At present, common intelligent capacitor primary side is all to access general supply by wire on the market, if wire does not have Compress, spark phenomenon easily occur.

Utility model content

The purpose of this utility model is to overcome the deficiencies in the prior art part there is provided a kind of easy-to-connect, safeguards simple Novel bus interconnection system intelligent capacitor filtering compensation device.

The utility model solves the technical scheme that is used of technical problem：

A kind of novel bus interconnection system intelligent capacitor filtering compensation device, including zero fling-cut switch, capacitor, controller And display, zero fling-cut switch, reactor, capacitor and controller are installed in housing, controller connects zero fling-cut switch, zero Fling-cut switch linked reactor, reactor two capacitors of series connection, two capacitors are in parallel, and display is embedded in before housing, is shown Show that device connects controller, two 485 communication interfaces, two 485 communication interfaces connection controller, in shell are formed with the rear wall of housing Body lateral wall installs bus-type fuse, and bus-type fuse one end is connected with zero fling-cut switch, in the other end and compensating cabinet Copper bar is connected.

Moreover, the housing is prolate cube.

Moreover, installing micro-transformer of current between zero fling-cut switch and reactor.

Moreover, being respectively mounted temperature sensor on capacitor and reactor, fan is installed in case inside wall, temperature is passed Sensor controls the closure or openness of fan by controller.

Moreover, zero described fling-cut switch is the combination of relay or controllable silicon or relay and controllable silicon.

Advantage of the present utility model and good effect are：

1st, this capacitor filtering compensation device accesses general supply by bus-type fuse, and without connecting wire, reduction connects Point, production hour is reduced, and can be transported with split, the quick assembling in scene when using, it is not necessary to which professional can safeguard.

2nd, this capacitor filtering compensation device built-in temperature sensor, reacts overvoltage of capacitor, crosses harmonic wave, leaks electricity and flow through Capacitor internal the degree of heat when big and environment temperature is too high, realizes overheat protector.

3rd, this capacitor filtering compensation device can many building block systems use, can by be currently needed for economic capability prepare, It can be extended in the future by situation, realize stage design flood, prepared adjustment can easily carry out capacity using scene, realize idle benefit Repay optimization.

4th, this capacitor filtering compensation device, which has, suppresses filtering except harmonic wave function, effectively suppresses higher hamonic wave and shoves, To higher hamonic wave formation low impedance path.There is the absorption effect of releasing to harmonic wave, can influence of the Eliminate highter harmonic to capacitor, guarantor Protection circuit and capacitor overload, prevent capacitor from overheating, dielectric aging, self-healing property declines, service life reduction.
