Oil-discharging and nitrogen-injecting fire extinguishing apparatus of transformer

变压器排油注氮灭火装置

Abstract

本实用新型公开了一种变压器排油注氮灭火装置,氮气瓶组通过注氮回路连接变压器油箱底部,注氮回路上安装有注氮阀;可控排油管路安装有检修阀和排油阀,可控排油管路一端连接储油池,另一端通过排油管路连接在变压器油箱的上部,排油管路上安装有检修阀;多个火灾探测器、瓦斯继电器和截流阀的控制端分别通过导线连接控制装置;排油阀和注氮阀为电磁阀,其控制端由导线连接控制装置。本实用新型直接由控制装置控制排油阀和注氮阀启闭,开启迅速可靠,并可有效防止氮气的泄漏、防止灭火误动作的发生。其灭火迅速、可靠,节省了工人的劳动强度。
The utility model discloses an oil-discharging and nitrogen-injecting fire extinguishing apparatus of a transformer. A nitrogen bottle group is connected with the bottom of a transformer oil tank by a nitrogen-injecting loop which is provided with a nitrogen-injecting valve; a controllable oil discharging pipeline is provided with an overhauling valve and an oil discharging valve; one end of the controllable oil discharging pipeline is connected with an oil storing pool, and the other end of the controllable oil discharging pipeline is connected at the upper part of the transformer oil tank by the oil discharging pipeline which is provided with the overhauling valve; the control ends of a plurality of fire disaster detectors, a gas relay and a cut-off valve are respectively connected with a control device by wires; and the oil discharging valve and the nitrogen-injecting valve are electromagnetic valves, and the control ends of the oil discharging valve and the nitrogen-injecting valve are connected with the control device by wires. The oil-discharging and nitrogen-injecting fire extinguishing apparatus of the transformer controls the opening and closing of the oil discharging valve and the nitrogen-injecting valve by the control device, can be fast and reliably opened, and can effectively prevent the leakage of nitrogen, and prevent the occurrence of fire-extinguishing misoperation. The oil-discharging and nitrogen-injecting fire extinguishing apparatus can fast and reliably carry out fire extinguishment and save labor intensity of workers.
