Description

Technical Field

[0001] The present application relates to the technical field of zero-sealing busbars, and in particular to a transformer winding outgoing line zero-sealing busbar fixing structure. Background Art

[0002] A transformer is a device that uses the principle of electromagnetic induction to change the AC voltage. Its main components are the primary coil, the secondary coil, and the iron core (magnetic core). The main functions include: voltage conversion, current conversion, impedance conversion, isolation, voltage stabilization (magnetic saturation transformer), etc. Transformers are basic equipment for power transmission and distribution, and are widely used in industries such as industry, agriculture, transportation, and urban communities. In power transformers, the fixed structure of the winding outlet zero-sealing busbar is an important link in the stable operation of the transformer. However, the traditional zero-sealing busbar usually uses screws to directly fix the winding group, which not only increases the complexity of installation and maintenance, but also may cause the screws to loosen after long-term operation, causing the wires to loosen, thereby affecting the stable operation of the transformer. Secondly, the fixed structure in the prior art is not ideal for preventing wire vibration and displacement, which may cause noise and vibration during the operation of the transformer, affecting its service life.

DETAILED DESCRIPTION

[0018] The following is combined with Figure 1-3 This application is described in further detail.

[0019] The embodiment of the present application discloses a transformer winding outlet sealing busbar fixing structure. Figure 1-Figure 2 , including a busbar bracket 1, both sides of the bottom of the busbar bracket 1 are provided with fixing plates 2, the fixing plate 2 is welded with a connecting plate 7 at one end close to the busbar bracket 1 as an integral structure, the connecting plate 7 is connected to the bottom wall of the busbar bracket 1 by bolts 9, and a plurality of through holes are equidistantly provided on the surface of the fixing plate 2, which can be installed and fixed to the transformer through the fixing plate 2, a group of supporting busbars 3 are symmetrically provided at both ends of the busbar bracket 1, and a reinforcing block 6 for support is connected between the supporting busbar 3 and the inner wall of the busbar bracket 1 to ensure stability, and a plurality of outlet holes 5 are equidistantly provided inside the supporting busbar 3 for wiring the outlet wires of the transformer winding, and the wires can be positioned.

[0020] like Figure 3 As shown, a group of insulating wire clamp bases 10 are fixedly provided at an equal distance on the top of the busbar support 1, and a matching insulating wire clamp baffle 4 is provided on the insulating wire clamp base 10. The insulating wire clamp baffle 4 and the insulating wire clamp base 10 are arranged in combination, and mounting holes 13 are opened on both sides of the top of the insulating wire clamp baffle 4. The internal thread of the mounting hole 13 is connected with a connecting screw 14, and a rotating block 15 is fixed on the top of the connecting screw 14. The end of the connecting screw 14 away from the rotating block 15 is threadedly adapted to the insulating wire clamp base 10, so rotating the rotating block 15 can drive the connecting screw 14 to rotate in the inner thread of the insulating wire clamp base 10.

[0021] One end of the connecting screw 14 passes through the insulating wire clamp base 10 and extends to the bottom of the busbar support 1, and a matching positioning nut 8 is threadedly connected to the outer wall of the bottom end of the connecting screw 14. When the connecting screw 14 is rotated, the insulating wire clamp baffle 4 can be driven close to the top of the insulating wire clamp base 10, so as to facilitate the adjustment of the appropriate fixed spacing according to the outlet requirements;

[0022] A plurality of fixing holes 11 are equidistantly provided inside the insulating wire clamp base 10, and a plurality of retaining blocks 12 adapted to the fixing holes 11 are equidistantly fixed to the bottom of the insulating wire clamp baffle 4. When the retaining blocks 12 are close to the fixing holes 11, the top of the wire can be limited to further ensure the stability of the output wire.

[0023] The implementation principle of a transformer winding outlet sealing busbar fixing structure in an embodiment of the present application is as follows: when in use, the connecting plate 7 is fixed to the bottom of the busbar bracket 1 by bolts 9 in advance, and then installed and fixed to the transformer winding outlet through the fixing plate 2, and then the wire is wired through the outlet hole 5 inside the supporting busbar 3. The outlet hole 5 is set with a larger aperture to facilitate flexible adjustment of the wiring position, and the wire is passed through between the insulating wire clamp baffle 4 and the insulating wire clamp base 10 and is located in the fixing hole 11, and then the rotating block 15 is rotated to drive the connecting screw 14 to move downward on the inner thread of the insulating wire clamp base 10, and then the insulating wire clamp baffle 4 is pushed downward to the top of the insulating wire clamp base 10. At this time, the stop block 12 is close to the top of the wire to limit it to prevent the wire from falling off, which has a good positioning effect. The spacing between the insulating wire clamp baffle 4 and the insulating wire clamp base 10 can be adjusted according to the use requirements, and then the bottom of the connecting screw 14 is fixed by the positioning nut 8 to complete the positioning. The overall structure is simple and ingenious, and it is easy to operate and use.
