Abstract
The utility model relates to a test device of a mutual inductor of multiple models. The test device comprises a test device worktable, a connecting terminal connected with the output terminal of a mutual inductor coil measured is connected with a display terminal and is fixed and connected on the worktable surface, and the test device also comprises a copper bar bridge, a copper bar padding block, a fixing seat and a fixing bolt; copper bars at the two output end parts of a short end part and a long end part of a direct-connected type current rising transformer are penetrated through the worktable surface, and the copper bar padding block is positioned on the short copper bar end part; a fixed-end column of the fixing seat is respectively arranged at the two output end sides of the current rising transformer, both ends of the copper bar bridge are connected with the fixed-end column with the fixing bolt, and the copper bar bridge is pressed on the upper end surface of the copper bar padding blocks added on the end part of the long copper bar output end and on the output end part of the short copper bar. Because the utility model adopts the direct-connected type current rising transformer, the copper bar bridge can be directly connected with the output end of the transformer, the output current is stable, and the test efficiency is high. The size of the copper bar bridge is determined according to the model of the mutual inductor, the test device performs testing to a plurality of mutual inductors with the same model at the same time, and the testing accuracy is also ensured.
Description
Affiliated technical field
The utility model belongs to a kind of mutual inductor test unit, particularly relates to one kind of multiple model mutual inductor test units.
Background technology
Present known mutual inductor test unit is at work in the stationary fixture device that solves fixing mutual inductor technical matters and adopt, mostly be with tested mutual inductor through on the transportable copper bar that is flexible coupling, and then the copper bar that will be flexible coupling is connected to constant current source and tests.Just can not carry out effectively fixingly like this for mutual inductor, especially just may produce than mistake for those hollow mutual inductor test findings that testing position is had relatively high expectations.If at this moment require the mutual inductor of a plurality of same model is tested simultaneously, then adopt the original copper bar that is flexible coupling not only to connect inconvenience, and testing result is brought bigger influence.
Summary of the invention
The utility model provides a kind of multiple model mutual inductor test unit with reliable and stable grip device for solving the technical matters that exists in the known technology.
The technical scheme that the utility model is taked for the technical matters that exists in the solution known technology is: it includes the connection terminal of test unit worktable, rising current transformer, the tested mutual inductor coil output terminal of connection, this connection terminal is fixed on the described work top and with display terminal and links to each other, and it also includes copper bar bridge, copper bar cushion block, holder and set bolt; Described rising current transformer is a direct connecting type rising current transformer, two output terminals of direct connecting type rising current transformer are two copper bars that one is long and the other is short, described worktable is passed in the end of these two copper bars, described copper bar cushion block is positioned on the copper bar end of the described weak point of direct connecting type rising current transformer, and this moment, short copper bar added that at the height more than the described work top height of described copper bar cushion block equals the height of copper bar end more than described work top of the described length of direct connecting type rising current transformer output terminal; Two fixed-end columns are respectively by two output terminals of direct connecting type rising current transformer, the two ends of described copper bar bridge link to each other with two fixed-end columns of described holder by set bolt, and simultaneously described copper bar bridge are pressed in tightly on the upper surface of the described copper bar cushion block that is added with on the end of the long copper bar output terminal of rising current transformer and the short copper bar output terminal of rising current transformer.
The utility model can also adopt following technical measures:
The connection terminal of the tested mutual inductor coil output terminal of described connection is that 1-20 is right.
Advantage and the good effect that the utlity model has are: owing to adopted direct connecting type rising current transformer, make the copper bar bridge directly to export copper bar with transformer and be connected, thereby outputting current steadily, detection efficiency are higher.The size of copper bar bridge can be decided according to the mutual inductor model, and can make the mutual inductor of a plurality of same model simultaneously; Position relative fixed when detecting owing to each mutual inductor in addition, its accuracy of detection also is guaranteed.Can only unclamp the set bolt of copper bar cushion block one side when the use of copper bar cushion block makes test, take off the copper bar cushion block and can carry out the replacing of mutual inductor easily.

Embodiment
For further understanding summary of the invention of the present utility model, characteristics and effect, exemplifies now and following the present invention is used for the embodiment of intelligent electrical apparatus release testing table, and conjunction with figs. is described in detail as follows:
As shown in Figure 1, two of direct connecting type rising current transformer output terminal copper bar A table top of passing test unit worktable E stretches out on the table top of worktable E.Two output terminal copper bar A of direct connecting type rising current transformer are that one is long and the other is short.On the table top of test bench E, be fixed with 4 couples of connection terminal F that link to each other with the detection voltage table.Copper bar cushion block B is placed on the end face of the short end of direct-connected transformer output terminal copper bar A, just in time the height with the long upper surface of holding of direct-connected transformer output copper bar A is identical for the height of copper bar cushion block B upper surface at this moment, copper bar bridge C two ends are placed on copper bar cushion block B and the upper surface of direct-connected transformer output copper bar A than a long end, and link to each other with two fixed-end columns of holder D with set bolt D '.Copper bar bridge C tightly fastens by copper bar cushion block B and direct-connected transformer two ends output copper bar A and links together like this.
During test, only need unclamp the set bolt D ' of copper bar cushion block B one side, taking off copper bar cushion block B can be set in mutual inductor to be detected on the copper bar bridge C, having worn mutual inductor loads onto copper bar cushion block B the set bolt D at copper bar bridge C two ends is tightened, two ends and connection terminal F with mutual inductor coil connects again, can test.
The size of direct connecting type rising current transformer output copper bar A and copper bar bridge C can be decided according to the physical dimension and the test number of the detected mutual inductor of concrete test usefulness.And connection terminal also can be more than 20 pairs.
