[0001] The invention relates to the technical field of power transformation test, in particular to a novel insulating rod head special for power transformation test. Background Art

[0002] Substation testing refers to a series of tests and inspections of substation equipment in power systems. It is an effective means of analyzing and diagnosing the health of electrical equipment and is of great significance to ensuring the safety of power grids and equipment. When conducting outdoor tests on substation equipment such as switches and transformers, a key step is to connect the test wires of the test instrument to the equipment leads at a high position. However, since the connection part is usually located at a high position, some existing insulating rod heads are inconvenient to use. Specifically, the metal rings of these insulating rod heads and the connection between the wires are often not completely closed, resulting in unreliable hanging and easy loosening or falling off. This not only affects the accuracy of the test data, but may also cause personal injury due to falling. Therefore, a new insulating rod head specially designed for substation testing is proposed.

After the test is completed, the insulating rod body 2, the connecting plate, the test mechanism, the blocking mechanism and the connecting rod in the transmission mechanism can be moved down to restore to their original position, thereby reducing the overall volume of the device and facilitating the transportation of the device.

[0026] Working principle: When in use, according to the actual height of the metal wire, the motor 91 is started, and the output end of the motor 91 rotates forward to drive the main gear 93 to rotate forward, and then the forward rotation of the main gear 93 drives the one-way gear 2 83 to rotate (the one-way gear 1 71 is in a non-rotating state), which in turn drives the reciprocating screw rod 2 81 to rotate, and then the rotation of the reciprocating screw rod 2 81 drives the lifting plate 2 82 to move upward, so that the insulating rod body 2 3, the connecting plate 4, the semi-enclosed metal ring 51, the metal rod 52, the crocodile metal clip 53, the connecting wire 54, the reciprocating screw rod 1 61, the lifting plate 1 62, the top rod 63 and the connecting rod 72 are moved to a suitable height; Next, the moving device allows the metal wire to enter from the opening of the semi-enclosed metal ring 51, completing the contact between the arc of the semi-enclosed metal ring 51 and the metal wire.

Then, the metal wire can be moved out of the opening. Then, the motor 91 can be started. The forward rotation of the output end of the motor 91 can drive the main gear 93 to rotate forward, so that the insulating rod body 2 3, the connecting plate 4, the semi-closed metal ring 51, the metal rod 52, the crocodile metal clip 53, the connecting wire 54, the reciprocating screw rod 1 61, the lifting plate 1 62, the top rod 63 and the connecting rod 72 move down and return to their original positions, thereby reducing the overall volume of the device.
