Abstract
The utility model discloses an anti-theft device of an oil-immersed transformer, which relates to the technical field of transformer manufacture. The anti-theft device of the oil-immersed transformer comprises anti-theft bolts, a box cover and box edges, and is characterized in that: the four special anti-theft bolts are arranged at joints of the box edges and the four corners of the box cover of the oil-immersed transformer, anti-theft washers are arranged in installation, and then the anti-bolts are locked by a spherical wrench. Under the situation that the production cost is almost not increased, the anti-theft device well plays an anti-theft role of an inside device body of the transformer, thereby electrical equipment of users is effectively protected, the safety and reliability of power supply of the users are met, and the safe use of electricity of the users in production and lift is ensured to maximum extent.
Description
Technical field:
The utility model relates to technical field of transformer manufacturing, relates in particular to a kind of anti-theft device for transformer simple in structure, safe and reliable, easy-to-use.
Background technique:
The oil immersed transformer of domestic production at present, case lid connects with all adopting common M12 or M16 bolts such as (GB5782) being connected of fuel tank case edge.In recent years, because the electrolytic copper price is constantly soaring, many law-breakers promptly utilize this common bolt connecting mode of transformer, steal the inner copper coil of transformer easily, thereby sell when copper scrap after its coil removed and obtain illicit income, this criminal offence brings serious consequence for vast user, produces enormous economic loss.
The model utility content:
In order to address the above problem, the utility model provides a kind of anti-theft device for transformer simple in structure, safe and reliable, easy-to-use.
The technological scheme that adopts of the present utility model is: a kind of anti-theft device of oil immersed transformer, comprise case lid, case edge and anti-theft bolt, described anti-theft bolt be fixed on case along with the joint at four angles of case lid; Described anti-theft bolt comprises anti-theft screw cap and anti-theft nut, and the top of described anti-theft screw cap is provided with the nut skewed slot, and a sidewall of described nut skewed slot is perpendicular to plane on the nut, and another sidewall rises from the bottom land spiral; Described anti-theft nut is provided with the nut skewed slot, and a sidewall of described nut skewed slot is perpendicular to the nut top plane, and another sidewall rises from the bottom land spiral.
One sidewall of described nut skewed slot spiral in the direction of the clock rises, and a sidewall of described nut skewed slot spiral in the direction of the clock rises.
One sidewall of described nut skewed slot is by spiral rising counterclockwise, and a sidewall of described nut skewed slot rises by the counter clockwise direction spiral.
Described nut skewed slot have two at least, described nut skewed slot has two at least.
Described nut skewed slot have three, described nut skewed slot has three.
The size of described nut skewed slot is greater than the size of described nut skewed slot.
The beneficial effects of the utility model are: a kind of simple in structure, safe and reliable, easy-to-use anti-theft device is provided; under the situation that does not almost have to improve at cost of production; well played the antitheft effect of the inside device body of transformer; thereby protected user's power equipment effectively; guarantee Security, reliability that the user powers, guaranteed that to greatest extent the user is producing and safety utilization of electric power in life.

Fig. 2 is a mounting structure schematic representation of the present utility model;
Fig. 3 is the structural representation of anti-theft screw cap of the present utility model;
Fig. 4 is the structural representation of anti-theft nut of the present utility model.
Embodiment:
For technological means, creation characteristic that the utility model is realized, reach purpose and effect is easy to understand, below in conjunction with concrete diagram, further set forth the utility model.
As shown in Figure 1, 2, a kind of anti-theft device of oil immersed transformer, comprise that anti-theft bolt 1, case lid 6 and case are along 5, respectively the case of transformer along 5 with the joint at four angles of case lid 6, adopt the anti-theft bolt 1 of the special use of four Gent systems, pad is gone up Anti-theft washer 4 during installation, with special-purpose spanner it is locked again.Anti-theft bolt 1 comprises anti-theft screw cap 2 and anti-theft nut 3.
Shown in Fig. 3,4, the top of anti-theft screw cap 2 is provided with nut skewed slot 21, and a sidewall of described nut skewed slot 21 is perpendicular to plane on the anti-theft screw cap 2, and another sidewall rises from the bottom land spiral; Described anti-theft nut 3 is provided with nut skewed slot 31, and a sidewall of described nut skewed slot 31 is perpendicular to anti-theft nut 3 top plan, and another sidewall rises from the bottom land spiral.If a sidewall of nut skewed slot 21 spiral in the direction of the clock rises, a then sidewall of nut skewed slot 31 spiral rising in the direction of the clock.Spiral rises if a sidewall of nut skewed slot 21 is pressed counterclockwise, and then a sidewall of nut skewed slot 31 is by spiral rising counterclockwise.Described nut skewed slot 21 have two at least, described nut skewed slot 31 has two at least, and is preferred, all selects three for use.The size of described nut skewed slot 31 is greater than the size of described nut skewed slot 21.
Case lid 6 is with after case is connected along 5, by the spanner and the special-purpose anti-theft bolt 1 of special use, and tightly interlock rotation of anti-theft nut 3, thus with its locking, after screwing, use common wrench can't open case lid, thereby play good antitheft effect.
More than show and described basic principle of the present utility model, major character and advantage of the present utility model.The technician of the industry should understand; the utility model is not restricted to the described embodiments; that describes in the foregoing description and the specification just illustrates principle of the present utility model; under the prerequisite that does not break away from the utility model spirit and scope; the utility model also has various changes and modifications, and these changes and improvements all fall in claimed the utility model scope.The claimed scope of the utility model is defined by appending claims and equivalent thereof.
