Fiber FP Sensing Simulation for PD-induced Acoustic Emission

Gao dianya jishu (2008)

Mingzhong Xu

A system based on Fabry-Perot(FP) acoustic sensor is designed for on-line detection of ultrasonic signals generated by partial discharges in transformer oil.FP cavity as sensing unit of the sensor is formed between a quartz diaphragm and an end of fiber pigtail.Acoustic vibration reacted on the diaphragm that modulates the incident light wave was used to monitor transformer in service by demodulating output signal involved PD information.In order to decrease difficulty in processing FP sensor and response signal with high frequency,the demodulation using Fiber Bragg Grating(FBG) was adopted in the system.The system with dielectric structure has inherent immunity to electromagnetic interference.The theoretic analysis and computer simulation show that the system is one of choices to measure acoustic emission by PD in transformer in service.

Study on Temperature Rise Characteristic of LED Lighting Fixture under Different Conditions

2022 20th International Conference on Optical Communications and Networks (ICOCN) (2019)

Limin Hu Mingzhong Xu Binqing Wu Zhangwan Wang Lei Zhang

The temperature rise characteristic of LED lighting fixture under different conditions was studied in the paper. The experimental results showed that the temperature rise of LED lighting fixture under the condition of with cover and no dust was about 1.5 times higher than that of LED lighting fixture under the condition of no cover and with dust. Apparently, the influence of the cover on the heat dissipation of LED lighting fixture was much larger than the dust.

Inthepresent paper, thedielectric properties ofpolypropylenes withdifferent crystal formswere investigated. The spacechargedistribution was measured byusing electro-acoustic pulse andtheeffect ofspacecharge on shortcircuit breakdown was analyzed byusingDC pre-stress voltage. Relative crystallinity oftheP crystal inP crystal form polypropylenes was analyzed by usingDSC,and morphology ofthepolypropylenes wasobserved by using POM.Theresults showthattheconventional dielectric properties arealmost same, however thespace chargedensity in: crystal formpolypropylene homopolymerized ismuchsmaller thanthat inthea crystal formpolypropylene homopolymerized, andits decay withtimeismorerapid thanthat intheacrystal formpolypropylene homopolymerized. The:crystal formeffectively inhibits thespace charge effect, which improves space charge induced breakdown.

Fa‐Ming Chen Xiaojun Shen Yu Liao Mingzhong Xu Yan-chang Guo

To understand the changes of schistosomiasis endemic situation and water body security in the Changsha City section of the Xiangjiang River.The prevention and control measures of schistosomiasis, the status of Oncomelania hupensis snails in the marshlands, and the schistosome infection rates of residents on the both sides of the river and boat fishermen were investigated from 2003 to 2012. The schistosome infectivity of the water body was investigate by the method of sentry mice.The snail area decreased from 471 hm(2) in 2003 to 28.81 hm(2) in 2012 with the decline rate of 93.88%. Through the environmental modification, no living snails were found in 9 marshlands among the 11 marshlands, and the density of snails was below 0.006/0.1 m(2) in the other 2 marshlands, but no infected snails were found for 7 years. The original snail habitats of Juzhou scenic area were completely modified and no living snails were found from 2008. In the area, no domestic animals were pastured and the schistosome infectivity of the water body was negative with the sentry mouse method for 10 years. In 2003, the schistosome infection rate was 3.63% in the residents, but no new infections were found in original residents after 2010.The endemic situation of schistosomiasis of the Changsha City section of the Xiangjiang River has reached the standards of schistosomiasis transmission controlled and the water body of Juzhou scenic area is safe.

Abstract Background We investigated the presence of Chlamydia psittaci in poultry and the environment in live poultry wholesale markets in Changsha during 2021–2022 and conducted phylogenetic analysis to understand its distribution in this market. Methods In total, 483 samples were analyzed using real-time polymerase chain reaction and 17 C. psittaci-positive samples using high-throughput sequencing, BLAST similarity, and phylogenetic analysis. Results Twenty two out of 483 poultry and environmental samples were positive for C. psittaci (overall positivity rate: 4.55%) with no difference in positivity rates over 12 months. Chlamydia psittaci was detected at 11 sampling points (overall positivity rate: 27.5%), including chicken, duck, and pigeon/chicken/duck/goose shops, with pigeon shops having the highest positivity rate (46.67%). The highest positivity rates were found in sewage (12.5%), poultry fecal (7.43%), cage swab (6.59%), avian pharyngeal/anorectal swab (3.33%), and air (2.29%) samples. The ompA sequences were identified in two strains of C. psittaci, which were determined to bear genotype B using phylogenetic analysis. Thus, C. psittaci genotype B was detected in the poultry and environmental samples from the poultry wholesale market in Changsha during monitoring. Conclusions Monitoring programs for C. psittaci in live markets need to be strengthened to address the possible zoonotic threat.

The Effect of Crystal Forms on Dielectric Properties of Polypropylene

Hong Zhao Mingzhong Xu Wenlong Zhang Xuan Wang

In the present paper, the dielectric properties of polypropylenes with different crystal forms were investigated. The space charge distribution was measured by using electro-acoustic pulse and the effect of space charge on short circuit breakdown was analyzed by using DC pre-stress voltage. Relative crystallinity of the beta crystal in beta crystal form polypropylenes was analyzed by using DSC, and morphology of the polypropylenes was observed by using POM. The results show that the conventional dielectric properties are almost same, however the space charge density in beta crystal form polypropylene homopolymerized is much smaller than that in the alpha crystal form polypropylene homopolymerized, and its decay with time is more rapid than that in the alpha crystal form polypropylene homopolymerized. The beta crystal form effectively inhibits the space charge effect, which improves space charge induced breakdown
