Embodiment Construction

[0027] Embodiments of the present invention will be described in further detail below in conjunction with the accompanying drawings.

[0028] The design concept of the present invention is: the present invention converts the levelness in different directions in a high potential environment into optical signals with different color differences, and uses mixed light to represent the levelness after color light synthesis, and transmits it to the low potential end by optical fiber, through the light color- The levelness converter restores the mixed light to the levelness in different directions to realize levelness measurement. The measuring device for realizing the above method is mainly composed of a levelness-light color sensor and a light color-levelness converter. The optical fiber, lens, floating ball, etc. that make up the levelness-light color sensor are all non-metallic insulating materials, and the electric field and magnetic field interference in the high potential envi...

Abstract

The invention relates to a levelness measuring device for a high-potential component of an electrical device and a method thereof. The device comprises a levelness-photochromic sensor and a photochromic-levelness converter. The levelness-photochromic sensor comprises a liquid storage chamber, an adjustment seat, a floating ball, a beam splitting prism, a collimating lens and a convex lens. In addition, the method includes: fixing the levelness-photochromic sensor to an electrical device needing levelness detection and connecting the levelness-photochromic sensor with the photochromic-levelnessconverter by a fiber; outputting three-color light mixed based on different proportions by the upper end and the lower end of the levelness-photochromic sensor based on different levelness values, transmitting the light by the fiber and then receiving the light by the photochromic-levelness converter; and then according to the three-color balancing degree, determining the levelness of an electrical device. Therefore, the real-time monitoring function of the levelness of the high-potential component of the electrical device is realized; the device has anti-interference and chargeable measurement characteristics; and the accuracy and real-time performance of the levelness measurement of the high-potential component are improved effectively.

Description

technical field [0001] The invention belongs to the technical field of electrical equipment operation detection, in particular to a levelness measuring device and method for high potential parts of electrical equipment. Background technique [0002] During the operation of electrical equipment, under the action of factors such as magnetostrictive vibration, dynamic and thermal stability, lead wire tension, and self-gravity, bending and displacement may occur, causing the level of the equipment to change. The levelness of high-potential components of electrical equipment can reflect equipment tilt settlement, stress deformation, etc. However, due to the high electric field strength and strong electromagnetic interference signals around high-potential components, many electronic devices cannot work normally, especially those with high installation positions Electrical equipment, therefore, is difficult to measure the level of high potential parts. [0003] At present, the mea...
