Why should substations prevent small animals? What are the specific measures?

The small animals mentioned here refer to mice, snakes, cats, birds and so on. In the power system, there have been many accidents caused by small animals entering the high-voltage distribution room or climbing on the electrical equipment, resulting in phase-to-phase short circuit and grounding short circuit faults. Therefore, to ensure the safe operation of substation equipment, substations must prevent small animals.

The measures that can be taken to prevent small animals in substation are: installing baffles and small-eye barbed wire on doors and windows; Plug the holes in time when the relevant construction in the substation is completed or interrupted; Placing rodenticide erbium; Regularly check the facilities for preventing small animals, and once traces of small animals are found, they should be thoroughly traced; No food is stored or littered in the substation to avoid attracting small animals.
