An icing sensor and an icing detection method based on the difference between air and ice resistance characteristics

Abstract

The invention discloses an icing sensor based on the difference between air and ice resistance characteristics. The icing sensor includes an icing perception sensor, the icing perception sensor is connected with a digitalization processing electric circuit, the electric circuit includes a master control chip and an A / D conversion module, the master control chip includes a reset module, a RTC timing module, a data storage module, a voltage conversion module and a data communication module, and the icing perception sensor is connected with the master control chip through the A / D conversion module. The invention also discloses an icing detection method, the method includes the following steps: the icing sensor is installed on a power transmission conducting wire, the signal is sent to the master control chip through a data monitoring background, the master control chip controls contact point pairs and temperature sensors to measure the resistance value and temperature of the position of each contact point, the medium of the position of the contact point is determined according to the obtained resistance value and temperature, then the medium of the position of the contact point is sent to the data monitoring background, the icing shape is drafted by the data monitoring background, and the icing thickness is calculated. The problem that the icing thickness and shape of the line cannot be accurately monitored by the icing monitoring technology is solved.

Description

technical field [0001] The invention belongs to the technical field of ice coating measurement of power transmission lines, and relates to an ice coating sensor and an ice coating detection method based on the difference in resistance characteristics between air and ice. Background technique [0002] Under freezing rain or ice and snow conditions, the icing of suspended transmission lines, fixed towers of high-voltage transmission lines, offshore drilling platforms, surfaces of buildings or various equipment, suspended supports, branches, etc. can often cause huge disaster consequences. At the beginning of 2008, southern my country encountered a rare ice and snow disaster. The continuous freezing rain made many power transmission wires and towers covered with ice with a thickness of 50-100mm, which greatly exceeded the technical standard for bearing ice thickness of general power transmission networks, resulting in The collapse of electric towers and the large-scale paralysis...
