Abstract
The invention discloses a low-voltage current transformer box of a transformer. The box comprises a box cover and a box body, wherein the box cover is connected with the box body by a hinge; the interior of the box body is in a two-step shape from the top down; four wire outlet holes are formed in the front side surface of the box body at a first step; strip-type holes are formed in a length direction of the box body on the bottom surface of the box body at a second step; drainage grooves are formed on the two sides of the strip-type holes; a plurality of fixing clamps are arranged on the strip-type holes; drainage holes are formed in a side wall of the box body and corresponding to the drainage grooves; and a turnover angle of the box cover relative to the box body is 0-90 degrees. The box is convenient to mount, can prevent electricity larceny, and can be firmly and directly mounted on the transformer for use; wiring and routing of a current transformer and the transformer are facilitated; sleeves of the current transformer and the transformer have a safe distance; inspection of later personnel is facilitated; and the current transformer box can be effectively prevented from touching the transformer due to an excessive opening angle.
Description
Technical field
The present invention relates to a kind of dedicated box, particularly a kind of transformer low voltage current transformer case.
Background technology
At present, the overall structure of nearly all transformer low voltage current transformer case is all rectangle; And such body structure, if independent for instrument transformer is put in a chest, inconvenience is not only installed, operation is loaded down with trivial details, also there is the technical problem of not easily fixing this casing.Now, not only add the workload that metrological personnel installs this casing, but also the technical problem such as it is loaded down with trivial details to there is its installation procedure, and gage work efficiency is low.
Summary of the invention
The object of the invention is to the shortcoming and defect overcoming prior art, a kind of easy for installation, anti-electricity-theft, solid and reliable transformer low voltage current transformer case is provided.
The present invention is achieved through the following technical solutions:
A kind of transformer low voltage current transformer case, comprise case lid and casing, gemel connection is passed through between described case lid and casing, described box house is stepped in two-stage from top to bottom, and be provided with four wire holes in the positive side of the casing at the first ladder place, on the bottom surface of the second ladder place casing, the length direction along casing is provided with bar hole, bar hole both sides are provided with rhone, and bar hole is provided with multiple geometrical clamp; On wall box, corresponding rhone place offers osculum.
As preferably, described case lid is 0 ° ~ 90 ° relative to the flip angle of casing.
As preferably, described case lid and casing are provided with dead bolt that can be mutually adaptive.
As preferably, the sidewall of described casing is provided with ventilating opening.
As preferably, described geometrical clamp two ends are provided with bolt.
Transformer low voltage current transformer case of the present invention is step structure, and this casing, by being located at least 2 geometrical clamps at bar hole place, is clamped on the low-tension bushing of transformer, and each geometrical clamp is by the bolt at two ends fixing by casing.First ladder is to place instrument transformer, allows instrument transformer and be in same plane from the bushing shell for transformer that bar hole penetrates; Thus make the low tension wire of transformer just in time pass in this sleeve pipe and walk around the instrument transformer be in the first ladder plane; Wall box opens air port, is to be discharged by the heat in casing.When memory box has the rainwater of accumulation, the rainwater of this accumulation can also flow through rhone and flow out in this casing from osculum.Hinge makes case lid be 0 ° ~ 90 ° relative to the flip angle of casing, thus prevents that instrument transformer chest opening angle is excessive touches transformer.
Compared with prior art, the invention has the beneficial effects as follows: for the instrument transformer of encapsulated transformer low-tension current side, easy for installation, anti-electricity-theft, firmly can be directly installed on transformer and use, not only facilitate wiring and the cabling of instrument transformer and transformer, also the sleeve pipe of instrument transformer and transformer is allowed to have the distance of a safety, also facilitate the inspection of later stage personnel, effectively can prevent that instrument transformer chest opening angle is excessive touches transformer.
Accompanying drawing explanation
Below by embodiment, the invention will be further described by reference to the accompanying drawings.
Fig. 1 is the structural representation after the present invention opens;
Fig. 2 is the end view after the present invention closes;
10. case lid, 11. first dead bolts, 20. casings, 21. first ladders, 22. second ladders, 23. wire holes, 24. bar holes, 25. rhones, 26. osculums, 27. second dead bolts, 28. ventilating openings, 100. hinges.
Embodiment
As shown in Figure 1-2, transformer low voltage current transformer case, is comprised case lid 10, casing 20, is connected between case lid 10 with casing 20 by hinge 100.The connected mode of this hinge 100, can make case lid 10 be 0 ° ~ 90 ° relative to the flip angle of casing 20.Like this, case lid 10 would not encounter transformer in switching process, reduces the risk of the electric shock of staff.Simultaneously, this casing 20 is by being located at least 2 geometrical clamps (not shown) at bar hole 24 place, be clamped on the low-tension bushing of transformer, and casing 20 is fixed by the bolt at two ends by each geometrical clamp (not shown), casing 20 is inner stepped, is specially stepped in two-stage from top to bottom.Wherein, be provided with four wire holes 23 in the positive side of the casing 20 at the first ladder 21 place, the bottom surface of the casing 20 at the second ladder 22 place is provided with bar hole 24.Meanwhile, the both sides of bar hole 24 are also provided with rhone 25, and this groove is bent upwards into by casing 20 bottom edge of bar hole 24 both sides; On the sidewall of casing 20, corresponding rhone 25 also offers osculum 26.Stair-stepping design can allow instrument transformer and bushing shell for transformer be in same plane; Thus make transformer low tension wire out right through the instrument transformer be in the first ladder 21 plane, facilitate wiring and the cabling of instrument transformer and transformer, also allow the sleeve pipe of instrument transformer and transformer have the distance of a safety, also facilitate the inspection of later stage personnel.Secondly, the sidewall of casing 20 is also provided with ventilating opening 28, this ventilating opening 28 can dissipate the heat of savings in casing 20.
In order to prevent other people electricity filching behavior, therefore on case lid 10, be provided with the first dead bolt 11, corresponding, also on casing 20, be provided with the second dead bolt 27, so just can lock to the present invention, thus make casing 20 become enclosed type casing 20, avoid the generation of stealing situation.
In actual use, four bushings shell for transformer are deep in casing 20 through bar hole 24.Now, bushing shell for transformer just in time and be in instrument transformer in the first ladder 21 plane in same plane.Four of transformer low tension wires so just can be made directly to pass in corresponding bushing shell for transformer, and walk around corresponding instrument transformer, directly pass for user from corresponding wire hole 23.Wherein, casing 20, by two, three or four geometrical clamps (not shown), clamps bushing shell for transformer and be fixed, and each geometrical clamp (not shown) is undertaken gripping by the bolt at its two ends.When not needing to measure, by case lid 10 closing lid on casing 20, and at dead bolt 11, locking on 27 and carrying out closing keeping.
Above-described embodiment, just an example of the present invention, be not for limiting enforcement of the present invention and interest field, all technical schemes identical or equivalent with content described in the claims in the present invention, all should be included in scope.
