Between the electrode and the cathode of the SCR control is a PN junction thyristor BTA212, so it forward resistance around Europe in a few - a few hundred ohms scale, reverse resistance is larger than the forward resistance. But handling extremely diode characteristics are less ambitious, the reverse was not completely blocked condition, you can have a relatively large current through, thus SCR BTA312, sometimes measured handling extremely negative resistance is relatively small, and does not clarify the manipulation very characteristic is not good. In addition, in a very positive and negative control when measuring the resistance, the multimeter should be placed on R * 10 or R * 1 block, to avoid manipulation of extremely high reverse breakdown voltage. If the measured positive and negative elements of yin and yang is very short or very short-circuiting the anode and the manipulation or control electrode and cathode reverse short-circuit or open circuit thyristor control electrode and cathode clarify elements are damaged. SCR sub-way SCR and triac are two, all three electrodes. Way thyristor cathode (K), the anode (A), control pole (G). Equivalent to two single triac thyristor reverse parallel connection. During a way that the silicon anode and cathode of the other side of the company, said its terminals T2 pole, during a unidirectional silicon cathode and anode connected to the other, said its terminals T2 pole, was handling the remaining pole (G). SCR thyristors (SCR): industrial and agricultural production in China and is mainly used in civilian areas: communication regulator, controlled rectifier and non-contact power static switches and other areas. Communication regulator is using thyristor (SCR) to replace the old switching characteristic touch regulator, induction regulator and the reactor pressure regulator with a thyristor (SCR) to complete the communication to transform communication between variable called Communication regulator. It is mainly used for temperature control SCR BTA208, lights, and communication control motor speed regulator and other areas. With thyristor controlled rectifier (SCR) rectifier consisting of voltage can communicate in the same circumstances, to facilitate changes in the size of the DC output voltage can be controlled rectifier. Thyristor controlled rectifier SCR has replaced the DC generator for DC drive speed equipment, widely used in steel rolling, electrolysis, electroplating, machine tools, paper, textiles, and other areas of the field.
