Abstract

The invention discloses an isolated satellite surge current detecting method which comprises the following steps of 1, clamping a satellite positive bus-bar cable bundle by means of a Hall current clamp; 2, connecting the output end of the current clamp with a PC through a signal high-speed sampling device; 3, programming upper computer software by the PC end, and processing and storing a received current signal; and 4, through a man-machine interaction interface, performing comparative analysis, curve real-time displaying, alarming and the like on a surge current value by the PC end. The isolated satellite surge current detecting method has advantages of simple operation, comprehensive, accurate and effective data. The man-machine interaction interface is utilized for realizing higher visuality of a detecting result. A Hall sensor is utilized for performing isolated sampling on the current signal of the satellite positive bus-bar, thereby ensuring isolation between a satellite and ground, and realizing high safety and high reliability. Furthermore the method ensures high accuracy and high safety in satellite surge current detection.

Description

technical field [0001] The invention relates to a satellite surge current detection method, in particular to an isolated satellite surge current detection method. Background technique [0002] The satellite system has a lot of equipment and complex load characteristics. Many stand-alone equipment is not a purely resistive load, but a capacitive or inductive load. Especially in order to effectively suppress interference, each device is designed with a power module with a filter circuit to improve the reliability of the device in the interference environment, and the use of the power module makes the device often present a capacitive load, satellite power supply and distribution When the power distribution system powers up each device, a large surge current will be generated, which can cause secondary pollution of the circuit, and will have a great impact on the normal operation of the power distribution circuit and related equipment. [0003] At present, there are usually th...
