Electric power element installation device with dust screen and electronic control unit

Abstract

An electric power element installation device with a dust screen and an electronic control unit provided by the invention comprises a crossbeam (13) configured to fix the electric power element (131) and a cooling module configured to connect with the end of the crossbeam (13). The cooling module includes a housing rack (7) fixed at the end of the crossbeam (13) and a fan device (2) configured to rotate with respect to the housing rack (7). The fan device (2) includes an installation housing (17) provided with an airflow flowing port (171), a fan motor (221) installed in the housing and a fan blade (22) configured to dynamically connect with the fan motor (221). The dust screen (172) is arranged in the airflow flowing port (171) at the left side of the fan blade (22). The dust screen (172) is arranged to prevent the installation housing (17) from dust, avoid adhering the dust to the fan blade (22) and avoid the influence on the normal operation of the fan blade (22) because of overstocking of the dust for a long time.

Description

technical field [0001] The invention relates to the field of electric power, in particular to a power electric component installation device with a dust-proof net and an electronic control device. Background technique [0002] In the field of power and electricity, some electrical components such as relay switches, overload protectors, circuit breakers and other devices often generate heat during use. This heating phenomenon will not directly affect the safety of electricity use and equipment installation in a short period of time, but the long-term heating and overheating phenomenon will have an adverse effect on the mechanical structure of the device's shell, bracket, etc., and cause the mechanical strength of these structures to fail. , resulting in serious accidents. [0003] In cooling devices for these devices, fans uniformly installed on the box body are often used to centrally dissipate heat from the internal space containing these devices. This plays a good role i...

Problems solved by technology

However, it is still difficult to play a targeted role in the cooling and heat dissipation of the main heat-generating devices that are significantly higher than other devices during use.

Moreover, some centralized heat dissipation equipment is likely to cause difficulties in the maintenance of such main power devices, which may interfere with the positioning and installation of such power components during operation, and may also cause interference to the operation of such power devices
