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.

Description

technical field [0001] The invention relates to the field of insulation tests for converter valves, in particular to a converter valve component, a converter valve and an external insulation test method for the converter valve. Background technique [0002] This section is intended to provide a background or context to embodiments of the invention that are recited in the claims. The descriptions herein are not admitted to be prior art by inclusion in this section. [0003] With the development of UHV DC transmission technology, the voltage level and transmission capacity of DC transmission continue to rise, and the technical level of converter valves develops by leaps and bounds. The complexity of its application methods and application environments puts forward higher requirements for its performance. It is very important for the stable operation of the converter valve to verify the performance of the converter valve by various tests (for example, the test for verifying th...
