Technical Field

[0001] The invention relates to the technical field of substation switch cabinet control, in particular to a fire monitoring system and a control method. Background Art

[0002] Switchgear is the most common power equipment in substations, and plays a role in distributing and transmitting electric energy in power systems. The rapid development of the economy and society has also put forward higher requirements for the safety of power systems. However, in recent years, fires in switchgear cable rooms have occurred from time to time, causing huge losses to power grid assets and seriously threatening the lives of substation operators.

[0003] Cables, current transformers, lightning arresters, grounding switches and other equipment are arranged in the cable room. Usually, there are about 30 switch cabinets arranged in a row in a substation. When a fire occurs in the cable room, on the one hand, due to the closed space, the fire cannot be discovered from outside the cable room in the first place, causing the fire to continue to develop; on the other hand, when the fire develops outside the cable room, it is very easy to spread to the adjacent switch cabinets arranged in a row, causing the fire to expand again.

[0004] At present, after a fire occurs in the cable room of a switch cabinet, the substation operation and maintenance personnel can only know the fire when the fire spreads to the outside. Therefore, a fire monitoring system and control method are urgently needed to solve the above problems. Summary of the invention

[0012] Preferably, the step S1 specifically includes: collecting the amount of ultraviolet flame data in the cable room of the switch cabinet through an ultraviolet flame sensor element.

[0013] Preferably, the steps S2-S3 are specifically as follows: the collected amount of ultraviolet flame data is sent to a data processing module, and the data processing module compares the collected amount of data with a pre-stored data amount threshold. When the collected amount of data is greater than the threshold, it is recorded as data abnormality and is judged to trigger an alarm; when the collected amount of data is less than the threshold, it is recorded as data normal and is judged not to trigger an alarm.
