Abstract

The invention relates to a vibration damping and impact resisting device for electric power equipment, which comprises a peripheral noise reduction structure (1), a bottom vibration damping and noise reduction structure (2) and a buffer structure, and is characterized in that the peripheral noise reduction structure (1) comprises a closed cover body (11) formed by sound absorption partition boards in an enclosing manner, an air inlet assembly (12) and a noise reduction door (13) which are arranged at the front side of the closed cover body (11) and a plurality of air exhaust assemblies (14) arranged at the top surface of the closed cover body (11), the bottom vibration damping and noise reduction structure (2) comprises a cylinder body (21), a guide rod (22), a base (23), a spring (24), a shearing force buffer rod (25), a buffer sleeve (26), a spherical hinge (27) and a spherical hinge base (28), and the buffer structure comprises a mounting screw (41), a buffer tube (42) and a buffer tube mounting base (43). The vibration damping and impact resisting device is simple in structure, convenient to install and maintain and good in ventilation and heat dissipation, not only can effectively reduce noise pollutions of the electric power equipment, but also has a certain disaster preventing and impact resisting effect.

Description

technical field [0001] The invention belongs to the technical field of vibration reduction and noise reduction, in particular to a vibration reduction and anti-shock device for electric equipment. Background technique [0002] Distribution substations and substations are important power places. Due to the continuous expansion of cities and the needs of urban grid transformation, some distribution substations and substations must be built in commercial and residential areas. With the enhancement of people's awareness of environmental protection, the noise problems of high and low voltage cabinets, switch cabinets, power equipment, etc. have been highly valued by the power sector and power equipment manufacturers. Also, damage to power equipment caused by external natural disasters often occurs. For example, the impact damage to power equipment caused by earthquakes is also hoped to be effectively prevented while reducing noise. [0003] Although the noise generated by most e...
