APPARATUS FOR DETECTING INTERNAL DISORDER OF GROUND TYPE ELECTRIC TRANSFORMER

摘要

PURPOSE: An apparatus for detecting internal disorder of a ground type electric transformer is provided to easily detect abnormal pressure inside the ground type electric transformer by attaching a detection device to the electric transformer. CONSTITUTION: A deformation unit is installed in a vent formed on a transformer tank of a ground type electric transformer. A proximity sensor(100) is installed on the deformation unit. An alarm(300) generates an emergency signal according to sensing signals of the proximity sensor. A power source runs the proximity sensor and the alarm. The power source comprises a solar cell panel(210) and a storage battery(220) connected to the solar cell panel.
