Description

There is the common case enclosed busbar of maintenance function
Technical field
The utility model relates to common case enclosed busbar maintenance field, is specifically related to the common case enclosed busbar with maintenance function.
Background technology
Enclosed busbar comprises isolated-phase enclosed bus and common case (containing case altogether every phase) enclosed busbar, is widely used in the lead-in wire of power plant, electric substation, industry and civilian power supply.Isolated-phase enclosed bus is a kind of big current transmitting device being widely used in 50MW and above generator lead-out wire loop and house branch bus loop.
And for power plant, general employing is total to case enclosed busbar.Altogether case enclosed busbar comprise not every mutually altogether case enclosed busbar every mutually altogether case enclosed busbar and alternating current-direct current excitation altogether case enclosed busbar be widely used between below 100MW generator lead-out wire and main transformer low-pressure side or 75MW and the current delivery between above unit auxiliary transformer low-pressure side and high voltage distribution installation altogether case enclosed busbar also can be used for generator alternating current-direct current energized circuit, the power supply lead wire of bus or other industrial civilian installation is introduced in the electricity consumption of institute of electric substation.
Case enclosed busbar conductor adopts copper aluminium bus array or the compact fortune easy for installation of groove aluminium groove steel structure altogether.Row maintenance workload is little, and degree of protection is the earth fault that IP54 substantially can eliminate extraneous moisture dust and foreign object and causes.Shell adopts aluminium sheet to make, antiseptic property is good, and the extraneous turbulence loss avoided caused by steel shell, shell is electrically gone up and is all communicated with and multipoint earthing, stop personal Danger Electric shock risk and do not need to arrange wire net to simplify to need on busbar, to overlap heat-shrinkable T bush according to user to the requirement of civil engineering and at mounting heater and respirator etc. in casing with the scope of application of reinforced insulation phase-splitting enclosed busbar in big power station be: from generator outlet terminal, to the major loop bus of main transformer low-pressure side leading-out terminal, bus of independently asking the way leads to station service transformer and voltage transformer, each branch line of the equipment cabinets such as lightning arrester.In actual use, need to be provided with opening at cab signal box top, so that the inspection in installation and later stage.But although the housing antiseptic property of aluminum design is better, but its poorly sealed reality, so out of doors under condition, having the rainwater of part, dust or impurity enters in cab signal box by gap, of long duration porcelain vase surface can be made dirty, near porcelain vase, moisture is heavier, and flashover even punctures to cause porcelain vase to occur.
The applicant has declared the patent that name is called " altogether case enclosed busbar hot-air maintenance device " on the same day, solves the problems referred to above, but in this technical scheme, because the hot blast air quantity needed is comparatively large, when hot blast circulates in cab signal box time, can produce noise; In addition, after hot blast circulates for a long time, owing to not processing the hot blast containing dust, impurity and steam in discharge pipe, so the hot blast of blower fan blowout can produce secondary pollution to porcelain vase.
Summary of the invention
The purpose of this utility model is: overcome the deficiencies in the prior art, a kind of common case enclosed busbar with maintenance function is provided, by blower fan by heating after wind to the porcelain vase in cab signal box, the steam on porcelain vase surface, impurity and dust are blown away, remain the drying around porcelain vase and cleaning, prevent porcelain vase flashover, even puncture and lose insulation property; By discharge pipe, the hot blast also had surplus heat in cab signal box is introduced blower fan again, improve the efficiency of heating surface blowing to hot blast in cab signal box, reduce energy consumption; Sealed by cab signal box top blind flange and opening and arrange, and cover plate is cover plank frame, can prevent extraneous dust, impurity or rainwater from entering in cab signal box; By the effect by annular tuyere, hot blast is dried separately to porcelain vase, hot blast efficiency can not only be improved, reduce the air quantity of hot blast, reduce the energy consumption of blower fan, reduce the noise of hot blast in cab signal box; Discharge pipe, by the effect of dust cleaning apparatus and dehydrating unit, can ensure that the wind that blower fan blows out is clean, dry, avoid the secondary pollution of porcelain vase.
Technical solution adopted in the utility model is:
There is the common case enclosed busbar of maintenance function, comprise the cab signal box being provided with three buses, described bus is fixed on the bottom in cab signal box by porcelain vase, described cab signal box is connected to the switchgear house in multiple building, the bottom of the cab signal box between two buildings is provided with wind chamber, described wind top of chamber corresponds to porcelain vase and is communicated with multiple tuyere, the middle part in described wind chamber is communicated with blast pipe, cab signal box is positioned at and is communicated with discharge pipe respectively with building junction, described blast pipe is communicated with the air outlet of blower fan, discharge pipe is communicated with the air inlet of blower fan, heater is communicated with between described blast pipe and the air outlet of blower fan.
The further improvement project of the utility model is that described porcelain vase is positioned at the tuyere of loop configuration, and tuyere blows to the surface of porcelain vase.
The utility model further improvement project is, the width of described tuyere and the height of porcelain vase match.
The utility model further improvement project is, the inwall in described wind chamber is provided with thermal insulation layer.
The utility model further improvement project is, is communicated with dust cleaning apparatus and dehydrating unit successively between described discharge pipe and blower fan.
The utility model further improvement project is, the top of described cab signal box is provided with multiple opening successively, and the top of described cab signal box is positioned at opening part and is provided with cover plate.
The utility model further improvement project is, described opening is positioned at the top of porcelain vase.
