Abstract

The invention discloses a digital voltage monitor of an intelligent transformer substation based on humidity detection. The voltage monitor is provided with a ZnO-based humidity sensitive sensor module; a humidity sensitive element part of the ZnO-based humidity sensitive sensor module adopts a silicon nano-pore column material as a substrate; a zinc oxide nano wire combined graphene material is used as a sensitive material; a device structure is an interdigital electrode type; the structure has an extremely large specific surface area and a good gas dispersion channel; and furthermore, a surface layer of the voltage monitor is provided with a dehumidified polyvinyl alcohol-ethylenediamine tetramethylenephosphonic acid-polysulfone-based film hollow fiber composite film assembly, so that the humidity induction and the humidity absorption and corrosion-proof functions of the voltage monitor are greatly improved.

Description

technical field [0001] The invention relates to the field of electricity, in particular to an intelligent substation digital voltage monitor based on humidity detection. Background technique [0002] The voltage monitor is a statistical voltage monitor that continuously monitors and counts the voltage deviation caused by the slow change of the normal operating state of the power system. With monitoring, analysis, memory, query, parameter setting and other functions. Suitable for low pressure system, high pressure system, etc. [0003] However, because the voltage monitor is used in the power system, when the humidity of the environment where it is located is high, it is easy to cause various accidents and cause unnecessary losses. Contents of the invention [0004] The purpose of the present invention is to avoid the above-mentioned disadvantages in the prior art and provide a digital voltage monitor for intelligent substation based on humidity detection. [0005] The o...
