Изобретение относитс к области защиты преобразователей.This invention relates to the field of converter protection.
Известно устройство дл защиты вентильных преобразователей, содержащее автоматический выключатель 1,A device for protecting valve converters is known, comprising a circuit breaker 1,
Недостатком этого устройства вл етс невысока надежность.A disadvantage of this device is low reliability.
Наиболее близким к предлагаемому по технической сущности и достигаемому результату вл етс устройство дл защиты вентильных преобразователей , содержащее автоматические выключатели , полюса которых включены в силовые цепи преобразовател 2 .Closest to the proposed technical essence and the achieved result is a device for protection of valve converters, containing circuit breakers, the poles of which are included in the power circuits of the converter 2.
Однако это устройство имеет недостаточную надежность.However, this device has insufficient reliability.
С целью повышени надежности в предлагаемом устройстве дл защиты полюса выключателей включены в плечи преобразовател и блокированы между собой.In order to increase reliability, in the proposed device for protection of the switch poles are included in the converter arms and are interlocked.
На фиг. 1 представлена схема защиты преобразовател от аварий со стороны посто нного тока; на фиг, 2 - устройство дл защиты реверсивного преобразовател от аварий в уравнительном контуре и со стороны посто нного тока; на фиг. 3 - устройство дл защиты реверсивного преобразовател от -аварий со стороны посто нного и переменного тока и внутренних и с неполным отделением вентилей от потенциала нагрузки; на фиг. 4 - защита реверсивного преобразовател от аварий со стороны посто нного и переменного тока и внутренних и с полным отделением вентилей от потенциала нагрузки питающей сети.FIG. 1 shows the protection circuit of the converter against accidents on the DC side; FIG. 2 shows a device for protecting a reversible converter against accidents in an equalizing circuit and on the direct current side; in fig. 3 is a device for protecting a reversing converter from -avarii on the side of direct and alternating current and internal and with incomplete separation of the valves from the load potential; in fig. 4 - protection of the reversing converter from accidents from the direct and alternating current both internal and with complete separation of the valves from the load potential of the supply network.

По.пюса одного или нескольких автоматических выключателей, используемых дл защиты вентильного преобразовател , устанавливают в плечах преобразовательной схемы и механически One or several circuit breakers used to protect the converter are installed in the arms of the converter circuit and mechanically
5 или электрически блокируют между собой . При этом требуемый номинальный ток выключател уменьшаетс до 0,58 тока нагрузки, а благодар одновременному размыканию по.люсов, сто щих 5 or electrically blocked between each other. At the same time, the required rated current of the circuit breaker is reduced to 0.58 of the load current, and due to the simultaneous disconnection of positive currents
0 во всех цеп х, подключенных параллельно плечу, в котором протекал ток, исключаетс возможность приложени напр жени дуги к каким-либо вентил м .0 in all circuits connected parallel to the arm in which the current was flowing, the possibility of applying arc voltage to any valves is excluded.
