1 During periods when power consumption is relatively low, the voltage is likely to be higher than 220 V, such as in the middle of the night, because when power consumption is low, the power demanded from the power network is relatively weak and the power loss on the main road is small. The current on the main road is small and the voltage drop on the main road is reduced. According to the voltage division relationship, the user's circuit voltage is higher.
2 Power supply from the substation to the user's circuit usually requires one end of the distance. Distances vary and longer distances result in greater losses. To ensure reliable power supply, the voltage at road terminals is generally higher than. 220v, so some users' voltage will be higher than 220v
3 All electrical appliance userses The wires are all connected in parallel The current increases during the peak period of electricity consumption, and the power supplied by the. The power plant should be based on P=I*U. It can be seen that as the current increases, the voltage decreases, so the household electricity voltage will be low during the peak period of electricity consumption at 220V
<. h3>Will tap water corrode the water tank of the generator set?How to choose a diesel generator set for the hydropower plant? Precautions for choosing a diesel generator
1. of diesel generator set to buy And the quality must meet the requirements of relevant standards
When purchasing diesel generator sets for communication, you must meet the requirements of relevant regulations.
2. Main factors to consider when purchasing a diesel generator
The main factors to considerThings to consider when purchasing a diesel generator include mechanical and electrical performance, purpose of the unit, load capacity and dimming range, automation capabilities, etc.
(1) Purpose of the generator. Because diesel generators can be used in three situations: regular use, backup and emergency. Therefore, different uses have different requirements for diesel generator sets.
(2) Load capacity of the diesel generator set. The load capacity and load variation range should be selected according to different uses, and the capacity of the single unit and the capacity of the emergency diesel generator of the diesel generator set should be determined.
(3) Environmental conditions for using diesel generator sets (mainly refers to altitude and climatic conditions)
(4) Selection of setsdiesel generators
(5) When purchasing a diesel generator, pay attention to the generator and excitation methods
(6) Selection of automation functions diesel generator
Customers often ask us the same question, who should use tap water. Does replacing coolant corrode diesel generator water tank? Regarding the explanation of this problem, our generator Jiangsu Taizhou Dongkang Co., Ltd. specially organized a technical team to conduct a discussion:
Tap water replacement coolant for generator sets is generally divided into the following types: 1. Well water 2. Water from tap 3, river water. Generally, the main condensable tap water in remote areas is well water, while most customers in urban areas use tap water. Trace elementss present in tap water themselves will not corrode the water tank! The cause of corrosion of the generator set fan cooling water tank is an electrochemical reaction. If it is made of real 304, 316L stainless steel and copper, it will not be corroded at all. the nickel content is insufficient for long-term use. Even pure water without chlorine can corrode! The cooling water tank material of ordinary domestic brand generator sets is generally 202 and 304 stainless steel. Generally, manufacturers use genuine 304 stainless steel materials, while many unscrupulous manufacturers use steel 202 stainless steel. As mentioned above, genuine 304 stainless steel will not corrode when used with tap water. However, after a long time, the chloride ions in tap water will ionize and dowill turn the stainless steel a dark color. If 202 is used, corrosion will occur after prolonged washing and soaking. Therefore, we recommend customers to use at least purified water or tap water. Customers who have conditions can use vehicle coolant directly.
