Embodiment Construction

[0026] The following will be described in conjunction with the accompanying drawings and a specific embodiment.

[0027] see Figure 1 to Figure 5 . The porcelain cross-arm insulating baffle described in this embodiment includes a first insulating baffle 11a and a second insulating baffle 11b, and the shapes and materials of the first insulating baffle 11a and the second insulating baffle 11b are completely the same. Both the first insulation baffle 11a and the second insulation baffle 11b are rectangular plates made of glass fiber reinforced plastics with excellent insulation properties. FRP is a reinforced plastic made of glass fiber or its products as a reinforced material, or glass fiber reinforced plastic, which is a common material in the prior art. The present invention selects light and hard, non-conductive, high mechanical strength and corrosion-resistant glass fiber reinforced plastics for use. The thickness of FRP has a certain influence on the insulation perform...

Abstract

The invention discloses a porcelain cross arm insulation baffle. A first insulation baffle and a second insulation baffle are connected to form the insulation baffle with a hole in the middle portion, a first insulation seam shielding plate and a first semi-circular notch are arranged on the connecting edge of the first insulation baffle, and a second insulation seam shielding plate and a second semi-circular notch are arranged on the connecting edge of the second insulation baffle. A first semi-ring soft cushion is mounted on the first semi-circular notch, and a second semi-ring soft cushion is mounted on the second semi-circular notch. The porcelain cross arm insulation baffle enlarges the insulation shielding range of wire position operation. The seam between the first insulation baffle and the second insulation baffle is covered effectively, and insulation safety is improved. Further, the insulation baffle cannot loose and be off the position on the mounting part of a porcelain cross arm.

Description

technical field [0001] The invention relates to a safety protection device for electric power construction, in particular to an insulation protection device. Background technique [0002] With the construction and development of power distribution network, it is the primary task of power supply enterprises to ensure the quality of power consumption and continuous and reliable power supply for customers. The use of live work to overhaul the power distribution network can effectively improve the quality of power supply service, and secondly, ensure the safe and reliable operation of the power grid and improve the economic benefits of power supply enterprises. [0003] At present, the straight rods of my country's distribution lines mainly use porcelain cross-arms as insulating support materials to fix the wires. The insulated bucket arm truck is used to carry out live work on the distribution line. When working at the position of the wire on the side of the straight pole, the...
