Description

Изобретение касаетс  устройств зажигани  ртутных выпр мителе .The invention relates to mercury rectifier ignition devices.

Известны устройства дл  зажигани  (возбуждени ) дуги в ртутных выпр мител х, содержащие трансформаторы, вспомогательные полупроводниковые вентили и дроссель возбуждени . Известные устройства дл  отключени  зажигател  после возбуждени  вспомогательной дуги содержат реле и контакторы, собствеЕШое врем  срабатывани  которых достигает нескольких периодов, что и предопредел ет инерционность системы зажигани .Arrangements for ignition (excitation) of an arc in mercury rectifiers are known, which contain transformers, auxiliary semiconductor valves, and an excitation choke. The known devices for switching off the ignitor after the excitation of the auxiliary arc contain relays and contactors whose proper response time reaches several periods, which predetermines the inertia of the ignition system.

Предлагаемое изобретение имеет цель повысить надежность и быстродействие устройств зажигани . Его отличительной особенностью  вл етс  применение дл  коммутировани  цепи зажигани  дроссел  насыщени , работающего в релейном режиме. Рабочие обмотки дроссел  включены в цепь зажигател , а обмотки управлени  - в цепь дуги возбуждени .The present invention aims to improve the reliability and speed of ignition devices. Its distinguishing feature is the application for switching the ignition circuit of the saturation throttle operating in the relay mode. The working windings of the throttles are included in the igniter circuit, and the control windings are connected to the circuit of the excitation arc.

На фиг. 1 и 2 приведены в качестве примера соответствующие электрические схемы дл  случа  применени  полупроводниксвоги зажигател . На фиг. 1 дуга возбуждени  питаетс  по двухполупериодной схеме с нулевым выводом. На фиг. 2 приведена схема дл  однофазного зажигани  - возбуждени , в которой питание одного из анодов возбуждени  происходит за счет энергии, запасаемой в катодном дросселе возбужлени .FIG. Figures 1 and 2 illustrate by way of example the corresponding electrical circuits for the case of using semiconductor ignitors. FIG. 1 excitation arc is powered by a full-wave zero-output circuit. FIG. Figure 2 shows a circuit for single-phase ignition-excitation, in which the power of one of the excitation anodes occurs due to the energy stored in the cathode excitation choke.

bhi чертежах обозначены: РВ - ртутный вынр .итель, 3-полупроводниковый зажигатель, / и 2-аноды возбуждени , 7 -трансформатор зажигани  возбуждени , ff --обмотки зажига1и1Я, Г,- обмотки возбуждени , D - дроссель зажигани , D,, -дроссель возбуждени . В - селеновый выпр митель. Устройство по схеме фиг. 1 работает н следующей последовательности.bhi in the drawings are designated: PB - mercury detector, 3-semiconductor igniter, / and 2 excitation anodes, 7 excitation ignition transformer, ff - ignition windings, Г, - excitation windings, D - ignition choke, D, - throttle excitation. B - selenium rectifier. The device according to the scheme of FIG. 1 works in the following sequence.

При подаче напр жени  на трансформатор цепи зажигател  и обмотке W дросел  D,, протекает пульсирующий ток. Посто нна  составл юща  этого тока насыщает дроссель D. сопротивление его падает , и ток зажигател  резко возрастает. После зажигани  катодногоWhen voltage is applied to the transformer of the ignitor circuit and winding W of the throttle D, a pulsating current flows. The constant component of this current saturates the inductor D. its resistance drops, and the current of the igniter increases sharply. After igniting the cathode
