Description
Устройство содержит каскад 1 коммутации , схему 2 управлени и блок 3 снижени потенциала.The device comprises a switching stage 1, a control circuit 2 and a potential reduction unit 3.
Устройство работает следующим образом .The device works as follows.
При подаче сигнала на включение со схемы 2 управлени на каскад 1 коммутации одновременно подаетс сигнал на блок 3 снижени потенциала.When the signal for switching on is applied from the control circuit 2 to the switching stage 1, a signal is simultaneously supplied to the block 3 for potential reduction.
Бдок 3 снижени потенциала состоит из ниэкоомного сопротивлени 4 с последовательно включенным ключевым элементом 5, например тиристором. При чем, сопротивление подключено к выходу блок„а коммутации, а ключевой элемент - к земле. Ключевой элемент управл етс сигналами, идущими одновременно на вспомогательный вентиль каск-ада коммутации и на ключевой элемент При этом закрываетс основной управл емый вентиль,обесточива защищаемую сеть, а блоком 3 снижени потенциала выход каскада 1 коммутации соедин етс через сопротивление и ключевой элемент на землю. Так как подключаемое The potential reduction bdc 3 consists of an impedance resistance 4 with a key element 5 in series, for example a thyristor. Moreover, the resistance is connected to the output of the “switching unit” and the key element to the ground. The key element is controlled by signals that go simultaneously to the auxiliary gate of the switching cash register and the key element. This closes the main controlled valve, de-energizes the protected network, and the potential reducing unit 3 connects the output of the switching stage 1 through the resistance and the key element to ground. Since the plug
сопротивление в несколько раз меньше сопротивлени человека, потенциал снижаетс до безопасной величины.resistance is several times less than human resistance, the potential is reduced to a safe value.
Таким образом применение предложенного быстродействующего автоматического выключател посто нного тока исключает поражение человека от электрического потенциала, выносимого в сеть при эксплуатации известного устройства , и расшир ет функциональные возможности устройства.Thus, the application of the proposed high-speed DC circuit breaker eliminates the damage to humans from the electric potential carried into the network during operation of the known device, and expands the functionality of the device.
