Description
Technical Field
The invention belongs to the field of fire safety of power transmission and transformation equipment in the power industry, and particularly belongs to a fixed type fireproof and anti-explosion blocking structure for protecting a high-end valve hall of a convertor station.
Background
The converter station is the most important node of the direct current transmission line, and the key of ensuring the safe and stable operation of the converter station is direct current transmission. Converter valves and transformers are again the most important equipment in a converter station. The converter valve is connected with the converter transformer through a valve side sleeve, however, the converter transformer is used as a main noise source in the converter station, and a corresponding noise reduction scheme is required to be adopted to reduce the factory boundary noise of the converter station, so that an environment-friendly power grid is realized. The sound insulation cover (Box-in) is widely applied to noise reduction engineering of the current converter transformer due to obvious noise reduction effect, however, when the converter transformer is in a fire due to failure, the internal pressure of the Box-in is increased instantly as a closed device, the converter transformer may explode, and equipment in a valve hall connected with the converter transformer is damaged irreversibly, so that huge economic loss is caused. Therefore, necessary fire protection guarantee measures are added on the premise of guaranteeing the noise reduction and sound insulation performance of the Box-in device under the condition that the normal operation of equipment in the converter station is not influenced, so that the equipment in a valve hall is protected from being influenced by emergency when a converter transformer is in a fire disaster or even the converter transformer explodes, and the economic loss caused by the fault is reduced to the maximum extent.
At present, aiming at the protection of equipment in a valve hall of a converter station, the conventional method in the converter station adopts a paloc rock wool board, and the method is mainly characterized in that: inhale sound, dampproofing, fire-retardant, nevertheless when converter transformer explodes, it can't guarantee that valve hall internal equipment does not receive the explosion and influences, consequently, need to develop an antiknock structure of protection converter valve urgently, and under the emergency, the separation disaster spreads, ensures that barrier layer both ends equipment is relatively independent, guarantees the operation security of converter station.
CN2018214193658 discloses a converter transformer valve hall side firewall plugging explosion-proof structure, which realizes valve hall entrance plugging reinforcement through the structural form of a sliding door, but because the actual situation of the current domestic converter station is relatively complex, the adopted sleeve distribution form of the converter transformer has multiple forms of vertical arrangement, left-right arrangement, diagonal arrangement and the like, so that the applicability of the sliding door structure is limited, and certain requirements are also provided for firewall spaces on two sides of the valve hall entrance. Meanwhile, because the distance between the high-end converter transformer adopted at present and a valve hall wall is very short when the high-end converter transformer is in a falling position, the actual construction space of the beam-slab structure anti-explosion plugging taking the H-shaped steel as the framework is very narrow and even has no construction feasibility, and therefore the anti-explosion plugging structure which is more suitable for the research of the high-end converter transformer by combining with the actual working condition is needed.
Disclosure of Invention
The invention aims to provide a fixed fireproof and anti-explosion blocking structure for protecting equipment in a valve hall from being influenced by emergency situations and reducing economic loss caused by faults to the maximum extent for a converter station, so as to overcome the defect that the equipment in the valve hall cannot be ensured not to be influenced by explosion when a converter transformer of the current converter station explodes.
In order to achieve the purpose, the invention adopts the technical scheme that:
a fixed fireproof and anti-explosion blocking structure for protecting a high-end valve hall of a convertor station,
the converter station comprises a converter valve and a converter transformer, wherein the converter valve is positioned in a high-end valve hall and is connected with the converter transformer outside the valve hall through a valve side sleeve, and the converter station is characterized in that: and a fixed fireproof anti-explosion door is added at the converter transformer side of the fireproof plugging of the original high-end valve hall for plugging at the high-end valve hall cave mouth where the converter transformer is connected with the converter valve.
Fixed fire prevention antiknock door adopt and use H shaped steel as the skeleton girder steel, use stainless steel square pipe laminating corrosion resistant plate as fire prevention antiknock door panel, and it has fire-resistant material to fill in the middle of the stainless steel square pipe.
And the fixed fireproof anti-explosion door plugged anti-explosion door panels in each interval of the converter transformer are made into a plurality of blocks, and each block is connected to the framework steel beam by using stainless steel bolts.
The H-shaped framework steel beam is Q235B carbon steel and has the specification of HN294 200 9 14 (mm);
the stainless square tube is made of austenitic 304 stainless steel, and the specification is 80 × 6(mm) and 80 × 60 × 6 (mm);
the stainless steel plate is austenitic 304 stainless steel with the thickness of 3 mm;
the fireproof filling material is an aluminum silicate needled blanket with the thickness of 80mm, and refractory mortar is filled between the aluminum silicate needled blanket and the stainless steel square tube.
The invention has the beneficial effects that: the fixed fireproof and anti-explosion blocking structure is additionally arranged outside the fireproof blocking of the original high-end valve hall of the converter station, and has the effects that when a converter transformer is ignited to generate explosion, the fireproof and anti-explosion blocking structure can not only physically isolate the side of the converter transformer from the side of the valve hall, but also prevent the fire at the side of the converter transformer from spreading to the side of the valve hall to cause immeasurable loss, and can resist the shock waves generated by the side of the converter transformer to the side of the valve hall when the transformer is exploded to protect important equipment in the valve hall from the influence of explosion overpressure.
In addition, considering the convenience of operation and maintenance, the fixed type fireproof anti-explosion door panel for plugging is made into a plurality of blocks, so that the fixed type fireproof anti-explosion door is convenient to disassemble and assemble.
