The BK transformer is a new type of transformer supply developed by my country in China. It has the characteristics of small size, safe and reliable wiring, high protection level, good performance, etc., and can work effective in the rated load for a long time.BK transformers can be divided into shell according to the structure, and the installation method can be divided into vertical formula.Commonly used as a power supply for machine tool control electrical appliances or local lighting and indicator lights.
BK transformer parameter
1. The rated voltage rated voltage is divided into a primary rated voltage and a secondary rated voltage.The primary rated voltage refers to the effective value of the primary voltage specified by the transformer based on the insulation strength of the transformer under the rated working conditions.For the power transformer, it usually refers to the power supply voltage added to the primary winding of the transformer in accordance with regulations.The secondary rated voltage refers to the valid value of the secondary output voltage when the primary adding the rated voltage and the secondary air load.2. When the rated current is the rated voltage, the current winding of the primary winding can be normal and the secondary winding can be output normally, which are called primary and secondary rated currents, respectively.3. The rated capacity of the rated capacity transformer refers to the output capacity of the transformer under the rated working conditions.For high -power transformers, it can be represented by the rated voltage of the secondary winding and the multiplication of the rated current.For small -power power transformers, due to different work conditions, the primary and secondary capacity should be calculated separately.4. The rated frequency rated frequency refers to the voltage frequency value of the normal operation of the transformer.Under normal circumstances, the rated frequency is 5oHz.When required, you can design a transformer at 40oHz, IKHZ, LOKHZ and other frequencies.

What is the BK transformer
The BK transformer is the model BK, suitable for 50 to 60Hz, and the applicable voltage in the circuit within the range of 500, is usually used for transformer control or local lighting.This transformer is made of lacquer bags with high temperature resistance and silicon steel sheets with relatively high temperature strength.The transformer of the BK series is an egg shell -like manifestation in the form of an iron heart. It is made of silicon steel sheets.The BK transformer is suitable for the power supply used in large industrial and mining enterprises for local lighting. Among those electrical equipment, the role of control circuit and signal light indicator light is played.This BK transformer needs to be before the surrounding air humidity is minus 5 degrees to the maximum temperature of 40 degrees, and the average temperature of the 24 -hour temperature cannot exceed 35 degrees, and the contrast cannot be too large.The location installed at an altitude cannot exceed 2,000 meters.It is not suitable for installation in places where severe vibrations and impact vibrations, and it is not suitable to be installed in places where rain and snow are often invaded. It is necessary to install the voltage wave close to sine waves.It is not possible to corrode metal and destroy insulation in the dangerous environment of explosion.
