Description
Technical field
The present invention relates to buckling cabinet fields, more specifically to a kind of shunt nodes type PT cabinet.
Background technique
For urban power distribution network largely using putting cable underground, solving urban aerial line influences beauty, tree line contradiction, building line at present
The problems such as contradiction etc..But new problem has also been bred simultaneously, i.e. cable run distance to the ground is close, so almost arriving using all insulation
The route at bottom designs, once breaking down or overhauling, can not carry out operation using livewire work mode, can only have a power failure and be made
Industry, and power off time is also very long.In traditional ring network cabinet or switching station, a standby spacing can be generally reserved, at certain
When line failure need to overhaul, powered using standby spacing to the load under this route.But it is quick due to city load
Increase and urban land is more and more nervous, there is no standby spacings in ring network cabinet and switching station in many cases, therefore work as
When line failure need to overhaul, it is necessary to have a power failure, this reduces power supply reliabilities.
The scheduled outage time of China's distribution at present accounts for relatively high (about 71.70%), and uninterrupted operation technology is in operation
There is also gaps compared with developed countries for method and project, operating personnel, power tool and equipment aspect.According to country
" QGDW/10520-2016 10kV distribution uninterrupted operation specification ", distribution upkeep operation should follow the principle of " energy band is not stopped ".
In view of the above problems, referring to the experience of external developed regions, national grid proposes the concept of first telegram in reply, rear operation.
Grid structure is improved first, by the way that bulk power grid is divided into several minor scale power nets, by the way of more segmentations, interconnecting more, auxiliary intelligence
Change electric power network technique and reaches uninterrupted operation.Secondly pressure electric car, case become vehicle in using, the operating equipments such as bypass cable carry out face or
The first telegram in reply operation of point reduces and has a power failure, and improves power supply reliability.But in practical applications, still following problems can not solve:
1, cable duct catches fire: in Chinese most cities, urban power consumption growth is much unable to catch up in cable duct design
Speed, so cable duct is constantly in state disorderly and unsystematic, crowded, more than hidden danger point, often major loop, back-up circuit, branch
Circuit is all in a bar ditch, once kindling, rack interconnection is directly disconnected.
2, switchgear house inlet wire failure: in Chinese most cities, it can not also accomplish that all switchgear houses have multiloop
Inlet wire, for single loop inlet wire, once power supply lacks, user can only have a power failure.
3, it capacity problem: carries out turning electricity band confession by grid structure, if regular link capacity is inadequate, can not meet failure
Uninterrupted operation purpose still cannot be achieved in line user capacity requirement.
4, temporary electricity: occasion encounters guarantor's electricity, not interim enough the increase-volume of capacity, needs to take electricity from existing rack or move
Dynamic plant-grid connection.
Problem above can not all be solved the short time by grid structure optimization.At present use in pressure electric car, case become vehicle,
The operating equipments such as bypass cable carry out the first telegram in reply operation of face or point.From technical know-how level it is that there is no problem, but in practical work
In work, these operating equipments seldom can find not have a power failure in cable system route and quickly access a little.
