Embodiment Construction

[0026] In order to facilitate the understanding of the present invention, the present invention will be described more fully below with reference to the associated drawings. Preferred embodiments of the invention are shown in the accompanying drawings. However, the present invention can be embodied in many different forms and is not limited to the embodiments described herein. On the contrary, these embodiments are provided to make the understanding of the disclosure of the present invention more thorough and comprehensive.

[0027] It should be noted that when an element is referred to as being “fixed” to another element, it can be directly on the other element or there can also be an intervening element. When an element is referred to as being "connected to" another element, it can be directly connected to the other element or intervening elements may also be present. The terms "vertical," "horizontal," "left," "right," and similar expressions are used herein for purposes ...

Abstract

The invention relates to a transformer with a reinforced radiator, which comprises a box body, a damping bracket and a radiator; the damping bracket comprises a cross supporting rod, a diagonal supporting rod and a damper, and the damping bracket can generate tiny deformation in a vibrating environment; under the earthquake effect, the radiator can be vibrated within a certain scale along with thevibrating bracket, thereby avoiding the radiator dropping from the box body for the rupture of the rigid connection. Moreover, the box body, the radiator and the damping bracket can be formed to be astructure which is similar to a tuning quality damper, and the tuning quality damper can eliminate energy and absorb shock, thus the overall power response is reduced. Furthermore, the flexible connection between the radiator and the holding cavity is free. Therefore, the radiator in the vibrating process can also be connected with the holding cavity all the time, so as to avoid oil leakage and other phenomenon. Therefore, the anti-seismic property of the transformer with the reinforced radiator can be effectively promoted.

Description

technical field [0001] The invention relates to the technical field of power transmission and transformation, in particular to a radiator-reinforced transformer. Background technique [0002] Large-scale transformers are key substation equipment in power transmission and transformation projects. They play the role of increasing the voltage at the power station and reducing the voltage at the user end, thereby reducing the loss of electric energy in the transmission link. Large-scale transformers are usually composed of iron cores and coils, boxes filled with mineral oil and oil conservators, risers, radiators, bushings of different voltage levels and other components. [0003] However, in geological disasters such as earthquakes, transformers installed outdoors are vulnerable to different types of damage, resulting in the outage of power transmission and transformation projects and the paralysis of the power grid, resulting in immeasurable losses. Among them, the radiator i...
