Problems solved by technology

At present, there are 43,000 small hydropower stations in operation in China, with an installed capacity of 34.66 million kilowatts. Hydropower stations put into operation before the 1990s account for a considerable proportion of the total installed capacity of domestic hydropower. After years of operation, the equipment has become obsolete and aging, and its performance indicators have deteriorated seriously. , which seriously affects the economic and safe operation of the power station

Embodiment 1

[0018] Embodiment 1: The capacity-enhancing transformation technology of the small and medium-sized hydroelectric generators of this embodiment, under the condition that the groove shape of the original stator core and the height dimension of the magnetic pole core cannot be changed, focuses on the following aspects:

[0019] ●Reduce the insulation thickness of the insulated flat copper wire in the stator coil.

[0020] Thin the insulation thickness of the main insulating powder mica tape of the stator coil.

[0021] ●Develop a new F-class stator coil insulation structure to reduce the unnecessary space occupied by the coil in the slot.

[0022] ●Thin the insulation thickness between turns of the rotor coil.

[0023] ●Develop a new F-class rotor coil insulation structure, improve the insulation form of the pole body, and reduce the thickness of the upper and lower insulation pads to reduce unnecessary space for the coil in the slot.

[0024] 1. Structural design features o...

Abstract

The invention comprises: a stator, a rotor and coil. The coil of said rotator and stator uses the copper flat wire made of the tong-ma epoxy glass mica and the non-coated Dacron glass copper flat wire. The capacity-increased modification technology comprises the stator modification technology and rotator medication technology. The F class stator coil insulation structure provided by the invention has an insulation layer made by means of integral hot-embossing, and its lower and upper edge is everted 90degree so as to reduce the space occupied by the coil; the thickness of the insulation between coil interturns is reduced.

Description

technical field [0001] The invention belongs to the technical field of water conservancy power generation, and in particular relates to capacity-increasing transformation technology of small and medium-sized hydroelectric generators. technical background [0002] Hydropower is a clean renewable energy. At present, there are 43,000 small hydropower stations in operation in China, with an installed capacity of 34.66 million kilowatts. Hydropower stations put into operation before the 1990s account for a considerable proportion of the total installed capacity of domestic hydropower. After years of operation, the equipment has become obsolete and its performance indicators have deteriorated seriously. , seriously affecting the economic and safe operation of the power station. The power station urgently needs to find a method with less investment and quick results to increase the capacity of the unit equipment, improve the output and efficiency of the unit, and solve the problem...
