An electric energy metering box

Abstract

The invention discloses an electric energy metering box, which relates to the technical field of metering boxes. The key points of the technical solution include a metering box body, and a heat dissipation mechanism is arranged in the metering box body; the heat dissipation mechanism includes a combined transformer and a The heat dissipation expansion cavity on the combination transformer, the inner surface of the heat dissipation expansion cavity is provided with a plurality of arrays distributed and facing the inlet and outlet air holes of the combination transformer, and the heat dissipation expansion cavity is connected to drive the heat dissipation expansion cavity The expansion and contraction of the cavity is used as a driving part for heat dissipation treatment of the combined transformer. The driving part is sleeved on the combined transformer and used to absorb heat on the combined transformer. The invention achieves the purpose of significantly improving the heat dissipation performance of the electric energy metering box by absorbing the heat on the combined transformer through the heat dissipation telescopic cavity and the driving part, thereby enabling the combined transformer to have the effect of high stability in use.

Description

technical field [0001] The invention relates to the technical field of metering boxes, more specifically, it relates to an electric energy metering box. Background technique [0002] The electric energy metering box is a conventional metering device and an essential device before the power line enters the home; especially in recent years, with the development of the economy, the acceleration of urbanization and the acceleration of industrialization, especially the popularity of household appliances, the first The proportion of tertiary industries and residents' electricity consumption continues to increase, resulting in an increasing demand for electricity. The country has increased investment in power infrastructure including rural power grid transformation and urban transformation. Therefore, the electric energy metering box has a broad development space as a terminal meter for electric power products. . [0003] The Chinese patent application document with publication nu...
