Abstract

The invention provides a contact arm of a voltage transformer handcart, which is characterized in that the contact arm comprises a contact arm base, an insulating contact arm body, a fuse and a contact arm head; wherein the fuse is arrange din the insulating contact arm body; and the contact arm base, the fuse and the contact arm head are successively conducted. According to the contact arm of the voltage transformer handcart according to the invention, the fuse is mounted in the insulating contact arm body, thereby saving a manufacture space, and enabling direct mounting in the voltage transformer cart without restriction by the product space. Simultaneously the contact arm of the voltage transformer handcart performs a function of protecting the voltage transformer.

Description

technical field [0001] The present invention relates to a mechanical device, in particular to a contact arm of a voltage transformer handcart, preferably a contact arm of a 10kV high-voltage power distribution cabinet upper and lower voltage transformer handcart. Background technique [0002] At present, the power distribution cabinet scheme is constantly updated and improved, and the capacity of the voltage transformer in the power distribution system is continuously increasing. After the voltage transformer is installed in the handcart, the height of the power distribution cabinet is limited, resulting in the protection of the voltage transformer. There is not enough space for the installation of the fuse to be installed. [0003] In the current technology, it is for the maintenance of the handcart and the protection of the voltage transformer after the failure. For example, the price of the integrated voltage transformer is high, and the voltage transformer will be damag...
