Hot summer heat and the outdoor temperature are also very high, many of the cables will face a problem is too hot, and in the summer is a high incidence of electrical safety accidents.
To avoid the summer unsafe electricity caused by irreparable damage, the ZMS cable editor today to talk to you about the summer power cable use precautions, the next to take a look at.
1 Must prohibit smoking in wheat farms, oil depots, warehouses, beds, sofas, and other combustible materials, and do not drop cigarette butts and ashes in the wheat grass, power cables, and other products near to prevent ignition.
Otherwise, the consequences are unthinkable.
2 Must regularly check the cable line, and switch power.
Cable lines such as aging and broken, must be replaced promptly.
Touch the outer skin of the power cable with your hand when replacing it, if there is heat and heat and other phenomena, should also be dealt with on time.
3 Do not overload electricity, so as not to cause line overload, resulting in line equipment fever and fire.
When buying insulated power cables you should buy large-size power cables.
4 It is strictly forbidden to cover paper or cover other combustible materials on light bulbs and small suns.
It is strictly forbidden to put uncooled electric heating apparatus in place with combustible materials or put combustible materials on electric heating apparatus.
5 Before going out to work and study, you must turn off the electrical equipment, so as not to work for a long time, the power cable appears high load operation phenomenon.
However, in addition to the summer hot weather beware more attention to the thunderstorm weather.
Summer is more thunderstorm season, and many chemical enterprises frequently occur due to lightning strikes caused by mechanical and electrical, power, instrumentation, communications, metering, and electrical control system damage, resulting in equipment failure, tripping shutdown, false starts, and other accidents.
It also often causes combustible gas venting orifices to catch fire due to lightning strikes and even leads directly to accidents.
Summer is also the season of electrical accidents, in the lightning, electrical accident prevention is to focus on the following work.
1 Every year before the arrival of the thunderstorm season, in advance of all equipment, electrical, instrumentation, and other lightning protection grounding situation for a comprehensive and detailed mapping verification.
Comprehensive testing of a lightning grounding impact grounding resistance value, to ensure that the resistance value is not greater than 10 ohms, there are problems with timely rectification, so that no oversight.
2 To the key instrumentation circuit plus lightning protector, the main control room instrumentation room wall, roof, etc. ready for rain.
3 Electrically, make good temperature detection for transformers, cables, cable joints, motors, electrical components contact points, etc. to prevent over-temperature.
Make good preparation for rain and waterproofing in the substation and distribution rooms, switch stations, junction boxes, bearings, etc., and make good inspections after the rain.
The substation and distribution room, switch box, etc. should also do a good job to prevent small animals from entering.
4 The safety valve of the storage tank, emptying port, and other parts of the tank are the focus of lightning protection.
These places are vulnerable to lightning strikes, and fire must be a combination of daily inspection and regular inspection and timely rectification of existing problems.
5 Often check the grounding wire, jumper cables, and other lightning protection facilities, to ensure that not loose, and not seriously rusted.
Lightning protection grounding wire, and jumper wire in the disassembly and maintenance of pipelines, and equipment, to instantly restore to ensure normal work.
6 Check whether there is any leakage in the pipeline connection to avoid the leakage of liquefied gas from catching fire due to lightning strikes.
7 Thunderstorms are prone to cause electrical accidents, resulting in shaking or blackout of the device.
Continuously improve the emergency plan and conduct drills to ensure that power outage accidents can be handled correctly and the impact minimized.
8 In case of a thunderstorm, do self-protection measures to prevent the human body from being struck by lightning.
9 Summer weather is hot, humid, and rainy, electrical lines and facilities are less insulated and prone to electric leakage.
Non-staff should stay away from electrically charged facilities, and disconnect the power supply when moving electrical equipment.
Generally speaking, electrocution is the human body touching the charged body, the arc discharge between the charged body and the human body, and the current flows through the body into the earth or into other conductors to form a circuit phenomenon.
In general: "Do not panic, try to get rid of the power".
In case of minor electric shock, such as numbness in the hands and blackness in front of the eyes, you will recover quickly on your own.
If you experience a strong electric shock and there is no one nearby to rescue you, it is important to remain calm and start saving yourself quickly.
In the first few seconds after electrocution, people do not completely lose consciousness.
1 If you come into contact with a wire in the air, you can use your other hand to grab the wire insulation and pull it out quickly to get rid of the electric shock.
2 If the electrocution appliance is installed in a fixed position such as a wall, you can use your feet to stomp to make your body fall backward to get rid of the power.
3 Can use insulators dry wood and bamboo sticks, rubber sticks, etc. to pick open or cut off the electrocuted body of the wire socket, lamps, metal objects, and other electrically charged items.
In short, if electrocuted that will be a very urgent and dangerous thing, be sure to quickly get out of the power supply.
Summer electricity and power cable protection are related to personal safety, I hope you have paid more attention.
