Abstract

The utility model relates to a wide-band falling type isolator fault indicating device, mainly composed of a connecting arc ring 1, an isolator 2, a clamping ring 4, a fuse wire 7, a fuse wire box 9, etc. The connecting arc ring 1 and the clamping ring 4 are supported and fixed into one body by four isolators 2. The fuse wire box 9 is fixed on the clamping ring 4 by a support frame 5. The fuse wire 7 and a conducting bar 8 are installed in the fuse wire box 9. The left end of the fuse wire 7 is fixed on a falling indicating plate 10 through a screw bolt 11. The right end of the fuse wire 7 is fixed on the right side wall of the fuse wire box 9 by a screw bolt 6. The conducting bar 8 and a support bar 13 are fixed into one body. The lower end of the support bar 13 is fixed on the connecting arc ring 1. The lower end of the falling indicating plate 10 is connected to the lower part of the left side wall of the fuse wire box 9 by a hinge 12.

Description

Wide-band drop off type isolator fault indicator

The utility model is a kind of broadband drop type insulator breakdown indicator of used for transmission line.

The insulator of transmission line of electricity requires all can reliability service under atmospheric over-voltage, internal overvoltage and long-time running voltage.But owing to act on when being deposited on bad weather condition such as the filthy particulate of solid on the insulator surface, liquid or gas and mist, dew, rain, ice or snow melt, to the electrical strength of insulator be reduced, thereby make the insulator of transmission line of electricity not only may under superpotential effect, flashover take place, more frequent is under long-time running voltage pollution flashover to take place, and causes power outage.The flashover vestige often is capped behind the insulator arc-over, causes the track walker not see the burning trace of flashover insulator, searches the trouble spot to line walking and brings difficulty, often need to step on the tower line walking, fault is got rid of slow, and labor strength is big, and people are are constantly researching and developing accident indicator for this reason.Existing " shaft tower fault detector " and " insulator arc-over indicator " operational effect are all not ideal enough, " shaft tower fault detector " complex structure, the accurately localization of faults; The straight line pole that " insulator arc-over display " can only be used for heavy current grounding system uses, and can not show the insulator breakdown hidden danger of scaling loss when flashover current is no more than action current.Still find no and the same or analogous record of the utility model through consulting patent documentation and interrelated data.

The purpose of this utility model provide a kind of simple in structure, with low cost, be active in one's movements reliable, the electrical network of each electric pressure of 10-500KV broadband all applicatory drop type insulator breakdown indicator.

The utility model is realized as follows:

Broadband drop type insulator breakdown indicator, mainly by connecing loop-drive 1, insulator 2, snap ring 4, compositions such as fuse 7 and fuse block 9, connecing loop-drive 1 is integral with four insulator 2 support fixation of snap ring 4 usefulness, fuse block 9 usefulness supports 5 are fixed on the snap ring 4, fuse 7 and contact rod 8 are housed in fuse block 9, fuse 7 left ends are fixed to by bolt 11 and fall on the indicator board 10, right-hand member is fixed on the right side wall of fuse block 9 with bolt 6, contact rod 8 is fixed into one with support bar 13, the lower end of support bar 13 is fixed on and connects on the loop-drive 1, and the lower end of falling indicator board 10 is connected to the left side wall bottom of fuse block 9 with hinge.Fuse block 9 left and right sidewalls are provided with the hole that fuse 7 is passed through, and front end box wall is provided with the hole that contact rod 8 is passed through.Fall on the indicator board 10 and the corresponding hole that fuse 7 is passed through that is provided with of the left side wall of fuse block 9.

The utility model has the advantages that: simple in structure, with low cost, be active in one's movements reliable, indicating fault is accurate, the electrical network of each electric pressure of 10-500KV is all applicable.

Fig. 1 is a main TV structure synoptic diagram of the present utility model;

Fig. 2 is a plan structure synoptic diagram of the present utility model.

Introduce embodiment of the present utility model with reference to the accompanying drawings:

As shown in the figure, it is very easy that the utility model is implemented, and connecing loop-drive 1 is to make with copper wires, and snap ring 4 can adopt metal book plate to make, and is used to support and is connected the insulator 2 that connects loop-drive 1 and snap ring 4 and can makes with pottery or other insulating material.Fuse block 9 adopts insulating sheet material to make.Fall indicator board 10 and adopt metal book plates to make, with fuse block 9 left side wall corresponding surfaces on scribble red instruction markings.When the utility model uses, snap ring 4 is enclosed within on the insulator steel cap and fastening with bolt 3, according to electric pressure coupling fuse 7, fuse 7 left ends are secured to and fall on the indicator board 10, right-hand member is fastened on the right side wall of cut-out case 9, must guarantee to make fuse 7 compress contact rod 8 simultaneously.When insulator arc-over takes place when, electric current is passed to fuse 7 and makes its fusing through connecing loop-drive 1, support bar 13 and contact rod 8, falling indicator board 10 falls and overturns, make indicator board 10 be hung on the fuse block 9 under the effect of hinge 12 and exposing cue mark, the track walker also can see cue mark clearly in place far away, thereby can take measures as early as possible, discharge fault, make transmission line of electricity operate as normal as early as possible.
