Description

Anti-off-line current transformer Technical Field The utility model relates to the technical field of current transformers, in particular to an anti-off-line current transformer. Background The current transformer is used as key measuring and protecting equipment in a power system, is widely used in the fields of current monitoring, electric energy metering, relay protection and the like, and has the core functions of converting primary side large current into secondary side small current in proportion through an electromagnetic induction principle, and providing standardized input signals for subsequent equipment. Through retrieving, chinese patent with bulletin number CN222015226U discloses a current transformer, the device drives two connecting plates through the resilience force of four springs and moves back automatically, two sliders of connecting plate one side are fixed respectively at the inner wall of two spouts when removing to make the connecting plate more stable at the in-process that removes from this, but the device outside electric wire is directly connected with binding post, when the outside electric wire receives the pulling force, like the circumstances such as bump the electric wire by mistake when overhauling or installing the current transformer, the electric wire directly pulls binding post this moment, makes electric wire and binding post break away from easily, and then influences current transformer's normal use. Disclosure of utility model In order to overcome the above-mentioned drawbacks of the prior art, the present utility model provides an anti-wire-disconnection current transformer, so as to solve the problems in the prior art. The utility model provides a current transformer capable of preventing wires from falling off, which comprises a current transformer body, wherein one side of the current transformer body is provided with two wiring terminals, one side of the current transformer body is connected with two groups of L-shaped guide rails through bolts, each group is two mirror images, a T-shaped seat is connected between the two L-shaped guide rails in a sliding manner, one side of the upper surface of the T-shaped seat is rotationally connected with a pressing plate, the opposite sides of the T-shaped seat and the pressing plate are respectively provided with a groove I and a groove II, one end of the pressing plate is provided with a clearance groove, one side of the T-shaped seat is provided with a square groove, a rotating rod is rotationally connected between the inner walls of the two sides of the square groove, a threaded rod is fixedly connected to the circumferential outer wall of the rotating rod, and a fixing screw is connected to the threaded rod penetrating through part of the circumferential outer wall of the clearance groove in a threaded manner.
