Abstract

FIELD: electronic devices. SUBSTANCE: device has electromagnetic relay 1 and controlled two-sided semiconductor switch 2, which is connected in parallel to relay switch, and control unit 3, which controls relay and semiconductor switch so that when load is connected to power supply, semiconductor switch is turned on at zero voltage level of alternating current. Then after delay relay switch is turned on. When load is disconnected from power supply, relay switch is turned off, then semiconductor switch is turned off at zero voltage level of alternating current. In addition control unit 3 has unit which switches semiconductor switch 2 off when relay switch is turned on when load is connected to power supply and switches semiconductor switch off before relay switch is turned off when load is disconnected from power supply. EFFECT: increased functional capabilities. 1 dwg

Изобретение относится к электронному коммутатору. Электронный коммутатор содержит электромагнитное реле 1 и управляемый двусторонний полупроводниковый переключатель 2, например симистор, соединенный параллельно с выключателем 1b реле, а также блок 3 управления для управления реле и полупроводниковым переключателем так, что при подключении нагрузки к источнику энергии сначала включается полупроводниковый переключатель в нулевой точке напряжения переменного тока, затем после задержки включается выключатель реле, а при отключении нагрузки от источника энергии вначале выключается выключатель реле, а затем после задержки выключается полупроводниковый переключатель в нулевой точке переменного тока. Согласно изобретению блок 3 управления также содержит средство для выключения полупроводникового переключателя 2 после включения выключателя 1b реле при подсоединении нагрузки к источнику энергии и для включения полупроводникового переключателя 2 перед отключением выключателя 1b реле 1 при отключении нагрузки от источника энергии.

The invention relates to an electronic switch. The electronic switch contains an electromagnetic relay 1 and a controlled two-way semiconductor switch 2, for example a triac connected in parallel with the switch 1b of the relay, as well as a control unit 3 for controlling the relay and the semiconductor switch, so that when the load is connected to the power source, the semiconductor switch is first turned on at zero point AC voltage, then after a delay, the relay switch turns on, and when the load is disconnected from the power source, off ents relay, and then after a delay the semiconductor switch is turned off at the zero point of AC current. According to the invention, the control unit 3 also comprises means for turning off the semiconductor switch 2 after turning on the relay switch 1b when the load is connected to the power source and for turning on the semiconductor switch 2 before disconnecting the switch 1b of the relay 1 when the load is disconnected from the power source.
