Transformer cabinet based on self-feedback uniform heat dissipation

Abstract

The invention discloses a transformer cabinet based on self-feedback uniform heat dissipation. The invention belongs to the field of transformer equipment, a special composite heat dissipation sheet can be additionally arranged on a surface of an existing transformer oil tank, matched lifting heat-absorbing balloons are introduced while the heat dissipation of the oil tank is greatly improved, a self-feedback heat dissipation mechanism arranged on the composite heat dissipation sheet is used for sensing the heat distribution condition on the transformer oil tank; phase expansion is carried outaccording to heat distribution; more lifting heat-absorbing balloons are attracted through the magnetic attraction effect to be in contact for heat transfer; the transfer of heat to the lifting heat-absorbing balloons is accelerated; after absorbing enough heat, the lifting heat-absorbing balloons automatically rise to a cup-shaped outer heat dissipation shell to transfer the heat to the outside;the lifting heat-absorbing balloons serve as intermediate media to play a role in temporary heat storage, a heat conduction bridge between the transformer oil tank and the outside is built, the uniform and efficient heat dissipation and cooling of the transformer oil tank are achieved, and, therefore, the working stability and safety of a transformer are improved.

Description

technical field [0001] The invention relates to the field of transformer equipment, more specifically, to a transformer cabinet based on self-feedback and uniform heat dissipation. Background technique [0002] The prefabricated substation is electrically connected through cables or busbars. All high and low voltage power distribution devices and transformers are conventional stereotyped products. The prefabricated substation has the advantages of small size, small footprint, light weight, low cost, and reliability. "Box-type substation" or "prefabricated substation. It is a kind of high-voltage switchgear, distribution transformer and low-voltage power distribution device. It is a factory prefabricated indoor and outdoor compact power distribution equipment arranged according to a certain wiring scheme. That is to organically combine functions such as transformer step-down and low-voltage power distribution, and install them in a moisture-proof, rust-proof, dust-proof, rode...

AI Technical Summary

Problems solved by technology

For small-capacity transformers, smooth oil tank surface is enough to cool the oil; for medium-capacity transformers, the surface of the oil tank should be wrinkled to increase the heat dissipation surface, or a fin or flat tube radiator should be installed to make the oil circulate in the radiator A radiation radiator should be installed on the surface of the large-capacity transformer oil tank, but the heat released by the transformer during operation is not uniform enough, which may easily lead to local overheating inside, which will cause the decomposition of transformer oil and generate gas, which will affect the normal use of the transformer
