PROBLEM TO BE SOLVED: To provide a voltage measuring device capable of reducing labor burden of an operator and securing a safety of the operator.SOLUTION: A voltage measuring device 1 is constituted by including a box body 3 provided inside an electric pole 2 and a voltmeter 4 accommodated inside the box body 3. The box body 3 has a hollow-shaped main body and a door to shut off the inside and the outside of the main body. The voltmeter 4 is connected to a low voltage electric line 5b installed in the electric pole 2 by a connection line 6. The electric pole 2 is formed with a guide hole, on a top end side, for guiding the connection line 6 into the inside and a mounting hole for mounting the box body 3 on a base end side. An operator opens the door of the box body 3, and can perform a voltage operation only by performing a connection operation necessary for the measurement. |
