INTERNAL LEAD WIRE SEALING TYPE MEASURING POWER TRANSFORMER

The utility model relates to an internal lead wire sealing type measuring power transformer. A measuring meter cavity and a sealing type lead wire cavity are arranged in an oil conservator, a secondary connection is formed by a mutual inductor through a low-voltage outgoing line of a lead wire, and the secondary connection is penetrated through a communicating pipe or a conduit pipe and leads to the sealing type lead wire cavity. A measuring meter is wired by the sealing type lead wire cavity, an electric source point is not easy to find by an electricity thief, and thus, the phenomenon of electricity theft can be effectively prevented. The major structure of the transformer does not need to be changed, and the utility model has the advantages of simple structure, convenient installation, accurate measuring and safety.
