Detailed Description
Coil material detection device embodiment:
the coil material in this embodiment is a current transformer 1, and the current transformer 1 has a coil and four pins, two of the pins are pins 11 and 12 of the coil, and the other two pins are vacant, and the vacant pins are not shown in the figure.
Detection device includes case shell 2, dials shelves switch 3, detection terminal 4 and four material connection module 5, and four material connection module 5 and dial the equal fixed mounting of shelves switch 3 on case shell 2, detection terminal 4 draws forth from case shell 2.
The material connection module 5 has a first plug hole 51, a second plug hole 52, a third plug hole 53 and a fourth plug hole 54, wherein the third plug hole 53 and the fourth plug hole 54 are empty, and a resistor 6a is electrically connected between the first plug hole 51 and the second plug hole 52 of the same material connection module 5.
The detecting terminal 4 has a first detecting end 41 and a second detecting end 42, each first inserting hole 51 is electrically connected to the first inserting hole 51, each second inserting hole 52 is electrically connected to a different gear interface of the shift switch 3, and the second detecting end is electrically connected to the main interface of the shift switch 3, so that the second detecting end can be electrically connected to the different second inserting holes 52 in a switchable manner.
When the detection device is used for detecting the electrical property of the current transformers 1, in the first step, each current transformer 1 is inserted into each material connection module 5, one of two pins serving as coil pins 11 and 12 is inserted into the first insertion hole 51, and the other pin is inserted into the second insertion hole 52; secondly, an external lead 7 sequentially penetrates through the ring space of each current transformer 1 and is used for electrifying the lead 7; thirdly, electrically connecting the first detection end 41 and the second detection end 42 to two probes of the universal meter in a one-to-one correspondence manner; and fourthly, shifting the gear shifting switch 3 to sequentially detect the electrical property of each current transformer 1.
Specifically, the first detection end 41 and the second detection end 42 are respectively connected with a clamping member (not shown in the figure); two holders all are used for the probe of centre gripping universal meter (not shown in the figure), detect induced voltage through the universal meter, then realize the detection to current transformer 1 electric property.
Alternatively, in other embodiments of the invention, the cabinet 2 may be eliminated, such that the material connection modules 5 are provided separately; the purpose of conveniently and rapidly detecting the electrical property of the current transformer 1 can be achieved; of course, the scheme of arranging the case shell 2 in the embodiment is preferably adopted, and at least part of the wires of the resistor and the detection device are packaged in the case shell 2, so that the safety performance of the detection device is improved, the position stability of each material connection module 5 is also facilitated, and the convenience in operation of the plugging process of the current transformer 1 and the material connection module 5 is further facilitated.
Alternatively, in other embodiments of the present invention, the material connection module 5 may also omit the third insertion hole 53 and the fourth insertion hole 54, which also satisfies the function of conductive insertion of the current transformer 1, and of course, the material connection module 5 of this embodiment is preferably adopted, so that the four pins of the current transformer 1 can be inserted into the four insertion holes one by one, which is favorable for stable and reliable insertion and matching between the current transformer 1 and the material connection module 5.
Alternatively, in other embodiments of the present invention, the resistor 6a may be eliminated, and the resistor 6b is electrically connected between the first detecting terminal 41 and the second detecting terminal 42, which also achieves the object of the present invention, and is beneficial to reducing the number of resistors and simplifying the structure of the detecting device.
Preferably, in the same material connection module 5, the first insertion hole 51 is electrically connected with the third insertion hole 53, and the second insertion hole 52 is electrically connected with the fourth insertion hole 54; and since four pins are generally located at the four vertices of the same rectangle, for example: two pins electrically connected with the coil are separated by a first distance, two empty pins are also separated by the first distance, but the pins 11 and 12 of the coil are separated by a second distance, namely the distance between the first plugging hole 51 and the second plugging hole 52 is the first distance, the distance between the third plugging hole 53 and the fourth plugging hole 54 is the first distance, but the distance between the first plugging hole 51 and the third plugging hole 53 is the second distance, the distance between the second plugging hole 52 and the fourth plugging hole 54 is the second distance, and the second distance is not equal to the first distance; therefore, the two pins 11 and 12 of the coil cannot be respectively inserted into the first inserting hole 51 and the third inserting hole 53, and also cannot be simultaneously inserted into the second inserting hole 52 and the fourth inserting hole 54, so that when the current transformer 1 is inserted, the corresponding relation between each pin of the current transformer 1 and each inserting hole of the material connecting module 5 does not need to be considered, as long as the current transformer 5 and the material connecting module 5 can realize the inserting matching, the detection on the electrical property of the current transformer 5 can be realized, the process of identifying the pins 11 and 12 of the coil and the inserting holes is favorably reduced, the detection process is favorably simplified, the time required for detecting the current transformer 1 is shortened, and the detection efficiency is improved.
