Embodiment Construction

[0015] as attached figure 1 As shown, the present invention includes a sleeve 4 fixedly connected to the lifting ear I1, a pressing plate 8 arranged at one end of the sleeve 4, a climbing skirt 6 arranged around the sleeve 4, and a permanent magnet 5 arranged on the inner wall of the sleeve 4 , the pull rod 9 set in the sleeve 4 and fixedly connected to the lifting ear II 10 and the coil 3 set on the pull rod 9 .

[0016] Lifting lug I1 and lifting lug II10 are fixedly connected to different wires respectively. Sleeve 4, climbing skirt 6 and tie rod 9 are usually made of non-metallic materials. The function of climbing skirt 6 is to increase the creepage distance and prevent discharge along the surface; the sleeve The cavity 2 formed by 4 and the pressure plate 8 is provided with a damping liquid, and the pull rod 9 set in the sleeve 4 is set with a spring 7. The function of the damping liquid is to increase resistance and heat dissipation, which can prevent the coil 3 from ov...

Abstract

The invention relates to a protection tool using a power protection transmission line, in particular to a device for preventing a conductor from dancing and producing damage to an iron tower. The device comprises a sleeve fixedly connected with a lifting lug I, a pressure plate arranged at one end of the sleeve, a creepage extending skirt arranged around the sleeve, a permanent magnet arranged onthe inner wall of the sleeve, a pull rod sleeved in the sleeve and fixedly connected with a lifting lug II and a coil arranged on the pull rod, wherein the coil cuts magnetic force lines in the permanent magnet, and eddy current is produced in the coil so as to produce heat. The generation of the eddy current blocks the relative motion of the conductor connected with the device, and plays a role in consuming the kinetic energy of the conductor.

Description

technical field [0001] The invention relates to a protection tool used for electric power protection transmission lines, in particular to a device capable of preventing the dancing of power transmission wires and protecting iron towers from being damaged. Background technique [0002] Under certain meteorological conditions, the wires that transmit power will continue to act on the vibration system formed by the wires and the iron tower, and the wires will dance. The dancing of the wires is a kind of energy. The iron tower, the iron tower and the wire constitute a vibration system. The vibration system forms resonance and forced vibration under the continuous action of wind energy, forming the galloping of the transmission line, and the galloping will become larger and larger as time goes on. On the one hand, the galloping energy destroys the structure of the iron tower, on the other hand, it will form a short circuit discharge between phases or towers due to galloping. The ...
