Description

Technical Field

[0001] The present invention relates to the technical field of transformer full inspection, and in particular to a transformer full inspection device and method. Background Art

[0002] A transformer is a device that uses the principle of electromagnetic induction to change AC voltage. Its main components are the primary coil, the secondary coil, and the iron core (magnetic core). The main functions are: voltage conversion, current conversion, impedance conversion, isolation, voltage stabilization (magnetic saturation transformer), etc. Transformers are basic equipment for power transmission and distribution, and are widely used in industries, agriculture, transportation, urban communities, and other fields. There are about 17 million transformers in operation in my country, with a total capacity of about 11 billion kilovolt-amperes. Transformer losses account for about 40% of power transmission and distribution losses, and have great energy-saving potential. In order to accelerate the promotion and application of high-efficiency and energy-saving transformers, improve the efficiency of energy resource utilization, and promote green, low-carbon and high-quality development, in January 2021, the Ministry of Industry and Information Technology, the State Administration for Market Regulation, and the National Energy Administration jointly formulated the "Transformer Energy Efficiency Improvement Plan (2021-2023)".

[0003] Among them, the "fault detection method, device, equipment and storage medium for oil-immersed transformers" disclosed in the patent with announcement number "CN116184104B" is also an increasingly mature technology. Its "method includes: obtaining the ratio relationship between all time lengths according to the time lengths for multiple temperature detection components located in different planes to reach the second preset threshold respectively, and outputting a virtual length value that satisfies the ratio relationship at each coordinate point based on the same temperature detection component and generating a virtual spherical surface, adjusting the size of all virtual length values ​​so that all virtual spherical surfaces intersect at an intersection point, and the intersection point is the fault point of the coil group. This application utilizes the characteristic that transformer oil is a uniform medium, combines the ratio value formed by the temperature conduction time to define the radius ratio value of the virtual spherical surface, and changes the radius of all virtual spherical surfaces based on the ratio value to obtain the distance between each temperature detection component and the fault point. It is not necessary to calculate the heat flux of the radiation surface where each temperature detection component is located, thereby simplifying the calculation process.

[0004] However, the above-mentioned fault detection method and device design of the oil-immersed transformer have the following disadvantages: the existing transformer detection device only detects the appearance and structure of the transformer to determine whether the transformer is qualified, and does not detect the voltage and leakage of the transformer, which is likely to cause safety hazards during the use of the transformer.

A transformer full inspection method, characterized in that: A transformer full inspection device according to any one of claims 1 to 7, characterized in that it comprises the following steps: Step 1: firstly, placing the transformer in a detection shell (202) to detect the structure of the transformer; the size of the detection shell (202) is cast according to the standard outer side of the transformer; Secondly, the second electric telescopic rod (206) at the top of the L-shaped fixing frame (205) is extended and retracted to drive the first electric clamp (207) to clamp and move the transformer inside the detection shell (202); Then, the transformer is moved to one end of the first fixed frame (1) by means of a feeding mechanism (2), and then the transformer is hoisted onto the voltage detection mechanism (4) by means of a hoisting mechanism (3); Step 2: When testing the voltage of the transformer, the pressing plates at one end of the two third small electric telescopic rods (4015) clamp the transformer, and the H-shaped frame (406) is pushed close to the transformer by the second small electric telescopic rod (405), so that the cooperation between the interlaced column (407) and the telescopic spring (408) facilitates the voltage detector (409) to detect the voltage of the transformer; Step three: the leakage detector (503) cooperates with the first electric telescopic cylinder (501) to perform leakage detection on the transformer.
