Problems solved by technology

[0003] Since the placement of equipment in the lightning protection power distribution cabinet involves the safety and smooth flow of electricity, it is necessary to ensure its uninterrupted normal operation. However, due to the influence of the placement environment, it will inevitably come into contact with dangerous gases, such as CO, etc. However, the general lightning protection distribution cabinet does not have the detection capability of this kind of gas, and cannot guarantee normal work and personnel safety in the case of gas leakage

Abstract

The invention relates to an anti-lightning power distribution cabinet based on a CO gas detection function. The anti-lightning power distribution cabinet is provided with a CO gas sensor, the CO gas sensor comprises a Si substrate, a silicon oxide thin film formed on the Si substrate, a W film placed on the silicon oxide thin film, a WO3 nanowire thin film formed on the W film, a SnO2 nano thin film covering the WO3 nanowire thin film, two Pt electrodes manufactured on the SnO2 nano thin film, and a heating module located on the Si substrate. The anti-lightning power distribution cabinet is high in CO gas sensitivity, short in response time and good in repeatability and stability.

Description

technical field [0001] The present application relates to the field of lightning protection distribution cabinets, in particular to a lightning protection distribution cabinet based on CO gas detection function. Background technique [0002] The power distribution cabinet is the power distribution equipment used for power distribution, control, metering and cable connection in the power supply system. It is generally a steel structure, square, and placed on the ground. Various power modules are placed in it and connected by wiring. [0003] Since the placement of equipment in the lightning protection power distribution cabinet involves the safety and smooth flow of electricity, it is necessary to ensure its uninterrupted normal operation. However, due to the influence of the placement environment, it will inevitably come into contact with dangerous gases, such as CO, etc. However, general lightning protection distribution cabinets do not have the ability to detect this kind ...
