The utility model is to solve technical solution used by its technical problem: a kind of transformer oil immersed type vacuum
Contactor, including the mounting plate being fixed on transformer shell outside, the Insulating frame, the vacuum switch that are placed in transformer oil
Pipe and insulated pull rod, and it is placed in the housing on the outside of transformer shell and the permanent-magnet manipulating mechanism in the housing；It is described exhausted
Edge frame is installed on the one side of the mounting plate, and the housing and permanent-magnet manipulating mechanism are installed on the another of the mounting plate
On side；The vacuum switch tube is fixed in the Insulating frame, and passes through the insulated pull rod and the permanent magnetic operating machine
Structure connection.
The permanent-magnet manipulating mechanism is dedicated permanent-magnet manipulating mechanism in oil as a further improvement of the utility model,
At work, transformer oil is full of in the housing.
Rubber oil seal knot is equipped between the insulated pull rod and mounting plate as a further improvement of the utility model,
Structure.
The control box of the oil immersed type vacuum contactor is installed on transformer shell as a further improvement of the utility model,
On outside, it is connected by the cable with shielded layer with the ontology of the oil immersed type vacuum contactor.
The beneficial effects of the utility model are: transformer oil immersed type vacuum contactor, firstly, utilizing transformer oil
Superelevation insulating properties replaces the air insulation of traditional contactors, and overall volume narrows down to the 1/5 of traditional contactors hereinafter, greatly dropping
The cost of low contactor also reduces the cost of corollary equipment simultaneously；Secondly, utilizing the high-air-tightness of transformer oil, lubrication
Property, so that the leakage rate of contactor vacuum switch tube greatly reduces, storage time is greatly prolonged, and very little is worn, in lifetime
It is interior can be non-maintaining；Furthermore it is external using permanent-magnet manipulating mechanism, the application mode of layout is separated with major loop, simplifies transformation
The annual overhaul of device and contactor is safeguarded, it is lower to be more convenient cost；And contactor control box is separated with ontology, is more convenient to become
The design layout of depressor, it is safer, it can power-on serving.In short, the oil immersed type vacuum contactor is using oil liquid as storage condition
And lubricant, have many advantages, such as that contactor leak rate substantially reduces, overall wear is minimum, the service life is long, non-maintaining.

Specific embodiment
Below in conjunction with attached drawing, elaborate to a preferred embodiment of the utility model.But the guarantor of the utility model
Shield range is not limited to following embodiments, i.e., in every case with simple made by present utility model application the scope of the patents and description
Equivalent changes and modifications all still belong within the utility model patent covering scope.
Refering to fig. 1-3, it is a kind of transformer oil immersed type vacuum contactor described in the utility model, including is fixed on change
Mounting plate 1 on 100 lateral surface of depressor shell, the Insulating frame 2 being placed in transformer oil 101, vacuum switch tube 3 and insulation are drawn
Bar 4, and the housing 5 for being placed in 100 outside of transformer shell and the permanent-magnet manipulating mechanism 6 in the housing；The insulation frame
Frame 2 is installed on the one side of the mounting plate 1, and the housing 5 and permanent-magnet manipulating mechanism 6 are installed on the another of the mounting plate 1
On one side；The vacuum switch tube 3 is fixed in the Insulating frame 2, and is grasped by the insulated pull rod 4 with the permanent magnetism
Motivation structure 6 connects.
The oil immersed type vacuum contactor during installation, does sealing by mounting plate 1 and 100 lateral surface of transformer shell and connects
It connects, keeps good oil seal.The contactor major loop that Insulating frame 2, vacuum switch tube 3 and insulated pull rod 4 are constituted, which is located at, to be become
In depressor oil 101, transformer oil liquid level is immersed in hereinafter, so as to replace tradition to connect using the superelevation insulating properties of transformer oil
The air insulation of tentaculum, overall volume narrow down to 1/5 or less traditional contactors.The permanent-magnet manipulating mechanism of contactor passes through housing
Be fixed on the outside of transformer shell, that is, be placed outside outside transformer oil, form the mode for separating layout with major loop, easy access with
Maintenance.
Wherein, the permanent-magnet manipulating mechanism is that dedicated permanent-magnet manipulating mechanism is full of in the housing at work in oil
Transformer oil, for lubricating and balancing pressure, when on/off switch being avoided to move, oil liquid is by compression bring damping force.
Rubber oil seal structure is equipped between the insulated pull rod and mounting plate, to the insulated pull rod and mounting plane of transmission
Oil seal is done, so that permanent-magnet manipulating mechanism and the oil liquid of inside transformer are not leaked and polluted mutually.
The control box 7 of the oil immersed type vacuum contactor is installed on 100 lateral surface of transformer shell, passes through band shielded layer
Cable be connected with the ontology of the oil immersed type vacuum contactor, avoid transformer itself high-intensity magnetic field and strong electrical field radiation zone come
Electromagnetic interference.
It can be seen that transformer oil immersed type vacuum contactor, firstly, the superelevation insulating properties using transformer oil replaces
The air insulation of traditional contactors, overall volume narrow down to the 1/5 of traditional contactors hereinafter, greatly reducing making for contactor
Valence also reduces the cost of corollary equipment simultaneously；Secondly, using the high-air-tightness of transformer oil, lubricity, so that contactor is true
The leakage rate of empty switching tube greatly reduces, and storage time greatly prolongs, and wears very little, can be non-maintaining in lifetime；Again
Person, it is external using permanent-magnet manipulating mechanism, the application mode of layout is separated with major loop, simplifies the year of transformer and contactor
It is lower to be more convenient cost for repair and maintenance；And contactor control box is separated with ontology, is more convenient the design layout of transformer, more
Safety, can power-on serving.In short, the oil immersed type vacuum contactor uses oil liquid as storage condition and lubricant, there is contact
The advantages that device leak rate substantially reduces, overall wear is minimum, the service life is long, non-maintaining.
