Description
Technical field
The utility model belongs to SF6 cabinet discharging detection device technical field, is specifically related to a kind of SF6 gas-insulated ring network cabinet with local discharge on-line monitoring device.
Background technology
At present, 10kV metal-enclosed switchgear is used widely in transformer station and large-scale user, and its security of operation directly affects the reliability that whole transformer station powers.Therefore, be the key ensureing switch cubicle safe operation to the monitoring of switch cubicle running status and anticipation and rationally maintenance.Within accident incubation period, have electric discharge phenomena before switch cubicle breaks down produce, therefore by the relevant information of the hidden danger that can obtain the detection of electric discharge insulating; The electric discharge of 10kV inside switch cabinet mainly contains surface discharge, internal discharge, corona discharge etc.; In discharge process, energy mainly discharges with electromagnetism, sound wave and gas form.These become local discharge signal and contain abundant state of insulation information, can effectively reflect the defect produced in the manufacture of 10kV metal-enclosed switchgear, installation and running, generation and the order of severity thereof of insulation fault can be detected, thus propose to report to the police at the commitment of accident, in a planned way to arrange maintenance, the damage of minimizing equipment, avoids accident that the massive losses brought occurs.Therefore, the detection of partial discharge, evaluation and location become one of most important means of 10kV metal-enclosed switchgear condition monitoring; A kind of on-line monitoring positioner of local discharge of gas-insulator switchgear is disclosed in Chinese patent CN 201697998 U, comprise, amplify and the signal conditioning circuit of filtering for signal, it is characterized in that: also have, transducer: be made up of the antenna at each boxlike insulator place being placed in SF6 gas insulated transformer substation; Intelligent selection switch: be connected with each antenna of transducer, with gating antenna in turn, and is connected with described signal conditioning circuit by radioshielding coaxial cable; High-speed machine tools: its data acquisition channel is connected with the output of signal conditioning circuit; Processor: be connected with high-speed machine tools by bus, and be connected with intelligent selection switch by bus; But its complex structure, operation inconvenience, the device of the gas-monitoring dielectric transmission line partial discharge therefore needing a kind of structure simple and easy and simple to handle.
Utility model content
Technical problem to be solved in the utility model is for locating not accurate and baroque problem in prior art, and a kind of SF6 gas-insulated ring network cabinet with local discharge on-line monitoring device provided.
The technical scheme adopted for solving problem of the present utility model is: a kind of SF6 gas-insulated ring network cabinet with local discharge on-line monitoring device, comprise cabinet, uhf sensor, vibrating sensor, sound transducer, signal analysis unit, signal transmission unit, partial discharge monitoring terminal, described uhf sensor, vibrating sensor and sound transducer to be arranged in cabinet and to be connected with signal analysis unit signal respectively, described signal analysis unit and signal transmission unit signal interconnected, described signal transmission unit is connected with partial discharge monitoring terminal signaling.
Described signal transmission unit is 4G Signal transmissions.
Described partial discharge monitoring terminal is microcomputer, and described microcomputer connects alarm.
In described partial discharge monitoring terminal, GIS model is set.
The utility model arranges uhf sensor, vibrating sensor and sound transducer in cabinet, the uhf electromagnetic wave signal produced when making it can gather partial discharge, thus obtains the information of electric discharge; Due to before partial discharge, electric field stress around point of discharge, pressure stress and particle power are in relative balance state, electric charge then can be made when a partial discharge occurs fast to discharge or migration, make point of discharge surrounding electric field stress, pressure stress and particle power out-of-balance condition and produce vibration, therefore vibrating sensor is set in cabinet and sound transducer makes both combinations can orient the position of point of discharge accurately; And due to vibration and the communication process of sound wave lossy, therefore the utility model arranges transducer and makes to detect more accurate in cabinet; Adopt three transducers, two kinds of metering systems, make two kinds of modes combine the precision that ensure that measurement; And adopt 4G Signal transmissions guarantee information can realize radio communication, what partial discharge monitoring terminal adopted simultaneously is microcomputer, it being arranged GIS model makes it can accurately navigate to concrete cabinet by transducer, and the particular location be accurate in cabinet, make maintainer before going maintenance, directly can be positioned to point of discharge.
The mode that the utility model is combined by three kinds of transducers, two kinds of metering systems, make it possible to the information such as type, position, size of current detecting point of discharge, and can organize into groups cabinet, it can be managed in systematization, connect alarm can to analyze fast when there is electric leakage, because it is easy and simple to handle, be therefore worthy to be popularized and application.
