As shown in Figure 1, a kind of electrical maintenance implementation training station, including workbench, be equipped on the workbench: air is opened
Pass, main contactor, electrothermal relay, fuse, button, asynchronous motor, connecting terminal block, transformer, the time relay, relay
Device, change-over switch, toggle switch, voltmeter, ammeter, indicator light, household socket, fluorescent lamp, home switch, copper wire line, electricity
Sub-ballast, ballast, starter.Air switch is no less than two, and main contactor is no less than three, and electrothermal relay is no less than two
A, fuse be no less than six, button switch be no less than three.The time relay is no less than two, relay is no less than
Two, toggle switch be no less than two.
The workbench uses irony bilayer matt fine groove plastic-spraying structure, and work top is fire prevention, waterproof, anti-electric bakelite
Plate.
Following preparation is carried out before use:
1. check training station on each component installation whether properly and securely, it is each whether be connected firmly, power socket with
Whether the wiring number between component corresponds.
2. 2 megaohms should be cannot be less than with the insulation against ground resistance of 500V megohm meter measurement training station.
Embodiment 2
As shown in Figures 2 and 3, a kind of electrical maintenance implementation training station can be realized the threephase asynchronous of button interlocking
Positive and negative rotation control, including workbench, are equipped on the workbench: main contactor group, button switch group and asynchronous motor,
Middle main contactor group includes the first main contactor and the second main contactor, and button switch group is pressed including the first button switch, second
Button switch and third button switch, each button switch all have a normally opened contact and a normally-closed contact；First main contact
After device is in parallel with the normally opened contact of the first button switch, connect with the normally-closed contact of the second button switch, the second main contactor with
After the normally opened contact of second button switch is in parallel, connect with the normally-closed contact of the first button switch.It also sets on the workbench
There are electrothermal relay and fuse.
As shown in Fig. 2, when needing to change the steering of motor, as long as directly pressing reversion button, it is not necessary to first press
Stop button.This is because if motor has pressed forward rotation direction operating, what coil was switched on.At this moment if pressing lower button SB2,
Normally closed interlock of the SB2 string in KM1 wire loop disconnects first, and KM1 wire loop is disconnected, is equivalent to and presses stop button
The effect of SB3, stalls motor, and the normally open contact closure of subsequent SB2, the circuit of closing coil KM2 makes power phase phase
Instead, motor reversely rotates.Equally, when motor has reversely rotated, if pressing SB1, motor is just first stalled and is rotated forward afterwards.
When the route is using button actions, normally closed first disconnection, normally opened rear the characteristics of being closed, guarantee that KM1 and KM2 will not be powered simultaneously,
Thus the interlocked control of motor forward/backward rotation is realized.So the normally closed interlock of SB1 and SB2 is also referred to as locking contact.
As shown in figure 3, selecting the devices such as QF, FU, KM1, KM2, FR, SB1, SB2, SB3 and XT on table top.Each terminal
Numerical system have two kinds: 1) use device terminal actual number, example: KM1 1,3,5,13, A1；The 95 of FR；SB 1. 2. 3. 4.
Deng.2) use device terminal artificial number, 1,3, the 5 of example FU, 1,2 etc. of indicator light.The existing practical volume of the terminal of general device
It number should preferentially use, because number inherently illustrates the structure of element.1 and 2,3 and the 4 of example KM1 represent normally opened main contact；SB
1. with 2. represent normally closed button, 3. with 4. represent normally opened button.
Detection and debugging: after confirmation wiring is correct, AC power source is connected, presses SB1, motor should rotate forward；SB2 is pressed, electricity
Machine Ying Fanzhuan；SB3 is pressed, motor should stall.If cisco unity malfunction, it should analyze and debug.
Embodiment 3
As shown in Figure 4,5, electrical maintenance implementation training station can be realized the unidirectional crawl of asynchronous motor and starting control, packet
Workbench is included, is equipped with main contactor, button switch group and asynchronous motor on the workbench, wherein button switch group includes
First button switch, the second button switch and third button switch, each button switch all have a normally opened contact and one
Normally-closed contact；Circuit one is in parallel with the normally opened contact of third button switch by the normally opened contact of the second button switch, circuit two by
The normally-closed contact of third button switch is connected with the normally opened contact of main contactor, after circuit one is in parallel with circuit two, is contacted with main
The normally-closed contact series connection of device coil, the first button switch.It is additionally provided with electrothermal relay and fuse on the workbench.
As shown in figure 4, the start-up course of route: pressing start button SB2, coil KM1, which is powered, to be attracted, and main contact closure connects
Energization motivation M power supply, motor M rotation；KM1 normally opened contact closure simultaneously constitutes latching circuit with SB3 (3-5), when release is pressed
When button, motor will not be stalled.Stopped process: pressing lower button SB1, the release of KM1 coil losing electricity, and motor stops.
Point operation control process: it presses point operation control button SB3, SB3 normally-closed contact SB3 (3-5) and first disconnects, cut off KM1's
Self-locking circuit；SB3 normally opened contact SB3 (3-4) is closed afterwards, and KM1 coil obtains electric actuation, electric activation operation, although KM1 at this time
(4-5) closure, but SB3 (3-5) has been disconnected, and KM1 cannot be self-locking.SB3 is unclamped, SB3 (3-4) is first disconnected, the release of KM1 power loss,
SB3 (3-5) is closed afterwards, and circuit restPoses, and is prepared for starting next time.
As shown in figure 5, selecting fuse FU, switch QF, contactor KM, electrothermal relay FR, button on device table top
The devices such as SB1, SB2, SB3 and connecting terminal block XT.
Detection and debugging: after confirmation wiring is correct, connecting AC power source L1, L2, L3 and simultaneously " close " switch QF, press SB2, electricity
Machine should start and continuous rotation, and pressing SB1 motor should stall, and physical cabling is as shown in the figure.Press SB3, motor running, pine
Open SB3, motor stalling.
If supply voltage drops to 320V or less or power cut-off, then contactor KM1 after pressing the operating of SB2 electric motor starting
Main contact will disconnect, motor stalling.Restoring voltage again is 380V (allowing ± 10% fluctuation), and motor would not voluntarily rise
It is dynamic --- there is under-voltage or o-volt protection.
Above embodiments are intended to indicate that the utility model, rather than limit the protection scope of the utility model, Suo You
The simple transformation made under conditions of without prejudice to the spirit of the present invention principle is each fallen in the protection scope of the utility model.
