Description
Technical field
The utility model relates to electric power accessory field, in particular to loaded capacity-regulated transformer.
Background technology
Transformer (Transformer) utilizes mutual inductance principle.Transformer utilizes the principle of electromagnetic induction to change the device of alternating voltage, and main member is primary coil, secondary coil and iron core (magnetic core).Major function has: voltage transformation, current transformation, impedance transformation, isolation, voltage stabilizing (magnetic saturation transformer) etc.
Powerful transformer is common in remote distance power transmission field.Usually after power plant sends electricity, the voltage of electric energy is strengthened by step-up transformer (multistage boosting), after long-distance transmissions, arrive electricity consumption place, then use step-down transformer that the voltage of electric energy is adjusted downward to operable amplitude through electric substation.Original transformer is the different turn ratios by main and sub-coil group (primary side, secondary side), realizes boosting and step-down by Current Mutual Inductance.But find when using, under different needs for electricity, the electric energy needing secondary side to provide is different, namely need the no-load loss solving transformer.
And then, in order to overcome this problem, there is capacitance-adjustable transformer.Capacitance-adjustable transformer is the important solutions reducing distribution transformer no-load loss, and this builds consensus already.The no-load capacitance-regulating transformer technical scheme that last century, the eighties proposed, needs distribution transformer power operation and operating process is loaded down with trivial details, thus makes no-load capacitance-regulating transformer substantially not play energy-conserving action in actual use.Loaded capacity-regulated transformer technology is arisen at the historic moment in the case, and it can automatically carry out the adjustment of transformer capacity to realize energy conservation object under not off-position.All the time, the emphasis that loaded capacity-regulated transformer realizes all has been placed in the research of loaded capacity-regulated switch and automatic capacity transfer control strategy, more conventional way introduces in the design of loaded capacity-regulated switch by loaded switch mentality of designing, by rationally arranging transition resistance to reduce overvoltage, the overcurrent in switching over process.

To loaded capacity-regulated be low capacity.The then first stage, the control switch K31 of primary side transition resistance R1 closes, and the control switch K32 of secondary side transition resistance R2 closes, but transition resistance R1 and R2 is respectively by K11 and K12 loop short circuit, and circuit is unchanged.
Second stage, K switch 11, K12, K13, K14 all disconnect, and transition resistance R1 forms primary side loop with coil III 1 and I 1, and transition resistance R2 forms secondary side circuit with coil III 2 and I 2.In this stage, select situation according to transition resistance (resistance), secondary load side voltage decreases, but uninterrupted power supply.
Phase III, K switch 21 and K22 close, and connect again, connect after resistance R2 and II 2 parallel connections with coil III 2 and I 2 again after transition resistance R1 and II 1 parallel connections with coil III 1 and I 1, and circuit voltage recovers normal.
K31 and K32 of fourth stage transition resistance all disconnects, and makes resistance R1 and R2 no longer place in circuit, and large low capacity conversion is complete.
Corresponding, rise the inverse process (adjusting, to improve capacity according to fourth stage, phase III, second stage and the order of first stage) that appearance process is said process.
Realize above-mentioned loaded capacity-regulated, need the loaded capacity-regulated switch of a supporting transition resistance, the mechanical type of loaded capacity-regulated switch as shown in Figure 2:
High and low pressure side is all deposited needs a set of independent capacity transfer main contact, in Fig. 2, and contact 13 and capacity transfer transition contact 14.In capacity transfer process existence 13 and 14 parallel operation capacity transfer simultaneously, transition contact 14 works independently, and capacity transfer terminates rear main contact 13 and works independently.Wherein transition contact is connected with transition resistance.
But in using, the use of capacity transfer main contact and switch (as K11, K12) there are certain requirements.

Below, the circuit shown for Fig. 4, illustrates the process that loaded capacity-regulated transformer provided by the utility model regulates capacity.
When normal work, bear whole loads by main capacitance-adjustable transformer (the first transformation group), now the 7th K switch 7, the 8th K switch 8 are in off-state.First K switch 1, the 3rd K switch 3, the 4th K switch 4 and the 6th K switch 6 are all closed, connect after making the second coil L2 and tertiary coil L3 parallel connection with the first coil L1 again, and connect with the first coil L1 after the 5th coil L5 and the 6th coil L6 parallel connection.
Carry out being adjusted to example be described so that capacity be descending, be divided into four-stage:
First stage, the 7th K switch 7 and the 8th K switch 8 of transition transformer (the second transformation group) close, and now, transition transformer is with main capacitance-adjustable transformer (the first transformation group) shared load in parallel.
Second stage, the first K switch 1, the 3rd K switch 3, the 4th K switch 4, the 6th K switch 6 all disconnect, and now main capacitance-adjustable transformer quits work completely, and load is born completely by transition transformer, and transition transformer is in overload in short-term.
Phase III, second switch K2 and the 5th K switch 5 all closed, main capacitance-adjustable transformer becomes low capacity, and load is from transition transformer and the main capacitance-adjustable transformer shared having become low capacity.
Fourth stage, the 7th K switch 7 and the 8th K switch 8 all disconnect, and namely transition transformer quits work, and only have main capacitance-adjustable transformer work.
The capacity of the first transformation group (main capacitance-adjustable transformer) is ascending to carry out regulating is that inverse process according to above-mentioned several stage carries out.
