Description
Technical field
The invention belongs to a kind of electric line protection gold utensil, particularly a kind of anti-gold utensil of waving of Weight type power conversion that is installed on the aerial high voltage power transmission lead.
Background technology
Multiple disaster accident can take place because of the effect of natural conditions in overhead transmission line in the process of operation, threaten the safe and stable operation of circuit, overhead transmission line wave be wherein endanger bigger a kind of.Waving of overhead transmission line is a kind of air force wild effect; Be a kind of low frequency that under wind, causes behind the inhomogeneous icing of transmission line wire, the chattering of large amplitude; Also be that dynamic excitation makes the constantly result of accumulation of energy, in a span, have only one or a few half-wave showing as on the vibration shape.Wave the tension variation that has caused transmission pressure excessive, can produce many-sided harm transmission line.The lighter can cause flashover or tripping operation, and weight person then can cause disconnected strand of transmission pressure, break, goes offline, even shaft tower member, insulator string etc. are caused mechanical damage, and What is more, causes shaft tower to collapse, and causes great power grid accident.Wave accident from the circuit that China took place in recent years, the line voltage distribution grade until the 500KV accident of waving all has generation, has become a comparison of power industry distinct issues from 10KV.
Eliminate the global problem that waving of transmission line is the power transmission and distribution specialty, owing to people are confined to the solution problem of waving in the mechanics category always, so, never have desirable solution.At present, the mode that solves transmission line galloping has two kinds, and a kind of is to make it to avoid resonance point through the parameter that changes lead, for example, on lead, twines the anti-whip of waving, and the anti-gold utensils of waving such as swing wire clamp, revolution wire clamp, damping weight perhaps are installed on lead.The anti-gold utensil of waving of this type is gravitional force, elastic potential energy or the kinetic energy that the energy of lead swing temporarily is converted into gold utensil, it is not consumed, and the gold utensil energy stored also can act on the lead again; Also can be converted into the energy of waving of lead, belong to alternately conversion, that is to say with the form energy; The above-mentioned anti-gold utensil of waving just makes the kinetic energy circulation, and but can't it be weakened and eliminates, so; Prevent the poor effect of conductor galloping, perhaps just do not have the effect that prevents conductor galloping at all.Another kind is between out of phase lead, to install conductor spacer additional, utilizes out of phase lead to pin down each other, offsets energy.This method effect on low-voltage grade circuit is better, but for the voltage levels circuit, because phase spacing is excessive, thereby difficult installation, and the intensity of conductor spacer also is difficult to meet the demands, so, be not suitable on the circuit of voltage levels, using.
Summary of the invention
The technical problem that the present invention will solve is, overcomes that existing transmission line is anti-waves the not good problem of result of use that device exists, and provides a kind of scope of application wide, the anti-anti-gold utensil of waving of effective Weight type power conversion of waving.
The present invention includes framework, wire clamp main body and wire clamp pressing plate, the wire clamp main body is installed on the framework, and the wire clamp pressing plate is hinged on the wire clamp main body; Its special character is, energy conversion device is installed on framework, and described energy conversion device is made up of shell, coil, permanent magnetism sheet, bar, spring and weight; Coil is installed in the enclosure; The permanent magnetism sheet is installed on the bar, and is positioned at coil, and spring is installed on the bar; And be bearing in the bottom of permanent magnetism sheet, the consuming components that is connected with coil also is installed in energy conversion device.
The invention has the advantages that:
1, the present invention has changed the thinking of utilizing mechanics principle elimination transmission pressure to wave in the prior art; The mode of employing power conversion solves the problem of waving of transmission pressure; Through on the gold utensil framework, energy conversion device being installed, the kinetic energy on the transmission pressure is converted into electric energy, through consuming components power consumption is fallen again; Thereby the kinetic energy on the transmission pressure is thoroughly eliminated; And thoroughly destroyed the constantly process of accumulation of kinetic energy, and acutely waving of transmission pressure can't be taken place, really play the effect that transmission pressure is waved of eliminating.
2, parameter is convenient to adjustment, can adjust energy conversion device through changing coil, permanent magnetism sheet, spring and weight, and adaptability is strong; Range of application is wide, both has been applicable to low-voltage grade circuit, also is suitable for the voltage levels circuit; And simple in structure, be easy to suitability for industrialized production.
