Remote-control step voltage alarm trolley and alarm method thereof

Abstract

The invention discloses a remote-control step voltage alarm trolley and an alarm method thereof. The remote-control step voltage alarm trolley comprises a remote controller and a controller, and is characterized in that the controller is located on a remote control trolley body and wirelessly connected with the remote controller, the remote control trolley body is of a structure with the front-and-back length being adjustable, a front chassis is provided with an inserting slot inwards, a rear chassis is provided with an inserting rod inwards, the inserting rod is slidably inserted in the inserting slot, the inserting slot is provided with a fastener between the inserting slot and the inserting rod, the front of the front chassis is provided with an independent driving motor, either a front wheel or a rear wheel is of a metal wheel structure, the metal wheel is connected with a slip ring through a hub, the metal wheel, the hub and the slip ring are electrically connected, the slip ring is connected with an axle in an insulated manner through an insulating ring, and the slip rings are respectively connected to the input end of a step voltage alarm arranged on the remote control trolley body through elastic pieces which are slidably connected with the slip rings and fixed on the remote control trolley body. According to the invention, long-distance remote control can be realized for the trolley, detection is carried out on the periphery of broken-down equipment from far and near, and an alarm is given out when the step voltage exceeds set voltage, thereby greatly reducing occurrence of personal electric shock casualty accidents.

Description

Technical field [0001] The invention relates to a remote control type step voltage alarm trolley and an alarm method thereof. Background technique [0002] When a live wire of an overhead line breaks and falls on the ground, the drop location is the same as the electric potential of the live wire, and the current will flow from the drop location of the wire to the ground, so the ground is centered on the wire drop location to form a potential distribution In the area, the farther away from the landing place, the more scattered the current and the lower the ground potential. If people or livestock stand within 8-10 meters from the wire drop point. An electric shock may occur. This kind of electric shock is called a step voltage electric shock. [0003] When a person receives a stepping voltage, although the current flows along the person's lower body, it forms a path from the feet through the legs and crotch to the feet and the ground. It does not pass through the vital organs of ...

Problems solved by technology

The second is that after the vertical pole is added, most of the fault current flows into the ground through the vertical pole, which reduces the diffuse flow of the horizontal conductor accordingly, so the horizontal current density on the ground surface is greatly reduced, resulting in a greatly reduced electric field intensity in the horizontal direction.

[0012] Ordinary step voltage alarm device still puts the staff in a dangerous electric field, which is prone to personal electric shock accidents
