Embodiment

For making the object of the utility model embodiment, technical scheme and advantage clearly, doing below with reference to the embodiment of Fig. 1 to Fig. 4 to the utility model transformer framework and describing clearly and completely further.Obviously, described embodiment is section Example of the present utility model, instead of whole embodiments.Based on described embodiment of the present utility model, the every other embodiment that those of ordinary skill in the art obtain under without the need to the prerequisite of creative work, all belongs to the scope of the utility model protection.

A kind of transformer framework, comprise a system skeleton 1, a described system skeleton 1 comprises around post 2, be arranged at the baffle plate 3 around the relative end of 2 two, post, be arranged at around post 2 outer ring and insulation division 4 between two baffle plates 3, the material that a system skeleton 1 in the present embodiment adopts is bakelite, compare common ambroin bakelite to have and do not absorb water, high-insulativity, high temperature resistant, intensity high, in this example around the shape of post 2 be cuboid, insulation division 4 and two plate washers about being positioned at it form the cell body of coiling primary coil and secondary coil respectively, two coilings separate by insulation division 4, described extension 5 comprises at least two extensions 51, and be set in distance between adjacent elongated members 51, extension 51 may be used for fixing the end of a thread, lead-in wire the end of a thread can be prevented the entanglement that goes between when coiling by employee on extension 51, on the other hand when employee winds coil, coil the end of a thread and lead-in wire all can be fixed on extension 51, one can prevent the end of a thread entanglement, two can allow coil deposit and movement process in keep the state of taking up to ensure mass of coil, lead-in wire the end of a thread due to coil has a lot, the end of a thread all may seem more too fat to move on an extension 51, multiple extension 51 is adopted while fixing the end of a thread, to make the end of a thread divide clearly, gap is left between adjacent elongated members 51, when bobbin winding head, employee can carry out keeping away position, employee wherein extension 51 bobbin winding head time can avoid meeting another extension 51, coiling is more convenient.

The preferred structure adopting two extensions 51 in the present embodiment, described two extensions 51 stretch out opening-like, i.e. open-ended increasing away from baffle plate 3 of two extensions 51, between gap increasing, two extensions 51 to meet while the end of a thread is wound around demand and ringently can arrange lower convenient employee's coiling at it, and opening shape makes the effective clearance between two extensions 51 larger.

Described extension 5 is provided with time extension 6 away from the end of skeleton, the length direction of secondary extension 6 is arranged with the length direction of extension 5 is vertical each other, it is the same that secondary extension 6 is just equivalent to spacing block, makes to skid off from the end of extension 5 around the end of a thread on extension 5.

Described extension 5 is provided with reinforcement 7, because extension 5 needs bobbin winding head, certain power can be used to make the tighter of wire-wound when coiling, now extension 5 just may rupture, and arranges reinforcement 7 and can improve its mechanical strength.

The intersection 14 of described extension 6 and extension 5 is provided with fillet 8, because wire is all thinner, adopts fillet 8 that wire can be avoided to be cut off in the position that extension 5 and time extension 6 connect.

Described baffle plate 3 is also provided with for temperature sensor mounted installing hole 9 away from the side around post 2, transformer its temperature when working or transship can constantly raise, present transformer understands mounting temperature sensor mostly to monitor the temperature of transformer, when the temperature of transformer reaches limit value, temperature sensing will be reported to the police or automatic shutdown circuit, installing hole 9 is being set away from the side around post 2, is facilitating the later stage to the detection of transducer or replacing.

The flange of described installing hole 9 is provided with the bayonet socket 10 for limit sensor position, and in the present embodiment, bayonet socket 10 is three and circumference is distributed on the flange of installing hole 9, and temperature sensor is placed on and installing hole 9 fixedly limits it by bayonet socket 10 moves.

Describedly be provided with along running through the groove 11 of two plate washers around post 2 axial direction around post 2, described baffle plate 3 is also provided with two limiting plates 12 away from the side around post 2, described limiting plate 12 is provided with strip fin 13 near the side of groove 11, groove 11 is for settling magnetic core, magnetic core used in the present embodiment is M shape structure, the middle part of M shape magnetic core is inserted in groove 11, limiting plate 12 swings for limiting magnetic core and has certain fastening effect, strip fin 13 on limiting plate 12 can increase the pressure of limiting plate 12 pairs of magnetic cores, plays better fastening effect.

The above is only exemplary embodiment of the present utility model, but not for limiting protection range of the present utility model, protection range of the present utility model is determined by appended claim.
