Description

Technical Field

[0001] The utility model relates to the technical field of transformer wire trough equipment, in particular to a transformer wire trough structure. Background Art

[0002] In order to facilitate the slot winding operation of the coil on the transformer core, it is often necessary to install a transformer wire slot structure on the transformer core. The utility model patent with patent application number CN202020914014.5 discloses a new structure of a transformer wire slot. By setting a telescopic spring, the device can be effectively telescopically engaged and fixed. In daily use, the wires can be telescopically engaged according to the use requirements, thereby effectively improving the use efficiency of the device. By setting a second telescopic rod, the device can be effectively telescopically adjusted. In daily use, the device can be telescopically adjusted on both sides according to the use requirements, thereby effectively improving the use efficiency of the device. According to the technical solution disclosed by the utility model, when the existing transformer wire slot equipment is in use, on the one hand, when multi-layer winding operation is required, once the insulation layer of the coil is damaged, it is easy to cause the coil to short-circuit, which is not conducive to ensuring the working safety of the transformer. On the other hand, the coil is prone to generate a lot of heat during operation, which is easy to accelerate the aging of the coil or even cause damage, which is not conducive to ensuring the service life of the transformer.

[0003] Therefore, how to design a transformer cable trough structure has become our current problem to be solved. Utility Model Content

The utility model has a reasonable design and is relatively convenient to use, and is suitable for the installation and fixation of transformer coils.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a transformer wire trough structure, comprising a transformer core and a coil, a transformer wire trough assembly is installed on the top of the transformer core, the transformer wire trough assembly comprises an outer partition and an inner partition, a limit assembly is installed on the inner partition, the limit assembly comprises a slide groove and a guide rod, a locking assembly is installed on the outer partition, the locking assembly comprises a guide pin and a second spring piece, a heat dissipation assembly is installed on the outer side of the transformer core, the heat dissipation assembly comprises a first spring piece and silicone grease.

[0006] Furthermore, the outer partition and the inner partition are both welded to the outer side of the transformer core, and the inner partition is evenly distributed on the transformer core.

[0007] Furthermore, the outer partitions are respectively installed at the bottom and the top of the inner partition, and wire slots are formed between the outer partitions, the inner partitions and the transformer core, and the coils are wound on the inner sides of the wire slots.

[0008] Furthermore, the slide groove is opened on the inner side of the inner partition, the top end of the guide rod is clamped on the bottom of the coil, and the bottom end of the guide rod passes through the slide groove and is clamped on the top of the coil.

[0009] Furthermore, the silicone grease is installed on the inner side of the wire slot, and the silicone grease is wrapped on the outer side of the coil.

[0010] Furthermore, one end of the spring sheet 1 is welded to the top and bottom of the inner partition and the outer partition respectively, and the other end of the spring sheet 1 is clamped on the outer side of the coil.

[0011] Furthermore, a slot is provided on the inner side of the outer partition, one end of the guide pin is clamped on the inner side of the slot, and the other end of the guide pin passes through the slot and extends to the outer side of the coil.

[0012] Furthermore, one end of the second spring piece is welded to the inner wall of the slot, and the other end of the second spring piece is clamped on the outer side of one end of the guide pin.

When the transformer wire slot structure is in use, when the first layer of coils are being wound, the guide rod can slide up and down on the inner side of the slide slot, so that the first layer of coils can pass over the guide rod and be wound on the outer side of the transformer core. When the second layer of coils are being wound, the two ends of the guide rod are limited to each other by the coils, so that a certain gap is generated between the coils, and silicone grease is wrapped on the outer side of the coils. The outer side of the coil is fixed by a spring sheet.

[0014] 2. When the transformer wire slot structure is in use, the heat generated by the coil during operation can be quickly transferred to the inner partition and the outer partition through the silicone grease. At the same time, a pair of springs are used to block the silicone grease to prevent the silicone grease from overflowing due to vibration, thereby ensuring that the silicone grease is in full contact with the coil. The inner and outer partitions are used to increase the heat dissipation area, thereby effectively improving the heat dissipation efficiency of the coil, reducing the working temperature of the coil, ensuring the working safety of the coil, and thus ensuring the working life of the transformer.
