Embodiment 1

[0019] Such as figure 1 As shown, the insulating ladder body 11 is included, the upper end of the body is provided with a right-angled U-shaped insulating plate 10, the top of the insulating plate is provided with a crossbeam 8, and the two ends of the crossbeam are fixed with the insulating plate by through-hole bolts 9; One end of the two support rods is connected, and the other ends of the two support rods are fastened with the beam to form a tripod; the upper part of the tripod is provided with an aluminum alloy plate 1, and the lower part of the aluminum alloy plate is provided with a bolt 4, and the top of the bolt is inlaid inside the aluminum alloy plate. The alloy plate and the bolt are fastened by the fixing screw 2; the lower surface of the aluminum alloy plate is located on both sides of the bolt with arc-shaped grooves 3, the inner diameter of the arc-shaped groove matches the outer diameter of the busbar, and the inner diameter of the arc-shaped groove matches the...

Embodiment 2

[0021] The bolts pass through the top of the aluminum alloy plate, and other structures are the same as in Embodiment 1.

[0022] Before using the invention, the groove and the horizontal bar are in an open state. When in use, the ground staff presses the lower part of the insulating ladder body, and the operator lifts the upper part of the insulating ladder body, erects the insulating ladder, then lifts the insulating ladder and inserts it at the middle of the double busbar, rotates 90°, and the arc-shaped concave The groove is aligned with the busbar and hung on the double busbar. At this time, the ground electrician rotates the insulating ladder to move the nut on the horizontal bar up until the horizontal bar seals the arc-shaped groove, locks the busbar to stop rotating, and adjusts the angle of the insulating ladder so that The live working personnel are comfortable when going up and down the insulation ladder, and the distance between the person and the ground, the comb...

Abstract

The present invention relates to a transformer substation double bus balance enclosure insulating ladder. The transformer substation double bus balance enclosure insulating ladder comprises an insulating ladder body, the upper end of the body is equipped with an insulating plate, and the upper part of the insulating plate is equipped with a crossbeam. The two ends of the crossbeam are connected with one ends of the supporting rods respectively, and the other ends of the two supporting rods are buckled with the crossbeam to form a triangular rack. An aluminum alloy plate is arranged above the triangular rack, a bolt is arranged below the aluminum alloy plate, and the lower surface of the aluminum alloy plate at the two sides of the bolt is equipped with grooves. The inner surface of a nut sleeves on the bolt, the outer surface of the nut is fixedly connected with the buckled top ends of the supporting rods, and a transverse lever is welded on the outer surface of the nut. The transformer substation double bus balance enclosure insulating ladder of the present invention guarantees that the transformer substation live-line work is convenient, rapid and safe. The insulating ladder is hung on double buses to keep the double buses horizontal and is locked automatically after being hung, so that the insulating ladder can be prevented from falling off from the buses, the on-site work safety is improved, and the personal and equipment safety is guaranteed.

Description

technical field [0001] The invention relates to an insulating ladder, in particular to a double busbar balanced door insulating ladder for substation double busbar live work, which belongs to the technical field of electric power transmission. Background technique [0002] During the operation and maintenance of the power system, it is often necessary for operators to enter the strong electric field to install and remove the connecting wires. After the connecting wires are removed, the maintenance personnel can perform power-off maintenance on the isolating switch, rotary switch, and vertical switch. There is no need for operators to guide spacing and load shedding. However, if the connecting wires cannot be removed while live, it is necessary to conduct intervals and shed loads. Then the operator needs to operate more than 200 times each time, which is easy to cause accidental pull and wrong connection, which will cause large-scale power outages, posing safety hazards and c...
