The utility model relates to a butterfly valve structure for transformer fire protection, which comprises an upper part of an oil discharge pipe, a lower part of an oil discharge pipe and a butterfly valve installed between the two parts. The butterfly valve comprises a valve body, a valve plate and a rotating shaft. The butterfly valve connects the oil discharge weight component, the oil discharge weight component is arranged on the oil discharge weight support mechanism, and the oil discharge weight component package. The butterfly valve rotating shaft passes through the installation disk and is successively connected with a fan-shaped block and a connecting rod of a heavy hammer. The oil discharge heavy hammer supporting mechanism comprises a support body. The upper end and the inner side of the support body are provided with a bullet pin. The bullet pin at the upper end of the support body is provided with a lever arm, and one end of the lever arm is a connecting rod supporting block. The other end of the lever arm is buckled with the hook plate, and the hook plate is arranged on a mounting plate through the hook plate shaft. The outer side of the mounting plate is fixed with an electromagnet, and the mounting plate has a push rod pushed by the electromagnet to exert force on the hook plate. The installation disk increases the contact area, enhances the fastness of the butterfly valve and greatly enhances the opening efficiency of the butterfly valve.

技术介绍
变压器充氮灭火装置是以冷却燃烧介质,减少燃烧面供氧两种物理原理进行快速灭火的变压器专用灭火装置。它的灭火机理完全基于重质油品的燃烧原理和变压器的火灾特征之上。装置本身不带任何冷却剂而只是提供一种必要的手段促使(液态)燃烧介质中占绝大多数(容积)的低温液体去吸收燃烧液面高温液体中的热能,从而达到降温灭火的目的。处在固定容器内的液体被加热时,热能首先被靠近热源的液体所吸收,被加热的液体受热后体积膨胀、密度降低,在浮力的作用下上升至液面,这就是自然对流原理。如果没有外力作用,高温液体总是向上运动至液面,低温液体总是在下,即使油面起火燃烧时,这种状态也不会改变。该装置在自动运行状态下,以三侧开关、重瓦斯信号及靠近着火点的温度探测器三个信号逻辑‘与’作为判别火灾发生的启动信号,充氮灭火装置在接到火灾信号后,利用连接在变压器与装置之间的排油管道立即从油箱顶部排出部分热油,排出顶部部分热油的目的,首先是充分释压,切断油枕补油通道(由连接在气体继电器与储油箱之间的断流阀执行),制止油流 ...
