Description of drawings
Fig. 1 is the structural principle block diagram according to a kind of clinker production line of the utility model technological scheme kiln tail fan controller.
Embodiment
With reference to explanation accompanying drawing 1, a kind of clinker production line kiln tail fan controller comprises the frequency variator that is used to drive kiln tail blower fan, and is the regulator cubicle of said frequency variator distribution.
About the selection of frequency variator and since the kilneye blower fan employed all be high pressure like 6kv or 10kv, former high voltage converter, by silicon controlled rectifier, devices such as thyristor inversion constitute, harmonic wave is big, and is all influential to electrical network and motor.In recent years, some new devices that grow up (like IGBT etc.) change this present situation, the high voltage converter that constitutes thus, excellent performance can be realized the PWM inversion, and it is little not only to have harmonic wave, and power factor also has significant improvement.
At present; A large amount of low voltage frequency converter manufacturers is arranged at home; Its major part is the middle low power product of AC380V, and can develop, produces and provide the high voltage converter manufacturer of service, and the indivedual enterprises (as: closing Kang Yisheng) that possess the capacity of scientific research or financial strength of minority are only arranged.Along with developing rapidly of domestic high voltage converter industry; Homemade main flow high voltage converter has reached international standards at aspects such as function, reliabilities; Then occupying very big advantage aspect cost and the service, present homemade high voltage converter occupancy surpasses 60%, has improved the transmission level of China's industry greatly; Promoted the variable frequency energy saving reforming of industry-by-industry, especially used more in steel works, waterworks and power station.
The high voltage converter of the overwhelming majority all belongs to friendship orthogonal type frequency variator at present, and the difference of pressing the used energy-storage travelling wave tube of intermediate dc link can be divided into voltage-source type and current source type.
The advantage of current source type frequency variator is that energy can feedback grid, can realize four quadrant running.Mains side often adopts the three-phase bridge scr rectification circuit, and input current harmonics is bigger, and input power factor is generally lower, shuts down easily when voltage ripple of power network is big.The voltage-source type high voltage converter is owing to adopt the uncontrollable rectification of diode, and input power factor is higher relatively, and is not subject to the influence of voltage ripple of power network, and in the poor application of electrical network condition, therefore, the voltage-source type high voltage converter is the first-selection of this programme.
Said regulator cubicle contains independently the transformer case that output connects said frequency variator, and institute uses transformer to be isolating transformer, and the frequency variator input voltage can satisfy the requirement of different electrical network electric pressures usually.For technological transformation project, original motor power frequency operation owing to can not change motor usually, install frequency variator additional after, require the output voltage of frequency variator consistent with line voltage.
Said regulator cubicle also comprises the power cell cabinet that is exclusively used in the installation power unit, avoids the influence of other high tension apparatus, helps reasonable distribution simultaneously.
Further; In order more to help power transmission and distribution, said regulator cubicle also comprises the bypass cabinet of the independent direct-connected kiln tail blower fan that is provided with, and this bypass cabinet and said converter circuit also connect; Drive the power supply of kiln tail blower fan after said frequency variator is out of service, to switch to power frequency, with the continuity that guarantees to produce.
Said Electric Appliance Cabinet also comprises the switching cabinet of string between said frequency variator and institute's driving kiln tail blower fan, to switch the kiln tail blower fan that frequency variator drives.
Said power cell cabinet is provided with sink, and the ventilation flue of this sink is arranged on the rear portion of power unit cabinet, and ventilation flue is provided with dust filtering device, avoids abominable industrial and mineral to influence the normal operation of power cell.More specifically, power cell cabinet rear portion is a ventilation flue, and cool air is through the front cabinet door filter layer, and the unit radiator of flowing through takes the heat that produces in the power cell to the after ventilation road, by cabinet top centrifugal blower hot air is discharged to outside the unit cabinet.Cabinet is equipped with filter layer outdoors, and it is inner to be used to stop that dust gets into the unit.
Said power cell cabinet be provided with position limit switch with normally closed interlock, wherein said normally closed interlock string is on the main circuit of an alarm device, when closing the Over-The-Counter door, normally closed interlock breaks off, and is then closed when opening the cabinet door, thereby can when being not intended to open, report to the police.
In said power unit cabinet, the three-phase of power cell input connects the secondary output of transformer, and string has fus, with the normal operation to device protection is provided.
Further, the cabinet of said transformer case top is provided with cooling blower, and is equiped with the temperature controlling instrument that temperature warning and overtemperature protection are provided on the cabinet door.
In addition, said transformer case cabinet door is provided with the position limit switch with normally closed interlock, and wherein said normally closed interlock string is on the main circuit of an alarm device.
