Description

Technical Field

[0001] The utility model relates to the technical field related to high voltage electricity, in particular to a high voltage combined electrical appliance conductor connection structure. Background Art

[0002] High voltage electricity refers to the household line with AC voltage of 1000V or above or DC voltage of 1500V or above in the distribution line. Low voltage electricity refers to AC voltage below 1000V or DC voltage below 1500V. The safety voltage does not exceed AC 36V and DC 50V. The AC voltage level of 1000KV and above in the power system is ultra-high voltage power supply. It is usually only used as a large power long-distance transmission line because it can reduce the energy loss in the transmission process. The voltage used in different fields is different. In order to reduce the loss of electric energy in the transmission process, the current must be reduced. To ensure that the total power remains unchanged, the voltage must be appropriately increased. After passing through the step-down substation, it finally reaches the user's home. Compared with ordinary power supply, high voltage electricity has its special hazards. There are two special situations of high voltage electric shock: one is high voltage arc electric shock, and the other is step voltage electric shock. Because the voltage is very high, it is easy to electrocute people to death, so pay attention. The conductor connection structure of the high-voltage combination electrical appliance currently used cannot achieve stable connection of the conductor and reduce the loss caused by high voltage leakage. Therefore, we introduce a high-voltage combined electrical conductor connection structure. Utility Model Content
