Abstract

The invention discloses a fiber-grating-based power transmission line iron tower deformation on-line monitoring device. The fiber-grating-based power transmission line iron tower deformation on-line monitoring device comprises a monitoring center, a substation and a monitoring terminal, wherein the substation and the monitoring terminal are connected with the monitoring center in sequence. The monitoring terminal comprises a plurality of fiber grating strain sensors. The fiber grating strain sensors are connected with a fiber grating demodulator in the substation through an OPGW. A fiber grating inclination sensor group is also connected with the fiber grating demodulator. The fiber grating inclination sensor group is connected with the fiber grating demodulator in the substation through an OPGW. The fiber grating demodulator is connected with a detection host. The detection host is also connected with a microclimate sensor. The problem that tiny deformation of an iron tower cannot be accurately monitored through an existing detection method is solved. The invention also discloses a monitoring method of the fiber-grating-based power transmission line iron tower deformation on-line monitoring device.

Description

technical field [0001] The invention belongs to the field of state monitoring of power transmission and transformation equipment, and relates to an on-line monitoring device for the deformation of a power transmission line iron tower based on an optical fiber grating, and also relates to a monitoring method of the monitoring device. Background technique [0002] During the construction of the operating line, the transmission line inevitably passes through special areas such as soft soil areas, hillsides, and riverbeds. Coupled with the influence of natural factors such as hurricanes, ice, earthquakes, and various human factors, it is easy to cause the tower to break down. Deformation, causing problems such as insulator strings and ground wire clips moving, and insufficient electrical safety distance. When the problem expands, it is easy to cause accidents such as tripping, tower collapse and disconnection. The deformation of the iron tower is a typical "invisible fault", whi...
