Database Unit 140 can store and judge that the detection limit of the imflammable gas measured belongs to security interval, warning
The standard in which interval in interval and the most interval and the temperature characterisitic corresponding with the kind of imflammable gas.To place of safety
Between, alert interval and abnormal interval be described as follows, when the detection limit of the imflammable gas measured belongs to security interval
(Normal), time, can represent and need not check insulating oil, when detection limit belongs to abnormal interval (Abnormal), can represent
Need to check insulating oil.As middle interval warning interval (Caution) belong to the detection limit according only to imflammable gas without
Method judges whether the situation needing to carry out checking, it may be considered that the temperature of insulating oil or the amount of imflammable gas are in warning interval
Time etc. judge whether to need to check insulating oil.It addition, different types of imflammable gas is by surrounding environment influence (example
Such as, the temperature of insulating oil) degree also can be different, it is therefore desirable to the information of this respect.For temperature characterisitic, need the different of temperature
The most interval temperature T startedabnormal, start the time t that checks required for insulating oilmoveDeng, for the detailed description of this respect
Will be described hereinafter with application.Therefore, every kind of imflammable gas is required for for judging the inspection of imflammable gas measured
Measure belong to security interval, alert interval and abnormal the most interval in the standard in which interval and corresponding with the kind of imflammable gas
Temperature characterisitic, it is therefore desirable to carry out data base system.
Judging unit 130 can receive the detection limit of the imflammable gas measured by insulating oil deterioration diagnostic sensor, and
Judge according to the standard being stored in Database Unit 140 and export the detection limit of measured imflammable gas to belong to place of safety
Between, alert interval and abnormal interval in which is interval.Judging unit needs to electrically connect with Database Unit 140, with can
Enough access Database Unit 140.
Alarm unit 150 receives the temperature of insulating oil, described three-phase current/voltage and the judgement of described judging unit, when
Judging for generating the warning that insulating oil checks time the most interval, when the judgement of judging unit 130 is place of safety of judging unit 130
Between time do not generate insulating oil check warning.Can be according to the temperature of insulating oil when the judgement of judging unit 130 is for warning interval
The temperature characterisitic that degree, three-phase current/voltage are corresponding with the kind with imflammable gas being stored in Database Unit 140 generates
Described warning, will be described in detail in a later process about this respect.
When the judgement of judging unit 130 is for warning interval, alarm unit 150 generates the feelings of the warning that insulating oil checks
Condition can be the situation meeting mathematical expression 1.
[mathematical expression 1]
Wherein, I is the virtual value of the three-phase current measured in load, and r is pole core and the transformer coil of transformator
Resistance value, c is the thermal capacity of whole insulating oil, TabnormalIt is the temperature of abnormal interval beginning, TmeasureIt it is the insulation measured
The temperature of oil, tmoveIt is to start to check the time required for insulating oil.In mathematical expression 1, I2R can be by V2/ r substitutes, wherein
V represents the virtual value of the voltage measured in load.But, when the judgement of judging unit 130 is for warning interval, alarm unit
150 are preferably used value temperature and the described three-phase current/voltage of described insulating oil being averaged in period set in advance,
This is to remove the deviation caused by the residual noise produced when measuring curtage.The described time set in advance is preferred
It it is more than 1 minute, this is because residual noise is the biggest when the described time set in advance is below 1 minute.tmovePermissible
Say it is to checking that place dispatch personnel carries out checking the required time, it may be considered that await orders between personnel and transformator away from
From, prepare the time required for insulating oil of changing of the danger etc. to(for) temperature corresponding with insulating oil kind and determine.Mathematics
The left side of formula 1 is that the temperature of transformer insulation oil reaches abnormal interval required heat, and the right is the heat produced in transformator
Amount.Therefore, when the right is more than the left side, transformator can be evaluated as dangerous.
C and r is the intrinsic value determined by transformator, TabnormalAnd tmoveIt is that the kind according to imflammable gas determines
Value, the value in Database Unit 140 can be stored in.
The current value measured in load is arranged by mathematical expression 1, is then mathematical expression 2.
[mathematical expression 2]
According to mathematical expression 2, utilize and be stored in the T in Database Unit 140abnormal、tmove, C and r pointed out based on
The generation standard of the warning of the electric current of detection.
Communication unit 160 can be by selected from Ethernet, mobile radio communication, WLAN, bluetooth and RF identification
Any one communication network or communication channel, by three-phase current/voltage, the detection limit of imflammable gas and the data of insulating oil temperature
It is sent to the terminal of outside.Be converted to meet such as it addition, communication unit 160 can also possess by the described data of input
IEC61850, DNP, Modbus etc. are used for carrying out the function of the form of the agreement defined in standard of the automation of transformation substations, so that
Communication unit can and Surveillance center 400 between carry out data exchange.
Fig. 3 is to represent that the detection limit according to the imflammable gas measured judges that security interval, warning are interval and abnormal
Interval belongs to the table of the standard in which interval.With reference to Fig. 3, when determining such as hydrogen (H2), acetylene (C2H2), ethylene (C2H4), first
Alkane (CH4), ethane (C2H6), propane (C3H8) etc. the detection limit of imflammable gas time, it is possible to know and belong to security interval, warning
Which interval in interval, the most interval.Lift a concrete instance, if being measured to the hydrogen (H of about 500ppm2), then belong to alert
Accuse interval.
Fig. 4 is the table of the probability representing that the transformator corresponding with the temperature of insulating oil of detection have an accident.Because of with can
The temperature corresponding to kind of combustion property gas, the probability of transformer misoperation is different.With reference to Fig. 4, it is known that hydrogen (H2) compare ethylene
(C2H4) when temperature rises, the danger of maloperation is low.This characteristic can be applied to the t of mathematical expression 1move, therefore at hydrogen
(H2In the case of), can be by tmoveIt is set to than ethylene (C2H4) big.
Fig. 5 is real time load monitoring and the flow chart of insulating oil deterioration diagnosis method of one embodiment of the present of invention.Ginseng
