Description

Transformer sealing washer elasticity performance detects analogue means Technical Field The utility model relates to the field of performance detection of a transformer sealing ring, in particular to a device for detecting and simulating the elastic performance of the transformer sealing ring. Background The sealing ring is an insulating elastic element for sealing, dampproofing and dust prevention of the transformer, and the performance of the sealing ring is related to the reliability and stability of the operation of the transformer equipment. In addition, in the transformer assembly process, a fastener between a related component of the transformer and the oil tank wall is required to be fastened according to the elastic quantity of the sealing ring, so that the sealing effect of the oil tank wall is determined. After the transformer is put into operation, the elasticity of the sealing ring is required to keep long-term tightness due to large temperature change in the transformer, so that the safe operation of a transformer product is ensured, the oil leakage and other problems of the transformer can occur if the long-term elasticity of the sealing ring is insufficient, and even the operation failure of the transformer occurs when the long-term elasticity of the sealing ring is serious. In the prior art, the sealing ring is usually an outsourcing finished product, and the finished product is generally responsible for detection of appearance quality, size and the like of the rubber ring by a detector after entering a factory, but the prior art lacks of long-term simulation detection of the elastic performance of the sealing ring, especially the detection of the long-term elastic performance of the sealing ring under certain pressure tolerance, so the prior art cannot effectively judge the long-term tolerance condition of the elastic performance of the sealing ring, and certain hidden danger is brought to the long-term operation of a transformer product. In the prior art, mainly, seal detection is performed on related components of a transformer to judge the reliability of long-term operation of the related components of the transformer, for example, CN104198125B discloses a seal monitoring method for simulating the seal condition of a transformer bushing, which is provided with a device for simulating the seal condition of the transformer bushing, and is used for filling oil into the device for sealing, then filling SF 6 gas into the device for detecting the seal condition after vacuumizing, and the device is used for simulating the poor seal condition and the internal water inflow condition of the transformer bushing through the seal treatment of an oil filling port and water dripping into the device. In addition, some detection devices specific to the elastic performance of the elastic element are also presented in the prior art, for example, CN221959712U discloses an elastic detection device of an elastic gasket, which can measure and obtain an elastic curve of the elastic gasket when compressed. However, since the transformer seal ring is usually installed at each installation opening on the oil tank, and the dimensions are required to be matched with related components, the same oil tank is usually required to use seal rings with various dimensions, and the device cannot be suitable for the simulation detection of the transformer seal ring to obtain the long-term elastic performance of the seal ring under a certain pressure.
