Abstract
The utility model discloses a take enclosed bus of pressure -fired system, air compressor machine, filtration system, drying system, solenoid valve, check valve, enclosed bus, pressure transmitter that take enclosed bus of pressure -fired system is connected by the pipeline in order constitute, filtration system comprises automatic drain, drying system includes the desicator jar, the aluminium oxide is equipped with in the inside lower floor of desicator jar, and allochroic silica gel is equipped with on the upper strata. Consequently, through using this take enclosed bus of pressure -fired system, solve the desicator and do not had the regeneration function and do not have the problem that the change in properties was indicateed, the filter capacity is poor and do not have automatic flowing back function, guaranteed compressed air's quality.
Description
Technical field
The utility model relates to technical field of power generation, particularly a kind of enclosed busbar with pressure-fired system.
Background technology
In the generating set in current most thermal power plant at home, enclosed bus of generator because of have easy to use, steel construction heating less, security reliability is high, operation maintenance workload is relatively little, the advantage such as not affected by environment and being widely used.Because enclosed busbar is relative closure, when ambient temperature declines or load current reduction causes bus temperature to reduce, the air pressure in enclosed busbar will reduce, and will inhale people's air from some leakage points, bring moisture, dust etc. into, bring potential safety hazard to the operation of enclosed busbar.For preventing extraneous moisture, dust enters, and what electric closed bus adopted mostly is absorption type micro positive pressure device, provides the compressed air of clean dry in enclosed busbar, but pressure-fired system exists following shortcoming at present:
1) original system is without special moisture filter device, only has a filtering pressure reducing valve, filter capacity extreme difference and without automatic liquid-drainage function, do not have moisture filter effect.As pressure-reducing valve not blowdown on time, oil, water hydrops directly will enter drier, cause drier to lose efficacy, liquid may be caused to enter enclosed busbar, serious threat unit safety operation time serious.
2) drier is without regeneration function and without performance change instruction, whether increase with running time, drying capacity weakens gradually, and cannot monitor out drier and lost efficacy, the insulating properties directly affecting enclosed bus of generator once drier lost efficacy.
Summary of the invention
The purpose of this utility model is to provide a kind of enclosed busbar with pressure-fired system, the enclosed busbar of this band pressure-fired system solves drier without regeneration function and without performance change instruction, filter capacity difference and without the problem of automatic liquid-drainage function, ensure that compressed-air actuated quality.
To achieve these goals, the utility model provides a kind of enclosed busbar with pressure-fired system, the air compressor machine that the enclosed busbar of described band pressure-fired system is connected in turn by pipeline, filtration system, drying system, magnetic valve, non-return valve, enclosed busbar, pressure transmitter form, described filtration system is made up of automatic draining device, described drying system comprises drier tank, aluminium oxide is equipped with in the inner lower floor of described drier tank, and discolour silica gel is equipped with on upper strata.
Preferably, described automatic draining device is filtration system step by step.
Preferably, described filtration system step by step comprises single filter and secondary secondary filter.
Preferably, described drier tank is made up of transparent material.
Preferably, described pipeline adopts rigid plastics flexible pipe.
Pass through technique scheme, the beneficial effects of the utility model are: by transforming former filtering pressure reducing valve as step by step filtration system, through single filter and secondary secondary filter, eliminate moisture, ensure that compressed-air actuated quality, optimized by former drier, the drier life-span can larger prolongation, by observing, attendant directly can judge whether drier lost efficacy.
Other feature and advantage of the present utility model are described in detail in detailed description of the invention part subsequently.
Accompanying drawing explanation
Accompanying drawing is used to provide further understanding of the present utility model, and forms a part for description, is used from explanation the utility model, but does not form restriction of the present utility model with detailed description of the invention one below.In the accompanying drawings:
Fig. 1 is the closed busbar system figure of the band pressure-fired system that the utility model preferred embodiment provides.
Detailed description of the invention
Below in conjunction with accompanying drawing, detailed description of the invention of the present utility model is described in detail.Should be understood that, detailed description of the invention described herein, only for instruction and explanation of the utility model, is not limited to the utility model.
As shown in Figure 1, the utility model provides a kind of enclosed busbar with pressure-fired system, and the air compressor machine that the enclosed busbar of described band pressure-fired system is connected in turn by pipeline, filtration system, drying system, magnetic valve, non-return valve, enclosed busbar, pressure transmitter form, pipeline adopts hard conveying flexible pipe, system and drying system filter the compressed air that air compressor machine produces after filtration, dewater, finally be filled into after drying in enclosed busbar cylinder, the force value in enclosed busbar measured by pressure transmitter, convert surveyed force value to curtage signal, magnetic valve and enclosed busbar pressure are interlocked, by enclosed busbar Stress control between 0.5KPa to 1.8KPa, bus is entered to prevent dust and outside clammy air, when the pressure of enclosed busbar is at below 0.3MPa, compressed air enters enclosed busbar, simultaneously, non-return valve prevents reverse air flow, the air pressure in enclosed busbar cylinder is made to remain at slight positive pressure state, prevent extraneous containing moisture, the air of dust enters in enclosed busbar cylinder.
Particularly, filtration system is made up of automatic draining device, automatic draining device has two filter cylinders, single filter can be carried out and secondary secondary filter is filtered step by step to air, ensure that compressed-air actuated quality through single filter and secondary secondary filter, solve former filtration devices ability extreme difference and without the problem of automatic liquid-drainage function.
Described drying system comprises drier tank, described drier tank is made up of transparent material, aluminium oxide is equipped with in its inner lower floor, discolour silica gel is equipped with on upper strata, aluminium oxide can play dry effect, discolour silica gel absorbs moisture medium color and changes, by observation, attendant directly can judge whether drying system lost efficacy, solve that drying system cannot monitor problem.
To sum up, the enclosed busbar of the band pressure-fired system that the utility model provides is by transforming former filtering pressure reducing valve as step by step filtration system, through single filter and secondary secondary filter, eliminate moisture, ensure that compressed-air actuated quality, optimized by former drier, the drier life-span can larger prolongation, by observing, attendant directly can judge whether drier lost efficacy.
Below preferred embodiment of the present utility model is described by reference to the accompanying drawings in detail; but; the utility model is not limited to the detail in above-mentioned embodiment; within the scope of technical conceive of the present utility model; can carry out multiple simple variant to the technical solution of the utility model, these simple variant all belong to protection domain of the present utility model.
