Problems solved by technology

However, as can be seen from its description, this method can only produce insulators with uniform size sheds, where the sheds are all the same size in one insulator
For composite insulators with superior performance and with sheds of different sizes, this production method is powerless

Embodiment Construction

[0025] First, please refer to FIG. 1 to briefly introduce the structure of the composite insulator manufactured by the method of the present invention. As shown in FIG. 1 , this composite insulator with large and small sheds includes: a supporting component 5 on which large sheds 3 and small sheds 6 are arranged at intervals. The two ends of the insulator are respectively an upper end connecting flange 7a and a lower end connecting flange 7b.

[0026] The equipment used in the manufacturing method of the composite insulator of the present invention includes a rotary table, a material injection device, a mold, etc., and these devices will be introduced together in the detailed description of the method later.

[0027] Please refer to FIG. 1 and FIG. 2 in combination. FIG. 2A-FIG. 2D respectively show the conditions of each step of the manufacturing method of the present invention. Firstly, the method of the present invention includes a step of fixing the support member 5 on a ...

Abstract

This invention relates to a manufacturing method for a compound insulator with big and small umbrella aprons and their die sets including: a, fixing a bearing unit on a rotary stand, a rotary stand post drives the bearing unit to rotate, b, encasing the top connection flange on the bearing unit, encasing the seal loop and big umbrella apron die on the bearing unit d, injecting a compound liquid material into the big die, e, moving the seal loop and the big die down after the liquid is set, f, plugging a small umbrella apron board into the big die and injecting compound liquid material into the small one, g, taking out the small one and moving down the seal loop and the big apron, h, repeating step d to g if it has reached to the height or the number of the aprons, then the seal loop and big die are taken out to encase the bottom connection flange.

Description

technical field [0001] The invention relates to the field of high-voltage (10-750KV) electric power, in particular to a method for manufacturing composite insulators with large and small sheds, and also provides a mold suitable for manufacturing composite insulators with large and small sheds. Background technique [0002] Electrical insulators used in the voltage range of 10kV to 750kV were earlier made of lower-cost glass or ceramic materials. The electrical performance of insulators made of these materials is high. If they are operated and used in a standardized and careful manner, It can be used on input wires and power station equipment for a long time. As the voltage increases, the size of the insulator will increase. Due to the high quality of the glass or ceramic material, the weight of the insulator will also increase, which will significantly increase the workload of transportation and installation. improve. [0003] On this basis, the industry has begun to use p...
