Embodiment
Below in conjunction with accompanying drawing, the utility model is specifically described, as depicted in figs. 1 and 2, a kind of current transformer that the utility model provides, comprise instrument transformer body 1, described instrument transformer body 1 is provided with connecting groove 2, two terminations 3 are provided with in described connecting groove 2, described connecting groove 2 is provided with cover plate 7 in hinged mode, the lower wall of described connecting groove 2 is provided with the slot to make way 4 stretched out from the front of instrument transformer for electric wire, wherein, the lower wall of connecting groove is the lower wall shown in Fig. 1, that is be the right side wall in Fig. 2, by this structure, the production difficulty of current transformer can be simplified, electric wire is allowed to stretch out from the front of current transformer, make to have in operation sufficient space and easily observe, effectively can reduce the difficulty of wiring, be beneficial to repair and maintenance, wherein, the front of current transformer refers to the side being provided with connecting groove, top namely shown in Fig. 2.
In the present embodiment, as shown in Figure 3, described termination 3 comprises binding post 33, described binding post 33 is provided with columniform wiring hole 30, tension disc 31 is provided with in described wiring hole 30, described tension disc 31 is fixedly connected with by spring 32 with the sidewall of wiring hole 30, described tension disc 31 is driven by the actuator 34 stretched into from binding post 33 outer radial and is pressed to electric wire, that is to say that tension disc 31 can move upward in the footpath of wiring hole under the driving of actuator, actuator 34 adopts screw, easy to use, without the need to other locking mechanisms, when electric wire is inserted in wiring hole, turn screw, tension disc is made to press to electric wire, electric wire fully contacts with tension disc and binding post, and have screw to lock, make the conductivity after wiring good, reliability is high, when needs take out electric wire, only screw need be unclamped, tension disc automatically resets under the action of the spring, electric wire is facilitated to take out, certainly, tension disc and binding post all adopt conductive material, pass through said structure, the problem that after effectively can avoiding needing to carry out shape transformation to the core of electric wire in traditional mode of connection, wiring difficulty increases, and can avoid causing damage to the core of electric wire in traditional approach and stability being reduced.
In the present embodiment, the axis collinear of the wiring hole 30 of two binding posts 33, the lateral wall of described binding post 33 is provided with U-shaped conducting strip 5, described U-shaped conducting strip 5 can horizontally slip, as shown in Figure 1, left and right is the left and right shown in Fig. 1, wherein, U-shaped conducting strip is positioned by screw and leads, by this structure, when needing current transformer to carry out short circuit, the U-shaped conducting strip being arranged on right side binding post is only needed to slide from right to left, the screw of left side binding post is embedded in the U-shaped mouth of conducting strip, and tightening screw; During without the need to short circuit, U-shaped conducting strip is refitted in position shown in Fig. 1, can reduces difficulty during current transformer short circuit widely, without the need to extra wiring or change the existing mode of connection, easy to operate, wiring is reliable and stable.
