Description

A kind of local discharge signal harvester
Technical field
A kind of local discharge signal harvester of the utility model, relates to cable high-voltage partial discharge signal monitoring technical field; In particular to portion of cable splice place local discharge signal online acquisition technical field.
Background technology
Along with the develop rapidly of electric power networks and electricity consumption cause, new requirement be it is also proposed to the safe operation of electric power networks and electricity consumption; Specific to cable, its safe operation and security maintenance also inevitably more and more pay attention to by electric system.Cable is in operational process, if local has little defect or fault to produce local discharge signal, this shelf depreciation can aggravate the aging of cable insulation, the insulation of cable can be made to decline, can be breakdown time serious, finally cause cable major accident to occur, thus cause large-area power-cuts, the short time is caused to recover, the heavy economic losses causing personal safety and cannot retrieve.For stopping the generation of above-mentioned situation, all adopting cable high-voltage partial discharge signal monitoring method at present, its objective is by detecting shelf depreciation information, early detection is insulated potential fault or defect, thus reduces as much as possible or accident of stopping occurs.The method gathering local discharge signal from cable grounding line or cross interconnected case can be divided into portable and online two kinds.Conventional portable method, when monitoring local discharge signal, needs to carry portable instrument for measuring partial discharge, interim with the local discharge signal on high frequency CT sensor test ground wire or cross interconnected case grounding copper bar.If need to need tester repeatedly to descend tunnel to go test when frequently testing certain circuit, the test duration is shorter, and both inconvenience was also dangerous.And adopt the also unmanned realization of the method for the local discharge signal of on-line real time monitoring cable at present.The scene, cable tunnel that a kind of local discharge signal harvester can be installed for a long time is mentioned in this patent, the time of testing during with regard to solving above portable test operation is short, inconvenient and unsafe problem, achieves the function of the local discharge signal of on-line real time monitoring high-tension cable simultaneously.The utility model conscientiously and is fully being investigated, understands, analyzes, summing up on prior art and present situation basis, for overcoming and solving the deficiency, defect and the drawback that exist in prior art and real current situation and succeed in developing.
Utility model content
The purpose of this utility model is not meeting for prior art, to take " a kind of local discharge signal harvester " gordian technique, provides the new construction to Monitoring High Voltage Cable local discharge signal and new paragon.
For achieving the above object, the technical scheme that the utility model provides is: a kind of local discharge signal harvester, it is characterized in that: to open primarily of sky, lightning arrester, isolating transformer, modular power source, local discharge signal collecting unit, synchronous signal acquisition device, vasculum, HFCT sensor, Luo-coil, local discharge signal communication unit, server is formed.Described sky is opened, lightning arrester, isolating transformer, modular power source, local discharge signal collecting unit, synchronous signal acquisition device be mounted in vasculum inside; Described HFCT sensor have received local discharge signal, is transferred on local discharge signal collecting unit; Described Luo-coil receives a current synchronous signal, is transferred in synchronous signal acquisition device, then is transferred to local discharge signal collecting unit; Local discharge signal collecting unit incorporates local discharge signal and current synchronous signal, then signal transmission is to shelf depreciation communication unit, and the software being transferred to server after the conversion of shelf depreciation communication unit again carries out terminal processes.
Described a kind of local discharge signal harvester, is characterized in that: described local discharge signal collecting unit is the Data Acquisition Design based on FPGA.
Described a kind of local discharge signal harvester, is characterized in that: described local discharge signal communication unit is the Data Acquisition Design based on FPGA.
Described a kind of local discharge signal harvester, is characterized in that: be adopt multimode optical fiber to carry out communication between described local discharge signal collecting unit and the local discharge signal communication unit of outside.
Described a kind of local discharge signal harvester, is characterized in that: be adopt the mode of USB to carry out communication between described local discharge signal communication unit and server software.
Described a kind of local discharge signal harvester, is characterized in that: described signals collecting case is the metal cabinet that design becomes waterproof sealing.
When the utility model fully takes into account the monitoring of cable splice place local discharge signal, portable instrument for measuring partial discharge test duration short, inconvenient and unsafe feature; In order to better realize the actual state of high-tension cable partial discharge monitoring, implement the gordian technique of " a kind of local discharge signal harvester ", achieve the function of high-tension cable local discharge signal real time on-line monitoring, stop the generation of hidden trouble of cable safety, effectively solve exist in prior art and present situation deficiency, its design science rationally, simple and ingenious structure, effect stability reliably, be beneficial to and apply.
