TRANSFORMER VAULT SYSTEM HAVING WATER LEVEL SENSING APPARATUS

摘要

A power receiving and a transforming system are provided to prevent an erroneous operation by replacing an electronic water level senor with a mechanical water level sensor. A power receiving and a transforming system includes a water level sensor(400) and a compressed air supply unit. A water level sensor senses the water level of the water flowed into the power receiving and a transforming system while including a compressed air exhaust line(420), a float(430), and an on/off valve(450). The float is moved by the buoyancy of water. If the float is lower than a reference level, the valve block the air exhaust line, and it is higher than the reference level, the valve is opened.
