Problems solved by technology
[0004] However, when the field mill sensor is used to measure the DC synthetic field strength, the electric field distortion at the platform or balcony is caused by the grounding wire and the metal plate above the field mill, resulting in inaccurate measurement results of the DC synthetic field strength; at the same time, poor grounding of the grounding wire will lead to Accumulation of space charges causes errors in the measurement results of DC synthetic field strength

The invention relates to a measuring device, a measuring system and a measuring method for space DC synthetic field strength. The rotating assembly includes a first rotating body, a second rotating body and a circuit board, and the circuit board is detachable from the first rotating body and the second rotating body. connected, and the circuit board is electrically connected with the first rotor and the second rotor; one end of the drive assembly is connected with the circuit board; the flow of the measurement method: generate induced current-generate induced voltage-display the measurement result; through the first rotor and The second rotating body rotates, so that the intensity of the electric field received on the rotating component changes periodically, and the corresponding induced charge also changes periodically, and the corresponding induced current can be measured by using the induced current formed by the periodically changing induced charge. Field strength, compared with the traditional measurement method of DC combined field strength in balcony or platform space, it avoids space charge accumulation caused by poor grounding, thus improving the accuracy and convenience of measuring DC combined field strength in balcony or platform space .
Description
Technical field [0001] The present invention relates to the technical field of power systems, particularly to a DC spatial field strength measuring apparatus, measuring method and measuring system. Background technique [0002] Now, with the ultra-rapid development of UHV power grid and growing awareness of environmental protection, the environmental impact of electromagnetic power transmission project received more attention, the DC field strength electromagnetic environment as a DC transmission project an important indicator of a direct impact on circuit design, construction and environmental inspection, accurate measurement of the resultant field is very strong sense DC significant. [0003] When conventional measuring field strength of a DC field ground sensors are used to monitor terrestrial field strength, for monitoring a balcony or terrace, requires a ground line, a ground line extending from a balcony or a platform to the ground, while the upper field of grinding to be s...
