Description

Technical Field

[0001] The utility model relates to the technical field of assembled shells for mutual inductors, in particular to an assembled shell for mutual inductors. Background Art

[0002] High-voltage cables are widely used in high-voltage power transmission and transformation networks, and most of them are installed by direct burial, tunnel or bridge. In order to fully understand the real-time status of the cable, online detection is usually adopted, that is, online monitoring equipment is installed, such as circulating current monitoring devices, cable induction energy extraction devices, etc., and each detection device is usually equipped with a current transformer. The current transformer is an instrument that converts the large current on the primary side into the small current on the secondary side for measurement based on the principle of electromagnetic induction. The current transformer is composed of a closed iron core and a winding. Its primary side winding has very few turns and is connected in series in the circuit of the current to be measured. In order to facilitate the installation of the current transformer, an open-and-close structure is usually adopted. After the two half-shaped transformer shells are matched and locked, the internal iron core end faces are closely matched with each other, so that the two iron cores form a full circle and form a complete current transformer.

[0003] The assembled housing for a transformer disclosed in the Chinese utility model patent application disclosure CN214753228U has the advantages of detachable connection, convenient assembly, simplified manufacturing process, etc., but the assembled housing for a transformer still has disadvantages: First, the assembled housing for a transformer locks and assembles two parts through a plug-in part and a locking part. In actual use, since the plug-in part is connected by plug-in activities, the plug-in part may fall off during movement at the same angle, and if the locking part is deformed, it may also be impossible to lock, resulting in loose closure between the left and right parts, affecting the work quality; Second, the shell of the assembled housing for a transformer is an upper and lower integrated arrangement. In actual use, the transformer needs to be assembled in the inner shell. This integrated arrangement may not be very convenient during installation and assembly operations, and the use efficiency is not high. Utility Model Content
