保安教您如何用水扑救带电设施

来源:http://www.cqzhongtebao.com  发布时间:2018-04-19
水能导电,用直流水枪的水柱扑救带电的电气设备火灾,对灭火人员的身体是有害的。所以,在灭火战斗中在设备带电的情况下,我们一般要先切断电源,再进行扑救。但是,因生产或其他原因无法切断电源时,就需要带电灭火。
It is harmful to the body of the firefighters that the water can conduct electricity and the water column of the direct current water gun can extinguish the fire caused by the electrified electrical equipment. Therefore, in the case of fire fighting, when equipment is electrified, we usually need to cut off the power supply before fighting. However, due to production or other reasons can not cut off the power supply, you need live fire.
下面由重庆保安公司为您介绍几种用水带电灭火的方法
The following is the introduction of several methods of live water fire suppression by Chongqing security company.
一,在金属水枪喷嘴上安装接地线
First, the grounding wire is installed on the nozzle of a metal water gun
接地线可甩截面5-10mm,长1m以上的铜绞线。接地棒可用1m以上,直径50咖钢管或50×50mm的角钢,扑救人员穿戴绝缘手套和绝缘胶靴。在带电灭火前,水枪手应将接地线的一端牢固地接在金属水枪喷嘴上,另一端与接地棒连接,并将接地棒钉人地下05米左右,并在接地棒处倒盐水或普通水。如果接地线与其他接地装置连接,则要求接触良好,持水枪时手的位置一定要放在接地线后面,选择好与带电体的距离,然后射水扑救。
The grounding wire can be twisted 5-10mm, and the length of 1m is longer than that of the copper wire. The grounding rod can be used for more than 1m, diameter of 50 Ka steel or 50 x 50mm angle, the firefighters wear insulating gloves and insulating rubber boots. Before the fire extinguishing, the shooter should firmly connect one end of the grounding wire to the metal gun nozzle, the other end is connected with the grounding rod, and the earthing stick is about 05 meters underground, and the saltwater or ordinary water is placed at the grounding rod. If the grounding wire is connected to other grounding devices, it requires good contact. When the water gun is held, the position of the hand must be placed behind the grounding wire, the distance from the charged body is chosen, and then the water is saved.
二、穿戴绝缘手套、绝缘靴
Two. Wear insulating gloves and insulated boots
穿戴绝缘手套和绝缘靴用水灭带电火灾时,要选择最有经验的水枪手,尽可能扩大水枪喷嘴至带电体之间的距离,要采取有效措施防止水滴流进手套和胶靴,站在绝缘板上,面向火源,以点射的方法,使水滴落在火源上。在一般情况下,最好不要使用充实水柱直接射向火源,以防止发生触电危险
When wearing insulating gloves and insulation boots, the most experienced shooters should be selected to expand the distance between the nozzle and the charged body as far as possible. Effective measures should be taken to prevent water droplets from flowing into the gloves and rubber boots, standing on the insulating board, facing the fire source, and dropping the water droplets on the fire source. In general, it is best not to use a full water column to shoot directly into the fire source to prevent electric shock.
三、穿戴均压服
Three. Wear all wear and wear
目前使用的均压服有两种:一种是棉纤维或动物纤维与紫铜丝拼捻的经纬交织布制成的,另一种是用棉布经化学镀铜或镀银制成的。这两种均压服在棉纱或棉布里面,部含有很大成分的金属导体。用这种材料制成的均压服包括:帽子、手套、衣服、袜子、鞋面等,而鞋底则用导电橡胶制成。在穿戴均压服时,一定要把衣服、手套、袜子和胶鞋之间的按扣扣好,使其相互之间的铜线拧在一起,形成一条良好的接地线,然后根据电压的大小选好射水距离,利用金属水枪射水扑救。

There are two kinds of uniform clothing used at present: one is made of cotton fiber or animal fiber and weft interwoven fabric twisted with purple copper wire. The other is made of cotton or silver plated or silver plated. These two kinds of pressure are pressed in cotton or cotton cloth, and they contain large metal conductors. The uniform clothing made of this material includes: hat, gloves, clothes, socks, shoe upper and so on, while the sole is made of conductive rubber. When wearing uniform clothing, it is necessary to buckle the buttons between clothes, gloves, socks and rubber shoes, make the copper wire of each other together, form a good grounding wire, and then select the water distance according to the size of the voltage, and use a metal water gun to save water.
四、采用喷雾水流。
Four. The spray flow is used.
选用喷雾水枪或在直流水枪的枪口上安装一个双级离心式喷雾头,即成为双级离心式喷雾水枪。这种水枪射出的水流,雾化程度好,几乎是不导电的。实验证明,当水枪的喷嘴距离127千伏带电体5米,并在每平方厘米7千克水压下进行带电灭火时,没有漏泄水流,其射程可达8-9米。
A two-stage centrifugal spray head is installed on the muzzle of a water gun or a gun at the same time, that is to say, it is a two stage centrifugal spray gun. The water jet produced by this water gun is atomized and is almost non-conductive. The experiment shows that when the nozzle of the water gun is 5 meters from 127 thousand volt charged body and is charged under the water pressure of 7 kilograms per square centimeter, there is no leakage flow, and the range of the water gun is up to 8-9 meters.
