Description
Technical field
The utility model relates to a kind of reactive power compensator, especially a kind of intelligent low-pressure filtering compensation device with isolation compensating unit of independent switching control.
Background technology
In the electrical network, inductive loads such as motor occupy quite great proportion in modern times, and they also absorb a large amount of reactive powers when consuming active power.Reactive power not only causes generator output to descend, and reduces equipment for power transmission and distribution efficient, decreases but also increased net, has a strong impact on power supply quality.
The effective way that addresses these problems is carried out reactive power compensation exactly, and reactive power compensation has formed the more reactive power compensation device of kind through the development of many decades.Early stage reactive-load compensation equipment adopts the compensation method of fixed capacitor group or integrated capacitor more because of reasons such as load background and control technologys.Because compensation capacity can't be regulated automatically, to owe when causing system's high load capacity to mend, the phenomenon of crossing benefit during underload happens occasionally; The stable operation of the system of giving brings very big influence; And along with the development of modern industrial technology, the capacity of production equipment is in continuous increase; Their input and to withdraw from the reactive power fluctuation that electrical network is caused also more and more serious has further increased the weight of compensation equipment in system's passive situation that causes in service.
Commonly used is autocompensation installation now, still, and in this scope of low-voltage compensation; Traditional autocompensation installation all is that fling-cut switch, capacitor, reactor etc. are installed in the cabinet, is regardless of at interval, and one group is broken down; Cause the accident easily and spread, and one group of maintenance, must stop the primary power source of package unit; Compensation is stopped, influencing the power factor of this system.
The utility model content
To above-mentioned deficiency; The utility model provides a kind of intelligent low-pressure filtering compensation device with isolation compensating unit of independent switching control; Not only the compensating unit of respectively organizing with autocompensation installation has carried out isolating setting, and every group of compensating unit can independently carry out switching control and maintenance.
In order to address the above problem; The utility model adopts following technical scheme: a kind of intelligent low-pressure filtering compensation device; Comprise cabinet and the bus unit, control unit and the multi-channel compensating system unit that are arranged in the cabinet, said compensating unit is connected with the bus unit through control unit; It is characterized in that said cabinet is a drawer unit formula structure, said control unit and every road compensating unit are separately positioned in the drawer unit.
Further, said compensating unit comprises reactor, air circuit, fling-cut switch and the capacitor of series connection successively, and said reactor is connected with the bus unit through control unit.
Further, the said front panel that is provided with the drawer unit of control unit is provided with the control panel of nameplate and control unit.
Further, the said front panel that is provided with the drawer unit of compensating unit is provided with capacitor switching indicator light and power factor meter.
The beneficial effect of the utility model is: the utility model passes through traditional compensation arrangement modularization; Components and parts such as every group/every phase secondary capacitor, fling-cut switch, air circuit and reactor are installed in the independent drawer unit space; Not only the compensating unit of respectively organizing with autocompensation installation has carried out isolating setting; And every group of compensating unit can independently carry out switching control and safeguard, have little, the novel structure of taking up room, multiple functional, use flexibly, characteristics such as reliable in quality and production are simple and easy.
Description of drawings
Fig. 1 is the structural representation of the utility model;
Fig. 2 is the structural representation of the said compensating unit of the utility model;
Wherein, the control panel of the drawer unit of the drawer unit of 1 cabinet, 2 control units, 3 compensating units, 31 binding posts, 32 reactors, 33 air circuits, 34 fling-cut switches, 35 capacitors, 4 nameplates, 5 control units, 6 capacitor switching indicator lights, 7 power factor meters.
Embodiment
As depicted in figs. 1 and 2, a kind of intelligent low-pressure filtering compensation device of the utility model comprises cabinet 1 and the bus unit, control unit and the multi-channel compensating system unit that are arranged in the cabinet, and said compensating unit is connected with the bus unit through control unit; Said cabinet is a drawer unit formula structure, and said control unit and every road compensating unit are separately positioned in the drawer unit.Said compensating unit comprises reactor 32, air circuit 33, fling-cut switch 34 and the capacitor 35 of series connection successively, and said reactor 32 is connected with control unit through binding post 31.The said front panel that is provided with the drawer unit 2 of control unit is provided with the control panel 5 of nameplate 4 and control unit.The said front panel that is provided with the drawer unit 3 of compensating unit is provided with capacitor switching indicator light 6 and power factor meter 7.
The performance characteristics of the utility model:
1, adopt intelligentized low-voltage capacitance fling-cut switch, merged the advantage of controllable silicon and A.C. contactor, the electric arc that is produced when neither having the electromagnetic relay energising, the power consumption harmonic when not having the noncontacting switch long-term work is again polluted.Have the silicon control zero-cross switching in switching moment, during normal the connection, have the advantage of the no power consumption of contact.
2, adopt the Single-chip Controlling switching, the operation conditions of intelligent monitoring input power supply and load, thus have perfect defencive function:
1) voltage failure open-phase protection: during the power supply of system voltage phase shortage, the switch refusal is closed;
2) supply voltage open-phase protection: during the power supply of working power phase shortage, the switch refusal is closed, connects the back if the phase shortage automatic disconnection occurs;
3) self diagnosis error protection: if break down, then refusal is closed;
4) no-load protection: the switch refusal is not closed when inserting load;
5) power-failure protecting: after the connection, have a power failure automatic disconnection if meet suddenly.
This novel system has been broken the tactic pattern of existing imaginary power automatic compensation; Have excellent function such as capacitor zero switching and simple for structure, same cabinet and can adorn characteristics such as more capacitances, capacity are can degree of adjustment big; Every intelligent low-pressure filtering compensation system has operating condition indication and demonstration, and the manual switching action button.The utility model compact conformation, be convenient to design, production and operation maintenance, and the capacity adjustability is good.
