Problems solved by technology

Usually, the meter installation cabinet is installed outdoors. When it encounters rainy weather, rainwater can easily penetrate into the cabinet, making the environment inside the cabinet humid and affecting the normal operation of the meter.
[0003] In addition, the hot summer will easily lead to an increase in the temperature inside the cabinet, which may burn out the meter
Moreover, the electric meter installation cabinet in the prior art is easily damaged by lightning

Abstract

The invention relates to an outdoor electric meter installation cabinet, comprising a cabinet body, wherein a cabinet door is arranged on the cabinet body. The outdoor electric meter installation cabinet is characterized in that a rubber seal ring is arranged on the periphery of the inner side of the cabinet door; a temperature sensor and a humidity sensor are arranged in the cabinet body; the temperature sensor and the humidity sensor are connected to a microcontroller, and an output end of the microcontroller is connected with an electromagnetic relay; a drainage fan is also arranged in the cabinet body communicates with the outside by virtue of a drainage pipeline, a one-way valve and a silica gel layer are sequentially arranged in the drainage pipeline along a drainage wind direction, and the drainage fan is connected to a power supply source by virtue of the electromagnetic relay; and the bottom of the cabinet body is connected with the ground by virtue of an ground resistance.

Description

technical field [0001] The invention belongs to the technical field of electric power equipment, and relates to an electric meter protection device, in particular to an outdoor electric meter installation cabinet. Background technique [0002] The meter installation cabinet is a power system auxiliary equipment used to install the meter. Usually, the electric meter installation cabinet is installed outdoors. When it encounters rainy weather, the rainwater easily penetrates into the cabinet, making the environment in the cabinet humid and affecting the normal operation of the electric meter. [0003] In addition, the hot summer will easily lead to an increase in the temperature inside the cabinet, which may burn out the electric meter. Moreover, the electric meter installation cabinet in the prior art is easily damaged by lightning strikes. This is the weak point of prior art. [0004] Therefore, aiming at the defects in the prior art, it is very necessary to provide and d...
