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:How many A leakage protection switches are used in 5000VA lighting transformers?
It is widely used in the electronic industry or industrial and mining enterprises, in the machine tool and the mechanical equipment, the control power of the general electric circuit, the use of the power supply of the safety lighting indicator lamp.
Q:How to calculate the rated capacity of small transformers for lighting purposes?
Capacity of power transformer is the basic equipment for a total capacity of [kW] (maximum power consumption rate by a / X100 capacity) divided by the power load [%] value for benchmarking.
Q:The transformer zero line has broken, has the result to the household illumination circuit?
The power supply system in three-phase four line zero line is broken, the breakpoint of the single-phase circuit (220V) electrical burn by voltage to 380V. I met, the incandescent lamp suddenly particularly bright then the blow up of internal fuse TV has burned out. So in the three-phase four wire power supply system zero line asked to do repeat grounding in households is the reason.
Q:How many 40W bulbs can be brought into the 1000VA lighting transformer?
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: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!
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:What's the function of the lighting transformer?
Illumination transformer: usually refers to the secondary output voltage for the safety voltage 24V - 36V, only for special lighting power supply using voltage converter.
Q:What transformer can be used in a safety voltage lighting transformer?
Early European countries used in the power industry, widely used in the electronic industry or industrial and mining enterprises, machine tools and machinery equipment general circuit control power supply, safety lighting and indicator light power supply.
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
