Embodiment Construction
[0034] Embodiments of the present invention will be further described below in conjunction with the accompanying drawings.
[0035] A specific embodiment of the crimping type power module valve section of the present invention, such as Figure 1 to Figure 4 As shown, a crimping type power module valve section includes a valve section frame 400 and a plurality of power modules clamped on the valve section frame. The valve section frame includes a left end plate 2 and a right end plate 3, and the two end plates are respectively It has a pressing part for press-fitting with the power module, and two through holes distributed along the front and rear directions at intervals on the two end plates to match the corresponding ends of the front insulation pull rod and the rear insulation pull rod are respectively installed. One is a curved pressure-bearing end plate, and a force balance indicating piece is fixed on the curved surface pressure-bearing end plate to indicate that the end ...

The invention provides a crimping type power module valve segment and a valve segment frame. The crimping type power module valve segment comprises the valve segment frame and a plurality of power modules which are arranged on the valve segment frame in a compressed and clamped manner, wherein the valve segment frame comprises a left end plate and a right end plate, the two end plates are each provided with a top pressing part in top pressing fit with the power modules, through holes distributed at intervals along the fore-and-aft direction are formed in the two end plates, the through holes are used for mounting corresponding ends of front insulating pull rods and rear insulating pull rods in a cooperative manner, the two ends plates are fixed together by means of the front insulating pull rods and the rear insulating pull rods which extend along the fore-and-aft direction, one of the two end plates is a curve-surface pressure-bearing end plate, and a stress balance indicator which isused for indicating that the end plate is balanced under acting forces of the front and rear insulating pull rods is fixedly arranged on the curve-surface pressure-bearing end plate. The crimping type power module valve segment utilizes the stress balance indicator to observe a flat-straight state of the upper curve surface of the curve-surface pressure-bearing end plate, ensures that two end surfaces of the valve segment are completely parallel and are perpendicular to an axial direction of the insulating pull rods, and avoids the overall inclination of the valve segment.
Description
technical field [0001] The invention relates to the technical field of flexible direct current transmission, in particular to a pressure-connected power module valve section and a valve section frame. Background technique [0002] Flexible DC transmission technology is a new type of DC transmission technology based on voltage source converters, turn-off devices and pulse width modulation technology. Due to the advantages of controllability, flexibility and stability, flexible DC transmission technology has broad prospects in distributed power generation, isolated islands and urban expansion power supply. It is the development direction of long-distance and large-capacity DC transmission in the future. Converter valves and valve control equipment are the core technologies. [0003] At present, the power module device is widely used in the field of flexible direct current transmission technology as the core of the power unit of the converter valve. The traditional crimping t...
