Description
Technical field
The utility model relates to a kind of separate type outdoor high-voltage switch.
Background technology
Build medium-term and long-term development plan according to national grid; the optical, mechanical and electronic integration equipment of the intelligent development level of outdoor high-voltage switch can be monitored, diagnose and protect, promote to exploitation for a long time automatically to the high-voltage electric power system running status, be the march toward an urgent demands of automation of urban and rural power grids.
From 2006, domestic power network automation particularly outdoor high-voltage switch automation began to be rapidly developed.The realization of grid automation requires outdoor high-voltage switch to be equipped with intelligent controller.The various intelligent controller demands that the outdoor high-voltage switch that various functions are different is joined are being multiplied every year.These controllers comprise reclosing controller, prepared auto restart duplicate supply controller, permanent magnet mechanism controller, user demarcation load switch controller, user demarcation breaker controller and other tracer (FDR) or the like, and there is the intelligent controller manufacturer of the number man specialty that comprises that I take charge of in the whole nation.Above-mentioned controller all adopts conventional voltage transformer to do power supply and voltage detecting source.Conventional voltage transformer is transformed to 100VAC commonly used or 220VAC with high pressure such as 10KV etc., so that intelligent control part and switch divide-shut brake power supply to be provided by electromagnetic induction.The shortcoming that all voltage transformers have not only that volume is big, Heavy Weight, consumption of natural resource are many, cost an arm and a leg, also influenced when being installed in the city appearance of the city, and voltage transformer is installed more for a long time, because resonance easily takes place in its inductive nature and the existence of line mutual-ground capacitor on the line, at this moment, voltage transformer will be impaired, also can blast when serious.In addition, because line voltage distribution is when too high, voltage transformer also damages easily, so there are many defectives in voltage transformer.But up to ending today, outdoor high-voltage switch manufacturer of national hundreds of family is always at the working voltage instrument transformer.Carry out overcurrent protection during outdoor high-voltage switch work and be absolutely necessary, this just at first must be equipped with current transformer; Along with the raising day by day of power distribution automation degree, outdoor high-voltage switch begins to realize intelligent more and more, i.e. the control of intelligent terminal of every outdoor high-voltage switch palpus outfit user required function.And must having power supply to provide, control of intelligent terminal could work, so also will be equipped with working power and the line voltage distribution detection resources of voltage transformer so that controller to be provided.Therefore, if three-phase current and three-phase voltage are detected, then every switch at first must be equipped with three current transformers and two voltage transformers.Current transformer by 300 yuan/only calculate, voltage transformer is by 3500 yuan of calculating, then the expense of every switch institute distribution current transformer and voltage transformer just reaches nearly 8000 yuan, the height of visible cost; On the other hand, above-mentioned instrument transformer main raw material(s) is high-quality silicon steel sheet and copper paint envelope curve and epoxy resin, and the weight of three current transformers and two voltage transformers adds is in the same place, 50 kilograms at least, and heavy then kilogram up to a hundred.By annual 450000 outputs that electric pressure is the 6-40KV switch in the whole nation,, then need consume at least 22500 tons of high-quality silicon steel sheet and copper paint envelope curve and epoxy resin if will realize intellectuality.According to the data introduction, light is refined 10,000 tons of cold-reduced silicon sheets palpus power consumption 100,000,000 degree, is equivalent to the energy output in 1 year of two relatively large power plant.Then more valuable as for copper and epoxy resin; as seen; if alleviate or remove electric current and voltage transformer or directly reduce its cost; but can realize its function equally; then not only can reduce cost, promote effectively the process that grid automation is realized; and can save resource, energy-saving and emission-reduction protection environment, meaning is very great.In addition, because the PT volume is big, heaviness, install inconvenient attractive in appearancely, the more important thing is that the surge characteristic of general PT is bad, and the PT quantity of adorning when same electrical network is greatly the time, resonance takes place in circuit easily, explodes, causes serious life accident and power failure consequence thereby cause PT.
In addition, electric power circle to the network-building method that high-voltage switch gear adopts is usually at present:
1, use optical-fibre communications: disposable input cost was too high when this kind communication modes maturation but circuit were long;
2, utilize the GPRS communication: this kind mode also moves to maturity, but operation costs are too high.
In sum, present outdoor high-voltage switch of the prior art exists backward in technique, waste resource, defect of high cost.
