Description

Case enclosed busbar hot-air maintenance device altogether
Technical field
The utility model relates to common case enclosed busbar maintenance field, is specifically related to common case enclosed busbar hot-air maintenance device.
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.
Summary of the invention
The purpose of this utility model is: overcome the deficiencies in the prior art, a kind of case enclosed busbar hot-air maintenance device is altogether 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, prevent extraneous dust, impurity or rainwater from entering in cab signal box.
Technical solution adopted in the utility model is:
Case enclosed busbar hot-air maintenance device altogether, 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, be communicated with blast pipe in the middle part of cab signal box between two buildings, cab signal box is positioned at and is communicated with discharge pipe respectively with building junction, and described blast pipe is communicated with the air outlet of blower fan, discharge pipe is communicated with the air inlet of blower fan, is communicated with heater between described blast pipe and the air outlet of blower fan.
The further improvement project of the utility model is, the mouth of pipe of described blast pipe stretches in cab signal box, is dried by the junction, two ends of tuyere to cab signal box and building.
The utility model further improvement project is, the height of described tuyere flushes with the height of porcelain vase, and the width of tuyere is greater than porcelain vase lateral separation.
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.
The utility model further improvement project is, the edge of described cover plate and opening is tightly connected by sealing strip.
The beneficial effects of the utility model are:
The first, altogether case enclosed busbar hot-air maintenance device of the present utility model, 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.
The second, altogether case enclosed busbar hot-air maintenance device of the present utility model, again introduces blower fan by discharge pipe by the hot blast also had surplus heat in cab signal box, improves the efficiency of heating surface blowing to hot blast in cab signal box, reduce energy consumption.
Three, case enclosed busbar hot-air maintenance device altogether of the present utility model, is sealed by cab signal box top blind flange and opening and arranges, and prevents extraneous dust, impurity or rainwater from entering in cab signal box.
