Power box water inflow monitoring protection device through relative dielectric constant detection

Abstract

The invention discloses a power box water inflow monitoring protection device through relative dielectric constant detection. The device structurally comprises a protective cover, a device shell, a protective door, an installation frame, an intelligent monitoring device and a handle frame, wherein the protective door is arranged on the front end face of the device shell, and the protective door and the device shell are in clearance fit; the intelligent monitoring device is arranged inside the device shell, and the intelligent monitoring device and the device shell are fixedly connected; the installation frame is located on the rear end face of the device shell, and the installation frame and the device shell are connected together in a welded mode; the protective cover is perpendicular tothe protective door and is fixedly installed at the right end of the protective door; and the handle frame is in left-and-right parallel with the protective cover and is fixed to the front surface ofthe protective door in a mechanical installation mode. The device achieves the purposes that whether water flows inside can be monitored directly and stably by monitoring internal dielectric constantchanges, and strain of internal water inflow is quickly realized through current changes.

Description

technical field [0001] The invention relates to the field of water inflow monitoring devices, in particular to a water inflow monitoring and protection device for electric power boxes through relative permittivity detection. Background technique [0002] The water inflow monitoring device of the power box refers to the real-time monitoring system used for the daily use of the power box in the outside world, but the existing water inflow monitoring device: [0003] 1. During the monitoring work, ultrasonic waves are usually used as the medium to monitor the water flow entering the power box through sound waves, but the ultrasonic waves will vibrate the water flow when propagating, so that the water flow may disperse into the interior of important devices, and Ultrasonic waves are easily blocked during transmission and recovery, making the detection results inaccurate. [0004] 2. At the same time, during the monitoring work, it is necessary to process the data when the ultra...

[0003] 1. During the monitoring work, ultrasonic waves are usually used as the medium to monitor the water flow entering the power box through sound waves, but the ultrasonic waves will vibrate the water flow when propagating, so that the water flow may disperse into the interior of important devices, and Ultrasonic waves are easily blocked during transmission and recovery, making the detection results inaccurate

[0004] 2. At the same time, during the monitoring work, it is necessary to process the data when the ultrasonic wave rebounds to make the alarm light flash and to perform alarm work at the same time. The alarm device cannot quickly alarm at the moment of water ingress, and usually there is no Set up a timely filling large resistance device to prevent the continuous supply of current and stop the operation of the equipment, thereby increasing the potential safety hazard of the equipment
