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:The difference between lighting transformers and control transformers
In principle and construction, there is no difference between the two.The only difference is that the secondary coil output voltage is different.
Q:Our power lines and lighting lines are connected to the same transformer. Is there any effect?
Connection mode:N circuit breaker is caused by breaker of outlet line of transformer main cabinet.The branch circuit breaker divides the power, the electricity and the lighting power.
Q:Is the substation separate from the power and illumination transformer?
The power and illumination of the substation are all used on a transformer, which is separated by power and lighting by the station screen of this transformer.
Q:Why the 21 lighting transformer must double winding type safety isolating transformers, prohibited the use of autotransformer.
Double winding type safety isolating transformer is provided with two windings respectively as input and output (primary) winding (secondary) winding, and between the two windings are insulated from each other, only through the magnetic connection to the power supply, which is the secondary winding and the earth does not constitute a loop, if the use of additional electrical insulation, it should be safety isolating transformer.
Q:1000 square meters low voltage.36 volts lighting power supply with multiple transformers and wires
You must know the quantity and power of the lamp to determine the transformer
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:Why is elevator lighting transformer installed?
9.4.5 well distribution shall comply with the following requirements:1 the elevator hoistway shall be dedicated to the elevator, and no equipment, cables and other devices related to the lift shall be installed in the hoistway.2 the well shall be provided with illumination, and the illumination shall not be less than 501x, and shall comply with the following requirements:
Q:Why is the two side of the lighting transformer grounded?
Today's lighting products, regardless of the control system or the electronic power system itself, contain many semiconductorsComponents such as rectifier diodes, transistors, integrated circuits, LED, and so on. Semiconductor components are susceptible to staticElectrical damage, the two side of the power transformer grounding, help to produce a variety of factors, high pressure, residual static electricityDrain to avoid static electricity on the main circuit, to ensure product life.
Q:The transformer zero line has broken, has the result to the household illumination circuit?
No, the zero line of the transformer doesn't go through the zero line of the transformer. It is a star connection, and the center point is zero line
