Dry-type Transformer Vibration Mitigation Device

Abstract

The objective of the invention is to provide a dry type transformer vibration relieving device. The dry type transformer vibration relieving device includes a transformer fixing seat, and a pluralityof vibration reduction seats which are arranged side by side and support the transformer fixing seat; each vibration reduction seat includes an upper base having an upper groove formed in a lower endthereof, a lower base having a lower groove formed in a lower end thereof and an upper end positioned in the upper groove, and a plurality of vibration reduction devices; each vibration reduction device includes a through hole formed in an upper end of the lower base and communicating with the lower groove, an upper convex block arranged on a top surface of the upper groove and facing the throughhole, a stepped elastic post arranged in the lower groove and having a small end passing through the through hole and supporting a lower end of the upper convex block, and a pressing disc having a fixing rod arranged on an upper end thereof; the pressing disc presses a big end of the stepped elastic post, and the fixing rod passes through the stepped elastic post and is connected to a lower end ofthe upper convex block. When the dry type transformer vibration relieving device is used, vibration is reduction and isolated via the stepped elastic posts of the vibration reduction device, and vibration noise of the dry type transformer will not transmitted to a power distribution room to disturb residents.

Description

technical field [0001] The invention relates to the field of transformer installation, in particular to a dry-type transformer vibration mitigation device. Background technique [0002] Dry-type transformers are widely used in local lighting, high-rise buildings, airports, wharf CNC mechanical equipment and other places. Simply put, dry-type transformers refer to transformers whose iron core and windings are not immersed in insulating oil; traditional dry-type transformers usually pass through the base Rigidly fixed on the ground, there is a problem that the vibration noise will be transmitted to the power distribution room during use and cause disturbance to the residents; therefore, a dry-type transformer vibration mitigation device that will not transmit the vibration noise of the dry-type transformer to the power distribution room and cause disturbance to the residents is designed. , has become an urgent problem to be solved. Contents of the invention [0003] The pur...
