Ultra-large capacitor, high reliability and high temperature resistance measurement and control cable

Abstract

The invention relates to the technical field of cables, in particular to a supercapacitive, high-reliability, high-temperature-resistant measurement and control cable for a new type of armed helicopter engine. It includes several inner cores, the inner core is wrapped in a general shielding layer, the outer side of the general shielding layer is wrapped with a protective layer, the inner core includes silicon carbide fiber bundles, and the outer side of the silicon carbide fiber bundles is wrapped with a metal layer, The metal layer is wrapped with a composite high temperature resistant insulation layer. The composite high temperature resistant insulation layer includes a first synthetic mica layer with a thickness of 0.08-0.10 mm, the outside of the first synthetic mica layer is wrapped with a first silicon carbide fiber layer, and the surface of the first silicon carbide fiber layer is coated with The first high temperature resistant coating. By adopting a specific structure and process, the present invention solves the contradiction that the supercapacitance of the cable, the high temperature resistance, the electric strength and the limit of the total outer diameter of the cable are mutually restricted and cannot be realized simultaneously. The invention can be used for signal transmission between parts of an aircraft engine.

Description

technical field The invention relates to the technical field of cables, in particular to a supercapacitive, high-reliability, high-temperature-resistant measurement and control cable for a new type of armed helicopter engine. Background technique Although my country has made considerable progress in the research and development of military armed helicopters in recent years, the WZ 10 and WZ 19 have all been publicly displayed at air shows, and the army and aviation units have begun to assemble. However, the core component of the aircraft is also known as the heart of the aviation industry - the overall backwardness of the engine has been delaying the development and installation of my country's armed helicopters. The Wuzhi 10 project, which began in the 1990s, suffered twists and turns due to the engine. The engine power used for WZ-10 is still less than 1000kW, which is more than 60% lower than the 1662kW engine of the same kind of helicopter engine in the world (for Apach...

Problems solved by technology

The invention patent with the patent application number 201210277573X discloses an aircraft engine measurement and control cable, but the engine measurement and control cable has a low capacitance, which still cannot meet the requirements of the continuous development of military armed helicopter engines
