Embodiment

[0022] Such as figure 1 As shown, the dry-type transformer box structure of the present invention is a cuboid or a cube, including twelve supporting frames, and the plates forming the six sides of the box are correspondingly fixed to the supporting frames. Among them, the four sides of the left side, the right side, the top side and the bottom side are scalable, the left side and the top side, the left side and the bottom side, the right side and the top side, and the right side and the bottom side. The support frame shared by the end faces adopts a telescopic structure. The plates on these four sides expand and contract with the expansion and contraction of the support frame, so that the overall volume of the box structure can be adjusted, which is convenient for transportation to the transformer after assembly in the factory and other places. Use location for installation. The state of the box after shrinkage is as follows figure 2 shown.

Abstract

The invention relates to a box body structure of a dry transformer. In the box body structure, support frameworks which are shared by a left side surface and a top end surface, the left side surface and a bottom end surface, a right side surface and a top end surface and the right side surface and the bottom end surface all employ telescopic support frameworks, and plates forming the left side surface, the right side surface, the top end surface and the bottom end surface of the box body structures stretches with the stretching of the telescopic support frameworks. Since the support frameworks with telescopic and adjustable lengths are arranged, the box body structure is convenient to transmit, load and unload; and the box body structure is convenient to splice, is high in visuality and good in ventilation and heat dissipation.

Description

technical field [0001] The invention relates to a box body structure of a dry-type transformer. Background technique [0002] Transformers are mainly used to convert the voltage of the 10kV high-voltage power grid into 400V civil electricity, and are widely used in industrial and mining enterprises, office buildings, residential quarters and other places. Since dry-type transformers are insulated by epoxy resin casting, unlike conventional oil-immersed transformers, which have the risk of oil leakage, they have various advantages such as safe use and maintenance-free, and are more and more widely used in various fields. Most of the transformers used in newly developed residential areas are dry-type transformers. [0003] Dry-type transformers are generally installed in power distribution rooms. In order to prevent the intrusion of foreign matter and ensure the safety of operators, dry-type transformers are often equipped with protective casings. The protective shell is ge...
