Abstract
The invention discloses a switch cabinet bus grounding device, and the device comprises a pedestal with universal wheels, and a support disposed on the pedestal. The upper end of the support is provided with a cross arm, and the cross arm is provided with a clamping tool with the adjustable position. The clamping tool enables a grounding exploring tube to be fixed on the cross arm, and the grounding exploring tube is an insulating rod. The front end of the grounding exploring tube is provided with a probe, and a ground line passes through the interior of the grounding exploring tube to be connected with the probe. When the device is in use, the position of the cross arm and the position of the clamping tool for fixing the grounding exploring tube are arranged according to the positions of three-phase static contacts of different types of switch cabinets. The pedestal with the support is pushed into a handcart room of the switch cabinet, and a valve is opened. After the result that there is no voltage is determined through electricity verification, the pedestal with the support does not need to be moved out. The grounding exploring tube is quickly installed on the cross arm, and a quincuncial-type contact is reliably connected with the static contact, thereby guaranteeing the grounding reliability.
