Description
Technical field
The utility model relates to electric equipment field, is specifically related to a kind of hv filtering building-out capacitor cabinet.
Background technology
In AC three-phase electric power system, the capacity current of employing capacitor carrys out the inductance current of compensates electric net, realize compensation lagging reactive power, improve power factor (PF), adjust network voltage, reduce line loss, the meritorious output of raising system or transformer, and then reach energy-saving and cost-reducing, the object of regulated power quality, reactor, as reactive power compensation means, is indispensable in electric power system.Series reactor is conventionally also referred to as damping reactor, and it is the reactor being connected in series with capacitor group or closely packed capacitor group, shoving while operating in order to limit switch.And the reactor adopting in existing power network, be in fact one without the air core coil of permeability magnetic material, volume and take up room large, cost is high, more complicated is installed, and harmonic wave is had to amplification, to electromagnetic interference is many, increased the pollution to electrical network of harmonic current that rectification unit produces around.
Utility model content
The purpose of this utility model is to overcome the defect existing in prior art, provides a kind of simple in structure, easy for installation, and volume is little, good heat dissipation, and can suppress the hv filtering building-out capacitor cabinet of harmonic current.
For achieving the above object, the technical solution of the utility model is to provide a kind of hv filtering building-out capacitor cabinet, comprise capacitor group, series reactor and discharge coil, described series reactor comprises coil, described coil winding is on tri-phase iron core, described tri-phase iron core is fixed between upper frame, lower folder frame, and one end of described series reactor is connected with three capacitor groups and discharge coil respectively.Wherein, series reactor parameter and capacitor parameters form coupling, can harmonic carcellation in compensation, traditional method is to adopt air-core reactor, bulky, be unfavorable for installing, and on-the-spot installation difficulty is also large, floor space also large this programme capacity reactance can be arranged on cabinet inside, and transportation is installed and all facilitated.
In order to guarantee the normal work of series reactor, reduce its temperature, preferably technical scheme is, and described iron core bottom is provided with refrigerating module, and described refrigerating module is fixed on heat dissipation base.
Preferred technical scheme is, the cabinet of described capacitor box consists of incoming line cabinet, the first capacitor box, the second capacitor box and the 3rd capacitor box, described series reactor is arranged on incoming line cabinet bottom, and described three capacitors are separately positioned on the first capacitor box, the second capacitor box and the 3rd capacitor box bottom.Such layout has been avoided by cabinet layering, conserve space.
In order to be easy to install and maintain, preferably technical scheme is, described incoming line cabinet bottom is provided with adjustment seat, and described series reactor is arranged in adjustment seat.
Preferred technical scheme is that institute's incoming line cabinet rear portion is also respectively arranged with the earthing switch blade being connected with capacitor group.When maintenance capacitor, by three-phase shortcircuit ground connection, guarantee maintenance safety.
In order to reduce in-cabinet temperature, preferred technical scheme is in described incoming line cabinet, also to comprise cooling fan.
Preferably technical scheme is, is also provided with temperature sensor on described series reactor, and described temperature sensor is connected with circuit breaker by control module.This device has increased temperature sensor at the Connecting line joint place of series reactor; by temperature sensor, carry out electrical connector temperature in detecting box; when temperature sensor collects after signal; by circuit, pass to control module; transmit again trip signal and drive its circuit breaker to disconnect electrical loop, protect the power equipment in cabinet, realize the temperature of cabinet inside and control; the safety of protection internal power equipment, the while has also increased the useful life of power equipment.
Advantage of the present utility model and beneficial effect are: the utility model adopts iron core series reactor, and magnetic circuit mainly, in iron core, is compared the air-core reactor of same capacity, has reduced the volume of reactor, leakage field, and nominal loss, and absorb harmonic wave; And the utility model is simple in structure, good heat dissipation effect, volume is little, also has the security control elements such as temperature, can increase the fail safe of cabinet internal power element, the useful life of the equipment that simultaneously increases electric power.
