TB512-050.0M

Oscillators are widely used in various types of electronic circuits in physics, communications engineering, computers, and other fields. This article focuses on the TB512-050.0M oscillator and its application field and working principle.

The TB512-050.0M oscillator is a sine wave oscillator composed of four commonly used parts: source resistance, bimorph bridge, upper frequency compensation capacitor, and multivibrator circuit. Its oscillation frequency is in the 50--512KHz range, mainly used for earth fault protection devices. This oscillator is particularly suitable for avoiding instability caused by the random noise.

In terms of the working principle, when the multivibrator circuit generates a sinusoidal signal, the resistance, bimorph bridge, and capacitor form an LC oscillatory circuit, which produces vibrations at a certain frequency. The multivibrator circuit can achieve automatic frequency adjustment by changing the bridge current of the bimorph bridge.

The TB512-050.0M oscillator can be used in various applications. For example, in the field of electric power, it can be used for voltage and current quantitative protection devices, distance protection devices, local trip protection devices, and logic protection devices. In addition, the TB512-050.0M oscillator can also be applied in environmental protection areas. For example, it can be used in anti-explosion, anti-corrosion, and fire alarm systems.

To sum up, the TB512-050.0M oscillator is a widely used oscillator in various kinds of electronic circuits. Its application fields include electric power, environmental protection, etc. Its working principle is based on the oscillatory LC circuit and the multivibrator circuit, which can achieve automatic frequency adjustment.
