Description
Technical field
The utility model relates to a kind of isolated-phase enclosed bus hot-air drying device, and especially a kind of portable isolated-phase enclosed bus hot-air drying device belongs to electrical equipment technical field.
Background technology
Isolated-phase enclosed bus is the big current transmission device that is widely used in 500MW and above generator lead-out wire loop and station-service duplexure, is a kind of transmission of electricity closed conduit, when enclosed busbar moves; Air themperature in the bus shell generally than ring mirror temperature high 30 ℃～50 ℃; After enclosed busbar was out of service, temperature can slowly descend, until reaching ambient temperature; Be easy to generate condensation in this process; Thereby reduce the insulation property of bus,, just might have an accident if at this moment enclosed busbar puts into operation again.For preventing condensation, mainly take three kinds of methods at present, i.e. pressure-fired aeration, dry maintenance method and hot blast maintenance method.The pressure-fired aeration is through charging into dry air in bus shell; Make the bus shell internal pressure greater than ambient pressure, stop outside humid air to get into, this method is higher to the sealing requirements of bus shell; The plant maintenance workload is big, is difficult to reach work preferably.Dry maintenance method is that the isolated-phase enclosed bus two ends are connected with dried-air drier, removes airborne moisture in the bus shell through air circulation, makes air humidity reduction in the bus shell, and this method energy consumption is big, and noise is big during work.Existing hot blast care device all is fixed, and every cover bus all need be equipped with a cover hot blast care device, and floor space is big, and electricity consumption of equipment is many, and cost is high.
Summary of the invention
The purpose of the utility model provides a kind of simple in structure, floor space is little, convenience is mobile, cost is low portable isolated-phase enclosed bus hot blast care device.
The utility model is achieved through following technical scheme:
A kind of portable isolated-phase enclosed bus hot blast care device; Comprise travelling car, be successively set on junction box, drive motors, blower fan, the air heater of travelling car one side; Said drive motors, blower fan are fixed on the travelling car base through holder; The drive motors belt pulley is connected with the blower fan belt pulley through belt; Blower fan top is provided with muffler, and end flanges communicates with the blower fan input under the muffler, and the air heater two ends are fixedly supported on respectively behind the travelling car on the wing base through support; The blower fan output is connected with the air heater input through tube connector, and the air heater output is connected with three-phase enclosed busbar total inlet pipe through flexible steel in flat section tubing.
The purpose of the utility model can also further realize through following technical measures.
Aforesaid portable isolated-phase enclosed bus hot blast care device, the flexible steel in flat section tubing between wherein said blower fan output and the air heater input is provided with air cleaner.
Aforesaid portable isolated-phase enclosed bus hot blast care device, wherein said flexible steel in flat section tubing is a stainless steel flexible hose.
Aforesaid portable isolated-phase enclosed bus hot blast care device, wherein said blower fan one side also is provided with barometer.
The utility model is simple in structure, volume is little, and conveniently moving can supply many cover buses to use successively, and each power plant only need be equipped with a cover the utility model and get final product, and service efficiency is high, and equipment energy consumption is low, and cost is low.Field wiring is flexible, and the bus maintenance is effective, and effect on moisture extraction is good.Adopt the flexible steel in flat section tubing field wiring flexible, reduce the length that is fixedly connected pipe, make flow speed increase, maintain effectively, effect on moisture extraction is better.
Advantage of the utility model and characteristics will illustrate through the non-limitative illustration of following preferred embodiment and explain that these embodiment only provide with reference to accompanying drawing as an example.
Description of drawings
Fig. 1 is the structural representation of the utility model;
Fig. 2 is the left view of Fig. 1.
Embodiment
Below in conjunction with accompanying drawing and embodiment the utility model is described further.
Like Fig. 1, shown in Figure 2; The utility model comprises travelling car 1, is successively set on the junction box 2 of travelling car 1 front side, drive motors 3, blower fan 4, air heater 5, and drive motors 3, blower fan 4 are fixed on travelling car 1 base 11 through holder 6, and drive motors belt pulley 31 is connected with blower fan belt pulley 41 through belt 7; Blower fan 4 right sides are provided with barometer 30; Its top is provided with muffler 8, muffler 8 upper ends and atmosphere, and 8 times end flanges of muffler are fixedly connected with blower fan 4 inputs.Air heater 5 two ends are fixedly supported on respectively on the travelling car 1 back wing base 12 through support 9; Blower fan 4 output pipelines are connected with air heater 5 inputs; Air heater 5 outputs link to each other with bus through flexible steel in flat section tubing 10; Flexible steel in flat section tubing 10 is a stainless steel flexible hose in the present embodiment, long service life, and anticorrosion ability is good.Tube connector 40 between blower fan 4 outputs and air heater 5 inputs is provided with air cleaner 20; To pass through 5 heating of filtered air input air heater; The hot blast of air heater 5 outputs is connected dry three-phase enclosed busbar through flexible steel in flat section tubing 10 with three-phase enclosed busbar total inlet pipe.The pipeline of the utility model is through the circulation of ball valve control air, and wiring is few, and control is convenient.
After enclosed busbar is out of service, flexible steel in flat section tubing 10 pipe end flanges are connected with three-phase enclosed busbar total inlet pipe, start drive motors 3 and air heater 5; Under drive motors 3 drives; Blower fan 4 constantly is blown into air to air heater 5, and air gets in the air heater 5 through tube connector 40 along the direction of arrow in the figure, and the air after the heating successively gets into respectively in every phase enclosed busbar shell through flexible steel in flat section tubing 10, three-phase enclosed busbar total inlet pipe; Along with gas constantly gets into; Wet gas in the three-phase enclosed busbar shell is pulled away, and temperature raises in the bus shell, thereby prevents to produce in the bus condensation phenomenon.Travelling car 1 can be shifted onto to be needed by the dry three-phase enclosed busbar, and the utility model is connected with next cover bus, can carry out the drying maintenance.
Except that the foregoing description, the utility model can also have other execution modes, and all employings are equal to the technical scheme of replacement or equivalent transformation formation, all drop in the protection range of the utility model requirement.
