The matching apparatus of the utility model features simple structure, convenient installation, raised working efficiency, and fool proof design.
Description
Technical field
The utility model relates to the inverter technology field, is specifically related to the match connecto of a kind of many inverters and three phase network.
Background technology
The inverter that connects electrical network is generally single-phase inverter; When combining inverter is connected with three phase network; The inverter output line is P21, P22, P2N, PE, and wherein P21 and P22 are 120V to the phase voltage of P2N, and electrical network is the electrical network of three-phase five-wire mode (L1, L2, L3, N, PE); The phase line of inverter links to each other with two of electrical network, and zero line links to each other with the electrical network zero line.Three-phase power balance when many inverters are generated electricity by way of merging two or more grid systems must make between the live wire L1L2 on the electrical network, between the L2L3 so, be connected with the inverter of equal number between the L1L3.In order to realize this target, go to judge through the people is installed usually, but when inverter had a lot of platform, installation more complicated and efficient were very low, and easy error; Another kind of way is to do three kinds of inverter output end, and L1L2, L2L3, the L1L3 of corresponding electrical network because lead-out terminal is fixedly connected with inverter, from the angle of conformity of production, produces three kinds of inverters and seem cumbersome respectively.
The utility model content
The utility model provides the match connecto of a kind of many inverters and three phase network to the problems referred to above, and purpose is: easy for installation, increase work efficiency, and be easy to realize connecting of many inverters and electrical network three-phase power balance.
The technical solution of the utility model: the match connecto of a kind of many inverters and three phase network is characterized in that: said match connecto comprises the four-core plug that five core sockets that the five-core cable, the five-core cable that are connected to the electrical network Three-phase five-wire drawn and combining inverter are drawn.
Said five core sockets are circular, and five cores are P11, P12, P13, P1N, PE, and wherein P11, P12, P13 are isometric to the distance in the center of circle, and P11, P12, P13 are 120 ° to the straight line connecting line angle in the center of circle.
Said P1N is in the center of circle, and PE is made up of three circular arcs that with the center of circle are round dot.
Said four-core plug is circular, and four-core is P21, P22, P2N, PE, and wherein P21, P22 are isometric to the distance in the center of circle, and P21, P22 are 120 ° to the angle of the straight line connecting line in the center of circle.
Said P2N is in the center of circle, and PE is made up of three circular arcs that with the center of circle are round dot.
Said five core sockets at the P11 place, there is the fool proof breach at P12 place, P13 place, and the breach of butt joint is with it also arranged on the four-core plug.
The position of said breach has at the P11 place, three kinds at P12 place, P13 place.
The utility model beneficial effect: the utility model is simple in structure, and is easy for installation, can effectively increase work efficiency, and have the advantage of fool proof.
Description of drawings
Accompanying drawing is that the utility model connects sketch map.
Embodiment
Below in conjunction with accompanying drawing and instance the utility model is done further detailed explanation.
As shown in the figure, the match connecto of a kind of many inverters and three phase network comprises the four-core plug that five core sockets that the five-core cable, the five-core cable that are connected to the electrical network Three-phase five-wire drawn and combining inverter are drawn.Said five core sockets are circular; Five cores are P11, P12, P13, P1N, PE, and wherein P11, P12, P13 are isometric to the distance in the center of circle, and P11, P12, P13 are 120 ° to the straight line connecting line angle in the center of circle; P1N is in the center of circle, and PE is made up of three circular arcs that with the center of circle are round dot.Said four-core plug is circular, and four-core is P21, P22, P2N, PE, and wherein P21, P22 are isometric to the distance in the center of circle, and P21, P22 be 120 ° to the angle of the straight line connecting line in the center of circle, and P2N is in the center of circle, and PE is made up of three circular arcs that with the center of circle are round dot.Said five core sockets at the P11 place, there is the fool proof breach at P12 place, P13 place, and the breach of butt joint is with it also arranged on the four-core plug.The position of the breach of five core sockets of grid side and P11, P12, P13 three cores relation has three kinds, and all sockets all are connected with electrical network is consistent, and promptly P11-L1, P12-L2, P13-L3, P1N-N dock respectively.
Realize connecting of many combining inverters and electrical network three-phase power balance, must make the inverter that equal number is arranged on L1L2, L1L3, the L2L3 phase line.Can know that by above description five core sockets have three kinds, socket and plug according to the difference of fool proof gap position, realize that live wire P21, the P22 of inverter is connected with L1L2, L1L3, L2L3 phase line respectively through manually connecting.So, as long as when many combining inverters being installed being incorporated into the power networks, the quantity of these three kinds of sockets is equated, just realized connecting of many combining inverters and electrical network three-phase power balance.
