Integrated power self-adaptive dehumidification device for 10kV ring main unit

Abstract

The invention discloses an integrated power self-adaptive dehumidification device for a 10kV ring main unit. A ring main unit is mounted above a foundation well, the foundation well is provided with an air inlet and an air outlet, the air inlet is provided with a fan, the air outlet is provided with an unpowered hood, a photovoltaic panel is laid on the ring main unit and is connected with an energy storage battery, the energy storage battery supplies power to the draught fan, a humidity sensor is arranged in the foundation well, and the humidity sensor is connected with the draught fan controller. According to the technical scheme, when the draught fan works, dry air is sucked into the foundation well from the outside through the U-shaped air inlet pipeline; when the air in the space reaches saturated air, the air is exhausted through the unpowered air cap, the work of ventilation and humidity reduction is achieved, and therefore the situation that moisture in the foundation well is too large and enters the ring main unit is effectively prevented.

Description

【Technical field】 [0001] The invention relates to the technical field of electric power engineering, in particular to the dehumidification technology of a ring cage. 【Background technique】 [0002] The 10kV ring net box is prone to condensation in autumn and winter, which will cause corrosion of the operating mechanism and electrical circuit contacts, and then cause malfunctions, refusals and other failures. In order to prevent the moisture in the foundation well of the ring net box from entering the interior of the ring net box, a fireproof board and sealant are used to prevent moisture from entering and exiting the cable at the bottom of the ring net box. The effect is not good, and the moisture will still penetrate into the interior of the ring net box and cause corrosion. . 【Content of invention】 [0003] In order to overcome the deficiencies in the prior art, the technical problem to be solved by the present invention is to provide a 10kV ring cage integrated power a...
