Testing method and instrument of multipoint earthing slide-variable resistance of common circuit

Номер: CN0101963642A
Принадлежит:

The invention discloses testing method and instrument of multipoint earthing slide-variable resistance of a common circuit. The testing method comprises the following steps of: breaking the earthing point of the tested N wire by connecting a slide-variable resistor and an alternating-current ampere meter between the tested N wire and the earthing point to change the resistance value of the slide-variable resistor; and judging whether multipoint earthing exists in the common circuit or not by collecting the current value of the alternating-current ampere meter, wherein the current value changes along with the resistance value of the slide-variable resistor. The testing instrument of multipoint earthing slide-variable resistance of the common circuit can directly detect whether multipoint earthing exists in the common circuit or not, thereby having simple and convenient operation, friendly and visual interface. The testing method and instrument can be widely applied to the operation and detection ...

Portable smoke purifier

Номер: CN104289060A
Принадлежит:

The invention discloses a portable smoke purifier, which comprises an air intake diversion front cover, a main casing, an atomizer, a filtrate case, an oil mist mixing space, a filtering structure and a blower fan. The air intake diversion front cover, the oil mist mixing space, the filtering structure and the blower fan are communicated; a liquid is introduced in the atomizer from the filtrate case, the atomized liquid is distributed to the oil mist mixing space by the atomizer; the blower fan absorbs the oil smoke to the oil mist mixing space from the air intake diversion front cover, and the atomized oil smoke mixed with a liquid phase is absorbed to the filtering structure from the oil mist mixing space and then is filtered. Comparing with the traditional oil smoke removing equipment, the portable smoke purifier has the advantages of small size, convenient movement and low energy consumption, and can be placed in an indoor area which is difficulty covered by the traditional oil smoke ...
