Abstract
The utility model relates to a protection device of a voltage transformer, in particular to a wire breakage alarm box of the voltage transformer. The box comprises a box body (1) and binding posts (2); a circuit board used for an alarm device is arranged in the box body (1); a binding groove (102) curved into the box body (1) is arranged in the side edge of the top face of the box body (1); and a plurality of the binding posts (2) are arranged in the binding groove. Therefore, problems that traditional binding posts exposed outside get wear and lines are easily loosened are effectively avoided.
Description
Technical field
The utility model relates to a kind of protective device of voltage transformer, specifically a kind of voltage transformer disconnection warning box.
Background technology
Voltage transformer be one with transformer unshakable in one's determination.It is mainly comprised of first and second coil, iron core and insulation; When applying a voltage U 1 on a winding, in iron core, just produce a magnetic flux φ, according to the law of electromagnetic induction, in secondary winding, just produce a secondary voltage U2; Change once or the number of turn of secondary winding, can produce different primary voltages and secondary voltage ratio, this just can form not voltage transformer on year-on-year basis; Voltage transformer in use can occur opening circuit because of life problems, easily to circuit, cause great damage, this warning box that just need to open circuit carries out breaking alarming, the binding post of traditional voltage transformer disconnection warning box exposes to box body conventionally, this just makes binding post very easily wear and tear, and makes wire lead drop out, and, traditional voltage transformer disconnection warning box exists and is difficult to fixing problem is installed, and uses extremely inconvenient.
Utility model content
In order to solve the problems of the technologies described above, the utility model provides a kind of voltage transformer disconnection warning box that stability is higher that uses.
The utility model is to solve the problems of the technologies described above adopted technical scheme to be: a kind of voltage transformer disconnection warning box, comprise box body and binding post, in box body, be provided with the circuit board for alarm device, in the side of box body end face is provided with, sink into the connecting groove of box body, in connecting groove, be provided with a plurality of binding posts.
In box body, being provided with circuit board, for surveying the break-make of circuit and sending signal, is existing apparatus, in connecting groove of the present utility model, sinks into box body, and this has just been avoided exposing to the binding post problem that comes off and make the difficult placement of box body easy to wear of box body.
And further, the middle part, bottom surface of box body is provided with mounting groove, mounting groove is parallel and isometric with an opposite side of bottom surface, a side of mounting groove be provided with two parallel and all perpendicular to the chute of mounting groove between mutually, another side is corresponding with chute is provided with the slot that is parallel to mounting groove, on box body, be also provided with clamp, one end of clamp is provided with rotating shaft, rotating shaft is arranged between two chutes, clamp can be slided along the length direction of chute, upset, clamp overturns along chute length direction, after slip, its fore-end is inserted in slot, during use, the corresponding site of voltage transformer is passed in the mounting groove of voltage transformer disconnection warning box, upset afterwards, promote clamp, the front end of clamp is inserted in slot, thereby realize fixing voltage transformer, while taking apart, only clamp need be extracted out, toward rightabout, promote afterwards, then upset retreats.
Four edges of described box body end face are equipped with location hole, and for box body is fixed on to correct position, binding post is provided with set bolt, after circuit is received on binding post, by set bolt, is fixed on binding post.
Beneficial effect: a kind of voltage transformer disconnection warning box of the utility model is arranged on connecting groove the side of box body and it is caved in, effectively avoided easily loosening problem of wearing and tearing, circuit that tradition exposes to the binding post of box body, and, in the utility model, the setting of the mounting groove of box bottom, chute and slot can make voltage transformer disconnection warning box conveniently be fixed on voltage transformer, convenient installation, dismounting and maintenance.
