Abstract

The invention discloses a converter valve component, a converter valve and an external insulation test method of the converter valve. The converter valve component is assembled in the converter valveand used for simulating a thyristor in the converter valve, and the converter valve component comprises a first shell, an insulating cushion block and a second shell, wherein the first shell and the second shell are connected to form a closed space; and the insulating cushion block is fixed in the closed space. According to the invention, a silicon wafer of the thyristor is replaced by the insulating cushion block; the converter valve component for simulating the real thyristor in the converter valve is assembled in the converter valve to realize the external insulation test of the converter valve; and the insulation cushion block is non-conductive, so that in the external insulation test process of the converter valve, the thyristor is prevented from being broken down and damaged due to the application of over-high voltage.
