Electrical shielding electrothermal tap

Номер: CN0002299275Y
Автор: SUN XUETANG, SUN JIXIN, XUETANG SUN, JIXIN SUN
Принадлежит: SUN XUETANG

The utility model relates to an electrothermal tap which heats the water by the 220V alternating current or the 380V alternating current. The utility model heats the water not by a heating wire which is sealed in a water insulation metal tube. The utility model discloses an electrical shielding electrothermal tap, composed of an inner column rod pole made of a section of stainless steel rod and an outer cover tube pole made of a section of stainless steel tube. The inner column rod pole is always connected with the fire wire of a supply and the outer cover tube pole is always connected with the earth wire of the supply, which can be ensured by an alternating current contactor or a recognizing plug which can show the fire wire and the earth wire of the supply. So the fire wire potential of the inner column rod pole can be tightly shielded by the earth wire zero potential of the outer cover tube pole. When immersed in water, the utility model can safely heat the water with less energy. When ...

The embodiment of the invention provides a method for measuring the content of oil stains in iron oxide chips, and relates to the field of measurement of the content of oil stains in iron oxide chips. The problem that the oil content value in the iron oxide chips cannot be accurately detected is solved. The method comprises the following steps: drying a sample in a sample containing plate for a first time period at a first preset temperature to obtain a first-stage sample with constant moisture weight; drying the first-stage sample in the sample containing plate for a second time period under the condition of a second preset temperature to obtain a second-stage sample; and drying the second-stage sample in the sample containing plate at a third preset temperature for a third time period, and raising the drying temperature to a fourth preset temperature for a fourth time period. The moisture is detected in the first stage, the sample with the moisture detected is gradually heated and dried ...

High-efficiency fluorescent lamp tube with long service life

Номер: CN0102087950A
Автор: SUN XUETANG, SUN JIXIN, XUETANG SUN, JIXIN SUN
Принадлежит:

The invention relates to a high-efficiency fluorescent lamp tube with a long service life, wherein the electrode of the lamp tube cannot be destroyed. In a fluorescent lamp tube shell, a thin metal column plate electrode and a column plate electrode lead, which are bent back at both ends of the lamp tube, are electrically connected through a lead; and low-pressure mercury steam is encapsulated in the fluorescent lamp tube shell. When the produced fluorescent lamp tube is connected into an electronic ballast (in which a capacitor is usually accommodated and connected) connected with a power supply, the fluorescent lamp tube can emit light in a high efficiency and long service life way.
