The present invention by means of bypass cable branch case, enable the corresponding power line of switching cabinet and put for electric line temporarily, and obtain the power-on time at interval, substantially reduce the power off time of user, owing to have employed segmentation transformation, make transformation more orderly and simple, it is possible to effectively to shorten the transformation duration, and have a power failure in short-term several times, customer power supply is not affected when transforming basis and more renew bus looped network cabinet, facilitate user, there is good practicality, also substantially increase power supply reliability.
Description
Technical field
The present invention relates to the transformation of a kind of switching cabinet and replacing options, particularly a kind of method changing switching cabinet based on the case segmentation transformation of bypass cable branch.
Background technology
Along with the development of economy, the 10kV switching station that builds up in early days, opening and closing institute, distribution substation time of putting into operation is long, and the operating equipment models such as switching cabinet are old and seriously aging, can not meet the demand that load is growing, and failure rate height, and customer complaint is many, are badly in need of transformation. When switching station being carried out overall transformation, it is necessary to power failure operation, long in time limit owing to transforming, cause power off time long, not only bring great inconvenience to user, also have impact on the reliability of power supply.
Summary of the invention
It is an object of the invention to provide a kind of according to the deficiencies in the prior art part and realize not having a power failure or having a power failure in short-term transformation switching station, shorten customer outage hours, shorten the transformation duration, it is to increase the method changing switching cabinet based on the case segmentation transformation of bypass cable branch of power supply reliability.
It is an object of the invention to be realized by following approach:
Change the method for switching cabinet based on the case segmentation transformation of bypass cable branch, its main points are, comprise following sequential steps:
1, a kind of bypass cable branch case is provided, comprises casing and be positioned at the channel-section steel below casing, a plurality of cable connection terminal being provided with three-phase bus bar copper row in casing and being positioned on this three-phase bus bar copper row;
2, being installed in the scene of switching cabinet to be replaced by above-mentioned bypass cable branch case, described switching cabinet to be replaced includes I section bus-tie circuit breaker cabinet and II section bus-tie circuit breaker cabinet;
3, the first stage has a power failure in short-term, the different cable that outlet cable by the incoming power cable of I section bus-tie circuit breaker cabinet with to single power supply user is connected in bypass cable branch case via the channel-section steel below casing respectively connects on terminal, having a power failure to the outlet cable of two power supply user in I section bus-tie circuit breaker cabinet, two power supply user provides inlet wire to power separately;
4, remove I section bus-tie circuit breaker cabinet, and this cabinet basis is transformed, and install new I section bus looped network cabinet;
5, subordinate phase has a power failure in short-term, according to the electric hookup of I section bus looped network cabinet, all for I section bus-tie circuit breaker cabinet turnover line cables is carried out overlap joint and installs;
6, repeating step 3-5 changes II section bus-tie circuit breaker cabinet, and transformation replacing removes bypass cable branch case after terminating.
Like this, the present invention by means of bypass cable branch case, enable the corresponding power line of switching cabinet and put for electric line temporarily, and obtain the power-on time at interval, substantially reduce the power off time of user, owing to have employed segmentation transformation, make transformation more orderly and simple, can effectively shorten the transformation duration, and have a power failure in short-term several times, do not affect customer power supply when transforming basis and more renew bus looped network cabinet, facilitate user, there is good practicality, also substantially increase power supply reliability.
Accompanying drawing explanation
Fig. 1 show the structural representation of bypass cable branch of the present invention case;
Below in conjunction with embodiment, the present invention is described further.
Specific embodiment
Most preferred embodiment:
For I section bus-tie circuit breaker cabinet, change the method for switching cabinet based on the case segmentation transformation of bypass cable branch, comprise following sequential steps:
1, whether site inspection 10kV to be rebuilt switching station has enough spaces can put bypass cable branch case.
2, site inspection 10kV inlet wire, feed out cable and whether leave enough nargin and can return cable to sob and be connected to bypass cable branch case.
3, a kind of bypass cable branch case is provided, comprise casing 1 and it is positioned at the channel-section steel 2 below casing, the a plurality of cable connection terminal 4 being provided with three-phase bus bar copper row 3 in casing 1 and be positioned on this three-phase bus bar copper row, the height of channel-section steel 2 must ensure the bending radius of cable.
4, above-mentioned bypass cable branch case is installed in the scene of I section bus-tie circuit breaker cabinet, and start the first stage and have a power failure in short-term, the different cable that outlet cable by the incoming power cable of I section bus-tie circuit breaker cabinet with to single power supply user is connected in bypass cable branch case via the channel-section steel below casing respectively connects on terminal, and confirm that bypath system is consistent with original system phase sequence, having a power failure to the outlet cable of two power supply user in I section bus-tie circuit breaker cabinet, two power supply user provides inlet wire to power separately.
5, incoming power offside circuit is turned maintenance by running, power to bypass cable branch case, feeder line offside circuit is turned maintenance by running, bypath system is put into operation, recover offside user power utilization.
6, remove I section bus-tie circuit breaker cabinet, and this cabinet basis is transformed, and install new I section bus looped network cabinet.
7, subordinate phase has a power failure in short-term, according to the electric hookup of I section bus looped network cabinet, all for I section bus-tie circuit breaker cabinet turnover line cables is carried out overlap joint and installs.
It is same as the prior art that the present invention does not state part.
