Abstract
The utility model discloses a special zero passage switching vacuum contactor of hot stove low pressure reactive compensation in ore deposit, including compensation controller, control module and vacuum contactor, control module passes through compensation controller detection circuitry's electric current and voltage signal, and the time point that vacuum contactor dropped into or amputated is calculated and control in closing the separating brake time of record contactor. The utility model discloses realized not only that capacitor bank can the voltage zero passage put through, it is disconnected that the zero is crossed to the electric current to greatly promoted the capacity of switched capacitor group, the switching quality of condenser has been improved to the advantage separately of having synthesized blend switch and vacuum contactor, has eliminated the influence of switch to the system, life -span of extension switch and power capacitor.
Description
Technical field
The utility model relates to a kind of vacuum contactor, specifically the special operating passing zero vacuum contactor of a kind of ore furnace low-pressure reactive compensation.
Background technology
In mine heat furnace smelting system, generally use low-voltage reactive compensator capable, be used for promoting and gain merit, improve smelting quality.Current low-voltage reactive compensator capable commonly uses switching capacitance switch two classes, and one is jumbo contactor, and another kind is the combination switch that controllable silicon and contactor compose in parallel.Can be used for jumbo Capacitor banks with contactor, shortcoming to eliminate inrush phenomenon and arcing, is unfavorable for capacitor for voltage protection group.Use device with Capacitor Switched by Compound Switch group, can prevent inrush phenomenon and arcing, but shortcoming is the restriction of combination switch due to structure, capacity is less, can not be used for jumbo capacitor group switching, causes to take up room excessive, and loop is too much, and system is too complicated.
Summary of the invention
The purpose of this utility model is to provide a kind of ore furnace low-pressure reactive compensation special operating passing zero vacuum contactor, to solve the problem proposed in above-mentioned background technology.
For achieving the above object, the utility model provides following technical scheme:
The special operating passing zero vacuum contactor of a kind of ore furnace low-pressure reactive compensation, comprise compensating controller, control module and vacuum contactor, described control module passes through electric current and the voltage signal of compensating controller testing circuit, the on/off switch time of record contactor, calculate and the time point controlling vacuum contactor input or excise.
As the utility model further scheme: described compensating controller is idle compensating control.
Compared with prior art, the beneficial effects of the utility model are: the utility model not only achieves Capacitor banks energy voltage zero-cross and connects, current over-zero disjunction, and the significant increase capacity of institute's opening-closing capacitor bank, combine the respective advantage of combination switch and vacuum contactor, improve the switching quality of capacitor, eliminate the impact of Switch Controller system, extend the life-span of switch and power capacitor.
Accompanying drawing explanation
Fig. 1 is the schematic block circuit diagram of the special operating passing zero vacuum contactor of ore furnace low-pressure reactive compensation.
Embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, be clearly and completely described the technical scheme in the utility model embodiment, obviously, described embodiment is only the utility model part embodiment, instead of whole embodiments.Based on the embodiment in the utility model, those of ordinary skill in the art are not making the every other embodiment obtained under creative work prerequisite, all belong to the scope of the utility model protection.
Refer to Fig. 1, in the utility model embodiment, the special operating passing zero vacuum contactor of a kind of ore furnace low-pressure reactive compensation, comprise compensating controller, control module and vacuum contactor, described control module passes through electric current and the voltage signal of compensating controller testing circuit, the on/off switch time of record contactor, calculate and the time point controlling vacuum contactor input or excise.
Described compensating controller is idle compensating control.
Operation principle of the present utility model is: refer to Fig. 1, control module testing circuit electric current, voltage signal, the on/off switch time of record contactor, calculates the time point that vacuum contactor drops into or excises.In time dropping into Capacitor banks, controller closes a floodgate and says the word to control module, the voltage signal of control module by detecting, calculate the difference of arrival time in voltage zero moment and vacuum contactor contactor closing time, determine closing time point, ensure vacuum contactor closing time just in time with voltage zero moment arrival time consistency, ensure that vacuum contactor dropped in the voltage zero moment, avoid shoving of producing when Capacitor banks drops into.In time excising Capacitor banks, controller sends out separating brake order to control module, the current signal of control module by detecting, calculate the difference of arrival time in current zero moment and vacuum contactor contactor closing time, determine closing time point, ensure vacuum contactor closing time just in time with current zero moment arrival time consistency, ensure that vacuum contactor is in the excision of current zero moment, avoids vacuum contactor arcing.The switching device structure be connected in other loop in voltage reactive compensation device of submerged is identical, so only introduce the capacitor group switching device in single loop.
To those skilled in the art, obvious the utility model is not limited to the details of above-mentioned one exemplary embodiment, and when not deviating from spirit of the present utility model or essential characteristic, can realize the utility model in other specific forms.Therefore, no matter from which point, all should embodiment be regarded as exemplary, and be nonrestrictive, scope of the present utility model is limited by claims instead of above-mentioned explanation, and all changes be therefore intended in the implication of the equivalency by dropping on claim and scope are included in the utility model.Any Reference numeral in claim should be considered as the claim involved by limiting.
In addition, be to be understood that, although this specification is described according to execution mode, but not each execution mode only comprises an independently technical scheme, this narrating mode of specification is only for clarity sake, those skilled in the art should by specification integrally, and the technical scheme in each embodiment also through appropriately combined, can form other execution modes that it will be appreciated by those skilled in the art that.
