Description

Converter transformer valve hall firewall with multiple purposes Technical Field The application relates to a converter transformer valve hall, in particular to a firewall of the converter transformer valve hall. Background The converter transformer is oil-containing electrical equipment and is arranged on the side surface of a valve hall building, and under the condition of equipment failure, the internal cooling oil is easy to generate fire. In order to prevent the fire disaster of the electrical equipment from affecting the safety of the valve hall building, the outer wall of the valve hall building, which is close to one side of the converter transformer equipment, is made into a firewall, namely a firewall of the valve hall of the converter station, which is a nonflammable wall body arranged between the valve hall building and the converter transformer equipment, and cast-in-situ reinforced concrete is generally adopted, and the main function is to prevent the converter transformer equipment from preventing the fire disaster from affecting the safety of the valve hall building when the fire disaster occurs. The following problems occur in the actual construction engineering: (1) Because the length of the firewall is not smaller than the arrangement length of the converter transformer, the cast-in-situ firewall is too long, and can generate internal stress of the wall body when concrete is solidified and the temperature is raised and lowered, so that cracks appear on the surface of the wall body, and the durability of the wall body is affected. (2) Besides the function of meeting the fire protection, the wall body also provides the space positions for arranging equipment such as fire equipment pipelines, fire nozzles and the like. The fire wall structure should ensure that the fire does not directly affect the fire-fighting pipeline when a fire disaster occurs, and also provide a personnel inspection channel for schedule maintenance of fire-fighting equipment, and the simple wall body cannot meet the use functions. In order to solve the problems that the firewall wall is overlong and the fireproof performance is not affected in the prior art, a post-pouring belt is usually arranged or micro-expansion concrete is adopted to counteract shrinkage deformation generated in the concrete solidification process. And the temperature stress is resisted by enlarging the reinforcement of the wall body. The engineering converter transformer is oil-containing electrical equipment, and electrical equipment fire disasters are easy to occur when faults occur. Typically, fire protection systems are disposed around the perimeter of the equipment, and in the event of equipment deflagration, damage to the fire protection system by the deflagration impact may occur. Accordingly, in addition to the fire protection system around the equipment, fire protection equipment with a longer range is disposed at a position far from the equipment. However, the construction period of the wall body is prolonged due to the fact that the post-pouring belts are arranged, and color difference is generated on the wall surface due to the difference of post-pouring concrete materials, so that the attractive effect is affected. And the post-cast strip and the micro-expansion concrete are arranged to counteract shrinkage deformation generated in the concrete solidification process, so that the temperature stress generated by the overlong wall body under the condition of temperature difference can not be reduced. Likewise, the pipeline is buried underground using a remote ground arrangement or a remote pylon arrangement. The occupied area is large, the underground pipeline is not easy to overhaul, and the site layout and equipment transportation are affected. Therefore, there is a great need in the art for a firewall architecture that satisfies the functional needs and addresses the shortcomings of existing firewalls. Disclosure of Invention The application aims to provide a firewall structure which meets the functional requirement and solves the defects of the existing firewall. The application discloses a firewall structure of a converter transformer valve hall with multiple purposes, which comprises a flat wall body, deformation joints and a fire-fighting equipment platform, wherein: The flat plate wall body comprises a transverse wall body for replacing the outer wall of the valve hall and a longitudinal wall body for separating a plurality of converter transformers, and the transverse wall body and the longitudinal wall body are further divided into a fire facing side and a fire backing side according to a fire scene; the deformation joint is configured at the junction of the transverse wall body and the longitudinal wall body and is configured as a T shape, and the inside of the deformation joint is filled with refractory materials; The fire-fighting equipment platform is arranged at the top end of the fire-facing side of the transverse wall
