Background
The insulating sleeve is a weak link of the converter transformer safety, and the explosion and fire accident of the sleeve accounts for a large proportion of the fire accident of the transformer. The sleeve explosion ignition is mainly characterized in that the sleeve is operated under a long-term ultrahigh voltage due to internal hidden dangers such as unreasonable structural design, manufacturing process defects and the like, the hidden dangers are gradually exposed and continuously enlarged, and finally oil injection ignition caused by sleeve explosion is caused. And secondly, under the influence of environment and climate, the sealing performance of the sleeve is reduced or the surface is polluted, so that the insulation is reduced to trigger the explosion of the insulation breakdown sleeve to cause fire. In addition, the occurrence of a bushing accident caused by improper installation or overhaul and the like can cause the transformer body to be ignited to destroy the internal structure of the transformer body once the bushing is exploded to be ignited and directly endanger the safety of the transformer body, thereby causing great economic loss.
The special equipment such as a converter transformer, a converter valve and the like of the converter station not only has high manufacturing cost, but also has unique equipment arrangement, and has obvious defects if the equipment is completely designed according to the current fire-fighting design specification. For example, a wall bushing of the converter transformer penetrates through a firewall to be connected with the converter valve, once the transformer or the wall bushing explodes and fires, the safety of the converter valve is threatened, and if the network side bushing of the converter transformer explodes and fires and cannot be put out in time, the transformer body fires, so that the bushing of the converter transformer is provided with a fixed water spray protection measure. However, according to the regulation of ' water spray fire extinguishing system design specification ' item 3.2.5.2, the water spray at the top of the protection transformer should not be directly sprayed to the high-voltage bushing ', the bushing is not in the protection range of the water spray system, in practical application, after a bushing on the net side of a converter transformer of a converter station explodes and fires, although the water spray system timely acts and the water pressure of water is sufficient, the transformer body is effectively protected, the bushing still continuously burns, and a fire fighter cannot only climb up the transformer to manually extinguish the fire. Therefore, the fire fighting mode of the converter transformer bushing of the existing converter station is very not intelligent.
