Abstract

The invention belongs to the technical field of an electric control cabinet, and discloses a device for lowering the temperature by circulation wind for an electric appliance transmission control cabinet. The device for lowering the temperature by circulation wind for the electric appliance transmission control cabinet comprises a power distribution cabinet, wherein the two ends of the power distribution cabinet are provided with at least two ventilation pipelines through flanges; the ventilation pipelines are connected with three energy-saving fans with the power being lower than 1 kilowatt through the flanges; wind of a paper making fan enters the device from a position under the control cabinet through the ventilation pipelines; a small fan is arranged above the control cabinet and is used for exhausting hot air. The device provided by the invention has the advantages that the structure is simple; the operation is convenient; the ventilation efficiency is improved; the energy consumption of the original equipment is reduced. The circulation effect design can be met through the control cabinet; the continuous normal operation of a frequency converter electric appliance can be completely met; 90 percent of the fault caused by frequency converter heating is reduced; 50 percent of energy is saved; 30kw / h of energy can be saved by each control chamber.

Description

technical field [0001] The invention belongs to the technical field of electric control cabinets, and in particular relates to a cooling device for electric transmission control cabinets using circulating air. Background technique [0002] The electrical control cabinet for papermaking runs continuously for a long time. The control cabinet needs to be at 40°C, and more than 10 air conditioners with 10 horsepower are required to achieve the effect, which consumes a lot of energy. Now through air-conditioning refrigeration, to achieve the purpose of cooling, the method is single. [0003] To sum up, the problem existing in the prior art is that the purpose of cooling is achieved through air-conditioning refrigeration, and the method is single. Contents of the invention [0004] Aiming at the problems existing in the prior art, the present invention provides a device for reducing the temperature of an electrical transmission control cabinet by using circulating air.
