Fault Monitoring System for Underground Substation HVAC Ventilation System

Abstract

The invention discloses a fault monitoring system for heating, ventilating and ventilating systems of underground substations. The monitoring system includes at least one light-emitting diode and a miniature air-conditioning device for detecting the wind force at the air outlet located at the terminal air outlet of a ventilation pipe to be detected. A wind power generator, the micro wind power generator has a fan structure, the output terminal of the micro wind power generator is connected to the light emitting diode and supplies power to it, the rated output power of the micro wind power generator is equal to the sum of the luminous power of the light emitting diode match. It has the following advantages: the monitoring system is ingeniously designed, and the health status of the ventilation system is fed back by monitoring the exhaust wind force of the ventilation duct, and the monitoring effect is better and more accurate.

Description

technical field [0001] The invention relates to a substation monitoring system, in particular to an underground substation HVAC fault monitoring system. Background technique [0002] With the rapid development of the urban economy, the electricity load is also increasing rapidly, and the load density in the downtown area is getting higher and higher. However, the planning and site selection of substations are subject to many constraints such as land use and the environment, and the contradiction between power grid construction and urban construction has become increasingly prominent. , Underground substations can not only reduce the area occupied by substations, improve the utilization rate of land resources, but also reduce the impact on the surrounding environment and beautify the environment, which is also the development trend of urban substations. [0003] The function of the HVAC ventilation system of the underground substation is to adjust the airflow in the basement ...

AI Technical Summary

Problems solved by technology

At present, natural air supply and mechanical exhaust are mainly used. If the ventilation system has fan blockage, reverse rotation, loose belt, air leakage from the air duct, loose fan shaft and impeller, excessive system resistance or partial blockage, etc. Insufficient air pressure in the pipeline, or even negative pressure, a large amount of hot air and harmful substances will spread to the equipment area and even the personnel activity area, posing a serious threat to the safety of on-site equipment and personnel

[0004] The existing HVAC monitoring system only detects the fan status of the ventilation system, and cannot give timely warnings for the above-mentioned other faults

Some maintenance personnel use the method of tying red cloth strips on the air outlet and installing remote video to monitor, but when a fault occurs, it cannot be found immediately, and the effect is not good
