Technique scheme has following beneficial effect: it is low that this brassboard has cost, and purposes is wide, uses the advantages such as flexible.
Above-mentioned explanation is only the general introduction of technical solution of the present invention, in order to better understand technological means of the present invention, and can be implemented according to the content of instructions, below with preferred embodiment of the present invention and coordinate accompanying drawing to be described in detail as follows.The specific embodiment of the present invention is provided in detail by following examples and accompanying drawing thereof.
Accompanying drawing explanation
Fig. 1 is embodiment of the present invention structural representation.
Fig. 2 is embodiment of the present invention star triangle starting main circuit.
Fig. 3 is embodiment of the present invention star triangle start control circuit.
Embodiment
Below in conjunction with accompanying drawing, the preferred embodiments of the present invention are described in detail.
As shown in Figure 1, brassboard is controlled in a kind of motor star triangle starting, and it comprises: 1 fuse, 2 contactor KM1,3 contactor KM2,4 contactor KM3,5 time relays, 6 electrothermal relays, 7 buttons, 8 terminal rows, 9 power supplys, 10 motor.Described fuse, described contactor, the described time relay, described electrothermal relay, described button, described terminal row, be fixed on an experimental substrate by stationary installation, forms brassboard.Described power supply is three-phase alternating-current supply, and it is connected by wire with described terminal row; Described motor is phase asynchronous AC motor, and the two ends of its every phase winding are connected with described terminal row by wire.
Motor is selected phase asynchronous AC motor, power supply is three-phase alternating current, during System Implementation, three-phase supply L1, L2, L3 are connected to terminal row, the three-phase of phase asynchronous AC motor six terminal U1, V1, W1 and U2, V2, W2 are connected respectively to terminal row.Phase asynchronous AC motor Y-Δ starting circuit is divided into main circuit and control circuit, and main circuit and control circuit power supply are accessed by terminal row, during System Implementation, terminal row supply terminals are connected to one end of fuse.Main circuit power is three-phase supply, and control circuit power supply is selected the two-phase of appointing in three-phase supply.
As shown in Figure 2, main circuit is controlled in the starting of star triangle, and it is mainly by threephase switch QS, and fuse FU, contactor KM1 main contacts, contactor KM2 main contacts, contactor KM3 main contacts, electrothermal relay FR thermal element and threephase asynchronous form.Main circuit mainly completes that asynchronous motor is star-like to be connected with triangular form, and during starting, advanced planet-shaped connects starting, proceeds to triangular form running status after time delay.As seen from the figure when contactor KM1 and the conducting of contactor KM2 main contacts asynchronous motor in star-like connection, when contactor KM1 during with the conducting of contactor KM3 main contacts asynchronous motor in triangular form, be connected.First star-like connection reduced voltage starting during starting, then triangular form connects total head operation.
As shown in Figure 3, star triangle start control circuit, is mainly used in realizing system and controls requirement, presses start button SB2, contactor KM1 and contactor KM2 coil electricity, the star-like connection reduced voltage starting of motor; Time relay KT time delay fixed length is after the time, contactor KM1 and contactor KM3 coil electricity, and motor triangular form connects total head operation.Need be by thermal relay normally closed contact FR, stop button SB1 normally closed contact string in the middle of control circuit for realizing above-mentioned control function, start button SB2 normally opened contact and the self-locking of contactor KM1 coil, the conducting simultaneously of contactor KM2 and contactor KM3 coil, so need be by its electrical interlocks.The time relay starts during from the conducting of KM1 coil regularly, and timing is to cutting off KM2 coil power supply branch road, and self-locking conducting KM3 path of winding completes that asynchronous motor is star-like is connected to the switching that triangular form connects.
When student's real training or textual criticism; the main circuit and the control circuit that need hand assembled star triangle starting circuit; first main circuit is incorporated into three-phase supply one end of fuse by terminal row while installing; contactor KM1, KM2, KM3 complete the connection of star-like and triangular form; again by the thermal element string of electrothermal relay in the middle of main circuit, for asynchronous motor overload protection.When control circuit is installed, power supply is taken from two-phase in three-phase supply, can directly from one end of main circuit fuse, connect.Button is installed, and can first button internal circuit be connected, and afterwards corresponding leading point is connected to connecting terminal block.The time relay is selected the on-delay type time relay, and the time relay is installed on a pedestal, then pedestal is installed on experimental substrate.
After all circuit install and check and pass through, the operation of can switching on, check circuit actual motion effect, if successfully realize the starting of star triangle, reaches experimental real-training object; If not, need to check modification circuits, then carry out commissioning test, until controlling, the system that successfully realizes requires.
Brassboard is directly installed components and parts, there is no encapsulation and integration, has both reduced experimental cost, is conducive to again student and understands better circuit working principle.Brassboard is simulated Industry Control scene completely, and needs student manually to complete assembly manipulation, is conducive to improve student's operative skill level.Brassboard, except completing star triangle real training and textual criticism, can also be realized the training of the circuit such as crawl control, rotating control, sequential control, and purposes is very extensive.
A kind of motor star triangle the starting above embodiment of the present invention being provided is controlled brassboard and is described in detail; for one of ordinary skill in the art; thought according to the embodiment of the present invention; all will change in specific embodiments and applications; in sum; this description should not be construed as the restriction to invention, and all any changes of making according to design philosophy of the present invention are all within protection scope of the present invention.
