Description

Предлагаетс  взрывобезопасный включатель дл  включени  напр жени  в сеть электрического запаливани  электродетонаторов или электровоспламенителей , содержащий реле с неоновой лампой, и прерыватель , выключающий реле после посылки в цепь запаливапи  импульса тока.An intrinsically safe switch is provided to turn on the voltage to the network of electric ignition of electric detonators or electric igniters, which contains a relay with a neon lamp, and an interrupter that turns off the relay after sending a current pulse to the circuit.

Такого рода устройства дл  автоматического включени  напр жени  в запальную цепь с помощью реле, срабатывающего при зажигании неоновой лампы, т. е. максимальной величине напр жени , известны.Such devices for automatically turning on the voltage in the pilot circuit by means of a relay which is triggered when the neon lamp is ignited, i.e., the maximum voltage value is known.

Отличительна  особенность предлагаемого включател  заключаетс  в применении стонорно-фиксирующего размыкател  цепи реле, обесиечивающего выключение запальной ценн после посылки импульса тока.A distinctive feature of the proposed switch is the use of a relay-holding release circuit breaker, which switches off the pilot ignition after sending a current pulse.

Схема описываемого взрывобезонасного включател  сети состоит из следующих элементов: выключател  сети /, обмотки реле 2, железа  кор  5, изол ционной плапки 4, рабочих контактов 5 vi 6, линейных контактов 7, 8, 9 W 10, линейных зажимов // и /2, размыкающих контактов 13 14 стопора 15, фиксатора 16, неоновой лампы 17, балластного сопротивлени  18, трансформатора 19.The scheme of the described explosive-free network switch consists of the following elements: network switch /, relay 2 windings, iron core 5, insulation pad 4, working contacts 5 vi 6, line contacts 7, 8, 9 W 10, linear clamps // and / 2 , the opening contacts 13 14 of the stopper 15, the clamp 16, the neon lamp 17, the ballast resistance 18, the transformer 19.

Вс  аппаратура монтируетс  во взрывобезопасной оболочке.All apparatus is mounted in an explosion-proof enclosure.
