Abstract

The invention discloses an electric power engineering communication cabinet with heat dissipation, ventilation, dust prevention and dehumidification functions, relates to electric power engineering communication equipment, and aims to solve the problem that an existing communication cabinet is poor in heat dissipation, ventilation, dehumidification and dust prevention effects. An air inlet device, an air exhaust device and a filter screen are utilized to form a first ventilation and heat dissipation channel; a dehumidifier and an air outlet pipe are utilized to form a second ventilation and heat dissipation channel, and the two air channels can independently circulate and can also circulate in a crossed mode; meanwhile, a ventilation opening is formed in a partition plate of the exhaust device, and a ventilation fan is fixed to the second mounting chamber; multiple fixed stand columns and the baffle are located in the first mounting chamber, the spring is arranged between the limiting head and the baffle, and when the baffle moves, the spring is in a compressed state; the top end of the air outlet pipe is communicated with the interior of the cabinet body through the second air inlet, and the bottom end of the air outlet pipe is communicated with the air outlet of the dehumidifier; and an air inlet of the dehumidifier is communicated with the interior of the cabinet body through the second air outlet. The beneficial effects are that the ventilation and heat dissipation effects are good, and dehumidification and dust prevention can be realized.

Description

technical field [0001] The invention relates to a power engineering communication device. Background technique [0002] As an important equipment of the distribution network, the power engineering communication cabinet plays an important role in carrying communication equipment; and because the communication cabinet is often installed on the ground and connected to the cable trench, at the same time, the operation of the secondary equipment in the power engineering communication cabinet will A large amount of heat is generated. Therefore, the communication cabinet is in an environment of dust, high temperature and high humidity. Especially in rainy weather, there will be condensation or even water accumulation in the communication cabinet, which will easily cause a short circuit of the components and damage the internal components; [0003] In response to the above problems, three measures are mainly taken at present; the first measure is to rely on the operation and mainten...
