Problems solved by technology

[0005] 2. Disadvantages in the use of the SF6 decomposition product detection device at the present stage
After the data exceeds the range, the decomposition values ​​cannot be displayed correctly, and only one report of data exceeding the limit can be given when reporting the data.
It cannot provide good data support for analyzing the internal fault types of equipment
[0008] 2. Large-scale sensor collection type SF6 decomposition product detection device. The equipment pipeline is long and the internal sensor has high precision. It is easy to be polluted by a large amount of decomposition products generated by SF6 equipment failure, and it is difficult to restore the detection in a short time. Only by replacing the SF6 decomposition detection device can the detection be restarted
[0009] 3. It is inconvenient to use on-site for SF6 equipment failure emergency repair
At present, the large-scale sensor collection type SF6 decomposition product detection device is large in size, heavy, inflexi...

Abstract

The invention discloses a gas landmark decomposition product quickly detecting device and method of SF6 equipment after failure. The gas landmark decomposition product quickly detecting device of theSF6 equipment after failure includes a connector combination, a detecting host, and a filtering and adsorption device; the connector combination includes multi-type connectors connected to the SF6 equipment, and each multi-type connector is connected to a quick plug connector female; in the detecting host, an air inlet quick plug connector male is connected to the quick plug connector female, a H2S sensor and a SO2 sensor are used for detecting H2S gas and SO2 gas separately, and a single chip processes the measurement data of the H2S sensor and the SO2 sensor and displays the measurement result on a display screen; and the filtering and adsorption device processes the exhaust gas. The gas landmark decomposition product quickly detecting device and method of the SF6 equipment after failureimproves the quick response capability of the detection and positioning work in a SF6 equipment fault field, and improves the safety of the detection work in the SF6 equipment fault field.

Description

technical field [0001] The invention belongs to the technical field of electric power safety production, and in particular relates to a detection instrument that can be used for rapid fault location and fault type analysis in SF6 equipment repair operations. Background technique [0002] In recent years, with the gradual expansion of the scale of substations and the gradual increase in the number of SF6 substation equipment, SF6 equipment failures have also increased. At the same time, the requirements for power supply reliability are getting higher and higher, and the urgency of emergency repair work is also getting higher and higher. SF6 gas insulated combined electrical appliances, referred to as GIS equipment, has been adopted on a large scale in recent years. At this stage, the large-scale sensor collection type SF6 decomposition product detection device can adapt to the daily SF6 equipment status detection work (applicable to the normal operation of the equipment or t...
