Description
Technical field:
The present invention relates to a kind of insulated on-line monitoring system, be used for the on-line monitoring of transformer station's capacitance type equipment.
Background technology:
The existing insulated on-line monitoring system of installing of power system transformer substation.The sensor that uses is divided into active and passive two kinds of forms.The active sensor poor anti jamming capability, measured data instability, and sensor construction complexity.Passive sensor directly is connected on the equipment end, though do not change the method for operation of equipment, more emat sensor and inconvenience.The insulated on-line monitoring system of Changchun Power Supply Company, Jilin Electric Power Co., Ltd.'s independent research is regenerated by continuous remodeling through for many years continuous exploration, is widely used in production reality.We adopt the passive punching sensor of single turn, and sensor safe, convenient and swift is changed in its method of operation stable and reliable operation that does not change equipment simple in structure.
Transformer station's capacitance type equipment is not if carry out on-line monitoring, and whether the test that need have a power failure in 2 to 3 annual periods satisfies service requirement to check its insulating property.Article one, 220kV power circuit power failure test needs about 2 hours, adds and stops sending the electricity running time, and every 220kV power circuit has a power failure to test and needs about 4 hours.The test that has a power failure causes the waste on human and material resources, the financial resources.Insulated on-line monitoring system can be measured dielectric loss angle and electric capacity, measurement Zinc-Oxide Arrester total current and the current in resistance property of 220kV capacitance type equipment at any time, uses this device in the automatically test or to test 60 phases (3 is a circuit mutually generally speaking) at place remote only be about 12 minutes of transformer station's master-control room.The measured data and the measured data basically identical that has a power failure.
Summary of the invention:
The object of the present invention is to provide a kind of insulated on-line monitoring system, guaranteed the safe operation of electrical network, can in time find equipment deficiencies such as 220kV main-transformer sleeve pipe, capacitance type potential transformer, coupling condenser, current transformer, lightning arrester, make the insulation status of 220kV capacitance type equipment be in anywhere or anytime controlled, control, can the control state; And, repair based on condition of component can rely on data for providing.
Technical scheme of the present invention is achieved in that insulated on-line monitoring system, can measure capacitance type equipment electric capacity and dielectric loss angle and Zinc-Oxide Arrester total current and current in resistance property, it is characterized in that: main frame is made of front end processor and main control computer two parts, device signal is sent into front end processor through sensor, cable, signalling channel adopts three core screened cables, the internal layer shielding is copper mesh, and outer shielding is the steel armour; Front end processor is handled input signal, gets the voltage transformer pt secondary voltage by selecting phase, phase shift, all measures, uniline is measured, the single-phase measurement of uniline; And measurement result directly sent into main frame; Front end processor is sent into measurement result, busbar voltage and temperature, the humidity of main frame and is carried out data processing, and measurement result shows that directly main frame has the software analysis expert system on scene and the distant place computing machine.
Good effect of the present invention is dielectric loss angle and the electric capacity that is used for measuring the 220kV of transformer station main-transformer sleeve pipe, capacitance type potential transformer, coupling condenser, current transformer, and the current in resistance property of Zinc-Oxide Arrester and total current; Can be in the automatically test or test 60 phase capacitance type equipments at place remote and only need about 12 minutes of transformer station's master-control room, and setting measurement parameter as required; Automatically measure and preserve measurement data of temperature every day the highest and temperature at 14 at minimum 4, form form and curve and store automatically, in case during superscalar data, device will send the acoustic signal of warning; Setting measurement time and cycle arbitrarily.
Description of drawings:
Fig. 1 is a principle of work block diagram of the present invention;
Embodiment:
The present invention will be further described below in conjunction with accompanying drawing: as shown in Figure 1: insulated on-line monitoring system, can measure capacitance type equipment electric capacity and dielectric loss angle and Zinc-Oxide Arrester total current and current in resistance property, it is characterized in that: main frame is made of front end processor and main control computer two parts, device signal is sent into front end processor through sensor, cable, signalling channel adopts three core screened cables, the internal layer shielding is copper mesh, and outer shielding is the steel armour; Front end processor is handled input signal, and power taking presses mutual inductor (PT) secondary voltage by selecting phase, phase shift, all measures, uniline is measured, the single-phase measurement of uniline; And measurement result directly sent into main frame; Front end processor is sent into measurement result, busbar voltage and temperature, the humidity of main frame and is carried out data processing, and measurement result shows that directly main frame has the software analysis expert system on scene and the distant place computing machine.
After the user opens computing machine during use, show " on-line monitoring " file on the desktop, enter TTC-2 on-line monitoring operating system, more whether system prompt new data, and whether more the user can be by oneself needing selection new data." control far away " has following function: single-path testing, all tests, data transmission, long-range connection." browse " following function is arranged: single channel data, total data, real-time curve, K line chart, anomaly analysis." statistics " has following function: selective printing, sampling are printed.After the long-range connection, select transformer station, the user can carry out single-path testing, whole test, data transmission as required.After entering single channel or single-phase test, after the selection device line title, select the phase sequence of A, B, C phase again, the data that can test this equipment.
All tests: test all device datas.By " all tests " key.After all testing, system tests automatically to all devices, preserves data after test finishes automatically.
The real-time curve display mode has: inferior line chart, Day Line Chart, 7,15, monthly line chart are to utilize test data to be depicted as curve, can carry out qualitative and quantitative analysis to some equipment records waveforms.Select a certain equipment, the A of this equipment, B, C phase related data curve and temperature, moisture curve show, can move forward and backward curve by " moving " key.Carry out data analysis and judgement.
Anomaly analysis: when insulated on-line monitoring system measurement data overshoot value, when a distant place entered the insulated on-line monitoring system interface, system is the some transformer stations of prompting automatically, and measurement data has problem, and the equipment of people finder's data exception is watched in prompting.
