3, the electric-control system of brick embryo forming machine

See Figure 21, the block diagram of the utility model electric-control system is shown.Electric-control system comprises control panel 300, the input termination distribution box 200 of control panel 300, and export the motor 001 of termination brick embryo forming machine, this control panel 300, when distribution box 200 output current, can drive the motor 001 as AC load to operate; The first earth element 310 and the second earth element 320 is accessed at the two ends of this control panel 300 respectively, lightning current is introduced the earth, improves the fail safe of system thus.

The present embodiment comprises secondary lightning protection circuit, and specifically the first earth element 310 is closed spark gap, and between the input being connected to control panel 300 and earth terminal, lightning current of can releasing can reach 20KA; Second earth element 320 is discharge tube, between the output being connected to control panel 300 and earth terminal, the fraction thunder-strike current flowing through control panel 300 is discharged further, namely a current limliting is remake to the residual voltage entering motor 001, make it lower than specified safe range.This just can make most of thunder-strike current be released by the first earth element of control panel 300 input, the second earth element that control panel 300 output is arranged then can make the residual voltage entering load less, thus be conducive to preventing load to be struck by lightning, improve its safety in utilization, extend its useful life.

The first above-mentioned earth element, the second earth element all can select the earth resistance of Zinc-oxide piezoresistor or other type to replace, and have good lightning protection effect equally.When lightning current is larger, Zinc-oxide piezoresistor is breakdown, and lightning current flows into earth terminal through Zinc-oxide piezoresistor rapidly, and the residual voltage entering motor 001 is clamped in preset range.

See Figure 22, the electrical principle block diagram of the utility model control panel is shown.In the major loop of this control panel 300, three phase mains input line L1, L2, L3 are connected to motor lines U1, V1, W1 of the three phase electric machine of motor 001 through major loop circuit breaker Q F1, A.C. contactor KM; In control loop, the input termination three phase mains input line L2 of control loop circuit breaker Q F2, L3, one of control loop circuit breaker Q F2 exports terminals of termination A.C. contactor KM coil, and another output of control loop circuit breaker Q F2 connects another terminals of A.C. contactor KM coil through inching button SB (1-3).Press inching button SB, A.C. contactor KM coil obtains electric adhesive, and the three-phase main contacts of A.C. contactor KM closes, and motor obtains electric operation, driven equipment work.The time pinning inching button SB is motor crawl duration of runs.Unclamp inching button SB, A.C. contactor KM coil blackout discharges, and the three-phase main contacts of A.C. contactor KM disconnects, and motor dead electricity shuts down, and driven equipment stops.

In order to make lightning current flow through safely in the present embodiment, all connected by shielded type cable between each circuit element, its terminals are screwed, and below further illustrate.

See Figure 23, represent the earthing mode of shielded type cable 330.This shielded type cable 330 is made up of cable core and cable shield, and this cable shield wraps cable core to reduce electromagnetic interference.

Figure 23 illustrates the mode of connection of shielded type cable 330 between distribution box 200 and control panel 300, this shielded type cable 330 passes through the first earth element 310 ground connection near one end cable shield of distribution box 200, and shielded type cable 330 is near the direct ground connection of other end cable shield of control panel 300.

In practical power systems, the length of shielded type cable 330 is generally greater than 20m, and the first earth element 310 therefore can be made to be connected to the position of distance feeder ear (distribution box) 4m ~ 6m.This first earth element 310 can be earth resistance, and particular type can be (certainly also can be other element) such as Zinc-oxide piezoresistors.The resistance of this earth resistance is equal with the equivalent resistance of the cable shield of shielded type cable 330, also can choose separately according to actual conditions.

Ground connection between motor 001 and control panel 300 can refer to aforesaid way, that is: shielded type cable 330 is near one end cable shield of control panel 300 by the second earth element 320 ground connection, and shielded type cable 330 is near the direct ground connection of other end cable shield of motor 001.

In this embodiment, between control panel 300 and distribution box 200, the shielded type cable 330 between motor 001 and control panel 300 have employed 2 grounding schemes, thus still maintains the good anti-jamming effectiveness of tradition 2 grounding schemes; Because shielded type cable 330 passes through earth element ground connection near one end cable shield of distribution box 200, be conducive to earth current or interference current limliting, the danger of screen is burnt when thus avoid earth-current or disturb excessive, also can reach electromagnetic compatibility effect preferably simultaneously, and negative antenna effect can not be caused.

See Figure 24, represent the concrete structure of the utility model shielded type cable.Be provided with many heart yearns 335 in the external protection 331 of this shielded type cable 330, wherein every root heart yearn is enclosed with inner protective layer 333; Especially, in external protection, 331 layers are provided with cable shield 332, and the inner side of inner protective layer 333 is provided with heart yearn screen 334.

Because the heart yearn of shielded type cable 330 and cable self all arrange screen, the interference in interference between heart yearn and the external world can be suppressed, specifically: the heart yearn of shielded type cable all devises heart yearn screen, the electromagnetic radiation being conducive to suppressing to produce between heart yearn, electrostatic coupling and electromagnetic induction; Cable self arranges cable shield, is conducive to suppressing outside electromagnetic interference; These two aspects factor, eliminates the interference that dynamical system shielded type cable produces preferably, is conducive to the accuracy ensureing data.

Preferably, the two ends ground connection respectively of cable shield 332 and heart yearn screen 334, effectively to reduce interference source.More preferably, be make cable shield 332 and heart yearn screen 334 near one end of distribution box 200 by the first earth element 310 ground connection, cable shield 332 and or heart yearn screen 334 near the direct ground connection in one end of motor 001.

The brick embryo forming machine that the utility model provides and subsystem or parts, can at least improving product quality, enhance productivity and environmental protection and energy saving some in improve systematic function, its structure is simple, and compact in design, cost is lower, has good market prospects.

Although the utility model with preferred embodiment openly as above; but it is not for limiting the utility model; any those skilled in the art are not departing from spirit and scope of the present utility model; can make possible variation and amendment, the scope that therefore protection range of the present utility model should define with the utility model claim is as the criterion.
