Q:How to use digital multimeter to detect the quality of 36 volt low voltage lighting transformer?
The number of tables in this table is increasing when the table rings to show 1.Method 2 is only to measure the capacitance is good or bad, can not be measured capacity.
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:How many 40W bulbs can be brought into the 1000VA lighting transformer?
The key is that the 220V terminals and 0 can not provide 1000VA capacity?
Q:The difference between lighting transformers and control transformers
The lighting voltage is 36 and 12V, the signal lamp is 6V, the control winding is 127, 110V, the one or two insulation, and the two one is grounded.Simple lighting transformers, the two voltage is not so diverse.
Q:How many A leakage protection switches are used in 5000VA lighting transformers?
According to the working principle of the protector, it can be divided into three kinds: voltage type, current type and pulse type. The voltage protection device is connected to the transformer neutral point and the ground, when the electric shock when the neutral point voltage offset to the real estate, in order to make the action to protect the power off, but because it is the protection of the transformer low voltage network, cannot be classified protection, so the power range is large, frequent moves, so has been eliminated. The pulse current protector is a sudden change in the phase and amplitude of the three-phase unbalanced leakage current when an electric shock occurs, which is used as an action signal, but also a dead time. The current type current leakage protector is widely used, so the protector of current type is mainly introduced below.
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:What's the function of the lighting transformer?
Illumination transformer: usually refers to the secondary output voltage for the safety voltage 24V - 36V, only for special lighting power supply using voltage converter.
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
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:Power and lighting transformers, lighting quality will be affected much?
Corresponding to the transformer power supply, in order to save costs and reduce costs, the choice of AC ignition method is better. Pure resistive load, the power factor is 1. The 3 *100W=300W is the capacity of the required transformer
