In order to effectively do a good job in the deployment of the peak winter in 2023 and effectively ensure the implementation of various control measures for the peak winter work, the Chengbei Branch has set up a special working group led by the leaders in charge, including production, marketing, infrastructure, safety and other specialties. So far, the main work is as follows:
1. Fully undertake the implementation of the "Guizhou Power Grid Co., Ltd. 2023 Distribution Network Lean Investigation and Rectification "Autumn Wind Action" Work Plan. The Chengbei Branch, together with the Municipal Management Office, the Street Office within its jurisdiction, the traffic police and other departments, has carried out a total of 50 10kV line channel cleaning work.

2. Vigorously carry out comprehensive maintenance of lines. This year, a total of 40 10kV lines and 37 power outages were carried out (a total of 7 transformers were replaced, 4 new transformers were added, 16 ring main units were replaced, 11 switches were replaced, 3 new switches were added, and 1 new ring main unit was installed) to continuously improve the health level of lines and equipment.
3. Make every effort to tackle the self-healing construction of distribution network lines. This year, the self-healing construction of 42 10kV lines has been completed, and the fault areas are automatically isolated after the line fails, and the power supply in non-fault areas is automatically restored, so as to continuously improve the reliability of line power supply.
4. Carry out special inspections of distribution network lines in peak winter. Combined with the list of important customers in the jurisdiction and the list of heavy overload lines, at least one special inspection will be carried out on the lines involved through the inspection app, focusing on but not limited to: (1) line and equipment joints, wire clamp temperature measurement;(2) Temperature measurement of cables and cable accessories;(3) The partial discharge detection of lines and equipment should be entered in time and the defects should be completed within the specified time. At present, special inspections of 36 lines have been completed.
5. Do a good job in monitoring, prevention and management of heavy overload and low-voltage stations to ensure that there is no overload and burning of distribution transformation during the peak winter.
6. Do a good job in emergency management of the distribution network during the peak winter period to improve the efficiency of power repair. Do a good job of emergency duty, do a good job of comforting customers who have power outages, ensure basic electricity needs, and do a good job in public opinion control. Do a good job in resource allocation, strengthen safety and progress control, safely and efficiently carry out emergency repair work of equipment, replace equipment damage in a timely manner, make records and take photos for retention, and provide a basis for applying for anti-icing reinforcement projects in the coming year.

7. In view of the recent external damage, the Chengbei Branch has reported the fault situation and impact, and the relevant departments have organized the construction unit, the construction unit, and the power supply property right to hold a coordination meeting, establish a municipal road excavation construction reporting mechanism, and strictly implement the "no reporting, no survey, no disclosure, and construction is strictly prohibited", and our bureau will also strengthen the line inspection during the peak winter, strengthen the regional inspection with the risk of external damage, and control the risk of power outage due to external damage in advance.
Question: How to better protect home appliances when encountering the previous power supply equipment failure. (Whether it is necessary to install a protector on the appliance before the power outage, and what should be done after the power outage).
Guizhou Power Grid Co., Ltd. Guiyang Power Supply Bureau Chengbei Branch: After the failure of power supply equipment, the preventive measures for the burning and damage of customers' household appliances mainly involve two aspects:
1. Power supply enterprises should do a good job in the operation and maintenance of power supply equipment to reduce the probability of equipment failure.
2. It is recommended that customers install an undervoltage protector at a suitable position at the back end of the meter for important equipment that is sensitive to voltage fluctuations, and the installation of the undervoltage protector should be based on the technical standards of the undervoltage protector and electrical equipment.
Important activities to ensure power supply at the site.
Question: What are the specific precautions for using electricity in winter?
Guizhou Power Grid Co., Ltd. Guiyang Power Supply Bureau Chengbei Branch: Our company will issue similar warm reminders every year, and the specific suggestions are as follows.
1.In winter, when the air conditioner uses the heating mode, the air conditioner temperature setting can save more than 10% of electricity for every 2 lower, and it is recommended that the air conditioning temperature should be set at about 20 in winter. The air outlet is adjusted downward, which can also save more power.
2.In winter, when turning on bath bombs and electric heaters, it is recommended that the public gradually increase them from low to high, and turn them off in time when not in use.
3.Do not turn on the heating function of the water heater for a long time in winterMembers of the public are advised to choose water heaters with energy-saving functions.
4.Add a waterproof cover to the socket in the bathroom. In view of the relatively humid environment in the bathroom, the water vapor generated during bathing and electricity will easily form a current loop, resulting in accidents, the public is advised to install waterproof covers on the sockets in the bathrooms and conduct regular inspections.
5.The plug on the plug board should be in moderation. In the cold winter, you may often try to plug all the plugs into one power strip, so the chance of accidents will be greatly increased, because installing too many plugs on the power strip will lead to excessive electrical load and potential safety hazards.
6.Although the electric blanket is good, be sure to turn it off before going to bed. There is no heating in southern families in winter, and many citizens will lay electric blankets when they sleep at night, but they must remember to unplug before going to bed, and the power on time should not be too long. In addition, the electric blanket must be tiled, otherwise it is easy to burn the insulating surface of the power cord, causing dangers such as leakage and short circuit.
7.Keep a safe distance from the heating equipment, and it is recommended that the public remember not to place clothes or cover wet objects when using the heating equipment, and keep a certain safety distance between the heating equipment and combustibles. Keep a distance between people and heating equipment.
8.Warm baby in winter is also a commonly used item, it is recommended that the public buy electric heaters, remember to choose waterproof, wear-resistant and easy to clean, remember to check whether the electric heaters and power cords are intact before each charge, do not charge while holding in your arms to warm, which may cause the risk of electric shock, poor quality of electric heaters may also occur**!At the same time, sharp objects or open flames should be avoided to contact the electric heater baby to prevent internal liquid leakage.
