device power supply devices monitoring and accounting of electric power dc traction network of railways

摘要

the utility model relates to a secondary source of nutrition, преобразующим high-voltage voltage primary power source current низковольтное voltageand can be used for power equipment monitoring and recording of electrical energy employed in the traction network of railways 3.3 kv dc voltage.;purpose of utility model is the strengthening of the protection of the device from the power feed voltage surges present in the traction network.;this goal is achieved by the fact that in the pulse power unit with galvanic interchange used n identical cells, united consistently on входам and exitseach cell consists of an electrically stabilized pulse transducer caused by dc voltage in the input voltage and the depth of its a стабилитрshe connected parallel to its front.;submitted by the technical solution has improved the security of the device from the influence of the traction network voltage surges.;the device can be used in railway traction sub stations was nearing completion электровозах and dc voltage 3.3 kw as power source equipment monitoring and recording of electrical energy.
