Technical field
The utility model relates to a kind of nonpolarity input of oil seismic exploration collecting device power supply, the automatic dc power converter of fixed polarity output.
Background technology
Be imbedded in underground oil in order to seek, usually adopt the method for artificial earthquake, explore, artificial earthquake is exactly to dig a well on ground, explosive is arrived the shaft bottom down, ignition charge produces seismic wave, in order to gather and receive seismic wave, lay the earthquake private cable of some on the ground, wave detector, acquisition station, power supply station, the collecting devices such as special-purpose seismic instrument of record seismic signal.The now employed special-purpose seismic instrument in land, normally five kinds of collecting devices: i.e. U.S., France, the special-purpose earthquake instrument and equipment that three states such as Canada produce.Place of production difference, design is different, characteristics are respectively arranged, power supply station as IMAGE instrument produced in USA, the power supply connecting line, one is that a stubborn mouthful of joint connection other end, power supply station is that clip connection 12V storage battery is its power supply, and the power supply station will produce 5V in inside except that own electricity consumption, power supplys such as 48V, supply with other acquisition station work by the earthquake private cable, when the IMAGE power supply stands in field work, require battery voltage can not be lower than 10V, electric current is not less than 10A, electric power polarity is tighter, can not wrong, and the wrong electric power polarity will burn out the power supply station.
The utility model content
The purpose of this utility model is a kind of circuit of unidirectional conducting principle design according to diode, utilize the nonpolarity input of diode control relay adhesive conducting, the dc power converter of fixed polarity output solves the problem that burns out the power supply station because of the misconnection electric power polarity.
Scheme of the present utility model is: nonpolarity input fixed polarity output DC source converter, main building block comprises: four rectifier diode D1-D4, four relay J 1-J4, the output polarity joint pin, circuit is: 4 pin of relay are as the output of power supply, 2 pin of relay are imported as power supply, 4 pin of relay J 1 and relay J 4 are communicated with as the negative pole of transducer with lead exports the E point, 4 pin of relay J 2 and relay J 3 are communicated with as the positive pole of transducer with lead exports the C point, 2 pin of relay J 1 and relay J 3 are communicated with as the power supply of transducer with lead imports the A point, and 2 pin of relay J 2 and relay J 4 are communicated with the point as power supply input B with lead; 3 pin of relay J 1 connect the positive pole of diode D1, negative pole is succeeded electrical equipment J1,2 pin of relay J 3,1 pin of relay J 3 connects the negative pole of diode D3, positive pole is succeeded electrical equipment J1,2 pin of relay J3, relay J 1,1 pin of relay J 3 is with after 3 pin are connected with lead, be connected to relay J 2,2 pin of relay J 4,1 pin of relay J 2, connect the negative pole of diode D2, positive pole is connected to J2,2 pin of relay J 4,3 pin of relay J 4 connect the positive pole of diode D4, and negative pole is connected to relay J 2,2 pin of relay J 4, after 3 pin of relay J 2 and 1 pin of relay J 4 are communicated with lead, receive relay J 1,2 pin of relay J 3, relay J 1-J4 2 pin separately are communicated with 5 pin.
Operation principle: after input port A, B insert the 12V DC power supply, as: the A point is a power-polarity, and the B point is a positive source.Folk prescription conducting principle according to diode, pull-in winding adhesive under diode D1 conducting of the relay J 1 of nonpolarity input fixed polarity output DC source converter, input 2 pin and 4 pin conductings by relay J 1 are delivered to the output of E point to the negative pole of power supply, the pull-in winding of relay J 3 is ended and not conducting by diode D3, after the B point added positive source, relay J 2 pull-in windings were at diode D
2Adhesive under the conducting. input 2 pin of relay J 2 and 4 pin conductings are delivered to the output of C point to the positive pole of power supply, the pull-in winding of relay J 4 is ended and not conducting by diode D4, the A point inserts cathode power supply, when the B point is negative power supply, the adhesive under diode D3 conducting of the pull-in winding of relay J 3, input 2 pin of relay J 3 and 4 pin conductings are delivered to the output of C point to the positive pole of power supply.The pull-in winding of relay J 1 is ended and not conducting by diode D1.When the B point is negative power supply, the adhesive under diode D4 conducting of the pull-in winding of relay J 4, input 2 pin of relay J 4 and 4 pin conductings are delivered to the output of E point to power cathode, and the pull-in winding of relay J 2 is ended and not conducting by diode D2.No matter how 2 of A, B input electric power polarity changes, the C of output, E two point source polarity are constant all the time.The method of attachment at conversion of nonpolarity input fixed polarity output DC source and IMAGE power supply station keeps stubborn mouthful of joint on the incoming line of former power supply station, remove the storage battery clip of power input line other end, the both positive and negative polarity that the both positive and negative polarity line is inserted the output of this electric power polarity transducer respectively connects on the post, tighten the screws is at last on the both positive and negative polarity pole of two clip 12V storage batterys on the electric power polarity transducer input link.The electric power polarity that (annotate: the clip of incoming line is regardless of positive-negative polarity) can realize supplying with IMAGE power supply station conversion is automatically avoided burning out the power supply station because of the misconnection electric power polarity
Nonpolarity input fixed polarity output DC source converter, it is simple in structure, reliable operation, element is common easily to be purchased, cost of manufacture is low, can be widely used in the power supply station of the IMAGE in the oil seismic exploration, measures that equipment moves frequently in the construction in the open air such as employed high power station, easily cause the misconnection electric power polarity, burn out on the power consumption equipment.Can improve the utilization rate of power consumption equipment, fall the maintenance cost of end equipment.
