Abstract

The invention provides a lightning protection dry-type transformer, and relates to the technical field of transformers. The lightning protection dry-type transformer comprises a body and at least onelightning arrester arranged on the body, wherein one end of each lightning arrester is connected with a high-voltage input current lead of one phase of the body and the head end of a winding of the winding, and the other end of each lightning arrester is grounded. In the lightning protection dry-type transformer, the lightning arrester has less wiring, so that the wiring is simple; and, the lightning protection dry-type transformer can be directly arranged in a power distribution room instead of a shell, so that the cost can be saved.

Description

technical field [0001] The invention relates to the technical field of transformers, in particular to a lightning protection dry-type transformer. Background technique [0002] Dry-type transformers are generally used in power distribution rooms in residential quarters, office buildings, shopping malls or airports, etc., and are equipped with special enclosures. Generally, only by grounding the transformer to guide the current to the earth, without separate lightning protection measures, so Transformers are easily damaged or burned due to overcurrent and overvoltage. [0003] In view of the above problems, the prior art proposes a lightning protection scheme of placing a lightning rod on the top of the casing or installing a lightning rod on the body of the transformer. However, because the lightning rod is relatively high, the lightning protection scheme of placing the lightning rod on the top of the housing has relatively high requirements for the height of the power dist...
