Abstract
The utility model relates to an arrangement for indicating the short-circuit of power equipment, mainly comprising a magnetic conductive clip 8, a housing 11 and a glass tube 5. The glass tube 11 is filled with butanol discolored liquid, dark red discolored powder of ferric oxide, and a magnetic conductive ball 3; a magnetic conductive plate 2 and the magnetic conductive clip 8 are arranged inside the housing, and the magnetic conductive plate 2 and the magnetic conductive clip 8 can form a closed magnetic circuit. The utility model has the advantages of simple structure, convenient installation and operation. A duplexure in which a short-circuit fault occurs can be rapidly and conveniently detected in an electric network.
Description
The utility model relates to the electric network fault indicator, specifically a kind ofly is used to indicate the power equipment short-circuit current indicator of current failure position of being short-circuited in the electrical network.
Major loop and duplexure thereof are generally arranged, several at least tens even a hundreds of duplexure at most in the major loop in the existing electric power networks.Major loop all can be provided with the protective relaying device of short-circuit current, and this is necessary.Its short circuit current protection is all adjusted 2.5～3 times that must conform with this major loop rated current; it will undertake its 2.5～3 times of duplexure rated current summation in other words; and except that major loop and important duplexure; most of duplexures all are not provided with the protective relaying device (especially 600A and following duplexure) of short-circuit current, and the size of short-circuit current also can't be known (expense because of the short-circuit current protective relaying device that duplexure is set is higher) in moment.Like this, bigger short-circuit current appears in certain duplexure one, protective relaying device one action of major loop, and the some duplexures in the whole major loop will interruption of power supply.Existing technology is that duplexure is checked guilty culprit one by one.Duplexure is many more, and inspection certainly will expend a large amount of time and efforts, and causes the large tracts of land power failure, and power supply is very worthless for modern city for this.
The utility model is exactly the problem at above-mentioned existence, a kind of duplexure and zone that can show the electric current that is short-circuited rapidly is provided, be convenient in time inquire about and fix a breakdown, in time recover the power equipment short-circuit current indicator of the line powering except that the fault branch loop.
The utility model mainly is made up of magnetic conduction folder 8, glass tube 5 and housing 11.Wherein, glass tube 5 seals, and butanols class variable color liquid 6 and di-iron trioxide variable color powder 4 and magnetic conduction ball 3 are equipped with in its inside, and glass tube 5 is positioned at housing 11.In the front of housing 11 view window 1 is arranged, be used for the variation in the sight glass pipe 5.Magnetic conduction folder 8 is ring texturees, and cable or bus-bar penetrate wherein, and its two is separately fixed on the inside surface of glass tube 5 middle parts two side bodies 11.Two are drawn magnetic sheet 2 and lay respectively at both sides, glass tube 5 bottom magnetic conduction and press from both sides on the inside surface of 8 lower case 11.What housing 11 adopted is non-magnet material, and what draw that magnetic sheet 2, magnetic conduction folder 8 and magnetic conduction ball 3 all adopt is soft magnetic material.Magnetic conduction presss from both sides 8, draws the magnetic circuit of magnetic sheet 2 and magnetic conduction ball 3 formation one sealing.
Principle of work of the present utility model is such, when normally passing through rated current by the power circuit work in the magnetic conduction folder 8, because there is above-mentioned closed magnetic path in the utility model, therefore, the magnetic attraction deficiency that rated current produced action by this power circuit so that magnetic conduction ball 3 makes progress, also just can not stir variable color powder 4 and variable color liquid 6, the variable color powder precipitation is in glass tube 5 bottoms, the color of variable color liquid 6 be infuse clearly transparent; When breaking down, power circuit produces when being higher than the short-circuit current of rated current numerical value, this short-circuit current produced magnetic attraction moment just can attract magnetic conduction ball 3 to quicken to scroll up in glass tube 5, mixes and variable color with variable color liquid 6 thereby stir variable color powder 4.Can know rapidly that from the variable color depth degree this power circuit is the road fault that is not short-circuited.
In case after being arranged in variable color liquid 6 variable colors of glass tube 5, this color can keep 2～4 hours, people are enough to find out the ruuning situation of the some duplexures of major loop during this period of time, the unshorting fault zone.During this period of time, this liquid is replied again to infusing transparent color (because variable color powder 4 precipitate gradually) clearly, and the utility model is simple in structure, operates easy for installationly, reliable, is specially adapted to monitor the safe operation of power equipment and power circuit.
Specify the utility model embodiment below in conjunction with accompanying drawing.
Fig. 1 is the utility model front view.
Fig. 2 is the left view of figure.
Fig. 3 is the vertical view of Fig. 1.
In Fig. 1 to Fig. 3, magnetic conduction folder 8 is by two ring texturees of partly forming, be hinged with movable axis 9 between this two part, on magnetic conduction folder 8 screw 12 that two attached cables are used be housed, two of magnetic conduction folder 8 lays respectively at two inboards of housing 11, and be fixed on the housing 11 with bolt 10, glass tube 5 seals, and it is positioned at housing 11, and a loam cake 7 is arranged at the top of housing 11, be used for fixing glass tube 5, butanols class I liquid I and wine-colored ferric oxide powder are housed in glass tube 5.Magnetic conduction ball 3 of the present utility model, magnetic conduction folder 8 and draw magnetic sheet 2 and all adopt rimming steel to make, housing 11 adopts plastics to make.
When present embodiment uses, two of magnetic conduction folder 8 is partly opened by movable axis 9, the cable or the bus-bar of duplexure in the electrical network are penetrated wherein, fixing with screw 12 again magnetic conduction folder 8 two inboards of being inserted in housing 11, fixing with bolt 10, installment work just by finishing, can be known the liquid of seeing in the glass tube 5 from the view window 1 in housing 11 fronts like this, thereby whether the work of determining this duplexure is normal.
