Description
Technical field
The utility model relates to a kind of voltage sensor, especially based on metal oxide arrester dividing potential drop molded breadth voltage sensor frequently.
Background technology
That the various superpotential that electrical power system transient superpotential on-line monitoring system requires to suffer electric system are carried out is complete, in real time, record exactly.These superpotential amplitudes and frequency range are all very wide in range, except requiring to adopt high-speed data acquistion system, the amplitude linearity, response frequency and bandwidth to voltage sensor have higher requirement, and also requirement can be carried out easily scene and installs and ensure in electric system long-term safe operation simultaneously.
Utility model content
The technical problems to be solved in the utility model is to provide a kind of based on metal oxide arrester dividing potential drop molded breadth voltage sensor frequently.
The utility model is achieved through the following technical solutions.
A kind of based on metal oxide arrester dividing potential drop molded breadth voltage sensor frequently, comprise high pressure port, metal oxide arrester, sampling unit, above-mentioned metal oxide arrester input end connects above-mentioned high pressure port, and output terminal connects above-mentioned sampling unit, and above-mentioned sampling unit connects the earth.
Further, above-mentioned sampling unit is metal oxide valve block.
Determine metal oxide arrester high pressure dividing potential drop molded breadth frequently voltage sensor intrinsic standoff ratio be the thickness ratio of metal oxide arrester and sampling unit.The voltage signal of output obtains from sampling unit and two ends, ground.
The beneficial effects of the utility model:
Changed protected mode in the past, by the voltage division processing of metal oxide arrester, sampling unit, metal oxide arrester is as high-voltage arm; sampling unit is as the form execution work of low-voltage arm; whole apparatus structure suggestion, easy-to-use, effect is better.
Brief description of the drawings
Fig. 1 is that the implementation case is based on the metal oxide arrester dividing potential drop molded breadth structural representation of voltage sensor frequently.
Embodiment
According to drawings and embodiments the utility model is described in further detail below.
Fig. 1 is that the implementation case is based on the metal oxide arrester dividing potential drop molded breadth structural representation of voltage sensor frequently, with reference to Fig. 1, the utility model, based on metal oxide arrester dividing potential drop molded breadth voltage sensor frequently, based on metal oxide arrester dividing potential drop molded breadth voltage sensor frequently, comprise high pressure port 1, metal oxide arrester 2, sampling unit 3, metal oxide arrester 2 input ends connect high pressure port 1, output terminal connects sampling unit 3, and sampling unit 3 connects the earth 4.
Further, above-mentioned sampling unit 3 is metal oxide valve block.
The high-voltage arm of this voltage sensor using Zinc-Oxide Arrester as voltage sensor, selects with the approximate zinc oxide valve plate of all kinds of parameters as low-voltage arm, can realize the voltage signal conversion of high pressure, UHV (ultra-high voltage) and extra-high voltage electric power system under certain degree of accuracy.
The utility model, has changed protected mode in the past, by the voltage division processing of metal oxide arrester, sampling unit; be metal oxide arrester as high-voltage arm, sampling unit is as the form execution work of low-voltage arm, whole apparatus structure suggestion; easy-to-use, effect is better.
Above-described embodiment is only explanation technical conceive of the present utility model and feature, and its object is to allow the personage who is familiar with this art can understand the utility model content and be implemented, and can not limit protection domain of the present utility model with this.All equivalences of doing according to the utility model Spirit Essence change or modify, and all should be encompassed in protection domain of the present utility model.
