Output voltage accuracy
1-5%(can be adjusted)Frequency:50HZ/60HZ
≥98%(Power grade over 50KVA)
The voltage for electrical strength and power frequency sinusoidal is 2000V without breakdown and flash over when lasts 1minute
It can last 1 minute at the rated current of two times
Wave form Distortion
No additional waveform distortion
it offers the protections against over voltage,over current,phase shortage and phase-sequence(The single-phase offers no protection against the phase shortage and phase-sequence)and mechanical failure
≤1s(in the condition that the external voltage changes is 10%)
- 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:What type of low voltage transformer should be adopted for safety lighting power supply?
- In general, indoor transformers are used in general practice
- Q:Is the substation separate from the power and illumination transformer?
- The power and illumination of the substation are all used on a transformer, which is separated by power and lighting by the station screen of this transformer.
- Q:Our power lines and lighting lines are connected to the same transformer. Is there any effect?
- It is not easy to control, the power and lighting and electricity; if the transformer capacity is small, and relatively large power equipment start frequently, voltage stability will be poor, the lamp brightness will fluctuate dramatically, have effect on visual acuity. But as long as the design is reasonable, it has little effect.
- Q:How many power illuminator can 5Kva 36V transformer drive?
- By formula: P=UI COSAThat is, the transformer capacity is S=UI=5KVAHow big is the COSA?. Look, what kind of illuminator do you use?. Usually take 0.8-0.9It can be calculated that P is about 4KW-4.5KW (general lighting)
- Q:Lighting, lights, transformers, bulb brightness is too low, what's the matter?
- Line light for safety light, voltage 24 volts and 36 volts, pay attention to the bulb and transformer voltage matching.
- Q:The difference between lighting transformers and control transformers
- A control transformer is a low voltage appliance, usually used as a power supply or part of a lighting for the control of electrical equipment such as machine tools. There are usually two different voltage outputs,
- Q:How many 40W bulbs can be brought into the 1000VA lighting transformer?
- Now is the three standard power supply, fire, fire and a single, zero line is three 220V, the fire is 380V. 40W lights can be 25.
- 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: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
