Q:How to use digital multimeter to detect the quality of 36 volt low voltage lighting transformer?
General digital multimeter has a capacitor (some of the files with a million capacitance test table of Jack, some use pen)
Q:Our power lines and lighting lines are connected to the same transformer. Is there any effect?
Power lines and lighting lines are connected to the same transformer, without affecting the use of a transformer power users, lighting and power are connected together.
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: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 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: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: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: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:Power and lighting transformers, lighting quality will be affected much?
The quality of transformer itself, coupling coefficient, overload capacity, as well as the impact current of the bulb, the cold resistance of the filament and the starting factor at the same time, it is better to choose the 400VA transformer.
Q:What type of low voltage transformer should be adopted for safety lighting power supply?
We have produced many low voltage lighting transformers, such as outdoor waterproof, high-power stage lighting, as well as indoor small power transformers, customer response, but also good! For example, Guangzhou Color Art Lighting Co., Ltd., before them, our reputation is good!
We have a professional factory integrated with design, manufacture, sale and service. "Quality products and customer first" is the key of our success. Our team is willing to create a bright future with baking practitioners together.
