Abstract

The invention relates to a separated flexible direct current module based on tulip contacts. The separated flexible direct current module comprises a module head, connecting pieces, a capacitor assembly, tulip contact assemblies, a driving mechanism and guiding mechanisms; the module head is arranged at one sides of the tulip contact assemblies, the capacitor assembly is arranged at the other sides of the tulip contact assemblies, one side of the capacitor assembly is provided with the connecting pieces, one side of the module head is provided with the guiding mechanisms, and the bottom end of the module head is provided with the driving mechanism. According to the device, the module head and the capacitor are separated by the tulip contacts, and therefore the overhauling efficiency of the flexible direct current module can be more efficiently improved; separated transportation of the module head and the capacitor can be achieved, the condition that a laminated busbar pulls an IGBT due to shaking of the capacitor in the transportation process can be effectively avoided, and then the risk that the IGBT is pulled to be damaged is reduced; the insertion and extraction process of the module head and the capacitor is easily achieved by adopting the driving mechanism. The separated flexible direct current module based on tulip contacts is simple in design and convenient to popularize.

Description

Technical field [0001] The invention relates to the field of flexible direct current transmission, in particular to a separate flexible straight module based on plum blossom contacts. Background technique [0002] With the increasing maturity of my country's DC transmission technology, there are more and more flexible straight products. Among them, the flexible DC converter valve is an important part of the DC transmission system, and its operation directly affects the transmission capacity of the entire system. The flexible straight module is a key component of the flexible DC converter valve. Its capacity ranges from a few MW to the current several thousand MW, and the voltage level can reach ±500kV. The increase in the capacity of the flexible straight module will inevitably lead to a substantial increase in weight. At present, the flexible straight module mostly adopts the integrated solution of module head and capacitor. The flexible straight module is installed on a valv...
