By the following examples, in conjunction with the accompanying drawings the utility model is further described.
Embodiment:
Referring to accompanying drawing 1,2, present embodiment is arranged in parallel binary decoding circuit that is made of diode array D1-D40 and relay J 1-5 and the binary-coded decimal decoding circuit that is made of diode array D31-D70 and relay J 6-J10.
As shown in the figure, gear signal conversion receiving circuit is set, comprises that conversion receives receiver socket U10, U1-1 and the U1-10 of " corresponding one by one " gear signal and " individual-ten " gear signal, and transfer relay J11-J15.
In the present embodiment, the corresponding 11-19 line that inserts the decoding circuit diode array of socket U1-1, transfer relay J11-J15 coil tandem is to socket U1-10 output; Socket U10 output line connects transfer relay and switches the contact common port, it is corresponding with described transfer relay normally-closed contact that what connect is the 1-10 line of diode array, corresponding connection with described transfer relay normally opened contact be the 11-19 line of diode array.
In concrete the enforcement, the 1-10 core of transformer gear signal input socket CZ is fixedly connected to U10.For " corresponding one by one " type gear signal, the 11-19 core of socket CZ is attached to the U1-1 socket with plug; And for " individual-ten " type gear signal, the 11-19 core of socket CZ is attached to U1-10 with plug.
In the course of work, when the gear signal of input is " corresponding one by one " type, its 1-10 shelves link by normally closed contact J11B, J11C, J12B, J12C, J13B, J13C, J14B, J14C, J15B and the J15C of transfer relay J11-J15 and the incoming line 1-10 of diode array respectively, and its 11-19 gear incoming line 11-19 direct by socket U1-1 and diode array links.When the gear signal of input is " individual-ten " type, because its ten bit line is connected in coil J11A, J12A, J13A, J14A, the J15A loop of transfer relay, when the transformer gear less than 10 the time, each transfer relay is failure to actuate, the normally closed contact of gear signal by transfer relay links with the incoming line 1-10 of diode array respectively: work as the transformer gear more than or equal to 10 the time, each transfer relay coil gets electric, and the normal opened contact of gear signal by transfer relay links with the incoming line 11-19 of diode array respectively.
After diode array receives the transformer gear signal,, signal is delivered on the output line of relevant diode array, realized decoding function according to the logic of its setting according to the incoming line of the diode array at input signal place.
As shown in Figure 1, 2, the output of diode array drives relay J 1-J10, at the binary-coded decimal of the binary code of relay tip J1B, J2B, J3B, J4B, J5B output and J6B, J7B, J8B, J9B, J10B output, deliver to the terminal board of this device, use for other automatics; In addition, the active binary-coded decimal signal of J6C, J7C, J8C, J9C, J10C output is delivered to show circuit, for the usefulness that shows the transformer gear.
The active binary-coded decimal conversion of signals that decoding drive integrated circult T1, T2 shown in Fig. 1 sends decoding circuit here becomes " seven segment code " signal, deliver to seven segment code display led 1, LED2 through current-limiting resistance R1-R14, show the current gear of transformer on-load voltage regulating shunting switch.
Referring to Fig. 1,3, be provided with in the present embodiment and rise relay SJ, pressure regulation by pressure regulation and fall relay J J and pressure regulation and stop relay TJ and constitute voltage regulator control circuit, and pressure regulation is risen relay SJ connect mutually with normally-closed contact and coil that relay J J falls in pressure regulation.
Press for the mistuning that prevents artificial or other automatics, blocking relay BSJ is set, its normally closed contact series connection is arranged on that pressure regulation rises relay SJ and pressure regulation is fallen in the wire loop of relay J J.Under the situation of transformer misoperation or accident, blocking relay BSJ coil gets electric, and its normally closed contact disconnects, and enters " pressure regulation liter " and " pressure regulation is fallen " blocking.
