Embodiment Construction

[0020] The present invention will be further described in detail below in conjunction with the accompanying drawings, so that those skilled in the art can implement it with reference to the description.

[0021] Such as figure 1 As shown, the present invention provides an AC / DC mixed electric field detector, which includes a moving piece 110 and a fixed piece 120 arranged on the probe. The moving piece 110 and the fixed piece 120 are both arranged on the rotating shaft 130 , the moving piece 110 is arranged on the upper part of the rotating shaft 130 , and the fixed piece 120 is arranged on the lower part of the rotating shaft 130 , and the rotating shaft 130 is driven to rotate by the motor 140 . The moving piece 110 is fixedly connected with the rotating shaft, can rotate with the rotating shaft 130, and is directly grounded. The stator 120 is sleeved on the rotating shaft 130, does not rotate with the rotating shaft 130, and is grounded through a resistor. The moving piec...

Abstract

The invention provides an AC and DC hybrid electric field detector, which comprises multiple stator plates and multiple rotor plates, wherein the stator plates are uniformly arranged in a circumference, the contour of the stator plate presents a Bernoulli twisted wire shape, and the stator plate is fixed and does not move and is grounded through a resistor; the rotor plates are uniformly arranged in a circumference, the rotor plate is fan-shaped, and the rotor plate is directly grounded; the rotor plate is arranged at the upper part of the stator plate, the stator plate and the rotor plate are insulated mutually, the rotor plate is driven to rotate under a driving mechanism, an electric field passes through the adjacent two rotor plates and acts on the stator plate, and when the rotor plate rotates above the stator plate, the electric field can be shielded. According to the AC and DC hybrid electric field detector provided by the invention, as the Bernoulli curve-type stator plate is adopted and the designed stator plate structure is used, when the rotor plate rotates, the stator plate areas exposed in the electric field present sine variation, a mathematical table for the area variation is deduced starting from a mathematical principle, and the electric field can be measured more accurately and more reliably.

Description

technical field [0001] The invention belongs to the technical field of electric field strength detection equipment, and in particular relates to an AC / DC hybrid electric field detector. Background technique [0002] In recent years, my country's land resources have become increasingly tense, and the cost of building new transmission corridors in economically developed areas is relatively high, accompanied by the construction of so many UHV transmission lines. This requires the power industry to increase the utilization of existing transmission corridors and achieve compact transmission. At present, the situation that UHV DC lines and AC lines are erected in the same corridor has already appeared. In the design of UHV transmission lines, the ground field strength is an important design principle, so accurate measurement of the mixed electric field at the ground of the AC-DC parallel transmission corridor will play an important guiding role in the design of AC-DC parallel tra...
