Fig. 1, Figure 2 shows that the terminal of two kinds of three-phase electric energy meters distributes, as we know from the figure, the auxiliary terminal quantity and the position of two kinds of ammeters are identical, and other terminal position is neither identical.According to the technology that new ammeter calibration equipment is adopted, two kinds of ammeters all need to connect current terminal and ground terminal (zero terminal), and voltage terminal and auxiliary current terminal have only mutual inductor access type ammeter just to have, and directly the access type ammeter does not then have; The current terminal upper-lower position of two kinds of ammeters is identical, and is different about having only, thus the current terminal on the meter adapting-seat only need can about adjust and get final product; Two kinds of ground terminals (zero terminal) that ammeter all has two internal electrics to be communicated with, only need connect one of them just during test, analyze as can be known, the ground terminal upper-lower position difference of two kinds of ammeters, but the position, the left and right sides, ground terminal hole, the left side of the ground terminal hole, the right of mutual inductor access type and direct access type is basic identical, therefore, the ground terminal probe of meter adapting-seat can only be established one, be used for docking this essentially identical ammeter ground terminal hole, position, two left and right sides, like this, the ground terminal of meter adapting-seat only needs above-below direction adjustment position to get final product.
Fig. 4 is the vertical view of the utility model meter adapting-seat, as existing meter adapting-seat, this meter adapting-seat comprises mounting base 1, current terminal assembly 2, ground terminal assemblies 3, voltage terminal assembly 4, the axis of guide 5, wherein mounting base 1 is fixedly connected with the axis of guide 5, current terminal assembly 2 comprises three current terminal groups, and these three current terminal groups are cascaded by the axis of guide 5.According to the utility model, this meter adapting-seat also comprises horizontal pushing mechanism 6 and current terminal group back-moving spring 7 that is associated with each current terminal group and current terminal group stroke limit spare 8 (see figure 5)s, each current terminal group can horizontally slip at the effect lower edge axis of guide 5 of corresponding electric current terminal group back-moving spring 7 and horizontal pushing mechanism 6, and its sliding stroke is subjected to the qualification of current terminal group stroke limit spare 8.
Three current terminal groups of current terminal assembly 2 include two current terminals 15, and described current terminal can horizontally slip and realizes the purpose that position, the left and right sides is adjusted with corresponding electric current terminal group.As shown in Figure 6, current terminal 15 mainly is made of holddown spring 16, contact 17, binding post 18 and insulation cover for seat 19, and the suffered pressure of terminal was provided by holddown spring 16 when this structure assurance meter adapting-seat docked with electric energy meter.
Adopt hinge-coupled between preferred ground terminal assemblies 3 and the mounting base 1, as shown in Figure 7, ground terminal assemblies 3 can be rotated around jointed shaft 21 under the effect of horizontal pushing mechanism jacking block 9 and back-moving spring 12, and ground terminal probe 20 is being realized upper-lower position adjustment in hinge 21 rotating process with ground terminal assemblies 3.
Referring to Fig. 3, Fig. 4, voltage terminal assembly 4 of the present utility model is connected on the mounting base 1 of meter adapting-seat by guide rail 14, and the direction that can limit at this guide rail 14 be on the fore-and-aft direction relatively mounting base 1 slide, but about and above-below direction is neither can move.Be equipped with on the installing plate 22 of this voltage terminal assembly 4 and only be used for mutual inductor access type ammeter just with the voltage terminal probe 23 and the auxiliary current terminal probe 24 that obtain.
Referring to Fig. 8, the cylinder 10 that horizontal pushing mechanism 6 comprises jacking block 9 and promotes this jacking block, cylinder 10 is fixedly connected on mounting base 1.Jacking block 9 is provided with an inclined-plane 11 and matches with ground terminal assemblies 3 to move on the promotion ground terminal.When cylinder 10 stretches out, jacking block 9 moves to left with cylinder rod, and until pickup current terminal assemblies 2 and push it against the leftmost side, the inclined-plane 11 on the jacking block 9 then acts on mutually with ground terminal assemblies 3, ground terminal is up pushed away, until adjusting to and the corresponding position of mutual inductor access type ammeter.
The working method of the meter adapting-seat that is used for the three-phase electric energy meter calibration equipment of the present utility model is as follows:
Meter adapting-seat of the present utility model is mounted on the electric energy meter automatic calibration equipment in order to finish the terminal fast-wiring of three-phase electric energy meter, the current terminal voltage terminal of meter adapting-seat and other auxiliary terminal etc. are by electric wire and testing apparatus electric connection, when calibration equipment need dock with electric energy meter, meter adapting-seat whole reach under the cylinder of calibration equipment promotes, meter adapting-seat current terminal contacts and each terminal of each probe and electric energy meter contacted before this, the calibration equipment cylinder continues to promote the meter adapting-seat reach, the current terminal holddown spring of meter adapting-seat tightly is pressed in current terminal contacts on the electric energy meter electric current terminal, and other probe on the meter adapting-seat also can tightly be pressed on other terminal of electric energy meter, thereby realizes the electric connection between testing apparatus and energy meter terminal.
The handoff procedure of meter adapting-seat between two kinds of ammeter states is such:
When needs dock with mutual inductor access type ammeter, cylinder 10 actions of horizontal pushing mechanism 6, driving jacking block 9 moves to left, jacking block 9 promotes current terminal assembly 2 and is moved to the left, up to current terminal being shifted onto and mutual inductor inserts the corresponding position of ammeter, and in this process, 11 on the inclined-plane on the jacking block 9 acts on mutually with ground terminal assemblies 3, ground terminal is upwards pushed away, up to ground terminal and the corresponding position of mutual inductor access type ammeter.At this moment, current terminal and ground terminal all switch to the state that mutual inductor inserts the ammeter requirement.Then, the execution cylinder 13 of voltage terminal assembly 4 stretches out, and promotes voltage terminal assembly 4 and moves forward, up to the working position that voltage terminal probe 23 and auxiliary current terminal probe 24 move, cylinder 13 no longer moves forward, and voltage terminal and auxiliary current terminal completion status are switched.
When needs dock with direct access type ammeter, at first be execution cylinder 13 withdrawals of voltage terminal assembly 4, drive voltage terminal assembly 4 moves backward, voltage terminal probe 23 on it and auxiliary current terminal probe withdraw from from meter adapting-seat current terminal assembly fully, so far, voltage terminal and auxiliary current terminal completion status are switched, and the two is on the shelf during meter adapting-seat work; Then, execution cylinder 10 withdrawals of horizontal pushing mechanism 6, drive jacking block 9 and move to right, three current terminal groups of ground terminal assemblies 3 and current terminal assembly 2 move down to the right with mutually respectively under the effect of back-moving spring separately, until moving to and directly inserting the position that ammeter adapts.At this moment, all terminal completion statuses are switched.
