Description
Technical field
It the utility model is related to a kind of vapor liquid heat exchange system, particularly a kind of vapor liquid heat exchange system for rectifier cabinet
System, belongs to heat-exchange system technical field.
Background technology
Excitation system is the important component of synchronous generator, and exciting current is provided for generator.Excellent excitation system
System can ensure operation of the generator reliably with stabilization.Particularly vast capacity generating set comes into operation in recent years so that
Exciting current greatly improves, therefore it is required that the rectifier cabinet of excitation system exports bigger exciting current.The work of excitation system rectifier cabinet
With being that three-phase alternating voltage is rectified into controllable pulsating dc voltage, exciting current is provided to generator excitation winding.Rectification
Cabinet is made up of IGCT, fuse, fan cooling unit and PLC Control cards.Switching loss and the stable state damage of IGCT
Consumption is the most important pyrotoxin of rectifier cabinet, and in addition resistance-capacitance absorption device, fuse and the copper bar of rectifier cabinet also can all produce
Raw loss and heating.The caloric value of large-scale excitation system rectifier cabinet is very big, therefore the cooling of rectifier cabinet is to influence rectifier cabinet to contribute
And an important factor for reliability, and the type of cooling used at present has three kinds of forced air cooling, direct water-cooling and indirect water-cooling modes.
The first type of cooling is forced air cooling mode, and forced air cooling is most widely used in excitation system, use more
Single cabinet two fans or four fan device redundant fashion.The technology maturation, blower fan is easy to maintenance, and rectification cabinet arrangement is simple, and then
The preferred option cooled down by most of excitation producer as rectifier cabinet.Cold wind is pumped into cabinet by blower fan outside cabinet, flows through radiator,
Heat caused by rectifier cabinet IGCT is taken away, is ultimately drained into outside cabinet.Small of excitation is all discharged in thermal power plant's hot-air,
Therefore air-conditioning is needed to small cooling of excitation.But air-conditioning longtime running, particularly summer high temperature weather, its fault rate are very high.
And in hydroelectric power plant, excitation system is largely placed in generator floor, therefore caused hot-air is exhausted directly to whole factory building, undoubtedly
Increase the requirement to power house ventilation system.This external forced air cooling also has many deficiencies of itself, for example its cooling capacity is by ring
The shortcomings of border temperature influences greatly, and dust-proof effect is poor, and noise is big.
Second of type of cooling is direct water-cooling mode, directly rectifier cabinet IGCT is carried out using water-filled radiator cold
But, this is a sealing and circulating water system.Then water-water heat exchanger is reused, by the heat transfer of sealing and circulating water system
Taken away into outer loop water system.This mode solve the first type of cooling well existing for heat be discharged to factory building,
The shortcomings of influenced by ambient temperature big, dust-proof effect difference and noise is big.But this type of cooling has the problem of new again, this is close
Requirement of the closed loop water system to water quality is very high, it is desirable to which the insulating properties of water are high, good airproof performance.And water-filled radiator directly connects
IGCT is touched, so complicated, Maintenance and Repair cost is high.
The third type of cooling is indirect water-cooling mode, and the type of cooling of indirect water-cooling has cooling capacity big, and noise is small,
The features such as anti-dust performance is good, there is the incomparable technical advantage of other types of cooling.This type of cooling is held available for excitation
The situation that amount is big and operating ambient temperature is higher.Heat exchanger is entered by the hot-air of thyristor radiator, hot-air is cold
But.Heat exchanger is a kind of air-cooling apparatus, and its principle is to allow outer circulation cooling water to flow through metallic conduit inner chamber, and heat is empty
Gas flows through metallic conduit outer wall and fin, and then hot-air is cooled, and heat is pulled away.Current existing technology is each
One single water cooling plant is installed to realize cooling, nonredundancy design, if one of failure, single on rectifier bridge
Rectifier cabinet is out of service.And its water cooling plant is switched on and off controlling manually, can not realize intelligent management.Material
Common aluminum alloy water pipe is selected, corrosion resistance and thermal conductivity are not ideal enough, easy incrustation.In order to solve these problems and more
The advantage of indirect water-cooling is played well, develops a kind of vapor liquid heat exchange system for rectifier cabinet.

As shown in Figures 1 to 7, power-equipment 2 has 2, is the 1st power-equipment 2 and the 2nd power-equipment 2；Heat-exchange apparatus 3 has 2
It is individual, it is the 1st heat-exchange apparatus 3 and the 2nd heat-exchange apparatus 3.And the 1st power-equipment 2 and the 1st heat-exchange apparatus 3
In running order, the 2nd power-equipment 2 and the 2nd heat-exchange apparatus 3 are in off working state.
Gas medium circulation loop is the sealing and circulating loop with outside air isolation, in this this loop, gas passage
Gas temperature detector 41, the gas pressure detection device 42 set on pipe 4 monitor to the running status of power-equipment 2, with
The temperature and pressure of gas medium is as logic judgment foundation.When in the gas passage pipe 4 flowed out from the IGCT 11 of rectifier cabinet 1
When the temperature of gas medium is significantly raised, pressure substantially reduces, then the 1st failure of power-equipment 2 is judged.Then pass through controller 6
Undisturbed closes the 1st power-equipment 2 to break down immediately, and is switched to the 2nd power-equipment 2 and is operated.
Fluid temperature detector 51, fluid pressure detector 52, the liquid flux detector 53 set on fluid passage pipe 5
Monitoring to the running status of heat-exchange apparatus 3, logic judgment foundation is used as using the temperature, pressure and flow of liquid medium.When the 1st
The medium pressure liquid difference in fluid passage pipe 5 connected on the individual inlet of heat-exchange apparatus 3 and liquid outlet significantly increases, goes out liquid
The flow in fluid passage pipe 5 connected on mouth significantly reduces, then judges that plugging or leakage etc. occur for the 1st heat-exchange apparatus 3
Failure.By controller 6, undisturbed closes the 1st heat-exchange apparatus 3 to break down immediately（Blocked and the by stop valve 54
1 heat-exchange apparatus 3 connected fluid passage pipe 5 is realized）, and it is switched to the 2nd heat-exchange apparatus 3（Pass through stop valve 54
The fluid passage pipe 5 that is connected with the 2nd heat-exchange apparatus 3 is connected to realize）It is operated.
In summary, it is securely and reliably, practical using a kind of vapor liquid heat exchange system for rectifier cabinet of the present utility model
Property is strong, during using the utility model, when in running order power-equipment or heat-exchange apparatus break down, allows hand over
Be operated to another 1 power-equipment or heat-exchange apparatus, effectively avoid because of power-equipment or heat-exchange apparatus failure and
The situation that can not cool down rectifier cabinet is caused to occur, the situation for avoiding generating set from shutting down occurs, and improves generating equipment operation
Security and stability.
Preferred embodiment of the present utility model is the foregoing is only, it is all at this not to limit the utility model
All any modification, equivalent and improvement made within the spirit and principle of utility model etc., should be included in the utility model
Protection domain within.
