Alarm device for water entering cable interlayer

Abstract

The invention discloses an alarm device for water entering a cable interlayer. The alarm device comprises detectors which are used for detecting water levels of water entering the cable interlayer and generating an acquired voltage value when the water levels reach a preset water level threshold value, and an alarm signal generator which is connected with the detectors and is used for generating an alarm signal according to the acquired voltage and reporting the alarm signal to a monitoring end of a master station. The alarm device can remotely alarm water entering the cable interlayer; besides, different water levels are reported and alarmed through a plurality of detectors, convenience is brought to technicians to monitor environmental conditions of different transformer substations or switching stations, and effects of improving the detection efficiency and reducing the human cost are achieved.

Description

technical field [0001] The invention relates to the field of electric power, in particular to an alarm device for water ingress in a cable interlayer. Background technique [0002] At present, due to environmental problems and severe weather, the impact on power supply facilities is increasing. Water in the cable interlayer in substations, switching stations and other stations may bring hidden dangers to the safe and reliable power supply in the region. Power supply facilities immersed in water for a long time There may be a risk of reduced reliability. For example, when the severe weather intensifies, it often brings unexpected serious impacts. When the rainstorm strikes, it is often because the rainwater floods the cable interlayer in the substation, switching station and other stations, and the power supply equipment is affected. However, in view of this situation, at present, the investigation can only be carried out through daily manual inspections and special inspecti...

Problems solved by technology

[0002] At present, due to environmental problems and severe weather, the impact on power supply facilities is increasing. Water in the cable interlayer in substations, switching stations and other stations may bring hidden dangers to the safe and reliable power supply in the region. Power supply facilities immersed in water for a long time there may be a risk of reduced reliability

For example, when the severe weather intensifies, it often brings unexpected serious impacts. When the rainstorm strikes, it is often because the rainwater floods the cable interlayer in the substation, switching station and other stations, and the power supply equipment is affected.

However, in view of this situation, at present, it can only be checked through daily manual inspections and special inspections in severe weather. There is no related type of device in the prior art to monitor and alarm the water ingress

[0003] Moreover, under the current conditions, if you want to know whether there is rainwater backflow in the cable interlayer in the station, you can only judge through equipment failure and manual inspection. There is no function of prediction and prevention, and the workload of the staff is virtually increased.

[0004] Aiming at the problem that the water ingress of the cable interlayer in the station cannot be monitored and alarmed in related technologies, no effective solution has been proposed so far
