Abstract

The invention discloses a noise reduction vibration isolator used for high voltage electric power container installation, and solves the problems that the damping effect is poor and the center of gravity of equipment is easy to be out-of-position existing in an existing device. A lower supporting seat is formed by a rectangular base plate (8), a left front lower arc-shaped baffle plate (10), a left rear lower arc-shaped baffle plate (16), a right front lower arc-shaped baffle plate (6) and a right rear lower arc-shaped baffle plate (17), an upper supporting seat is formed by a rectangular topplate (4), an upper left arc-shaped baffle plate (12) and an upper right arc-shaped baffle plate (13), and the outer side faces of the arc-shaped baffle plates of the upper supporting seat are matchedwith the arc-shaped inner side faces of the lower arc-shaped baffle plates, so that the concentricity of the upper supporting seat and the lower supporting seat is guaranteed; the upper supporting seat and the lower supporting seat are in a floating state through a damper spring (11), a left lower telescopic rod (15), a right lower telescopic rod (14) and a spring upper cover (2) between the upper supporting seat and the lower supporting seat. Through concentric cooperation of the upper floating supporting seat and the lower floating supporting seat, horizontal installation of the vibration isolator is guaranteed, and the problem that the center of gravity of electric power equipment is out-of-position is avoided.

Description

technical field [0001] The invention relates to a mounting support for electric power equipment, in particular to a mounting support for power capacitor equipment. Background technique [0002] In the power system, especially in the UHV DC transmission system, a large number of high-voltage power capacitors are used. Due to the existence of a large number of harmonics in the UHV DC transmission system, when the harmonic current flows through the power capacitor, the internal electrodes and insulating materials of the power capacitor will vibrate under the influence of the distorted electric field generated by the harmonics, causing the power capacitor The whole also vibrates at the same time. As the vibration intensifies, the sound emitted by the power capacitor will become louder, creating noise pollution. Therefore, in the installation of power capacitors in substations, how to reduce the overall vibration of power capacitors is the subject of vibration isolation devices...
