The operation principle of above-mentioned zoom interlock protection circuit unit 401 is as follows:
Zoom is regulated motor M 1 for adopting the DC(direct current) direct current machine of 12V work, zoom amplification during output+12V, zoom dwindles during output-12V.
SW1 and SW2 are ZSW amount input terminals.SW1 characterizes and amplifies the input of ZSW amount, and SW2 characterizes and dwindles the input of ZSW amount.
OUTPUT A and OUTPUT B are two output electrodes for the zoom electrode power supply.When no ZSW amount is imported, zoom output 0V; When SW1 amplifies input, zoom output+12V; When SW2 dwindles input, zoom output-12V.
Its principle is as follows:
Key in SW1, can make the action of first dpdt relay: first cutter (moving contact) 206 contacts with first normally opened contact 2051 and (also is, the pin 13 of first dpdt relay is connected) with pin 9, second cutter (moving contact) 208 contact with second normally opened contact 2071 (pin 4 of first dpdt relay is connected with pin 8).
And key entry SW2, can make the action of second dpdt relay: the 3rd cutter (moving contact) 211 contacts with the 3rd normally opened contact 2101 and (also is, the pin 13 of second dpdt relay is connected) with pin 9, four blade (moving contact) 213 contact with the 4th normally-closed contact 2122 (pin 4 of second dpdt relay is connected with pin 8).
And; first dpdt relay and second dpdt relay constitute the interlock protection loop; as SW1 and SW2 simultaneously effectively the time; first dpdt relay and second dpdt relay have only one can work; that is: the dpdt relay that in advance triggers is taken the lead and is pinned the loop; make follow-up input switch amount invalid, thereby protected distribution system.
For example; when first dpdt relay 201 is taken the lead when effective; the pin 13 of first dpdt relay 201 disconnects with pin 11 and is connected (also namely first cutter 206 is connected with 2052 disconnections of first normally-closed contact); thereby cut off the power supply of the pin 16 of (second dpdt relay 202) second relay coil 214; therefore second dpdt relay 202 can not be worked, thereby has protected distribution system.
Or; when second dpdt relay 202 is taken the lead when effective; the pin 4 of second dpdt relay 202 disconnects be connected (also namely four blade 213 is connected with 2122 disconnections of the 4th normally-closed contact) with pin 6; cut off the power supply of (first dpdt relay 201) first relay coil 209 pins 16; therefore first dpdt relay 201 can not be worked, thereby has protected distribution system.
In summary, when one of them dpdt relay gets an electric shock when losing efficacy, the relay coil of another dpdt relay can not obtain feed, thereby therefore akinesia has eliminated the dangerous sign or phenomenon of distribution system short circuit.
It below only is preferred implementation of the present utility model; should be pointed out that for those skilled in the art, under the prerequisite that does not break away from the utility model principle; can also make some improvements and modifications, these improvements and modifications also should be considered as protection range of the present utility model.
