Q: Who knows how big transformers and lines the 36V transformer uses in lighting?: No matter how many volts the output / input voltage of the transformer is, the size and the amount of the core of the transformer, the wire diameter of the winding lead and the lead thickness must be determined by the transformer capacity. Example: input 220V, output 36V load is 36v/40w light bulb 6, so the primary needs 0.72, secondary use 1.81 diameter enameled wire winding system. The transformer capacity is about 250VA.

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: How to use digital multimeter to detect the quality of 36 volt low voltage lighting transformer?: If there is no painting can be used with a diode symbol file (measuring probe connected to the capacitor to hear a sound if the table does not ring at the table and then the general display is 1, then the pen on the emergence of the phenomenon that the capacitance is still good. If one table has been ringing that received the capacitor capacitor breakdown is broken)

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: The transformer zero line has broken, has the result to the household illumination circuit?: The zero line is connected to the transformer neutral point of transformer, three FireWire for its voltage is 220 volts, according to regulations, the total can not take the zero line fuse, switch, because once the zero line is disconnected, the rest of the line will no longer be a neutral line, into the use of electrical appliances connected to two the conductor, according to the characteristics of series circuit, each phase with electrical voltage, on load distribution, change the original load smaller which phase by using electrical appliances, will damage due to excessive voltage.

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 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: 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: Which is more energy saving by using 24V500W transformer lighting and 220V500W lighting?: See whether the lamp power saving, can not see whether it has a transformer, but to see the light efficiency of the lamp, that is, the ratio of light flux to power!Popular speaking, that is, spend the same electricity to see who sends more light!So, when comparing, ask what the light is, then judge again!The luminous efficiency unit is LM/W

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.
