The invention discloses a current transformer installation and correction mechanism for data acquisition. The current transformer installation and correction mechanism comprises a stand column, a vertical support and a single support, wherein the outer wall of the stand column is provided with an opening which is buckled on the circuit of an installment point from top to bottom, two grooves are formed in the outer wall of the stand column in the circumferential direction, and the two grooves are connected with the vertical support and the single support respectively; the vertical support adopts two support fixing pieces, one ends of the two support fixing pieces are connected with the grooves of the stand column through an opening clamping sleeve, the other ends of the two support fixing pieces are connected with an current transformer through a square opening fixing sleeve, a threaded structure is arranged in the vertical support, and the length of a screw rod can be adjusted according to the size of the current transformer. The function of the single support is similar to that of the vertical support. According to the current transformer installation and correction mechanism, thecurrent transformer is fixed through the triangular structure formed by the stand column, the vertical support and the single support, the length of the two supports can be adjusted through an adjusting rod, the current transformer installation and correction mechanism is suitable for current transformers of different sizes, the fixing of the current transformer is realized, the vibration of thecurrent transformer is effectively prevented, and the accuracy of the collected data and the circuit safety are ensured.
