Switchgear corresponding in distribution, completes DTU and debugs to the divide-shut brake on the spot of switchgear, treat that the domain leads to
After letter transformation completes to satisfy the requirements, then carry out switchgear stopping labour, complete main website-DTU-switchgear
Remote control joint debugging works, it is seen then that need during whole debugging to stop using as a servant switchgear twice, and in actual work
In work, it is extremely difficult thing that switchgear stops using as a servant, and will shift to an earlier date 2 weeks and arrange to stop labour plan, exists simultaneously
Repeatedly stopping to use as a servant in switchgear grid switching operation repeatedly makes the workload of O&M teams and groups be greatly increased, and stops for twice
The time that labour switchgear spends accounts for about 70 the percent of debugging process, i.e. spends the time longer, enters
And cause work efficiency relatively low.Utilize above-mentioned DTU test gimulator disclosed in the present application, in domain communication
Transform after satisfying the requirements, it is not necessary to stop again to use as a servant switchgear, but directly utilize DTU test gimulator
Complete corresponding debugging efforts, i.e. worked by the remote control joint debugging of main website-DTU-switchgear and change into main website
-DTU-DTU test gimulator remote control joint debugging work, thus decrease switchgear stop use as a servant number of times,
Greatly reduce workload while saving the time, and then improve work efficiency.
