Conductor galloping suppression system of power transmission line and control method of conductor galloping suppression system

Abstract

The invention discloses a conductor galloping suppression system of a power transmission line. The conductor galloping suppression system comprises a power transmission line conductor, a machine caseand a horizontal suppression block; the horizontal suppression block is in mechanical connection with the machine case through an L-shaped connecting arm a; a perpendicular suppression block is in mechanical connection with the machine case through an L-shaped connecting arm b; a rectangular through hole a with a horizontal length of 2d and a perpendicular length of d is formed in the middle of the horizontal suppression block; a rectangular through hole b with a horizontal length of d and a perpendicular length of 2d is formed in the middle of the perpendicular suppression block, wherein d isthe diameter of the power transmission line conductor; the power transmission line conductor passes through the rectangular through hole a and the rectangular through hole b; a horizontal suppressiontransmission apparatus is arranged between the horizontal suppression block and the machine case; and a perpendicular suppression transmission apparatus is arranged between the perpendicular suppression block and the machine case. The conductor galloping suppression system controls the position of the power transmission line conductor to be stable for preventing galloping; and in addition, by virtue of a monitoring system of the apparatus, the conductor state can be monitored in real time.

Description

technical field [0001] The invention relates to a transmission line suppressing conductor galloping system and a control method thereof, and belongs to the technical field of wind prevention and disaster reduction for transmission lines. Background technique [0002] Galloping of transmission line conductors is a serious disaster that endangers the safe and stable operation of transmission lines. It is a low-frequency, large-amplitude self-excited vibration generated by eccentric ice-coated conductors under wind excitation, often causing flashover trips, hardware and insulators Serious accidents such as damage, wire breakage, broken bolts, tower material damage, foundation damage, and even tower collapse. Among the natural disasters that trigger power systems, wind disasters are the most serious. Statistics show that 70% of the faults in the power system are caused by the collapse of transmission towers under the action of strong winds and the ice-coated dancing of ground w...

Problems solved by technology

[0008] The technical problem to be solved by the present invention is: to design a transmission line suppressing wire galloping system and its control method to solve the problem that the prior art transmission line restraining wire galloping cannot avoid the area where galloping easily occurs; increase the current to prevent or melt the wire Ice coating, limited by operating conditions, will affect the life of the wire insulation layer; to limit the range of wire galloping, use wire arrangement and change the size of the tower head, not only the cost is high, but also the wire galloping cannot be actively suppressed

Using mechanical methods such as spacers to gallop is limited in scope of application and the anti-gallop effect is not ideal
