High-safety environment-friendly energy-saving voltage stabilizer

Abstract

The invention discloses a high-safety environment-friendly energy-saving voltage stabilizer, and belongs to the field of voltage stabilizers. A high-safety environment-friendly energy-saving voltage stabilizer comprises a case, a transformer, a carbon brush replacement part and a motor. The transformer is arranged in the case, the carbon brush replacement part and the motor are connected with each other and are arranged on the transformer, and the motor is connected in the case; the carbon brush replacing part comprises a carrying table body, a pair of carbon brush moving elements and a replacing element; the carbon brush moving element comprises a moving groove; the positions of the carbon brushes are additionally arranged, so that the number of the carbon brushes is multiple, then when the first carbon brush works, due to the fact that the carbon brush becomes short along with use, the stroke of downward movement is converted into the distance of movement of the other carbon brush, and after the first carbon brush is completely used, the second carbon brush starts to make contact with a transformer copper coil; therefore, the inspection period of workers is prolonged, and the cost is saved by utilizing a simple mechanical structure.

Description

technical field [0001] The invention relates to the field of voltage stabilizers, more specifically, to a high-safety, environment-friendly and energy-saving voltage stabilizer. Background technique [0002] A voltage regulator is a device that stabilizes the output voltage. The voltage stabilizer is composed of a voltage regulating circuit, a control circuit, and a servo motor. When the input voltage or load changes, the control circuit samples, compares, and amplifies, and then drives the servo motor to rotate to change the position of the carbon brush of the voltage regulator. By automatically adjusting the coil turns ratio, the output voltage is kept stable. [0003] Transformer is a device that uses the principle of electromagnetic induction to change AC voltage. The main components are primary coil, secondary coil and iron core (magnetic core). The main functions are: voltage conversion, current conversion, impedance conversion, isolation, voltage stabilization (magn...

AI Technical Summary

Problems solved by technology

The main functions are: voltage conversion, current conversion, impedance conversion, isolation, voltage stabilization (magnetic saturation transformer), etc. The transformer is an integral part of the voltage stabilizer, and the voltage stabilizer keeps the voltage stable by adjusting the position of the carbon brush. The maintenance of carbon brushes is mostly regular inspection, or the installation of carbon brush length detection devices, but the inspection cycle is very frequent, which is not convenient to save manpower, and the cost of carbon brush length detection devices is too high, which is not economical enough
