Description
Technical field
The present invention relates to transformator and control equipment technical field, more specifically, particularly to a kind of Novel intelligent transformer air-cooled switch board.
Background technology
In power system, transformator is a highly important element, and power system is played a very important role by its safe operation.
Transformator is in running, copper loss in winding and the iron loss in iron core produce substantial amounts of heat, if heat can not distribute effectively and timely, transformer body temperature being made too high thus causing the destruction that body is serious, the power transmission and distribution then affecting whole electrical network are properly functioning. Result of study shows that, under surmounting design temperature situation, temperature often raises 6 DEG C, and the service life of transformator will reduce half.
Transformer air-cooled switch board is aiming at 110KV and above employing Natural Oil Circulation Power is air-cooled, forced oil-circulation is air-cooled and the transformator of one of three kinds of types of cooling of forced oil circulation water-cooling and the cooling control system that designs. Its running temperature according to transformator, controls the start-stop of each blower fan or oil pump duplexure in transformator, it is achieved the adjustment of transformer temperature in real time. Automatic or manual control mode can be adopted, it is possible to various information are uploaded backstage and shows and downstream control settings, the whole cooling system of transformator is realized optimum control, reach purpose that is energy-conservation and that extend radiator service life.
Transformer air-cooled switch board is widely applied because its importance has been commercially available, but has also gone out many problems:
1, structural design is unreasonable, and element fault is searched and changes trouble
Because of commercially air-cooled control cabinet inner member adopt sum total arrange unify cabling, one simple fault often to search full cabinet equipment and circuit just can find, and before changing an equipment, generally require first pull down a sheet of, result is old issue handling, creates again new problem.
2, control mode is unreasonable
Air-cooled control cabinet adopts traditional Control, the advantage of this design to be that technology is simple the earliest, and all elements and control logic are all visible, so good reliability, but owing to wiring is complicated, better simply logic control can only be carried out.Along with the development of PLC technology, the automatic control system based on PLC is increasingly becoming the market mainstream. The advantage adopting PLC control system is highly versatile, volume is little, programming in logic is convenient, but system just cannot be properly functioning when PLC exits, and it is totally unfavorable that the transformator requiring high reliability is run by this.
3, the frequent start-stop of cooling device, affects service life
The running temperature of transformator is determined by its bringing onto load size and ambient temperature, is a running parameter, so in order to the running temperature of stabilizing transformer is within the scope of one, its cooling device (blower fan and oil pump) is the frequent start-stop of requirement. And Fraquent start motor can cause being greatly shortened of motor service life.
Transformator running temperature change under normal conditions is a process slowly, and blower fan or oil pump adopt throws, by group, the ladder mode of operation moved back, and often occurs putting into one because temperature rises more, exits the circulating working mode that rear temperature rises again.
4, energy-saving effect is poor
Adopting and throw, by group, the ladder mode of operation moved back, in order to reduce the frequent start-stop of blower fan, even if transformer temperature is normally, cooling device also to continue to run with a period of time, and this section of equipment acting can only be energy loss.
5, equipment is controlled without self-checking function
The operating incipient fault of motor cannot be predicted in advance.
