Embodiment

[0050] The electrode layer of the selected core wire is a single copper wire, and its shape is circular.

[0051] The electroluminescent layer is made by mixing and coating electroluminescent material D512 and epoxy resin adhesive. The ratio of electroluminescent material to adhesive is about 1:1, and it is heated, dried and cured.

[0052] The transparent conductive layer 4 is made of nanometer indium oxide with a resistance of 6M ohms.

[0053] The outer electrode is a round single copper wire, and the insulating layer is made by mixing and coating the dielectric material lead titanate and epoxy resin adhesive; the ratio between the dielectric material and the adhesive is about 1:1, and it is dried and cured by heating. Distributed in steps, gradually transitioning from thin to thick.

[0054] The transparent sealing layer is silicone rubber, which completely seals the transparent conductive layer; the character mark on the surface of the transparent plastic layer correspon...

Abstract

The invention relates to an electroluminescent voltage transducer. The electroluminescent voltage transducer comprises a core wire electrode, an electroluminescent layer, a high-resistance transparent conducting layer, one or more outer electrodes with different withstand voltages, and a transparent sealing layer with a mark, and is characterized in that: the electroluminescent layer wraps and covers the surface of the core wire electrode; the high-resistance transparent conducting layer is coated on the outer surface of the electroluminescent layer; the high-resistance transparent conducting layer is connected with the outer electrodes; and when the core wire electrode and the outer electrodes are accessed to an alternating current power supply, illuminations with different intensities are correspondingly generated according to different voltages. The electroluminescent voltage transducer can be used for technical data display during power transmission, maintenance, manufacturing, installation and debugging.

Description

technical field [0001] The invention belongs to the technical field of voltage sensor application. Background technique [0002] Voltage detection technology is an important technical data in the process of power transmission, maintenance, manufacturing, installation, and commissioning. Most of the daily high voltage detection is completed by various voltage sensors. Provide results, their advantages are accurate data, easy to summarize, such as: voltage sensor based on Hall principle, etc. But the existing voltage testing devices have general deficiencies, they all can't directly and simply observe the readings, such as field work at night, the voltage value can only be determined by means of equipment and meters. [0003] The invention uses electroluminescent technology, and inspectors can visually judge the voltage range directly according to the luminous intensity, which can be set at the connection of electric equipment, and can be used for voltage indication of indoor...
