Description

Technical Field

[0001] The utility model relates to the technical field of pulmonary lobe magnetic shielding, and more specifically, to a test device for detecting the insulation performance of pulmonary lobe magnetic shielding. Background Art

[0002] There are certain limitations in the factory inspection of the magnetic shielding of the lung lobes. Usually, at this stage, only its external dimensions can be inspected, but its critical insulation performance cannot be checked. Generally speaking, the insulation performance of the magnetic shielding of the lung lobes can only be tested when the overall transformer test is carried out. However, if the problem is discovered at this stage, it is often necessary to carry out major rework such as lifting the cover and removing the coils. The impact of this situation is very large, and it will cause a lot of time and cost losses. On the one hand, the operation process of lifting the cover and removing the coils is complicated and time-consuming, which seriously delays the production progress and makes the delivery time of the transformer difficult to determine. On the other hand, major rework not only requires more manpower and material resources, but also may cause potential damage risks to other components of the transformer, thereby further affecting the overall quality and performance of the transformer. Moreover, this situation is likely to affect the overall delivery of the transformer, causing great inconvenience and losses to both the manufacturer and the customer. Utility Model Content

[0003] In order to overcome the deficiencies of the prior art, the utility model provides a test device for detecting the magnetic shielding insulation performance of a lung lobe, which has the advantage of being able to discover magnetic shielding defects in advance.

[0004] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: a test device for detecting the insulation performance of lung lobe magnetic shielding, comprising an oil tank, the interior of the oil tank is padded with insulating pads, the lung lobe magnetic shielding products to be tested are placed on the top of the insulating pads, and the lung lobe magnetic shielding products to be tested are two groups, each group has two products, simulated electrodes are sandwiched between the lung lobe magnetic shielding products to be tested, and simulated electrodes are sandwiched between the two groups of lung lobe magnetic shielding products to be tested, the simulated electrodes are connected in parallel with the simulated electrode pressure line, and the simulated electrode pressure line extends out of the oil tank, and the lung lobe magnetic shielding products to be tested are all separately led out of the oil tank through the insulation performance monitoring lead line.

[0005] As a preferred technical solution of the present invention, the interior of the oil tank is padded with insulating pads, and the insulating pads are in two groups and are arranged in an array on the inner bottom side of the oil tank.

[0006] As a preferred technical solution of the present invention, the oil tank is sealed on four sides, and the insulating pad is placed on the inner bottom side of the oil tank.

[0007] As a preferred technical solution of the present invention, simulation electrodes are sandwiched between the magnetically shielded finished products of the pulmonary lobes to be tested, and two groups of magnetically shielded finished products of the pulmonary lobes to be tested are sandwiched between simulation electrodes in close contact.

[0008] As a preferred technical solution of the present invention, the simulation electrode is connected in parallel with the simulation electrode pressurizing line, and the simulation electrode pressurizing line extends out of the oil tank.

[0009] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0010] The utility model inserts insulating pads inside the oil tank, stacks the finished lung lobe magnetic shielding products to be tested in the manner of sandwiching a simulated electrode between two finished lung lobe magnetic shielding products to be tested, connects all the simulated electrodes in parallel with the simulated electrode pressure line, and leads out each finished lung lobe magnetic shielding product to be tested separately through the insulation performance monitoring lead-out line. When the installation is completed, oil is filled and pressurized through the simulated electrode pressure line. The insulation performance of the finished lung lobe magnetic shielding product to be tested is monitored by the insulation performance monitoring lead-out line of each finished lung lobe magnetic shielding product to be tested, so as to test the insulation performance of the finished lung lobe magnetic shielding product to be tested. Compared with traditional devices, the present device can pre-detect magnetic shielding defects before the transformer test, and can determine the insulation parameters of the working assembly of the lung lobe magnetic shielding according to the electrical parameters of the transformer. The test device is suitable for testing multiple groups of magnetic shielding, has high detection efficiency, avoids the loss of time and cost caused by rework, and reduces the factors affecting delivery time.
