MECHANICAL INTERLOCK APPARATUS, PANEL ASSEMBLY AND OPERATION ASSEMBLY FOR ELECTRICAL DEVICE AND ELECTRICAL DEVICE

摘要

The present disclosure relates to a mechanical interlock apparatus, a panel assembly and an operation assembly for electrical devices and the electrical devices. The mechanical interlock apparatus comprises first interlocking lever and second interlocking lever which are arranged to be spaced apart by a predetermined distance and coupled to a first electrical device and a second electrical device, respectively; and a first and second pivoting members arranged to be connected with each other and operable to rotate about the axis in the same direction; a first and second driving pins respectively arranged on the first and second pivoting members and located on both sides of the axis, the first and second driving pins being coupled to the first and second interlocking levers, respectively, such that the first and second interlocking levers respectively move in opposite directions in response to the first electrical device being closed, to prevent the second electrical device from being closed. It is possible to, through the mechanical interlock apparatus, the panel assembly and the operation assembly of the present disclosure, provide an interlock between the electrical devices and installation of the panel assembly and the operation assembly with a structure that is simple and easy to assemble the electrical devices.
