Problems solved by technology

[0003] However, the electrical cabinets in the related art have the following technical problems: in the process of use, the surrounding environment of the electrical cabinets sometimes has high humidity, which may cause equipment corrosion and failures in severe cases. Scattered, and at present, only the method of manual regular inspection is used to check the humidity of the electrical cabinet one by one, so a lot of manpower and material resources are wasted and it is not easy to monitor

Abstract

The invention discloses an electrical cabinet based on a high-sensitivity humidity detection function. A ZnO-based humidity-sensitive sensor is mounted on the external of a cabinet body of the electrical cabinet; a humidity-sensitive component of the ZnO-based humidity-sensitive sensor is provided with a base made of a silicon nanoporous pillar material; a zinc oxide nanometer wire and a graphene material are combined with each other and are made into a sensitive material; a device structure has an interdigital electrode model. The structure has ultrahigh specific surface area and excellent gas diffusion channel. Besides, a dehumidifying polyvinyl alcohol-ethylene diamine tetra(methylene phosphonic acid)-polysulfone base membrane hollow fiber compound film component is arranged on the surface of the electrical cabinet, the humidity sensitivity of the electrical cabinet is greatly increased and the moisture absorption and anti-corrosion functions are promoted.

Description

technical field [0001] The invention relates to the field of electric power, in particular to an electrical cabinet based on a highly sensitive humidity detection function.
