Embodiment Construction

[0021] The present invention will be further described below in conjunction with the accompanying drawings.

[0022] Such as figure 1 , is a structural schematic diagram of the present invention, the raw materials for producing chemical cross-linked materials such as polyethylene resin and cross-linking agent enter the equipment of the present invention through the raw material delivery device 1 at the same time, and are transported to the filter 2 by the delivery pipeline, and the particle size is filtered out. Raw materials that meet the requirements are recovered by the metal separator 21, and raw materials that do not meet the requirements are recovered. The raw materials in the filter 2 are sampled at any time, and the filter 2 is connected to a manual sampler 3 to collect samples of the raw materials and check the purity. Then the raw materials that meet the requirements are passed into the feeding device 4. In the feeding device, the raw material resin and the crosslink...

Abstract

The invention discloses a preparation method for a 110kV-and-above insulating material capable of chemically crosslinking. The preparation method is achieved through the following steps: (1) introducing a polymer resin and a crosslinking agent, which serve as the raw materials, into a totally closed filter device, and then introducing the polymer resin and the crosslinking agent into a totally closed vacuum feeding device for raw material mixing; (2) feeding the mixed raw materials into a reciprocating single screw extruder for melt extrusion, and preparing a crosslinking material; (3) introducing the prepared crosslinking material into a buffer bin through a circulating water system; and (4) spraying an antioxidant into the crosslinking material in the buffer bin in a rolling-over type agitator, then introducing the crosslinking material into a constant temperature heating tower, and introducing the crosslinking material into a storage bin after cooling. The invention further discloses a device employed by the preparation method. According to the invention, sealing is achieved in the whole process, the purity degree of the raw materials is guaranteed, external impurities are not doped, joints of the device are totally closed, and the capacity of the chemical crosslinking material to shield 110kV-and-above voltage is guaranteed.

Description

technical field [0001] The invention relates to a preparation method and equipment for a 110kV and above chemically crosslinkable insulating material, belonging to the technical field of high voltage chemically crosslinkable materials. Background technique [0002] The high-pressure chemical cross-linking material is obtained by adding a cross-linking agent and an antioxidant to the polymer resin, performing melt co-extrusion, and then performing post-treatment. According to the current raw material transportation process, cross-linking equipment, and the purity and processing capacity of the production environment, the cross-linking material produced is mainly a chemical cross-linking material that shields 35kV high voltage. [0003] In order to improve the shielding effect of cross-linked materials, it is currently necessary to produce cross-linked materials that can shield more than 110kV. This kind of chemical cross-linked materials has strict requirements on raw materia...
