Background
When the disconnecting switch (disconnect) is in a separated position, an insulation distance meeting the specified requirement and an obvious disconnection mark are arranged between the contacts; a switching device capable of carrying current in normal loop conditions and current in abnormal conditions (e.g., short circuit) for a specified period of time when in the closed position. The isolating switch is widely applied to high-voltage lines, has a simple working principle and structure, and is mainly characterized by having no arc extinguishing capability and only being capable of switching on and off a circuit under the condition of no load current.
In the 10kV distribution overhead line and the low voltage outlet side of the transformer, a double-column type isolating switch is widely used, and the on-column isolating switch is generally arranged on a cross arm with the height of more than 7 meters above the ground. When the isolating switch needs to be operated, an operator uses the insulating rod on the ground, hooks the iron hook on the insulating rod into the pull ring on the movable contact side of the isolating switch from the side surface of the pull ring to pull up or send down, and the operation of closing and separating the isolating switch is completed. The diameter of a pull ring of a traditional isolating switch is about 5cm, the traditional isolating switch is of a closed annular structure, the size of the pull ring can be reduced along with the increase of the installation height of the isolating switch visually, and the height is higher, so that the judgment of the position of the pull ring by an operator is more difficult. A great deal of time is often spent on aligning the holes and entering the rings during operation. This process is often difficult to accomplish in low lighting or windy weather conditions where the stick is swaying. Such an operation mode greatly consumes physical strength of an operator, and affects efficiency of switching operation.
The traditional mode of operating the disconnecting link is that an operator hooks the pull ring into the side surface of the pull ring by using an insulating rod, and the operator is required to have accurate judgment on the position of the pull ring in space. However, the weight of the insulating rod is more than 5 jin, the weight is heavier along with the increase of the length, and the insulating rod has no supporting point in the air, so the insulating rod is easy to shake, and the operation of operators is inconvenient.
