Specific embodiment

The following will be combined with the drawings in the embodiments of the present invention, carries out the technical scheme in the embodiment of the utility model Clearly and completely describe, it is clear that the described embodiments are only a part of the embodiments of the utility model, rather than whole Embodiment.Based on the embodiments of the present invention, those of ordinary skill in the art are without making creative work Every other embodiment obtained, fall within the protection scope of the utility model.

Fig. 1-5 is please referred to, the utility model provides a kind of technical solution: a kind of unshielded insulation output power supply change of three winding Depressor, including power transformer main body 6, power transformer main body 6 are placed in the inside of transformer outer container 2, and transformer outer container 2 Top is connected with movable doorboard 4, and the back adhesive of transformer outer container 2 is fixed with rubber pad 15, and the height of rubber pad 15 Less than the height of transformer outer container 2, and the material of transformer outer container 2 and movable doorboard 4 is iron, in the mistake using the device Cheng Zhong, the problem of more paying attention to magnetic screen due to transformer, and use iron, then it can pass through transformer outer container 2 and movable doorboard 4 Guarantee the stability that power transformer main body 6 works when power transformer main body 6 works, and is made outside transformer using iron Cost is relatively low for case 2 and movable doorboard 4, and batch is suitble to use；And rubber pad 15 then can make to become when installing transformer outer container 2 2 back side of depressor outer container is more bonded with 1 inner sidewall of power shell, generates to reduce when power transformer main body 6 works Vibration；The lower end of transformer outer container 2 is mounted with fan 9, and 9 two sides of fan are provided with ventilating duct 7, ventilating duct 7 and transformer The inner sidewall of outer container 2 is bonded, and 7 side of ventilating duct offers air outlet 5, and ventilating duct 7 is " Kan " shape structure, and air outlet 5 Side about ventilating duct 7 is in longitudinal equidistantly distributed, and during using the device, the cold wind that fan 9 generates can pass through Ventilating duct 7 is dissipated to the punishment of air outlet 5, is made to can play good heat dissipation to power transformer main body 6 by air outlet 5 With temperature is excessively high and lead to reduced lifetime when power transformer main body 6 being avoided to work；Bottom plate 10 is welded at the top of fan 9, The inside grooves opened up inside bottom plate 10 are connected with the second sliding block 14, and 14 top of the second sliding block is connected with fixed plate 8, Gu Fixed board 8 constitutes bascule by the second sliding block 14 and bottom plate 10, agrees with inside the card slot opened up inside fixed plate 8 and lays electricity Source transformer body 6, bottom plate 10 and fixed plate 8 constitute parallel construction, and the length of bottom plate 10 and fixed plate 8 is equal to ventilating duct The distance between 7 inner sidewalls, then can be with since bottom plate 10 and fixed plate 8 constitute parallel construction during using the device It avoids fixed plate 8 from occurring the phenomenon that inclination is shaken in activity, and then the power transformer main body 6 of 8 top of fixed plate is played The effect of protection；2 side of transformer outer container, which is fixedly connected by welding, the first sliding block 11, the first sliding block 11 and 3 structure of slide bar At slide construction, and 11 one end of the first sliding block is fixedly connected with nut 12, and 12 internal whorl of nut is connected with screw rod 13, and first is sliding Block 11 is right angle "u"-shaped, and the first sliding block 11 is distributed with 2 groups about the longitudinal centre line bilateral symmetry of transformer outer container 2, Every group has 2, during using the device, since the first sliding block 11 is right angle "u"-shaped, then can make the first sliding block 11 are stuck in the surface of slide bar 3, consequently facilitating the installation and removal of transformer outer container 2 and power shell 1, solve staff Transformer outer container 2 and the lower problem of 6 efficiency of power transformer main body are installed；Slide bar 3 is located on power shell 1,3 side of slide bar Groove structure is offered, the width for the groove that 3 side of slide bar opens up is greater than the diameter of screw rod 13, and the unshielded isolation of the three winding is defeated Power transformer can realize fixed plate 8 in the purpose of 2 internal activity of transformer outer container, to pass through by the second sliding block 14 out Power transformer main body 6 is agreed in the groove on 8 surface of fixed plate, power transformer main body 6 is made to be placed in transformer outer container 2 Internal work is more convenient；The device can also make 13 one end of screw rod by the inner rotation screw rod 13 in nut 12 The inside grooves on 3 surface of slide bar are against, so that the first sliding block 11 be made to be fixed on the surface of slide bar 3, are thus being convenient for outside transformer The fixation and disassembly of case 2 and power shell 1, and then improve the working efficiency of the installation and removal of power transformer main body 6.

Working principle: in insulation output power supply transformer unshielded using the three winding, letter is carried out to the present apparatus first Single understanding, understanding later is again to check to the important part portion of the present apparatus, check after there is no problem again it is formal enter make With when installing power transformer main body 6, fixed plate 8 is passed through the in use, install first to power transformer main body 6 Two sliding blocks 14 slide on 10 surface of bottom plate, so that fixed plate 8 is skidded off the inside of transformer outer container 2, then by power transformer main body 6 Basis rest in the groove on 8 surface of fixed plate, after power transformer main body 6 is placed, then sliding by the second sliding block 14 The inside that fixed plate 8 makes fixed plate 8 enter transformer outer container 2 is moved, it, will after fixed plate 8 to be slid into the inside of transformer outer container 2 4 slide downward of movable doorboard seals 2 front of transformer outer container, and at this moment transformer outer container 2 and power shell 1 are fixed, When fixed, the first sliding block 11 of 2 side of transformer outer container is stuck in the surface of slide bar 3, then on the surface of slide bar 3 mobile first Sliding block 11 then rotates screw rod 13 by nut 12, makes the one of screw rod 13 to the corresponding position of the groove that opens up with 3 surface of slide bar End is against the inside that the first sliding block 11 is fixed on to slide bar 3 in the groove on 3 surface of slide bar, and at this moment, transformer outer container 2 is then fixed On power shell 1, after transformer outer container 2 and power transformer main body 6 are fixed, then it can star fan 9, make fan The wind of 9 blowouts is by ventilating duct 7 from air outlet 5 punishes the surface for being dissipated to power transformer main body 6 to power transformer main body 6 To the effect of heat dissipation, here it is the working principles of the unshielded insulation output power supply transformer of the three winding.

Although the utility model is described in detail with reference to the foregoing embodiments, come for those skilled in the art Say, it is still possible to modify the technical solutions described in the foregoing embodiments, or to part of technical characteristic into Row equivalent replacement, within the spirit and principle of the utility model, any modification, equivalent replacement, improvement and so on should all It is included within the scope of protection of this utility model.
