Claims

[Scope of utility model registration request]

In an instrument transformer device installed in a closed switchboard, one end thereof is coupled to the frame of the switchboard by a hinge, and a rotating handle is provided at the end opposite to the one end, and the handle allows the hinge to rotate. An instrument transformer is fixed to the back side of a hinged panel configured to be engaged with or released from the switchboard using the fulcrum as a fulcrum, and the panel is engaged with or released from the switchboard. At the same time, a connecting contact attached to the potential transformer is connected to or released from a connecting contact of an electric circuit fixed to the switchboard. Potential transformer equipment in switchboards.
