Embodiment Construction

[0031] The present invention will be described in further detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0032] The invention discloses an oil-immersed transformer with an oil detection device, such as figure 1 As shown, it includes a box body 1 with a box cover, an iron core 2, a coil 3 and a heat dissipation pipe. The iron core 2 is a single-frame double-stem column, and is arranged in the center of the box body 1 and is immersed in the oil body. Coils 3 are respectively wound on the single-frame and double-stem columns, and the coils 3 are led out of the box cover. The lead wires are respectively covered with high-voltage insulating bushings and low-voltage insulating bushings. The side wall of the box body 1 is provided with a cooling pipe. An oil inlet 4 is arranged under one side of the bo...

Abstract

Disclosed is an oil-immersed transformer equipped with an oil quality detection apparatus. The oil-immersed transformer comprises a box body with a box cover, an iron core, coils and a heat dissipation pipe; an oil inlet is formed in the lower part on one side of the box body while an oil outlet is formed in the upper part in the other side of the box body; the oil inlet is connected with an oil inlet pump while the oil outlet is connected with an external oil storage apparatus; an oil changing partition plate is arranged under the iron core; the oil changing partition plate is overlaid with the bottom of the box body; the oil quality detection apparatus is arranged on the upper part of the box cover; the oil quality detection apparatus is an inverted U-shaped hollow pipe; and the two ends of the oil quality detection apparatus are both connected with the interior of the box body. By virtue of the oil changing partition plate additionally arranged in the box body, oil changing can be completed rapidly and completely; the oil in the box body is stored in the oil storage apparatus, so that maintenance of the iron core and the oil changing operation can be facilitated, and cost is saved while overhaul efficiency is improved; and by virtue of the oil quality detection apparatus, the oil quality in the box body of the transformer can be detected in real time, and the transformer oil can be replaced and maintained in time.

Description

technical field [0001] The invention relates to the technical field of power transmission equipment, in particular to an oil-immersed transformer with an oil detection device. Background technique [0002] The main components of the transformer are the iron core and the coil, and the oil-immersed transformer is provided with cooling oil, which is used to cool the coil during operation. After the transformer has been used for a period of time, there will be dust accumulation, or there will be cracks and damages on the ceramic parts, or some parts will be damaged, and the contacts will be loose. The normal operation of the transformer, such as inspection and maintenance of the transformer core, etc., the transformer is generally installed at a high place, and the cooling oil needs to be discharged during the inspection and maintenance of the transformer. The operation is very inconvenient, and it is easy to cause damage to the equipment and casualties. [0003] For example, t...
