Q: What transformer can be used in a safety voltage lighting transformer?: An isolated transformer is a transformer that is electrically isolated from an input winding and an output winding. The isolated transformer is used to avoid accidental touching of the charged body at the same time, and the isolation of the transformer is to isolate the current of the former side winding coil.

Q: How many can you bring with 220V? How many can you bring with 380V? There are 3 terminals on the transformer. There are 220V, 380V, 0, three terminals. 220V is the 220V terminal and the 0 connection. How can the 380V be connected? Is it 380V and 0 or 380V and 220V?: Voltage x current = power, in general we are using the total power of 2/3, you can press this type of calculation, if the installation of electrodeless lights, the line should be separated,

Q: What type of low voltage transformer should be adopted for safety lighting power supply?: In general, indoor transformers are used in general practice

Q: Why is the two side of the lighting transformer grounded?: Single-phase transformer two side lighting to the ground, on the one hand is the lighting products now contain many semiconductor devices such as diodes, transistors, integrated circuits, semiconductor devices vulnerable to electrostatic damage, two side grounding contributes to the surge pressure factors produced by residual electrostatic discharge stay in the main circuit, avoid electrostatic protection, product life. In the 21 aspect, there is distributed capacitance between the two side and the primary side of the power transformer, and the high frequency surge disturbance caused by the primary side current source will directly enter the two side to the main circuit through the distributed capacitor. These unnecessary high frequency interference may jump into the sensitive signal source, make the control system malfunction, and the two side grounding of the power transformer can eliminate most of the undesirable effects of the distributed capacitance.

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: 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: Why the 21 lighting transformer must double winding type safety isolating transformers, prohibited the use of autotransformer.: The self winding transformer is connected by all its windings, and depends on the position of the sliding contacts to change the magnitude of the voltage. Therefore, there is not only a magnetic connection between the primary winding of the autotransformer (the power circuit) and the two winding (the power supply circuit), but also the direct connection of the circuit. It forms a circuit with the earth, so it can not be used as the power source of the safety voltage

Q: Can the 500 volt lighting transformer be changed into an electric welder?: The no-load voltage is higher (about 70~90 V), the arc can be smoothly started, and the voltage will be reduced to about 30 V when welding.

Q: Please tell me how to calculate the transformer in the lighting circuit of elevator shaft in building electrical design: Because of the brightness of the 36V safety voltage lamp brightness in the overhaul work is not enough, so now the well lighting design should not be 36V, and replaced by 220V, and only need to add a leakage protector on it.

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.
