Problems solved by technology

[0006] In the prior art, when replacing the failed color-changing silica gel, it is necessary to apply to the dispatcher for a power outage operation, and the whole process consumes a lot of time and labor costs
At the same time, the replacement of silica gel for the transformer in operation also has the risk of causing heavy gas protection action

Embodiment Construction

[0048] The preferred embodiments of the present invention will be described below in conjunction with the accompanying drawings. It should be understood that the preferred embodiments described here are only used to illustrate and explain the present invention, and are not intended to limit the present invention.

[0049] like figure 1 As shown, the transformer respirator in the prior art is a single drying tank, and the internal desiccant silica gel cannot be automatically regenerated. The main components of the prior art respirator are: a glass cover (silica gel desiccant is housed), a glass cylinder, air holes between cups, an oil collecting cup, air holes, and an interface flange of the respirator.

[0050] In the prior art, after the respirator has been in operation for a period of time, due to the continuous absorption of moisture in the air entering the transformer, the moisture absorption capacity of the color-changing silica gel gradually weakens until it fails. replac...

Abstract

The invention discloses a respirator system and a switching method, and the respirator system switching method comprises the steps: collecting humidity data in a third air channel; if the humidity data exceeds a first preset threshold value, starting an electromagnetic valve, and switching communication between a third gas path channel and the first gas path channel into communication between thethird gas path channel and the second gas path channel; starting a first heater for heating, and starting first timing; and after the first timing is finished, closing the electromagnetic valve, and switching the communication between the third gas path channel and the second gas path channel into the communication between the third gas path channel and the first gas path channel. Automatic switching of the respirator drying tank can be achieved, regular replacement of silica gel is not needed, and the respirator maintenance work efficiency is improved.

Description

technical field [0001] The invention relates to the field of electric power technology, in particular to a respirator system and a switching method for an oil-immersed power transformer. Background technique [0002] The existing transformer is one of the most important equipment in the power system as the power equipment for transforming, transmitting and distributing electric energy in the power system, and is crucial to the safe operation of the power system. Moisture content in oil-immersed transformers is an important indicator that affects the aging speed and insulation performance of transformer insulating oil and insulating paper. In order to ensure the insulation level of the oil-paper insulation system inside the transformer, the moisture content inside the transformer must be controlled at a reasonable level. The horizontal range; and the respirator (also called a moisture absorber) is an important safety component to ensure this indicator. [0003] The respirato...
