The high-tension line of electricity carries out electrical isolation；Switch busbar；Automatically quickly isolate, to ensure the safety of service personnel.
At present, there are following urgent problems to be solved for active service disconnecting switch：Isolation switch contact spring leaf or spring are long-term
It is placed in rugged environment, corrosion phenomena occurs, after corrosion, spring leaf or spring force decline, and cause fingertip and contact
Resistance increases；Disconnecting switch fingertip material and size and the requirement of silver coating technology are unsatisfactory for relevant criterion requirement, in actual fortune
Through-current capability deficiency, easily generates fever phenomenon in row；The silver coating hardness of fingertip is inadequate, in moving process excessive thinning or
It comes off, in disconnecting switch operation, contact is easily subject to ambient enviroment (such as chemical emission, salt-alkali contaminated, rain erosion, oxidation
Corrosion) influence so that the gradual corrosion in conductive portions contact face, formed oxide layer, contact resistance is caused to become larger, causes fever；
Fingertip and spring leaf and the bolt of button contact base bearing are also easy to produce loosening during the impact vibration of multiple divide-shut brake, cause this
, there is disconnecting switch problem in the increase fever of location contacts resistance.
And isolation switch contact is the key position of disconnecting switch conduction, if electric energy can be not only lost in contact fever, sternly
The meeting of weight causes contact burning, so as to cause the generation of large area blackout, generates heavy economic losses and severe social shadow
It rings.To avoid this phenomenon appearance, power department input energy attempts to solve, and a large amount of frequently maintenance can also expend largely
Man power and material to the disconnecting switch, it is necessary to make improvement.
A kind of high voltage isolator of patent, application number (CN201610703555.1), including pedestal and operating-controlling mechanism, pedestal

Moving contact is connected, and operating-controlling mechanism is located at the lower section of pedestal, is provided with tracheae and control handle above operating-controlling mechanism, tracheae with
Second support insulator is connected.The high voltage isolator solves the problems, such as rain cover waterproof, fire-retardant, but needed for the disconnecting switch
Component proportioning it is complicated, sustainable usability is poor, of high cost, and can not solve with usage time increase caused by contact oxygen
Change and whole heating problem.
Therefore be badly in need of will it is a kind of it is simple in structure, material easily selects, state can adjust automatically, it is affected by environment it is small, do not generate heat
Intelligent isolation switch.
The content of the invention
It is complicated, sustainable to solve prior art material proportioning the object of the present invention is to provide a kind of Intelligent isolation switch
The problem of usability is poor, of high cost, affected by environment big.
In order to achieve the above objectives, the present invention is achieved by the following scheme：
A kind of Intelligent isolation switch, the bottom plate including pedestal and on pedestal are arranged with two insulation on bottom plate
Son；A connecting rod, connecting rod flexible connection insulator are connected in the middle part of bottom plate；Insulator is fixedly arranged above conductive mechanism, conductive
Mechanism includes the junction block and contact that are electrically connected with each other；Contact include fingertip and be symmetrically set in fingertip both ends button contact base,
Spring leaf and memorial alloy fastener, spring leaf and button contact base connect fingertip by memorial alloy fastener.
Further improve of the invention is：
L-shaped terminal plate is equipped at the top of junction block, L-shaped terminal plate is equipped with several mounting holes, and two one group of mounting hole is in
"eight" shape is arranged.
Contact is equipped with conductive arm, and conductive arm connects junction block by a bolt assembly.
A phenolic resin plate is additionally provided between spring leaf and fingertip, size and the button contact base of phenolic resin plate match.
Spring leaf uses external pressure spring leaf.
External pressure spring leaf uses Ultimum Ti alloy.
Fingertip uses chrome zirconium copper alloy.
Fingertip surface is coated with hard silver layer.
Memorial alloy fastener is memorial alloy gasket.
Compared with prior art, the invention has the advantages that：
First, the present invention makes the sustainable offer bullet of spring leaf using external pressure spring leaf, and using Ultimum Ti
Power oppresses both sides fingertip, makes the pressure kept constant between fingertip and contact, enhances operation stability；Using chrome zirconium copper alloy
Fingertip, and electroplate, it is long with good electric conductivity and intensity, thermal stability, whole service life；Secondly, the present invention adopts
With memorial alloy fastener, when being loosened in contact position, restoring force can be automatically generated, increases contact position pressure, attenuating connects
It gets an electric shock and hinders, the automatic contact position that solves is because loosening the heating problem generated, raising disconnecting switch overall operation security；Finally, originally
Invention is easy to operate convenient for adjusting disconnecting switch using the connecting rod in the middle part of bottom plate；Overall structure of the present invention is simple, at low cost, property
It can stablize, is strong to environment resistance, it is easy to spread.
