“Electric workers have climbed the transformer to remove the wires, and there is no power outage?†On May 9, the residents near the Union Building in Boluo County issued such a sigh.
On the same day, the Boluo Power Supply Bureau upgraded the power grid. The area around the Zhongyuan 1st Road and the Northeast Road of Luoyang Township in the county town should be equipped with power outages. The construction time is from 7:00 am to 21:00 pm. In order to protect the residents' normal living and electricity consumption, the power supply department has opened 7 emergency power generation vehicles to provide power for 2,105 households.
"When the power sector came to the construction, the home had to be powered off." Resident Zhang said with emotion. "The most troublesome thing about power outages is that you can't cook rice with rice cookers. It can only be cooked in a gas stove. It is really inconvenient. But this time there is no The problem of power outages."
According to reports, the construction involves four 10 kV lines and nine transformers, involving 2,105 households in the power outage area. In order to minimize the impact of power outages, Luoyang Power Supply takes measures such as load transfer and temporary power supply for mobile power vehicles. For more than ten hours of construction time, only a short pause in the process of picking up the mobile power car is required.
This line maintenance is not simply to replace the old equipment, but to accelerate the realization of the distribution network automation. Since 2018, Luoyang Power Supply has invested about 200 million yuan to speed up the renovation and upgrading of a new round of power grids. It plans to build 15 new 10 kV lines and add and replace 198 distribution boxes. "Using automation equipment, it can be realized that if the A line is faulty, the equipment automatically switches from the B line to supply power, that is, the non-fault area load is automatically transferred." Luo Feng Power Supply Assistant Assistant Peak explained the concept of distribution network automation to the reporter.
"The transformation of the power grid is to improve the reliability of power supply. The electricity consumption problem in the process must also be concerned," said Gao Feng. “In the future, as long as the relevant operating conditions, such as the generator car, can be driven in, we can use this method to minimize the impact on the daily electricity consumption of residents.â€
Oil level winding thermometer,Also known as winding temperature controller, winding temperature indicating controller,
Product introduction of temperature controller:
It is mainly composed of elastic element, sensing tube, temperature sensing component, electric heating element, integrated converter and digital display instrument. The temperature packet of the transformer winding thermometer is inserted into the oil hole on the top of the transformer oil tank. When the transformer load is zero, the reading of the winding thermometer is the temperature of the transformer oil; When the transformer is loaded, the current directly proportional to the load taken out through the transformer current transformer flows through the electric heating element embedded in the corrugated pipe after being adjusted by the converter, The displacement of the elastic element increases. Therefore, after the transformer is loaded, the displacement of the elastic element is determined by the top oil of the transformer and the load current of the transformer. The temperature indicated by the transformer winding thermometer is the sum of the transformer oil temperature and the temperature rise of the coil to the oil, reflecting the temperature of the hot part of the measured transformer coil.
