Description

Current transformer Technical Field The utility model relates to the technical field of current transformers, in particular to a current transformer. Background The current transformer is an instrument for converting primary side large current into secondary side small current according to an electromagnetic induction principle to measure, and consists of a closed iron core and a winding. Among the prior art, a current transformer as proposed in patent application number "CN201520394322.9", including the transformer body, the transformer body includes the casing, the busbar hole has been seted up at the casing center, the busbar hole has been seted up at the busbar center, the longitudinal section shape of busbar hole is circularly, be provided with two at least rectangle grooves that supply the rectangle busbar to place on the inner wall of busbar hole, the rectangle groove uses the busbar hole to set up for central symmetry as the center, the rectangle groove extends to the front and back both ends face of casing along the axis of busbar hole, first fillet has been seted up to the position that the busbar hole contacted with the casing terminal surface, the second fillet has been seted up to the position that the rectangle groove contacted with the casing terminal surface. However, in the above patent, when the current transformer is used for a long time, the connection end of the bus is easy to drop from the inside of the bus hole, which causes a circuit failure of the current transformer, and the current transformer needs to be checked and maintained by a worker, so that the use of a user is inconvenient. Disclosure of utility model The present utility model is directed to a current transformer for solving the above-mentioned problems. The aim of the utility model can be achieved by the following technical scheme: The utility model provides a current transformer, includes transformer body and fixed subassembly, fixed subassembly includes the standing groove, and the standing groove is seted up in one side of transformer body.
