Description
Technical Field
The utility model relates to a converter station converter transformer valve side sleeve pipe shutoff technical field, concretely relates to flexible block structure of converter transformer room valve side sleeve pipe hole.
Background
The converter transformer sleeve is designed to be installed through a wall for a closed building for placing a converter valve, and a fireproof and explosion-proof structure is required to be arranged between the converter transformer sleeve and a fireproof wall when the converter transformer sleeve is installed, so that fireproof and explosion-proof requirements are met. Because the oil is injected into the converter transformer bushing after the valve hall is plugged and installed, the bushing becomes heavy after the oil is injected, and sinks by about 2-3 mm, so that gaps appear at the upper part of the small plug, and the fireproof performance and the sealing performance are affected. The current conversion becomes sleeve pipe and can appear vibrating in service, and the vibration range can lead to the gap to appear in the original closely knit aluminium silicate fiber blanket of packing of little shutoff position after long-term operation vibration compression, can influence fire behavior and leakproofness equally. The blocking structure of each junction in the fire-proof and explosion-proof structure needs to achieve good anti-explosion, fire-proof, smoke-proof and waterproof effects so as to meet the requirements of daily operation and fire.
In the explosion-proof and fire-proof structure for installing the converter transformer sleeve of the converter station, a flexible blocking structure is adopted at the joint of the converter transformer sleeve and the explosion-proof and fire-proof structure. In the prior art, a simple plugging structure is only adopted at the joint of the converter transformer sleeve and the explosion-proof and fire-proof mechanism, the sealing performance of plugging is unsatisfactory due to the vibration of the sleeve in operation, and once a fire is exploded, the weak point at the plugging part becomes a main breakthrough opening for spreading the fire, so that the overall explosion-proof and fire-proof performance is influenced, and potential safety hazards exist.
For example, in the prior art, a valve side sleeve blocking fireproof and explosion-proof structure of a converter transformer of a converter station with application number 201910441087.9 is disclosed, which comprises a fireproof blocking plate and a converter transformer sleeve mounting hole, wherein a converter transformer sleeve is mounted in the converter transformer sleeve mounting hole, and an aluminum silicate needle-punched blanket layer is filled between the wall of the converter transformer sleeve mounting hole and the outer tube wall of the converter transformer sleeve; the fireproof plugging plate comprises a first metal surface structure rock wool composite plate, a second metal surface structure rock wool composite plate and a non-magnetic-conductive stainless steel impact-resistant plate, wherein an aluminum silicate needling blanket layer is arranged between the hole wall of the installation hole part of the converter transformer sleeve arranged on the first metal surface structure rock wool composite plate and the second metal surface structure rock wool composite plate and the outer wall of the converter transformer sleeve. Although the fire-proof and explosion-proof effect has been played to a certain extent in above-mentioned patent, but carry out sealing connection only through ceramic silicon rubber sealing sleeve between the sheathed tube outer wall of current conversion transformer and the fire prevention shutoff board side surface, with fire prevention shutoff board, aluminium silicate acupuncture blanket layer, the sheathed tube outer wall of current conversion transformer carries out integrative sealing, sealing performance is poor, sealing strength is low, and the linking department of current conversion transformer sleeve pipe and fire prevention shutoff board only carries out the interval through a monoblock aluminium silicate acupuncture blanket layer, fire behavior is poor, lead to holistic fire prevention and explosion-proof performance to reduce, in the conflagration of transformer, the high temperature of production can make the stainless steel panel appear very big deformation, lead to original sealed junction to warp or break away from, make fireworks scurry out, increase the potential safety hazard.
