Abstract

The embodiment of the invention discloses a mobile impulse current generator and a method of use. The mobile impulse current generator comprises a shell, an impulse current generator body, a charging device, a charging protection resistor and a rotation base. Compared with the prior art, through arranging the impulse current generator body on the rotation base, the impulse current generator body and the charging device are integrated in one shell, the limit that a wave resistance frame is too wide in a transportation process and the impulse current generator body should just face the charging device in a test is broken, the mobile impulse current generator has the advantages of simple wire connection and convenient transportation, the requirement to a test field can be effectively reduced, the transportation cost is reduced and the testing efficiency is improved, the timely elimination of a hidden fault caused by a wrong test wire connection is helped, thus major power accidents are avoided, and the mobile impulse current generator and the method have large practical values.

Description

technical field [0001] The invention relates to the field of electric equipment testing, in particular to a movable impulse current generator and a usage method. Background technique [0002] In recent years, with the continuous development of the national economy and the continuous improvement of people's living standards, as well as the widespread application of electrical equipment and the increasing development of the aerospace industry, the gap in energy and power has become larger and larger. In order to meet the energy demand, the single-unit capacity of the grid has grown from 100MW to 200-300MW, the ultra-high voltage long-distance power transmission has increased significantly, and UHV power transmission projects have been launched continuously. At the same time, the single-unit expansion of the power grid also makes the transmission towers higher and higher, the distribution range of the power grid is getting larger and larger, and the requirements for the lightni...
