Description

A kind of open type transformer

Technical field

It the utility model is related to open type transformer technical field, and in particular to a kind of open type transformer.

Background technology

Open type transformer is mainly used in distribution system transformation project, easy for installation, also can band without a bus is torn open It is electrically operated, client's normal electricity consumption is not influenceed, is saved human and material resources, financial resources for user's transformation project, is improved efficiency.The series is mutual Sensor can support the use with relay protection, measurement and metering device.

Upper and lower iron core, is typically screwed on shell by existing open type transformer on the market, assembling Personnel need fixed screw, and so installation is inconvenient, while waste of manpower, material resources and time.

Also, easily produce and loosen in the course of work in use, iron core closes up and down in conventional open type transformer, Data are inaccurate caused by causing, and influence measurement accuracy.

Utility model content

The purpose of this utility model is to overcome above-mentioned the deficiencies in the prior art, and the technology for solving presently, there are lacks Fall into, the utility model provides a kind of open type transformer.

Technical scheme is used by the utility model：

A kind of open type transformer, including upper shell, lower house, upper core and lower core, the upper core are installed on Enclosure interior, the upper core and upper casing body by integral forming, the lower core are installed on inside lower house, and the lower core is with Housing is integrally formed, and the upper shell and the hinge connection of described lower house one end, the upper shell other end are provided with a protrusion, institute State lower house opposite position and protrude the hasp being engaged with described provided with one.

Further, the folding angle of the upper shell and lower house is 180 °.

Further, the hasp is hypotenuse, is easy to hasp to clasp protrusion.

The beneficial effects of the utility model are：A kind of open type transformer, easy for installation disclosed in the utility model, without Carry out iron core dismounting, installation, can hot line job, do not influence client's normal electricity consumption, for user's transformation project save manpower, thing Power, financial resources, improve efficiency.The utility model open type transformer can with relay protection, measurement and metering device are supporting makes With.

The utility model is described in further detail below in conjunction with the accompanying drawings.

Brief description of the drawings

Fig. 1 is the closure state structural representation of the utility model open type transformer.

Fig. 2 is the open mode structural representation of the utility model open type transformer.

Fig. 3 is the side structure schematic view of the utility model open type transformer.

In figure, 1- upper shell 2- lower house 3- upper core 4- lower cores 5- protrusion 6- hasps.

Embodiment

In order to deepen, to understanding of the present utility model, the utility model to be made with reference to the accompanying drawings and examples further detailed Thin explanation.Following examples are only used for clearly illustrating the technical solution of the utility model, and can not be limited with this The scope of protection of the utility model.

As shown in figure 1, the utility model open type transformer, including upper shell 1, lower house 2, upper core 3 and lower core 4, upper core 3 is installed on inside upper shell 1, and upper core 3 is integrally formed with upper shell 1, and lower core 4 is installed on inside lower house 2, Lower core 4 is integrally formed with lower house 2, and upper shell 1 and one end hinge connection of lower house 2, the other end of upper shell 1 are provided with a protrusion 5, the opposite position of lower house 2 is provided with a hasp 6 being engaged with protrusion 5.

As shown in Fig. 2 the folding angle of upper shell 1 and lower house 2 is 180 °.

Open type transformer on the market is typically all that upper and lower iron core is screwed on shell, is so installed not It is convenient.As shown in Figure 1-2, upper and lower iron core is directly installed in housing by the utility model, and iron core is integrally formed with housing, without Carry out the installation of iron core.

As shown in figure 3, the utility model open type transformer, protrusion can be square or rectangular, have one on hasp Through hole, through hole is in the same size with protrusion, buckles hasp, protrudes and blocks hasp right through through hole, and upper and lower iron core closure is not easy Loosen, measurement accuracy is controllable.

It is noted that embodiment described above is to the illustrative and not limiting of technical solutions of the utility model, affiliated skill The equivalent substitution of art field those of ordinary skill or other modifications made according to prior art, as long as not new beyond this practicality The thinking and scope of type technical scheme, it should be included within the interest field required by the utility model.
