Description
Technical field
The utility model relates to a kind of monitoring device, especially based on the GIS shelf depreciation intelligent online monitoring device of multiple spot monitoring and signal step-out time analysis.
Background technology
GIS is the air that adopts SF6 gas not adopt to be under the atmospheric pressure metal enclosed switchgear as insulating medium.Form by isolating switch, disconnector, grounding switch, mutual inductor, lightning arrester, bus, web member and outlet terminal etc.; These equipment or parts all are enclosed in the shell of metal ground connection, and portion is filled with the excellent SF6 gas of insulating property and arc extinction performance as insulation and arc-extinguishing medium within it.GIS equipment has extensively run on all over the world since the sixties in 20th century practicability.GIS not only is widely used in high pressure, UHV (ultra-high voltage) field, and also is used in the extra-high voltage field.Compare with conventional open type transformer station; The advantage of GIS is compact conformation, floor area is little, reliability is high, flexible configuration, easy for installation, high safety, adaptive capacity to environment are strong; Maintenance workload is very little; The maintenance intervals of its critical piece is not less than 20 years, is the visual plant of electric system, is the basis that guarantees power supply reliability.Though GIS seldom need safeguard,, will cause that local so that whole areas have a power failure in case break down because the inner field intensity of GIS is very high.And the main cause that causes equipment failure is the deterioration of its insulating property.The economic loss that the fault of large-scale GIS equipment causes is huge, if fault causes sudden blast also to cause personnel's injures and deaths easily.Up to the present, domestic the GIS substation accident that a lot of because GIS insulation fault causes taken place.What As GIS was used popularizes, and the insulation control means that improve GIS have been the task of top priority.
The generation of GIS insulation fault, mainly be production, on-the-spot install and process such as operation in, GIS air chamber inside stays defective and causes the generation of fault in service.Simultaneously when gas insulated combined electric appliance equipment uses; Regularly the shelf depreciation to its inside detects; To ensureing that its safe handling has important effect, the inside shelf depreciation of gas insulated combined electric appliance equipment is an important index, and gas insulated combined electric appliance equipment partial discharge monitoring technology is progressively used at present; To different electrical equipments and requirements of different users; The form of GIS local discharge on-line monitoring device is single, thereby makes the application mode of GIS local discharge on-line monitoring device single, can not satisfy requirements of different users.
Summary of the invention
The utility model is to be solved to be exactly that the application mode of GIS local discharge on-line monitoring device is more single; Can not effectively get rid of on-the-spot undesired signal; Can't put a little accurately location to GIS inside office; The problem that is difficult to meet consumers' demand provides a kind of GIS shelf depreciation intelligent online monitoring device based on multiple spot monitoring and signal step-out time analysis.
The GIS shelf depreciation intelligent online monitoring device of the utility model; It is characterized in that this monitoring device comprises UHF sensor, field monitoring unit and central control unit; The UHF sensor is installed on the GIS equipment; The field monitoring unit is connected with the UHF sensor through coaxial cable for high frequency, is connected with IP network between central control unit and the field monitoring unit.
Described UHF sensor is no more than eight, is divided into built-in sensors and outer sensor, and built-in sensors is installed in the monitoring window place of GIS equipment, and outer sensor is installed on the disc insulator of GIS equipment.
Described GIS shelf depreciation intelligent online monitoring device also is provided with the ground unrest sensor; The ground unrest sensor is arranged on around the UHF sensor; Be connected with the field monitoring unit; Also deduct through gathering the ground unrest undesired signal, thereby reduce the interference of on-the-spot diversity of settings noise, fixed frequency range telecommunication path signal and other burst unknown signalings the discharge signal processing of true office through software analysis.
The field monitoring unit through anti-interference process such as mixing amplification, high-speed sampling and the filtering of small echo threshold values, extracts effective internal office discharge signal through the triple filtering circuits of hardware; Handle the back through the PRPS/PRPD algorithm and be uploaded to central control unit through IP network; CPU gathers the signal of sending here from the field monitoring unit, sets up the fault mode database, and GIS partial discharges fault type is diagnosed drawn game discharge source location; Positional accuracy is high, be other method can't be obtained.
The GIS shelf depreciation intelligent online monitoring device of the utility model; Simple in structure, design science, easy to use; Because the discharge pulse duration that shelf depreciation produces has only several ns; And frequency spectrum is up to 1500MHz, and decay is exceedingly fast when in air, propagating simultaneously, and the ultra-high frequency signal that shelf depreciation produced that adopts the UHF sensor and receive GIS equipment can be realized the real time on-line monitoring to the GIS local discharge signal; Adopt a plurality of UHF sensor to receive the mistiming of the UHF signal of same office discharge source generation simultaneously; According to these signal time differences and electromagnetic wave propagation speed, accurately locate the discharge source position of just playing a game then, and setting accuracy is high.
