Description
Technical field
The utility model relates to voltage transformer, particularly relates to a kind of elbow-type plug-type band cable fuse voltage transformer.
Background technology
Voltage transformer is the transformer of a ribbon core.It is primarily of primary winding, secondary coil, iron core and insulation composition.The operation principle of voltage transformer is identical with transformer, and basic structure is also iron core and former and deputy winding, has the advantages that capacity is very little and more constant, close to Light Condition during normal operation.The impedance of voltage transformer itself is very little, once circuit is short-circuited, sharp increase is burnt coil by electric current.For stopping coil burnout phenomenon, the primary side of voltage transformer is connected to fuse, and when there is line fault, fuse can fuse in time, carries out available protecting to voltage transformer.
But common voltage transformer is when changing fuse, needs first top terminal to be dismantled, then just can take out change of fuse, bother very much; Meanwhile, existing voltage transformer primary side insulation effect is poor, easily occurs connecting obscission simultaneously.
Utility model content
The purpose of this utility model is to provide a kind of elbow-type plug-type band cable fuse voltage transformer, can with join elbow-type plug with the use of, insulation effect is good, has change of fuse conveniently advantage simultaneously.
The utility model adopts following technical proposals:
A kind of elbow-type plug-type band cable fuse voltage transformer, comprise the setting up and down fuse housing being hollow and voltage transformer housing, fuse housing and voltage transformer housing mutual conduction, primary winding is provided with in described voltage transformer housing, secondary coil and iron core, described fuse housing comprises connecting portion and is arranged at the elbow-type socket of both sides, connecting portion rear end, elbow-type socket is the truncated cone-shaped of horizontally disposed hollow, the inner chamber of elbow-type socket is fuse storage chamber, fuse is arranged in fuse storage chamber, the front end of fuse is electrically connected with jockey rear end by the first spring, jockey front end is electrically connected with the primary winding in voltage transformer housing, the rear end of fuse is directly connected with the metal struts of joining in elbow-type plug, described fuse housing and voltage transformer housing are structure as a whole and by epoxy resin vacuum moulding by casting.
Described jockey comprises primary winding joint pin and is fixed on the movable clamp in the middle part of primary winding joint pin, movable clamp is arranged in the inner chamber of connecting portion, the intracavity inner surface of connecting portion is also provided with guide vane end stop, be provided with the second spring between guide vane end stop and movable clamp front surface, the front end of primary winding joint pin is electrically connected with the primary winding arranged in voltage transformer housing by wire; First spring housing is located on the primary winding joint pin on rear side of movable clamp.
Described elbow-type socket outer surface is provided with rubber ring.
Described movable clamp is insulation activity clamp.
The utility model is by arranging elbow-type socket as fuse storage chamber separately, there is good insulation effect, and fuse is arranged in fuse storage chamber, utilize the first spring to realize fuse two ends to be connected with the metal struts of joining in elbow-type plug and the reliable of jockey, also be convenient to take out fuse from elbow-type hub trailing end opening easily after taking off elbow-type plug simultaneously, and without the need to by inserts, connecting line and a terminal all take off to be changed again, the utility model can with join elbow-type plug with the use of, there is change of fuse conveniently advantage.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the vertical view of Fig. 1.
Embodiment
Below in conjunction with drawings and Examples, the utility model is done with detailed description:
As depicted in figs. 1 and 2, elbow-type plug-type band fuse 4 voltage transformer described in the utility model, comprise fuse housing and the voltage transformer housing 1 of hollow, fuse housing and voltage transformer housing 1 mutual conduction and fuse housing body is positioned at above voltage transformer housing 1, fuse housing and voltage transformer housing 1 are structure as a whole and by epoxy resin vacuum moulding by casting.Primary winding, secondary coil and iron core is provided with in voltage transformer housing 1, fuse housing comprises connecting portion 2 and is arranged at the elbow-type socket 3 of both sides, connecting portion 2 rear end, elbow-type socket 3 is the truncated cone-shaped of horizontally disposed hollow, the inner chamber of elbow-type socket 3 is fuse storage chamber, fuse 4 is arranged in fuse storage chamber, the front end of fuse 4 is electrically connected with jockey rear end by the first spring 5, jockey front end is electrically connected with the primary winding in voltage transformer housing 1, and the rear end of fuse 4 is directly connected with the metal struts of joining in elbow-type plug.
The movable clamp 7 that jockey comprises primary winding joint pin 6 and is fixed in the middle part of primary winding joint pin 6, movable clamp 7 can adopt insulation activity clamp 7.Movable clamp 7 is arranged in the inner chamber of connecting portion 2, the intracavity inner surface of connecting portion 2 is also provided with guide vane end stop 8, be provided with the second spring 9 between guide vane end stop 8 and movable clamp 7 front surface, the front end of primary winding joint pin 6 is electrically connected with the primary winding arranged in voltage transformer housing 1 by wire 10; First spring 5 is sheathed on the primary winding joint pin 6 on rear side of movable clamp 7.
In use, fuse 4 is positioned in fuse storage chamber, to join elbow-type plug is again inserted on elbow-type socket 3, metal struts now in elbow-type plug is by the rear end of immediate roof at fuse 4, and the front end of fuse 4 is then electrically connected with the primary winding in voltage transformer housing 1 by jockey.First spring 5 provides pressure to the front end of fuse 4 all the time, can ensure that fuse 4 two ends can remain reliable with the metal struts of joining in elbow-type plug and jockey respectively and be connected on the one hand, be convenient on the other hand to take out fuse 4 from elbow-type socket 3 open rearward end easily after taking off elbow-type plug.And when the first spring 5 lost its bounce cannot recover initial length, the second 9, spring can replace the first spring 5, ensure that fuse 4 two ends are connected with the metal struts of joining in elbow-type plug and the reliable of jockey; When fuse 4 length changed is less, the second spring 9 also can ensure that fuse 4 two ends are connected with the metal struts of joining in elbow-type plug and the reliable of jockey.In order to prevent elbow-type plug to be connected instability with elbow-type socket 3, the utility model is also provided with rubber ring 11 at elbow-type socket 3 outer surface, utilizes the elasticity of rubber ring 11 to improve the stable connection of elbow-type plug and elbow-type socket 3 further.
