摘要： A partial discharge test power supply system for an extra high voltage transformer comprises: an electric motor (1); an intermediate frequency generator (2) driven by the electric motor and outputting an intermediate frequency voltage; a middle transformer (9) receiving the intermediate frequency voltage and outputting a test voltage to be applied to a test sample (11) by a generator outlet (5); a low-voltage compensating reactor (8) connected between the intermediate frequency generator and the middle transformer; a high-voltage compensating reactor (10) connected between the middle transformer and the sample; wherein the electric motor and the intermediate frequency generator are arranged in a metal housing (100). The system also includes the following filters: a filter (a) arranged in the excitation circuit of the intermediate frequency generator, a filter (b) arranged between the high-voltage compensating reactor and the sample and a filter (c) arranged between the generator outlet and the low-voltage compensating reactor. The system provides a simple and reliable power source system with little background interference for the extra high voltage partial discharge tests.

摘要： Disclosed is a method for determining the spatial location of a conducting wire and an aerial earth wire of a power transmission line, so as to solve the problem that the method in the prior art is not applicable to determining the spatial location of the conducting wire and the aerial earth wire of the conventional power transmission line with respect to lightning shielding failures. In the present invention, according to the physical locations of the conducting wires and aerial earth wires, the power transmission line shielding efficiency is calculated based on that the corresponding lightning shielding failure trip rate is zero when the exposure arc is zero, thus providing designing and operating units with a reliable analytical method for preventing lightning shielding failures, and meanwhile working out the shielding efficiency of the conducting wire of each phase more accurately, so as to analyze the structural relations between the aerial earth wires and conducting wires to determine the lightning protection effect of the whole power transmission line. The present invention provides a supplementary analytical method of the shielding efficiency of the existing power transmission lines.
