Abstract
The utility model discloses a 10kV armoured switch plum-blossom-type moving contact ground wire. The plum-blossom-type moving contact ground wire comprises a large circular ring cylinder body and a small circular ring cylinder body. The large circular ring cylinder body and the small circular ring cylinder body are fixed and connected together through 8 support ribs. The diameters and the heights of the large circular ring cylinder body and the small circular ring cylinder body are matched with diameters and heights of a bus-bar fixed contact respectively. When bus stopping operation is carried out, a main input switch of the power failure bus section is turned off. After no power is identified, the plum-blossom-type moving contact ground wire is pushed into a 10kV armoured switch mechanism, the plum-blossom-type moving contact and the bus-bar fixed contact are locked automatically. After the power failure bus is discharged fully, the grounding requirement is met, the next overhaul and maintenance work is started, and certain safety guarantee is provided for the overhaul and maintenance work.
Description
technical field
The utility model relates to a kind of earthing device, particularly relates to a kind of 10kV armored switch blossom type moving contact earth connection, is applicable to the bus bar of 10kV armored switching on/off handcart.
background technology
Along with economic develop rapidly, China's power equipment also grows with each passing hour, and 10kV armored switching on/off handcart becomes the main flow equipment of transformer station's low-pressure line-outgoing gradually.But follow the update of equipment, and design concept and practice contradiction increase gradually, and on-the-spot existence conditions can not fully meet need of work, and to operating maintenance, work causes great potential safety hazard.Power transformation operation person on duty is in the work that stops bus at present, 10kV armored switch work peace does not have safe and reliable earth connection while arranging, cannot meet normal service work and safety measure, the condition of equipment self and actual O&M situation have had a strong impact on the switch operation safety of person on duty, and cause certain inconvenience to normal service work.
utility model content
Technical problem to be solved in the utility model is: a kind of 10kV armored switch blossom type moving contact earth connection is provided, stops making 10kV armored switch bus row carry out reliable ground connection in the operating process of bus, provide certain safety guarantee to service work.
The technical scheme that the utility model is taked for technical solution problem is:
A kind of 10kV armored switch blossom type moving contact earth connection, comprises large circle cylindrical shell and small circle ring cylindrical shell, between described large circle cylindrical shell and small circle ring cylindrical shell, is fixed together by 8 brace rods.
The diameter of described large circle cylindrical shell and small circle ring cylindrical shell, highly respectively with the diameter of bus bar fixed contact, highly match each other.
The utility model can directly be placed in inspection trolley top, in the time stopping the operation of bus, power failure bus section, busbar section master enters switch and disconnects, identify without after electricity, the utility model is pushed into 10kV armored switching mechanism inside, make blossom type moving contact and bus bar fixed contact automatically stuck, after power failure bus fully discharges, complete grounding requirement, start to carry out next step repair and maintenance work, for repair and maintenance work provides certain safety guarantee.
The utility model meets the earth connection standard of defined in " electrical safety working regulation ", ground wire journey blossom type, and conforming to 10kV armored switching on/off handcart bus bar fixed contact can be automatically stuck, guarantees that contact is good.
accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the end view of Fig. 1;
Fig. 3 is use state reference map of the present utility model.
embodiment
Below in conjunction with accompanying drawing, the utility model is further described:
Referring to Fig. 1, Fig. 2 and Fig. 3, a kind of 10kV armored switch blossom type moving contact earth connection, comprise large circle cylindrical shell 1 and small circle ring cylindrical shell 2, between large circle cylindrical shell 1 and small circle ring cylindrical shell 2, be fixed together the diameter of large circle cylindrical shell 1 and small circle ring cylindrical shell 2, highly respectively with the diameter of bus bar fixed contact, highly match each other by 8 brace rods 3.
In the time stopping the operation of bus, power failure bus section, busbar section master enters switch and disconnects, identify without after electricity, the utility model is pushed into 10kV armored switching mechanism inside, make blossom type moving contact and bus bar fixed contact automatically stuck, after power failure bus fully discharges, complete grounding requirement, start to carry out next step repair and maintenance work, for repair and maintenance work provides certain safety guarantee.
