As personnel enter the transformer.卩 Check that the air is thin and the space is small, there is a certain degree of safety concerns. The internal variation process of the voltage device has its specific process stage characteristics. Generally, the abnormality of the conventional voltage device needs to be repeated until the internal electro-discharge element discharges a gas-induced alarm and other serious stages to make people aware, and it is difficult to achieve the purpose of precaution and warning 20 M356995. . [New content] 5 The main purpose of this creation is to provide an improved transformer structure, which can provide on-line inspection function of transformers, which can be applied to transformers with insulating fluids, such as oil-immersed transformers or gas-insulated transformers. - In order to achieve the above objectives, the improved transformer structure of the present invention includes a variable pressure peripheral, a hole cover, and at least one transparent viewing window.

The side of the dust collector housing 11 is provided with a manhole 112 for the person to enter the inside of the whole device. In this embodiment, the position is close to the bottom surface, and the side where the manhole iu is located is the operation hole setting surface. The orifice of the manhole ΐ 2 is covered by a manhole cover 12. Specifically, a transparent observation window 13a to 13d is embedded in the four side faces of the transformer casing 11, and the transparent observation windows 13a to 13d are disposed at approximately the middle and the top surface of each side. The position on the top surface is convenient for people to observe in a standing position without bending over and down. The position and size of the transparent viewing windows 13a to 13d affect the extent of the inside of the transformer, and in this example, the inner faces of the respective transformer casings are designed to be viewed in each window. As shown in Fig. 3, taking one of the transparent viewing windows i3a as an example, it is possible to observe the area surrounded by the broken line toward the inner surface of the transformer casing 11, and it is preferable to observe the complete area of the corresponding inner surface. In the present embodiment, the transparent viewing window is made of glass, and the transparent plastic material such as acrylic can also be used. Since the four sides of the embodiment are provided with a transparent observation window 13a~13d for observing the inside of the transformer 20 M356995, it is ensured that the inside of the transformer can be completely inspected without observing the dead angle. ★ Of course, it is also possible to set a transparent viewing window only for special observation needs. 'Generally, the part that you might want to observe is 〇ltc or non-voltage top changer (NVTC), coil, core, insulating paper, The insulating support wood, the joint between the coils, the inside of the sleeve, and the like. Therefore, with this creation, for example, the analysis of the insulating oil can be used to initially judge whether the internal abnormality of the equipment is abnormal or not, mainly by observing the variation of the color of the insulating oil. In addition, if the insulation covered by the copper wire is overcurrent, it will also change color. 15 20 The practicality of this creation lies in the fact that the transparent material is not conductive and has no magnetic line cutting. In terms of electrical insulation (4), it is the original iron material of the Han Dynasty. Outside the P-knife (9), in terms of strength considerations, since the proportion of the area occupied by the transparent viewing window is only one part of the side of the outer casing, there is no damage due to insufficient strength. In addition, due to the specific specifications of the operating temperature of the transformer, the transparent material is also guaranteed to not cause undesirable variations at this specification temperature. / Figure 4 is a plan view of a transformer of another preferred embodiment. In addition to the above-mentioned embodiment, the fixed transparent viewing window (3) L ' may also correspond to the position on the outer casing U that is particularly required to be repaired: the hand-opening type 'reveloping transparent viewing window' is also the same Transparent hand hole 31 with observation function. This is usually the case, for example, in the high voltage wiring section of the coil. It is known from the loading that the main (4) person M in the setting department to visually observe the preliminary abnormal inspection is a very convenient design. When the visual view J has a different shape, it can be further checked for further physical inspection. Therefore, the creation of this work has the effect of on-line inspection, and the equipment is predicted in advance without power failure, unpacking, and leakage of 6 M356995 oil. Abnormal.
