Description

Technical Field

[0001] The present application relates to the field of GIS disassembly and assembly operations, and specifically to an integrated device for detecting and processing the GIS installation and maintenance environment. Background Art

[0002] With the development of the electric power industry, the increase of transmission voltage level, and the formation of large-scale cross-regional networking, high requirements are placed on the reliability of power transmission and transformation equipment in the power system. Compared with traditional open high-voltage equipment, gas-insulated fully enclosed switchgear, referred to as GIS (GAS INSUIATED SWITCHGEAR), has obvious advantages: compact structure, greatly reduced space occupied by the entire device; not affected by the external environment, high operating reliability; long maintenance cycle. Since its advent in the 1960s, GIS has developed rapidly and occupies an important position in the power transmission and transformation system.

[0003] When installing GIS equipment, in order to ensure the quality of equipment installation and improve the reliability of equipment operation, there are relevant requirements for the environmental cleanliness, humidity, temperature and wind speed of the installation site: the environmental cleanliness reaches above one million level, the environmental humidity does not exceed 80%, the temperature is -10~40℃, and the wind speed is less than 5m / s. However, the current installation (maintenance) environment cannot meet the above requirements. During the installation of GIS equipment, the environmental cleanliness requirements are relatively high, and it is necessary to reach the ios9 level of ISO14644 standard. The specific standards are: the amount of floating dust with a particle size of not less than 0.5μm shall not exceed 35,200,000; the amount of floating dust with a particle size of not less than 1μm shall not exceed 8,230,000; the amount of floating dust with a particle size of not less than 5μm shall not exceed 293,000. In addition, there are some other environmental requirements: environmental floating dust is below 20CPM, the ambient temperature is between -10℃ and 40℃, the ambient humidity does not exceed 80%, and the ambient wind speed is below 5m. Since substation construction is distributed throughout the country, the environment in each place is different. It is difficult for the environment in some areas to meet the environmental requirements for GIS equipment installation. If a fresh air system is added to the substation construction, although it can effectively solve the environmental problems when GIS equipment is installed in the initial stage of construction, after the substation GIS equipment is installed, the substation fresh air system will be idle for a long time (only used for maintenance in the later stage), resulting in a waste of resources. At the same time, the fresh air system will often fail if it is not used for a long time, which greatly increases the construction cost and maintenance cost of the substation. Therefore, many substations no longer install fresh air systems during construction, resulting in a situation where the substation lacks environmental treatment equipment.

[0004] In the current GIS equipment installation and maintenance process, in the outdoor environment, due to unfavorable factors such as changeable weather and flying dust, the installation and maintenance of equipment has brought many challenges. In order to cope with these challenges, some areas have begun to use dust-proof sheds for outdoor construction and equipped with purification equipment to create a cleaner and more stable working environment.

[0005] A dustproof shed is a temporary protective structure designed for outdoor installation and maintenance of GIS equipment. The size and shape of a dustproof shed generally need to be determined based on the size of the equipment and the needs of maintenance work to ensure that it can fully cover the equipment and work area that need protection.

[0006] The construction of a dustproof shed can not only effectively prevent dust, sand and other impurities from entering the working area and reduce the risk of equipment contamination, but also provide a relatively stable working environment to prevent weather changes from having an adverse effect on maintenance work. Purification equipment is usually installed in the dustproof shed to further improve the cleanliness of the working environment. These purification equipment include air purifiers, dehumidifiers, etc., which can remove dust, particulate matter, etc. in the air, while ensuring that the environmental humidity meets the requirements.

[0007] During the installation and maintenance of GIS equipment, it has become a common practice to use a combination of dustproof sheds and purification equipment.

[0008] However, the prior art has the following disadvantages:

[0009] 1. GIS outdoor installation (maintenance) uses a dustproof shed, which is equipped with an air purifier, dehumidifier, etc. However, the processing equipment is all independent unit equipment, which is large in number and inconvenient to use and maintain.

[0010] 2. The existing GIS detection equipment has a single function. Different detection contents require different detection equipment, which is inconvenient to use.

[0011] 3. Existing testing equipment requires frequent manual testing and recording, which is time-consuming and labor-intensive, data is easily lost, and there is a phenomenon of falsification and tampering of recorded data.

[0012] 4. Currently, there is a lack of dedicated environmental treatment equipment for indoor GIS installation (maintenance). Usually, other projects in the substation are stopped and construction is carried out in suitable weather to reduce the impact of the environment on the installation quality. This method seriously affects the construction progress. In addition, in some areas and seasons, the installation environment is still difficult to meet the needs of GIS installation (maintenance). Summary of the invention

[0013] The purpose of the embodiment of the present application is to provide an integrated device for GIS installation and maintenance environment detection and processing, which integrates the environmental detection and environmental processing functions into one, so that it has dual functions of detection and processing, and will be more suitable for the actual needs of GIS installation and maintenance scenarios.

[0018] The exhaust assembly includes a main shell, an air inlet pipe, an air outlet pipe, a filter layer, an axial flow fan and a corrugated hose.

[0071] like Figures 7 to 9 As shown, the equipment operation process

[0072] First, move the GIS installation, maintenance, environmental detection and treatment integrated device into the substation room via the walking wheels 1, press the button switch 5 to turn on the device; the home page display area displays the current suspended dust value, oxygen content / SF6 leakage value, and ambient temperature / humidity value.

[0073] In the controller 3 parameter settings, set the standard values ​​of PM0.5, PM1.0, PM5.0, O2, SF6, and humidity respectively.

[0074] The dust particle detection sensor, temperature detection sensor, humidity detection sensor, O2 and SF6 detection sensors in the sensor component installation box 6 respectively feed back the indoor environment detection results to the data preprocessing unit, and the data preprocessing unit converts the detected electrical signals into unified digital signals, which are input into the data processing unit, and then the data is displayed through the display interface. When the data fed back by the sensor does not reach the preset standard data, the red light in the alarm function area of ​​the display interface lights up, and the alarm light 4 flashes red.

[0075] In the Start / Stop Settings column of the display interface, click on the device with a red light on to enable the relevant environmental management function items:

[0076] When the humidity does not reach the standard value, click the dehumidification start function button, the equipment dehumidification component 9 works to perform dehumidification processing, and the air flow input and output are as follows Figure 7 shown.

[0077] When the dust particles in the air do not reach the standard cleanliness level, click the purification start function button, and the equipment purification filter component 11 and the centrifugal fan 12 will start to perform purification.

[0078] When the humidity and dust particles in the air / environmental cleanliness do not reach the standard value, the dehumidification and purification function buttons can be turned on at the same time, and the equipment will perform dehumidification and purification at the same time.

[0079] After the dehumidification and purification of the equipment reaches the set standard value, the equipment automatically shuts down, and the alarm light 4 and the display lights in the alarm function area of ​​the display interface all turn green.

[0080] When SF6 gas leakage occurs in the room during the inspection process or beforehand, the SF6 and O2 sensors will detect the SF6 in the air and the oxygen content in the air, and the alarm light 4 will sound an alarm.

[0081] First open the rear cabinet door 7. Figure 4 As shown, the corrugated hose 1006 is installed in the air inlet pipe 1002 and the air outlet pipe 1003 ports in the extraction component 10, and then the extraction end of the corrugated hose is placed at the SF6 leakage point, and the exhaust end of the corrugated hose is placed outdoors. Click the extraction function button in the controller 3 to start the extraction function. When the SF6 content is extracted to within the set standard, the equipment automatically shuts down, and the alarm light 4 and the alarm function area of ​​the display interface show green lights.
