Abstract

The invention belongs to the technical field of prefabricated substations, and discloses a low-noise prefabricated substation. The prefabricated substation comprises a shell, a mounting plate is fixedly connected to the bottom of the shell, mounting holes are formed in the four corners of the top of the mounting plate, heat dissipation nets are embedded in the left side and the right side of the shell, a left-right machine body are arranged in the shell, and a fixing block is fixedly connected to the bottom of the machine body. The machine body operates and vibrates, a guide device makes the fixing block and the machine body move up and down in the vertical direction, and with the up-and-down movement of the machine body, the limitation and guidance of a sliding block and a horizontal groove make two inclined rods drive two connecting blocks to get close to each other and get away from each other, so that force in the vertical direction is converted into force in the horizontal direction, stress is counteracted through mutual cooperation of a first-stage vibration and noise reduction assembly and a second-stage vibration and noise reduction assembly, vibration is reduced, rigid collision between the machine body and the shell is red cuced, and noise is lowered.

Description

technical field [0001] The invention relates to the technical field of prefabricated substations, more specifically, to a low-noise prefabricated substation. Background technique [0002] The prefabricated substation is electrically connected through cables or busbars. All high and low voltage power distribution devices and transformers are conventional stereotyped products. The prefabricated substation has the advantages of small size, small footprint, light weight, low cost, and reliability. "Box type substation" or "prefabricated substation". [0003] Prefabricated substations generally include a shell and a body. The body is located inside the shell, the core of the entire substation. The body will vibrate during operation and collide with the shell 1 rigidly, which will not only generate noise but also shorten the service life of the body. . Contents of the invention [0004] 1. Technical problems to be solved [0005] In view of the problems existing in the prior ...
