Abstract
The utility model relates to an anti-harmonic capacitor and especially to a cabinet-style anti-harmonic capacitor. The cabinet-style anti-harmonic capacitor comprises a cabinet, an intelligent measurement and control device, a switching switch, capacitors, and series reactors. The capacitors are connected with the series reactors. The capacitors and the series reactors are fixedly arranged at the bottom of the cabinet. A separator plate is disposed on the center of the cabinet. The intelligent measure and control device and the switching switch are fixed to the separator plate. The above structure replaces a combined structure formed by discrete members including a reactive controller, a fuse, a composite switch or mechanical contactor, a thermal relay, a low-voltage power capacitor, and an indicating lamp which are connected through wires in the cabinet and on the surface of the cabinet. The structure of the anti-harmonic capacitor is simplified to a structure with a few modules. The cabinet-style anti-harmonic capacitor is simple in structure, small in size, simplified in wiring form, and equipped with a heat-dissipating hole and an exhaust outlet so as to achieve a good heat-dissipating effect.
Description
Technical field
The utility model relates to a kind of anti-harmonic wave electric capacity, especially a kind of case type anti-harmonic capacitor.
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, reduce 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. install Shunt Capacitor Unit concentratedly at substation busbars; 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.
Frequency converter in 0.4KV distribution system at present, high-frequency heating, heating in medium frequency, electric welding machine, use Deng equipment is more and more, in equipment running process, can produce more than 3 times harmonic waves like this, this harmonic wave can make the electric current in capacitor amplify, have a strong impact on the useful life of capacitor, common way is to install series reactor and parallel capacitor additional, control the switching quantity in parallel of power capacitor by reactive factor controller, thereby realize the compensation of reactive power, make power factor reach 0.95 left and right.But there is wiring complexity, 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 case type anti-harmonic capacitor is provided.
The utility model solves the technical scheme that its technical problem adopts: a kind of case type anti-harmonic capacitor, comprise cabinet, intelligent monitoring device, fling-cut switch, capacitor, series reactor, capacitor is connected with series reactor, capacitor, series reactor are fixedly installed on cabinet bottom, in the middle of cabinet, a dividing plate is set, intelligent monitoring device, fling-cut switch are fixed on dividing plate.
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, capacitor and series reactor are fixed on base plate, dividing plate is arranged on the top of capacitor and series reactor, dividing plate is provided with respectively the mounting groove with fling-cut switch, intelligent monitoring device adaptation, and fling-cut switch, intelligent monitoring device are fixed in mounting groove.
Of the present utility modelly further be set to: side plate is provided with exhaust outlet, thermovent, exhaust outlet setting corresponding to intelligent monitoring device, thermovent setting corresponding to capacitor.
Of the present utility modelly further be set to: described louvre is arranged and formed according to circular array by louvre.
Said structure substitutes and is connected by wire with cabinet face in cabinet by loose mails such as reactive controller, fuse, combination switch or mechanical contactor, thermal relay, low voltage power capacitor, indicator lights in prior art and forms structure, by extremely several modules of designs simplification, simple in structure, volume is little, simplify connection type, and being equipped with louvre and exhaust outlet, radiating effect is fine.
