolytic capacitors, are wired incorrectly in a circuit.

What causes a capacitor to fail?

The cause for a capacitor's failure was not indicated in the investigation. Dust and the salt atmosphere could have contributed to the failure.

What happens when a capacitor's voltage is exceeded?

Exceeding the voltage limits of a capacitor can cause the dielectric to fail which results in large currents flowing. This can lead to a short circuit or even an explosion.

What happens when a capacitor's dielectric fails?

Exceeding the voltage limits can cause the dielectric to fail, which results in large currents flowing. These large currents cause large amounts of heat and thus destroy the internal structure of a capacitor.

What happens if an electrolytic capacitor is wired incorrectly?

An electrolytic capacitor is a polarised component that has a positive and negative terminal which means it needs to be wired the right way in a circuit. If it is wired incorrectly, it can cause the capacitor to explode.

What happens if you wire a capacitor the wrong way?

If you wire a capacitor the wrong way in a circuit, the positive terminal gets connected to negative, and the negative terminal gets connected to positive. This is known as reversing the polarity of a capacitor. If you apply a voltage for a very short amount of time, it shouldn’t be much of a problem.
