Embodiment 1

[0028] A transformer that is convenient for connecting external cables, including a base, on which several iron cores are installed, coils are set on the iron cores, an insulating tube is placed on the coils, a connecting frame is installed on the base, an insulating plate is installed on the connecting frame, and an insulating An insulating bellows is also installed above the barrel, and the adjacent insulating barrels are sealed and fixed by insulating angle steel. The wiring ports of the coils are all close to the side of the insulating bellows and fixed on the insulating plate.

[0029] Through this setting, the wiring port of the coil is set on the upper part, and there is no need to wrap the cable downward when connecting the external cable, which not only facilitates the connection construction, but also saves the length of the cable and reduces the consumption of the cable, which is more economical and practical. The problem of inconvenient external connection cables of...

Abstract

The invention discloses a transformer convenient for external connection of a cable, belongs to the technical field of transformers, aims to provide a transformer convenient for external connection ofa cable, and solves the problem that an existing dry-type transformer is inconvenient for external connection of a cable. The transformer comprises a base, wherein a plurality of iron cores are installed on the base, the iron cores are sleeved with coils, the coils are sleeved with insulating cylinders, a connecting frame is installed on the base, an insulating plate is installed on the connecting frame, an insulating air air is further installed above the insulating cylinders, the adjacent insulating cylinders are sealed and fixed through insulating angle steel, and the wiring ports of the coils are close to one side of the insulating air box and are fixed on the insulating plate. The transformer is suitable for being externally connected with a cable conveniently.

Description

technical field [0001] The invention belongs to the technical field of transformers, and in particular relates to a transformer that is convenient for connecting external cables. Background technique [0002] As known, the current dry-type rectifier transformer is mainly used in the excitation system of the generator, the electrochemical industry, the direct current grid of the electric locomotive on the mine or the railway, and the like. With the rapid development of modern power electronics technology and microelectronics technology, frequency conversion speed control devices are becoming more and more mature, and their application fields and scope are becoming more and more extensive, which makes efficient and reasonable use of energy, especially electric energy. possible. Frequency conversion speed regulation has also been listed as one of the three resource-saving and comprehensive utilization technological transformation demonstrations implemented by key national orga...
