Description

Technical Field

[0001] This utility model relates to the field of transformer technology, specifically to a suspended housing for a high vibration-resistant small-capacity transformer. Background Technology

[0002] Transformers often vibrate during operation due to various factors, such as electromagnetic forces and mechanical rotation. These vibrations not only generate noise but can also affect the connection stability and service life of internal components over time. For suspended transformers, the unique installation method makes vibration problems potentially more pronounced, and traditional casing structures are insufficient to effectively cope with the effects of vibration.

[0003] Therefore, the shortcomings of existing transformer casings are:

[0004] (1) Insufficient vibration resistance. Traditional transformer shell materials mainly consider strength and protection, but have insufficient vibration absorption capacity. When faced with continuous vibration, the metal shell is prone to conduction of vibration and has almost no vibration reduction effect.

[0005] (2) The suspension device has a single function. The existing suspension transformer has a single function, usually only serving as support and fixation, without considering buffering. This causes the vibration generated by the transformer to be directly transmitted to the installation structure, which not only generates noise but also causes metal fatigue at the suspension point.

[0006] (3) Insufficient protection of internal components: Existing technology cannot effectively suppress the impact of vibration on delicate components such as internal windings and insulation layers of transformers. Long-term vibration can cause winding deformation and insulation layer damage, thereby affecting transformer performance and service life, and increasing the operational risks of the power system.

[0007] (4) Lack of adaptability to complex operating conditions, and poor performance under complex climatic and geographical conditions. For example, in earthquake-prone areas, the existing shell structure is difficult to withstand the strong vibration impact of earthquakes, which may damage the internal components of the transformer. In harsh environments such as high temperature and humidity, vibration may accelerate the corrosion and aging of the shell and internal components, and the existing technology has no corresponding countermeasures.

[0008] The purpose of this invention is to provide a suspended housing for a high vibration-resistant, small-capacity transformer, in order to solve the problems mentioned in the background art.

[0009] To achieve the above objectives, this utility model provides the following technical solution: a suspended housing for a high vibration-resistant small-capacity transformer, comprising a housing body, the housing body including an upper end face, a lower end face, a left end face, a right end face and a bottom end face, the upper end face, the lower end face, the left end face, the right end face and the bottom end face being integrally formed, the upper end face being provided with three hanging ears, the transformer being housed inside the housing body, the gap between the transformer and the housing body being filled with potting compound, the open end of the housing body being provided with a cover plate, the cover plate being sealed to the housing body.

[0010] Preferably, the hanging ear includes a base plate and a folding plate, and the folding plate is provided with hanging holes.

[0011] Compared with the prior art, the beneficial effects of this utility model are: by setting the hanging ears on the outer shell body, the outer shell is easy to install, reducing the installation process and making it more stable after installation; by filling the outer shell body 1 with potting glue and vacuum sealing, the transformer can adapt to harsh environments.
