Abstract
The utility model belongs to the technical field of electric power accessories, and discloses a current transformer terminal block protective cover. The current transformer terminal block protective cover is mainly characterized by comprising a cover body, the lower portion of the cover body is provided with a trunking, the upper portion of the cover body is provided with a horizontal through hole, the top end of a ribbon which penetrates through the though hole is provided with a ribbon head, the tail end of the ribbon is provided with a sealed end. When the current transformer terminal block protective cover is used, a cover body of the protective cover is covered on a connected terminal of a transformer, and then the ribbon is wrapped tightly around the bottom of a pour body of the transformer, and next the sealed end portion of the tail end of the ribbon is additionally provided with a seal, and finally the redundant ribbon is cut out. A terminal block can be effectively protected after being additionally provided with the protective cover, electricity stealing action of people through a short-circuit terminal or a loose terminal block is avoided, and meanwhile dust cannot cover the terminal after the protective cover is used, a measuring negative error because of short circuit of two transformer terminal blocks caused by damping of the dust is avoided, and measuring accuracy is guaranteed. The current transformer terminal block protective cover is simple in structure, low in cost and convenient to mount.
Description
Technical field
The utility model belongs to electric power accessory technical field, relates in particular to a kind of current transformer connecting terminal protective cover.
Background technology
At present, what the most of distribution transformer low-pressure side metering of rural power grids was often used is 3 LZM type current transformers and 3 single-phase electric energy table packs, except over the past two years LZM type current transformer manufacturer has been equipped with the binding post protective cover, most of operating LZM type current transformer does not have the terminal guard shield, binding post and secondary connection expose outside, leave opportunity to electricity filching person, while is because of environmental impact and the distribution box sealing problem of infield, very easily make the binding post place cover dust, the dust rear formation shorting stub of making moist causes error in dipping to increase.
The utility model content
The technical problem that the utility model solves just provides the current transformer connecting terminal protective cover that a kind of pair of wire connection terminals provides effective protection.
For solving the problems of the technologies described above, the technical solution adopted in the utility model is: comprise that the bottom is provided with the cover body of wire casing, the top of described cover body has cross through hole, and through hole is passed with the band of pricking head in the top, and the end of band has sealing.
When the current transformer connecting terminal protective cover that the utility model provides uses, first the protective cover cover body is covered the instrument transformer terminal of wiring, then band was tightened around instrument transformer pour mass bottom in one week, then installed additional seal at the terminal sealing of hole of band place, cut off at last unnecessary band and get final product.Binding post can access effective protection after installing protective cover additional, prevent that artificial short-circuited terminal or loosening binding post from carrying out electricity filching behavior; Simultaneously, use protective cover after dust can not cover terminal, avoided the metering negative error of making moist and causing short circuit two wire connecting terminal of transformers to cause because of dust, guarantee metering accuracy.The current transformer connecting terminal protective roof structure that the utility model provides is simple, with low cost, easy for installation.
Description of drawings
Fig. 1 is the structural representation of the utility model current transformer connecting terminal protective cover.
Embodiment
Be described further below in conjunction with the structure of accompanying drawing to the utility model current transformer connecting terminal protective cover.
As shown in Figure 1, the utility model current transformer connecting terminal protective cover comprises cover body 1, and cover body 1 is provided with wire casing 2, and cover body 1 top has cross through hole 3, and through hole 3 is passed with a band 5 of pricking 4 in the top, and the end of band 5 has sealing 6.
When the current transformer connecting terminal protective cover that the utility model provides uses, first protective cover cover body 1 is covered the instrument transformer terminal of wiring, then band 5 was tightened around instrument transformer pour mass bottom in one week, then install seal additional at band 5 terminal sealing of holes 6 places, cut off at last unnecessary band 5 and get final product.Binding post can access effective protection after installing protective cover additional, prevent that artificial short-circuited terminal or loosening binding post from carrying out electricity filching behavior; Simultaneously, use protective cover after dust can not cover terminal, avoided the metering negative error of making moist and causing short circuit two wire connecting terminal of transformers to cause because of dust, guarantee metering accuracy.
Protection range of the present utility model not only is confined to above-described embodiment, as long as structure is identical with the utility model current transformer connecting terminal protective roof structure, just drops on the scope of the utility model protection.
Claims (1)
1. current transformer connecting terminal protective cover, comprise that the bottom is provided with the cover body of wire casing, is characterized in that: the top of described cover body has cross through hole, and through hole is passed with the band of pricking head in the top, and the end of band has sealing.
