The technical scheme of the utility model is as follows:

An insulated bridge for GIS busbar bushings, including a safety guardrail, a ladder cross plate, an inclined ladder and a stable stand. The two ends of the ladder are provided with connecting sleeves, and the ladder horizontal plate is movably connected with the stable stand through the connecting sleeves at both ends; The ladder and the stabilizing stand are fixed by a reinforced transverse tie rod, and the bottom of the stabilizing stand is provided with a stabilizing stand base.

The stable stand is provided with a cross arm.

The reinforcing transverse tie rods are respectively connected with the stabilizing stand and the inclined ladder through hoops arranged at both ends thereof.

The lower parts of both ends of the safety guardrail are provided with safety guardrail plugs, and the top of the stable stand is provided with a safety guardrail socket, and the safety guardrail is inserted into the safety guardrail socket through the safety guardrail plug.

The said ladder cross plate is a telescopic set structure.

The stabilizing stand is cylindrical, grooves are arranged on both sides of the cylindrical stabilizing stand along the axial direction, and slots are arranged on the body of the cylindrical stabilizing stand.

There is at least one card slot.

The cross-sectional shape of the slot is horizontally L-shaped.

The connecting sleeve is a hollow ring, the inner wall of the hollow ring is provided with protrusions, and the inner wall of the hollow ring matches the outer wall of the stable stand.

The GIS bus bushing insulation bridge of the utility model has the following advantages and beneficial effects:

(1) Using high-strength insulating materials, it is easy to transport, light and beautiful, and can be loaded and unloaded quickly, effectively ensuring personal safety and improving the reliability of power supply.

(2) The safety of the person and equipment is guaranteed, and it is reasonably connected with the safety fence, meeting the requirements of safety regulations, and ensuring the safety of the person and the power grid.
