Description of drawings
Fig. 1 is the theory diagram of the high-power Industrial Frequency Transformer soft starting device of the utility model;
Fig. 2 is the circuit diagram in soft starting device shown in Figure 1 loop.
Embodiment
Fig. 1 represents the theory diagram of the high-power Industrial Frequency Transformer soft starting device of the utility model.High-power Industrial Frequency Transformer soft starting device is connected between power supply and the controlled transformer T, and it comprises total power supply circuit breaker CB and soft start control unit SC, and control unit SC mainly comprises high-power current-limiting resistance R and the soft start switch K in parallel with it.During work, total power supply circuit breaker CB closes, begin is to give high-power Industrial Frequency Transformer T charging by high-power current-limiting resistance R, the former limit pressure drop of transformer T is risen, the reactance of the former limit of transformer T increases, the electric current that flows through resistance R is more and more littler, the soft start switch K that closes again this moment, and then transformer T enters the normal power supply running status.
The circuit in soft starting device loop shown in Figure 2 is an example that is used for the soft start of three-phase high-power transformer T1.Soft start switch K1B among the soft start control unit SC is an A.C. contactor, and the two ends of three high-power current-limiting resistance R1, R2, R3 are in parallel to 11 and 12,21 and 22,31 and 32 with three main contactss of A.C. contactor K1B respectively.K2 is a time-delay relay, connects with line bag K1A by its timing closing contact.
Switch A, B among total power supply circuit breaker CB2, C connect to corresponding main contacts 11,21,31 in 11 and 12,21 and 22,31 and 32 with three main contactss of A.C. contactor K1B respectively.Three-phase C, the B of three-phase high-power transformer T1, A connect to other three corresponding main contactss 12,22,32 in 11 and 12,21 and 22,31 and 32 with three main contactss of A.C. contactor K1B respectively.
The A1 end of line bag K1A is connected to the switch C among total power supply circuit breaker CB2, and the other end A2 of line bag K1A is connected to normally opened contact 11 ends of time-delay relay K2, and its other end 12 is connected to the A2 end of time-delay relay K2 line bag and is connected to zero line N together.
When starting working, switch A, B, the C of total power supply circuit breaker CB2 that closes power on for transformer T1 by high-power current-limiting resistance R1, R2, R3 respectively.Because switch C also is connected with time-delay relay K2, so after the switch of total power supply circuit breaker CB2 closes, delay time the several seconds approximately, the normally opened contact of time-delay relay K2 is just closed, line bag K1A is got, then make A.C. contactor K1B adhesive, its main contacts is to closing, and this moment, high-power transformer T1 entered the normal power supply running status.High-power transformer T1 is connected with machine D through its contact H ', C ', B ' and A '.
The power supply of the high-power Industrial Frequency Transformer soft starting device of the utility model is a civil power, and high-power current-limiting resistance generally adopts the resistance of 100W10～20 Ω, the sort of A.C. contactor that A.C. contactor K1B should select for use its capacity and high-power transformer capacity to be complementary.The time-delay of A.C. contactor K1B is advisable to set for 3～5 seconds.After adopting soft starting device, every maximum mutually stream electric current that starts equals to import phase voltage U/R.
The high-power Industrial Frequency Transformer soft starting device of the utility model is not only applicable to can also be used for the soft start of single-phase transformer in the soft start of the cited three-phase high-power transformer of the utility model.Total power supply circuit breaker CB2 of this moment adopts the IP circuit breaker, and A.C. contactor K1B can all can with pair of contact or with three pairs of contact parallel connections.
Specific embodiment of the present utility model has provided detail circuits fundamental diagram, main circuit structure.For persons skilled in the art,, can not exceed the protection range of present specification description and claims standard not deviating from operation principle of the present utility model and using any conspicuous change of under the prerequisite it being done.
