Embodiment Construction

[0029] The present invention will be described in detail below in conjunction with the embodiments and the accompanying drawings.

[0030] A method for manufacturing a dual-power output energy-taking magnetic core, specifically comprising the following steps:

[0031] A. Obtain the grid environment parameters and determine the magnetic core limit: bus current I 1 =3A, grid frequency f=50Hz, output power P 1 =0.03W when the secondary filter circuit voltage U C1 =1.2V, output power P 2 =0.05W, the secondary filter circuit voltage, U C2 = 1.5V.

[0032] The energy-taking magnetic core selects the toroidal wound core. The size limit of energy harvesting magnetic core is: inner diameter d=[0.065,0.075]m, outer diameter D=[0.08,0.09]m, height h=[0.01,0.003]m. According to the size limit of the energy-taking magnetic core, it can be obtained: the cross-sectional area of ​​the energy-taking magnetic core S=[S 1 ,S 2 ]=[5×10- 5 ,7.5×10- 4 ] m 2 . The magnetic path length of...

Abstract

The invention belongs to the field of electricity. The invention relates to a magnetic core, in particular to a manufacturing method of a double-power-output energy-taking magnetic core. The manufacturing method of the energy-taking magnetic core is based on the actual situation of engineering application; firstly, the working state of a magnetic core is pre-judged; a calculation process of an inapplicable unsaturated working state in engineering practice is omitted; coefficient simplification calculation is introduced, the influence of process variables such as magnetic core resistance impedance, leakage inductance voltage drop, magnetic core hysteresis loss and eddy current loss in a numerical algorithm and the difference of theoretical calculation and engineering application are compensated through coefficients, a complete output power calculation method is formed, and the method is convenient, simple and convenient to apply. The single energy-taking magnetic core power supply provides two kinds of output power, the application of the energy-taking magnetic core is expanded, the output power of the magnetic core is quantified, the output can be directly applied to a post-stage circuit, a power control circuit does not need to be added, the production cost is reduced, the production efficiency is improved, and the circuit space is saved.

Description

technical field [0001] The invention belongs to the field of electricity, and relates to a power-taking technology of a power transmission line detection device, in particular to a method for calculating and manufacturing an energy-taking magnetic core according to actual engineering application conditions. Background technique [0002] In recent years, as the scale of the distribution network has become larger and larger, the grid structure has become more and more complex, which has put forward higher and higher requirements for the power quality and reliability of the distribution network. It is necessary to install line monitoring equipment on the high-voltage transmission line to ensure the normal and safe operation of the high-voltage transmission line. High-voltage side measurement equipment such as photoelectric current transformers, transmission line temperature measurement equipment, etc. directly measure the high-voltage side information, and then transmit the col...
