Q:How to use digital multimeter to detect the quality of 36 volt low voltage lighting transformer?
General digital multimeter has a capacitor (some of the files with a million capacitance test table of Jack, some use pen)
Q:Why should lighting transformers be used in factories and mines?
There are two cases. One is the general factories and mines, and the low voltage is three-phase four wire system, and the neutral point is directly grounded. Between the phase line and the zero line is 220V, which can be connected with the illumination load.
Q:3 24V100W lights, I need to use a large capacity transformer (220V change 24V)?
First look at this lamp,.24V100W, this specification is common in the headlights of large trucks, filled with inert gas, known as the small sunThe power supply comes from the generator or battery, and the mode of operation is to ignite by alternating current and direct current. In comparison with the power supply of the transformer, the method of alternating current ignition is better to save the cost and reduce the cost
Q:Lighting, lights, transformers, bulb brightness is too low, what's the matter?
Generally, the power of the transformer is the apparent power, and the light bulb is the active power, and the power matching is taken into account.
Q:Line lights, lighting transformers in use!! Can live line work?!! Be afraid of electric shock 40
I don't know how much the output voltage of your transformer is, but the internationally accepted voltage below 36V is the voltage that is not harmful to the human body
Q:Why can't autotransformer be used as transformer for safety lighting?
When a fault occurs, leakage of electric leakage occurs, and the original coil is transmitted to the residents at high voltage, causing disastrous effects on the human body and property!
Q:Is the substation separate from the power and illumination transformer?
There is only bus in the substation, and the station is connected with the transformer from the bus. If there is no electricity even in the bus, then the substation should not be considered active.
Q:Why the 21 lighting transformer must double winding type safety isolating transformers, prohibited the use of autotransformer.
A set of coils in a autotransformer having one tap that does not function as a barrier. Or, the two sets of coils are attached.
Q:Can the 500 volt lighting transformer be changed into an electric welder?
500 VA transformer should not be used as an electric welding machine, so it is very difficult to reform the system, so it is better to buy a new electric welder
Q:Please tell me how to calculate the transformer in the lighting circuit of elevator shaft in building electrical design
The previous elevator hoistway lighting required the 36V safety voltage, and you can see how many power lamps are required for the hoistway, and select the transformer
