Detailed Description
The present invention will be further described with reference to the following drawings and examples, and embodiments of the present invention include, but are not limited to, the following examples.
Example 1
As shown in FIGS. 1-2, the water-cooling type pulse transformer comprises a transformer body and an annular water-cooling device. The annular water cooling device is arranged at the bottom of the transformer main body, the annular water cooling device and the transformer main body are in contact, and a gap is filled between the annular water cooling device and the transformer main body through high-thermal-conductivity silica gel, so that the annular water cooling device and the transformer main body are connected together. The annular water cooling device is matched with the overall shape of the transformer main body to cool the transformer main body. The transformer main body and the annular water cooling device are arranged in a transformer shell and encapsulated by epoxy resin. In this embodiment, epoxy resin with thermal conductivity (1W/(m k) temperature (-45-260 ℃) and insulation strength (volts/mil: 460) is selected for encapsulation.
Specifically, in this embodiment, the transformer body includes a magnetic ring, a winding, and a high-temperature insulating film.
Specifically, in this embodiment, the magnetic ring is wound with a high-temperature insulating film in a manner that: and the adhesive tape is wound by layers for a circle along the magnetic ring according to the length distance of one third of the width of the adhesive tape. Preferably, the high-temperature insulating film with the width of 19mm and the thickness of 0.08mm is selected to be wound along the circumference of the magnetic ring. Because of the high voltage of the transformer, the problem of voltage resistance is specially solved, and the winding high-temperature insulating film and the encapsulating epoxy resin are used for high-voltage insulating treatment. The high-temperature insulating film is a polytetrafluoroethylene tape.
In this embodiment, the winding is sleeved on the magnetic ring and is coaxial with the magnetic ring. In the embodiment, a multistrand triple insulated wire with a heat-resisting grade B, a breakdown voltage of more than 15kv and low high-frequency loss is selected as a winding and is uniformly and tightly wound on a magnetic ring. In order to ensure the reliability of the voltage resistance, the secondary side is wound firstly, then the positive side is wound, and the whole magnetic ring and the secondary side winding are subjected to voltage resistance insulation treatment.
After the winding is disposed on the magnetic ring, the winding process is performed again outside the winding with a high-temperature insulating film in the same manner as described above. So that the transformer body is safely insulated.
In this embodiment, the annular water cooling device is made of copper tube, and the shape and size of the annular water cooling device are matched with those of the transformer main body, that is, the annular water cooling device is an annular water cooling pipeline. And a water inlet pipe and a water outlet pipe which are communicated with the water inlet and the water outlet of the annular water cooling device are reserved on the transformer shell, so that the temperature is reduced during work.
It is worth mentioning that the high-voltage end of the transformer body must be far away from the primary coil of the transformer and the water inlet and outlet of the cooling forming copper tube to prevent the generation of electric arc.
Example 2
The present embodiment is different from embodiment 1 in that the structure of the annular water cooling device is further designed.
In this embodiment, the annular water cooling device includes two independent first water-cooling pipes and second water-cooling pipe, and first water-cooling pipe and second water-cooling pipe all coil and become the annular. The first water-cooling pipe and the second water-cooling pipe are arranged on the same plane in a staggered mode. That is, the first water-cooling pipe is coiled with a plurality of annular rings, and the second water-cooling pipe is also coiled with a plurality of annular rings. An annular ring of a second water-cooling pipe is arranged between two annular rings connected with the first water-cooling pipe.
Furthermore, a water inlet of the first water-cooling pipe is positioned on the outer ring of the annular ring, and a water outlet of the first water-cooling pipe is positioned on the inner ring of the annular ring. The water inlet of the second water-cooling pipe is positioned on the inner ring of the annular ring, and the water outlet of the second water-cooling pipe is positioned on the outer ring of the annular ring.
The water cooling device formed by the simple annular pipeline in the embodiment 1 has the disadvantages that the cooling water exchanges heat with the pulse transformer from the beginning of water inlet, the cooling effect is gradually reduced along with the running of the cooling water, the cooling is not uniform enough, the temperature of the part cooled after the transformer is relatively high, and the damage possibility of the transformer is relatively high. The structure of this embodiment is compared in the water cooling plant that simple ring pipeline formed, and its advantage lies in: the cooling water enters the annular water cooling device from two directions, namely from the outer ring and from the inner ring, so that the cooling is more uniform.
According to the above embodiment, alright realize the utility model discloses well. It is worth to say that, on the premise of the above structural design, in order to solve the same technical problem, even if some insubstantial changes or retouching are made in the utility model, the essence of the adopted technical scheme is still the same as the utility model, so it should be in the protection scope of the utility model.
