Novel ring main unit SF6 gas leakage on-line monitoring device

Abstract

The invention relates to a novel ring main unit SF6 gas leakage on-line monitoring device. The on-line monitoring device comprises a monitoring device, a wireless transmitter, a plurality of SF6 gas collectors, a pressure sensor, an audible and visual alarm, a blower and a cloud remote server. By arranging the SF6 gas collectors, precision on SF6 gas collection is improved; by arranging the pressure sensor, when the gas pressure inside the ring main unit changes, safety treatment can be carried out on the ring main unit as well; by arranging a blower controller, when the concentration of SF6 gas is too high, the blower controller can be used for driving the blower to work, so as to reduce the concentration of SF6 gas inside the ring main unit; by arranging a display unit, real-time observation and learning on the concentration of SF6 gas can be facilitated; by arranging a GSM/GPRS module, the network transmission of signal data can be realized, and the working efficiency is improved.

Description

technical field [0001] The invention relates to an on-line monitoring device for SF6 gas leakage used in the electric power industry, in particular to a novel on-line monitoring device for SF6 gas leakage of a ring network cabinet. Background technique [0002] After retrieving the relevant patent documents, a new type of on-line detection device for SF6 gas leakage of the ring main unit used in the ring main unit of the electric power industry with the same structure as the present invention has not yet been found. At present, the leakage of SF6 gas in the ring network cabinet of the power industry occurs from time to time. When SF6 gas contacts with the moisture in the air, some highly toxic substances will be produced, which poses a threat to the lives of the staff. Therefore, there have been some monitoring methods for SF6 gas leakage. The device is used to remind the staff to take preventive measures in time. Although the existing monitoring device has achieved intellig...

Problems solved by technology

At present, the leakage of SF6 gas in the ring network cabinet of the power industry occurs from time to time. When SF6 gas contacts with the moisture in the air, some highly toxic substances will be produced, which poses a threat to the lives of the staff. Therefore, there have been some monitoring methods for SF6 gas leakage. The device is used to remind the staff to take preventive measures in time. Although the existing monitoring device has achieved intelligent monitoring and processing, the form of SF6 gas detection in the cabinet is relatively simple and the detection is not comprehensive. At the same time, the detection results are sometimes inaccurate. The staff knew about it at the first time, and the problem could not be solved quickly. Secondly, the internal central processor of the entire SF6 gas leakage monitoring device needs to be manually upgraded regularly, and there is a lack of an online intelligent upgrade and archiving system.
