How to prevent electric fires

For high-power electric heating appliances, separate switches and A*-Ping fuses should be used. It is not advisable to plug and unplug the switching power supply. Because the plug directly into the AJ is easy to cause a short circuit to generate an arc; it is also not allowed to directly plug the f into the socket of the lamp holder. Because the current on the lamp holder exceeds 3A, it is easy to cause an accident. The wire connecting the electric heating appliance must meet the capacity requirements of the electric heating appliance. The plastic insulated wire should not be used as the power lead, but the insulated sheathed cord should be used.

Min 3 electric heating appliances should be placed on non-combustible bases such as mud bricks and slate, and should not be placed directly on wooden benches or platens to avoid burning and igniting. Keep away from flammable and explosive materials during use or when using uncooled heating appliances.

It is strictly forbidden to use electric heating appliances in places with flammable gases and flammable liquids.

5 should pay attention to the daily maintenance of electric heating equipment, must be checked before use, can not be used when the power supply lead of the electric heating appliance is damaged, aging or the switch, plug and fuse are defective.

6 The power lines and sockets of household electric appliances should be selected according to the load of household appliances, and the wires and sockets that meet the specified standards should be selected and installed by the electrician.

The simple method of heat sealing knife switch bookmark0 (246630) Chenglin Zhaihe Hydropower Station in Yuexi County, Anhui Province At present, the main circuit of low-voltage power distribution screen mostly uses HD series knife switch and DW series circuit breaker. Since there is no interlock between the knife switch and the circuit breaker, it is easy to cause a malignant accident with a load pull and a knife switch. I have explored a simple method in my work practice to prevent such a vicious accident. Now introduced to everyone, for.

Install a micro switch in the appropriate position behind the screen, so that the knife switch operating handle is in the range of 45.~150., and ensure that the micro switch operates reliably under the action of the knife switch link. For a circuit breaker with a trip coil, the moving contact of the micro switch can be connected in parallel with the trip button of the control circuit breaker, or the breaking contact of the micro switch can be connected in series to the DW breaker for voltage loss tripping. In the coil loop. In this way, whether the knife switch is opened or closed, the micro switch is in the action state at the moment when the knife switch and the static contact are in contact or disconnected, ensuring that the DW breaker is in the opening position, and the belt is fundamentally eliminated. The possibility of load pulling and closing the switch can prevent the accident from happening.

When installing the micro switch, it is necessary to select a safe and reliable fixed position according to the actual position of the knife switch handle to ensure reliable operation and safe operation. According to statistics from relevant departments, according to the statistics of relevant departments: With the improvement of the living standards of our people, the output and consumption of various types of batteries have risen sharply. At present, China's annual battery consumption is about 7 billion knots. The waste battery contains a large amount of heavy metals such as mercury, pot, aluminum, and chromium. Toxins other than mercury and aluminum are well known, while cadmium causes osteoporosis and rickets. Waste batteries are thrown away by weathering and corrosion, and the toxic substances will penetrate into the soil and rivers and lakes, causing pollution of soil and water sources. For example, a button cell can cause contamination of 600nv5 water. This poses a great threat and harm to the health of humans and various animals. At present, Nanjing has built a “concentration camp” for used batteries. The government has called on the public to actively recycle used batteries. There are 4 used battery storage warehouses in Nanjing to ensure the recycling and disposal of used batteries.

In order to ensure that the dispatch attendant can remotely operate the unattended substation, we configure the grid operation dash card for the dispatcher background machine and make a bar code card for each shift dispatcher. The card is divided into two types. The scheduling value is held by the monitoring card, and the scheduling sub-value holds the operation card. When the remote operation is required, the scheduling sub-value firstly draws the operation card through the card-splitting device, and then the scheduling value is assigned to the monitoring card. You can then follow the prompts that appear on the interface. While displaying the contents of each remote control operation, the names of the operators and guardians are also displayed, thereby avoiding the occurrence of misadjustment and misalignment accidents. However, the bar code card used for remote operation takes a long time, and the bar code on the bar is worn out, so that the card reader cannot be recognized, and the remote operation cannot be performed normally. In this case, we can only find the dispatching automation equipment manufacturer to solve, not only the price is high, but also the time is long. Through experiments, we found the experience of emergency use of the PIN card, that is, copy the “barcode” on the newly created PIN card (and leave a backup), and when the “bar code” is worn out, copy the corresponding “bar code”. Scotch tape is attached to the top, and it can also be attached to a good quality plastic business card. It is worth noting that the direction of the “bar code” cannot be reversed and should be consistent with the original card.

After a period of use, the unit with the above operational functions may wish to try. 201-6-! 8 Received name / Hou Kunhui gender / male occupation / electrician hobby / music, dating friends / I hope you and I treat each other sincerely.
