Description
Technical field
The utility model belongs to electric circuit inspection technical field, particularly a kind of distribution line failure on-Line Monitor Device.
Background technology
Distribution, as a ring important in intelligent grid " six links ", is directly be connected with user and distribute the link of electric energy to user, in intelligent grid construction, has very important effect.Distribution system is made up of distribution substation (normally the transmission voltage of electrical network being reduced to distribution voltage), high-tension distributing line (i.e. more than 1 kilovolt voltage), substation transformer, low-voltage distributing line (less than 1 kilovolt voltage) and corresponding Control protection equipment.Because distribution line situation is complicated, once occur that line fault not only wastes a large amount of human and material resources, also can affect the production in city, household electricity, non-physical loss is huge.Staff searches and fixes a breakdown and can spend the more time, particularly after generation power-off fault, the time of artificial looking up the fault point is far longer than fault handling time, if staff can reduce the time spent by looking up the fault place, arrive in abort situation as early as possible, fix a breakdown and restore electricity, just can reduce a large amount of economic losses.
At present, in the distribution line failure on-Line Monitor Device on market, the way to take power of core unit failure indicator mainly contains two kinds: one is lithium battery+sun power power taking, and another kind is the transformer induced power taking of lithium battery+wire.Although what fault detector adopted is low power dissipation design, quiescent dissipation is less than 40uA, and life span requires to be not less than 10 years, and period is without other power supply.Such as lithium battery+sun power way to take power: under sunshine sufficient condition, solar panel can give lithium cell charging, but sun power electroplax life-span general about 5-8, and luminous energy is converted to electric energy efficiency and reduces year by year, almost be difficult to provide the electric energy meeting battery request to sun power electroplax end of lifetime, it is crucial that solar day is uncontrollable according to this condition, there is weather reason, also extraneous shelter reason is had, long-term so use can life-span of serious curtailment lithium battery, and final causing trouble indicator cannot normally work because of own power source problem.And the transformer induced way to take power shortcoming of lithium battery+wire mainly wire must have electricity, electricity-getting mutual inductor could obtain electric energy to lithium cell charging, and current in wire must be greater than certain value, general 15A, this way to take power in a short time should be out of question, but long-time circuit exists due to the transmission of electricity of load-reason small area analysis, or other reason cause circuit without electricity may, thus affect fault detector and normally works with lithium battery because overdischarge shortens the life-span.
Summary of the invention
The purpose of this utility model is to solve the problem, and provides a kind of and lithium battery, sun power power taking and the transformer induced power taking of wire is combined, extend the distribution line failure on-Line Monitor Device in fault detector serviceable life.
For this reason, the technical solution of the utility model is: a kind of distribution line failure on-Line Monitor Device, is characterized in that: it comprises power control unit, the first power management chip, second source managing chip, lithium battery, solar panel, electricity-getting mutual inductor, single-chip microcomputer, load current sensor and fault collection sensor; Described solar panel connects the first power management chip, the unidirectional connection power control unit of the first power management chip and lithium battery; Described electricity-getting mutual inductor connects second source managing chip, the unidirectional connection power control unit of second source managing chip and lithium battery; Described power control unit is bi-directionally connected single-chip microcomputer and lithium battery; Described single-chip microcomputer unidirectional connection first power management chip and second source managing chip; Described load current sensor and the unidirectional connection single-chip microcomputer of fault collection sensor; On described single-chip microcomputer, also control has malfunction indicator lamp and turns cup apparatus, and single-chip microcomputer also connects monitoring terminal by wireless module.
Before utility model works, the electricity obtained by solar panel delivers to power control unit after regulating via the first power management chip, and gives lithium cell charging simultaneously; The electricity obtained by electricity-getting mutual inductor delivers to power control unit after then regulating via second source managing chip equally, and gives lithium cell charging simultaneously; Through the comparison of power control unit, the information of each power supply is transferred to single-chip microcomputer, after single-chip microcomputer is analyzed, single-chip microcomputer controls the switch of the first power management chip and second source managing chip respectively, to select a road to export from the power supply of sun power and the power supply of electricity-getting mutual inductor; Rechargeable lithium battary be above-mentioned both cannot normally work time, power, as subsequent use to single-chip microcomputer and other peripheral hardware.During work, single-chip microcomputer obtains characteristic information by load current sensor and fault collection sensor, through the analysis of single-chip microcomputer to characteristic information, identify the fault that circuit occurs, by wireless module teletransmission to monitoring terminal, simultaneously Single-chip Controlling malfunction indicator lamp and turn cup apparatus work, indication fault information on the spot.
The utility model is by adopting the mode of lithium battery+sun power power taking+transformer induced power taking, and complement each other respective shortcoming to greatest extent; Power management chip can ensure that lithium battery can provide reliable source of power guarantee in stage fault detector life-cycle to greatest extent, thus make fault detector can mate more powerful less radio-frequency, strengthen communication distance, networking function also can realize, reduce data terminal and quantity is installed, saving national grid is invested, and also can realize strengthening communication frequency, is that main website is close to real-time acquisition line information.
