Voltage stabilizer free of electric arc voltage regulation and control method thereof

Abstract

The invention discloses a voltage stabilizer free of electric arc voltage regulation. The voltage stabilizer comprises a single chip microcomputer processor, a voltage detecting module, an output regulating relay group, a voltage regulating relay converter module, a power supply module, and a transformer, wherein the voltage regulating relay converter module comprises electric supply controllable silicon driven by an output signal of the single chip microcomputer processor, output controllable silicon and a converter relay; an input end of the transformer is accessed to electric supply, and an output end of the transformer is used as an output end of a live wire of the voltage stabilizer. By improving the original transformer switching mode, the product disclosed by the invention is combined with the relay through the controllable silicon, the function of the voltage stabilizer is realized by switching between the transformer output and the electric supply bypass, and the generation of electric arc is reduced and even avoided, so that the power of the voltage stabilizer is remarkably improved, the service life of the relay is greatly prolonged, and the whole-machine service time is guaranteed very well.

Description

technical field [0001] The invention relates to a voltage stabilizer, in particular to a voltage regulator without arc voltage regulation and a control method thereof. Background technique [0002] As we all know, the normal operation of the air conditioner requires a stable voltage, which is generally 187-250V. Below 187V or above 250V, the compressor will stop to avoid damage. For some old compressors without stall protection function, too low or too high voltage will cause damage to the compressor. [0003] The reality is that in less developed regions of the world, such as Africa and South Asia, the voltage is often unstable. During the peak period of electricity consumption, the voltage is as low as 140V, or even 100V, and sometimes as high as 280V during non-peak periods. As a result, the air conditioner cannot function properly. [0004] The solution is to use a voltage regulator. There are two more common ones. One is a relay voltage regulator, and the other is ...

Problems solved by technology

This method can be used for a long time when the power is small, but after all, the relay is a mechanical opening and closing, and a certain amount of arc will be generated between the opening and closing of the relay in a non-absolute vacuum state. However, the general relay cannot guarantee an absolute vacuum state. Over time, the surface of the relay contacts will be oxidized and blackened. Once the contacts are oxidized and blackened, the current passing through the relay will increase, and more and more arcs will be generated, entering a vicious circle.

Eventually, the relay switch will be bonded, so that the relay switch will fail, the voltage regulator will burn out, and even damage the target electrical appliance
