Main transformer online regenerative breathing apparatus with wired remote control microwave heating device and application method of breathing apparatus

Abstract

The invention relates to a main transformer online regenerative breathing apparatus with a wired remote control microwave heating device. The main transformer online regenerative breathing apparatus comprises a main transformer body and an oil conservator connected with the former; the upper portion of the oil conservator is connected with a main transformer breathing tube; the main transformer breathing tube is connected with a three-way tube, and the other two ends of the three-way tube are connected to a first moisture absorption tank and a second moisture absorption tank via a first electromagnetic valve and a second electromagnetic valve, respectively; the first electromagnetic valve and the second electromagnetic valve are connected to the microwave heating device; the first electromagnetic valve, the second electromagnetic valve and the microwave heating device are all electrically connected with a wired remote control system by use of control cables. According to the main transformer online regenerative breathing apparatus with the wired remote control microwave heating device, only remote control operations are just performed on the main transformer online regenerative breathing apparatus far away from a transformer station main control chamber or a relay protection chamber around which high-voltage equipment main transformers are fully arranged or in other remote places, and energy loss is avoided; as a result, the main transformer online regenerative breathing apparatus has enormous advantages of high heating efficiency, use safety and the like.

Description

technical field [0001] The invention relates to the field of main transformer on-line regenerative respirator, in particular to a main transformer on-line regenerative respirator with a wired remote control microwave heating device and a use 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 carry a qualified and dry hygroscopic agent or a hygroscopic tank filled with a qualified hygroscopic agent to the main transformer surrounded by high-voltage electricity.

Problems solved by technology

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 carry a qualified and dry hygroscopic agent or a hygroscopic tank filled with a qualified hygroscopic agent to the main transformer surrounded by high-voltage electricity. Replace the hygroscopic agent on site. During the replacement process, the breathing tube of the main transformer is directly connected to the outside atmosphere, which will cause the breathing air flow of the main transformer to change, which may lead to serious failures of the main transformer’s gas relay heavy tile malfunction. Therefore, the traditional main transformer breathing device When replacing the adsorbent, the main transformer heavy tile protection device must be withdrawn before proceeding, and the withdrawal time is as long as 3-4 hours

[0003] Heavy tile protection is one of the most important protection devices for main transformer operation. Action to trip the main transformer switch to prevent further expansion of the accident. If the heavy tile is pulled out at this time, the main transformer switch will not be cut off, resulting in the expansion of the accident and even serious consequences of the main transformer explosion.

The protection device for removing heavy tiles needs to be approved by the chief engineer of the unit, and the operating personnel make a special trip to the main control room of the substation to operate, which is labor-intensive, time-consuming and expensive

[0004] The disadvantage of the traditional main transformer breathing device is that when the color-changing silica gel is replaced, after the moisture absorption tank is removed, the breathing airflow of the main transformer directly communicates with the outside atmosphere, making moisture and moisture easy to Intrusion into the main transformer oil through the breathing tube of the main transformer, and the replacement of the hygroscopic agent will cause waste and easily pollute the environment
