The invention discloses a transmission line ice thickness monitoring system and a monitoring method thereof. The technical problem that ice thickness monitoring data is inaccurate in the prior art is solved. A tension sensor (3) is arranged on a cross arm (2) of a transmission tower (1). The lower end of the tension sensor (3) is connected with a suspension insulator string (5). The lower end of the suspension insulator string (5) is connected with a transmission conductor (6). A biaxial tilt sensor (4) is arranged at the joint of the tension sensor (3) and the suspension insulator string (5). A wind speed sensor (7) is arranged at the installation end of a line outer conductor side of the cross arm (2). A micro meteorological sensor (8) is arranged on the top end of the cross arm (2). The tension sensor (3), the biaxial tilt sensor (4), the wind speed sensor (7) and the micro meteorological sensor (8) are electrically connected with an industrial personnel computer (9). The practicability of the ice online monitoring system is improved effectively.
Description
technical field [0001] The invention relates to a monitoring system for the ice coating thickness of a transmission line, in particular to a monitoring system and a monitoring method for the ice coating thickness of a transmission line considering vertical wind loads. Background technique [0002] With the development of on-line monitoring technology for transmission lines, a large number of on-line monitoring devices for icing on transmission wires have been applied. The load of the rear tension sensor changes, so as to deduce the ice thickness of the wire. The calculation formula is as follows: [0003] ; [0004] The meaning of each parameter in the above equation is: D i is the equivalent ice thickness, T is the current tension value, θ is the angle between the current suspension insulator string and the vertical direction, s is the length of the line in the vertical span, ρ d is the linear density of the wire, g is the acceleration due to gravity, ρ b is the ice ...
