Description

TECHNICAL FIELD

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

[0002] A transformer is a device that uses the principle of electromagnetic induction to change the alternating voltage. The main components are the primary coil, secondary coil and core (magnetic core). The main functions include: voltage transformation, current transformation, impedance transformation, isolation, voltage stabilization (magnetic saturation transformer), etc. Transformers are basic equipment for power transmission and distribution, widely used in industry, agriculture, transportation, urban communities and other fields. There are about 17 million transformers in operation in China, with a total capacity of about 11 billion kilovolt-amperes. Transformer losses account for about 40% of power transmission and distribution power losses, and have great energy-saving potential. In January 2021, the Ministry of Industry and Information Technology, the General Administration of Market Supervision and the National Energy Bureau jointly formulated the "Transformer Energy Efficiency Improvement Plan (2021-2023)".

[0003] The patent with publication number "CN116184104B" discloses a "fault detection method, device and equipment for oil-immersed transformer and storage medium", which is a mature technology. The method includes: obtaining the ratio relationship between the time lengths of the multiple temperature detection pieces located in different planes reaching the second preset threshold value, and generating a virtual sphere based on the virtual length value of the same temperature detection piece at each coordinate point satisfying the ratio relationship. Adjust the size of all virtual length values so that all virtual spheres intersect at a point of intersection, which is the fault point of the coil group. This application utilizes the uniform medium characteristics of transformer oil and the proportional value formed by the temperature conduction time to define the radius proportional value of the virtual sphere. Based on the proportional value, the radius of all virtual spheres is changed to obtain the distance between each temperature detection piece and the fault point, and the heat flux of the radiation plane of each temperature detection piece does not need to be calculated, thereby simplifying the calculation process.

[0004] However, the above-mentioned fault detection method and device for 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 may cause safety hazards during use of the transformer.

A transformer full inspection method, characterized by: A transformer full inspection device according to any one of claims 1 to 3, characterized in that it comprises the following steps: Step 1: First, place the transformer in a detection shell (202) to detect the transformer structure; the size of the detection shell (202) is cast according to the standard transformer outer surface; Secondly, the second electric telescopic rod (206) on the top of the L-shaped fixing frame (205) is extended and retracted to drive the first electric clamp (207) to clamp and remove the transformer inside the detection shell (202); Then, the transformer is moved to one end of the first fixed frame (1) by the provided loading mechanism (2), and then the transformer is hoisted onto the voltage detection mechanism (4) by the provided hoisting mechanism (3); Step 2: When performing voltage detection on 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 3: The leakage detector (503) cooperates with the first electric telescopic cylinder (501) to perform leakage detection on the transformer.

5. A transformer full inspection method according to claim 4, characterized in that: The leakage detector (503) is an integrated leakage detection detector.

6. A transformer full inspection method according to claim 4, characterized in that: The voltage detector (409) is a residual voltage tester.
