It should be noted that first module control circuit and the total part of second unit control circuit, Such as, coil TBR had both been positioned in first module control circuit, was positioned at again in second unit control circuit. First module power supply circuits and second unit power supply circuits share a part, such as, coil TBK both positions In first module power supply circuits, it is positioned at again in second unit power supply circuits.
Such as, when the three-phase bus of first module side is powered, owing to the coil of VDR2 does not the most also have Having electric, the normally-closed contact of VDR2 Guan Bi, the coil of VDR1 obtains electric, corresponding all of of VDR1 Normally opened contact closes, i.e. control circuit loop path in Fig. 2 is: V101-416A-416C-VDR2 Coil-the VDR1 of normally-closed contact-416E-VDR1 the first normally opened contact-416G-auxiliary relay TBR Second normally opened contact-N100.
Now, owing to the coil of auxiliary relay TBR obtains electric, thus auxiliary relay TBR first Normally opened contact closes, due to TBR the first normally opened contact and VDR1 the 3rd normally opened contact and TBK Coils connected in series in current supply circuit, so when TBR the first normally opened contact and VDR1 the 3rd normally opened touch When point all closes, current supply circuit is energized, and the coil of TBK obtains electric, so that the TBK's in Fig. 1 touches Put electric, i.e. the three-phase bus of first module and the three-phase bus of second unit is through, and whole train is real Existing through power supply.
It should be noted that this relay of TBR function as an auxiliary reclay, pass through It is electric that the contact of this auxiliary reclay drives the coil of TBK to obtain.TBK is realized by auxiliary reclay Control circuit and the isolation of power supply circuits: all of Rule of judgment meet after make TBR coil come Obtain electric, auxiliary relay the first normally opened contact TBR is gone here and there before TBK coil power supply, by auxiliary Relay the 3rd normally opened contact TBR is helped to go here and there before TBK coil power supply, accordingly even when TBK line The power of circle is bigger, and power supply circuits can also bear.Without TBR as auxiliary reclay, Whole TBK control circuit likely bears bigger electric current, control with relay VDR1, VDR2, The contact of TBCOR, EMODR1 flows through big electric current for a long time and easily causes adhesion fault, reasonably selects Select the parameter of TBR, the reliability of circuit can be effectively improved.
Further, since the normally-closed contact two ends of VDR2 are parallel with TBR the second normally opened contact, work as TBR Coil obtain electric after, TBR the second normally opened contact close, now, due to the TBK closing of contact, VDR2 Coil obtains electric, and VDR2 normally-closed contact disconnects, TBR the second normally opened contact Guan Bi realize self-sustaining and supply Electricity.
The power supply circuits corresponding with second unit with control circuit due to the power supply circuits of first module and control Circuit symmetrical processed is identical, and therefore operation principle is the most identical with annexation, as shown in Figure 2.
In like manner, when the three-phase bus of second unit is powered, it is also possible to by the control that second unit is corresponding Circuit processed and power supply circuits make the closing of contact of TBK, and the power supply of second unit penetrates into first module Three-phase bus, it is achieved the through power supply of whole train.
It is described in detail below in conjunction with Fig. 2.
When the coil of VDR2 obtains electric, all normally opened contacts Guan Bi corresponding for VDR2, VDR2 in Fig. 2 Three normally opened contacts that relay is corresponding, the action simultaneously of these three normally opened contact.
When V101A and N100A powers, due to VDR1 coil the most not electric, therefore VDR1 Normally-closed contact Guan Bi, now VDR2 the first normally opened contact Guan Bi, the coil of TBR obtains electric, second The control circuit energising of unit, the loop of the control circuit of second unit is: V101A-416B-416D-VDR1 normally-closed contact-416F-VDR2 the first normally opened contact-TBR coil -VDR2 the second normally opened contact-N100A.
Now, owing to the coil of TBR obtains electric, TBR the 3rd normally-closed contact and TBR the 4th are normally closed tactile Point all closes, and power supply circuits turn on, and the passage path of the power supply circuits of second unit is: TBR the 3rd Normally opened contact-VDR2 the 3rd normally opened contact-416J-TBK coil-VDR2 the second normally opened contact -N100A。
TBK coil obtains electric, so that the TBK normally opened contact Guan Bi in Fig. 1, the power supply of second unit Penetrate into first module, it is achieved whole train power supply.
In like manner, when VDR1 coil obtain electric after, VDR1 normally-closed contact disconnect, normally opened by TBR the 4th Contact provides path, it is achieved self-sustaining is powered.
It addition, in the power supply circuits of first module, including VDR1 the 3rd normally opened contact and TBR One normally opened contact series connection, it is therefore an objective to when the power supply of first module is broken down, the first confession can be excised Electricity circuit, prevents that the power supply of second unit is counter to be poured on first module power supply circuits.Such as, when first Unit VDR1 fault, for protective relay and power supply circuits, needs to disconnect chopper TBKCN1, If not increasing the normally opened contact of VDR1 and VDR2, when TBR obtain electric after, normally opened contact close, The power supply of so TBKCN2 will from the normally opened string of TBR to the lower section of chopper TBKCN1, Cause the chopper TBKCN1 of disconnection the most charged.
The normal of VDR2 it addition, connected in the control circuit loop of first module in this utility model Closed contact, the normally-closed contact of the VDR1 that connected in the control circuit loop of second unit.Such Purpose is to realize interlock protection logic, when first module and second unit put into power supply simultaneously, Owing to voltage and the phase sequence of three-phase bus when two unit put into power supply are not necessarily identical simultaneously, If blindly TBK Guan Bi scaling loss may be assisted electrical equipment, if now Unit two are powered simultaneously, Directly TBK circuit will be blocked.VDR1 normally-closed contact and VDR2 normally-closed contact simultaneously switch off, TBK does not closes, such that it is able to effectively protection auxiliary electrical equipment.
In addition, it is necessary to explanation, the first isolation circuit breakers TBKCN1 and second isolation in Fig. 2 Chopper TBKCN2 the most all closes.Isolation A.C. contactor excision/reset relay TBCOR the most also closes.Urgent traction state relay EMODR1 is the most also Guan Bi.Therefore, TBKCN1, TBKCN2, TBCOR and EMODR1 can be connected on control In the loop of circuit.
When first module is powered, need to meet following condition:
VDR1 obtains electric;Train is without isolation A.C. contactor excision instruction output, i.e. TBCOR relay It is not excited;TBKCN1 breaker closing;Train is not in urgent traction state, i.e. EMODR1 Relay is not excited.
When second unit is powered, need to meet following condition:
VDR2 obtains electric;Train is without isolation A.C. contactor excision instruction output, i.e. TBCOR relay It is not excited;TBKCN2 breaker closing;Train is not in urgent traction state, i.e. EMODR1 Relay is not excited.
The above, be only preferred embodiment of the present utility model, not makees this utility model any Pro forma restriction.Although this utility model is disclosed above with preferred embodiment, but it is not limited to This utility model.Any those of ordinary skill in the art, without departing from technical solutions of the utility model scope In the case of, technical solutions of the utility model are made many by the method and the technology contents that all may utilize the disclosure above Possible variation and modification, or it is revised as the Equivalent embodiments of equivalent variations.Therefore, every without departing from this reality By the content of new technique scheme, according to technical spirit of the present utility model to made for any of the above embodiments any Simple modification, equivalent variations and modification, all still fall within the range of technical solutions of the utility model protection.
