Brief description of the drawings
The measuring system schematic diagram of Fig. 1 line hardware corona loss;
Wherein 1, be gold utensil, 2, be insulation enamelled coating, 3, be metallic conduction enamelled coating, R, is sampling resistor.
Embodiment
Below in conjunction with specific embodiment, the utility model is described in further detail, described in be to explanation of the present utility model instead of restriction.
A kind of measuring system of line hardware corona loss, comprise gold utensil 1, be arranged at gold utensil 1 superficies insulation enamelled coating 2, be arranged at metallic conduction enamelled coating 3, sampling resistor R and the data acquisition system (DAS) of insulation enamelled coating 2 superficies, wherein sampling resistor R one end is connected with gold utensil 1, and the other end is connected with metallic conduction enamelled coating 3.Gold utensil 1 superficies are non-smooth surface or plane, and insulation enamelled coating more easily adheres to.Data acquisition system (DAS) is a multi-channel synchronous data acquisition device, and it comprises first passage and second channel; Voltage signal when first passage is used for gathering hardware corona on sampling resistor R, is used for calculating leakage current; Gold utensil is connected with voltage divider, and second channel, for gathering the voltage signal on voltage divider, is used for calculating the voltage applying on gold utensil.The data of data acquisition system (DAS) collection radio to far-end computer by GPRS module, utilize instantaneous power method to calculate the corona loss that can obtain gold utensil.
Far-end computer is dealt into order in GPRS module by GPRS network, and GPRS module is dealt into order in data acquisition system (DAS) by RS485 interface; After data acquisition system (DAS) data acquisition completes, send initiatively reading out data of read command by far-end computer; GPS connects GPRS module and data acquisition system (DAS), receives the instruction of far-end computer by GPRS module, sends pulse per second (PPS) provide trigger pip for data acquisition system (DAS) to data acquisition system (DAS), controls first passage and second channel synchronous acquisition; Simultaneously GPS provides corresponding gold utensil locating information for far-end computer.
When concrete enforcement, insullac is covered on the line hardware 1 that will measure, insulate completely.Wherein line hardware 1 superficies can be non-smooth surface or plane.After treating insullac bone dry, put metallic conduction enamelled coating 3 at insulation enamelled coating peripheral hardware again, allow and between metallic conduction enamelled coating 3 and measured gold utensil 1, form an electric capacity, line hardware 1, insulation enamelled coating 2 and metallic conduction enamelled coating 3 form the structure of a similar electric capacity like this, the dielectric layer of the electric capacity enamelled coating 2 that insulate exactly.Leakage current while using a sampling resistor R who is connected in parallel on line hardware and metal enamelled coating just by hardware corona is converted to voltage signal; Gold utensil voltage gathers by voltage divider; By analog-to-digital conversion and calculating, can obtain the corona loss value of this line hardware.Insulate in the utility model thickness of enamelled coating 2 and metallic conduction enamelled coating 3, can be by repeatedly brushing and adjust, easy to operate, easily control; Be applicable to any line hardware in irregular shape.
Above-mentioned embodiment is only preferred implementation of the present utility model; the scope that can not limit with this utility model protection, the variation of any unsubstantiality that those skilled in the art does on basis of the present utility model and replacement all belong to the utility model scope required for protection.
