The land control center is provided with a display and control module. The oil sample circulating collection chamber is used for circularly collecting a transformer oil sample; the oil sample is regularly extracted from the oil sample circulation collection chamber by the oil dissolved gas on-line monitoring module (namely the first monitoring module), then the oil dissolved gas is extracted, the type and the concentration of the dissolved gas are analyzed through gas chromatography, data processing is carried out, and the processing result is sent to the communication module; other index monitoring modules (i.e., second monitoring modules) include monitoring of oil temperature, water content, acidity, and other indices.

In the embodiment of the application, the transformer oil sample is collected through the oil sample circulation collection chamber.

Further, in the embodiment of the present application, the first monitoring module is specifically configured to:

Further, in embodiments of the present application, the dissolved gas includes at least H 2 、CH 4 、C 2 H 6 、C 2 H 4 、C 2 H 2 、CO、CO 2 、O 2 And N 2 One of them.
The insulating oil containing different hydrocarbon radicals, e.g. CH 3 、CH 2 And CH, linked by a C-C bond. The C-H and C-C bonds will be broken down by electrical or thermal failure and then recombined into hydrogen (H 2 ) And hydrocarbon gases (e.g. CH 4 、C 2 H 6 、C 2 H 4 And C 2 H 2 ). In addition to hydrocarbon gases, some solid products of carbon and hydrocarbon polymers may also be produced, such as X-wax, n-octane (C 8 H 18 ) And n-hexane (C) 6 H 14 ). The energy to cleave the C-H, C-C, c=c and c≡c bonds increases progressively from left to right. The failure gases generated by different failures are also different due to the different cracking energies of the various bonds. The concentration and type of fault gas is related to the severity of the fault and the type of fault.
In a partial discharge (Partial discharge) failure of the corona type, hydrogen is the gas that is mainly recombined due to the low bond energy of the C-H bonds, which are more easily broken. Hydrogen starts to be produced at 150℃and its quantity increases with increasing temperature, when high energy discharge (cracking) or high temperature failure (T>700 c) occurs, the hydrogen content reaches a fairly high level. Hydrogen is therefore a powerful fault indicator for all types of faults. C (C) 2 H 4 And C 2 H 2 High energy is required for the formation of (a), which means that these gases can indicate the occurrence of a severe fault. Even a small amount of C 2 H 2 But also high energy faults in the transformer.
CO and CO 2 May also be formed in an oil-immersed transformer. They are mainly derived from the thermal decomposition of cellulose insulation. In addition, oxidation of insulating oil is also formedAnother cause of carbon oxides.
Oxygen and nitrogen may also be present as air may remain during manufacture or leakage. Thus, 9 kinds of fault gases, namely hydrogen (H) 2 ) Hydrocarbon gas (CH) 4 、C 2 H 6 、C 2 H 4 And C 2 H 2 ) Carbon oxides (CO, CO) 2 ) And atmospheric gas (O) 2 、N 2 )。
Further, in the embodiment of the present application, the second monitoring module is specifically configured to:
extracting a second transformer oil sample from the oil sample circulation collection chamber, and monitoring the oil temperature change of the second transformer oil sample in real time to obtain monitoring data of the oil temperature;
and detecting the water content and the acid value of the second transformer oil sample according to the second preset time length, and generating a detection result of the water content and the acid value.
In the embodiment of the application, the oil temperature is monitored in real time, and the running condition of the transformer can be reflected more timely by the real-time monitoring because the oil temperature changes rapidly when the transformer fails.
In this embodiment of the application, detect water content and acidity to the timing section, can set up the detection period length according to transformer life and running state in the second monitoring module, because these two indexes change slowly, need not real-time supervision.
In the embodiment of the application, the water content is the water content existing in the oil product. The presence of free water in the oil or when fibrous impurities are encountered with the dissolved water, will reduce the electrical strength of the oil. The water content in the oil is controlled to be a lower value, so that on one hand, the formation of free water in the oil is prevented when the temperature is reduced, and in addition, the water content in the fiber insulation is also beneficial to control, and the aging rate of the oil paper insulation can be reduced. The water content is increased, so that the insulation performance can be directly influenced, the ageing of insulating oil and insulating paper is accelerated, and the running reliability and the service life of equipment are influenced.
In the examples herein, the acid number is the number of milligrams of potassium hydroxide consumed by the acidic component in 1g of test oil under the prescribed conditions. The acid number of the new oil can reach a very low level unless contaminated. The acid value of the oil after oxidation test is one of the important indexes for evaluating the oxidation stability of the oil. It is a main index reflecting the early degradation stage of oil and thus is also an index of running performance.
In the embodiment of the application, the operation state of the transformer is monitored by monitoring the indexes such as the oil temperature, the water content and the acidity.
Further, in an embodiment of the present application, the second monitoring module is further configured to:
when the monitoring data of the oil temperature is larger than a first preset threshold value, judging that the transformer fails, and generating a fault warning;
when the detection result of the water content is larger than a second preset threshold value, judging that the transformer fails, and generating a fault warning;
and when the detection result of the acid value is larger than a third preset threshold value, judging that the transformer fails, and generating a fault warning.
Further, in an embodiment of the present application, the display and control module includes:
the land display and control unit is used for receiving the judging result and the detecting result and displaying the monitoring state of the transformer in real time according to the judging result and the detecting result;
the land display and control unit is also used for sending a control signal to the offshore display and control unit according to the monitoring state of the transformer;
and the offshore display and control unit is used for receiving the control signal and controlling the running state of the transformer according to the control signal.
In this embodiment of the application, the communication module performs real-time data transmission with the display and control module of the land control center, and an analyst of the land control center can send a control signal to the communication module of the offshore platform according to the data analysis result, and the communication module sends the control signal to the offshore control module and controls the running state of the transformer. Meanwhile, the monitoring state and the control condition can be displayed in real time in the offshore display module. In addition, the offshore control module can be manually operated on the offshore platform to control the running state of the transformer.
