Abstract

The invention discloses an insulator umbrella skirt, insulators comprising the umbrella skirt as well as manufacturing methods for the insulator umbrella skirt and the insulators. The insulator umbrella skirt is a hollow glass-reinforced-plastic umbrella skirt which is manufactured by soaking three-dimensional glass fibre fabric in epoxy resin. The manufacturing method for the insulator umbrella skirt comprises the following steps of: a. making the three-dimensional glass fibre fabric into an annular sheet and then soaking the annular sheet in the epoxy resin; b. uniformly smearing resin containing ceramic powder on the surface of the annular sheet when solidification begins, later placing the annular sheet in an umbrella skirt die; and c. increasing temperature for shaping and then stripping the die after solidification, thereby manufacturing the hollow glass-reinforced-plastic umbrella skirt. The invention also discloses a hollow insulator and a solid insulator which comprise the insulator umbrella skirt, as well as manufacturing methods for the hollow insulator and the solid insulator. The insulators and the insulator umbrella skirt are suitable to being used in high-voltage circuits.

Description

technical field [0001] The invention belongs to the field of insulators, and in particular relates to an insulator shed, an insulator containing the shed, and a manufacturing method of the shed and the insulator containing the shed. Background technique [0002] Usually, the high-voltage post insulators used outdoors are generally porcelain rod insulators. The sheds of the insulators include porcelain sheds, fiberglass sheds, and glass sheds. With the continuous improvement of the level of science and technology, people put forward higher requirements for the electrical equipment of power stations. Composite post insulators for power stations are not only required to have high insulation performance and various electrical properties, but also to be able to withstand the gravity and tension of the conductors, wind force, ice weight, self-weight of the insulator, conductor vibration, equipment operating mechanical force, Effects of short-circuit electromotive forces, earthqua...
