The invention relates to a sensor for testing the electrical parameter of high voltage lines, which is a new generation of sensor that combines a monolithic integrated central processor, a media access controller and a radio frequency processor into a whole, takes a wireless singlechip as a core, realizes the testing of the electrical parameter of the high voltage lines by extending the peripheral hardware circuit and the software filtering and has the function of detecting the electricity, measuring the voltage, the frequency and the phase of the high voltage lines and sending out the measurement result by the 2.4G public frequency band in a wireless manner; the auxiliary receiving equipment of the testing sensor can receive the information collected by a plurality of sensors for testingthe electrical parameter of the high voltage lines at the same time, classify, process, store and directly display the information according to the requirements of users. When in embodiment, the testing sensor of the invention can be conveniently embedded into the arms of the high voltage working robots or work as an independent device for testing the electrical parameter of the high voltage lines owing to small size, low power consumption and power supplied by lithium cell. The testing sensor of the invention has the advantages of convenient and safe installation and application as well as reliable performance.
Description
1. Technical field [0001] The invention relates to a sensor device for detecting electrical parameters of a high-voltage line, in particular to a device for collecting electrical parameters of a high-voltage line by using wireless single-chip technology and sending detection result information to a receiving device through a public frequency band. It belongs to the field of electronics and information. 2. Background technology [0002] At present, amplitude, frequency, and phase are the three major elements of AC signals. Analysis of AC signals generally only needs to consider the amplitude and frequency. However, in some special cases, high and low voltage lines need to detect phase and phase difference. For example, the detection of the unbalance degree of three-phase electricity needs to measure the phase difference of the three-phase line voltage, and the detection of the resistive current of the arrester needs to measure the phase difference between the voltage and th...
