Abstract
The utility model discloses an open type current transformer, which comprises a circular transformer main body with a through hole, wherein the circular transformer main body consists of two semicircular transformer main bodies; a plurality of radially and inwards protruded elastic rubber rings integrated with the inner wall of the through hole are arranged on the inner wall of the through hole; support ribs are arranged in the elastic rubber rings; one end of each support rib is connected with the inner wall of the through hole, and the other end of each support rib is connected with the inner wall of the corresponding elastic rubber ring; the two ends of each elastic rubber ring are shaped like bell mouths; fixed bumps are arranged on the middle parts of the elastic rubber rings; the fixed bumps, the support ribs and the elastic rubber rings are integrated. According to the open type current transformer, the phenomenon that the service life of the open type current transformer is shortened by the deformation of the elastic rubber rings can be effectively prevented, and the open type current transformer is convenient to mount and low in manufacturing cost.
Description
Technical field
The utility model relates to a kind of instrument transformer, and more particularly, it relates to a kind of Open Type Electric Current Mutual Inductor.
Background technology
Current transformer is large electric current scaling transformation on power equipment can be become to a kind of device of little electric current, supplies with measuring instrument and protective device and uses, and the ruuning situation of power equipment is carried out to monitoring and measuring, guarantees power system security economical operation.Open Type Electric Current Mutual Inductor in the market, comprise the ring-shaped shell with perforation, the hole wall of described perforation be provided with some and its one, radially to the elastic rubber ring of inner process, for being clamped on wire or the cable of all size, whole current transformer need not be fixed by base.But elastic rubber ring use for a long time can make elastic rubber ring distortion, and Open Type Electric Current Mutual Inductor can not be fixedly secured on cable, reduce Open Type Electric Current Mutual Inductor useful life.
Utility model content
The deficiency existing for prior art, the purpose of this utility model is to provide a kind of Open Type Electric Current Mutual Inductor, has long service life, is convenient to the feature of installation, low cost of manufacture.
For achieving the above object, the utility model provides following technical scheme: a kind of open type
Current transformer, comprise the circular current transformer body with perforation, described circular current transformer body is comprised of two semicircular ring-type current transformer body, described perforation inwall is provided with some and its one, radially to inner process elastic rubber ring, in described elastic rubber ring, be provided with brace rod, described brace rod one end is connected with perforation inwall, the other end is connected with elastic rubber ring inwall, described elastic rubber ring two ends are bell mouth shape, in the middle of described elastic rubber ring, be provided with fixedly projection, described fixedly projection, brace rod and elastic rubber ring are integrated, described brace rod thickness and elastic rubber ring wall thickness half, described fixedly projection is one, it is shaped as hemisphere.
By adopting technique scheme, described elastic rubber ring inwall is provided with brace rod, can greatly reduce elastic rubber ring because extruding causes distortion, described elastic rubber ring two ends are bell mouth shape, in the middle of described elastic rubber ring, be provided with fixedly projection, increase between Open Type Electric Current Mutual Inductor and cable and coordinate fastness, can effectively prevent that elastic rubber ring distortion from causing Open Type Electric Current Mutual Inductor to reduce useful life, be convenient to install low cost of manufacture.
Accompanying drawing explanation
Fig. 1 is the structural representation of the Open Type Electric Current Mutual Inductor of the utility model embodiment;
Fig. 2 is that Fig. 1 structural representation is at the cutaway view of A-A direction.
In figure 1, circular current transformer body; 2, perforation; 3, elastic rubber ring; 4, brace rod; 5, fixing projection.
Embodiment
Referring to figs. 1 through Fig. 2, a kind of Open Type Electric Current Mutual Inductor of the utility model is described further.
A kind of Open Type Electric Current Mutual Inductor, comprise the circular current transformer body 1 with perforation 2, described circular current transformer body 1 is comprised of two semicircular ring-type current transformer body, described perforation 2 inwalls are provided with some and its one, radially to inner process elastic rubber ring 3, wherein said elastic rubber ring 3 is three and to be evenly distributed on perforation the most suitable on 2 inwalls, in described elastic rubber ring 3, there is brace rod 4, described brace rod 4 be elastic rubber ring 3 wall thickness half, described brace rod 4 one end are connected with perforation 2 inwalls, the other end is connected with elastic rubber ring 3 inwalls, described elastic rubber ring 3 two ends are bell mouth shape, in the middle of described elastic rubber ring 3, be provided with a fixedly projection 5, fixedly the quantity of projection can increase to two or more according to elastic rubber ring 3 physical lengths, described fixedly projection 5, brace rod 4 is integrated with elastic rubber ring 3.
Described elastic rubber ring 3 inwalls are provided with brace rod 4, can greatly reduce elastic rubber ring 3 because extruding causes distortion, in the middle of described elastic rubber ring 3, be provided with fixedly projection 5, increase between Open Type Electric Current Mutual Inductor and cable and coordinate fastness, can effectively prevent that elastic rubber ring distortion from causing Open Type Electric Current Mutual Inductor to reduce useful life, be convenient to install low cost of manufacture.
