(54) УСТРОЙСТВО ДЛЯ ПЛАВКИ ГОЛОЛЕДА БЕЗ ОТКЛЮЧЕНИЯ ПОТРЕБИТЕЛЯ(54) DEVICE FOR MELTING THE HOLODE WITHOUT A DISCONNECTION OF THE CONSUMER
1one
Изобретение относитс к электротехнике и может быть использовано на лини х электропередач,-проход щих в гололедоопасных районах.The invention relates to electrical engineering and can be used on power lines passing through icy dangerous areas.
Известно устройство дл плавки гололеда без отключени потребител при пофазной плавке гололеда токами наложени . - A device for melting ice without disconnecting a consumer during phase melting of ice by overlay currents is known. -
Однако это устройство оказывает вредное электромагнитное вли ние на канал св зи Ull.However, this device has a harmful electromagnetic effect on the communication channel Ull.
наиболее близким к предлагаемому вл етс устройство дл плавки гололеда без отключени потребител .на воздушных лини х электропередачи, по крайней мере, с трем проводами, содержащее автотрансформатор, вторична обмотка которого ;полкпючена к контуру из двух обогреваемых проводов DlНедостаток такого устройства заклнтчаетс в том, что регулировать ток плавки можно лишь за счет нагрузочного тока линии.The closest to the present invention is a device for melting ice without disconnecting a consumer on overhead power lines with at least three wires, containing an autotransformer, the secondary winding of which is connected to the circuit of two heated wires Dl There is a disadvantage of such a device in It is possible to regulate the melting current only at the expense of the load current of the line.
Цель изобретени - .повы ение эффективности .The purpose of the invention is to increase efficiency.
Указанна цель достигаетс тем, что в устройстве дл плавки гололеда без отключени потребител на воздушных лини х электропередачи, по крайней мере, с трем проводами, содержащем автотрансформатор, вторична обмотка которого подключена к контуру из двух обогревае1 зх проводов, первична обмотка указанного автотрансформатора одним концом подключена к одному из проводов обогреваемого контура , а вторым - к третьему проводу линии.This goal is achieved by the fact that in a device for melting ice without disconnecting a consumer on overhead power lines with at least three wires containing an autotransformer, the secondary winding of which is connected to the contour of two heating wires, the primary winding of the specified autotransformer is connected at one end to one of the wires of the heated circuit, and the second to the third wire of the line.

На фиг. 1 представлена схема устройства дл плавки гололеда ца лини х с изолированной нейтралью на фиг. 2 - то же, на лини х с расщепленной фазой, либо на двухцепных ли5 ни х.FIG. 1 shows a diagram of an apparatus for melting ice lines with an insulated neutral in FIG. 2 - the same, on the lines with a split phase, or on double-circuit lines 5 x.
Устройство дл плавки гололеда содержит провода 1-6 линии электропередачи , сборные шины 7 и 8 подстанций , автотрансформаторы 9 плавкиThe device for melting ice contains wires 1-6 of the power line, busbars 7 and 8 substations, autotransformers 9 melts
0 и перемычки 10.0 and jumpers 10.
Устройство работает следующим образом . ,The device works as follows. ,
При плавке гололеда на линии с изолированной нейтралью .(Фиг. 1)When melting ice on the line with an isolated neutral. (Fig. 1)
5 один из проводов линии, например 1, отключают от сборных шин 7 и 8, собирают контур плавки из Проводов 1 и 2, первичную обмотку автотрансформатора 9 соедин ют с проводами 2 и 3, а вторую обмотку - с проводами 1 и 2. При5 one of the wires of the line, for example 1, is disconnected from busbars 7 and 8, the melting circuit is assembled from Wires 1 and 2, the primary winding of the autotransformer 9 is connected to wires 2 and 3, and the second winding is connected to wires 1 and 2.
