Abstract
The utility model relates to a kind of wall-penetrating type current transformer, comprise instrument transformer body and the housing outside described instrument transformer body is set, be provided with in the both sides of described housing for hard-wired flange, described flange is fixed on the sidewall of described housing by securing member, dismountablely in the bottom of described housing is fixed with the fixed head with installing hole.Beneficial effect is: structure is simple, and stable performance, by being arranged on the flange of housing central section, make current transformer have effect through walls, Simultaneous Stabilization, the fixed head additionally by bottom can realize the back mounting structure of current transformer.
Description
Technical field
The utility model relates to current transformer technical field, especially relates to a kind of wall-penetrating type current transformer.
Background technology
Current transformer is the equipment measuring electric current, electric energy or relaying protection in power system switch cabinet; the semi-closed structure that the current transformer that current electric power system uses adopts iron core to expose; but in concrete application process; in order to save the space of switch cubicle; current transformer is needed to adopt semi-enclosed structure; the i.e. structure of wall-penetrating type; this structure is scarcely stable; install complicated; safeguard inconvenient; along with the prolongation of service time, its precision, insulation property all can decline, and become the hidden danger of equipment safety operation in electric power system.
Therefore, a kind of structure is simple, and the appearance of wall-penetrating type current transformer easy for installation is necessary.
Utility model content
The utility model provides a kind of wall-penetrating type current transformer, complicated to solve installation of the prior art, safeguards inconvenient problem.
The technical problem that the utility model solves realizes by the following technical solutions:
A kind of wall-penetrating type current transformer, comprise instrument transformer body and the housing outside described instrument transformer body is set, be provided with in the both sides of described housing for hard-wired flange, described flange is fixed on the sidewall of described housing by securing member, dismountablely in the bottom of described housing is fixed with the fixed head with installing hole.
As preferred technical scheme, the both sides of described housing are provided with the fixing hole of more than a group, in order to fixing described flange, realize the fixed installation of diverse location.
As preferred technical scheme, described flange is " Π " type structure, is provided with installing hole at the edge of described flange, so that fixedly mount with body of wall or cabinet.
As preferred technical scheme, described housing is also provided with mounting groove, and the position of described mounting groove is corresponding with fixing hole, so that location and firm described flange.
As preferred technical scheme, the width of rebate of described mounting groove and the thickness of flange match, to realize firm installation and to fix.
The beneficial effect that the utility model has is: structure is simple, stable performance, by being arranged on the flange of housing central section, makes current transformer have effect through walls, Simultaneous Stabilization, the fixed head additionally by bottom can realize the back mounting structure of current transformer.
Accompanying drawing explanation
In order to be illustrated more clearly in embodiment of the present invention or technical scheme of the prior art, be briefly described to the accompanying drawing used required in embodiment or description of the prior art below, apparently, accompanying drawing in the following describes is only embodiments more of the present invention, for those of ordinary skill in the art, under the prerequisite not paying creative work, other accompanying drawing can also be obtained according to these accompanying drawings.
Fig. 1 is the utility model: a kind of structural representation of wall-penetrating type current transformer;
