Abstract
The invention discloses a matching structure for ensuring the reliable contact of the head portion of a sleeve and carrying current.The matching structure comprises a spring structure, a conductive head and a lead connector.The spring structure can be movably put between the conductive head and the lead connector and limited by a lead connector limiting groove, the spring structure can also be connected with the conductive head, the lead connector and the conductive head are connected with the carrying current through threads, the spring structure is compressed when the lead connector is screwed in the conductive head, and the lead connector and the conductive head are matched through the threads and closely meshed under the acting force of the spring structure.The lead connector and the conductive head are closely meshed at the matching positions of the threads, the reliable carrying current at the matching positions of the threads is ensured, and the phenomenon that since the matching thread of the head portion of the sleeve is poor in contact, the head portion of the sleeve is too hot can be effectively solved.
Description
Technical field
The present invention relates to transformer accessory field, be specifically related to a kind of fit structure ensureing bushing head reliable contacts current-carrying.
Background technology
Bushing shell for transformer 1250A and following current class commonly use wears cable formula structure, wearing cable formula structure facilitates sleeve pipe to install at the scene, transformator is also without opening installation hand hole, transformator line cable welding or be crimped on pigtail splice, owing to bushing head needs to seal with conductive head (being commonly called as army cap), because conductive head and pigtail splice are generally used threaded engagement to carry out current-carrying by the industry.
Threaded engagement is required higher by screw thread current-carrying, although each producer also takes some measures and improves screw thread current-carrying condition herein, but not having a kind of structure so far is fully effective this problem of solution.When the bad meeting of threaded engagement causes running, screw thread electric shock resistive indirectly is big, and temperature is too high, and the too high meeting of temperature causes that in sleeve pipe, transformer oil and insulation ag(e)ing are accelerated, and reentrant bushing service life, impact runs safety.
Summary of the invention
For the problems referred to above, the present invention provides a kind of fit structure ensureing bushing head reliable contacts current-carrying.
The purpose of the present invention realizes by the following technical solutions:
A kind of fit structure ensureing bushing head reliable contacts current-carrying, it is characterized in that, including conductive head, spring structure and pigtail splice, described pigtail splice and conductive head are threaded connection and current-carrying, spring structure is arranged between conductive head and pigtail splice, pigtail splice screws in compression spring structure during conductive head inside, and pigtail splice and conductive head are closely engaged by the active force of spring structure at screw thread place.
Preferably, described spring structure is single spring, and the top of pigtail splice is provided with stopper slot, and spring structure activity is positioned between conductive head and pigtail splice, and spacing by stopper slot.
Preferably, described spring structure includes spring, stator, and spring is positioned at the lower section of stator and one-body molded with stator, and spring structure is fixed on the inner surface of conductive head entirely through securing member；Stator and conductive head are additionally provided with the fixing hole used with described appended claims.
Preferably, between described securing member and fixing hole it is threaded engagement.
The invention have the benefit that the setting by spring structure, pigtail splice and conductive head matching thread are closely engaged, ensure that threaded engagement place current-carrying is reliable, can effectively solving the phenomenon that in present industry, the loose contact of bushing head matching thread causes bushing head overheated, structural reliability is high, easily realize.

Accompanying drawing labelling: conductive head-1；Spring structure-2；Pigtail splice-3；Securing member-4；Screw thread-5；Stopper slot-6；Fixing hole-7；Stator-21；Spring-22.
Detailed description of the invention
The invention will be further described with the following Examples.
Embodiment 1:
A kind of fit structure ensureing bushing head reliable contacts current-carrying as shown in Figure 1, including conductive head 1, spring structure 2 and pigtail splice 3, pigtail splice 3 and conductive head 1 are connected and current-carrying by screw thread 5, spring structure 2 is single spring, the top of pigtail splice 3 is provided with stopper slot 6, spring structure 2 activity is positioned between conductive head 1 and pigtail splice 3, and spacing by stopper slot 6.Pigtail splice 3 screws in compression spring structure 2 during conductive head 1 inside, and pigtail splice 3 and conductive head 1 are closely engaged by the active force of spring structure 2 at screw thread 5 place.
In the fit structure of this embodiment, spring structure 2 two ends are conflict contact, and only spacing by stopper slot 6, advantage is simple in construction, it is not necessary to other adnexaes；Spring 5 must first put into when being disadvantageous in that installation stopper slot 6, and operation needs relatively careful, is otherwise easily caused the skew of spring 5 position and causes unbalance stress, and when dismantling, spring 5 easily drops and loses on the ground.
Embodiment 2:
A kind of fit structure ensureing bushing head reliable contacts current-carrying as shown in Figure 2, including conductive head 1, spring structure 2 and pigtail splice 3, pigtail splice 3 and conductive head 1 are connected and current-carrying by screw thread 5, spring structure 2 is arranged between conductive head 1 and pigtail splice 3, it includes spring 22, stator 21, spring 22 is positioned at the lower section of stator 21 and one-body molded with stator 21, and spring structure 2 is fixed on the inner surface of conductive head 1 entirely through securing member 4.Stator 21 and conductive head 1 are additionally provided with securing member 4 with the use of fixing hole 7, it is preferable that be threaded engagement between securing member 4 and fixing hole 7.Pigtail splice 3 screws in compression spring structure 2 during conductive head 1 inside, and pigtail splice 3 and conductive head 1 are closely engaged by the active force of spring structure 2 at screw thread 5 place.
In the fit structure of this embodiment, although structure relatively embodiment 1 is slightly complicated, but owing to spring structure 2 is fixed on conductive head 1, during installation and removal all more convenient, and Stability Analysis of Structures can guarantee that conductive head 1 and pigtail splice 3 are in screw thread 5 cooperation place uniform force, do not produce the situation of hot-spot.
The present invention setting by spring structure 2, pigtail splice 3 and conductive head 1 matching thread are closely engaged, ensureing that threaded engagement place current-carrying is reliable, it is possible to effectively solve the phenomenon that in present industry, bushing head matching thread loose contact causes bushing head overheated, structural reliability is high, easily realize.
Finally should be noted that; above example is only in order to illustrate technical scheme; but not limiting the scope of the invention; although having made to explain to the present invention with reference to preferred embodiment; it will be understood by those within the art that; technical scheme can be modified or equivalent replacement, without deviating from the spirit and scope of technical solution of the present invention.
