Description

Technical Field

The utility model relates to a voltage-stabilized power supply, in particular to a vibration-damping voltage-stabilized power supply used for railways.

Background Art

A voltage-stabilized power supply is a power supply device that can convert AC power into DC power and stabilize the voltage. It is widely used in places such as railways, construction sites, and factories that require a stable power supply voltage. The main function of a voltage-stabilized power supply is to convert unstable AC power into stable DC power to ensure the normal operation of the equipment. In electronic equipment, due to external power supply voltage fluctuations, load changes, and other reasons, the output voltage will become unstable, thus affecting the normal operation of the equipment.

The voltage stabilizer used for railways has a large load capacity and poor heat dissipation effect. In addition, the railway transportation environment in which the voltage stabilizer is located is relatively harsh, which is manifested in that it is easy to shake and collide, and needs to be frequently used. The existing protection measures for railway voltage stabilizers mostly adopt the installation of anti-seismic brackets, the addition of shock-absorbing support devices, etc. The brackets have a rigid structure, the shock-absorbing effect is not ideal and it is not easy to carry, and it cannot effectively reduce the shock and protect the equipment.
