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

Abstract

A noise-reducing power electrical component installation device comprises a beam (13) used for fixing a power electrical component (131), and a cooling assembly connected with the end of the beam (13). The cooling assembly comprises a shell frame (7) fixed to the end of the beam (13), and a fan device (2) capable of rotating relative to the shell frame (7). The fan device (2) comprises an installation shell (17) provided with air flow openings (171), a fan motor (221) installed inside the installation shell, and fan blades (22) in power connection with the fan motor (221). A sound insulation box (217) is arranged around the fan motor (221) to reduce the noise generated during operation of the fan motor (221), the sound insulation box (217) is made of metal materials and can achieve a cooling effect, and the side face of the sound insulation box (217) is provided with multiple air vents used for communicating the fan motor (221) with the outside air.

Description

technical field [0001] The invention relates to the field of electric power, in particular to a power electric component installation device capable of reducing noise. 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 in improving the working envir...
