Embodiment Construction

[0026] The following description is given in conjunction with the drawings and a specific embodiment.

[0027] See Figure 1 to Figure 5 . The ceramic cross-arm insulation baffle described in this embodiment includes a first insulation baffle 11a and a second insulation baffle 11b. The shape and material of the first insulation baffle 11a and the second insulation 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 plastic with excellent insulation performance. FRP is a reinforced plastic with glass fiber or its products as a reinforcing material, or glass fiber reinforced plastic, which is a common material in the prior art. The invention selects FRP that is light, hard, non-conductive, high mechanical strength, and corrosion-resistant. The thickness of FRP has a certain influence on the insulation performance. As an indicator, the present invention provides a FRP t...

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 an electric power construction safety protection equipment, in particular to an insulation protection device. Background technique [0002] With the construction and development of power distribution networks, ensuring the quality of customers' power consumption and continuous and reliable power supply are the primary tasks of power supply companies. The use of live working methods to overhaul the distribution network can effectively improve the quality of power supply services, and secondly, it can ensure the safe and reliable operation of the power grid and improve the economic benefits of power supply enterprises. [0003] At present, the linear poles of distribution lines in my country mainly use porcelain crossarms as insulating support materials to fix the wires. The insulated bucket car is used to carry out live work on the distribution line. When working at the position of the conductor on the side of the straight pole, the m...
