Description

Насто щим изобретением предлагаетс  устрО 1ство дл  обработки металлов электроискровым способом, описанным в основноу авт. сз. № 70010.The present invention proposes a device for treating metals by the electric spark method described in the main author. sz. No. 70010.

Известно, что увеличение мощности дл  установок электроискрового действи  лимитируетс  величине тока в цепи зар да, при Kojopoii возможно по вление дуги между электродами. Дл  устранени  дугообразовани  необходимо одноБременно с увеличением тока короткого заьыкани  увеличивать емкость. Это ведет к хменьшению частоты разр дов контура.It is known that an increase in power for electro-spark installations is limited by the magnitude of the current in the charge circuit, with Kojopoii, the appearance of an arc between the electrodes is possible. To eliminate arcing, it is necessary to increase the capacitance simultaneously with an increase in the short circuit current. This leads to a reduction in the frequency of the contour bits.

В предлагаемом устройстве увеличение мощности установки беч уменьшени  частоты разр дов достигаетс  включением дроссел  с подмагничиванием в цеиь зар да конденсаторов контура.In the proposed device, an increase in the power of the unit to reduce the frequency of the bits is achieved by switching on the throttles with bias in the charge circuit of the circuit capacitors.

Сущность изобретени  по сн етс  прилагаемой схемой.The invention is explained in the attached diagram.

Дроссель 2 насыщени  включен в цепь зар да копденсатора 5. Подмагничивающа  обмотка / расположена на одном сердечнике с дросселем 2. Контур показан жирным шрифтом. Прп размыкании электродов 4 и 5 напр жение на конденсаторе 3 через выпр л итель 6, фильтр 7-8-9 подаетс  на сетку лампы 10 и отпирает ее. При этом обмотка 1 обтекаетс  полным током и создает подмагничивание, вызывающее уменьшение реактивного сопротивлени  обмотки дроссел  2, и, следовательно, возрастание тока зар да. Наоборот, при замыкании электродов 4-5, или при искровом разр де : 1ежду ними, лампа 10 запираетс , снимаетс  подмагничивание и реактанс обмотки дроссел  2 возрастает. Нри этом ограничиваетс  ток проводимости через искровый промежуток и, следовательно, исключаетс  возможность образовани  дуги на электродах.The saturation throttle 2 is included in the charge chain of the capacitor 5. The magnetizing winding / is located on the same core with the throttle 2. The contour is shown in bold. Opening the electrodes 4 and 5, the voltage on the capacitor 3 through the rectifier is 6, the filter 7-8-9 is fed to the grid of the lamp 10 and unlocks it. In this case, the winding 1 is wrapped with a full current and creates a magnetic bias causing a decrease in the reactance of the winding of the choke 2, and, consequently, an increase in the charging current. On the contrary, when the electrodes 4-5 are closed, or when a spark discharge occurs: 1 between them, the lamp 10 is locked, the bias is removed, and the reactance of the windings of the chokes 2 increases. This limits the conduction current through the spark gap and, therefore, eliminates the possibility of arcing on the electrodes.
