Electric power metering device

Abstract

The invention discloses an electric power metering device which comprises an electric power metering box, a protective shell, a gear motor and a lift controller. Protective shell sliding rails are arranged on corresponding positions on the two sides of the electric power metering box. The protective shell and the protective shell sliding rails are in sliding fit. The protective shell is provided with a rack. The rack is in sliding fit with a rack sliding rail arranged on the upper portion of the electric power metering box and is meshed with a driving gear arranged on the gear motor. A set of semiconductor refrigeration sheets, a set of air inlet fans, a set of electric energy meters, a line-in terminal, a line-out terminal, a set of switches and a radiating drying controller are arranged in the electric power metering box. The protective shell and the electric power metering box in the electric power metering device cooperate to ascend and descend, and consequently the electric power metering box can be well protected; the whole device can be arranged outdoors, has a rainproof function, can resist dampness, has a high temperature heat dissipation function and is wide in applicable range and long in service life.

Description

technical field [0001] The invention relates to the field of power metering equipment, in particular to a power metering device. Background technique [0002] In the process of residential electricity consumption, the power metering device is indispensable. The power metering device can record the amount of electricity used by each household. It is an important power device. However, ordinary power metering devices do not have waterproof functions, and power metering devices are in Bungalows in remote areas are often installed outdoors. At the same time, the current power metering device does not have a good heat dissipation function. The heat in the device cannot be dissipated in time, and it is prone to failure after a long time. The metering device is not highly resistant to theft. Contents of the invention [0003] The purpose of the present invention is to provide an electric power metering device to solve the problems raised in the background art above. [0004] In...
