Problems solved by technology

In the existing pad scheme, there is a gap between the arc-shaped surface of the coil and the straight notch, which provides a deformation space for the deformation of the coil during the sudden short-circuit test, causing the low-voltage coil to sag inward, resulting in a sudden accident

Abstract

The invention discloses a cushion block for a marine medium voltage transformer. The cushion block comprises an cushion block body integrally formed by an insulating material, a groove is formed in a top end of the body, a clamping part is arranged at a bottom end of the body, a boss is arranged at a side end of the body, a bottom surface of the boss is higher than the bottom surface of the body, a cross section of the clamping part is arc-shaped, and an arc-shaped notch is formed in the middle. The cushion block disclosed by the invention has the advantages of being simple in structure and easy to realize, increasing the contact area of a coil, guaranteeing uniform stress of the coil under such special conditions as sudden short circuit and the like and reducing the deformation to the minimum, and moreover, the notch is formed in a position corresponding to the high voltage coil to evade an airway, so that the heat dissipation effect is greatly improved.

Description

technical field [0001] The invention relates to a transformer auxiliary part, in particular to a cushion block for a transformer. Background technique [0002] In transformers, pads are generally used to support and compress coils. At present, medium-voltage marine transformers are used more and more, and their requirements for sudden short-circuit resistance are very high. In the existing pad scheme, there is a gap between the arc-shaped surface of the coil and the straight notch, which provides a deformation space for the deformation of the coil during the sudden short-circuit test, causing the low-voltage coil to sag inward, resulting in a sudden accident. Contents of the invention [0003] Purpose of the invention: In view of the above problems, the purpose of the present invention is to provide a transformer block with simple structure and capable of resisting sudden short circuit. [0004] Technical solution: A spacer for medium-voltage transformers for ships, inc...
