Description

Technical Field

[0001] The utility model relates to the field of high-voltage and high-current connection, in particular to a universally adjustable high-voltage and high-current connection device. Background Art

[0002] Electrical large-capacity tests often involve electrical connections between test pieces and test equipment. The corresponding voltage of this connection can reach 800kV and above, and the corresponding current can reach 80kA and above. In this high-voltage and high-current environment, there are problems with high-voltage insulation and electrodynamics, and the reliability requirements for electrical connections are relatively high. Traditional solutions usually use copper braided wire soft connections or cable connections, and then fix them with insulating ropes. The above methods have the following problems during implementation: Different from low-voltage test pieces, high-voltage test pieces are large in size, and the insulating rope cannot find a force point at high altitudes; if the insulating rope is pulled to the ground, the length can reach 5 meters or even longer. In the case of the extremely large electrodynamics generated in large-capacity tests, it is difficult to keep the soft connection or cable fixed, and the insulating rope may even be torn off, causing an accident.
