Fan heat dissipation system drive control device applied to rail traffic

Abstract

The invention discloses a fan heat dissipation system drive control device applied to rail traffic. The fan heat dissipation system drive control device applied to rail traffic comprises a fan body, wherein the front end of the fan body is fixedly connected to a protective cover; the left end and the right end of the protective cover are fixedly connected to lock catch mechanisms; the lower end ofthe protective cover is fixedly connected to a junction box; the lower end of the junction box is fixedly connected to a connecting wire; one end, away from the junction box, of the connecting wire is fixedly connected to a control apparatus; the left end and the right end of the control apparatus are movably connected to connecting plates; a mounting housing is fixedly connected between the twoconnecting plates; the front end of the mounting housing is blocked with a protective shell; and the control apparatus is packaged by the mounting housing, the protective shell and the two connectingplates. According to the fan heat dissipation system drive control device applied to rail traffic disclosed by the invention, the fan is mounted and dismounted conveniently, so that the control apparatus can be protected, and therefore, the control apparatus can be prevented from being touched by mistake, safety is high and the service life is high.

Description

technical field [0001] The invention relates to the technical field of drive control of fan cooling systems, in particular to a drive control device applied to fan cooling systems in rail transit. Background technique [0002] As we all know, rail transit vehicles are a mobile vehicle, the main AC power of the busbar of the air-conditioning unit is provided by the vehicle engine, the emergency AC main power is provided by batteries and inverters, and the secondary circuit power is DC power. Under these harsh environmental conditions such as three different power supply signals interleaving with each other, grid harmonic interference, and large power wave peaks, the quality and control methods of all low-voltage components of the air-conditioning unit must be reliable and stable. At present, the control systems of rail transit vehicle fans (subways, locomotives) mostly use touch screens or multi-selection switches as the operation panels of fan units, which are matched with c...

Problems solved by technology

[0003] However, in the existing fan cooling system drive control device, the fan assembly is inconvenient to install and difficult to disassemble and maintain, resulting in inconvenient use. At the same time, it is used to control The touch screen of the fan assembly lacks protection and is easily damaged. At the same time, the touch screen is easy to be accidentally touched, resulting in irregular changes in the use of current, which will reduce the service life of the fan assembly and the control device, and reduce the use and installability of the fan assembly. Therefore, we propose A drive control device applied in rail transit fan cooling system
