Description

A kind of transformer isolation is switched with rotary dynamic/static contact structure
Technical field
The present invention relates to field transformer, specifically a kind of transformer isolation is switched with rotary dynamic/static contact structure.
Background technology
Transformer is the device for changing alternating voltage using the principle of electromagnetic induction, and main member is armature winding, secondary Level winding and iron core, wherein armature winding, the line end of secondary windings need to connect binding post, be connected by binding post and other equipment Connect.The break-make of circuit between transformer and load is realized in transformer using disconnecting switch, and disconnecting switch its structure is typically constituted from Z-direction space is larger, because the rotating bar in disconnecting switch where moving contact needs to take Z-direction space, causes transformation Device can not be minimized, and when dynamic and static contact is mutually disengaged in prior art disconnecting switch, moving contact is still by moving contact Binding post is connected with load, when there is electric arc or moving contact remains electric current, and load can be damaged.
The content of the invention is switched with rotary dynamic/static contact structure it is an object of the invention to provide a kind of transformer isolation, with Solve moving contact in prior art disconnecting switch and take the problem of Z-direction space is larger.
In order to achieve the above object, the technical solution adopted in the present invention is:
A kind of transformer isolation is switched with rotary dynamic/static contact structure, it is characterised in that:Including rotatable insulating materials branch The moving contact of arc is provided with the top of the rotating disk of support, rotating disk close to upper right side marginal position, rotating disk top left side is fixedly arranged above absolutely Edge seat, insulating base upper right side be provided with V-arrangement static contact, static contact V-arrangement one end stretch to moving contact arc left end and with moving contact arc Shape left end makes electrical contact with, and the static contact V-arrangement other end is connected with static contact binding post, and the extrados of the moving contact is connected with electricity Brush, also includes the electric conductor being fixedly installed near moving contact brush, and the electric conductor makes electrical contact with brush, and electric conductor connects It is connected to moving contact binding post.
A kind of described transformer isolation is switched with rotary dynamic/static contact structure, it is characterised in that:The electric conductor with The face that brush contacts with each other is set to cambered surface.
A kind of described transformer isolation is switched with rotary dynamic/static contact structure, it is characterised in that:The rotating disk middle position To extension line venthole is provided with the arc of moving contact arc left end, rotating disk bottom correspondence outlet hole site is provided with air chamber, air chamber Interior upper end is connected with venthole.
A kind of described transformer isolation is switched with rotary dynamic/static contact structure, it is characterised in that:The moving contact with The face that static contact contacts with each other is set to inclined-plane.
By rotating rotating disk in the present invention, moving contact can be made by itself arc left end and static contact V-arrangement end thereof contacts, or Depart from static contact V-arrangement one end, overall structure need not take larger Z-direction space, be conducive to the Miniaturization Design of transformer.
In the present invention, moving contact is connected by brush with electric conductor in itself, then passes through electric conductor and moving contact binding post Connection, when moving contact and static contact disengaging, brush equally departs from electric conductor, realizes that moving contact disconnects also relative to load, Load will not also be damaged even if there is electric arc and residual current.
In the present invention, rotating disk is provided with venthole and air chamber, when rotating disk, which turns to moving contact, to be departed from static contact, venthole Position turn between dynamic and static contact, now air chamber by venthole to jet-stream wind between dynamic and static contact, can be effectively real Existing arc-suppression function.
The present invention can make disconnecting switch to take excessive Z-direction space, be conducive to the Miniaturization Design of transformer, and Realize and depart between moving contact and load when dynamic and static contact departs from, improve the security used.

Embodiment
As shown in Figure 1 and Figure 2, a kind of transformer isolation switch rotary dynamic/static contact structure, including rotatable insulation The rotating disk 1 of materials for support, the top of rotating disk 1 is provided with close to upper right side marginal position in the moving contact 2 of arc, the top left side of rotating disk 1 Side is fixed with insulating base 3, and the upper right side of insulating base 3 is provided with the static contact 4 of V-arrangement, and it is left that the arc of moving contact 2 is stretched in static contact 4V shapes one end Hold and made electrical contact with the arc left end of moving contact 2, the static contact 4V shape other ends are connected with outside static contact binding post 5, moving contact 2 Cambered surface is connected with brush 6, also includes the electric conductor 7 being fixedly installed near the brush 6 of moving contact 2, electric conductor 7 and the electricity of brush 6 Contact, and electric conductor 7 is connected with moving contact binding post 8.
Electric conductor 7 is set to cambered surface with the face that brush 6 contacts with each other.
The arc for being located at the arc left end of moving contact 2 in rotating disk 1 is provided with venthole 9, the bottom of rotating disk 1 correspondence outlet to extension line The position of hole 9 is provided with upper end in air chamber 10, air chamber 10 and is connected with venthole 9.
Moving contact 2 is set to inclined-plane with the face that static contact 4 contacts with each other.
