The invention provides a transformer lead connecting device, comprising a wire clamp housing, a transformer lead clamping portion arranged on the wire clamp housing, and two temperature indicating units for indicating different temperatures, wherein the wire clamp housing comprises installation holes for installing the temperature indicating units. Each temperature indicating unit comprises a temperature indicating rod, an elastic component and double metal sheets for locking the temperature indicating rod, wherein the temperature indicating rod is movably arranged in one installation hole, the elastic component is arranged in the installation hole, and one end of the elastic component abuts against the temperature indicating rod. Due to arrangement of the temperature indicating units, the wire clamp housing generates heat when transformer leads are not tightly connected with the transformer lead connecting device, so that the double metal sheets deform for heating, and furtherly the temperature indicating rods are sprung out of the installation holes; thus, a work staff can be aware of connection states of the transformer leads and the transformer connecting device and carry out maintenance timely, thereby reducing energy loss and improving reliability of line operation.
Description
technical field [0001] The invention relates to the field of wire installation, in particular to a transformer wire connection device. Background technique [0002] In the field of power engineering, it is often necessary to connect the transformer wires to the power equipment through the connection device when performing outdoor power distribution operations. Due to the complex outdoor working environment, the connecting device should have stable and reliable performance, and should not be affected by temperature and weather conditions, so as to avoid potential safety hazards. [0003] The transformer wire connection device in the prior art includes a wire clamp housing, a clamping block and a locking bolt. The clamping clamp is installed in a groove of the clamp housing through the locking bolt. A line space is formed between the bodies. The transformer wire is arranged in the clamping space, and the transformer wire can be firmly clamped in the transformer wire connecti...
