In, the system shifted to transformer oil.
Background technology
Effect of the transformer in power system is voltage of transformation, in favor of the transmission of power.The boosted transformer of voltage
After boosting, it is possible to reduce line loss, the economy of power transmission is improved, the purpose of remote power transmission is reached.And step-down transformer is then
Can be the use voltages at different levels required for user high-voltage variable, the need for meeting different user.Transformer it is main by casing, absolutely
Edge sleeve pipe, conservator, radiator, iron core and winding are constituted.Transformer-cabinet (i.e. fuel tank) is inner to fill transformer oil, iron core and winding
It is immersed in transformer oil.There is conservator on fuel tank top, connected by the first oil pipe with casing.Casing is circumscribed with radiator, radiating
Many radiating tubes are arranged in device, are connected by the second oil pipe and the 3rd oil pipe with radiator.First is provided with second oil pipe
The second butterfly valve is provided with butterfly valve, the 3rd oil pipe, between the open and close controlling casing and radiator by the first butterfly valve and the second butterfly valve
Whether connect.The heat energy that operating iron core is produced with winding raises transformer oil temperature, the high transformer oil density of temperature
It is smaller, ascend into radiating tube, transformer oil temperature reduction, density increase after radiating tube internal circulation flow, in radiating tube
Decline reenters casing, and therefore, the heat of iron core and winding can be distributed by the Natural Circulation of transformer oil.
With the sustained and rapid development of national economy, the trend of sustained and rapid development is presented in China's power industry, various big
The application of type transformer is also more and more.In use, local damage occurs, it is necessary to change corresponding attached in high-power transformer
Part.Common practice is as shown in Figure 1 and Figure 2.Fig. 1 is directed to the situation that transformer-cabinet 21 needs to overhaul.Traditional way
It is：Close the first butterfly valve 212 and the second butterfly valve 213, afterwards open positioned at the bottom of casing 21 bottom valve 214 and with outside

The present embodiment has also listed the multidirectional transformer oil transfer system two in capital construction and maintenance work and specifically should
With case, as described below：
The first situation is during transformer equipment capital construction is installed.When transformer capital construction is installed, transformer 2
Casing 21 is generally adopted by the mode with oil transport, and the oxidation of the internal unit of transformer 2 can be avoided to make moist.But transformer 2 is pacified
The seal for leading to transformer high and low pressure lead outside casing 21, i.e. high and low pressure insulating sleeve (insulator are needed after installing
Pipe) and be fixed on outside casing 21.Traditional mode of operation is expelled to the transformer oil in casing 21 in the Oil Tank 3 of outside
Storage, after the installation of high and low pressure lead is fixed, then by oiling equipment, such as transformer oil is refilled case by oil filter 4
In body 21.Using the multidirectional transformer oil transfer system described in the present embodiment, after casing 21 is installed, radiator is first installed
23 and its internal radiating tube, the first butterfly valve 212 is then shut off, the second butterfly valve 213 is opened, for there was only a set of vacuum extractor
Multidirectional transformer oil transfer system, close the first connecting tube 121 on the first control valve 131, open the second connecting tube 122
On the second control valve 132；For there is the multidirectional transformer oil transfer system of two sets of vacuum extractors, close in connecting tube 12
The first control valve 131, open the radiator control valve 13a on radiator connection 12a, no matter which kind of mode, all may be used
So as to be connected between vacuum extractor and radiator 23, start vacuum means and postpone, radiator 23 is in negative pressure state, casing 21
In transformer oil by the 3rd oil pipe 216, flow through the second butterfly valve 213, be transferred in radiator 23, in casing 21 pasta decline
To when exposing height, voltage lead wires, you can operated accordingly, by high and low pressure lead lead to the outside of casing 21 and by height,
Low-voltage insulation sleeve pipe (porcelain bushing shell) is fixed.After installation terminates, vacuum extractor, the second control valve 132 or scattered are closed successively
Hot device control valve 13a, opens the first butterfly valve 212, releases after negative pressure state, and transformer oil will be due to the effect of gravity, weight
New stream enters in casing 21.Whole process, it is not necessary to oil storage, the oiling equipment such as transport and Oil Tank and oil filter outside, section
Manpower and materials have been saved, underground station and the narrow and small place of job area is particularly suitable for use in.
Second of situation is during the device maintenance and defect elimination work after transformer equipment puts into operation.Now only
Enumerating casing 21 needs maintenance or the concrete operations of defect elimination.Those skilled in the art know about, between casing 21 and conservator 22
Connected by the first oil pipe 211, oil pipe control valve is also equipped with first oil pipe 211, to control casing 21 and conservator
Whether connected between 22.When casing 21 and radiator 23 are each filled with transformer oil, the first butterfly valve 212 and the first oil are first turned on
Oil pipe control valve on pipe 211；For there was only the multidirectional transformer oil transfer system of a set of vacuum extractor, close second and connect
The second control valve 132 in adapter 122, opens the first control valve 131 in the first connecting tube；For there is two sets to vacuumize
The multidirectional transformer oil transfer system of device, the radiator control valve 13a closed on radiator connection 12a opens connection
The first control valve 131 on pipe 12；No matter which kind of mode, can make to connect between vacuum extractor and conservator 22, start
Vacuum means are postponed, and the transformer oil that conservator 22 is in negative pressure state, radiator 23 is transferred to conservator by the first oil pipe 211
In 22, after conservator 22 is full of, the oil pipe control valve closed on the first oil pipe 211；Afterwards, the first butterfly valve 212 is closed, is opened
Second butterfly valve 213；For there was only the multidirectional transformer oil transfer system of a set of vacuum extractor, close in the first connecting tube 121
The first control valve 131, open the second connecting tube 122 on the second control valve 132；For there is two sets of vacuum extractors
Multidirectional transformer oil transfer system, the first control valve 131 closed in connecting tube 12 is opened on radiator connection 12a
Radiator control valve 13a；No matter which kind of mode, can make to connect between vacuum extractor and radiator 23, make conservator 22
Do not connected between casing 21, make to connect between radiator 23 and casing 21.Start vacuum means to postpone, radiator 23 is in negative
Transformer oil in pressure condition, casing 21 is flowed through the second butterfly valve 213, is transferred in radiator 23, case by the 3rd oil pipe 216
The pasta of body 21 declines, and corresponding device maintenance or defect elimination work can be carried out to casing 21.After maintenance terminates, close successively
Vacuum extractor, the second control valve 132 or radiator control valve 13a, open the first butterfly valve 212, release negative pressure state
Afterwards, transformer oil will be back flowed back into casing 21 due to the effect of gravity.Whole process, transformer oil is all in transformer 2
Inner loop, the Oil Tank 3 without being expelled to outside, it is to avoid the secondary pollution to transformer oil, simplifies maintenance step, saves
Maintenance cost, shortens maintenance time.
Obviously, above-described embodiment is only intended to clearly illustrate example, and the not restriction to embodiment.It is right
For those of ordinary skill in the art, can also make on the basis of the above description it is other it is various forms of change or
Change.There is no necessity and possibility to exhaust all the enbodiments.And the obvious change thus extended out or
Among changing still in the protection domain of the invention.
