The utility model relates to an anti-harmonic capacitor, and specifically relates to an intelligent integrated power capacitor. The intelligent integrated power capacitor comprises a cabinet, an intelligent measurement and control device, a switching switch control unit, and four capacitors, wherein the four capacitors are arranged on the bottom of the cabinet; a separator is arranged in the middle of the cabinet; the intelligent measurement and control device and the switching switch control unit are fixed on the separator; the intelligent controller is connected with the switching switch control unit; and the switching switch control unit is connected with the capacitors. According o the utility mode, the structure of the intelligent integrated power capacitor is simplified into several modules, so that the power capacitor is simple in structure and small in size, and the wiring is simplified; and the power capacitor is provided with a temperature sensor which can indicate the heating inside the capacitor caused by over current, over harmonic, over electric leakage and over environment temperature, thereby achieving over-temperature protection. When the temperature exceeds a preset temperature, the switching switch control unit automatically disconnects the capacitors, and stops operation, thereby protecting the equipment.
Description
Technical field
The utility model relates to a kind of anti-harmonic wave electric capacity, especially a kind of Intelligent integration power condenser.
Background technology
Electric load in electrical network is as motor, transformer etc., and major part belongs to inductive load, and in running, needing provides corresponding reactive power to these equipment.After the reactive-load compensation equipments such as shunt capacitor being installed in electrical network, the reactive power that can provide inductive reactance to consume, reduced the reactive power that electric network source provides, carried by circuit to inductive load, owing to having reduced reactive power flowing in electrical network, therefore can reduce the electric energy loss because carrying reactive power to cause of circuit and transformer, carry out reactive power compensation.Reactive power compensation can improve power factor, is a wastage reducing and energy saving measure requiring less investment while yielding quicker results.
Reactive Compensation Mode conventional in electrical network comprises: 1. at substation busbars, install Shunt Capacitor Unit concentratedly; 2. in high and low voltage electric distribution circuit, disperse to install Shunt Capacitor Unit; 3. in distribution transformer low-pressure side and user workshop switchboard, parallel capacitor is installed; 4. shunt capacitor etc. is installed at single motor place.
Its drive motors of a lot of large-scale operating mode enterprises adopts 0.66KV at present, can reduce the input current of equipment like this, reduce the wastage, reactive power compensation at present conventionally adopts and installs parallel capacitor additional at power distribution room, by reactive factor controller, control the switching quantity in parallel of power capacitor, thereby realizing the compensation of reactive power, is that power factor reaches 0.95 left and right.Specifically by idle compensating control, switch with knifeshaped fuse, the actuator of reactive power compensator, thermal relay, series reactor, several parts such as power capacitor form.Exist wiring complicated, take up room large, the shortcoming such as cost is high, site examining and repairing inconvenience.
Summary of the invention
The purpose of this utility model is, a kind of easy for installation, wiring is simple, volume is little Intelligent integration power condenser is provided.
The utility model solves the technical scheme that its technical problem adopts: a kind of Intelligent integration power condenser, comprise cabinet, intelligent monitoring device, fling-cut switch control unit, four capacitors, four capacitors are fixedly installed on cabinet bottom, a dividing plate is set in the middle of cabinet, intelligent monitoring device, fling-cut switch control unit are fixed on dividing plate, intelligent controller is connected with fling-cut switch control unit, and fling-cut switch control unit is connected with capacitor.
Of the present utility modelly further be set to: described cabinet also comprises base plate, side plate, top cover, base plate, side plate, top cover surround cabinet jointly, in cabinet, be also provided with the temperature sensor corresponding with capacitor, temperature sensor is connected with fling-cut switch control unit.
Of the present utility modelly further be set to: also comprise rs-485 interface, rs-485 interface is arranged on cabinet, and is connected with intelligent monitoring device.
Said structure by designs simplification to several modules; simple in structure, volume is little, simplifies connection type; while set temperature transducer; can reflect capacitor overcurrent, cross harmonic wave, leakage current is excessive to be crossed in high situation and causes capacitor internal to generate heat with ambient temperature; realize over-temperature protection; after surpassing design temperature, fling-cut switch control unit excises capacitor automatically, and out of service, reaches protection equipment.
Accompanying drawing explanation
In order to be illustrated more clearly in the utility model embodiment or technical scheme of the prior art, to the accompanying drawing of required use in embodiment or description of the Prior Art be briefly described below, apparently, accompanying drawing in the following describes is only embodiment more of the present utility model, for those of ordinary skills, do not paying under the prerequisite of creative work, can also obtain according to these accompanying drawings other accompanying drawing.
Fig. 1 is the structural representation of the present embodiment;
Embodiment
Known with reference to figure 1, a kind of Intelligent integration power condenser, comprise cabinet 1, intelligent monitoring device 2, fling-cut switch control unit 3, four capacitors 4, four capacitors 4 are fixedly installed on cabinet 1 bottom, a dividing plate 11 is set in the middle of cabinet 1, intelligent monitoring device 2, fling-cut switch control unit 3 is fixed on dividing plate 11, intelligent controller 2 is connected with fling-cut switch control unit 3, fling-cut switch control unit 3 is connected with capacitor 4, described cabinet 1 also comprises base plate 12, side plate 13, top cover 14, base plate 12, side plate 13, top cover 14 surrounds cabinet 1 jointly, in cabinet 1, be also provided with the temperature sensor corresponding with capacitor 4 (not identifying in figure), temperature sensor is connected with fling-cut switch control unit 3, also comprise rs-485 interface 5, rs-485 interface 5 is arranged on cabinet 1, and be connected with intelligent monitoring device 2.
During the networking of many playscripts with stage directions utility model product, can automatically generate a network, system is carried out to reactive power compensation.As figure below, wherein a capacitance module is made as main frame, and reactive factor is calculated, and other several are made as slave, and main frame is controlled slave by the mode of 485 communications, thereby forms low-voltage reactive power automatic control system.If indivedual slaves break down, automatically exit, do not affect all the other work.If hostdown, also will exit, in all the other slaves, produce a new main frame, form a new system; The electric capacity that capacity is identical is pressed switching cycle principle, and the different electric capacity of capacity carries out switching by the suitable principle of mending.
Obviously, above-described embodiment is only used to done giving an example is clearly described, and the not restriction to execution mode.To those of ordinary skill in the art, can also make other changes in different forms on the basis of the above description.Here exhaustive without also giving all execution modes.And the apparent variation of being extended out thus or change are still in protection range of the present utility model.
