Embodiment Construction
[0042] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, but not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.
[0043] like figure 1 As shown in the figure, the present invention provides a method and a device for grounding a catenary triangular electrical inspection, comprising the following steps:
[0044] Step 100: Select a grounding point along the track along the direction of the catenary pillar to be grounded, perform electrical inspection on the track grounding point, and selectively install a track grounding wire at the grounding point ...

The invention discloses a catenary triangular electrical inspection and grounding method and device, comprising step 100: Selecting a grounding point along a track along a track on a catenary pillar that needs to be grounded, performing electrical inspection on the track grounding point, and determining the grounding point according to the track. The detection result is to selectively install the track grounding wire at the grounding point; step 200, install the other end of the track grounding wire on a dedicated catenary hanging device, and adjust the minimum included angle between the track grounding wire and the track grounding wire angle; Step 300, select an operating point on the catenary strut along the reverse line direction of the track, the operator uses a hanging device at the operating point to connect the ground wire of the track with the catenary strut, and by setting the adjusting mechanism on the hanging device It is used to limit the included angle with the track ground wire, so when using the hanging device to hang the track ground wire on the catenary column, it can keep a certain distance from the track ground wire and the track.
Description
technical field [0001] The invention relates to the technical field of rail transit catenary, in particular to a method and a device for grounding a triangular electrical inspection of a catenary. Background technique [0002] In the field of rail transit, electrified railway catenary is installed in the maintenance yard of the locomotive depot, the maintenance warehouse of the motor train depot, the maintenance warehouse of the depot, the maintenance warehouse of the passenger station, and the maintenance warehouse of the subway depot. Before maintenance and other work, it is necessary to perform operations such as disconnecting switch off, power inspection, residual power release, and grounding. [0003] The traditional method of electric inspection and grounding is to grind the rail at the catenary pillar where the grounding wire needs to be hung, and connect the grounding end of the grounding wire after the grounding personnel arrive at the scene through the catenary ins...
