Description
Technical Field
The invention relates to the technical field of maintenance of electrical equipment, in particular to a device for changing and purifying SF6 gas.
Background
The insulating strength of SF6 gas is greatly higher than that of the traditional insulating gas and has good arc extinguishing performance, so that the SF6 gas is widely applied to electrical equipment such as circuit breakers, GIS and the like. With the large number of electrical devices put into use, ventilation and inflation operations of SF6 gas in the electrical devices are often required. After the electrical equipment is used for a certain period of time, the old SF6 gas in the equipment contains a certain amount of moisture, and the storage equipment of the SF6 gas may also contain a certain amount of moisture, so that the electrical equipment needs to be replaced or new SF6 gas needs to be supplemented.
The electrical equipment is replaced or new SF6 gas is supplemented at present, the electrical equipment is disassembled, parts are replaced and vacuumized after power failure, ventilation and inflation are carried out, the operation and maintenance cost is increased, the power supply reliability is reduced, the SF6 gas capacity in the electrical equipment is automatically tripped when the capacity of the SF6 gas is reduced to a certain degree, and once the SF6 gas is tripped, a large amount of manpower and material resources are consumed to recover the normal power supply of a power station, so that the influence on regional power systems is very large. Meanwhile, in the ventilation and inflation processes, the capacity of SF6 gas in the electrical equipment cannot be accurately measured in real time and can only be checked manually, so that the working efficiency is low, and therefore, the SF6 gas replacement device is urgently needed, the SF6 gas can be replaced or supplemented to the electrical equipment under the conditions of no power failure and no interruption, and meanwhile, the capacity of the SF6 gas in the electrical equipment can be monitored in real time.
Meanwhile, due to the reasons of pipeline materials, connection modes of the pipeline and an electrical equipment interface and the like, the conventional SF6 gas inflation equipment can leak in the process of supplementing SF6 gas to the electrical equipment, and particularly SF6 gas is easy to leak when the pressure difference between the inside of the equipment and the outside air is caused. If the leaked SF6 gas cannot be treated in time, the leaked SF6 gas is discharged into the atmosphere, so that a great potential safety hazard is caused, and the personal safety of operators and the operation safety of a power grid are seriously threatened.

The working process of the invention comprises the following steps: the staff covers the leakage-proof cover on the SF6 air supply port of the electrical equipment, the air supply port is aligned to the air supply port, the external SF6 air tank is in threaded connection with the air supply port, then the plugging cap is twisted off, and the switches of the air changing box and the purifying box are pressed down, so that the device starts to work. The gas density sensor, the gas pressure sensor and the micro water content sensor which are arranged on the gas pipe are used for collecting information such as the air pressure, the density and the humidity of SF6 gas in the electrical equipment, information data are transmitted to the singlechip, the singlechip compares the real-time value of the physical quantity with a previous protection value, and when the humidity value and the density value are judged to be lower than the protection value, the singlechip opens the lower port of the electric three-way ball valve, the exhaust one-way valve, the exhaust power valve, the exhaust ball valve and other equipment to perform ventilation work. When the SF6 gas pumped out flows through the air extraction pipeline and is detected by the gas pressure sensor in front of the first induced draft fan, the singlechip receives signals of the gas pressure sensor and then starts the front induced draft fan and the rear induced draft fan to suck the SF6 gas into the purifying box, when the SF6 gas passes through the air filter screen, the air filter screen filters large particle impurities in the gas, then the nozzles on two sides start to spray clean water to remove sulfide substances in the SF6 gas, the clean water is changed into part of sewage after absorbing the sulfide substances, the part of sewage falls into the wastewater tank after passing through the sponge and the first screen, the part of the sewage is absorbed by the sponge, and the gas after removing the sulfide substances passes through the activated carbon deodorizing filter screen and the HEPA filter screen in sequence and becomes pollution-free gas, and the pollution-free gas can be directly discharged into the atmosphere through the exhaust pipeline. In the water spraying process of the nozzle, after the gas sensor cannot detect that the gas flows through, the water spraying is stopped after the gas sensor delays for half a minute to 1 minute, then the singlechip starts two telescopic motors to control the pressing plates to squeeze the sponge, and the water absorbed before the sponge is discharged as much as possible through reciprocating extrusion, so that the device is prepared for the next use. After the sewage extruded from the sponge falls into the wastewater tank, the sewage is subjected to chemical reaction with barium hydroxide solution in the tank like the sewage flowing in before, sediment such as barium sulfate generated by the reaction is blocked by the second screen, the water is basically pollution-free, and finally, a worker unscrews a circular drain valve of a drain outlet at the bottom of the filter tank anticlockwise, so that the water is discharged outwards. In the purification process, a worker can start two telescopic motor control pressing plates to squeeze the sponge through the display screen according to actual conditions, so that excessive water is not accumulated in the exhaust channel.
When the air pipe interface is in butt joint with the SF6 air supplementing interface of the electrical equipment, or when the interface is separated from the interface after air filling, SF6 gas possibly leaks due to pressure difference between gas in the equipment and external gas, and the leaked SF6 gas is pumped into the purifying box for treatment after passing through the exhaust pipeline and the air extracting pipeline in the leakage-proof cover, and the process is the same as the above.
In the ventilation process, when the micro water content sensor detects that the micro water content value of SF6 gas in the electrical equipment is lower than another preset value, the ventilation is finished, and the singlechip closes the exhaust passage according to a preset program, namely closes the lower port of the three-way valve, and stops the operation of the equipment such as the exhaust power valve, the exhaust ball valve and the like. Then, the upper port of the three-way valve, the air inlet one-way valve, the air inlet power valve, the air inlet ball valve and other devices are opened, new SF6 gas is supplemented to the electrical device, and when the gas pressure sensor detects that the SF6 gas pressure value in the electrical device is the rated highest pressure value (0.6 Mpa), the singlechip closes the air charging pipeline to stop air charging. Through the reciprocating circulation for a plurality of times, SF6 gas of the electrical equipment is replaced, so that the purpose of timely replacing the SF6 gas is achieved. In the process, when the device normally operates, green LED lamps prompt normal operation, and if failure and other inoperable conditions occur, red LED lamps prompt staff. Meanwhile, the staff can see the data of the air exchange and the data of SF6 gas in the electrical equipment through the display screen, the IP address of the singlechip can be stored in the background system, at the moment, the staff can check the related data of the air exchange and the air exchange in real time through the public network and manually and remotely control the air exchange and the air exchange, for example, the gas amount in the SF6 gas tank can be estimated according to the weight of the newly-supplemented SF6 gas detected by the micro-weighing sensor so as to replace the gas tank in time, or if the device automatically supplements the air to the electrical equipment for a plurality of times in a short time, the time interval of the air supplement is checked, and if the air supplement time interval is gradually reduced, the staff can estimate the leakage condition of the SF6 gas in the electrical equipment.
The foregoing description of the preferred embodiments of the invention is not intended to be limiting, but rather is intended to cover all modifications, equivalents, alternatives, and improvements that fall within the spirit and scope of the invention.
