On side, the iron core is movably placed in what the closing coil, magnetic guiding loop and opening coil and quiet cover board and dynamic cover board were formed
In the buried via hole of center；The quiet cover board, iron core and adjusting nut center are respectively corresponded equipped with through-hole, are fixed in the middle part of the pull rod
In the central through hole of the iron core, activity passes through the through-hole on the quiet cover board and adjusting nut respectively at the both ends of the pull rod；
The spring pocket is set on the pull rod, is placed between the iron core and adjusting nut；The iron core be equipped with it is several and its
The parallel outage 21 of axis direction.
Wherein, the both ends, that is, combined floodgate end 12 and separating brake end 13 of the corresponding pull rod are respectively equipped with close to switch 14.The drawing
Bar stainless steel, the quiet cover board, iron core, magnetic guiding loop, magnetic conductive cylinder and dynamic cover board material are electrical pure iron.The permanent magnet is neodymium iron
Boron material is 150 DEG C using temperature.The closing coil is fixed with the quiet cover board simultaneously, the opening coil simultaneously with institute
Cover board is stated to fix.The medial surface of the closing coil, magnetic guiding loop and opening coil is coplanar.Several outages are uniformly distributed in together
On one periphery, and the axis of the cylindrical body is identical as the axis of the iron core.
The working method of the permanent-magnet manipulating mechanism used in the oil is identical as existing common permanent-magnet manipulating mechanism, again no longer
It repeats.But in order to be suitable for work in oil, designed using some special structures.
Firstly, common mechanisms are in the case where external force is eliminated, mechanism center position there are the equalization point of a permanent magnetic, when
When control system failure or driving energy deficiency, easily make matched vacuum switch there is third state in addition to splitting or integrating lock.This
Utility model has a counterbore in iron core one end center, inside has a spring, withstands on adjusting nut in the other end of spring, pass through
The depth that screws of adjustment adjusting nut and static side lid, adjustable and eliminating machine permanent magnetic equalization point, so that institute is matched
Vacuum switch is not in the third state in addition to splitting or integrating lock, it is ensured that switch can be safely operated.
Secondly, outage is increased in iron core end face under the premise of not influencing iron core magnetic conduction ability, when iron core does conjunction partite transport
When dynamic, the oil liquid of one end can slave outage rapidly flow to the other end so that oil damping power when mechanism action is eliminated,
And there is lubrication and rinse to be attracted end face.
Furthermore common mechanisms stroke detection is using solid metal contact, in oil after a period of work, due to electric arc
Decomposition deterioration to transformer oil, the colloid of generation can pollute contact surface, cause poor contact of contacts or failure.This is practical new
Type use oil-resistant high-temperature close to switch as on/off switch stroke detection device, detected than entity contact it is more stable and reliable,
Longer life expectancy.
It uses and designs it can be seen that the utility model aims in transformer oil, avoid common bi-stable permanent magnetism operating
The deficiency and disadvantage of mechanism；Using the iron core of special designing, so that oil damping power when mechanism action is eliminated；It uses
Close to switch as on/off switch stroke detection, more reliable, longer life expectancy is detected than entity contact；Adjustment spring is had in iron core,
Can with the equalization point of eliminating machine permanent magnetic so that matched vacuum switch be not in third state in addition to splitting or integrating lock,
Ensuring to switch can be safely operated.
