Abstract

The invention discloses a supporting module of a thyristor monitoring and triggering unit of a high-voltage direct current converter valve. The supporting module is of a box structure. The thyristor monitoring and triggering unit is arranged on a radiator of a thyristor. The thyristor is a conductor device with four or more staggered layers P and layers N. A first opening is formed in the area, opposite to an N-type conductor layer, of a P-type conductor layer making contact with the N-type conductor layer, wherein the an N-type conductor layer serves as the cathode. The supporting module is composed of two side panels (2), two or more end boards (1), a bottom board (5) and a board clamping support (7). A slot is formed in the board clamping support (7) which is fixed to the bottom board (5). By the adoption of the supporting module, vibration of the thyristor monitoring and triggering unit of the thyristor is reduced in the working process; an end cover is placed at the upper portion of the supporting module aslant, so that the dustproof and waterproof effects are achieved.

Description

technical field [0001] The invention relates to a high-voltage direct current converter valve device, in particular to a support module of a thyristor monitoring and triggering unit of a high-voltage direct current converter valve. Background technique [0002] The converter valve is the core equipment in the high-voltage direct current transmission system, and the thyristor is the core device of the converter valve. Each thyristor needs to be controlled by an independent trigger system. In order to manufacture high-voltage converter valves, more thyristors need to be used in series. The number of thyristors in a converter station may reach hundreds or even thousands, and the number of monitoring and triggering units is also the same. The current monitoring and triggering units widely use photoelectric triggering and monitoring systems. [0003] Each converter valve tower is composed of several layers of valve modules, and each layer of valve modules contains several or eve...
