A device for preventing
signal points of a medium-
voltage switch cabinet and a grounding handcart from being touched by mistake comprises the medium-
voltage switch cabinet and the grounding handcart, a handcart baffle used for installing a microswitch support and an
aviation socket support used for installing an
aviation socket are arranged on the top of a handcart chamber of the medium-
voltage switch cabinet, and a plurality of microswitches are arranged on the microswitch support. Each microswitch is respectively connected with an output terminal strip of the medium-voltage switch cabinet and is used for transmitting
tripping signals, the position height of the microswitches is higher than the height of the grounding handcart, the upper end face of the grounding handcart is provided with a microswitch pressing plate, and the microswitch pressing plate is used for pressing the microswitches to enable the
tripping signals to be communicated. The grounding handcart is provided with an
aviation plug, and the aviation plug is provided with an
insertion core which is used for being connected with a power
signal and is matched with the aviation socket to transmit the power
signal. The problems of limited
system functions caused by few signal transmission points of the medium-voltage switch cabinet and
signal interference between a grounding handcart and the medium-voltage switch cabinet during maintenance and repair of a power
distribution system are solved.
