Outdoor electric power dampproof metering box

Abstract

The invention discloses an outdoor electric power dampproof metering box. The outdoor electric power dampproof metering box includes a housing, the lower end of the housing is provided with a pedestal, and the housing is divided into a positive pressure working cavity, a gas storage cavity and a gas collection cavity through separation plates; the gas storage cavity is internally provided with an air compressor and an gas collection bottle which are communicated through a pipeline, an exhaust port of the gas collection bottle extends into the positive pressure working cavity, and the exhaust port of the gas collection bottle is provided with a flow control valve; and at least a layer of waterproof breathable film is installed in the gas collection cavity, and the gas collection cavity is connected with an air inlet of the air compressor through a pipeline. The outdoor electric power dampproof metering box provided by the invention separates from moisture in the air through the waterproof breathable film, dry gas is stored in the gas collection bottle through the air compressor, and gas in the gas collection bottle is continuously poured into the positive pressure working cavity, so that untreated air cannot enter into a box body, thereby ensuring dryness in the box body, effectively avoiding a working element corrosion phenomenon caused by too large humidity, and ensuring continuous and stable operation of the metering box.

Description

technical field [0001] The invention relates to the technical field of electric power equipment, in particular to an outdoor power moisture-proof metering box. Background technique [0002] The metering box is a kind of distribution box. It is a low-voltage power distribution device composed of switchgear, measuring instruments, protective appliances and auxiliary equipment in a closed or semi-closed metal cabinet or on a screen according to the requirements of electrical wiring. In each hair, distribution and substation. [0003] Many electronic components configured in the metering box have high requirements for the dry and humidity environment of the air in the box. The current metering box is generally not equipped with a device for drying the gas in the box. For the metering box that has been used in a high temperature and high humidity environment for a long time, its internal The components in the metering box are easily damaged, causing it to fail to work normally. ...

Problems solved by technology

[0003] Many electronic components configured in the metering box have high requirements for the dry and humidity environment of the air in the box. The current metering box is generally not equipped with a device for drying the gas in the box. For the metering box that has been used in a high temperature and high humidity environment for a long time, its internal The components in the metering box are easily damaged, causing it to fail to work normally. In rainy weather, rainwater is easy to seep into the metering box, causing short circuit and damage to the electrical components in the metering box, which affects the normal use of the wiring box.

[0004] Chinese patent CN203103789U discloses an outdoor rain-proof refrigerator, which is composed of a distribution box body, a door frame of the distribution box, a door of the distribution box, a rainproof eaves, and a rainproof cover. The rain-proof eaves protruding from the cabinet body of the distribution box are equipped with rain-proof covers on both sides of the top of the cabinet body of the distribution box, which has a certain effect of preventing rain and snow, but the rain-proof eaves are set too wide and the settings of the rain-proof covers are uneven. It will increase the volume and materials of the cabinet, which not only increases the manufacturing cost, but also brings inconvenience to handling and storage. If the rain-proof eaves are too narrow, the rainwater may still flow to the door frame along the rain-proof eaves, and enter the cabinet from the door frame. There is still a chance of damage to the components
