Description

technical field [0001] The invention belongs to the field of high-voltage power supply connection devices for electron accelerators, and in particular relates to the connection between a single high-voltage power supply and multiple electron acceleration systems. Background technique [0002] At present, electron beam flue gas desulfurization and denitrification technology, electron beam sewage treatment technology, etc. all require high-power electron accelerator devices. The accelerator power of electron beam flue gas desulfurization and denitrification is related to the power of thermal power generating set (that is, the amount of flue gas), which accounts for about 1% of the power of generating set. For a thermal power plant unit with a power of 200-500MW, the power of the electron accelerator of the corresponding desulfurization and denitrification device is about 2-5MW. The electron beam current intensity is 1A or higher, because the upper limit of the electron beam c...

AI Technical Summary

Problems solved by technology

The electrical connection between the high-voltage power supply and the electron acceleration system uses a DC high-voltage cable. The withstand voltage of the DC high-voltage cable is lower than 800Kv, and the manufacture of the DC high-voltage cable and the cable head is very expensive.

A foreign high-power electron accelerator used for flue gas desulfurization and denitrification technology adopts the mode that a single high-voltage power supply supplies power to two electron acceleration systems through a high-voltage distributor. The power supply and the electron acceleration system are completely hard-connected. Very high accuracy requirements, at the same time bring high manufacturing costs, installation costs and operating costs

And due to the limit value of the high-voltage distributor's own structure, it is difficult for the number of electron acceleration systems to exceed two
