The plug type voltage transformer adopting the structure makes up the blank that no voltage transformer is suitable for an SF6 switch cabinet in the existing transformer markets, and the distribution cabinet is safe and reliable in running, besides, installation space for the plug type voltage transformer is reduced.
Description
Technical field
The utility model belongs to electrical equipment technical field, particularly relates to a kind of plug-type voltage transformer.
Background technology
Voltage transformer is a kind of special transformer that is defined structure and type of service.Usually be installed in various electric equipments or the Electric Appliance Cabinet as detecting element.The SF6(sulphur hexafluoride) switch cubicle is a kind of of Electric Appliance Cabinet, to compare the tool insulation effect good with general Electric Appliance Cabinet for it, and many advantages such as the cabinet volume is less, so the market demand of SF6 switch cubicle can be increasing, thereby can increase the market demand of the relevant electric equipment products that are applicable to this Electric Appliance Cabinet.Above-mentioned SF6 switch cubicle inside generally is provided with the inner cone socket, the high-pressure side of present widely used switch cubicle applied voltage instrument transformer is generally the circular terminal of protruding pour mass surface 2-5mm, this structure is not suitable for the SF6 switch cubicle and installs and uses, so be badly in need of a kind of voltage transformer that can rationally cooperate installation with the inner cone socket of SF6 switch cubicle of research and development.
Summary of the invention
The utility model provides a kind of simple in structure, plug-type voltage transformer that can accurately cooperate installation with the inner cone socket of SF6 for solving the technical problem that exists in the known technology.
The technical scheme that the utility model is taked for the technical problem that exists in the solution known technology is: a kind of plug-type voltage transformer, comprise the instrument transformer pour mass, it is characterized in that: the top of described instrument transformer pour mass is provided with cone, described instrument transformer pour mass is provided with inserts, pyramidal top is provided with screw, the instrument transformer plug is installed on the instrument transformer pour mass, described instrument transformer plug comprises ring flange, insulating case, one-time contact and spring, described ring flange is provided with slotted hole, described ring flange, insulating case and spring are sleeved on the instrument transformer pour mass by cone successively, the flange cover is by screw, slotted hole and inserts are fastening, and described one-time contact is connected with spring.
The utility model can also adopt following technical scheme:
Three slotted holes are arranged on the circumferencial direction of described ring flange, and the instrument transformer pour mass is provided with three inserts, and ring flange is fastening by three inserts of screw and instrument transformer pour mass.
Be sprayed with conductive aluminum coating and inferior light insulating varnish on the surface of described instrument transformer body.
Advantage and the good effect that the utlity model has are: because the utility model adopts technique scheme, promptly on the voltage transformer pour mass, be provided with inserts, described inserts is connected with ring flange, ring flange can be installed base plate with switch cubicle and reliably be connected, be earth potential, the assurance switch cubicle is safe and reliable to operation, and has reduced installing space.The instrument transformer plug is installed on the instrument transformer, and the instrument transformer plug comprises ring flange, insulating case, one-time contact and spring.The one-time contact of instrument transformer is connected by screw with inner cone socket in the switch cubicle.The voltage transformer of this structure has remedied the blank of existing instrument transformer market SF6 switch cubicle with voltage transformer.
Be sprayed with conductive aluminum coating and inferior light insulating varnish on the surface of described instrument transformer body, can play electric field shielding and oxidation resistant effect.
