Abstract
PURPOSE: To facilitate the measurement for the off-gate current of the gate turn-off thyristor by inserting the shunt possessing the measurement piece in series into the gate transformer.
CONSTITUTION: Transistor 3 is connected to control power bus bar 1 to generate the off-gate current, and capacitor 5 is provided at the primary side of gate transformer 4. And thyristor 6 is provided at the secondary side of transformer 4 along with shunt 7 connected to the anode side each. Shunt 7 consists of current piece 7a and measurement piece 7b. Piece 7a sets the current flowing to piece 7b to about several or several tens ampere by varying the diameter, length and material of the line. And piece 7b uses the Hall device or the like to secure the measurement via the knob-type current detector. Then the large-capacity gate turn-off thyristor is connected to piece 7b, and thus the off-gate current can be measured in an extremely easy way.
