Control Transformer

Control Transformer(Single phase transformer)

The working principle of a transformer is to usePrinciple of Electromagnetic InductionWorking. The transformer has two sets of coils. Primary coil and secondary coil. The secondary coil is located outside the primary coil. When AC power is applied to the primary coil, the transformer core generates an alternating magnetic field, and the secondary coil generates induced electromotive force. The turns ratio of the transformer coil is equal to the voltage ratio.

For example, the primary coil has 500 turns and the secondary coil has 250 turns. When 220V AC power is applied to the primary coil, the secondary voltage is 110V. The transformer can reduce or increase the voltage.

Working principle of control transformer：

An electrical device that uses the principle of electromagnetic induction to transmit electrical energy or signals from one circuit to another is an important component for transmitting electrical energy or signals.

The principle of a transformer is that the coil connected to the power source receives AC energy, which is called the primary winding. The coil connected to the load sends out AC energy, which is called the secondary winding.

The voltage phasor U1, voltage phasor U2, current phasor I1, current phasor I2, electromotive force phasor E1, electromotive force phasor E2, number of turns N1, number of turns N2 of the secondary winding of the primary winding are simultaneously linked once. The phase of the magnetic flux of the secondary winding is φ m, which is called the main magnetic flux.

1、 Scope of application

BK series machine tools (hereinafter referred to as transformers) are suitable for circuits with voltages ranging from 50-60Hz to 500V, and are usually used as power sources for local lighting and indication of machine tool control appliances.

2、 Structural features

BK series transformers can be divided into shell type according to their structure and vertical type according to their installation method.

Usage environment：

The ambient air temperature ranges from -5 ℃ to+40 ℃, with a 24-hour average not exceeding+35 ℃;

The installation location shall not exceed an altitude of 2000M

When the ambient air temperature is+40 ℃, the relative humidity of the atmosphere does not exceed 50%. At lower temperatures, there can be higher relative humidity. The average maximum humidity in the most humid month is 90%, and the average minimum temperature in that month is+25 ℃, taking into account the condensation that occurs on the surface of the product due to temperature changes.
