Description

Substation tubular busbar double clamp grounding device

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 double-clamp grounding device for substation tubular busbars 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 busbar in a substation, comprising two clamps and a grounding rod, the clamps include an upper clamp piece and a lower clamp piece, one end of the upper clamp piece and one end of the lower clamp piece The other ends are connected with each other by locking bolts. The lower hoop piece is provided with a boom, and the booms are connected through a rod body, and the grounding rod is hung on the rod body.

One side of the lower hoop piece is provided with an alarm horn, an electric induction chip, a battery and a circuit board of a self-check button, and the circuit boards of the alarm horn, the electric induction chip, the battery and the self-check button are connected by wires.

One end of the upper hoop piece is hingedly connected to one end of the lower hoop piece.

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 personnel to install the grounding rod; one side of the lower hoop is provided with a circuit board of an alarm horn, an electric induction chip, a battery and a self-test button, and the circuit board of the alarm horn, the electric induction chip, the battery and the self-test button The circuit boards are connected by wires, and the electric signal of the maintenance circuit is sensed in time through the electric induction chip, and the alarm horn is used to warn the operator not to misoperate, preventing the occurrence of electric shock and injury accidents. After using the grounding device, the on-duty personnel of the substation can quickly complete the installation of the grounding wire on the tubular bus according to the requirements, ensuring that the operators work within the protection range of the grounding wire and protecting the personal safety of the operators.
