Q:Which is more energy saving by using 24V500W transformer lighting and 220V500W lighting?: 220V500W more power saving:Reasons: 1, high voltage, small current, line loss is small; 2, reduce the transformer and other intermediate links, each link has a loss.

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:The transformer zero line has broken, has the result to the household illumination circuit?: When the zero line break line is not broken, the voltage drift of the point voltage leads to the rise of the 220V branch voltage and the reduction of the 220V branch voltage

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:Why should lighting transformers be used in factories and mines?: But in many cases, such as mines and machinery, the voltage is too high and unsafe. The lighting transformer is then used to reduce the voltage to the so-called "safety voltage""

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:What's the function of the lighting transformer?: Applies to some requirements for safe voltage 24V - 36V lighting sites. Such as: basement, tunnel, dangerous goods warehouse and so on. Then there is the (mobile, temporary) safety lighting for the overhaul.

Q:Why is elevator lighting transformer installed?: 3 a power outlet shall be provided at the bottom pit.4 the cables and wires laid in the hoistway shall be flame retardant and damp resistant, and shall be protected by a nonflammable wire, conduit, or wire slot, with no use of wires, conduits, or wire slots made of combustible material.5 an elevator attached to a building whose wiring, materials and methods and electrical components used shall take into account the effects of climatic conditions and shall take waterproof measures.Lighting transformers in order to obtain 36V voltage

Q:How to calculate the rated capacity of small transformers for lighting purposes?: If the flow of large capacity motor starting current and welding machine, large current flows in a short period of time in the load even when the power equipment capacity can withstand current flow in a short time, but due to a voltage drop excitation electromagnetic switch relief, the motor can not start, damaged or the undesirable phenomenon of welding. Therefore, the voltage drop rate should be calculated as less than 10% of the supply voltage, as calculated below.

Q:Why can't autotransformer be used as transformer for safety lighting?: When a fault occurs, leakage of electric leakage occurs, and the original coil is transmitted to the residents at high voltage, causing disastrous effects on the human body and property!
