Detailed Description
The present invention is further described below in conjunction with the following figures and specific examples so that those skilled in the art may better understand the present invention and practice it, but the examples are not intended to limit the present invention.
Radio interference is the corona discharge of a high voltage wire to form a corona current which propagates in the wire, thereby emitting electromagnetic waves into space.
In view of the dispersibility of corona discharge, long-time measurement and statistics are needed to obtain the rule; long-term testing was performed using a corona cage test apparatus. The method comprises two parts of current measurement and current modulus conversion theoretical analysis, a large number of repeated tests are required, and accurate radio interference prediction values of the wires can be obtained only by actually measuring in an actual power transmission line.
Since the characteristic quantity of the wire radio interference measurement in the corona cage is the wire corona current, and then the empirical formula estimation of the current-to-radio interference is carried out, certain errors necessarily exist.
On the other hand, from the frequency analysis of the corona current, the corona current has a small component above 30 MHz; the radio interference is mainly concentrated below 4MHz, so the radio interference is mainly measured in the range of 4-30 MHz at present; the corona cage test device is limited to sampling frequency, only 0.5MHz radio interference is generally analyzed, and the 0.5-4 MHz radio interference is obtained according to the frequency characteristic of the corona cage test device.
With the development of radio services, radio frequencies are higher and higher, and more events causing interference to adjacent radio stations by a power transmission line are generated, wherein the events mainly focus on a frequency range of 30-300MHz, which is generally called television interference.
The corona cage test can conveniently simulate television interference under the conditions of different wire models, different configuration parameters, different climatic altitudes and the like, but the biconical antenna, the log periodic antenna and a tripod with the height of 2 meters cannot be erected in the corona cage test device.
The invention provides a patch antenna for television interference measurement, a television interference measurement device and a television interference measurement method.
As shown in fig. 1, 2, and 3, the patch antenna for television interference measurement according to an embodiment of the present invention employs a double "T" shaped monopole patch antenna structure. The patch antenna is a double-sided copper-coated dielectric substrate 20; preparing a T-shaped structure on the front surface of the dielectric substrate by adopting a chemical etching method to form a radiator 10; the back side of the dielectric substrate is a ground plane 30.
Preferably, the width W of the radiator 10 is 91mm ± 0.1mm, the height H is 75mm ± 0.1mm, and the gap is double "T" on the front surface of the rectangular dielectric substrate.
A first notch is formed on the upper side of the radiator 10; a second notch is formed at the lower side of the radiator 10;
the first notch is symmetrical along the longitudinal center line of the radiator (extending along the height direction of the radiator);
the second notch is symmetrical along the longitudinal center line of the radiator (extending along the height direction of the radiator);
the first notch and the second notch are symmetrical along a transverse center line of the radiator (extending in a width direction of the radiator).
The first gap sequentially forms a first gap 101 and a second gap 102 from outside to inside along the height direction of the dielectric substrate; the width of the copper medium on the left side and the right side of the first gap 101 is 30mm +/-0.1 mm, namely the width W1 of the first gap is 31mm +/-0.1 mm; the height H1 of the first gap 101 is 20mm + -0.1 mm; the height H2 of the second gap is 24mm +/-0.1 mm; the width W2 of the second gap is 61mm + -0.1 mm.
The second gap sequentially forms a third gap 103 and a fourth gap 104 from outside to inside along the height direction of the dielectric substrate; the width W3 of the third gap is 31mm +/-0.1 mm; the height H3 of the third gap 101 is 20mm +/-0.1 mm; the height H4 of the fourth gap is 24mm +/-0.1 mm; the width W4 of the fourth gap is 61mm + -0.1 mm.
Preferably, the dielectric substrate has a thickness of 0.5mm and a dielectric constant of 2.5.
Specifically, the feed-out point of the radiator is arranged in the middle of the lower groove of the first notch or the upper groove of the second notch; and feeding power in a coaxial manner.
It should be noted that moving the feed-out point within the range of radius within 3mm in the middle of the lower groove or the upper groove does not substantially affect the performance of the antenna.
Specifically, the feed-out point is connected to the voltage terminal of the coaxial connector 100, and the circular groove 301 provided on the ground plate 30 is connected to the ground terminal of the coaxial connector 100.
Specifically, the coaxial connector 100 is a 50 Ω BNC type connector, the outer conductor radius is 4.50mm, the inner conductor radius is 1.00mm, and air is filled between the outer conductor and the inner conductor.
Due to the high potential gradient on the surface of the wire of the high-voltage transmission line, local air ionization on the surface of the wire is caused, so that local breakdown is formed, and the local discharge is called corona. The corona creates high frequency corona pulses in the space around the wire, with the individual pulses of the corona discharge being very narrow, with pulse widths on the order of 0.1 mus. Considering the resultant effect, a "steady-state" current with a high pulse repetition rate is formed in the conductor, so that "steady-state" radio interference with a high pulse repetition rate is formed around the power conductor. Corona discharge often occurs near the positive and negative peak values of power frequency, a series of pulses form a pulse group, and the waveform of the pulse group is also quite irregular. The duration of the pulse group is 2-3 ms. Such a series of pulses necessarily generates a rich high frequency component.
