Abstract
The utility model relates to a mutual-inductor insulator structure for gas insulated switch cabinet, which is characterized in that a bulge for fixing a secondary connecting terminal is arranged on the installation surface of a mutual-inductor insulator, a recessed connector and an annular seal groove are arranged on the external installation surface of the bulge with a certain interval, and a seal ring is embedded in the seal groove. The mutual-inductor insulator structure for gas insulated switch cabinet has the characteristics that the structural design is reasonable and simple, thereby being convenient for the wiring of the secondary terminal outside a gas chamber, and the seal structure is arranged on the insulator, thereby leading the installation to be faster and more convenient and the sealing effect to be excellent.
Description
Technical field
The utility model relates to a kind of electric component, particularly has sealing function, can carry out secondary connection again outside air chamber, gas insulation switch cabinet instrument transformer insulator structure safe in utilization, convenient, reliable.
Background technology
The instrument transformer that the SF6 inflating switch cabinet uses, its insulator adopts mostly that resin is integrated poured to form, insulator surface is provided with once and the secondary connection terminal, need be arranged on because of instrument transformer in the air chamber of sealing, wiring for convenience, the secondary connection terminal need expose outside the switch cubicle air chamber, and secondary terminal and switch cabinet have certain insulation distance and assurance that the insulation level of certain value is arranged, and each switch cubicle all will carry out the processing of profiling hollow out at the shape and the shared area at instrument transformer secondary connection terminal position.Simultaneously, also the cabinet wall of requirement installation instrument transformer has the plane of the indeformable wall thickness structure of rigidity and certain precision, and to guarantee the sealing between cabinet wall and the instrument transformer, installation, use make things convenient for inadequately.
Summary of the invention
It is a kind of easy to install and use that the utility model purpose is to provide, the gas insulation switch cabinet of good sealing effect instrument transformer insulator structure.
Technical solution of the present utility model is: a kind of gas insulation switch cabinet instrument transformer insulator structure, the installed surface that it is characterized in that the instrument transformer insulator is provided with the fixedly projection of secondary connection terminal, be provided with setting-in connector and annular seal groove at regular intervals on the outside installed surface of projection, groove is embedded with sealing ring.In order to help sealing, the seal groove top of built-in sealing ring is a little more than installed surface, and after product was installed, the gas in the gas compartment can not guarantee that sealingly secure is reliable to external leaks.
The utility model is to be provided with a little more than its surperficial crowning on the installed surface of instrument transformer insulator, and the secondary connection terminal is arranged on the projection, after insulator is fixing, both has been convenient to secondary connection, can guarantee certain insulation distance again, can not expose excessive simultaneously.Hermetically-sealed construction is set on insulator, makes to seal by the easier for installation of insulator and switch cubicle reliable.
Characteristics of the present utility model are: reasonable in design, simple, make things convenient for of the wiring of secondary terminal in the air chamber outside, on insulator, hermetically-sealed construction is set, make easier for installation quick, good sealing effect.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Embodiment
The utility model is described in further detail below in conjunction with accompanying drawing:
As shown in the figure, the gas insulation switch cabinet that the utility model provides can be the insulator of current transformer or voltage transformer with the instrument transformer insulator structure, insulator 5 adopts the poured with epoxy resin moulding, ironcore choke is arranged in the insulator, the outside has one, the secondary connection terminal, its shape can be designed to its installed surface 6 as required and be any solid geometry shape on plane, the middle part of installed surface is provided with projection 3, be fixed with a plurality of secondary connection terminals 4 on the crowning, being provided with the setting-in connector at regular intervals on the outside installed surface of projection is embedded nut 1, on installed surface, also be provided with the seal groove 2 that is looped around the connector outside, the top of seal groove is a little more than installed surface, and it is embedded with sealing ring.
