Abstract
The invention discloses a ring main unit improvement method for reducing switching station power failure time. The method comprises the following steps of: (1) confirming a specification of a ring main unit needing to be improved in a switching station, and then selecting an appropriate standby ring main unit to be conveyed to the switching station; (2) temporarily interrupting electricity, and disassembling the ring main unit needing to be improved in the switching station; (3) installing the standby ring main unit, and temporarily recovering power; (4) returning and improving the disassembled ring main unit, and after finishing comprehensive debugging, conveying to the switching station; (5) temporarily interrupting electricity, and disassembling the standby ring main unit; and (6) installing the improved ring main unit, and recovering power. Compared with a traditional ring main unit improvement construction scheme, through adopting the improvement method, only few standby ring main units with high generality needs to be provided, and the power only needs to be temporarily cut off when the standby ring main unit is replaced and after the improved ring main unit is replaced, so that the power failure time is greatly reduced; and meanwhile, the whole ring main unit is improved, so that the efficiency for improving the switching station is also greatly improved.
Description
Technical field
The present invention relates to the transformation of ring main unit in the electric power system, be specifically related to a kind of ring main unit remodeling method that shortens the switchyard interruption duration.
Background technology
In traditional ring main unit rebuilding construction scheme, all be that a plurality of ring main units in the switchyard are transformed one by one, impact to residential electricity consumption for avoiding rebuilding construction, usually can only transform 1 ring main unit every day, since 9 power failures in morning, restore electricity before 5.The transformation of ring main unit brings to be interrupted in continuous many days and has a power failure.And the inefficiency of rebuilding construction, the cycle of switchyard rebuilding construction is long.
Summary of the invention
Technical problem to be solved by this invention just provides a kind of ring main unit remodeling method that shortens the switchyard interruption duration, and interruption duration is shortened greatly, reduces the impact on residential electricity consumption, and the efficient of Simultaneous Switching station transformation improves greatly.
For solving the problems of the technologies described above, the present invention adopts following technical scheme: a kind of ring main unit remodeling method that shortens the switchyard interruption duration is characterized in that comprising the steps:
1) then definite ring main unit specification that needs to transform in the switchyard is chosen suitable ring main unit for subsequent use and is transported to switchyard;
2) temporary interruption is removed the ring main unit that needs transformation in the switchyard;
3) ring main unit for subsequent use is installed, is restored electricity temporarily;
4) ring main unit of removing is returned factory and transform, transport switchyard back after comprehensive debugging is complete;
5) temporary interruption is removed ring main unit for subsequent use;
6) improved ring main unit is installed, is restored electricity.
Compare with traditional ring main unit rebuilding construction scheme, adopt remodeling method of the present invention only need be equipped with the high ring main unit for subsequent use of a small amount of versatility, this remodeling method is only being changed ring main unit for subsequent use and is being changed the improved ring main unit stage and cut off the electricity supply temporarily, interruption duration shortens greatly, remodeling method of the present invention is that whole ring main unit is transformed simultaneously, so that the efficient that switchyard is transformed also improves greatly.
Embodiment
A kind of ring main unit remodeling method that shortens the switchyard interruption duration of the present invention comprises the steps:
1) then definite ring main unit specification that needs to transform in the switchyard is chosen suitable ring main unit for subsequent use and is transported to switchyard;
2) temporary interruption is removed the ring main unit that needs transformation in the switchyard;
3) ring main unit for subsequent use is installed, is restored electricity temporarily;
4) ring main unit of removing is returned factory and transform, transport switchyard back after comprehensive debugging is complete;
5) temporary interruption is removed ring main unit for subsequent use;
6) improved ring main unit is installed, is restored electricity.
Above-mentioned steps 2) and the interruption duration that causes of the whole process of step 3) usually be no more than 2 hours; The interruption duration that the whole process of step 5) and step 6) causes is no more than 3 hours usually, that is the time that required power failure is finished in whole ring main unit transformations of removing also be no more than 5 hours, need not will have a power failure the operation in the of twice of ring main unit of transformation as traditional approach.Certainly for the more switchyard of ring main unit, consider interruption duration and actual transformation ability, also can finish by the mode of transforming several times by trying one's best few batch, it also is greatly to shorten the transformation time that such mode is compared with traditional approach.
The present invention is in ring main unit power failure improvement project implementation process, and ring main unit is taked integral hoisting, returned the mode that factory transforms, and after comprehensive debugging is finished, carries out integrative installation technology again, has shortened the field apparatus set-up time, thereby has shortened the interruption duration of power consumer.
Compare with traditional ring main unit rebuilding construction scheme, adopt remodeling method of the present invention only need be equipped with the high ring main unit for subsequent use of a small amount of versatility, ring main unit for subsequent use with switchyard in the ring main unit specification be all mutually most preferably, as long as it also is feasible certainly satisfying other specification ring main unit of the interim power reguirements of switchyard, for example a certain ring main unit is 4 groups in the switchyard, ring main unit for subsequent use can be selected 5 groups or above ring main unit for subsequent use in the situation that the space is feasible.
