Title: Compression-limited rubber packing to prevent excessive tightening when assembling transformer bushing
Inventor: KONG JUNG HO
IPC: H01F41/00
Filed: 2017-12-12
Abstract: The present invention relates to a compression-limited circular ring for preventing excessive tightening when assembling a bushing in a transformer. More specifically, a device that converts a high voltage transmitted from a power plant to a low voltage (220V, etc.) at the customer side is called a transformer, and transformers are divided into columnar transformers installed on poles and ground transformers installed on the ground. A terminal connecting a high-voltage primary side and a low-voltage secondary side voltage is connected to an internal winding of the transformer through the bushing, wherein the bushing uses packing to seal insulating oil inside the transformer. By inserting a compression suppressing means for suppressing compression in the packing to adjust a compressive force, a leakage of the insulating oil due to insufficient pressure, aging of packing rubber caused by contact with the outside, and breakage or non-compression of the packing by excessive pressure can be prevented. In addition, one or more inner protrusions and upper and lower protrusions are formed on the outside of a contact surface with the bushing or a contact surface of the packing, such that the pressure of the bushing and the packing can be limited, and a more firm sealing effect can be achieved.
