水能導電，用直流水槍的水柱撲救帶電的電氣設備火災，對滅火人員的身體是有害的。所以，在滅火戰斗中在設備帶電的情況下，我們一般要先切斷電源，再進行撲救。但是，因生產或其他原因無法切斷電源時，就需要帶電滅火。
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.
The following is the introduction of several methods of live water fire suppression by Chongqing security company.
一，在金屬水槍噴嘴上安裝接地線
First, the grounding wire is installed on the nozzle of a metal water gun
接地線可甩截面5-10mm，長1m以上的銅絞線。接地棒可用1m以上，直徑50咖鋼管或50×50mm的角鋼，撲救人員穿戴絕緣手套和絕緣膠靴。在帶電滅火前，水槍手應將接地線的一端牢固地接在金屬水槍噴嘴上，另一端與接地棒連接，并將接地棒釘人地下05米左右，并在接地棒處倒鹽水或普通水。如果接地線與其他接地裝置連接，則要求接觸良好，持水槍時手的位置一定要放在接地線后面，選擇好與帶電體的距離，然后射水撲救。
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、穿戴絕緣手套、絕緣靴
Two. Wear insulating gloves and insulated boots
穿戴絕緣手套和絕緣靴用水滅帶電火災時，要選擇最有經驗的水槍手，盡可能擴大水槍噴嘴至帶電體之間的距離，要采取有效措施防止水滴流進手套和膠靴，站在絕緣板上，面向火源，以點射的方法，使水滴落在火源上。在一般情況下，最好不要使用充實水柱直接射向火源，以防止發生觸電危險
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、穿戴均壓服
Three. Wear all wear and wear
目前使用的均壓服有兩種：一種是棉纖維或動物纖維與紫銅絲拼捻的經緯交織布制成的，另一種是用棉布經化學鍍銅或鍍銀制成的。這兩種均壓服在棉紗或棉布里面，部含有很大成分的金屬導體。用這種材料制成的均壓服包括：帽子、手套、衣服、襪子、鞋面等，而鞋底則用導電橡膠制成。在穿戴均壓服時，一定要把衣服、手套、襪子和膠鞋之間的按扣扣好，使其相互之間的銅線擰在一起，形成一條良好的接地線，然后根據電壓的大小選好射水距離，利用金屬水槍射水撲救。
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、采用噴霧水流。
Four. The spray flow is used.
選用噴霧水槍或在直流水槍的槍口上安裝一個雙級離心式噴霧頭，即成為雙級離心式噴霧水槍。這種水槍射出的水流，霧化程度好，幾乎是不導電的。實驗證明，當水槍的噴嘴距離127千伏帶電體5米，并在每平方厘米7千克水壓下進行帶電滅火時，沒有漏泄水流，其射程可達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.
用這種噴霧水槍進行帶電滅火時，水槍可以不接地線，直接帶電滅火。但要根據電壓大小選好與帶電體的安全距離，消防車泵壓力應保持05-0.7MDa，并在水槍噴出的霧狀水正常后，才能射向帶電體撲救火災。
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、帶電滅火具體措施
Five. Concrete measures for charged fire extinguishing
1、確定帶電設備、線路的電壓。
1. Determine the voltage of the electrified equipment and the line.
火場指揮員應與該單位的負責人或電工取得聯系，弄清起火設備、線路的電壓，確定與之應保持的最小安全距離，然后再組織滅火。對電壓在250V以下的電源，可穿戴絕緣手套，用絕緣電剪將電線剪斷。
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.
經查閱資料，人體與帶電設備、線路必須保持的最小安全距離為：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、使用氣體或千粉滅火器滅火。
2. Fire extinguishers with gas or powder fire extinguisher.
對規模、范圍較小的帶電設備或線路火災，可使用二氧化碳、1211、FM200或干粉滅火器直接噴射滅火。鑒于火場1青況復雜，為確保安全，人體和滅火器必須遠離帶電設備和線路，以防跨步電壓或達到放電間隙而導致觸電傷亡。
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、啟用固定滅火裝置滅火。
3, put out the fire extinguishing device with fixed fire extinguishing device.
電力設施通常安裝的固定滅火裝置主要有以下三種：蒸汽滅火裝置；氣體滅火裝置；水噴霧滅火裝置。消防隊到達現場后，火場指揮員應詢問并檢查是否啟用了固定滅火裝置，如沒啟用，應酌情啟用。
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、使用噴霧水槍帶電滅火。
4, the use of spray water gun fire extinguishing.
將消防車泵壓調到0.7MPa以上，待噴霧水槍射出的水流成霧化狀態后，再對準帶電目標滅火。
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、使用直流水槍帶電滅火。
5, the use of direct current water gun fire extinguishing.
在沒有帶電滅火設備和噴霧水槍的情況下，用直流水槍噴射充實水柱，使用自來水也可以應急撲滅220千伏以內的高壓帶電設備或線路火災。
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.
具體方法是：使用大口徑水槍，站在距帶電物體7米以外的地方，水槍手穿絕緣靴，戴絕緣手套，運用點射進行遠距離射水滅火或使水流呈拋物線狀落于火點。
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、滅火注意事項
Six. Precautions for fire extinguishing
1、用泡沫帶電滅火需注意，在沒有形成泡沫時不能沖擊帶電體，泡沫流淌區域不能有人，以防泄漏電流傷人。
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、水槍手最好戴絕緣手套，穿絕緣靴、均壓服等安全防護裝具，其他人員不得接近正在滅火的消防員、燃燒區和積水區。
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、水槍噴嘴、滅火器和人體必須與高壓帶電設備或線路保持相應的安全距離。
3, water gun nozzles, fire extinguishers and human body must be kept at a safe distance from high-voltage live equipment or lines.
4、撲救架空高壓帶電設備或線路火災
4. Extinguishing overhead high voltage electrified equipment or line fire
