Description
Technical Field
The utility model relates to a transformer antidetonation auxiliary stay structure belongs to transformer technical field.
Background
The transformer is one of the most complex and most core electrical devices in the structural style of the power transmission and transformation system. The transformer generally comprises an oil tank, a coil, an iron core, a sleeve, an oil storage cabinet, a cooling device and the like, and the structural form of the transformer is more and more complex along with the improvement of the voltage grade and the transformation capacity. Many areas of China are in earthquake high-rise areas, direct economic loss caused by earthquakes is hundreds of millions, and indirect economic loss cannot be estimated. According to relevant literature data, the damage of the transformer in the earthquake is shown to be various, and the recovery difficulty after the disaster is very high, so that the improvement of the earthquake resistance of the transformer is an important link for improving the earthquake resistance safety of the power system. Therefore, in recent years, the seismic performance of transformers has been increasingly studied, and the requirement for seismic design of large transformers has been increasing.

Detailed Description
The technical solution of the present invention will be further described in detail with reference to the accompanying drawings and embodiments.
The utility model provides a transformer antidetonation auxiliary stay structure, contains oil tank 1, ground 2, dolly 3, track 4, auxiliary stay device 5, auxiliary stay device ground 6 and steel sheet 7, dolly 3 has two, fixes through the accordant connection of two dollies 3 and track 4 between the bottom of the case of oil tank 1 and the ground 2, and 6 equipartitions of auxiliary stay device ground set up on ground 2, and steel sheet 7 is pre-buried in auxiliary stay device ground 6, and auxiliary stay device 5 supports the bottom of the case that sets up at oil tank 1, through 7 fixed connection of steel sheet in welding and the auxiliary stay device ground 6.
The height of the auxiliary supporting device 5 is matched with the distance between the bottom of the oil tank 1 and the foundation 2.
Six auxiliary supporting devices 5 and six steel plates 7 are arranged at the bottom of the oil tank 1 symmetrically.
In practical application, the tank bottom and the foundation of the transformer oil tank are rigidly fixed under the common condition of a large transformer. Referring to fig. 1, the fixing mode of the transformer is special, the bottom of the transformer oil tank has a certain height from the ground plane, and the fixing mode is the interaction of a trolley 3 and a rail 4. The centre-to-centre spacing of the rails 4 is a fixed distance of 1505mm, while the transformer tank base is wider and has a greater overturning moment relative to the rail gauge of 1505 mm. In addition, the distance H between the gravity center of the transformer and the foundation is large, and displacement earthquake damage and overturning earthquake damage are easy to occur. The structure has great defects on the anti-seismic effect, so the additional auxiliary supporting device 5 well enhances the anti-overturning moment and the anti-seismic performance of the transformer. As shown in fig. 1 and fig. 2, the foundation 6 of the auxiliary supporting device is uniformly distributed on the foundation, and steel plates 7 are embedded on the foundation; after the transformer is in place, the auxiliary supporting device 5 is installed and welded and fixed on the auxiliary supporting device foundation 6. And through earthquake simulation calculation comparison, the structure has obvious earthquake resisting effect and obvious damping effect.
