The utility model comprises the following components: earthing device (1), earthing device's upper end pass through the bolt and decide the last flange joint of cold water pipe (6), earthing device's lower extreme pass through the bolt and decide the lower flange joint of cold water pipe, earthing device include outer panel (3), the outer panel be the bent plate of cell type structure, its inboard upper portion and interior plate (5) laminate in the right angle department, the interior plate be right angle shape bent plate, the interior plate with the outer panel connect and fix through the nut through connecting bolt A (2), connecting bolt B (3) respectively. The grounding device is used for the catchment pipe grounding device of the stator water-cooled generator.
Description
Technical Field
The utility model relates to a water collecting pipe grounding device of a stator water internal cooling generator.
Background
The existing technology is that the generator catchment pipe is connected with the generator base through the copper grounding connection piece, when the catchment pipe grounding connection piece is opened during the electrical high-pressure test of the generator, the fixed cold water pipe and the generator base flange connection bolt need to be disassembled, the mode is more complicated, and the bolts are disassembled and assembled many times, so that the flange joint surface is easy to leak hydrogen, the workload and the working time of personnel are increased, and potential safety hazards are caused to equipment.
Disclosure of Invention
The utility model aims to provide a catchment pipe grounding device of a stator water internal cooling generator, when a catchment pipe grounding connecting sheet needs to be opened in a generator high-pressure test, a fixed cold water pipe and a generator base flange connecting bolt do not need to be dismounted, separation can be realized by directly dismounting 2 bolt assemblies, the operation is simple, and the safe and stable operation of equipment is effectively ensured.
The above purpose is realized by the following technical scheme:
the utility model provides a stator internal water cooling generator catchment pipe earthing device which constitutes and includes: earthing device, earthing device's upper end pass through bolt and the last flange joint of deciding the cold water pipe, earthing device's lower extreme pass through the bolt and decide the lower flange joint of cold water pipe, earthing device include the outer panel, the outer panel be the bent plate of cell type structure, its inboard upper portion and interior plate laminate in the right angle department, the interior plate be right angle shape bent plate, the interior plate with the outer panel connect and fix through the nut through connecting bolt A, connecting bolt B respectively.
The inner side plate and the outer side plate are copper plates with the same thickness and width, the upper plane of the inner side plate is provided with a groove, and the lower plane of the outer side plate is provided with a groove.
Has the advantages that:
1. the utility model relates to a stator water-cooled generator catchment pipe grounding device, which solves the problem that a grounding connecting sheet can be tested only after a fixed cold water pipe and a generator base flange connecting bolt need to be removed when a stator water-cooled generator is subjected to an electrical test during maintenance, overcomes the defect of hydrogen leakage caused by the fact that bolts are removed for multiple times, can realize separation by directly removing the connecting bolt A and the connecting bolt B, does not generate friction welding phenomenon among different materials, is simple and reliable to operate, improves the working efficiency, and ensures the safe operation of equipment.
