Description

M271310 IV. Creation Description (1) [Technical Field to which the New Type belongs] This creation relates to a diaphragm valve breathing device, especially a diaphragm type that uses a hygroscopic container of oil-immersed motor equipment to replace a conventional isolation oil with a diaphragm valve. The respirator not only simplifies maintenance but also prolongs the useful life of the hygroscopic agent. [Previous technology] It is known that the volume of insulating oil of conventional oil-immersed motor equipment will expand and contract as the oil temperature rises and rises (at a normal temperature, the thermal expansion rate is about 7 * 10-4 ~ 8 * 10-4: thus causing breathing phenomenon In other words, when the oil temperature rises, the volume of the oil will force the internal gas of the electrical equipment to be discharged to the atmosphere. Conversely, when the oil temperature is lowered, air containing moisture and dust will be sucked in. The results of the breathing phenomenon throughout the year will affect the insulation oil. Various qualities (for example; insulation breakdown voltage, insulation power factor, moisture content, total price, interfacial tension, etc.) will even affect the reliability of motor equipment, which will worsen aging and shorten its use. Respirable images that can be avoided must be taken with appropriate respiratory protection measures to ensure the reliability of motor equipment and extend its service life. At present, motor equipment can be divided into three types of suction protection methods: one: open type, motor equipment has only moisture absorption The respirator allows breathing air to flow through the respirator to absorb moisture. Second, the diaphragm type, the motor equipment has a diaphragm to prevent the oil from contacting the air, but in order to reduce the water penetrated by the diaphragm It still has a hygroscopic respirator. Third: Nitrogen seal type, the electrical equipment is filled with nitrogen and its expansion and contraction is accommodated by another elastic expansion and contraction body that does not suck in air containing moisture. The extremely acidic and quick-acting touch equipment industry M271310 IV. Creation instructions (2) Most of the world adopts the former two methods, that is, the conventional oil-cup respirator is used to remove the moisture contained in the air that is inhaled. The structure of the conventional oil cup type respirator is shown in the schematic diagram of the first figure, that is, it has a hygroscopic agent container and an isolation oil cup, which are connected to a motor device through a pipeline. The isolation oil cup device is arranged at the lower end of the hygroscopic agent container. The oil cup is filled with about half a cup of insulating oil and the lower end of a breathing tube connected to a hygroscopic container is immersed in its oil. Its actions can be divided into three situations: One: B is no breathing situation, when the internal pressure of the motor equipment There is no breathing phenomenon when it is balanced with the external atmospheric pressure. The oil level in the breathing tube is equal to the oil level in the oil cup, so that the hygroscopic agent can be isolated from the atmosphere, and there is no need to absorb moisture to the high lift pressure part. When the shape of the breath exhalation oil is too breathable, the exhalation is empty. The tube suction is used to pressure the exhalation part, and the internal reserve is set to the machine drop potential and low oil drop. The second exhalation of the oil is forced by the cup of the low-reducing oil, and the oil makes the shape I, and the air intake f Γ: The third oil of the cup is sucked to the foot and the low-reduction pressure is provided. This machine is equipped in the suction part of the gas pressure part. The air in the gas-separated air is sucked into the air and can be sucked. The oil absorption on the upper surface will end when the agent comes out of the wet mouth. What are the original ten actions and the fact that the builders are absorbing their exhalation-type hair cups and testing the oil according to the knowledge and practice? Is it a matter of changing the questions and asking questions? The oil in the oil container of the time-capacity oil cup is intentionally injected by the oil. Often, it is necessary to reduce the amount of hair needed: steam, good change gradually disappears, and the dry cup will dry up.

Page 7 M271310 4. Creation instructions (3) Whether the position is normal, and the oil cup needs to be removed when refueling, which increases the burden of maintenance work. Second, the transparency of the oil cup will be contaminated by oil residue after a long period of use. At its oil level, the oil cup needs to be removed to remove oil residue, which increases the burden of maintenance operations. Third, the difference between the internal and external pressure of the breathing action varies according to the oil level of the oil cup. The lower the oil level, the easier the breathing action occurs. Because the oil cup is small, the internal and external pressure difference of the breathing action is even at normal oil level. It is also very small, in other words, frequent breathing movements will increase the consumption of hygroscopic agent and the burden of maintenance work on replacing the hygroscopic agent. In view of the importance of hygroscopic respirators in the protection of oil-immersed motor equipment, and in response to the needs of modern society, the electric industry has never stopped focusing on the quality and cost of power supply. The improvement of oil cup respirators is in the maintenance business. This is an urgent need. In order to achieve this urgent need, it is necessary to improve the lack of the conventional oil cup type respirator. [New content] This creation is mainly to solve the above-mentioned deficiencies, to avoid the existence of these deficiencies. This creation is to replace the conventional isolation oil cup respirator with a diaphragm valve breathing device, which not only simplifies maintenance operations but also prolongs the moisture absorption of oil-immersed motor equipment.
