[0034] The utility model is further described below in conjunction with the accompanying drawings and embodiments:

[0035] Example 1: A high-efficiency energy-saving device for air-separation power system transformer, see Figures 1 to 4 , comprising a base plate 1, a guide bar 2 and a dry-type excitation transformer body 3;

[0036] The bottom plate 1 is fixed on the mounting platform; two guide bars 2 are symmetrically fixed on the mounting side of the bottom plate 1; the dry-type excitation transformer body 3 is arranged on the mounting side of the bottom plate 1; the dry-type excitation transformer body 3 is selected and used by the technicians of this profession according to the actual situation. The dry-type excitation transformer body 3 is a device that provides a three-phase AC excitation power supply for the generator excitation system. The excitation system converts the three-phase power supply into a DC power supply for the generator rotor through a thyristor to form a generator excitation magnetic field. The thyristor trigger angle is adjusted by the excitation system to achieve the purpose of adjusting the motor terminal voltage and reactive power, thereby achieving energy saving. Among them, two U-shaped clips 4 are symmetrically fixed at the bottom of the dry-type excitation transformer body 3, and the two U-shaped clips 4 are respectively engaged with the two guide bars 2; wherein, baffles 7 are fixed at the ends of the two guide bars 2, and the ends of the U-shaped clips 4 are limitedly engaged with the baffle 7; wherein, the U-shaped clips 4 and the guide bars 2 are fixedly engaged by bolts 5.

[0037] The utility model provides the guide strip 2, the U-shaped clamping strip 4 and the baffle 7, and has the advantages of positioning the dry-type excitation transformer body 3 by quickly clamping the guide strip 2 and the U-shaped clamping strip 4 when installing the dry-type excitation transformer body 3, and facilitating the installation of the bolt 5 by limiting the baffle 7, thereby solving the problem of needing to adjust the transformer position to correspond to the installation hole after placing the transformer, which is a relatively troublesome operation.

[0038] Specifically, the top of the guide bar 2 adopts a trapezoidal structure design, the top side of the guide bar 2 contacts and cooperates with the inner top wall of the U-shaped card bar 4, and the guide bar 2 is adapted to the inner cavity of the U-shaped card bar 4; when the top of the trapezoidal guide bar 2 is connected with the open end of the U-shaped card bar 4, it is more convenient to insert it into the opening of the U-shaped card bar 4.

[0039] Furthermore, the holes on both sides of the U-shaped clip 4 correspond to the holes on the guide bar 2; the bolt 5 passes through the holes on both sides of the U-shaped clip 4 and the holes on the guide bar 2, and a nut is screwed on the end through which the bolt 5 passes to fix the U-shaped clip 4 and the guide bar 2.

[0040] Furthermore, a limiting structure 6 is arranged on the bottom plate 1 at the front end of a guide bar 2;

[0041] The limiting structure 6 includes a fixing plate 601, a threaded rod 602, a rotating handle 603, a connecting plate 604 and a U-shaped retaining frame 605;

[0042] The fixing plate 601 is fixed on the bottom plate 1; the threaded rod 602 is threadedly inserted into the threaded hole on the fixing plate 601; the turning handle 603 is fixed on the outer end of the threaded rod 602; the connecting plate 604 is rotatably arranged on the inner end of the threaded rod 602; the U-shaped retaining frame 605 is fixed on the bottom side of the connecting plate 604; wherein, the U-shaped retaining frame 605 is clamped and matched with the guide strip 2, and the U-shaped retaining frame 605 is limitedly matched with the front end of the U-shaped clamping strip 4.

[0043] The utility model provides a fixing plate 601, a threaded rod 602, a rotating handle 603, a connecting plate 604 and a U-shaped retaining frame 605. After the U-shaped clamping strip 4 and the guide strip 2 are butted and limited, the rotating handle 603 drives the threaded rod 602 to rotate and push the connecting plate 604 and the U-shaped retaining frame 605 to move, so that the U-shaped retaining frame 605 blocks the front end of the U-shaped clamping strip 4, thereby further limiting the position of the U-shaped clamping strip 4 after the clamping.

[0044] Working principle: When using the device of the utility model, the bottom plate 1 is fixed on the installation platform. When installing the dry-type excitation transformer body 3, the dry-type excitation transformer body 3 is lifted and placed on the bottom plate 1 through an external lifting device. The inner cavity of the U-shaped clamping strip 4 corresponds to the guide strip 2 and docks, and pushes the dry-type excitation transformer body 3 horizontally. The U-shaped clamping strip 4 moves relative to the guide strip 2 until the end of the U-shaped clamping strip 4 contacts the baffle 7. The turning handle 603 drives the threaded rod 602 to rotate. The threaded rod 602 moves relative to the fixed plate 601 and pushes the connecting plate 604 and the U-shaped baffle 605 to move. The U-shaped baffle 605 moves along the guide strip 2 until the U-shaped baffle 605 blocks the front end of the U-shaped clamping strip 4. The bolt 5 passes through the holes opened on both sides of the U-shaped clamping strip 4 and the holes opened on the guide strip 2. The nut is screwed on the end through which the bolt 5 passes to fix the U-shaped clamping strip 4 and the guide strip 2.
