Abstract
The utility model discloses a coiling mold of a current transformer primary coil. The coiling mold of the current transformer primary coil comprises a coil panel, a U-shaped coiling moldboard is arranged at the top end of the coil panel, and an open mouth of the coiling moldboard faces toward the panel center of the coil panel. The coiling mold of the current transformer primary coil is simple in structure, convenient to manufacture, easy and quick to operate, and capable of enabling the primary coil to be formed and to be coiled on a secondary coil.
Description
Technical field
The utility model relates to a kind of winding mould, is specifically related to a kind of current transformer primary winding winding mould.
Background technology
In order to guarantee the power system security economical operation, must carry out monitoring and measuring to the ruuning situation of power equipment.But general measurement and protective device can not directly access high-tension apparatus No. one time; and the large electric current scaling transformation of primary system need to be become little electric current; supplying with measuring instrument and protective device uses; the effect of current transformer is to be converted to the less secondary current of numerical value to the larger primary current of numerical value by certain no-load voltage ratio; be used for protecting; the purposes such as measurement; the primary winding number of turn of current transformer seldom; to adopt thicker rigid line; being convenient to large electric current passes through; primary winding is on secondary coil; at present, people are directly twined primary winding at secondary coil, do not have fixing mould.
The shortcoming of prior art is: without mould, directly twine primary winding at secondary coil, can not well form the shape of primary winding, coiling has slowly been wasted a lot of time of workman.
The utility model content
Technical problem to be solved in the utility model is to provide a kind of formation primary winding shape, accelerates the current transformer primary winding winding mould of threading speed.
The technical solution of the utility model is as follows: a kind of current transformer primary winding winding mould, its key exists: comprise coil panel, be provided with horseshoe-shaped coiling template at described coil panel, the opening of described coiling template is towards described coil panel core, in primary winding, only secondary coil need be placed on the coil panel on the secondary coil thus, in the shape of a hoof coiling template, twine primary winding around template, just can well allow primary winding be shaped and on secondary coil, after winding, primary winding and secondary coil are upwards mentioned, and the primary winding that is shaped so just has been enclosed within secondary coil well mutually.
Described coiling template is welded on the described coil panel through column, fixes shape of a hoof template by column like this, and the shape of primary winding is better guaranteed when twining.
The described coil panel left and right sides is symmetrically welded with the coil retaining groove, the lower edge of described coiling template and the groove dike of coil retaining groove are in the same horizontal line, so fixedly secondary coil is on coil panel, so that more convenient in the time of primary winding, speed is faster.
Described coil panel lower surface is welded with fixed head, described fixed head is angle steel, and described fixed head one flanging is welded on described coil panel lower surface, and another flanging clamps through vice, this winding mould can be fixed on the vice like this, so that coiling time is more convenient.
The beneficial effects of the utility model are: the utility model is simple in structure, and is easy to make, simple to operate, quick, can be good at making primary winding to be shaped and is wrapped on the secondary coil.
Description of drawings
Fig. 1 is structural representation of the present utility model;
Fig. 2 is vertical view of the present utility model;
Fig. 3 is that the utility model is fixed on the structural representation on the vice 6.
Embodiment
The utility model is described in further detail below in conjunction with drawings and Examples:
Such as Fig. 1 and Fig. 2 and a kind of current transformer primary winding winding mould shown in Figure 3, comprise coil panel 1, be provided with horseshoe-shaped coiling template 2 on described coil panel 1 top, the opening of described coiling template 2 is towards described coil panel 1 core, described coiling template 2 is welded on the described coil panel through column 3, described coil panel 1 left and right sides is symmetrically welded with coil retaining groove 4, the lower edge of described coiling template 2 and the groove dike of coil retaining groove 4 are in the same horizontal line, described coil panel 1 lower surface is welded with fixed head 5, described fixed head 5 is angle steel, described fixed head 5 one ends are welded on described coil panel 1 lower surface, and the other end clamps through vice 6.
Although below by reference to the accompanying drawings preferred embodiment of the present utility model is described, but the utility model is not limited to above-mentioned embodiment, above-mentioned embodiment only is schematic rather than determinate, those of ordinary skill in the art is under enlightenment of the present utility model, under the prerequisite of the utility model aim and claim, can make and representing like the multiple types, as: the shape of coiling template, position etc.; The fixing such conversion such as mode of coil panel all fall within the protection range of the present utility model.
