Abstract

The invention relates to the field of transformer structures, and particularly relates to a high-voltage direct-current energy supply transformer. The high-voltage direct-current energy supply transformer comprises a shell, an iron core, a high-voltage coil, a low-voltage coil and a silicone rubber sleeve, wherein the iron core, the high-voltage coil and the low-voltage coil are arranged in the shell, the iron core is fixedly connected with the shell, the low-voltage coil is wound on the outer side of the iron core, the high-voltage coil is arranged on the outer side of the low-voltage coil ina surrounding mode, the high-voltage coil is wrapped by a high-voltage shielding cover, the high-voltage shielding cover is clamped with the bottom of a suspension rod, and the suspension rod is connected with the shell. By means of the clamping mode, inconvenience of screw connection is avoided, rapid mounting and dismounting of the high-voltage shielding cover can be achieved, and meanwhile, damage caused in the mounting process can also be reduced.

Description

technical field [0001] The invention relates to the field of transformer structure, in particular to a high-voltage DC power supply transformer. Background technique [0002] The energy supply transformer can transmit 220V AC voltage to the high-voltage DC power grid, and provide 220V AC power to the high-voltage electrical equipment in it, which increases the reliability and convenience of transformer installation. [0003] The Chinese invention patent with the patent number 201310695456.X discloses a fully shielded high-voltage isolated voltage transformer, which optimizes the performance of the transformer. As the core components of the transformer, the iron core and coil need to be guaranteed not to be damaged during installation. Therefore, the requirements for installation are higher. The connection between the high-voltage coil and the lead pipe in the above-mentioned patent is connected by screws, and the screws need to be driven from the inside of the high-voltage...
