Problems solved by technology
At present, in power system construction, temporary grounding rods are generally all mechanical structural parts and are often placed at a height of tens of meters. The temporary grounding rods are often loosened or fall off due to wind or other factors. Discovery led to some unnecessary shock incidents
In addition, after the construction is completed, it is impossible to be sure that all the temporary grounding rods have been removed, and it often happens that the power grid short-circuit event occurs because the temporary grounding rods are not removed in time when the power is re-powered.
In summary, there is still no temporary grounding rod that can overcome the above shortcomings to meet the safety requirements of electric power construction

The invention relates to safety grounding equipment needed in the maintenance and construction of a power transmission line, and particularly relates to an intelligent temporary grounding rod with a clamping state monitoring function. The temporary grounding rod comprises a clamping mechanism, a grounding system and an information monitoring system; the clamping mechanism comprises a lower end clamping mechanism and an upper end clamping mechanism; the grounding system consists of a U-shaped iron and a grounding lead, and a clamping state detection unit is arranged at one side where the lead is clamped by the U-shaped iron; the information monitoring system consists of a local information management device and the clamping state detection unit, the local information management device is used for displaying the clamping state of each grounding rod, the clamping state detection unit outputs a clamping state signal by pushing a sliding bar to trigger a photoelectric switch through the clamped lead, and data interaction can be performed between the two in a wireless manner. The temporary grounding rod is simple and practical, the lead clamping state of the temporary grounding rod can be monitored in real time, and the temporary grounding rod has an excellent man-machine interaction interface and can effectively prevent the occurrence of induced electricity accidents so as to improve the power construction safety.
Description
technical field [0001] The invention relates to a safety grounding device required for maintenance and construction of a power transmission line, in particular to a temporary grounding rod with a clamping state monitoring function. Background technique [0002] At the construction site of transmission and distribution line inspection and maintenance, it is necessary to directly ground the transmission line through temporary grounding rods to avoid accidents caused by induction electricity and wrong power-on operation. , so as not to cause the power grid to collapse due to the short circuit of the transmission line when the power is re-powered. At present, in power system construction, temporary grounding rods are generally all mechanical structural parts and are often placed at a height of tens of meters. The temporary grounding rods are often loosened or fall off due to wind or other factors. Discovery resulted in some unnecessary shock events. In addition, after the cons...