用这种喷雾水枪进行带电灭火时,水枪可以不接地线,直接带电灭火。但要根据电压大小选好与带电体的安全距离,消防车泵压力应保持05-0.7MDa,并在水枪喷出的雾状水正常后,才能射向带电体扑救火灾。
When using this spray gun to extinguish a live fire, the water gun can not directly connect to the ground, and fire directly. But to select the safe distance from the charged body according to the size of the voltage, the pump pressure of the fire truck should be kept 05-0.7MDa, and the fire can be shot to the charged body after the water spray of the water gun is normal.
五、带电灭火具体措施
Five. Concrete measures for charged fire extinguishing
1、确定带电设备、线路的电压。
1. Determine the voltage of the electrified equipment and the line.
火场指挥员应与该单位的负责人或电工取得联系,弄清起火设备、线路的电压,确定与之应保持的最小安全距离,然后再组织灭火。对电压在250V以下的电源,可穿戴绝缘手套,用绝缘电剪将电线剪断。
The commander of the fire field shall contact the person in charge or the electrician of the unit, find out the voltage of the fire equipment and line, determine the minimum safe distance to keep it, and then organize the fire extinguishing. The power supply voltage below 250V, wearable insulating gloves, insulated electric wires will be cut off.
经查阅资料,人体与带电设备、线路必须保持的最小安全距离为:110千伏大干1米;220千伏大于1米;330千伏大于4米。
By consulting the data, the minimum safe distance between the human body and the electrified equipment and the line must be kept: 110 thousand volts 1 meters large, 220 thousand volts more than 1 meters, and 330 thousand volts greater than 4 meters.
2、使用气体或千粉灭火器灭火。
2. Fire extinguishers with gas or powder fire extinguisher.
对规模、范围较小的带电设备或线路火灾,可使用二氧化碳、1211、FM200或干粉灭火器直接喷射灭火。鉴于火场1青况复杂,为确保安全,人体和灭火器必须远离带电设备和线路,以防跨步电压或达到放电间隙而导致触电伤亡。
For small scale or less charged live equipment or line fires, carbon dioxide, 1211, FM200 or dry powder extinguishers can be used for direct fire suppression. In view of the complex 1 green conditions of the fire field, in order to ensure safety, the human body and the fire extinguisher must be far away from the electrified equipment and line to prevent the striding voltage or the discharge gap.
3、启用固定灭火装置灭火。
3, put out the fire extinguishing device with fixed fire extinguishing device.
电力设施通常安装的固定灭火装置主要有以下三种:蒸汽灭火装置;气体灭火装置;水喷雾灭火装置。消防队到达现场后,火场指挥员应询问并检查是否启用了固定灭火装置,如没启用,应酌情启用。
There are mainly three kinds of fixed fire extinguishing devices installed in electric power facilities: steam fire extinguishing device, gas fire extinguishing device, water spray fire extinguishing device. After the fire brigade arrives at the scene, the commander of the fire field should inquire and check whether the fixed fire extinguishing device has been enabled. If it is not enabled, it should be activated as appropriate.
4、使用喷雾水枪带电灭火。
4, the use of spray water gun fire extinguishing.
将消防车泵压调到0.7MPa以上,待喷雾水枪射出的水流成雾化状态后,再对准带电目标灭火。
The pump of the fire engine is adjusted to more than 0.7MPa. After the water flowing from the spray gun is atomized, the fire is fired at the charged target.
5、使用直流水枪带电灭火。
5, the use of direct current water gun fire extinguishing.
在没有带电灭火设备和喷雾水枪的情况下,用直流水枪喷射充实水柱,使用自来水也可以应急扑灭220千伏以内的高压带电设备或线路火灾。
In the absence of charged fire extinguishing equipment and spray water guns, a direct current water gun is injected to fill the water column, and the use of tap water can also extinguish the fire of high voltage electrified equipment or line within 220 thousand volts.
具体方法是:使用大口径水枪,站在距带电物体7米以外的地方,水枪手穿绝缘靴,戴绝缘手套,运用点射进行远距离射水灭火或使水流呈抛物线状落于火点。
The specific methods are: using large caliber water guns, standing outside 7 meters away from the charged objects, the shooters wear insulating boots and insulated gloves.
六、灭火注意事项
Six. Precautions for fire extinguishing
1、用泡沫带电灭火需注意,在没有形成泡沫时不能冲击带电体,泡沫流淌区域不能有人,以防泄漏电流伤人。
1, pay attention to the use of foam charged fire. When the foam is not formed, the charged body can not be impacted, and no person can be found in the foam flowing area, so as to prevent the leakage current from hurting people.
2、水枪手最好戴绝缘手套,穿绝缘靴、均压服等安全防护装具,其他人员不得接近正在灭火的消防员、燃烧区和积水区。
2, the shooters should wear insulated gloves, insulated boots, uniform clothing and other safety protective equipment, and other personnel should not be close to fire extinguisher, burning area and water accumulation area.
3、水枪喷嘴、灭火器和人体必须与高压带电设备或线路保持相应的安全距离。
3, water gun nozzles, fire extinguishers and human body must be kept at a safe distance from high-voltage live equipment or lines.
4、扑救架空高压带电设备或线路火灾
4. Extinguishing overhead high voltage electrified equipment or line fire
