Description
Technical field
The invention belongs to rotary transformer technology field, and in particular to a kind of pressure-resistant insulation bone of magnetoresistance transformer
Frame.
Background technology
Iron core stator in magnetoresistance transformer is formed by stacking by multilayer silicon steel sheet, and coil rack is by two
Piece skeleton is constituted, and the teeth portion of iron core is simultaneously folded in centre by two panels skeleton.Because silicon steel sheet has thickness deviation, therefore superposition system
Into iron core often have larger deviation, iron core tolerance be ± 0.2.Existing two panels skeleton constitute for folding up iron core teeth
The U-type groove in portion is often end contact.If iron core is thicker than design load, thicker iron core can strut the U-type groove at two ends, make two
Gap is left between the end face of U-type groove, so as to spill iron core teeth portion, poor insulativity.If iron core is thinner than design load, the U of two
Type groove bottom land also has gap with two of iron core, assembles of poor quality, easily produces and rocks, also, two end face pressures of U-type groove
Structural stress is big rearward, is easily damaged coil, and resistance to pressure is poor.
The content of the invention
The purpose of the present invention is the defect for overcoming prior art to exist, there is provided a kind of to avoid blocked up iron core from strutting the
First, two U-type groove, is not in gap, will not spill iron core teeth portion, good insulating；The bottom land of the first U-type groove and the second U-type groove
Can fully be fitted with two of iron core, fit-up gap is small；Coil skeleton structure stress after combination is small, is hardly damaged coil, resistance to
The pressure-resistant insulation framework of the good magnetoresistance transformer of pressure property.
The technical solution adopted for the present invention to solve the technical problems is：A kind of pressure-resistant insulation of magnetoresistance transformer
Skeleton, it includes sending down the fishbone circle and upper bone circle, circumferentially disposed on the inner ring of sending down the fishbone circle to have multiple first around head, and each is first on head
Through there is the first U-type groove, the U-shaped opening both sides of each the first U-type groove are equipped with the first chamfering being oppositely arranged；Upper bone circle
On inner ring it is circumferentially disposed have it is multiple with first around head one-to-one second around head, each second on head through there is the 2nd U
Type groove, the U-shaped opening both sides of each the second U-type groove are equipped with the second chamfering set towards outside groove；First U-type groove and second U-shaped
Groove is made up of the stator core teeth portion for wearing magnetoresistance transformer the mutual cooperation of the first chamfering and the second chamfering
Groove.
The structure that first U-type groove of the invention and the second U-type groove are coordinated by chamfering, leaves the surplus compared with multi-expansion, can
Avoid blocked up iron core from strutting the first U-type groove and the second U-type groove, therefore be all the time not in gap, will not more spill iron core teeth
Portion, good insulating.Even if excessively thin iron core assembly, also can by the pressing of the first chamfering and the second chamfering, make the first U-type groove and
The bottom land of the second U-type groove is fully fitted with two of iron core, and fit-up gap is small, and assembling quality is high, firm grip；By a U
The second chamfering in the first chamfering and the second U-type groove in type groove coordinates, and skeleton stress is minimum, the coil skeleton structure after combination
Stress is small, is hardly damaged coil, and resistance to pressure is good.
Specifically, two first of arbitrary neighborhood are connected around head by the first connecting plate, are used to connect on the first connecting plate
The 3rd chamfering outside sending down the fishbone circle circle is provided with the edge of upper bone circle；Two second of arbitrary neighborhood are around head by the second connection
Plate is connected, and is used to connect the 4th chamfering being provided with the edge of sending down the fishbone circle in bone circle circle on the second connecting plate, and the 3rd falls
Angle and 4th chamfering cooperate.The mutual cooperation of the 3rd chamfering of the invention and 4th chamfering further enhancing above-mentioned insulation
Property, assembling quality and resistance to pressure.
Preferably, the first chamfering, the second chamfering, the 3rd chamfering and 4th chamfering are 60 ° of chamferings, and length of grade is larger, has
Larger surplus is stretched, it is to avoid the insulating properties influence that blocked up iron core brings.
Further, upper bone circle side is fixed with junction board, facilitates wiring.
Further, the table top of junction board is provided with and melts glue groove, and melting glue groove can be with solidifying hot-melt adhesive, and convenient fixation is melted
Each enamel-covered wire for separating in glue groove, it is to avoid each enamel-cover linear contact lay, further increases the quality of production.
Further, multiple is evenly distributed on the outlet end face of upper bone circle and crosses terminal, and each terminal of crossing is along upper bone circle
Inner ring edge is arranged；The height for crossing terminal exceeds the height of outlet end face more than the enamel-cover line winding in upper bone circle.The structure can
Effectively protect wire body, it is to avoid collide with enamel-covered wire；And in storage, due to crossing the support of terminal, it is difficult to damage winding by pressure during stacking,
And the impurity foreign matter in Exciting Windings for Transverse Differential Protection on not easy-adhesion lodging bench face.Additionally, the terminal excessively being circular layout of the invention, coordinates certainly
After dynamic coil winding machine, can further facilitate and realize Full-automatic coiling technique.
A kind of beneficial effect of the pressure-resistant insulation framework of magnetoresistance transformer of the invention is：
1. the structure that the first U-type groove of the invention and the second U-type groove are coordinated by chamfering, leaves the surplus compared with multi-expansion,
Blocked up iron core can be avoided to strut the first U-type groove and the second U-type groove, therefore be all the time not in gap, will not more spill iron core
Teeth portion, good insulating；
Even if 2. excessively thin iron core assembly, also can make the first U-type groove and by the pressing of the first chamfering and the second chamfering
The bottom land of two U-type grooves is fully fitted with two of iron core, and fit-up gap is small, and assembling quality is high, firm grip；By the first chamfering
With the cooperation of the second chamfering, skeleton stress is minimum, and the coil skeleton structure stress after combination is small, is hardly damaged coil, resistance to pressure
It is good.
