Embodiment Construction

[0015] A connection structure between an oil-immersed transformer low-voltage terminal and a conductive rod, see image 3 and Figure 4 , the connection structure includes a conductive rod 1 and a terminal 2 . The upper part of the conductive rod is threaded, and the lower part is a polished rod. There are two mounting holes radially penetrating on the upper part of the conductive rod, and a terminal hole matching the mounting hole is provided on the terminal, and a screw thread suitable for the upper part of the conductive rod is also provided in the terminal. It is threadedly fitted on the conductive rod, and locked by two fastening bolts 3 arranged in the installation hole and the terminal hole; the terminal removes the clamping part of the traditional installation fastening bolt. An adjusting gasket 6 is sleeved on the conductive rod, and the adjusting gasket is located below the wiring head. The connecting head compresses the porcelain bottle 5 on the case cover 4 by a...

Abstract

The invention discloses a connecting structure of a low-voltage connector lug of an oil-immersed transformer and a conducting rod of the oil-immersed transformer. The connecting structure comprises the conducting rod and the connector lug. Radially-through installation holes are formed in the upper portion of the conducting rod, connector lug holes matched with the installation holes are formed in the connector lug, the conducting rod is sleeved with the connector lug and the connector lug and the conducting rod are locked through fastening bolts arranged in the installation holes and the connector lug holes. An adjusting gasket is arranged on the conducting rod in a sleeved mode and the adjusting gasket is located below the connector lug. The connecting structure is reliable to install and firm in connection, greatly saves raw materials, meets production requirements and meets the requirements of national policy.

Description

technical field [0001] The invention belongs to the field of transformer manufacturing, in particular to a connection structure between an oil-immersed transformer low-voltage lug and a conductive rod. Background technique [0002] For a long time, the low-voltage terminals and conductive rods of oil-immersed transformers have followed the unified design of Shenyang Transformer Research Institute. figure 1 It is a schematic diagram of the connection structure of the traditional oil-immersed transformer low-voltage terminal and the conductive rod. figure 2 yes figure 1 top view. During assembling, the conductive rod 11 is installed from the bottom of the case cover 14, and the upper part of the case cover is covered with a low-pressure porcelain bottle 15, and then compressed with a flat pad and a compression nut 16 to play the role of compression and sealing. Put it into the terminal 12, and finally lock it with the fastening bolt 13 to complete the assembly, and the cla...
