¡á ¿µ ¹® ¸Å ´º ¾ó ¡á ¡¡ The thyristor test set YSP 50-01 may be used for the testing of thyristors or diodes. The components may be tested separately, on delivery, for example, or when installed. The following parameters may be testded: - Peak off-state voltage, UDRM up to 5 KV - Peak reverse voltage URAM up to 5 KV - Gate voltage and gate current Ua , Ia The thyristor test set is enclosed in a sheet metal box with a hinged lid for the protection of instruments and controls. The thyristor or diode to be tested is connected to the unit with two high tension cables labelled anode and cathode respectively. The cables are equipped with crooooile type clips for simple and safe contact when the component is mounted in a heat sink. The thyristor test set YSP50-01 is delivered with instructions for correct use of the unit. Supply voltage 220 V/50 Hz or 110 V/60 Hz Test voltages Off-state and reverse voltage tests are performed with half wave rectified a.c. voltage over the test object to avoid heat damage th the semiconductor unit. Off-state voltage and off-state current and reverse, voltage and reverse current respectively are measured at peak value which is read directly from the instruments. Triggering data is measured with a 6 V square wave(50 Hz) as the main voltage between anode and cathode. A d.c. voltage which can be adjusted between O V and 5 V is used as trigger voltage. Safety precautions The high tension unit is completely insulated from earth(10kV). Current is conducted only between the cable connected points labelled anoth - cathode. All test points stand up to earthing. The pushbutton 'Test must be depressed for the duration of the test. Voltage tests always begin from 0 V. If the pushbutton is released during a test, the voltage returns to 0 V and the test must be restarted. The test current is limited to 30 mA or 50 mA. The apparatus enclosure is earthed via the mains voltage cable. If considered necessary the apparatus enclosure can be earthed via a special earthing contact. For larger components of types YST35, YSD35, YST45 and for high voltage components (U>4000 V), YSP50-01 can be used to determine if the voltage characteristic is normal. It is not certain however that UDRM and URAM are reached because of limitations in the leakage current for YSP50-01. Accassories Fixture (YSP 40-02) for presspack thyristor without heat sink. |
