Description
(54) УСГЮЙСГВО ДЛЯ ГСЛЕЙНОЙ ЗАЩИТЫ ОТ ПОВРЕЖДЕНИЯ УЧАСТКА СЕТИ АВТОНОМНОЙ ЭЛЕКТЮЭНЕРГЕТИЧЕСКОЙ СИСТЕМЫ(54) USGUSGVO FOR GLOSSY PROTECTION AGAINST DAMAGE TO THE SECTION OF THE NETWORK OF AUTONOMOUS ELECTRIC POWER SYSTEM
7 и выходной орган 8, блок питани защиты доШШ нен блоком 9 аварийного отключени .7 and the output unit 8, the power supply unit of the protection of the secondary level of the emergency shutdown unit 9.
Устрс йство работает следующим образом.The facility operates as follows.
В нормальном режиме на входе выходного органа 8 присутствует напр жение от блока 6 питани , которое блокирует срабатьшание выходного органа. При коротком замыкании на защищаемом участке 1 сети выходной сигнал датчика 4 посредством кабел 2 подаетс на вход реагирзтощего органа 3, который воздействует на блок 9 аварийного отключени . Блок 9 аварийного отключени отключает блок 6 питани и на входе выходного органа 8 исчезает блокирующее напр жение, выходной орган, воздейству на коммутирзаощий блок 7, отключает поврежденный участок сета. In the normal mode, at the input of the output organ 8 there is a voltage from the power supply unit 6, which blocks the output of the output organ. In the event of a short circuit in the protected area 1 of the network, the output signal of the sensor 4 through the cable 2 is fed to the input of the reacting authority 3, which acts on the emergency shutdown unit 9. The emergency shutdown unit 9 shuts down the power supply unit 6 and the blocking voltage disappears at the input of the output organ 8, the output organ, acts on the switching unit 7, turns off the damaged portion of the set.
Наличие в устройстве блока 9 авари| ного отключени позвол ет, вы влйть также возрастание тока, потребл емого защитой от блока 6 питани и отключать последний при неисправйосг х в защите , предотвраща тем самым работу участка сети при поврежденной защите. Кроме того, любые повреждени (обрывы и.короткие замыкани ) во входной цепи выходного органа 8 (т.е. в кабеле 5, соединении между датчиком 4 и выходным ор . ганом 8) или потер питани защитой привод т к отключению защищаемого участка сети.The presence in the device unit 9 crash | A disconnection also allows you to take an increase in the current consumed by the protection from the power supply unit 6 and to disconnect the latter when there is a fault in the protection, thereby preventing the network section from operating when the protection has been damaged. In addition, any damages (breaks and short circuits) in the input circuit of the output unit 8 (i.e., cable 5, connection between sensor 4 and output power circuit 8) or loss of power by the protection trips the protected network section.
Таким образом, устройство имеет распшре ные функциональные возможности и уменьшенноеThus, the device has widespread functionality and reduced
число кабелей, что повыщает его надежность и упроща;ет монтаж на объекте.the number of cables, which increases its reliability and simplicity; there is installation on site.
