(54) УСТРОЙСТВО ДЛЯ ИЗМЕРЕНИЯ СВАРОЧНОГО ТОКА(54) DEVICE FOR MEASURING WELDING CURRENT
1one
Изобретение относитс к устройствам иэмереми сварочного тока на машинах контакной сварки, примен емых дг монтажа электронных приборов, и может быть испопьзов .но дл измерени сварочного тока на других типах контактных машин.The invention relates to devices having a welding current on contact welding machines, used for mounting electronic devices, and can be used to measure welding current on other types of contact machines.
Известны устройства дл измерени свс.рочного тока, содержшлие трансформатор тока, обмотка которого через детектор под- : ключена к конденсатору и вольтметру.Devices for measuring current current are known, containing a current transformer, the winding of which is connected to a capacitor and a voltmeter through a detector.
Однако необходимость ручного сброса показаний после каждого измерени повышает утомл емость оператора и снижает производительность труда.However, the need to manually reset the readings after each measurement increases operator fatigue and reduces labor productivity.
Цель изобретени - упрощение процесса измерени . Достигаетс это тем, что устройство содержит магнитоуправлкемый контакт и реле времени, причем магнитоуправл емый KOHT8JCT помешен в магнитном поле трансформатора тока и подключен к входу реле времени, выход которого подключен параллельно входу вольтметра.The purpose of the invention is to simplify the measurement process. This is achieved by the fact that the device contains a magnetically controlled contact and a time relay, the magnetically controlled KOHT8JCT located in the magnetic field of the current transformer and connected to the input of a time relay, the output of which is connected in parallel to the input of the voltmeter.
На чертеже дана схема устройства.The drawing is a diagram of the device.
Устройство состоит из трансформатора тока 1, на котором расположен магнитоуправл емый контакт 2, закрепленный пружиной 3. Выход трансформатора тока через детектор 4 включен параллельно запоминак шей емкости 5, замыкающему контакту 6 элемента времени 7 и ламповому вольтмет ру 8. Магнитоуправл емый контакт 2 вс входную цепь элемента времени 7,The device consists of a current transformer 1, on which there is a magnetically controlled contact 2 fixed by a spring 3. The output of the current transformer through detector 4 is connected in parallel with the memory of capacitance 5, the closing contact 6 of time element 7 and the lamp voltmeter 8. Magnetic-controlled contact 2 is all input time element chain 7,
Прибор работает следующим образом.The device works as follows.
Трансформатор тока 1 надеваетс на токопровод шую шину сварочной пепи. В момент прохождени тока по сварочной цепи на выходе трансформатора тока по вл етс напр жение, пропорциональное сварочному току, которое запоминаетс емкостью 5 и измер етс ламповым вольтметром 8. Под действием магнитного пол , создаваемого сварочным током, сргбатывает магнитоуправл емый контакт 2 и включает элемент вре- мани 7, который, отсчитав заданное врем , за;мьпсаёт свой контакт 6. При этом автоматически происходит разр д емкости 5 и сброс показаний прибора.The current transformer 1 is put on the conductor bus bar of the welding peps. At the moment current passes through the welding circuit, a voltage proportional to the welding current appears at the output of the current transformer, which is memorized by capacitor 5 and measured by a lamp voltmeter 8. Under the action of a magnetic field created by the welding current, the magnetic contact 2 is activated and turns on - Mani 7, which, after counting a predetermined time, takes its contact 6. It automatically discharges the capacitance 5 and resets the instrument readings.
