Embodiment Construction

[0023] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0024] The present invention adopts distributed measurement; if wireless communication is used to complete the measurement, the coupling of the DC high voltage and the communication signal can be released, and a lower relative voltage can be directly measured at a suspended high potential without the need for a huge distribution piezoresistor stack. Based on this idea, the present invention proposes a distributed measurement system. By arranging voltage measurement nodes at key points of the accelerator (positions that are prone to high-voltage ignition and high failure rate points in the accelerat...

Abstract

The invention discloses a voltage fault monitoring system and method for an electron irradiation accelerator. The system comprises n voltage detectors which are used for detecting the voltages of n to-be-measured points, and also comprises a communication node network and a database. The communication node network consists of n communication node network units and one network access point unit, thereby forming a star-shaped topological structure. The n communication node network units are connected with the network access point unit in a mode of wireless communication. The network access point unit is connected with the database through a network line. The input ends of the n voltage detectors are respectively connected with n voltage to-be-measured points in the accelerator, so as to collect the voltages of the to-be-measured points. The output ends of the n voltage detectors are respectively connected with n communication node units. According to the data in the database and a preset fault status data, the voltage fault status of the accelerator is obtained. The system can accurately positioning the fault position through the detection of the voltage of a key part.
