Suspended ground pole and application method thereof

Abstract

The invention discloses a suspended ground pole and an application method thereof, and relates to the field of electric machinery. The ground pole comprises a conductive metal pole, wherein an insulating layer wraps the peripheral surface of the conductive metal pole; a plurality of annular grooves (3) are formed in the axial surface of the insulating layer at equal intervals; the depths of the annular grooves (3) are smaller than the thickness of the insulating layer; one segment of conductive metal pole free of the annular insulating layer is arranged on the peripheral surface of the insulating layer between two adjacent annular grooves (3); a stepped cylinder device is clamped between two adjacent annular grooves (3) in a sleeving manner; each stepped cylinder device comprises two pairs of stepped cylinders in one-to-one correspondence; and each two pairs of stepped cylinders sleeve the outer surface of the insulating layer between two adjacent annular grooves (3). The suspended ground pole can ensure sufficient and effective contact area of a wire drained to the ground and the ground pole, prevents the wire drained to the ground from sliding off, and simultaneously solves the problem of an electric wire suspension position set by a worker in a working area.

Description

【Technical field】 [0001] The invention relates to the field of electrical machinery, in particular to a suspended grounding post and a method for using the same. 【Background technique】 [0002] The grounding line is the line directly connected to the earth, and it can also be called a safety return line. When it is in danger, it will directly transfer the high voltage to the earth, which can be regarded as a lifeline. Among them, the grounding wire in the power system is an important tool to ensure the staff when there is an unexpected voltage on the equipment and lines that have been powered off. According to the regulations issued by the Ministry, the ground wire must be made of bare copper soft wire above 25mm2. The lower part of the existing distribution network grounding ring is connected with the bare part, which is easy to cause trees and metal objects to collide; at the same time, the contact point of the grounding ring is small, the grounding is unreliable and easy...

Problems solved by technology

However, although new changes have been made to the outdoor wire connection method, such as the heat-shrinkable insulation material on the busbar, holes are opened on the busbar, and the grounding ring is fixed by pre-embedded bolts, but because the grounding rings are in the same direction, the same phase location, and the contact area between the grounding ring and the grounding ring is small due to the soaking in the wind and rain all year round, and the hanging grounding wire is prone to fall off and rust, so that it cannot lead the current into the earth well, and there is a serious danger; More importantly, the grounding ring is fixed under the ventral side of the wire for a long time. When passers-by carry heavy metal objects, it is easy to cause insufficient safety distance, which may cause discharge and cause personal injury to passers-by.

At present, although such problems have not occurred in large numbers, there are a lot of hidden risks, and once an outbreak occurs, the consequences will be disastrous
