Abstract
An indoor dry-type combined transformer relates to a combined transformer, and comprises a voltage transformator, a current transformator, a primary leading-out terminal and a secondary leading-out terminal which are casted to form a whole body by using ethoxyline. The indoor dry-type combined transformer is characterized in that a phase A, a phase B and a phase C of the primary leading-out terminal are cable sockets which can be used in conjunction with cable plugs with identical current carrying capacity. Because the primary leading-out terminal adopts the cable sockets, the connection is convenient; the primary leading-out terminal adopts the cable socket type, so that the primary leading-out terminal is closed after the cable plugs are inserted into the cable sockets so as to lead the integral structure to be compact and reduce the integral size.
Description
Technical field
The utility model relates to a kind of instrument transformer, refers more particularly to a kind of combination transformer.
Background technology:
The dry type combination transformer is that mutual induction of voltage and electric current mutual inductance are integral with poured with epoxy resin, thus have that easy maintenance, resistant are dirty, humidity, have do not have oily, fire-retardant, UV resistant, ageing-resistant, mechanical strength advantages of higher.The subject matter that mainly exists has at present: the primary connection end is the exposed output of copper bar, and needs the electric clearance of assurance greater than regulation between housing, take up room during use, and stealing or electric shock easily; Primary connection end and secondary leading-out terminal all adopt traditional securing member connected mode when wiring, the wiring trouble.
The utility model content
The purpose of this utility model is the deficiency that overcomes prior art, and the indoor dry type combination transformer of a kind of compact conformation, easy-to-connect is provided.
The technical scheme that technical problem adopted that solves is:
Indoor dry type combination transformer comprises mutual induction of voltage, electric current mutual inductance, leading-out terminal, secondary leading-out terminal, mutual induction of voltage, electric current mutual inductance, leading-out terminal, a secondary leading-out terminal are integral with poured with epoxy resin, A, B, the C three-phase that it is characterized in that a leading-out terminal be can be identical with ampacity the matching used cable socket of cable plug; Cable socket is the truncated cone-shaped structure, comprises contact rod and epoxy resin layer, and the contact rod center has the circular hole of band internal screw thread, and epoxy resin layer closely wraps in the periphery of contact rod.
The beneficial effects of the utility model are: because a leading-out terminal adopts cable socket, easy-to-connect; A leading-out terminal is the cable socket formula, and after pegging graft with cable plug, one time leading-out terminal is closed, and makes compact overall structure, has dwindled overall dimensions.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified:
Fig. 1 is the front view of the utility model embodiment;
Fig. 2 is the vertical view of the utility model embodiment.
Among the figure 1, cable socket 2, secondary leading-out terminal 3, main body 4, fuse 11, epoxy resin layer 12, contact rod 13, internal screw thread
Embodiment:
At Fig. 1, among Fig. 2, indoor dry type combination transformer main body 3 is an epoxy resin poured body, comprise mutual induction of voltage, the electric current mutual inductance, a leading-out terminal, the secondary leading-out terminal, mutual induction of voltage, the electric current mutual inductance, a leading-out terminal, the secondary leading-out terminal is integral with poured with epoxy resin, the bottom of main body 3 is a secondary leading-out terminal 2, the A of a leading-out terminal, B, the C three-phase be can be identical with ampacity the matching used cable socket 1 of cable plug, cable socket 1 is the truncated cone-shaped structure, comprise contact rod 12 and epoxy resin layer 11, contact rod 12 centers have the circular hole of band internal screw thread 13, and epoxy resin layer 11 closely wraps in the periphery of contact rod 12.
During use, a leading-out terminal is a cable socket 1, the supporting use of cable plug that is complementary with contact rod 12 internal screw threads 13 of cable socket 1, after cable plug revolves the internal screw thread 13 that is plugged into torch 12, one time leading-out terminal is closed, and makes compact overall structure, has dwindled overall dimensions.
Claims (2)
1, indoor dry type combination transformer comprises mutual induction of voltage, electric current mutual inductance, leading-out terminal, secondary leading-out terminal, mutual induction of voltage, electric current mutual inductance, leading-out terminal, a secondary leading-out terminal are integral with poured with epoxy resin, A, B, the C three-phase that it is characterized in that a leading-out terminal be can be identical with ampacity the matching used cable socket of cable plug.
2, indoor dry type combination transformer according to claim 1 is characterized in that above-mentioned cable socket is the truncated cone-shaped structure, comprises contact rod and epoxy resin layer, and the contact rod center has the circular hole of band internal screw thread, and epoxy resin layer closely wraps in the periphery of contact rod.
