Capacitor electricity taking device of column box type switch

The utility model aims to provide a capacitance electricity taking device of a column box type switch, which comprises a component A and a component B. The component B is a cavity, the component A is nested in the cavity of the component B. The component A comprises an electricity taking capacitor, a voltage sensor used for detecting the voltage of the electricity taking capacitor, and a filling medium. The power taking capacitor and the voltage sensor are injected into the filling medium, and the filling medium is insulated; the component A is insulated, the component B is insulated, the power-taking wire is used for taking power, the incoming end of the power-taking wire is connected with the power-taking capacitor, and the leading-out end of the power-taking wire is led out through the filling medium and the component B in sequence, and the capacitor lower outgoing line and the sensor lower outgoing line are led out from the lower end through the filling medium and the component B respectively. The capacit
