Description

Special wiring device for GIS arrester line

technical field

The utility model relates to the technical field of construction auxiliary equipment for arrester lines, in particular to a special wiring device for GIS arrester lines.

Background technique

The function of the arrester is to protect various electrical equipment in the power system from being damaged by lightning overvoltage, operating overvoltage, and power frequency transient overvoltage. In the ultra-high voltage system, it will also be used to limit the internal overvoltage or as a backup protection for the internal overvoltage. An electrical device that can release lightning or overvoltage energy in the power system operation, protect electrical equipment from instantaneous overvoltage hazards, and cut off freewheeling so as not to cause a short circuit to the system ground. The arrester is usually connected between the live wire and the ground, and is connected in parallel with the protected equipment. When the overvoltage value reaches the specified operating voltage, the arrester will act immediately, and the charge will flow to limit the overvoltage amplitude and protect the insulation of the equipment; after the voltage value is normal, the arrester will quickly return to its original state. However, in the construction of lightning arrester lines, ordinary wiring devices are often not firmly wired, and it is difficult to ensure that the power supply system is not seriously threatened by lightning overvoltage, operating overvoltage, and power frequency transient overvoltage, which may seriously damage the power line. And power equipment, even threatening the safety of people's lives, the consequences are unimaginable.

Utility model content

The purpose of the utility model is to provide a special wiring device for GIS lightning arrester lines that can quickly and firmly connect the lightning arrester lines.

A special wiring device for GIS lightning arrester lines, comprising a casing, an aluminum sheet and fixing screws, and two screw installation holes are arranged on the casing.

The fixing screws pass through the screw mounting holes to compress the aluminum sheet.

The aluminum sheet is installed inside the casing.

The cross-section of the aluminum sheet is semicircular.

The utility model arranges the bushing, places the connector of the lightning arrester connection line in the casing, sets the aluminum sheet on the connector of the lightning arrester connection wire, presses the aluminum sheet and the connector of the lightning arrester connection wire through the set fixing screw, and realizes the firmness of the lightning arrester connection wire joint. connect. It effectively avoids the damage of power lines and power equipment and hidden dangers to personal safety caused by poor contact of lightning arrester connecting wire connectors. It is simple, practical and safe.

Description of drawings

Below in conjunction with accompanying drawing, the utility model is further described:

Fig. 1 is the structural representation of the utility model.

Detailed ways

As shown in FIG. 1 , a special wiring device for a GIS arrester line includes a sleeve 3 , an aluminum sheet 4 and a fixing screw 1 , and two screw mounting holes 2 are arranged on the sleeve 3 . The fixing screw 1 passes through the screw mounting hole 2 and presses the aluminum sheet 4 tightly. The aluminum sheet 4 is installed inside the casing 3 . The cross section of the aluminum sheet 4 is semicircular. The utility model arranges the bushing, places the connector of the lightning arrester connection line in the casing, sets the aluminum sheet on the connector of the lightning arrester connection wire, presses the aluminum sheet and the connector of the lightning arrester connection wire through the set fixing screw, and realizes the firmness of the lightning arrester connection wire joint. connect. It effectively avoids the damage of power lines and power equipment and hidden dangers to personal safety caused by poor contact of lightning arrester connecting wire connectors. It is simple, practical and safe.
