Background technology

In recent years, stepping up with factory automation degree and people's quality of life, more electric equipments are continuous It is employed to promote, user proposes the quality of power supply higher requirement.In low-voltage distribution system, because electrical equipment is continuous Increase so that the reactive current increase in power network, therefore, the electric energy consumed on electrical grid transmission circuit is consequently increased, finally Grid supply quality is caused to decline.In order to improve the stability of electric power system, it is ensured that power supply quality, the usual low pressure in user side Special reactive power compensator is installed in distribution system to reduce energy loss.

Intelligent low-voltage power capacitor is based on 2 (△ types) or 1 (Y types) low voltage power capacitor, using micro- The technological achievements such as electronics software and hardware technology, sensing technology, network technology and Electric Manufacture technology, by its integrated and intellectuality, with Accurate phase control mode realizes the operating passing zero of capacitor, and many Intelligent low-voltage power capacitors can lead to when being used together Communication or cascade two ways are crossed by requirement switching step by step is controlled, low-voltage reactive power automatic compensation function is realized, while being also equipped with three The safeguard measure such as phase excessively stream, under-voltage, over-pressed, temperature.There is Intelligent low-voltage power capacitor based on zero fling-cut switch power consumption to subtract Less, the high advantage of easy maintenance, compensation performance, has adapted to requirements at the higher level of the modern power network to reactive-load compensation.

At present, common intelligent capacitor is vertical on the market, although integrated level is also very high, but some capacitor box Dividing plate between the upper and lower away from smaller, vertical capacitor is not placed into.

Utility model content

The purpose of this utility model is to overcome in place of the deficiencies in the prior art that there is provided a kind of scientific structure design is rational Horizontal intelligent capacitor filtering compensation device.

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

A kind of horizontal intelligent capacitor filtering compensation device, including housing, breaker, zero fling-cut switch, reactor, electric capacity Device, controller and display, the housing are prolate cube, and breaker, zero fling-cut switch, reactor, electricity are installed in housing Container and controller, controller are fixed on the left side wall inner face of housing by support, and controller connects zero fling-cut switch, zero switching The binding post of switch one end linked reactor, other end connection breaker, reactor two capacitors of series connection, two capacitors are simultaneously Connection, breaker is packed in the rear wall inner face of housing, and breaker is connected with general supply by wire, is formed with the rear wall of housing Two 485 communication interfaces, two 485 communication interfaces connection controller is embedded in display, display connection control in the front side wall of housing Device processed.

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 housing rear wall inner face, temperature Spend the closure or openness that sensor controls fan by controller.

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

Moreover, being formed with heat emission hole in the leading flank of housing, trailing flank, left surface and right flank.

Moreover, described display is LED display.

Advantage of the present utility model and good effect are：

1st, this filtering compensation device designs for horizontal type structure, is different from the upright type of design of prior art, it is adaptable to up and down every The closely spaced capacitor box of plate.

2nd, this filtering compensation device built-in temperature sensor, reaction overvoltage of capacitor, crosses that harmonic wave, leakage current be excessive and ring Capacitor internal the degree of heat, realizes overheat protector when border temperature is too high.

3rd, this filtering compensation device can many building block systems use, can by be currently needed for economic capability prepare, in the future may be used Extended by situation, realize stage design flood, prepared adjustment can easily carry out capacity using scene, realize that reactive-load compensation is excellent Change.

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