Manufacturing method of optical fiber composite insulator and equipment

Abstract

The invention relates to a manufacturing method of an optical fiber composite insulator and equipment. The manufacturing method comprises the following steps of: coating insulating lubricant silicone oil on the inner wall of a hollow epoxy glass rod, connecting one end of an optical fiber placed in an extruder with the tail end of an optical fiber guide head and mounting the optical fiber guide head into an inner hole of the hollow epoxy glass rod; then connecting the inner hole of the hollow epoxy glass rod with a glue extrusion opening of the extruder and when high-temperature vulcanized silicone rubber extruded from the glue extrusion opening of the extruder enters the inner hole of the hollow epoxy glass rod, using the high-temperature vulcanized silicone rubber to promote the optical fiber guide head to drive the optical fiber to advance along the inner hole of the hollow epoxy glass rod; and finally preparing the optical fiber composite insulator through high-temperature vulcanization. The invention has the beneficial effect that while the overall structure of the epoxy glass fiber core rod is ensured, the inner hole is filled by using a method of pressurizing the high-temperature vulcanized silicone rubber so as to protect the optical fiber, save the expensive filling materials, simplify the production process of the optical fiber composite insulator in an electronic mutual inductor, improve the survival rate of the planted optical fiber and reduce the partial discharge level of the optical fiber composite insulator.

Description

technical field [0001] The invention relates to a manufacturing method and equipment for making an optical fiber composite insulator. Background technique [0002] Optical fiber current transformer is mainly composed of three parts: sensing head, insulating support and optical cable. Among them, the insulating support is made of silicone rubber composite insulators, and the optical fiber reaches the low-voltage end along the epoxy glass rod. There are many ways to pass through, mainly winding, slotting, and hollow filling. Both the winding type and the slotting type destroy the overall structure of the epoxy rod, and the composite insulator is extremely easy to damage the optical fiber during the production process; the hollow-filled optical fiber is not easy to damage, but it is quite troublesome to fill the insulating material. It will cause the partial discharge test to fail, which not only wastes insulating materials but also takes a lot of work and time. Contents of...
