Description

Rectangular Busbar Grounding Wire Hanging Ring

technical field

The utility model relates to a rectangular bus bar ground wire hanging ring.

Background technique

At present, when the rectangular busbar on the low-voltage side of the power transformer needs to be installed with a grounding wire, it is usually realized by directly installing the grounding wire on the exposed conductive part reserved on the rectangular busbar. Usually, in order to maintain a sufficient safety distance, the rectangular bus bar on the low-voltage side of the power transformer is usually erected relatively high, and it is erected through a corridor bridge, and there are inevitably some fixed brackets supporting the insulators. This makes switching operators not only need to forcefully support the heavier grounding wires when installing the grounding wires, but also have to avoid the fixed brackets supporting the insulators during installation. Due to the structural form and certain thickness of the rectangular busbar, the dedicated ground wire bayonet needs to be opened to a certain degree in advance, and must be aligned with the rectangular busbar at the same time. For the tightening type rectangular bayonet grounding wire, the tightening operation is realized by rotating the grounding pole. When tightening, not only the pre-aligned bayonet is easy to deflect, but also for wearing thick insulating gloves. The physical strength of the personnel who operate the ground wire is also a great test. For the buckle-type rectangular bayonet grounding wire, although it is easier to align and contact the upper rectangular busbar during operation, due to the physical strength of the personnel, the pressing force of the buckle-type grounding wire is usually small, and sometimes It is easy to be subjected to the gravity of the grounding wire to make the bayonet open and separate from the busbar, and the contact degree is not easy to meet the requirements. In addition, because the exposed conductive parts reserved for the rectangular busbar are prone to dirt and rust, additional steps such as decontamination and rust removal must be added before installing the grounding wire. Due to the cumbersomeness of these operations, it often takes up a lot of switching operation time, which seriously affects the efficiency of switching operations.

Utility model content

The utility model provides a rectangular busbar grounding wire hanging ring, which is convenient, safe and efficient to operate when installing the grounding wire, ensures good contact of the grounding wire, and reduces the physical strength of switching operators at the same time. The technical scheme that the utility model solves its technical problem adopts is:

The rectangular busbar ground wire hanging ring includes a clamping part, a suspension part and a plurality of bolts, the clamping part includes an upper plate, a lower plate and a side plate, and the side plate connects the upper plate and the lower plate to form a U-shaped frame structure, The lower plate is provided with through holes corresponding to the bolts, the hanging part is connected below the clamping part and close to the side panel, the hanging part is U-shaped, and the hanging part includes two vertical bars and a horizontal bar It is connected between the bottom ends of two sections of vertical rods, the top of the vertical rods is connected to the bottom surface of the lower plate, the bolt vertically passes through the through hole, the upper end of the bolt is provided with a flat pressing piece, the bolt The lower part is provided with nuts.

In a preferred embodiment: the surface of the pressing sheet is a file surface structure.

In a preferred embodiment: the clamping part and the hanging part are made of tin-coated material.

Compared with the background technology, this technical solution has the following advantages:

1. The clamping part is a U-shaped frame structure with side openings, which can be easily clamped on rectangular busbars of various widths, and fixed on the rectangular busbars through bolt adjustment and compression, and can be applied to any thickness and any width rectangular busbar. When the grounding wire needs to be installed on the rectangular busbar on the low-voltage side of the power transformer, by pre-installing the hanging ring on the rectangular busbar on the low-voltage side of the power transformer, when the power transformer needs to be repaired, or on the low-voltage side of the power transformer When the rectangular busbar needs to be hung with a ground wire, the ground wire can be installed on the suspension part, so that the operation of installing the ground wire can be realized quickly and in good contact, and the operation of removing the ground wire is also very convenient and quick.

2. The bolt adopts the structure of the file surface to press the rectangular busbar to ensure the fastness and contact with the rectangular busbar.

3. The clamping part and hanging part are made of tin-coated material, which can ensure that the contact resistance with rectangular busbars of various materials meets the requirements of power production.
