Shockproof dry type transformer and method

Abstract

The invention discloses a shockproof dry type transformer and a method. The shockproof dry type transformer comprises a transformer body, a clamping mechanism, a shockproof cylinder and the like, wherein the transformer body comprises an iron core, a winding and a shell; the clamping mechanism clamps the iron core and comprises a first upper clamp, a second upper clamp, a first lower clamp and a second lower clamp; the shockproof cylinder is arranged outside the shell in a surrounding mode and is formed by an outer cylinder and an inner cylinder; grooves are arranged in the inner wall of the outer cylinder along a circumferential direction, leaf springs and elastic pressing strips are arranged in the groove in a surrounding mode, and each elastic pressing strip seals the corresponding groove and extends out of the groove; the grooves communicate with a compressed gas tank through a gas joint; the inner cylinder is attached to the elastic pressing strips, and shockproof racks are longitudinally arranged on the inner wall. According to the method, the combined action of the clamping mechanism and shockproof pressing blocks is adopted, so that shaking of the iron core is prevented; primary buffering is achieved by the inner cylinder, and secondary buffering is achieved by the outer cylinder. According to the shockproof dry type transformer and the method, a problem of unreasonabledesign of the shockproof structure is solved, shaking of the iron core or loosening of a coil is avoided, and the use safety and the service life of the dry type transformer are improved.

Description

technical field [0001] The invention relates to a transformer, in particular to a shockproof dry-type transformer and a method thereof. Background technique [0002] A transformer is a device for exchanging AC voltage, alternating current and impedance. It consists of an iron core (or magnetic core) and a coil. The coil has two or more windings. The winding connected to the power supply is called the primary coil, and the remaining windings are called the secondary coil. There are many types of transformers. Among them, dry-type transformers refer to transformers whose iron core and windings are not immersed in insulating oil. However, in the existing dry-type transformers, the design of the anti-shock structure is not reasonable enough. The iron core is easily affected by vibrations and shakes around or the coils are easily affected by vibrations and loosen, which can easily cause damage to the transformer, which not only affects the safety of dry-type transformers, Use a...

Problems solved by technology

However, the existing dry-type transformer has an unreasonable anti-shock structure design. The iron core is easily affected by vibration and shakes around or the coil is easily affected by vibration and loosens, which can easily cause damage to the transformer, which not only affects the safety of the dry-type transformer, Also increases operating and maintenance costs
