Cooling wire for motor

Abstract

The invention relates to the technical field of electric power transmission and discloses a cooling wire for a motor. The cooling wire comprises a conductor, an asbestos layer and an insulating layerin order from the inside to the outside. A water storage cavity and a through hole are arranged in the asbestos layer. A plurality of cooling mechanisms is arranged at the upper part of the insulatinglayer with intervals. Each of the cooling mechanisms comprises a hollow block and a hollow column in order from the inside to the outside, and an inner cavity is formed between the hollow block and the hollow column. A vertical shaft is fixed in the hollow block, and a sliding plate is slidingly connected to the vertical shaft. The hollow block is divided by the sliding plate into an upper cavityand a lower cavity, the upper cavity and the lower cavity communicate through a slit arranged on the vertical shaft, and the lower cavity communicates with the through hole. The inner cavity is provided with a driving plate which is vertically and slidingly connected to the hollow column. The driving plate is provided with an air outlet check valve communicating with the upper cavity, an air inlet check valve which is fixed to the hollow column and communicates with the outside is arranged under the driving plate. The driving plate and the sliding plate are fixedly connected by a connection rod which is internally provided with an airway which communicates with the upper cavity and the outside. The cooling wire for a motor has a simple structure and can continuously cool the conductor inthe wire to avoid the burning of the wire.

Description

technical field [0001] The invention relates to the technical field of power transmission, in particular to a cooling wire for a motor. Background technique [0002] Wires are metal conductors used to transmit and distribute electrical energy. They are often used in urban power grids, outgoing lines of power stations, internal power supplies of industrial and mining enterprises, and underwater transmission lines across rivers and seas. In the process of social development, power lines and wires in transmission networks play an important role. [0003] As the link of power transmission, the wire is also used as the connection line between the motor and the power supply. Whether it is a civil motor or an enterprise motor, the greater the output power of the motor, the greater the load on the wires connected to the motor. The traditional motor wires are made of rubber-wrapped copper wires, etc. After the motor has been overloaded for a long time, the temperature of the wires ...
