Technical Field
The utility model relates to a converter transformer technical field especially relates to an extra-high voltage converter transformer is experimental with enclosing fender structure.
Background
With the development of national economy and the increasingly prominent problem of unbalanced energy distribution and power demand in China, the remote trans-regional power transmission and distribution of the western and east power transmission becomes a main strategy of a power system in China. The extra-high voltage direct current transmission project has the advantages of low transmission line loss, long-distance large-capacity transmission capacity, capability of greatly improving the utilization rate of transmission corridors, land resource saving, strong networking capacity and the like, so that the construction of an extra-high voltage direct current transmission system becomes a necessary choice for the development of the power industry in China. At present, a plurality of built or under-built ultrahigh voltage direct current transmission projects exist.
The converter transformer is a key device of extra-high voltage direct current transmission engineering, is a core device of interfaces at two ends of rectification and inversion in an alternating current transmission system and a direct current transmission system, plays a role in transmitting electric power of a transmitting end alternating current system to a rectifier or receiving electric power from an inverter and transmitting the electric power to a receiving end alternating current system, and plays an extremely important role in transmitting electric energy, isolating the alternating current system and the direct current system and the like.
However, the fire occurrence rate of the converter transformer is very high, and the converter transformer is a main fire hazard source of the converter station. Therefore, the performance of the converter transformer is improved, so that the safe operation of the converter transformer is ensured, and the method is a key and important guarantee for improving the stability and the reliability of a direct current transmission system and obtaining the power generation benefit.
In order to improve the structure and related performance parameters of the converter transformer, a simulation test of arc striking and discharging of the transformer under different short-circuit currents needs to be carried out, and parameters such as strength, temperature and bearing pressure of a transformer shell are measured. However, when a high voltage and a short-circuit large current are applied, a transformer fire may be caused by a short-circuit fault in the test process, and with the occurrence of a large explosion, parts such as a transformer bushing and a lifting seat are all blown away, oil in the transformer overflows and splashes, and the fire may be further expanded.
SUMMERY OF THE UTILITY MODEL
For reducing the horizontal splash of explosive and oil, the utility model provides an extra-high voltage converter transformer is experimental with enclosing fender structure.
The utility model provides an extra-high voltage converter transformer is experimental with enclosing fender structure which characterized in that: the enclosure structure is square, surrounds the periphery of the test platform, and consists of a protective support and a protective plate, and the protective plate is fixed on the protective support.
