Problems solved by technology

However, the disadvantage of this patent is that the high-voltage bushing and the low-voltage bushing are all above the heat sink, and the higher temperature will cause the insulation aging of the high-voltage and low-voltage plug-in accessories and reduce the insulation performance.
At the same time, the existing pole-mounted transformers have poor heat dissipation performance and are difficult to cope with long-term high-load operation

Abstract

The invention provides an integrated pole-mounted transformer and an integrated pole-mounted voltage transformation system, and relates to the field of transformers. The integrated pole-mounted voltage transformation system comprises an installation platform and the integrated pole-mounted transformer, the integrated pole-mounted transformer comprises an oil tank, a transformer body, an auxiliarycooling device, a high-voltage sleeve, a low-voltage sleeve and a temperature monitoring device, the auxiliary cooling device comprises multiple cooling assemblies and multiple heat conduction guidingpieces, the heat conduction guiding pieces are wound around the peripheral face of the oil tank, the cooling assemblies are fixedly connected with the heat conduction guiding pieces in a one-to-one correspondence mode, according to each cooling assembly, one end of each heat conduction guiding piece extends into the oil tank and makes contact with a heat conduction medium, and the other end of each heat conduction guiding piece is fixedly connected with the corresponding cooling assembly so that heat of the heat conduction media can be transferred to the cooling assemblies for cooling. Compared with the prior art, the integrated pole-mounted transformer has a good cooling effect and meanwhile can monitor internal temperature in real time.

Description

technical field [0001] The invention relates to the field of transformers, in particular to an integrated pole-mounted transformer and an integrated pole-mounted transformer system. Background technique [0002] With the progress of the society, at present, the State Grid has designed and configured a large number of pole-mounted transformers in the distribution area. This transformer is installed between two poles with a distance of 2.5 meters. There are two kinds of installation methods: formal installation and formal installation. High-voltage side configuration: 10kV fuse, lightning arrester, high-voltage connecting cable. Low-voltage side configuration: low-voltage connecting cables, integrated distribution box, and 3 low-voltage outlets. [0003] Most of the pole-mounted transformers currently used are general power transformers. Including: fuel tank, transformer oil, device body, top cover, high-voltage bushing, low-voltage bushing, etc. Corrugated sheets are arran...
