Abstract

The utility model discloses a transformer station tubular busbar double-clamp grounding device. The device comprises two hoop clamps and a grounding wire bar, wherein the hoop clamp includes an upper hoop clamp piece and a lower hoop clamp piece, two ends of the upper hoop clamp piece are connected with two ends of lower hoop clamp piece by locking screws, the lower hoop clamp pieces each is provided with a hanging arm, the hanging arms are connected by a rod, and the grounding wire bar is hung on the rod. For a small tubular busbar, the grounding wire hanging device is usually a flat-type or double-spring-hook-type wire clamp which has a small aperture and cannot be hung, a single-clamp grounding device is used, arc on the bottom of the semicircle clamp is short, and the grounding wire bar cannot be hung. According to the utility model, the double grounding hoop clamps are arranged on the transformer station busbar, the lower hoop clamp pieces are provided with the hanging arms, the hanging arms are connected by the rod, and the grounding wire bar is hung on the rod, so that the power personnel can conveniently mounting the grounding wire bar.

Description

A double-clamp grounding device for tubular busbars in substations

technical field

The utility model belongs to the technical field of electric power maintenance equipment, in particular to a double clamp grounding device for a tubular busbar of a substation.

Background technique

The medium and low-voltage side of the main transformer of the substation is connected to the indoor high-voltage equipment by a tubular busbar. When the main transformer body has a power outage, the "Safety Regulations" require that the working range of the staff must be within the protection range of the grounding device, and each side of the main transformer must be hung with a grounding wire or Push up the grounding knife switch. At present, because the grounding wire suspension device is a flat-mouth or double-hook type clamp with a small diameter and a large diameter of the tubular busbar, all kinds of grounding wires cannot be directly hung on the tubular busbar. For super-large tubular busbars, a single-clamp grounding device can be used, but for small tubular busbars, since the grounding wire suspension device is a flat-mouthed or double-hook type clamp, the caliber is small and cannot be suspended, a single-clamp grounding device is used , The arc at the lower end of the semicircular hoop is short, and the grounding rod cannot be suspended, so that the operator loses the protection of the grounding wire, and personal safety cannot be guaranteed.

Utility model content

The utility model provides a single clamp grounding device for a tubular bus bar of a substation which is convenient, fast, accurate, high in safety and firm in structure for suspending the grounding wire.

A double clamp grounding device for a tubular bus bar in a substation, comprising two clamps and a grounding rod, the clamps include an upper clamp piece and a lower clamp piece, the two ends of the upper clamp piece and the lower clamp piece They are connected by locking bolts, and the lower hoop piece is provided with a boom, and the booms are connected by a rod body, and the grounding rod is hung on the rod body.

One end of the grounding bar is provided with an LED lamp and a power supply, and a switch is provided on the LED lamp, and the switch is connected with the LED lamp and the power supply through wires.

Described power supply adopts lithium battery.

The utility model is achieved in this way, the hoop includes an upper hoop piece and a lower hoop piece, the two ends of the upper hoop piece and the lower hoop piece are connected by locking bolts, which can facilitate the installation and adjustment of electric personnel ; For small tubular busbars, since the grounding wire suspension device is a flat-mouthed or double-hook type clamp with a small diameter, it cannot be suspended. A single-clamp grounding device is used. The arc at the lower end of the semicircular hoop is short, and the grounding rod cannot be used Suspension, by setting double-clip grounding hoops on the tubular busbar of the substation, the lower hoop piece is provided with a boom, the booms are connected by a rod body, and the grounding rod is hung on the rod body, It is convenient for electric power personnel to install grounding rods; after using the grounding device, the personnel on duty in the substation can quickly complete the installation of grounding wires on the tubular bus according to requirements, ensuring that the operators work within the protection range of the grounding wires and protecting the safety of the operators. Personal safety.
