Problems solved by technology

[0002] The distribution transformer is a device that uses the principle of electromagnetic induction to change the AC voltage. The main components are the primary coil, the secondary coil and the iron core. The coil resistance inside the distribution transformer is related to the energy efficiency measurement of the transformer output. It is necessary to use testing equipment to Whether there is a fault in the resistance detection of the coil to ensure the energy efficiency of the distribution transformer output, but because in the process of detecting the coil inside the distribution transformer, it is necessary to use the resistance detection head to contact the coil, the coil diameter inside the different transformer Different, and the coil is installed inside the transformer. During the detection of the coil by the detection head, the contact strength between the detection head and the coil is not good, and it is easy to fall off from the coil, resulting in certain errors in the detected data, reducing the Accuracy of Energy Efficiency Metering Detection

Abstract

The invention discloses distribution transformer energy efficiency metering detection equipment. Thedistribution transformer energy efficiency metering detection equipment structurally comprises a placing table, an electric control box, a supporting frame and a direction adjusting mechanism, the electric control box is installed on the upper end face of the placing table, the rear side end of the placing table is welded to the lower end of the supporting frame, and a resistance testing head is adjusted to be in the direction abutting against the outer side of a coil. The spring rod is used for elastic supporting, a wire is synchronously pulled, the torsion spring drives a winding roll to rotate, and the length of the wire is automatically adjusted, so that normal electrification of the resistance testing head is ensured, and the resistance testing head is prevented from falling off from the coil; in the descending process of a linkage disc, the middle end of the outer side of the transformer abuts against an extrusion sliding block, the two ends of the outer side of the attaching piece draw close to the inner side, at the moment, the extrusion ball generates elastic force, the abutting capacity of the abutting piece and the outer side surface of the transformer is improved, and displacement of a detection head at the lower end of the linkage disc in the detection process is avoided, therefore, the accuracy of detecting the resistance of the coil by the detection head is improved.

Description

Technical field [0001] The present invention relates to the field of distribution transformers, and more particularly, and more particularly to a distribution transformer energy efficient measurement device. Background technique [0002] The power distribution transformer is a device that uses electromagnetic induction to change the AC voltage, the main component is the primary coil, secondary coil, and core, the coil resistance inside the distribution transformer is related to the energy efficiency meter of the transformer output, and needs to be used to detect the detection device pair. The coil performs resistance detection whether there is a fault to ensure the energy efficiency of the distribution transformer output, but since the coil inside the power distribution transformer is detected, the resistance detection head is in contact with the coil, the coil diameter inside the different transformer Different, and the coil is mounted inside the transformer, and the detection h...
