Problems solved by technology

[0003] At present, the enameled wire has the following disadvantages. The temperature range is narrow, usually ranging from -60°C to 250°C. If the electro-hydraulic conversion element is used in an environment exceeding 250°C, a cooling system is required to cool the electro-hydraulic conversion element, which increases the weight of the aero-engine. , cost, increased the complexity of the system, and reduced the reliability of the aero-engine

Embodiment Construction

[0030] In order to make those skilled in the art better understand the technical solutions of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0031] like figure 1 , 2 As shown, a high-temperature enameled wire includes a wire 1, the wire 1 is the conductor of the enameled wire, and this material has good electrical conductivity. In this embodiment, the technician can rotate the material of the wire 1 according to actual needs; the wire 1 is covered with a quartz material layer 2, a silica material layer 3, a glass fiber material layer 4, a glass fiber and silica mixed layer 5, and a silicon material layer 6 sequentially from the inside to the outside. The innermost layer is the insulating material of the enameled wire 1, and has good insulating properties; the silica material layer 3 can solve the piezoelectric effect of the quartz material layer 2, and can improve t...

Abstract

The invention relates to the field of enameled wires, and aims to provide a high-temperature enameled wire with the advantages of high temperature resistance and low temperature resistance. The adopted technical solution is: a high-temperature enameled wire, including a wire, and the outside of the wire is sequentially provided with a quartz material layer, a silicon dioxide material layer, a glass fiber material layer, a glass fiber and silicon dioxide mixed layer, and a silicon material layer. The enameled wire of the present invention can withstand a high temperature of up to 450°C, the electrical properties are basically unchanged, and has better high temperature resistance; it can withstand a low temperature of up to -100°C, the electrical properties are basically unchanged, and has better low temperature resistance; Flexibility and tensile resistance.

Description

technical field [0001] The invention relates to the field of enameled wires, in particular to a high temperature enameled wire and a preparation method. Background technique [0002] The important development direction of aerospace engines is to develop in the direction of miniaturization, integration, ultra-high temperature and ultra-low temperature. Aerospace engine is a very complex control system, which consists of multiple complex subsystems and sub-systems, including many electro-hydraulic conversion components, and enameled wire is an essential device in the electro-hydraulic conversion components . [0003] At present, the enameled wire has the following shortcomings and a narrow temperature range, usually in the range of -60°C to 250°C. When the electro-hydraulic conversion element is used in an environment exceeding 250°C, a cooling system is required to cool the electro-hydraulic conversion element, which increases the weight of the aero-engine. , cost, increase...
