hotel engineering lamps and lanterns of wholesalers, professional wholesale sales or customize the Chinese style and European style hotel engineering lamps and lanterns, is a local supplier of lamps and lanterns with tremendous strength, welcome the masses of customer cooperation.
hotel engineering lamps and lanterns of test of the four methods:
( A) Withstand voltage test ( Routine test) :
1。 According to the hotel engineering lamps and lanterns of regional standard first debugging good corresponding voltage and leakage current; Then at the end of the compression machine wire even in the lamps and lanterns for the positive & lt; Switch is open & gt; And then the conductance of the pressure machine the other end of the wire connection gun & lt; Or conductive rods & gt; Open to the outside metal parts of lamps and lanterns hit 1 seconds, if no sound pressure machine the lamps and lanterns is the power cord through the test; Leakage or conversely breakdown.
2。 Using the same method to test the negative power cord hotel engineering lamps and lanterns, pay attention to the personal safety operation under the control of contact is not actually dangerous) 。
( 2) Hotel engineering lamps and lanterns of on-off test ( Routine test) :
1。 Screw the bulb in the socket connection cord start switch test.
2。 Connect the power cord, with pressure machine end at the other end contact lamp holder corresponding pole & lt; Among general lamp holder metal for the positive side of metal for negative & gt; If pressure machine sounding for access to the opposite of open circuit.
3。 Also can use the multimeter to test, the method with B, if meaning: is used to indicate the corresponding time of a clock swing pathway, conversely for open circuit.
( 3) Hotel engineering lamps and lanterns of polarity test & lt; Commonly used in lamps and lanterns of ul & gt; ( Routine test) Polarity to distinguish: single power cord: black is positive; White as the cathode. There two core power cord: a is positive; Not a negative word. Polarity plug: capitulum is positive; Big head for the cathode. Lamp holder: the middle metal anode; The side metal as the cathode. Using the multimeter, contact the power cord or plug the cathode, the cathode end multimeter, the positive side contact lamp holder negative, needle moving right; Vice error.
( 4) Hotel engineering lamps and lanterns of grounding test ( Routine test) :
1。 你们; General export & gt; : turn the grounding device range for 10 a grounding device wire clip on the ground, Nickname: ground wire) Metal parts; Lamps and lanterns of wires at the other end conductance shooting to use metal parts. If resistance less than 100 m Ω qualified & lt; If qualified grounding device emits sound & gt; , the opposite is not qualified.
2。 你们; General sale in domestic market & gt; : turn the grounding device range is 25. A method as above. If the resistance is less than 500 m Ω qualified; The opposite is unqualified.
the above is the professional testing methods, mainly to share some little knowledge on the subject, let us have a more profound understanding of lamps and lanterns for hotel engineering.
