Description
Technical field
Patent type of the present invention relates to rural power grids distribution line, is specifically related to a kind of rural power grids intelligent comprehensive power distribution equipment.
Background technology
Along with the gradual perfection of rural power grids, better meet resident's living safety electricity consumption, a kind of standardization, miniaturization, outdoor type low-voltage distribution equipment are provided, meet the compensation of operation maintenance, safety management, watt metering and the reactive power of rural power grids.For solving above specification requirement, the present invention has adopted intelligent environment-friendly type low-voltage capacitance fling-cut switch and totally digitilized reactive power compensation control device to interosculate, and reaches the requirement of national upgrading of rural power grids intelligent construction.
Specific implementation method
Intelligent comprehensive power distribution equipment adopts rainproof, dustproof, antitheft, anticreep, anti-lightning strike, anti-electromagnetic interference, adopts corrosion resistant plate.In casing, be divided into four parts: wire inlet unit, metering units, outgoing line unit, reactive compensation capacitor unit, its scheme of electric power is shown in accompanying drawing.
1, basement: wire leading method adopts casing side-face wire feeding, and special stainless steel waterproof elbow is set, and configures waterproof pad between elbow and casing.Wire inlet unit is comprised of the HD11 series isolation switch and the Intellectual leakage breaker that match with transformer capacity; according to < < rural area low-voltage power technical regulation > > regulation, alleviated the contradictory problems of total protection throwing property of leaking electricity.Intellectual leakage breaker adopts microprocessor intelligence digital programmable control circuit, and all functions complete by Single Chip Microcomputer (SCM) program; Automatic circuit residual electricity flow valuve, residual electricity flow valuve when fault leakage tripping phase sequence and demonstration tripping operation; Automatically follow the tracks of circuit residual current, automatically increase or reduce operating value gear, possess 485 communication interfaces, can transmit the operational factor of earth leakage protective device.
2, measuring room: multi-functional activereactive energy table and metering instrument transformer are arranged on metering units, separate with shrouding with other unit; Metering units is reserved line (primary line and secondary line) necessary passage (hole) only, adopt two storied gate, inside door is reserved metering observation window, and chamber door should be able to add lead sealing and locked, not only possessed anti-electricity-theft function, also facilitated the writing task of metrological personnel.
3, outlet chamber: feeder assembly adopts HD11 series isolation switch and high sublevel circuit breaker, can realize master and enter not off-position replacing transmission line circuit of unit, can not affect normal life, productive power.
4, reactive compensation capacitor chamber: adopted intelligent environment-friendly type low-voltage capacitance fling-cut switch and the combined pattern of totally digitilized reactive power compensation control device, switching cycle, first throw and first cut, phase-splitting grading compensation, can fine compensation to three-phase imbalance load, make the lifetime of equipment, reach the optimal compensation effect.
A, adopt intelligent environment-friendly type low-voltage capacitance fling-cut switch, merge the advantage of controllable silicon and relay, by controllable silicon and relay and connect, make combination switch there is silicon control zero-cross switching in the moment of switching, have again during normal connection and there is contactor idle; Controllable silicon and A.C. contactor have been made up in the deficiency of low-pressure reactive compensation application aspect.
Specific works principle: by reverse-blocking tetrode thyristor and relay and connect, realizing voltage zero-cross conducting and current over-zero cuts off, make combination switch there is silicon control zero-cross switching in the moment switching on and off, and after connection, possess the advantage of contactless contactor idle.During input, be the first triggering and conducting of controllable silicon when voltage zero-cross, stable after again by relay adhesive conducting, and be first relay to be left to controllable silicon delay zero-crossing to disconnect during excision, realize current over-zero excision.Adopt Single-chip Controlling switching, the operation conditions of intelligent monitoring controllable silicon, relay and input power and load, thus there is perfect defencive function.Voltage failure open-phase protection: during the power supply of system voltage phase shortage, switch refusal is closed; If occur after connection, phase shortage disconnects automatically.Supply voltage open-phase protection: during the power supply of working power phase shortage, switch refusal is closed; If occur after connecting, phase shortage disconnects automatically.
B, utilize totally digitilized reactive power compensation device, show in real time the information such as L1, L2, each phase power factor of L3, voltage, electric current, active power, reactive power, the total percent harmonic distortion of voltage, the total percent harmonic distortion of electric current, frequency, electric capacity output display and switching status alert.Controller is supported three-phase compensation, phase splitting compensation, comprehensive compensation scheme, can control program be set by menu, and interface adopts the man-machine LCD Chinese of large-screen liquid crystal display, total digitalization design, AC sampling.Hold/the coding such as capacitor switching control program support (1:2,1:2:3,1:2:4:8 ...) and fuzzy control switching mode; There is Rs485, MODBUS standard field bus communication interface, convenient access switch cabinet system.Factory's distribution monitoring system management software of apolegamy customization, pack user machine system into, be connected with controller communication port, can observe at computer display historical load curve and the form of on-the-spot real time data and custom system, field data is fast and easily provided for user is energy-saving and cost-reducing.
Rural power grids intelligent comprehensive power distribution equipment of the present invention can reach rainproof, dustproof, antitheft, anticreep, anti-lightning strike, anti-electromagnetic interference, and integrated inlet wire, outlet, metering, reactive power compensation are integrated.Basement all adopts insulating material sealing with the busbar surface that is connected of outlet chamber, has better guaranteed operator's safety.
