Intelligent security system for power outage detection of transformer substation

Abstract

The invention discloses an intelligent security system for a power outage detection of a transformer substation, and relates to the technical fields of transformer substation monitoring in a power grid system and intelligent security. The intelligent security system comprises a server, an intelligent terminal, a monitoring module, a power outage detector, a magnetic door stopper detector, an infrared detector, a wind detector, a wireless communication module, and an intelligent power supply module. The wind detector is located inside the transformer substation; the power outage detector, the magnetic door stopper detector, the infrared detector, and the wind detector are separately connected to the monitoring module and to realize one-way communication; the monitoring module is connected to the internet through the wireless communication module; the server and the intelligent terminal communicate with each other through the internet; and the intelligent power supply module is electrically connected to the monitoring module and the wireless communication module separately. According to the intelligent security system for the power outage detection of the transformer substation, thesystem realizes the power outage monitoring and the security protection of the unattended transformer substation through technologies of automatic control, and the like.

Description

technical field [0001] The invention relates to the technical field of grid system substation monitoring and intelligent security, in particular to an intelligent security system for substation power failure detection. Background technique [0002] At present, the 35kV substation under the jurisdiction of the county company is now handed over to the city company to take over. In fact, the key in the substation is lost on the actual site, and there are cases in the substation where outsiders enter the substation without the permission of the operation and maintenance management personnel. Uneven, UPS and other devices lack the power failure alarm function. When the AC power failure in the station, the protection device and communication device in the station will be directly powered by the battery and cannot upload the AC power failure signal. When the battery in the station is fully discharged, it will The power failure of the protection device of the substation may cause se...

[0002] At present, the 35kV substation under the jurisdiction of the county company is now handed over to the city company to take over. In fact, the key in the substation is lost on the actual site, and there are cases in the substation where outsiders enter the substation without the permission of the operation and maintenance management personnel. Uneven, UPS and other devices lack the power failure alarm function. When the AC power failure in the station, the protection device and communication device in the station will be directly powered by the battery and cannot upload the AC power failure signal. When the battery in the station is fully discharged, it will The power failure of the protection device of the substation may lead to serious accidents such as leapfrog action and communication interruption

[0003] Through the summary of previous faults, it is found that unattended substations are prone to cause foreign objects rolled up by strong winds to fall on electrical equipment and cause short-circuit grounding when unattended substations encounter severe weather with local strong winds, and blow into the protection room to cause malfunction or refusal of protection devices, etc. series of hazards
