A hanger of a transformer installed in a telegraph pole is provided to automatically melt snow near a fixing block, a hanger band, and a hanger bracket by operating a heater according to a sensing signal of a snowfall sensing device. A hanger band(10) is installed in a center part of a telegraph pole(2). In the hanger band, a space part(11) is formed behind a surface adhered in a hanger bracket. The hanger bracket(20) is installed in a transformer(1). A screw axis(30) penetrates the hanger bracket, and is inserted in an insertion hole(12) of the hanger band. A driving device(40) rotates the screw axis. A fixing block(50) is inserted in the space part of the hanger band. A heater(80) is installed on a rear side of the fixing block. A control part is connected to the driving device and the heater. A snowfall sensing device(70) includes a housing, a lift bar, a supporting pole, a connection rod, a spring, a sensing switch, and a wrinkled pipe. If the snow piles up on the lift bar, the sensing switch outputs a sensing signal. A control switch is installed in a side of the hanger bracket, and controls the heater and the driving device. |
