Abstract

The utility model discloses a low-voltage current mutual inductor case body for a transformer, which comprises a shell, a top cap and a folder; and a rear wall of the shell is fixedly connected with a rear wall of the top cap; the low-voltage current mutual inductor case body for the transformer is characterized in that a strip-type hole is arranged in a bottom board of the shell; four outlet holes are arranged in a front panel of the shell; two fixed clips are arranged in a cavity of the shell; each fixed clip is fixed by fixing bolts at the two ends; the fixed clips clamp on a low-voltage bushing of a transformer; upper locking boards are fixedly arranged on the two side walls of the top cap; and lower locking boards matched with the upper locking boards are fixedly arranged on the two side walls of the shell. The low-voltage current mutual inductor case body for transformer has the advantages of small size, high intensity, convenient use and simple structure; as the low-voltage current mutual inductor case body for transformer is manufactured by a transparent material, the low-voltage current mutual inductor case body for the transformer is beneficial for checking the change of the low-voltage current mutual inductor and whether electricity is stolen or not. The low-voltage current mutual inductor case body for transformer is suitable for indoor and outdoor transformers.

Description

Transformer is used the low-voltage current mutual inductor box body

Technical field

The utility model relates to the high transformer case body special that supplies low meter, and a kind of specifically transformer is used the low-voltage current mutual inductor box body, is applicable to that industrial and mining enterprises, open air, remote mountain areas are directly installed on the transformer and use.

Background technology

During the existing transformer low voltage of China measures, be provided with low-voltage current mutual inductor, carry out low-temperature measurement through low-voltage current mutual inductor from the transformer low voltage outlet; Be to be placed on low-voltage current mutual inductor in the iron-clad metering antitheft case at present, prevent user's stealing, iron-clad metering antitheft case need be installed on the top cover of transformer; Need dismounting transformer closure stud earlier; Be fixed on the transformer with the casing of transformer closure stud with iron-clad metering antitheft case, its weak point is again: in work progress, owing to need dismounting transformer closure stud; So easy damage encapsulated coil; The easy leakage of oil of transformer also can scratch cable, has caused serious economy loss for power supply department and user.

Summary of the invention

The purpose of the utility model is to provide that a kind of volume is little, in light weight, intensity is high, easy to use, transparent, anti-electricity-theft, be directly installed on the transformer that uses on the transformer and use the low-voltage current mutual inductor box body.

In order to reach above purpose, the technical scheme that the utility model adopted is: this transformer is used the low-voltage current mutual inductor box body, comprises housing, top cover and folding; The rear wall of housing is fixedly connected with the rear wall of top cover through folding; It is characterized in that: on the base plate of housing, be provided with bar hole, on the front panel of housing, be provided with 4 wire holes, in the housing chamber, be provided with 2 geometrical clamps; Each geometrical clamp is fixed through the set bolt at two ends; Geometrical clamp is clamped on the low-tension bushing of transformer, on the two side of top cover, is fixed with upper lock plate, on the two side of housing, is fixed with the lower locking plate suitable with upper lock plate.

The utility model is also implemented through following measure: described housing two side is provided with louvre.

The beneficial effect of the utility model is: volume is little, intensity is high, easy to use, anti-electricity-theft, simple in structure, owing to adopt transparent material to process, helps checking the low-voltage current mutual inductor no-load voltage ratio and has or not the electric situation of theft, is fit to the indoor and outdoor transformer and uses.
