Compact high-voltage wiring terminal and high-frequency transformer

Abstract

The invention discloses a compact high-voltage wiring terminal and a high-frequency transformer. The wiring terminal comprises an insulator satisfying a preset creepage distance. A first high-voltageconducting rod and a second high-voltage conducting rod are arranged in the insulator in parallel; the top ends of the first high-voltage conducting rod and the second high-voltage conducting rod extend out of the top surface of the insulator; the bottom ends of the conducting rods extend out of the bottom surface of the insulator; an upper insulating baffle plate is arranged between the top endsof the first high-voltage conducting rod and the second high-voltage conducting rod in the top surface of the insulator; a lower insulating baffle is arranged between the bottom ends of the first high-voltage conducting rod and the second high-voltage conducting rod on the bottom surface of the insulator; and the sizes of the upper insulating baffle and the lower insulating baffle both meet the creepage distance between the first high-voltage conducting rod and the second high-voltage conducting rod. According to the compact high-voltage wiring terminal, connection and safety protection of double paths of high-voltage incoming and outgoing lines in one terminal can be realized, and miniaturization and light weight of products with high-voltage interconnection requirements of cascaded high-capacity high-frequency high-voltage transformers are facilitated.

Description

technical field [0001] The invention relates to the technical field of electrical connection devices, and more particularly, to a compact high-voltage terminal and a high-frequency transformer. Background technique [0002] The high-voltage terminal is an electrical connection device in the electrical field. It is a key component of the transformer. It is mainly used to connect the high-voltage power grid to the transformer and connect the transformer. If the high-voltage terminal fails, the transformer will not work normally. [0003] At present, the commonly used high-voltage terminals are mainly used for the connection and connection of single-ended high-voltage, with low integration, mainly porcelain bottles. For the situation of dual high-voltage access and connected transformers, the technical solution is to select high-voltage terminals with corresponding voltage levels at the A and X terminals respectively. The existing technical solution occupies a large space and i...
