Abstract

The invention relates to a novel fan junction box. The novel fan junction box at least comprises a cover plate and a box body. The junction box is characterized in that the box body is a square box. The side wall of the box body is provided with a wire outlet and a wire inlet which are used for being connected with cables. The interior of the box body is fixedly connected with a wiring terminal through screws. The cables, which pass through the wire inlet and the wire outlet, are respectively connected to the wiring terminal. The cover plate is fixedly connected with the box body through screws in a sealed mode. The junction box is safe and reliable in structure, simple, light, and good in waterproof performance. Meanwhile, the wiring terminal is arranged in the box body, so that the wiring terminal is protected. The waterproof performance of the junction box is improved.

Description

technical field

[0001] The invention relates to the technical field of transformers, in particular to a novel fan junction box. Background technique

[0002] The transformer cooling fan is mainly suitable for the radiator cooling system of extra-large, large and medium-sized transformers, which can increase the capacity of the transformer and prolong the service life of the transformer. Since the transformer needs to be installed and used in the open air, the cooling fan is required to have good outdoor working performance, and the electrical protection level must meet IP55.

[0003] DBF2 series transformer fans are manufactured according to the industry standard JB / T9642 of the People's Republic of China and are specially used for transformer cooling systems. The connection form of the fan is direct connection, the junction box is installed on the fan cylinder, the motor lead-out wire enters the junction box from the bottom of the junction box through the threading hole on...
