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:1000 square meters low voltage.36 volts lighting power supply with multiple transformers and wires
First of all, make sure your power is too large, but you are not recommended to do so, the cost is too high, the pressure drop is too large, you can raise the voltage to 220V or higher, and then transfer to avoid power losses. If the direct transmission, the power is slightly larger, the line will be very rough, the cost will be very high
Q:Who knows how big transformers and lines the 36V transformer uses in lighting?
380V-220V/36V transformers, commonly known as safety transformers or line transformers, are mainly used for lighting in shop equipment and mobile lighting for inspection and maintenance. Their power is 50W, 100W, 200W, 300W., and their line size is determined by power!
Q:Why should lighting transformers be used in factories and mines?
In some factories and mines (such as power plants), in order to supply power reliability, the power system is grounded in a three-phase, ungrounded, or neutral manner. In this way, the transformer must be connected to a neutral grounding type with a special transformer to supply power to the lighting.
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:Why is elevator lighting transformer installed?
1) a lamp shall be installed at the highest and lowest point 0.5m away from the hoistway, and a light shall be installed at intervals not exceeding 7m, and a control switch shall be installed in the engine room and the bottom pit respectively;2) the lighting power supply for car top and hoistway shall be 36V; when 220V is adopted, the residual current action protector shall be installed;3) there is no lighting device for a closed well road with sufficient lighting conditions around the hoistway.
Q:Why can't autotransformer be used as transformer for safety lighting?
The transformer of the lighting circuit is a step-down transformer (general input 10kv., 220V). The first coil of the autotransformer is shared and connected together
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 calculate the rated capacity of small transformers for lighting purposes?
But in fact, consider the total load, the importance, the location of the machine, and the future additional plan, according to the following order.
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
