2000kv/10a, three-stage reactors stacked system
Overview This device is designed and manufactured for 35kV cable AC withstand voltage test. The reactor is individually designed for multiple units, which can not only meet the test conditions of high-voltage and low-current equipment, but also meet the low-voltage AC withstand voltage test requirements of 10kV cables. The special AC resonance test system for cables adopts the method of adjusting the frequency of the power supply, so that the reactor and the capacitor under test can achieve resonance, and the high voltage and large current can be obtained on the test product. It is a new method of current high voltage test and The trend has been widely used at home and abroad. The AC resonance test system uses a dedicated SPWM digital waveform generator chip with a frequency resolution of 16 bits, and the frequency fineness can reach 0.1 Hz at 20 to 300 Hz; it adopts an orthogonal non-synchronous fixed carrier modulation method to ensure that the entire frequency The output waveform is good in the interval; the advanced IPM module is used in the power part to ensure the stability and safety of the instrument under the minimum weight. The test system consists of a frequency and voltage regulation power supply, an excitation transformer, a reactor, and a capacitor divider. Technical index 1. the resonant excitation power supply only needs 1/Q of test capacity, which is 1/10-1/30 of common test unit and reduces the system weight and volume greatly. 2. Rated voltage: 1.108kV meeting the alternating current withstand voltage test for 35kV cable; 2.Waveform distortion rate of output voltage should be less than 1.0 3.The permissible continuous working time is to work for 5 minutes at one time under rated condition. 4.Quality factor of unit itself: Q 50 Advantage 1.The power capacity needed is reduced greatly. 2.The weight and volume of equipment is reduced greatly. 3.The waveform of output voltage is improved. 4.The large short-circuit current is prevented from burning fault point. Feature: 1. A large number of cables with voltage levels of 35kV and below are used, and the test workload is large, so this type of withstand voltage test device is small in size and light in weight, and a portable cable withstand voltage test system was born; 2. This system requires that the weight of the parts that a single person can move on-site does not exceed 30kg, and the weight of the parts that two people can move on-site does not exceed 60kg, which is suitable for on-site transportation; 3. The power supply adopts 220V single-phase power supply or 380V single-phase power supply, which is convenient for on-site power supply; 4. The reactor part is made of dry epoxy casting, which is beautiful and reliable, suitable for the requirements of various cables; 5. The withstand voltage test of 110kV and above cables adopts oil-immersed reactors.

SENNA PODS Senna has been used as a traditional medicine by ancient cultures all over the world for millennia. Senna is an Arabian name and 9th century writings describe how it was used extensively by Arabian physicians. According to a rare Egyptian medical papyrus, dating to the 16th century BCE, Senna was prescribed by the physicians for their distinguished patients. In North America, native tribes used the seeds (pods) as a mucilaginous medicine for sore throat. The Cherokees used the bruised root, moistened with water, for dressing sores. They also used it in a tea to cure fevers with black spots and paralysis as symptoms. Senna Pods Uses: Taking senna by mouth is effective for short-term treatment of constipation. Senna is an FDA-approved nonprescription drug for adults and children ages 2 years and older. However, in children ages 3-15 years, mineral oil and a medication called lactulose might be more effective than taking senna. Senna also appears to be effective for treating constipation when used in combination with psyllium or docusate sodium. In elderly people, senna plus psyllium is more effective than lactulose for treating ongoing constipation. Senna plus docusate sodium is effective for treating constipation in the elderly and in people who have undergone anorectal surgery. Taking senna appears to be as effective as lactulose, psyllium, and docusate for relieving constipation in people taking opioids or loperamide. Senna Benefits Constipation The most famous use of this herb is as a laxative and a purgative. It is now known that the laxative effects of Senna are due to anthraquinone glycosides known as sennosides. These compounds stimulate intestinal contractions that lead to the rapid expulsion of waste matter. Senna may also be able to soften the stool by assisting the large intestine to absorb more water and adding bulk to faeces. This allows for bowel movements that are quick and smooth as waste passes through the large intestine. Colon Cleanse Senna is often used to clear the bowel before diagnostic tests such as colonoscopies. Cleansing the colon is believed to improve nutrient uptake and support overall colon health. Anti-Parasitic:Senna also works as an effective vermifuge to destroy parasites and expel worms from the intestinal tract. It works best when combined with other anthelmintic herbs (used in the treatment of roundworm), such as ginger or fennel. These herbs increase regularity and reduce the chance of bowel cramps due to Sennaâ??s strong action. Digestive Health In the case of indigestion, Senna contains natural enzymes that help to restore gastric juice secretions in the stomach. Senna, if used in the proper dosage for certain periods of time, has shown potential in reducing irritability in the intestines by improving overall digestion. Senna also contains the anti-inflammatory compound resveratrol which can help to soothe inflammation in the gastrointestinal tract. Skin Health