It should be noted that loaded capacity-regulated transformer provided by the utility model mainly make use of the advantage of transformer production producer, reduces the requirement to switch, the loaded switch of common maturation, and need not match with transition resistance and protective device.The utility model is on the basis of main transformer and connects a transition transformer, when former transformer carries out capacity conversion, plays temporal transition effect, thus makes main transformer can realize capacity conversion under not off-position.And the manufacture of transition transformer is obviously very easy to for transformer producer.
Except the adjustment using the connected mode as above-mentioned concrete switch and coil to realize capacity, it can also be loaded capacity-regulated transformer provided by the utility model, also comprise: be connected in series in the first set of main coils 101, and the main switch be connected between primary side positive terminal 1001 with primary side negative pole end 1002 and connecting with the second main coil 103 groups, and be connected to the transition switch between secondary side positive terminal 1003 and secondary side negative pole end 1004.
When main capacitance-adjustable transformer (the first transformation group) carries out capacity regulating, the work of the first transformation group can be stopped completely.As can by being connected in series in the first set of main coils 101, and the main switch be connected between primary side positive terminal 1001 and primary side negative pole end 1002 cuts off the connection between the first set of main coils 101 and both positive and negative polarity, certainly, control switch on the circuit at the first secondary coil group 102 place can be connected equally, cut-out first set of main coils 101 be connected between both positive and negative polarity in, cut off the connection between the first secondary coil group 102 and both positive and negative polarity simultaneously.
Same, also can increase control switch on 104 groups, the second secondary coil, with cut-out second main coil 103 groups be connected between both positive and negative polarity in, cut off the connection between 104 groups, the second secondary coil and both positive and negative polarity simultaneously.
In order to play the effect of capacity regulating, the first transformation group can be multiple, and each first transformation group includes first set of main coils 101 in parallel with the second main coil 103 groups and the first secondary coil group 102 in parallel with 104 groups, the second secondary coil.Namely in same loaded capacity-regulated transformer, there is multiple first transformation group and a second transformation group.
When multiple first transformation group works simultaneously, a part of first transformation group work selectively only can be allowed, thus pondage, certainly, also the while of can being multiple first transformation group, or part carries out the adjustment of capacity, and then completes the adjustment of total capacity.
Concrete, transition transformer just plays the effect of transition temporarily, and thus capacity can be less than the heap(ed) capacity of the first transformation group, can reduce the cost of transition transformer, and the capacity of the second transformation group is less than the capacity of the first transformation group.
Through concrete measuring and calculating, the capacity of the second transformation group can be 1/50-1/90 with the ratio of the heap(ed) capacity of the first transformation group.More specifically, the capacity of the second transformation group can be 1/60-1/80 with the ratio of the heap(ed) capacity of the first transformation group.
The capacity of the transition transformer adopted, be generally the jumbo 1/60-1/80 of capacitance-adjustable transformer, capacity transfer as 630kVA becomes the transformer that can adopt 10kVA, generally the transformer of 630kVA is 200kVA and 160kVA transformer according to the different Adjustable Capacity of connection, economic adjustment point is 80kVA-100kVA, transition transformer will have 10 times of short-time overloads, but according to the cooperation of switch each during capacity transfer, overload time can be 20-40ms, and transition transformer will be excised completely At All Other Times except capacity transfer comes into operation instantaneously, therefore initial temperature of transshipping is low, can meet the demands completely.Certainly, the second transformation group also can be the adjustable transformation group of capacity, and so the heap(ed) capacity of the second transformation group just should be the 1/60-1/80 of the first transformation group heap(ed) capacity.
Concrete, the heap(ed) capacity as the first transformation group is 630KVA, and the capacity of the second transformation group is 10KVA.This kind of set-up mode, or be 63:1 according to the first transformation group heap(ed) capacity and the second transformation pool-size ratio.
The utility model embodiment 2 provides three-phase loaded capacity-regulated transformer, as shown in Figure 4, comprising:
First transforming circuit and second transforming circuit in parallel with the first transforming circuit, the first transforming circuit comprises the second diverter switch and the second transformation group 202 that the first diverter switch of series connection and adjustable the first transformation group 201, second transforming circuit of capacity comprise series connection.
In fact, the effect played of the first transformation group 201 and the second transformation group 202 is when normally working respectively, bears transformation task, and when the first transformation group 201 switches, auxiliary first transformation group 201 bears transformation task.Therefore, can by arranging the first diverter switch K301 to control the first transformation group 201 and the second transformation group 202 whether place in circuit, (two ends herein comprise primary side two ends and secondary side two ends namely whether to access the two ends of power supply, about transformer, how place in circuit is this area routine techniques, do not repeat them here, it should be noted that, the first diverter switch K301 is when closing, and the effect that the first transforming circuit and the second transforming circuit play is identical).Wherein, the first transformation group 201 is connected between primary side positive terminal 1001 and primary side negative pole end 1002, and the second transformation group 202 is connected between secondary side positive terminal 1003 and secondary side negative pole end 1004.
As shown in Figure 4, can find out, the primary side of the first transforming circuit and the primary side (First Transition coil 203) of the second transforming circuit are in parallel, and the secondary side of the secondary side of the first transforming circuit and the second transforming circuit (the second transition coil 204) is also in parallel.First Transition coil 203 and the second transition coil 204 are controlled by the second diverter switch K302, to determine whether it is linked in circuit.
