Production technology of exciter coil

Abstract

The invention relates to a production technology of an exciter coil. The production technology comprises the following steps: 1) using NMN composite insulation paper to cover an insulation layer outside the stainless steel pipe of an exciter, binding one layer of mica tape outside NMN, tightly binding a heat-shrinkable belt to the outside of the mica tape; 2) binding 5-15 layers of polyester inferior amine lacquered wires outside the heat-shrinkable belt, wherein one layer of imine film is placed between each two adjacent polyester inferior amine lacquered wires and one layer of alkali-free glass tape is covered outside the outermost polyester inferior amine lacquered wires; 3) distributing three sections of coils outside the stainless steel pipe of the exciter, electrically connecting the coils in series, sleeving varnished cloth pipes outside the series wires of the coils, placing a sensistor on the outer layer of the middle coil to obtain a semi-finished product; and 4) soaking the entire semi-finished product in ET-90A insulating varnish once, wherein varnish is avoided to enter in the stainless steel pipe of the exciter during soaking. The prepared product has good insulating property, excellent electrical properties and long service life.

Description

Technical field: [0001] The invention relates to the technical field of exciter production, in particular to a production process for a coil used on an exciter used to prevent crude oil from condensing and clogging an oil pipeline. Background technique: [0002] Existing exciters used to prevent crude oil condensation and blockage on oil pipelines are all insulated and wound with coils. Due to the harsh working environment of oil pipelines and long service life, the coils are required to have excellent electrical properties. Due to its poor insulation performance, the coil cannot guarantee long-term safe and normal operation under the DC voltage of 100V, which makes the service life of the exciter short. Invention content: [0003] The object of the present invention is to provide an exciter coil production process aimed at the deficiencies of the prior art. The products produced by it have good insulation performance, excellent electrical performance and long service life...

Problems solved by technology

[0002] Existing actuators used to prevent crude oil condensation and blockage on oil pipelines are all insulated and wound with coils. Due to the harsh working environment of oil pipelines and the requirement of long service life, the coils are required to have excellent electrical properties. Due to the poor insulation performance of the coil, it cannot guarantee long-term safe and normal operation under the working state of DC voltage of 100V, which makes the service life of the exciter short
