Abstract
The invention relates to a connecting line dedicated to current transformer tests. The connecting line is characterized in that one end of a positive wire and one end of a negative wire are equipped with a plug, while the other end of the positive wire and the other end of the negative wire are equipped with binding posts equipped with jacks, that a button switch is disposed on the positive wire, that the plug can be inserted into a charging jack of an electric torch, and that the binding posts equipped with jacks can be connected with wires on the primary side of a current transformer. When the connecting line is used to perform a current transformer polarity test, the end equipped with plug is inserted into the charging jack of the electric torch; then the other ends of the connecting line provided with the binding posts are connected with the wires connected with the primary side of the current transformer. Current can be added to the current transformer by pressing the button switch. In addition, the electric torch can be simultaneously used to carry out illumination, thereby saving manpower and increasing work efficiency.
Description
?
Technical field
The present invention relates to a kind of electrical apparatus test aid, particularly a kind of Special-purpose connecting line for current transformer polarity test.
Background technology
When carrying out current transformer polarity test, conventionally need to use the battery of a 1.5V, staff receives an end of battery a terminal of tested current transformer, the other end is clicked another terminal of current transformer, the ammeter pointer connecting at the secondary side of current transformer rotates, and judges that thus whether the polarity of current transformer is correct.If current transformer is arranged on light, not so good place just needs flashlight lighting, and needs a people to take flashlight lighting, and another people takes battery to click, and sometimes accurately also necessary by two battery serial connections in order to test, operation is extremely inconvenient.
Summary of the invention
The object of the invention is to overcome the deficiencies in the prior art, a kind of current transformer test Special-purpose connecting line is provided.
The object of the present invention is achieved like this: a kind of current transformer test Special-purpose connecting line, it is characterized in that being provided with plug in one end of one section of both positive and negative polarity wire, and the other end is provided with the connection terminal with jack, on the positive pole of wire, is provided with pushbutton switch.
Described plug, for inserting the plug of electric torch charging jack, can once hold wire to be connected with current transformer with the connection terminal of jack.
The invention has the advantages that: use the present invention to carry out current transformer polarity test, as long as the one end with plug is inserted in the charging socket of electric torch, and then the other end with splicing ear is connected to current transformer and is once held on the wire being connected, pressing pushbutton switch can be added to electric current on current transformer, and can with electric torch, throw light on simultaneously, save manpower and improved again work efficiency.
Accompanying drawing explanation
Fig. 1 is circuit theory diagrams of the present invention;
Fig. 2 is the circuit theory diagrams of the present invention while using.
Embodiment
Below in conjunction with accompanying drawing, the invention will be further described:
As shown in Figure 1: the present invention is one section of both positive and negative polarity wire 1, its one end is provided with the plug 2 that can insert electric torch charging jack, and the other end is provided with the connection terminal 3 with jack, is provided with pushbutton switch 4 on the positive pole of wire.As Fig. 2, in use, plug is inserted in the charging hole of electric torch 5, and the connection terminal with jack is connected to current transformer 6 once holds on 7 connected wires, press pushbutton switch, just the electric current of electric torch output can be added on current transformer, reometer 9 pointers that now can connect by Current Transformer Secondary end 8 rotate and judge that whether its polarity is correct, meanwhile, can also throw light on electric torch.
Claims (2)
