Relay terminal 15a, 15b, 15c of closing relay 14 connect.
Similarly, primary side terminal 22a, 22b, 22c utilize conductor plate 13a, 13b, 13c in coulant meter main body 10, pass through
Logical current transformer 11a, 11b, the inside of 11 and be connected with relay terminal 16a, 16b, 16c.
Primary side terminal 21d connects N phase, therefore in the inside of arrangements of terminal 20 by short-circuiting bar 17 with primary side terminal
22d connects.
Arrangements of terminal 20 is integrally provided in the way of constituting the bottom of coulant meter main body 10.
Arrangements of terminal 20 has terminal board 23, this terminal board 23 and primary side terminal 21a, 21b, 21c, 21d, secondary side
The quantity of sub-22a, 22b, 22c, 22d is corresponding, at one end has the electric wire insertion holes 24 for inserting electric wire, inserts with electric wire
Hole 24 relatively has the top for being inserted by metallic plate 29 and lower fixing hole 25,26 at the other end.
Additionally, terminal board 23 is formed as the longest by insulant such as synthetic resin, it is provided with partition wall so that inciting somebody to action
Separate between the primary side terminal of each phase and primary side terminal.
In terminal board 23, the terminal metal piece 27 with rectangular cross section of hollow can along with electric wire insertion holes 24 with
And top and the orthogonal above-below direction of lower fixing hole 25,26 move ground, house and be maintained at electric wire insertion holes 24 and top
And between lower fixing hole 25,26,2 fixing screws 28 are installed on the top of terminal metal piece 27.
These fixing screws 28 enter to the inside of the hollow of terminal metal piece 27 by being screwed into, and are gone out then by spiral shell
Move back.
Metallic plate 29 is inserted into top fixing hole 25 or lower fixing hole 26 as hereinafter described, is fixed on terminal board 23.
Metallic plate 29 for example is by top fixing hole 25 or the pressure of lower fixing hole 26 to the fixing of terminal board 23
Enter, not shown screw and carry out.
Being respectively mounted conductor plate 12a～12b, 13a～13c in the front end of metallic plate 29, both of which utilizes conductor plate to fix
Screw 30 and be fixed.
Conductor plate 13a, 13b, 13c are fixed on opening and closing relay 14 through the inside of current transformer 11a, 11b, 11c.
The metallic plate 29 corresponding with primary side terminal 21d and primary side terminal 22d is not connected with opening and closing relay 14, profit
Short circuit is realized with short-circuiting bar 17.
As shown in Figure 2 and Figure 3, top and lower fixing hole 25,26 with terminal metal piece 27 to move up and down direction relative
The mode answered, separates the interval of regulation and is formed at terminal board 23, is provided with the primary side terminal with each phase and primary side terminal
The corresponding quantity of quantity.
Here, if as shown in Figure 4 metallic plate 29 to be inserted into the lower fixing hole 26 of terminal board 23, then as Fig. 5,
Shown in Fig. 6, terminal metal piece 27 is clipped lower surface by bottom surface and the metallic plate 29 of terminal board 23 and fixes.
That is, if electric wire 18 to be inserted into the electric wire insertion holes 24 of arrangements of terminal 20, fixing screw 28 is screwed into and under
Fall, then electric wire 18 is clipped by the upper surface of metallic plate 29 and the bottom of fixing screw 28 and fixes.
I.e., it is achieved the electric wire fixing means identical with existing screw fastening means.
In this case, the conductor plate 13b being connected with metallic plate 29 is provided with as shown in Figure 6 has position at above-below direction
The crank moved, conductor plate 13b with the position of bottom surface distance L of coulant meter main body 10 by after through for current transformer 11b,
Displacement downwards, utilizes fixing screw 30 and the metallic plate 29 being inserted into lower fixing hole 26 is fixed.
According to present embodiment, by each of arrangements of terminal 20 is implemented same electric wire fixing means mutually, so that using
The coulant meter of the present invention can be corresponding to the electric wire fixing means of screw fastening means.
On the other hand, if as shown in Figure 7 metallic plate 29 to be inserted into the top fixing hole 25 of terminal board 23, then such as figure
8, shown in Fig. 9, terminal metal piece 27 is the most movable in the range of inner face does not contacts with metallic plate 29.
If electric wire 18 to be inserted into the electric wire insertion holes 24 of terminal board 23, it is screwed into fixing screw 28, then terminal metal
Part 27 is in vertically movable state, after therefore contacting with metallic plate 29 by being screwed into fixing screw 28, with fixing
By the amount of being screwed into of screw 28 matchingly, terminal metal piece 27 rises.
Therefore, and electric wire 18 is consolidated by the bottom surface clamping of the lower surface of metallic plate 29 and terminal metal piece 27 as illustrated in fig. 8
Fixed.
Therefore, in this case, it is achieved the electric wire fixing means identical with existing spinning mode.
In this case, as it is shown in figure 9, make that conductor plate 13b's is up and down the most contrary with the situation of Fig. 6, i.e. conductor plate 13b exists
With the position of bottom surface distance L of coulant meter main body 10 by after through for current transformer 11b, displacement upward, utilize fixing
It is fixed with screw 30 and the metallic plate 29 being inserted into top fixing hole 25.
Thus, which side in top fixing hole 25 or lower fixing hole 26 no matter metallic plate 29 be inserted into, and utilizes song
Handle, conductor plate 13b all can with the position of bottom surface fixed distance L of coulant meter main body 10 by through for current transformer 11b.
Being clear that from the explanation employing Fig. 6, Fig. 9, the displacement of the crank of conductor plate 13b is according to top and bottom
The relation between distance and distance L between fixing hole 25,26 and determine.
According to present embodiment, by each of arrangements of terminal 20 is implemented above-mentioned electric wire fixing means mutually such that it is able to
Corresponding to screw fastening means or spinning mode.
Further, since respectively through to current transformer 11a, 11b, 11c conductor plate 13a, 13b, 13c are being provided with and terminal
The top of device 20 and the crank of the interval displacement the most along the vertical direction of lower fixing hole 25,26, the most no matter by gold
Belong to plate 29 be inserted in the top fixing hole 25 of terminal board 23, lower fixing hole 26 which side, conductor plate 13a, 13b, 13c's
Position does not changes relative to current transformer 11a, 11b, 11c, therefore, it is possible to improve the current measurement precision of current transformer.
Additionally, each embodiment freely can be combined in the range of its invention by the present invention, or to each enforcement
Mode suitably deforms, omits.
