The electrical power element mounting device comprises a cross beam (13) and a cooling assembly, wherein the cross beam (13) is used for fixing an electrical power element (131); the cooling assembly is connected with the end part of the cross beam (13), and the cooling assembly comprises a shell body frame (7) which is fixed to the end part of the cross beam (13) and a fan device (2) which can rotate relative to the shell body frame (7); the fan device (2) comprises a mounting shell body (17) provided with an airflow flowing port (171), a fan motor (221) mounted inside the mounting shell body (17) and fan blades (22) which are in power connection with the fan motor (221); and a soundproof box (217) is arranged on the periphery of the fan motor (221) for reducing noise generated by the fan motor (221) in operation, the soundproof box (217) is made of metal materials and is capable of reducing temperature, and a plurality of ventilation holes are formed in the side surfaces of the soundproof box (217) for circulating 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 with contact indication and 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...

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
