Batch meter pressure test ground connection combination row includes 10 intermediate terminals of connection High-voltage measuring box secondary line, connects 10 intermediate ends
10 colors of son correspond to identical central conductor, are shorted three short-circuited terminals equipped with five holes for connecting the central conductor
It arranges, is mutually shorted between three short-circuited terminals row by being shorted conducting wire, two short-circuited terminals in outside arrange the company of respectively corresponding
Connect zero curve and ground line.
Preferably, the intermediate terminal is press terminal.
Preferably, the short-circuited terminal row is that press terminal is arranged.
Preferably, the short-circuited terminal row selects the terminal block of PCT-215 terminal model.
Preferably, it is 2.5~4mm that central conductor and short circuit conducting wire, which are all made of core,2, line skin be rubber copper wire.
The utility model has the advantages that directly that the secondary line of High-voltage measuring box and the intermediate terminal of the pressure test ground connection row of combination is corresponding slotting
It connects and ground connection can be completed, it is easy to operate, it is convenient and efficient, greatly reduce operation difficulty；It is high to be grounded accuracy rate, greatly reduces mistake
Accidentally rate, improves equipment safety, personnel safety guarantee；It is convenient for carrying, that is, takes and use, save the separated time time of taking out stitches, improve
Working efficiency.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of High-voltage measuring box pressure test ground connection combination row；
In figure, intermediate terminal 1, short-circuited terminal row 2, central conductor 3, short circuit conducting wire 4, secondary line 5, zero curve 51, A phase 52, B
Phase 53, C phase 54, ground line 6.
Specific embodiment
Further the invention will be further described with reference to the accompanying drawings and examples.
Fig. 1 illustrates a kind of High-voltage measuring box pressure test ground connection combination row, is mainly used for High-voltage measuring box pressure test
When secondary line 5 be grounded, 5 bus of secondary line include 51, three 52 lines of A phase of a zero curve, three 53 lines of B phase, three 54 lines of C phase,
The wiring of each phase, which respectively corresponds, is set as a kind of color, and 52 line of A phase is green in the present embodiment, and 53 line of B phase is blue, C
54 line of phase is red, and zero curve 51 is black.The High-voltage measuring box pressure test ground connection combination row includes connection High-voltage measuring box
10 intermediate terminals 1 of secondary line 5, the intermediate terminal 1 connect 10 identical centres corresponding with color in 5 bus of secondary line
Conducting wire 3,3 other end of central conductor are all connected with short-circuited terminal row 2, and short-circuited terminal row 2 is all provided with that there are five connect for three
The short-circuited terminal row 2 of string holes, in this way, zero curve 51 and 52 line of A phase, which are inserted short-circuited terminal row 2, occupies wherein four wiring
Hole, 53 line of B phase are inserted into three wiring holes of another short-circuited terminal row 2, and 54 line of C phase is inserted into the three of the last one short-circuited terminal row 2
A wiring hole, moreover, being shorted connection, short-circuited terminal where 54 line of C phase further through short circuit conducting wire 4 between three short-circuited terminal rows 2
