Abstract

The invention relates to a sensor, a manufacturing method, a detection system with the sensor and a detection method. The invention relates to a sensor for detecting partial discharge in a sulfur hexafluoride circuit breaker based on a carbon nanotube film, a manufacturing method, a detection system and a detection method. By preparing a highly oriented carbon nanotube film, carbon nanotubes are arranged in parallel along a direction perpendicular to an electrode, so that more carbon nanotubes participate in the detection of sulfur hexafluoride decomposition products, and the detection sensitivity can be improved; the suspended structure increases the overall surface area, enhances gas convection, and can further improve the sensor performance; in addition, a high-uniformity film as long as several meters can be quickly obtained by a dry spinning method, so that the productibility of the product is improved, and the production cost is reduced.

Description

Technical field: [0001] The present invention relates to the technical field of sulfur hexafluoride circuit breakers, in particular to a carbon nanotube film-based sensor for detecting partial discharge in a sulfur hexafluoride circuit breaker and a method for making the sensor, as well as a detection system with the sensor and a sensor based on the carbon nanotube film. The detection method of the detection system. Background technique: [0002] Due to its compact structure and high reliability, sulfur hexafluoride circuit breakers have been widely used in current power transmission and distribution systems. However, examples in actual operation show that in the process of manufacturing, transportation, and assembly, circuit breakers will inevitably produce hidden dangers that affect insulation performance, such as surface metal burrs, protrusions, and suspended particles. The partial discharge caused by these hidden dangers has become the main reason for the insulation fa...
