Embodiment 1

[0037] The rapid maintenance and replacement of the converter valve power module of the DC distribution network is an important part of the maintenance and repair of the converter valve. This embodiment provides a converter valve power module replacement device, which can realize the rapid replacement of the converter valve power module and improve the The replacement speed and replacement efficiency of power modules are improved, and the safety of power module replacement is improved. Specifically, as figure 1 As shown, the converter valve power module replacement device includes a hoisting module 1 and a refueling module 2. The hoisting module 1 can hoist the refueling module 2 to the installation position of the converter valve power module 101 to be replaced, so that the refueling module 2, the converter valve power module 101 is replaced, which saves the tooling positioning time and improves the replacement efficiency.

[0038]The refueling module 2 includes a support pl...

Embodiment 2

[0060] This embodiment provides a converter valve power module replacement device, which is basically the same as the converter valve power module replacement device provided in the first embodiment. The difference between this embodiment and the first embodiment is that in this embodiment, the suspension The length of the hanger 25 is adjustable. Specifically, the suspension frame 25 is formed by a plurality of hollow telescopic rods that are sleeved together. By sequentially pulling two adjacent telescopic rods, the length of the suspension frame 25 can be extended to adjust the length of the suspension frame 25, which is supported by the suspension member 24, The length of the hypotenuse of the triangle formed by the platform 21 and the valve tower 100 enables the support platform 21 to remain horizontal. Wherein, one of the two adjacent telescopic rods is provided with at least two first engaging portions at intervals along its axial direction, and the other is provided wi...

Abstract

The invention belongs to the technical field of power equipment, and discloses a converter valve power module replacing device which comprises a hoisting module and a material replacing module. Wherein the hoisting module hoists the material changing module to the mounting position of the converter valve power module to be replaced through the hoisting frame, so that the converter valve power module is replaced on the material changing module, the tool positioning time is saved, and the replacement efficiency is improved. The material changing module comprises a supporting platform, and a first connecting piece is arranged at one end of the supporting platform. After the material changing module is hoisted to the installation position, the first connecting piece can be connected with the installation position of the converter valve power module to be replaced, so that the supporting platform is flush with the installation position, the converter valve power module to be replaced can slide to the supporting platform from the installation position, and then the converter valve power module is replaced on the supporting platform. According to the converter valve power module replacing device, the problems that a ladder truck is overweight and a tool is dismounted repeatedly are effectively solved, and the safety and convenience of overhauling are greatly improved.

Description

technical field [0001] The invention relates to the technical field of electric power equipment, and in particular, to a device for replacing a power module of a converter valve. Background technique [0002] At present, in the operation process of the flexible DC distribution network project, the converter valve is the core part of the entire flexible DC distribution network system, which plays a key role in connecting the AC system and the DC system in function, and realizes the mutual conversion of AC and DC energy. Its good operation ability is the most fundamental guarantee for the energy transmission of the whole system. Once there is an abnormal converter valve power module, it needs to be replaced in time. Therefore, the rapid maintenance and replacement of the converter valve power module of the DC distribution network is an important part of the maintenance and repair of the converter valve. [0003] At present, there are generally two ways to replace the power mo...
