Main Transformer Online Regenerative Breather with Photovoltaic Conversion Function and Its Control Method

Abstract

The invention relates to a main-transformer type online regenerative breathing device with the photovoltaic conversion and microwave heating functions and a control method of the main-transformer type online regenerative breathing device. The device comprises a microwave heating device, moisture absorption tanks, a three-way tube, a breathing tube and a valve; the microwave heating device is connected to a photovoltaic conversion system. The method comprises the steps that when the fist moisture absorption tank enters the invalid state, the second moisture adsorption tank is switched, and a moisture absorbent in first moisture absorption tank in the invalid state is dried through microwave by the microwave heating device; when the second moisture absorption tank enters the invalid, the first moisture absorption tank is switched, and the second moisture absorption tank is dried, and the same operation is repeated. According to the method, the technology of heating and drying to regenerate by the microwave heating device is utilized, thus the problems of the traditional main-transformer type breathing device that the moisture absorbent is manually replaced in case of saturated moisture absorption and failure, and large potential risk is caused by moving out from a main-transformer type heavy slips protection device during replacing can be solved; the energy consumption is reduced, and the electricity energy can be effectively supplied.

Description

technical field [0001] The invention relates to a main transformer online regenerative respirator with photovoltaic conversion function and a control method thereof. Background technique [0002] When the main transformer is in operation, it will breathe with the outside air through the breathing tube. If there is no respirator installed on the breathing tube, the main transformer will directly inhale the humid air from the outside. Especially in rainy and humid weather, the main transformer is more likely to be damp. The traditional main transformer breathing device is equipped with a color-changing silica gel hygroscopic agent. When the hygroscopic agent becomes saturated with moisture, the staff needs to bring a qualified and dry hygroscopic agent or a hygroscopic tank filled with a qualified hygroscopic agent to the main transformer site for replacement. During the replacement process The breathing tube of the middle main transformer is directly connected with the outsid...

Problems solved by technology

[0005] The purpose of the present invention is to provide a main transformer online regenerative respirator with functions of photovoltaic conversion and microwave heating and its control method, so as to overcome the problems of the traditional main transformer respirator, which need to withdraw from the heavy tile protection when replacing the hygroscopic agent, and have potential safety hazards and the like. When the moisture absorbing tank is removed, the breathing tube of the main transformer is directly connected with the outside atmosphere, so that the breathing airflow of the main transformer directly inhales the external moisture and moisture, resulting in damp defects
