Embodiment Construction

[0039] In order to better understand the present invention, the content of the present invention will be further described below in conjunction with the accompanying drawings and examples.

[0040] The thyristor converter valve module provided by the present invention is as figure 1 As shown: the valve module is in the shape of "concave", including the combination frame 1, the thyristor pressing mechanism 2 installed in the combination frame 1, the damping capacitor 4, the saturated reactor 7, the gate box 3 and the water cooling system, and the combination Shielding cover 8 on the periphery of the frame.

[0041] like figure 2As shown, the combined frame 1 is used as the bearing matrix of all components in the valve module, and is composed of several metal beams 12, non-metallic insulating beams, cross-brace insulators 9 and related link accessories, which can not only ensure the structural strength of the valve module, but also meet the Valve module high voltage insulatio...

Abstract

The invention provides a thyristor converter valve module, the valve module includes a combination frame, a thyristor pressing mechanism installed on the combination frame, a damping capacitor, a saturated reactor, a gate box and a water cooling system, and a Peripheral shielding cover; the combined frame is convex and includes a first rectangular frame and a second rectangular frame and a third rectangular frame symmetrically arranged at the two outer ends on the same side of the first rectangular frame. The structure arrangement of the valve module provided by the present invention is more stable and reasonable, light in weight and strong in load-bearing capacity, and satisfies the insulation requirements inside the valve module and the shielding effect outside the valve module while ensuring the structural strength of the valve module.

Description

technical field [0001] The invention relates to a valve module, in particular to a thyristor converter valve module, which belongs to the field of high-voltage direct current transmission. Background technique [0002] The core component of the converter valve is the thyristor, whose voltage level is thousands of volts, and the voltage level of the power grid is much higher than the voltage level of the thyristor. In order to realize the commutation, a low-voltage, low-power basic The converter valve module, through the horizontal and vertical expansion of the converter valve module, realizes the mutual communication of multiple modules to meet the needs of high-voltage and high-power power transmission occasions. [0003] At present, the converter valve modules are all designed with a rectangular shape. The thyristor press-fitting mechanism in the valve module is arranged in a straight line, and other devices are arranged on both sides of the thyristor press-fitting mechani...
