Technical Field

Background
The shunt reactor is an important reactive compensation device in the power system, and can improve the stability and reliability of the power system. However, since the shunt reactor has high voltage level, strong vibration and magnetic leakage are large, and the abnormal gas production problem inside the reactor is serious. This is because a large amount of gas such as hydrogen, nitrogen, etc. is generated during the operation of the reactor due to electromagnetic induction, electrochemical reaction, etc. The existence of the abnormal gases can have adverse effects on the normal operation of the reactor, such as reducing the insulation performance of insulating oil, accelerating insulation aging and thermal decomposition, and further causing serious accidents such as fuel tank explosion and the like.

In order to solve the problem, the existing on-line monitoring device for the insulating oil of the shunt reactor adopts methods of oscillation, degassing and the like so as to reduce the gas content in the insulating oil. However, this approach has some drawbacks. Firstly, the time of oscillation and degassing is long, and the gas content in the reactor cannot be monitored in real time.

Detailed Description
The present invention will be further described with reference to the accompanying drawings and specific examples, which are not intended to be limiting, so that those skilled in the art will better understand the invention and practice it.
The application provides a shunt reactor state diagnosis method, which comprises the following steps:

When the second multi-frequency ultrasonic sensor detects that the content of the insulating oil is increased and/or the breakdown voltage is reduced to exceed the usable range, the oil storage assembly is poor in sealing and needs to be shut down for maintenance;
when the second multi-frequency ultrasonic sensor detects that the moisture content and breakdown voltage of the insulating oil are in the usable range, subsequent operation can be performed;
S3, when the second multi-frequency ultrasonic sensor detects that the moisture content and breakdown voltage of the insulating oil are in the available range, the oil tank supplies oil to the emergency oil discharge pool, and at the same time, the moisture content and breakdown voltage of the insulating oil in the corresponding transmission process are detected through the at least one oil discharge multi-frequency ultrasonic sensor and judged:
when the oil outlet multi-frequency ultrasonic sensor detects that the content of the insulating oil is increased and/or breakdown voltage is reduced abnormally, the corresponding oil outlet position is indicated to be abnormal, and shutdown maintenance is needed;
When the oil outlet multi-frequency ultrasonic sensor detects that the moisture content and breakdown voltage of the corresponding insulating oil are in the available range, the device can be normally put into use.
The shunt reactor state diagnosis method provided by the embodiment of the application realizes accurate measurement of the moisture content and breakdown voltage of the insulating oil in each position of the device through the arrangement of the plurality of multi-frequency ultrasonic sensors, and can be used for targeted positioning maintenance.
In the industry, the breakdown voltage of insulating oil is reduced, that is, under the specific electric field condition, the maximum voltage value born by the insulating oil is reduced, the original insulating performance cannot be maintained, and destructive discharge, namely breakdown, occurs. In general, the breakdown voltage of insulating oil is an important indicator for measuring the insulating performance of insulating oil, and reflects the voltage-tolerant capability of the oil in electrical equipment.
When a trace amount of moisture is contained in the insulating oil, even if such moisture does not cause a significant decrease in breakdown voltage of the oil, a potential effect may be exerted on the insulating performance of the oil. The presence of micro water in the oil may cause impurities or water molecules in the oil to move under the action of an electric field, so-called "bridging" phenomenon is formed, and these micro conductive channels may cause the insulation performance of the oil to be lowered. Although such micro-water may not immediately result in a significant drop in breakdown voltage, it still needs to be monitored and evaluated through rigorous testing to ensure proper operation and safety of the electrical equipment. Therefore, the breakdown point and the water content of the insulating oil are comprehensively evaluated through the multi-frequency ultrasonic sensor, so that the accuracy of the detection result is improved to the greatest extent.
Based on this, in this embodiment, the oil-out multi-frequency ultrasonic sensor specifically includes a third multi-frequency ultrasonic sensor, a fourth multi-frequency ultrasonic sensor, and a fifth multi-frequency ultrasonic sensor, when the second multi-frequency ultrasonic sensor detects that the moisture content and breakdown voltage of the insulating oil are within the usable ranges, the oil tank is made to supply oil to the emergency oil drain pool, and meanwhile, the moisture content and the breakdown voltage of the insulating oil in each corresponding transmission process are detected and judged through the third multi-frequency ultrasonic sensor, the fourth multi-frequency ultrasonic sensor, and the fifth multi-frequency ultrasonic sensor respectively:
When one or more of the third multi-frequency ultrasonic sensor, the fourth multi-frequency ultrasonic sensor and the fifth multi-frequency ultrasonic sensor detect that the content of the insulating oil and water is increased and/or breakdown voltage is reduced abnormally, the corresponding oil outlet position is indicated to be abnormal, and shutdown maintenance is needed;
When the third multi-frequency ultrasonic sensor, the fourth multi-frequency ultrasonic sensor and the fifth multi-frequency ultrasonic sensor measure that the moisture content and the breakdown voltage of the insulating oil are in the available ranges, the device can be normally put into use.
Further, the first multi-frequency ultrasonic sensor, the second multi-frequency ultrasonic sensor, the third multi-frequency ultrasonic sensor, the fourth multi-frequency ultrasonic sensor and the fifth multi-frequency ultrasonic sensor are respectively connected with the electric valve, wherein when one or more sensors detect abnormality, the corresponding electric valve is closed.