Specifically, the radio interference forms an induced voltage on the patch antenna of this embodiment.
Fig. 4 shows the patterns of the patch antenna at frequencies of 30MHz, 100MHz and 300 MHz. As can be seen from fig. 4, when the patch antenna operates at 30-300MHz, the main lobe of the directional diagram covers the power transmission line on the plane perpendicular to the extension plane of the patch antenna; therefore, the extension plane of the patch antenna is arranged in parallel to the inner wall surface of the corona cage, so that the television interference of the power transmission wire can be tested in an omnidirectional manner.
Fig. 5 shows a standing wave ratio diagram of the patch antenna. As can be seen from fig. 5, the available bandwidth of the standing-wave ratio VSRW <2 is 28-380 MHz; that is, the working frequency of the patch antenna covers the testing frequency range of the television interference of 30-300 MHz.
When television interference measurement is carried out on a transmission conductor based on a corona cage, the patch antenna is arranged on the inner cage wall of the corona cage, wherein a radiator faces the transmission conductor, and a ground plate is connected with the inner cage wall of the corona cage in a mode (such as double faced adhesive tape) convenient to separate; after high voltage is applied to the power transmission wire, television interference generated by the power transmission wire is transmitted in space and transmitted to the patch antenna to form induced voltage; the induced voltage signal is transmitted to a radio interference receiver in real time, and a television interference signal with the frequency range of 30-300MHz can be measured.
It should be understood that the radio interference receiver as an antenna signal receiving device has an operating frequency of not lower than 300MHz, has peak and quasi-peak detection modes, and meets the bandwidth requirement of 30MHz radio interference measurement specified by the inter-national institute of electrical and electronic engineers committee CISPR for radio interference special committee.
Specifically, the radio interference receiver processes the received induced voltage signal to obtain the frequency characteristic and amplitude of the television interference.
In the corona cage test, the power transmission conductor is generally several tens of meters long. In such a large space area, it is not beneficial to improve the test efficiency by only using one antenna and measuring one point.
In addition, in order to further reduce random errors, a mode that a plurality of antennas are arranged at intervals along the length direction of the power transmission conductor can be adopted, and a plurality of patch antennas are arranged in one test to simultaneously measure the television interference of the power transmission conductor.
Specifically, as shown in fig. 6, the corona cage outer cage body 2 is supported by the corona cage supporting device 1; the three patch antennas 5 are uniformly arranged on the bottom wall of the inner cage body 3 of the corona cage, and the radiator and the dielectric substrate are parallel to the plane of the cage wall; the three patch antennas 5 are connected to the input of a multi-antenna switching device 6 (e.g. a multi-way switch) by low-loss cables provided with BNC connectors; the output of the multiplexer is connected to an antenna signal receiving means 7 (e.g. a radio interference receiver) via a low loss cable; the radio interference receiver can measure a television interference signal of 30-300MHz when a corona discharge occurs in the power conductor 4.
Since the radio interference receiver usually has only one input port, a test data fusion device 8 (e.g., a control and data fusion computer) is provided, and the control and data fusion computer communicates with the radio interference receiver through a communication method (e.g., a serial port, a usb bus, a GBIP interface, an industrial ethernet, etc.) disclosed in the prior art, so as to obtain the frequency characteristic and the amplitude of the television interference measured by the radio interference receiver in real time.
Preferably, the control and data fusion computer communicates with the multi-way switch through a communication method disclosed in the prior art (such as a serial port, a usb bus, a GBIP interface, an industrial ethernet, etc.), and controls the multi-way switch to connect the three antennas with the radio interference receiver one by one according to a preset sequence, so that the radio interference receiver measures induced voltages from the three antennas in turn, thereby determining a 30-300MHz television interference signal radiated by the power transmission line to the space.
In view of the fact that the transmission conductors are generally dozens of meters long, in order to further reduce line loss, the multi-way change-over switch can be installed on the cage body; each patch antenna is connected to the input end of the multi-way change-over switch by a low-loss cable; and the output of the multiplexer switch is connected to a remote radio interference receiver by a low loss cable.
The loss of the low-loss cable does not exceed 3 dB.
Preferably, the control and data fusion computer takes an average value of the measured values corresponding to the three antennas in one test period as the tv interference fusion data of the power transmission line, that is, the tv interference value. Table 1 shows radio interference values of 30-300MHz radiated by the power conductor shown in FIG. 6 at typical frequency points.

In addition, the measuring device of the embodiment facilitates various test scenes, such as changing the specification, the splitting distance, the splitting number and the like of the power transmission conductor.
In addition, the measuring apparatus of this embodiment is applicable to both an ac power transmission conductor and a dc power transmission conductor.

The equivalent substitution or change made by the technical personnel in the technical field on the basis of the invention is all within the protection scope of the invention. The protection scope of the invention is subject to the claims.
