How to prevent power transformer burnout?
Transformer is one of the indispensable pieces of equipment in a power system. They are primarily used to convert voltage from one level to another in order to maintain the effectiveness of electrical energy transfer during transmission and distribution.
Although transformers play an important role in power systems, they are also prone to failure, the most common of which is burning out. In this article, we'll explore why transformers burn out and how to prevent it.
There can be several reasons why a power transformer burns out, the following are a few of them:
When a transformer is connected to a load circuit, if the current in that circuit exceeds the rated current of the transformer, an overload will result. This will heat up the coils in the transformer and may eventually burn them out. In addition, overloading can cause damage to the insulation in the transformer, further increasing the risk of burnout.
When a short circuit occurs in a circuit, the current increases suddenly. This will cause the current in the transformer to also increase, causing the transformer to heat up and possibly burn out.
Insulation material is a critical component in preventing current from flowing through the transformer enclosure. If the insulation material is damaged or aged, current may flow through the transformer case, causing failure or burning.
Windings in power transformers can short or open for any number of reasons, causing internal faults. This kind of failure may cause excessive current flow and burn out the transformer.
So, how to prevent the power transformer from burning out?
The rated load of the transformer should be selected according to the load current requirements of the circuit. If the load current exceeds the rated load of the transformer, the transformer will be overloaded, resulting in burning. In our daily use, we should try to avoid overloading and increase the service life of the transformer.
Periodically inspect the insulation of the transformer to ensure it is intact. If damaged, it should be replaced immediately.
The transformer should be equipped with a temperature sensor to monitor the temperature in the transformer. If the temperature exceeds the rated temperature of the transformer, measures need to be taken immediately to avoid burning out.
