Description
Technical Field
The utility model relates to the field of power supply, in particular to a fixed grounding device for a 10kV transformer station.
Background
The safety technical measures of power failure, electricity testing, grounding wire installation and the like are adopted when the safety device works on a distribution line and distribution equipment. The installation of the grounding wire is an important safety measure and is a necessary guarantee for ensuring the personal safety.
The existing 10kV old transformer platform does not have such safety guarantee measures and does not reliably install the position of the grounding wire. When the transformer is in power failure maintenance work, in order to prevent the situations of reverse power transmission and the like caused by aging of the falling porcelain bushing, the grounding wire is hung on the terminal below the falling fuse, and the grounding wire is hung on the primary sleeve of the transformer, so that the randomness of maintenance personnel in the process of installing the grounding wire is large, and the failure rate of equipment is increased. And the shape of the wiring terminal at the lower end of the drop-out fuse is not matched with the ground wire clip, so that the contact area is not enough, the body of the drop-out fuse is easy to damage, and great potential safety hazard is brought to maintainers.
Disclosure of Invention
The utility model aims to solve the technical problem of providing a fixed grounding device for a 10kV transformer station, and solves the problem of safe maintenance of the existing 10kV transformer station without a grounding device.
In order to achieve the purpose, the utility model adopts the following technical scheme:
the fixed earthing device of 10kV transformer platform, fixed earthing device fixed connection is on the rack of 10kV transformer platform, including cross arm, ground connection subassembly on the cross arm, ground connection subassembly's quantity is the same with the quantity of 10kV drop out fuse, ground connection subassembly includes 10kV post insulator, the wiring board, 10kV ground connection link is connected to 10kV post insulator's lower extreme, fastening wiring board between 10kV post insulator and the 10kV ground connection link, the one end of wiring board and the lower extreme pin connection of the 10kV drop out fuse that corresponds, the other end and 10kV transformer's high voltage pin connection.
The wiring board is an aluminum plate.
The wiring board is connected with a lower end lead of the 10kV drop-out fuse through a soft copper wire, copper tinning terminals are arranged at two ends of the soft copper wire, and an insulating layer is arranged on the surface of the soft copper wire.
Compared with the prior art, the utility model has the beneficial effects that:
the transformer rack does not change the structure of the original transformer rack, and has the advantages of simple manufacture, low cost, easy operation, beautiful appearance, direct white appearance, convenient and simple electricity test and grounding wire installation. When the 10kV transformer station is overhauled, the time for arranging safety technical measures during line power failure is shortened, the 10kV side is reliably grounded, the safety measures are standardized, and the safety guarantee of operating personnel is effectively improved.
