Abstract

The invention relates to the technical field of power transformers, and discloses a power transformer for preventing a cable from loosening. The power transformer includes a base, the top of the baseis fixedly connected with a protective shell. A heat dissipation groove is formed in one side of the protective shell, a waterproof pad is fixedly connected to the inner wall of the protective shell,a first fixing block is fixedly connected to the inner side wall of the waterproof pad, a reset spring is fixedly connected to one side of the first fixing block, and a second fixing block is fixedlyconnected to the outer wall of the reset spring. According to the power transformer for preventing a cable from loosening, the purpose of good fixing effect of the power transformer cable is achieved;therefore, the problem of poor cable fixing effect of a common power transformer is solved; dangerous situations are further reduced, meanwhile, property losses of people are reduced, the working efficiency of the power transformer is indirectly improved, people can use the power transformer more easily, the use requirements of people are further met, and convenience is brought to work of people.

Description

technical field [0001] The invention relates to the technical field of power transformers, in particular to a power transformer for preventing cable loosening. Background technique [0002] Transformer, also known as instrument transformer, is a general term for current transformer and voltage transformer. It can change high voltage into low voltage and large current into small current. It is used for measurement or protection system. Its function is mainly to convert high The voltage or large current is converted into standard low voltage or standard small current in proportion to realize the standardization and miniaturization of measuring instruments, protection equipment and automatic control equipment. safety. [0003] However, the protection effect of the general power transformers on the market is not very good. During the long-term use of the power transformers, the cables are easy to fall off from the joints, which leads to a series of dangers or property losses, a...
