Description

Technical Field

[0001] This utility model relates to the field of transformer noise reduction technology, and more specifically, to a dual noise reduction and heat dissipation type oil-immersed transformer. Background Technology

[0002] Distribution transformers are one of the important equipment in the power supply and distribution systems of industrial and mining enterprises and civil buildings. They reduce the high voltage bushing voltage of 10 noise reduction device (6) kV or 35kV network voltage to the 230 / 400V bus voltage used by users. Except for small capacity transformers, the low voltage windings of oil-immersed transformers generally adopt a cylindrical structure with copper foil winding around the shaft.

[0003] Existing oil-immersed transformers have high operating efficiency due to internal rotation, resulting in significant noise generation. While existing oil-immersed transformers use noise-reducing protective covers for noise reduction, these covers offer high sealing performance but low heat dissipation. Furthermore, the lack of protective and vibration-damping components at the bottom of existing oil-immersed transformers makes it difficult to eliminate noise generated by vibrations during operation.

Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] As attached Figure 1-4 As shown, this utility model provides a dual noise reduction and heat dissipation type oil-immersed transformer, including a base plate 1. A dual noise reduction and heat dissipation transformer protection device 2 is provided on the upper end of the base plate 1. The dual noise reduction and heat dissipation transformer protection device 2 includes a heat dissipation and noise reduction isolation component 21 and a shock absorption and protection component 22. The shock absorption and protection component 22 is disposed inside the heat dissipation and noise reduction isolation component 21, and the lower end of the heat dissipation and noise reduction isolation component 21 is installed on the upper end of the base plate 1.

[0021] The heat dissipation and noise reduction isolation component 21 includes: a noise reduction protective cover 212, a heat dissipation and dust prevention fan 215, a filter outer protective frame 214, an upper sealing positioning plate 213, and an electric hydraulic cylinder 211. The lower end of the electric hydraulic cylinder 211 is installed on the upper side of the base plate 1, and the output end of the electric hydraulic cylinder 211 is installed on the lower side of the upper sealing positioning plate 213. The lower end of the upper sealing positioning plate 213 is installed on the upper end of the noise reduction protective cover 212. The lower end of the noise reduction protective cover 212 is detachably connected to the upper end of the base plate 1. An oil-immersed transformer body 216 is installed on the upper end of the base plate 1.

[0022] The shock absorption and protection assembly 22 includes: a shock absorption and protection column 227, an extended shock absorption positioning crossbar 228, a shock absorption damping spring 220, a rotating shock absorption mating roller shaft 229, a shock absorber sliding limit seat 2201, a bottom protection plate 223, a docking mounting groove 224, a docking mounting block 225, a shock absorption and protection column assembly 222, and a welding plate 221. The lower end of the welding plate 221 is installed on the upper end of the base plate 1, the lower end of the shock absorption and protection column assembly 222 is installed on the upper end of the welding plate 221, the upper end of the shock absorption and protection column assembly 222 is installed on the lower end of the bottom protection plate 223, and the docking mounting groove 224 is formed in the bottom. The upper end of the protective plate 223 and the lower end of the mating mounting block 225 are detachably installed inside the mating mounting groove 224. The upper and lower ends of the installation shock-absorbing protective column 227 are installed on the front side of the extended shock-absorbing positioning crossbar 228. The front end of the installation shock-absorbing protective column 227 is installed on the outer side wall of the oil-immersed transformer body 216.

The lower end of the shock-absorbing damping spring 220 is movably installed on the upper end of the shock absorber sliding limit seat 2201.

[0023] The specific implementation method is as follows: When using this utility model, the noise reduction protective cover 212 set at the upper end needs to be moved up and down by the electric hydraulic cylinder 211 set on the side. After the noise reduction protective cover 212 moves down, it can seal and cover the outer wall of the oil-immersed transformer body 216. After the outer wall of the oil-immersed transformer body 216 is covered, the two sets of heat dissipation and dust prevention fans 215 set at the front and rear ends of the noise reduction protective cover 212 can perform dust prevention blowing. After the heat dissipation and dust prevention fans 215 complete the heat dissipation work inside the noise reduction protective cover 212, the noise reduction protective cover 212 can simultaneously block and protect the outer wall of the oil-immersed transformer body 216, which is a problem of large rotation noise of the oil-immersed transformer body 216. When in use, the transformer body 216 can be protected against shock by the shock-absorbing and protective components 22 at its lower end. When in use, the shock-absorbing and protective components 22 can protect the side of the oil-immersed transformer body 216 from downward movement by the cooperation of the side-mounted shock-absorbing and protective columns 227, the extended shock-absorbing and positioning crossbar 228, the shock-absorbing damping spring 220, the rotating shock-absorbing and cooperating rolling shaft 229, and the shock absorber sliding limit seat 2201. In addition, the lower end of the oil-immersed transformer body 216 is protected against shock by multiple sets of shock-absorbing and protective columns 222, which greatly improves the shock-absorbing and protective safety of the entire device and the stability of use and transportation. It effectively solves the problem of increased noise and difficulty in ensuring the safety of use caused by impact and shaking during use.

[0024] The working principle of this utility model is as follows: When using this utility model, the noise reduction protective cover 212 set at the upper end needs to be moved up and down by the electric hydraulic cylinder 211 set on the side. After the noise reduction protective cover 212 moves down, it can seal and cover the outer wall of the oil-immersed transformer body 216. After the outer wall of the oil-immersed transformer body 216 is covered, the two sets of heat dissipation and dust prevention fans 215 set at the front and rear ends of the noise reduction protective cover 212 can perform dust prevention blowing. After the heat dissipation and dust prevention fans 215 complete the heat dissipation work inside the noise reduction protective cover 212, the noise reduction protective cover 212 can simultaneously block and protect the outer wall of the oil-immersed transformer body 216, which is a problem of large rotation noise of the oil-immersed transformer body 216. When the oil-immersed transformer body 216 is in use, the shock absorption and protection component 22 set at the lower end can perform shock absorption and protection.
