The beneficial effects of the utility model are: a kind of novel change distribution three-phase imbalance adjustment dress provided by the utility model It sets and is provided with tri- road IGBT driver of Liang Kuai, primary another piece conduct of one piece of conduct is spare, damages in primary three roads IGBT driver Bad when, changes to spare three roads IGBT driver to concern is cut, is ensureing the electric system with three-phase imbalance regulating device just Normal stable operation, is additionally provided with environment regulating device, the problems such as temperature is excessively high and timely occurs in box house convenient for monitoring It adjusts, further ensures the environment of power system stability operation, especially extend the service life of three road IGBT drivers.
Detailed description of the invention
Fig. 1 is a kind of structural representation of novel change distribution three-phase imbalance adjustment device provided by the embodiment of the utility model Figure;
Fig. 2 is a kind of working principle of novel change distribution three-phase imbalance adjustment device provided by the embodiment of the utility model Figure.
Specific embodiment
In order to make the purpose of the utility model, technical solutions and advantages more clearly understood, below in conjunction with attached drawing 1,2 and in fact Example is applied, the present invention will be further described in detail.It should be appreciated that specific embodiment described herein is only used to solve The utility model is released, is not used to limit the utility model.
As shown in Figure 1, a kind of novel change distribution three-phase imbalance adjusts device, including a cabinet 1, in the cabinet 1 The bottom left in portion is equipped with triple line leading-in box 2, and the top of the triple line leading-in box 2 is connected with breaker 3, the cabinet It is provided with wire casing 4 on the right side wall of 1 inside, the middle position inside the cabinet 1 is equipped with crossbearer 5, is fixed on the crossbearer 5 Current sensor 6, main controller 8, closes 9, control panel 10 to incision at voltage collector 7, and 1 inner upper of cabinet, which sets up separately, to be equipped with Detection module 11 and two pieces of mounting plates 12 are exported, are separately installed with a three road IGBT drivers 13 on every piece of mounting plate 12, two Be isolated among a three roads IGBT driver 13 by partition 14, the input terminal of described two three roads IGBT drivers 13 with it is described Output detection module 11, the main controller 8 are connected to by the conducting wire in wire casing 4 by conducting wire connection, output end to pass 9 is cut It is connect with the control panel 10, current sensor 6, voltage collector 7 by conducting wire, the control panel 10 is also connected with environment tune Regulating device.
Referring to Fig. 2, under normal circumstances, tri- road IGBT driver of Liang Kuai, one piece as primary another piece as spare, to cutting Switch is connected with primary three roads IGBT driver, is connected into triple line from the triple line leading-in box of the application device, conducting wire connection is disconnected Road device plays the role of serious overload or short circuit and the failures such as under-voltage to protect circuit, then passes through the intracorporal current sense of case Device accesses three-phase line real-time detection three-phase current, current sensor by collected current information issue the main controller of connection into Row processing, main controller is closed with controller, to incision, voltage collector is connected, and voltage collector also accesses three-phase line, main controller Current information can be analyzed, find the current imbalance state of system, while calculating three-phase current and reaching equilibrium state The current value of required conversion calculates after completing, and controller drives IGBT to act by primary IGBT drive circuit, and output is mended It repays electric current and determines output current data by exporting detection module, so that three-phase current is all redistributed, and system Three-phase total current remain unchanged.
When primary three roads IGBT driver breaks down or damages, output detection module detects that abnormal electric current is defeated Out, current sensor collects abnormal circuital current information and feeds back to main controller, and main controller feeds back information to control panel, Control panel control guarantees circuit stability operation, former spare three tunnel to pass is cut to the side for switching to spare three roads IGBT driver IGBT driver becomes new primary three roads IGBT driver, dismantles lower former primary three roads IGBT driver from mounting plate thereafter Replacement is repaired, while fault message is passed back to backstage by control panel.
As a kind of specific structure of novel change distribution three-phase imbalance adjustment device, as depicted in figs. 1 and 2, institute Stating environment regulating device includes temperature sensor 15, refrigerator 16 and fan 17, is equipped with one piece of mesh plate below the crossbearer 5 18,18 bottom of mesh plate is equipped with downwards several refrigerators 16, corresponds to the refrigerator on the bottom plate in the cabinet 1 16 position is equipped with soakaway trench 19, and there are two the settings of fan 17 and is separately mounted in 1 left and right sides wall of cabinet The top position in side, the position that the fan 17 is corresponded on the outside of the cabinet 1 are provided with exhaust duct 20.The environment adjusts dress Setting further includes humidity sensor 21.The control panel 10 is also connected with wireless module 22.
It is provided with environment regulating device, the problems such as temperature is excessively high occur in box house convenient for monitoring and is adjusted in time, when Temperature sensor detects case body temperature, transfers data to control panel, under normal circumstances, opens fan, cabinet bottom There is air inlet hole in portion.If temperature is excessively high, control panel control starting refrigerator and fan, refrigerator bottom out of cabinet are delivered up Hot gas is extracted out from box house and is discharged by exhaust duct by cold air, fan, and the water outlet and soakaway trench of refrigerator pass through pipe A small amount of condensed water of road connection, generation is discharged from soakaway trench.Caused by generating heat when can will so be run in cabinet due to each component High temperature lower, ensure that environment suitable needed for power system stability operation, extend the use of three road IGBT drivers Service life.Humidity sensor is further increased in cabinet, and further the intracorporal humidity of case is monitored, avoids humidity in case excessively high It endangers, refrigerator is turned off when reaching humidity threshold, increase fan exhausting dynamics, it can also be to avoid when the intracorporal humidity mistake of case Occurs electrostatic phenomenon when low.
Finally by wireless module by the data of temperature sensor, humidity sensor, current sensor, voltage collector with And alarm is transferred to and has accessed in wireless equipment, facilitates that staff is intuitive, dynamic management data.
The above is only the preferred embodiment of the utility model only, is not intended to limit the utility model, all at this Made any modifications, equivalent replacements, and improvements etc., should be included in the utility model within the spirit and principle of utility model Protection scope within.
