Abstract

The utility model relates to a positioner of a radio fault testing instrument for high voltage transmission lines, which comprises a radio fault testing instrument and a positioner which makes the radio fault testing instrument hung on the high voltage transmission line, and the positioner and the radio fault testing instrument perform together the action of an iron core of a transformer. The utility model mainly comprises anchor ears, an anchor ear seat, an anchor ear torsion spring, a press line torsion spring, a torsion spring shaft and a pad wire plate; the press line torsion spring presses a power line on the pad wire plate and performs the action of suspension positioning, the anchor ear torsion spring presses closely the upper ends of two anchor ears to form a closed iron core, and if the press line torsion spring and the anchor ears are pulled apart, the installation and disassembly can be conveniently conducted. The utility model has the advantages of simple structure, reliable performance, electrified operation, etc., and the utility model can be widely used for electric lines.

Description

Ultra-high-tension power transmission line radio failure tester steady arm

The utility model relates to a kind of instrument that utilizes the principle detection high-tension line fault of mutual inductor, particularly this instrument can be suspended on easily the locating device on the hi-line, belongs to electrical measurement or electric power transportation art.

The electric power of big power station is when carrying at a distance, in order to reduce line loss, all take to improve the way of carrying voltage, at present, electric power carries voltage up to the hundreds of kilovolt, safety in order to ensure transmission line of electricity is very important, a kind of ultra-high-tension power transmission line radio failure tester is arranged, be installed on the hi-line, utilize the principle of current transformer, with hi-line is a winding, annular core is housed on tester, on iron core, be wound with Secondary Winding again, can judge this line powering situation by the induced potential that detects Secondary Winding, again the signal that detects being become high-frequency signal is launched by antenna, so just can monitor the working condition of this place's circuit by received signal in the pulpit at a distance, advantage with remote monitor, but the iron core of current transformer need be enclosed within on the line of electric force in this instrument, present way be by hand directly with iron core sleeve on hi-line, for safety, when installation or removal, all must under situation about having a power failure, carry out, so very inconvenient, even can cause large-area power failure, give power supply and all can cause unnecessary loss with electric unit.

The purpose of this utility model is in order to overcome the weak point of above-mentioned tester, designs a kind of rational in infrastructure, dependable performance, easy to use, ultra-high-tension power transmission line radio failure tester steady arm that can charged loading and unloading.

Ultra-high-tension power transmission line radio failure tester steady arm of the present utility model comprises the radio failure tester and tester is suspended on the ultra-high-tension power transmission line and plays the steady arm of transformer iron core effect, this steady arm comprises left and right anchor ear, left and right anchor ear seat, left and right anchor ear torsion spring, left and right line ball torsion spring, left and right torsion axis and a pad line plate, wherein, the lower end of left side anchor ear and the upper end of left anchor ear seat and left anchor ear torsion spring, left line ball torsion spring all are sleeved on the left torsion axis, and left anchor ear torsion spring is pressed in the upper left limit of left anchor ear; The lower end of right anchor ear and the upper end of right anchor ear seat and right anchor ear torsion spring, right line ball torsion spring all are sleeved on the right torsion axis, and right anchor ear torsion spring is pressed in the top right-hand side of right anchor ear; A pad line plate is installed between the left and right anchor ear seat, and left and right line ball torsion spring is pressed on the pad line plate.

Accompanying drawing 1 is the structural representation of steady arm of the present utility model;

Accompanying drawing 2 is left view or right views of accompanying drawing 1.

Referring to accompanying drawing, 1 among the figure is left and right anchor ear, the 2nd, and left and right anchor ear torsion spring, the 3rd, left and right line ball torsion spring, the 4th, left and right torsion axis, the 5th, left and right anchor ear seat, the 6th, screw, the 7th, pad line plate, the 8th, box body.A left side wherein, a right anchor ear 1 and a left side, right anchor ear seat 5 constitutes the first half iron core of mutual inductor, using cold-reduced sheet titanizing or cold-reduced sheet chromium plating or stainless steel or other permeability magnetic material makes, a left side, right anchor ear can be respectively around a left side, right torsion axis 4 rotates, a left side, the upper end of right anchor ear is installed in a left side, left side on the right torsion axis 4, right anchor ear torsion spring 2 compresses closing together, pad line plate 7 usefulness screws 6 are contained in a left side, between the right anchor ear seat, a left side, right line ball torsion spring 3 is pressed on the pad line plate, pad line plate can be made with bakelite plate or other insulating material, the middle part and the hi-line position contacting of pad line plate 7 can be made " V " font, a left side, the lower end of right anchor ear seat 5 is stretched in the box body 8 and is connected with the Lower Half iron core of the mutual inductor that is wound with Secondary Winding.During installation, left side with steady arm, right line ball torsion spring makes progress cocked and drives a left side, right anchor ear outwards rotates and opens, put into a special strut and from top to bottom the line ball torsion spring is pulled to both sides with hook, just can make an iron core-closed big mouth of having opened from the top, lift strut, with line of electric force from a left side, continue to go up after dropping on the pad line plate after the opening part of right anchor ear passes and lift, steady arm is moved downward by pressure, make the line ball torsion spring leave the strut hook, the torsion of line ball torsion spring is pressed in line of electric force on the pad line plate, and tester can be suspended on the line of electric force, simultaneously, the torsion of anchor ear torsion spring is also with a left side, the upper end of right anchor ear compresses closing again together, and it is iron core-closed that the iron core of opening is become again, finished the installation task.As long as steady arm is pulled down,, all do not influence the duty of line of electric force during installation and removal when taking off when the torsion of pulling force greater than line ball torsion spring and anchor ear torsion spring can take off steady arm from line of electric force with strut yet.

The utlity model has simple and reasonable, dependable performance, can charged installation or dismounting, easy to operate etc. Advantage can be extensive use of at ultra-high-tension power transmission line.
