Q:How is the lighting power of the 380V transformer calculated?
Special transformer power transformer (electric furnace transformer, rectifier transformer, power frequency test transformer, voltage regulator, transformer, audio, mine variable frequency transformers, high frequency transformer, transformer, instrument transformer, impact power transformer, reactor, mutual inductor etc.) circuit with T symbol number. For example: T01, T201 etc.
Q:Our power lines and lighting lines are connected to the same transformer. Is there any effect?
As long as the capacity of the transformer is enough, the voltage fluctuation of the line will be sure to occur when the high power equipment is started. Such fluctuations do not have much impact on the lighting.
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:Why is elevator lighting transformer installed?
9.4.5 well distribution shall comply with the following requirements:1 the elevator hoistway shall be dedicated to the elevator, and no equipment, cables and other devices related to the lift shall be installed in the hoistway.2 the well shall be provided with illumination, and the illumination shall not be less than 501x, and shall comply with the following requirements:
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 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:Is the substation separate from the power and illumination transformer?
The power and lighting power supply in the substation need not be separated. In a large capacity power plant, the lighting can be electrically powered to ensure that the generator is stopped. The lighting source is often separated from the lighting transformer and powered by other power supplies.
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
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 strive to be creative and responsive to our customers' needs, which in turn help strengthen our competitive advantage in the global marketplace. We never stop pushing ourselves to be more professional and excellent.
