technical field

The invention belongs to the technical field of electric power safety equipment, and relates to a protective fence, in particular to an intelligent protective fence for a box-type transformer.

Background technique

As a part of the power transmission system, the transformer plays a pivotal role in the entire power supply network. However, because the transformer itself is expensive and the metal materials used are expensive, criminals take the risk of stealing valuable parts of the transformer, which not only causes personal injury but also affects the normal operation of the power supply network. Operation brings great inconvenience to the daily life of the people.

In order to prevent the transformer from being stolen by criminals and protect the transformer from the erosion of the external environment, a protective box is usually built outside the transformer to protect the transformer. This device that builds a protective box outside the transformer is called a box-type transformer.

In order to further protect the box-type transformer, construction workers install protective fences around the box-type transformer, on the one hand to prevent animals from approaching the box-type transformer and cause danger; on the other hand, it plays a role in protecting the box-type transformer.

Even so, there are still criminals coveting the valuable parts of the transformer, and it is impossible to know the damage of the transformer in time, and there are still threats and hidden dangers to the daily life of the people.
