Description
Technical field
The invention belongs to Repair of Transformer auxiliary equipment technical field, particularly relate to a kind of high voltage side of transformer inlet wire cable fuel tank three-phase combination unit.
Background technology
Traditional high voltage side of transformer inlet wire adopts oil filled bushing to draw more, because the integral body of transformer is very high, therefore should not go deep into center, and in addition because the room frame of transformer room is very high, so cost is high, and waste land resource.
Along with increasing of indoor station construction, the needs of building a station in order to meet center, high voltage side of transformer long cable section of ingoing line fuel tank is applied on new clothes transformer more and more.It is to have increased a cable fuel tank at the rising seat top of every phase, and this class transformer has reduced the size of whole transformer really, has saved construction area and space.
But, therefore because be disconnected between threephase cable fuel tank, under original condition of work, to drain the oil, vacuumize, vacuum oil link must divide and carry out for three times, in work, the inventor finds that this threephase cable fuel tank exists following shortcoming:
1, three-phase is carried out the work respectively, entirely so can make the operating time increase by three times, and interruption duration is increased greatly, and the assurance of annual power supply reliability is caused and had a strong impact on.
2, former having ready conditions down, the vacuum oil stage can not monitor injection flow well, easily causes transformer oil to flow backwards into vacuum unit, causes great equipment, economic loss.
3, three-phase vacuumizes respectively, and therefore vacuum degree that can not the other two-phase of fine assurance in vacuum oil can not reach best effect.
4, three-phase is carried out the work respectively repeatedly to open and is stopped oil filtering unit, increases the loss to equipment.
5, repeated work is many, easily causes unnecessary personnel, work waste, makes staff produce thought off one's guard.
Summary of the invention
In order to address the above problem, the object of the present invention is to provide a kind of flexibly, practicality and the high high voltage side of transformer inlet wire cable fuel tank three-phase combination unit of reliability.
In order to achieve the above object, high voltage side of transformer inlet wire cable fuel tank three-phase combination unit provided by the invention comprises a plurality of flanges, many flexible pipes, connector and transition tanks; Wherein transition tank comprises tank body, intake valve and air outlet valve, and the top of tank body is separately installed with an air inlet pipe and an escape pipe, and on air inlet pipe and escape pipe, is separately installed with intake valve and air outlet valve; One end of connector is formed with three oil inlet pipes that are arranged side by side, and the other end is formed with a flowline, on oil pipe, is separately installed with a by-pass valve control, and is connected with respectively a flexible pipe into and out of the outer end of oil pipe; Three flexible pipe outer ends that are connected with oil inlet pipe are connected with respectively a flange, and the flexible pipe outer end being connected with flowline is connected in the air inlet pipe of transition tank removably.
An oil ga(u)ge is installed in the circle wall of described tank body.
The bottom of described tank body is also provided with a blowdown pipe, and blowdown valve is installed on blowdown pipe.
High voltage side of transformer inlet wire cable fuel tank three-phase combination unit provided by the invention has efficient, flexible, simple, practical and reliable property advantages of higher, can further improve maintenance of equipment efficiency, saves manpower and energy resource consumption.Due to simple in structure, flexible for installation and can reduce the input of manpower property.By the use of this device, greatly improved overhaul efficiency, the repair time of tape cable tank transformer has been shortened to 2/3rds, electric energy loss and the devices consume having avoided three-phase maintenance to carry out respectively and caused, improved and vacuumized and the processing quality of vacuum oil, obtained in actual use good effect.
Accompanying drawing explanation
Fig. 1 is high voltage side of transformer inlet wire cable fuel tank three-phase combination unit structural representation provided by the invention.
Embodiment
Below in conjunction with the drawings and specific embodiments, high voltage side of transformer inlet wire cable fuel tank three-phase combination unit provided by the invention is elaborated.
As shown in Figure 1, high voltage side of transformer inlet wire cable fuel tank three-phase combination unit provided by the invention comprises a plurality of flanges 1, many flexible pipes 2, connector 3 and transition tanks 4; Wherein transition tank 4 comprises tank body 5, intake valve 6 and air outlet valve 7, and the top of tank body 5 is separately installed with an air inlet pipe and an escape pipe, and on air inlet pipe and escape pipe, is separately installed with intake valve 6 and air outlet valve 7; One end of connector 3 is formed with three oil inlet pipes that are arranged side by side, and the other end is formed with a flowline, on oil pipe, is separately installed with a by-pass valve control 8, and is connected with respectively a flexible pipe 2 into and out of the outer end of oil pipe; Three flexible pipe being connected with oil inlet pipe 2 outer ends are connected with respectively a flange 1, and flexible pipe 2 outer ends that are connected with flowline are connected in the air inlet pipe of transition tank 4 removably.
An oil ga(u)ge 10 is installed in the circle wall of described tank body 5, for monitoring whether its inner oil level reaches predetermined altitude, thereby judges whether high voltage side of transformer inlet wire cable fuel tank is filled with.
The bottom of described tank body 5 is also provided with a blowdown pipe, and blowdown valve 9 is installed on blowdown pipe.
High voltage side of transformer inlet wire cable fuel tank three-phase combination unit provided by the invention can be drained the oil to high voltage side lead-in cable fuel tank, vacuumized, three operations of vacuum oil.When needs are drained the oil, without using transition tank 4, only the ring flange on three flanges 1 need be connected with the three-phase oil-out on high voltage side lead-in cable fuel tank simultaneously, thus by parallel three phase, then by-pass valve control all on connector 38 is opened, now the oil in high voltage side lead-in cable fuel tank will enter connector 3 inside by three oil inlet pipes on flexible pipe 2 and connector 3, then through flowline, drain in receiving vessel, can utilize the mode of adjusting control valve door 8 apertures to regulate the speed of draining the oil, make the oil pump capacity of Three-Phase Transformer identical.When needs vacuum oil, need to use two covers three-phase combination unit provided by the invention, a set of with transition tank 4 for vacuumizing, the another set of transition tank 4 that do not use is for oiling.First by vacuumizing with the ring flange on three flanges 1 in three-phase combination unit, be connected with the bleeding point of high voltage side lead-in cable oil upper box part simultaneously, thus by parallel three phase, escape pipe on tank body 5 and vacuum pump are joined simultaneously, then the intake valve 6 on by-pass valve controls 8 all on this connector 3 and tank body 5, air outlet valve 7 are opened.Meanwhile, vacuum oil is connected with the three-phase pouring orifice of high voltage side lead-in cable oil lower box part with the ring flange on three flanges 1 in three-phase combination unit simultaneously, thus by parallel three phase, flowline and oil pump on this connector 3 are joined simultaneously, then by-pass valve control all on connector 38 is opened.Start afterwards and vacuumize the vacuum pump being connected with three-phase combination unit, so that Three-Phase Transformer is vacuumized simultaneously.When the vacuum degree of high voltage side lead-in cable fuel tank internal reaches oiling and requires, the oil pump that startup is connected with three-phase combination unit with vacuum oil, so that three-phase is carried out to oiling simultaneously, while having oil to flow in the flowline on connector 3, illustrate that high voltage side lead-in cable fuel tank fills with, close pouring orifice valve on this oil tank body and all valves on above-mentioned two covering devices and vacuum pump, oil pump can complete whole operating process.
