1. The shell of the dense bus duct is assembled with profiles to enable it to withstand strong electric and thermal stresses. According to the data, it passes the dynamic thermal stability test, and the bus shows no perceptible permanent deformation after the test. 2. The dense bus duct conductive bar is covered with multi-layer insulating materials, and can withstand 3750V power frequency withstand voltage. 3. The insulation resistance of each section of the dense bus duct shall not be less than 20M Ω under the normal condition that the ambient air temperature is 20 ± 5 ℃ and the relative humidity is 50~70%. 4. In the long term, intensive bus duct
Detail
Generally speaking, substations will have multiple 10KV outgoing lines, and one 10KV outgoing line may have multiple user loads. In case of single-phase grounding and short circuit fault of 10KV line, if the fault point cannot be quickly and accurately isolated, the fault isolation range may be expanded and normal power consumption of users in non fault section may be affected. The intelligent vacuum demarcation switch controller can quickly and accurately remove the user's short circuit fault and isolate it

For decades, microelectronics technology has promoted the development of sensor technology. Therefore, the whole industry must establish the sense of innovation, vigorously strengthen the development of new sensors, improve the cost performance ratio of products, accelerate the transformation of scientific research achievements, accelerate the industrialization of new sensors, and rapidly increase the market share of domestic sensors. At present, the sensor industry in China is small in scale and narrow in scope of application. Therefore, it is urgent for us to change our concept and change the research and development of sensors from single physical property sensing
