Description

Technical Field

[0001] The utility model relates to the field of generator water guide pipes, in particular to an insulating water guide pipe for generator stators and rotors. Background Technique

[0002] The insulating water guide pipe for the generator stator should have good insulation performance, temperature resistance and aging resistance. Due to its excellent chemical stability, good aging resistance and good electrical insulation performance, polytetrafluoroethylene is widely used to make the insulating water guide pipe of the generator stator.

[0003] During the actual operation of the generator, it is necessary to rely on the insulating water guide pipe to introduce cooling water into the stator coil to cool the coil, so as to ensure the long-term normal operation of the generator. However, during the operation of the generator, any temperature change may cause deformation such as stretching and bending of the insulating water guide pipe, seriously affecting the use of the water guide pipe.

[0004] The utility model aims to solve the technical problems existing in the prior art. Therefore, an insulating water guide pipe for generator stators and rotors is proposed. Content of the Utility Model

[0008] A reinforcement device is fixedly connected to the inner surface of the water guide pipe, and the water guide pipe is made of insulating rubber.

[0009] As a further scheme of the utility model: the reinforcement device includes a reinforcement rod, one end of the reinforcement rod is fixedly connected to the reinforcement plate, the reinforcement rod penetrates through the water guide pipe, the waterproof layer and the wear-resistant layer, and a number of air holes are opened on the cylindrical surface of the reinforcement rod.

[0010] As a further scheme of the utility model: the wear-resistant layer is composed of polyester fiber and polyester fiber intertwined with each other.

[0011] As a further scheme of the utility model: the waterproof layer is made of paraffin.

[0012] As a further scheme of the utility model: the tensile bars are made of high molecular polyethylene fibers.

[0013] As a further solution of the utility model: the reinforcing plate is a waterproof plate.

[0014] Compared with the prior art, the beneficial effects of the utility model are as follows: 1. By arranging a tensile bar inside the water diversion pipe, the tensile bar is made of high molecular polyethylene fiber, which enhances the bending strength of the tensile bar, thereby improving the tensile capacity of the water diversion pipe, that is, increasing the bending strength of the water diversion pipe.

[0015] 2. By fixedly connecting the reinforcing plate with the reinforcing rod, the reinforcing rod penetrates through the water diversion pipe, the waterproof layer and the wear-resistant layer, which can avoid the stretching caused by the softening of the rubber, that is, improve the tensile strength of the water diversion pipe.

[0016] 3. By arranging air holes inside the reinforcing rod, and at the same time, one end of the reinforcing rod extends out of the wear-resistant layer, that is, the air permeability of the water diversion pipe is improved, and the rubber aging of the water diversion pipe is avoided.
