Common sense courseware of ship electrical safety in summer

1. Common sense of safe electricity use in summer

The peak of electricity consumption in summer is coming. With the improvement of living standards and the increase of household appliances, faults caused by overload electricity use frequently occur. In order to ensure the safety of electricity consumption in summer, users should calculate their total electricity consumption before the summer comes and compare it with the maximum rated current of electric meters and power lines. If it is not enough, they should report to the power supply department in time to increase the capacity of the meter. It is best not to start high-power appliances such as air conditioners and microwave ovens at the same time, otherwise the instantaneous surge current will be too large, which will burn out the electric meter.

In areas with complex lines, the power supply should be installed by professionals, otherwise it will cause serious consequences. Copper wire and aluminum wire are prohibited. Replace the fuse; Signal transmission lines cannot be used instead of power lines; Medical leucorrhea and transparent belt cannot be used instead of insulating black belt.

Residents should actively guard against human invasion of lightning in thunderstorm season. There are four ways for induction lightning to invade: power lines, telephone lines, cable TV lines, external walls of houses or pillars. Therefore, it is very important to check the grounding wire regularly. Because if lightning strikes, the current generated by lightning will be led to the ground along the grounding lead to avoid electrical damage.

Many families keep the TV on standby or off after watching it. In fact, from the perspective of electricity safety, these two practices are unsafe. After watching TV, you should unplug the power cord while turning off the power supply, which can effectively prevent the TV from being struck by lightning in the human room. Similarly, all electrical appliances should be unplugged after use.

Electrical equipment must be placed in a dry, clean and ventilated place. It is best to electrify and heat electrical equipment once a week for a long time to prevent fainting, moisture and rust. Many people like to wipe the surface of TV screen with a wet rag when watching TV. This is not correct. Never wipe household appliances with a wet rag when electricity is on. It is best to adjust the electrical equipment to the energy-saving state, the air conditioning temperature should not be too low, and the number of refrigerator doors should be reduced as much as possible. Don't be too bright on TV or computer.

In summer, people are prone to sweating, so their resistance is correspondingly reduced, and the safety factor against electric shock is relatively weakened. Therefore, more attention should be paid to safety when touching electrical equipment to avoid electric shock accidents. If you find abnormal noise, smell, smoke, fire, etc. When, should immediately disconnect the power.

3. What should I pay attention to in summer electricity safety knowledge?

It is hot in summer, and household appliances are used frequently at this time.

In high temperature season, people sweat a lot and their hands often sweat, but sweat is conductive, and the resistance of sweaty hands and dry hands is different. Therefore, under the same conditions, the possibility and severity of electric shock when people sweat are above average.

Therefore, special attention should be paid in summer: don't move running household appliances by hand, such as desk fans, washing machines, televisions, etc. If you need to move it, please turn off the switch and unplug it.

Don't go barefoot to repair live lines or equipment in your home. Please put on your shoes and gloves if you need live maintenance.

For electrical appliances that are often used in summer, such as electric shower, desk fan, washing machine, etc. Some practical measures should be taken to prevent electric shock, such as often testing whether the metal shell is charged with an electric pen and installing an electric shock protector (leakage switch). There is much rain in summer, and more water is used. If water enters the house unexpectedly, the power supply should be cut off first, that is, the main switch or fuse in the house should be unplugged to prevent the household appliances being used from accidents due to water entry and insulation damage.

Secondly, after cutting off the power supply, move the household appliances that may be wetted to a place that is not wetted, so as to prevent the insulation from being wetted, which will affect future use. If the electrical equipment is soaked in water, it is likely that the insulation will get wet. Before using it again, use a special shaking table to test the insulation resistance of the equipment.

If it meets the specified requirements, it can be used, otherwise it should be dried until the insulation is good.

If the fuse is blown frequently, a qualified electrician should find out the reason and eliminate the fault. 6. Don't pull the wires around. Don't touch live equipment casually. Switches and fuses can be installed on the ground wire and neutral wire. It is forbidden to connect the ground wire to the tap water and gas pipeline. 7. When the power cord of household appliances is damaged, it should be replaced immediately or wrapped with insulating cloth. When moving electrical equipment, you must turn off the switch first, and then move the equipment. It is not allowed to move with electricity. After the electrical equipment with metal shell such as motor is moved to a new location, the grounding wire should be installed first, and the equipment should be inspected to confirm the equipment.

6. Pay attention to how to use electricity safely in summer.

Summer is the frequent season of farm electrical safety accidents. It should be noted that: (1) In summer, people's limbs are prone to sweating and dampness, so it is not advisable to contact electrical appliances frequently to prevent electric leakage from hurting people.

(2) When moving running household appliances (such as electric fans), cut off the power supply first to prevent mechanical accidents. (3) Electrical appliances that have not been used for a long time should be maintained with electricity frequently to prevent leakage accidents caused by corrosion, dampness or insulation deterioration from affecting the service life of electrical appliances.

(4) For electrical appliances (such as electric fans and washing machines) that are often easily encountered, you can always use a pencil to check whether the electrical enclosure is charged. See question 28 for the inspection method.

(5) The electric shower should be installed by professionals, with reliable electric shock prevention measures, and the power supply should be disconnected before use. (6) In summer, there is much rain, and electrical appliances that have been soaked in water can only be used after confirming that the unique edges are not damaged.

Whether the insulation is damaged can be confirmed by testing the insulation resistance with a shaking table. Simple electrical appliances (such as electric fans, table lamps, toasters, etc.). ) It can only be used after drying, but if the fuse or leakage protector is found to be damaged during the first power-on, it should be used with care.

7. What safety should I pay attention to when using electricity in summer?

In view of the frequent occurrence of disastrous weather such as rainstorm and thunder and lightning in summer, and the increase of electricity load, in order to ensure the normal power supply and use in summer, improve the reliability of power supply and safe use, and ensure the smooth development of safety production.

The inspection scope covers the station office building, canteen, computer room, power distribution room, driveway, sentry box and other key power consumption places. Check the rainproof, leakproof and moistureproof conditions of facilities and equipment; Check whether the line diameter and load switch of power supply equipment match the actual load; Check whether the three-phase load distribution is balanced and whether the line connection is safe and reliable; In view of the power failure caused by the increase of thunderstorms in summer, the generator is maintained and put into trial operation, and sufficient fuel is prepared to ensure emergency power supply at any time.

During the inspection, it was found that the overall electricity consumption was safe and electricity saving was good, but it was also found that some players did not unplug the electrical plug after leaving, and some sockets in the booth were damaged. Timely rectification found safety problems and hidden dangers.

Through the inspection, the potential safety hazards were eliminated, which laid a solid foundation for ensuring the smooth realization of various work objectives and created a safe and stable charging environment for toll stations.
