Description
Technical field
The utility model belongs to electric power network field, particularly relates to a kind of cable sheath grounding circulation detection system.
Background technology
At present, in the various design specifications of China, regulation, to exchanging, the elaboration that single core cable sheath grounding circulation detects is fairly simple, to the investigation of cities in China power-supply service department, cable line is every year all in the increase of larger proportion.Due to the existence of electromagnetic coupled, when cable length is different, its skin answers the mode such as financial single-point grounding, full ground connection (two-terminal-grounding), cross connection grounding, avoid due to the improper generation circulation of outer protective sleeve ground connection, cable grounding circulation is excessive, can affect the normal operation of each electrical device, heat gathers and can burn cable jacket for a long time simultaneously, causes immeasurable loss or disaster.For ensureing the normal operation of cable line, its overcoat ground current of Real-Time Monitoring and cable skin temperature are one of safe behaves.
Utility model content
Technical problem to be solved in the utility model is to provide replacement human at periodic intervals to patrol the cable sheath grounding circulation detection system that survey mode realizes Aulomatizeted Detect
The utility model adopts following technical scheme: a kind of cable sheath grounding circulation detection system, comprise and multiple acquisition terminal is set, at the cable splice two ends of the three-phase single cable of electric power tunnel difference set temperature sensor and current sensor, the temperature sensor of the cable splice of three-phase single cable co-located and current sensor are with an access acquisition terminal, multiple acquisition terminal connects into a telecommunication cable jointly, connect a main frame by described telecommunication cable, described main frame is connected to remote monitoring platform by communication.
Further, described main frame comprises signal acquisition module, single-chip microcomputer, data memory module and communication module, signal acquisition module, data memory module and communication module are connected with single-chip microcomputer, being connected to telecommunication cable by signal acquisition module sends data in single-chip microcomputer, single-chip microcomputer by all data according to the numbering of acquisition terminal stored in data memory module, big current data are transferred to monitor supervision platform by communication module by single-chip microcomputer in time.
Further, the output terminal of described single-chip microcomputer is connected with alarm, and the big current data detected are passed through alarm equipment alarm by single-chip microcomputer.
Compared with prior art, beneficial effect is the utility model:
The utility model detects the operation conditions of electric power tunnel inner high voltage cable and the current parameters of each high-tension cable metallic shield grounding point in real time by sheath grounding current sensor, temperature sensor and acquisition terminal, can realize accurately measuring 0 ~ 100A ground current and the measurement of temperature of cable junction, the regular ground current replacing Traditional Man mode patrols survey.Possess ground current transient state simultaneously and raise automatic trigger alarm function, when cable puncture, the situation such as short circuit time, circulating current increases instantaneously, and when more than more than 500A, main frame can will transfinite semaphore lock, by signal reporting monitor supervision platform.And can detection streamer copper shield, grounding box and go between stolen, for breakdown repair and localization of fault provide reference data.
Have and build effect that is real-time, accurate, accurate parameter reflection, managerial personnel and staff can be made to know the safety case of circuit in time.
