Description

A kind of electric connection structure of GIS combined electrical apparatus
Technical field
The utility model relates to a kind of electrical equipment technical field, specifically a kind of electric connection structure of GIS combined electrical apparatus.
Background technology
The SF6 fully closed combined electric unit is called for short GIS again, mainly is made up of circuit breaker, isolating switch, earthed switch, current transformer, voltage transformer, lightning arrester, sleeve pipe, bus, and these parts are called the functional unit of GIS again.Wherein, the effect of bus unit is exactly to compile, distribute and transmit electric energy and be connected other functional units.So bus unit reliability of operation is all most important to the whole piece transmission line.In practicality, for making things convenient for the butt joint of each functional unit of product, the bus unit is all made the length and the structure of standard usually, carries out assembly unit according to the requirement of actual engineering then.The bus unit mainly comprises bus bar canister, disc insulator, conducting rod and electrical connection.The contact form of Mume flower contact is adopted in more common electrical connection at present more.This structure has following several shortcoming:
1, complex structure.Only conducting rod just is made up of three parts: contact tube and joint are by being threaded, and joint and plug screw are strained with bolt.Mume flower contact is made up of five parts: fingertip seat, conductive seat, plum blossom fingertip, guide post, radome.Part is many more, represents conducting surface many more, and contact resistance is big more, causes loose contact because of heating also easily more.
2, efficiency of assembling is low.Because the contact area of monolithic plum blossom fingertip and conducting rod joint is less, for guaranteeing that enough cocurrent flow abilities just must guarantee the sheet number of enough plum blossom fingertips, for example, the 4000A rated current needs about 40 plum blossom fingertip, the 5000A rated current needs 50, all need manual finishing, as seen, singly is the plum blossom fingertip to be installed just need expend a large amount of installation times.
3, manufacturing cost height.Because parts are more, and be to guarantee each parts favorable conductive rate, it is silver-plated that each parts mostly is fine copper, is unfavorable for cost control.
Summary of the invention
In order to solve the problems of the technologies described above, it is a kind of simple and reasonable for structure that the utility model provides, and conducts electricity very well, electronic and thermal stability is high, easily the electric connection structure of the GIS combined electrical apparatus of I﹠M.
The technical solution adopted in the utility model is: a kind of electric connection structure of GIS combined electrical apparatus, comprise contact tube, contact base and radome, also comprise guide ring and power spring, described contact base in a tubular form, be arranged in the radome, the one end is connected with conductive seat, the other end is connected with guide ring, described guide ring is a conical ring, guide ring is placed in the outside, end of contact base, on the outer wall of contact base, one side of guide ring is provided with the annular groove that power spring is installed, and power spring is arranged in this groove, and described contact tube stretches in the radome and tightly is placed in guide ring, the outside of power spring and contact base.
Described guide ring and contact base are clamping, and this guide ring is that nylon or plastics are made.
Described contact base is that the cast aluminium alloy casting is made.
The utility model is at contact base arranged outside power spring, and contact tube is simplified electric connection structure by power spring and contact base conduction, increases contact area, and electric conductivity is good, and is electronic and thermal stability is high; In the contact base end taper guide ring is set, contact tube needn't be specially to the heart when being connected with contact base like this, and the guide ring of taper can make the contact tube self-centering, prevent loose contact, easy I﹠M, and, the end contact base wearing and tearing of guide ring protection contact base are arranged; When existing short-circuit electromotive force to do the time spent, fixing contact tube position and make contact tube and touch base electric insulation, the ablation or the weldering that avoid that both collide, shunting, loose contact cause are dead.
Description of drawings
Fig. 1 is a structural representation of the present utility model
Embodiment
Now in conjunction with the accompanying drawings the utility model is further described, Fig. 1 is a kind of embodiment of the present utility model, and this mechanism mainly comprises several parts such as contact tube 1, contact base 2, radome 3, guide ring 4 and power spring 5.Described contact base 2 places in the radome 3 in a tubular form, and the one end is connected with conductive seat, and the other end is connected with guide ring 4.Guide ring 4 is a conical ring, be installed in the end outside of contact base 2, its rear portion is provided with trip and contact base 2 clampings, and guide ring 4 of the present utility model can be made for nylon or plastics, this material is softer, can not cause any infringement to the conducting surface of contact tube 1.On the outer wall of contact base 2, one side of guide ring 4 is provided with the annular groove that power spring 5 is installed, power spring 5 is arranged in this groove, described contact tube 1 stretches in the radome 3 and tightly is placed in the outsides of guide ring 4, power spring 5 and contact base 2.Contact base 2 in the present embodiment is made for the cast aluminium alloy casting.
The utility model conducts electricity by contact tube 1 inner surface compression conductive spring 5, compare with traditional structure, omitted the structure of joint, plug screw, touch base also adopts integrative-structure, reduced the conducting surface of fingertip seat and contact base 2 assemblings in the traditional structure, simple in structure; The utility model only needs power spring 5 is enclosed within on the contact base 2, again guide ring 4 is connected on the contact base 2 and can finishes, and does not need any instrument auxiliary, improves efficiency of assembling; In addition and since guide ring 4 from the aligning effect, also the two ends of school amount contact tube 1 are concentric repeatedly during assembling, contact tube 1 hand steered insertion gets final product, also can realize the one man operation under frock cooperates, omit miscellaneous plum blossom fingertip assembly work again, operating efficiency can be significantly improved.
This shows, the utlity model has simple in structurely that conduct electricity very well, the dynamic thermal stability height is easy to the characteristics such as I﹠M.
