Abstract

The invention discloses a connecting structure, a deep well type vertical grounding electrode and an assembling method thereof, and relates to the technical field of grounding in direct current transmission engineering. The object of the invention is to solve the problem of how to increase the welding strength and reliability between the feed steel pipe and the flow guide cable in the deep well type vertical grounding electrode. The connecting structure of the invention comprises a lantern ring and a connecting lug fixed on the outer wall of the lantern ring, wherein the lantern ring is used for being sleeved with a feed steel pipe in a matching manner, a side wall of the lantern ring is provided with a welding port, which is communicated with the inner space of the lantern ring, and the connecting lug is used for being welded with a conductor in a flow guide cable. The connecting structure of the invention is used for connecting the feed steel pipe and the flow guide cable.

Description

technical field [0001] The invention relates to the technical field of grounding in direct current transmission projects, in particular to a connection structure, a deep well type vertical grounding electrode and an assembly method thereof. Background technique [0002] At present, in the field of grounding technology of DC transmission projects, compared with shallow-buried horizontal ground electrodes, deep well-type vertical ground electrodes have small footprint, low requirements for site selection, small ground resistance and step Low voltage and other advantages have received more and more attention. [0003] example, figure 1 It is a deep well-type vertical ground electrode in the prior art, including a feeder steel pipe 01 extending vertically and a diversion cable 02, the upper end of the diversion cable 02 is connected to a grounding circuit (not shown in the figure), and the conductor The conductor 03 in the lower end of the flow cable 02 is welded to the side w...
