Abstract：This paper discussed the operation rules and maintenance methods of high voltage systems for Varian Trilogy and Elekta
Precise linear accelerator, made a comparative study on the structural principles and fault maintenance of the two types of highpressure
systems, and analyzed two maintenance cases, including the interlocking faults of UDR1 and UDR2 of Trilogy accelerator
and the fault of Precise accelerator without beam. They were solved quickly by replacing D-Q thyratron of Trilogy accelerators and
optical cable of Precise accelerator. It is found that for the hospital with two types of accelerators at the same time, the comparative
study of the high pressure system of the two accelerators can make the maintenance method regular and improve the maintenance
efficiency.
