Abstract

The invention discloses a voltage stabilizer, and relates to electronic equipment. The voltage stabilizer comprises a cabinet body which is internally provided with an equipment cavity, an electricalcomponent is sealingly arranged in the equipment cavity, a hollow interlayer is arranged between the cabinet body and the equipment cavity, a gas circulation device is arranged on the cabinet body, and comprises an air pump and an air storage tank, compressed nitrogen gas is stored in the air storage tank, an air inlet and an air outlet which cooperate with the air circulation device are formed inthe equipment cavity, a heat exchange device is arranged on the air circulation device, and comprises a water tank arranged in the hollow interlayer, and a pipeline of the gas circulation device passes through the water tank. The voltage stabilizer is sealingly stored in the cabinet body full of nitrogen gas, outside dust and impurities are isolated, and meanwhile the interior of the cabinet bodyhas constant temperature and constant humidity; due to the fact that contact of oxygen does not exist, an oxidation reaction is eradicated, the service life of the voltage stabilizer is greatly prolonged, and the failure occurrence rate is lowered.

Description

technical field [0001] The invention relates to an electric device, especially a 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. In the hot summer in the south, the ambient temperature is high, and the voltage stabilizer under high load will heat itself seriously, and will run above the warning temperature for a long time, which will not only reduce the service life of the transformer, but also cause unimaginable consequences in case of danger. At this time, it is impossible for the voltage regulator to reduce the po...
