Q:Which is more energy saving by using 24V500W transformer lighting and 220V500W lighting?: If the transformer is not calculated, the loss is the same. If the calculation is the latter, save electricity.

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:The transformer zero line has broken, has the result to the household illumination circuit?: The lighting circuit mostly 3 phase unbalanced load, there will be zero drift, zero if the transformer line is broken, part of the lighting circuit to form a series of equipment in the case of two-phase circuit, circuit voltage is decreased and the lighting brightness is not enough, circuit voltage increases, the lamp burned;

Q:Please tell me how to calculate the transformer in the lighting circuit of elevator shaft in building electrical design: Pe=19.5KW, installed capacityKx=1 coefficient of demandPjs=KxPe=19.5KW, calculated loadCOS, phi, =0.85, power factorIjs=KxPe/3/220/cos phi (Ijs calculates current, voltage, 380V/220V, three-phase)=1*19.5*1000/3/220/0.85=34.76A

Q:Why the 21 lighting transformer must double winding type safety isolating transformers, prohibited the use of autotransformer.: A set of coils in a autotransformer having one tap that does not function as a barrier. Or, the two sets of coils are attached.

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:What transformer can be used in a safety voltage lighting transformer?: 220V/36V or 24V isolation transformer. Double winding, high and low voltage coils, not connected.

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:1000 square meters low voltage.36 volts lighting power supply with multiple transformers and wires: To 30VA/ square meters, the transformer needs 30KVA, with two 120 square copper wire. Specific should be used to determine the total power of the lighting transformer.

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?: The key is that the 220V terminals and 0 can not provide 1000VA capacity?
