The semiconductor corrugated plate is an important material for fixing the coil in the stator core slot of the turbo generator generator. In the past, due to insufficient stress of the semiconductor corrugated plate, the coil would come out of the slot, or Insufficient mechanical strength of the semiconductor corrugated board leads to damage of the corrugated board and accidents
[0003] In addition, the semi-conductor corrugated board of the existing steam turbine generator is not suitable for the use of the steam turbine generator in nuclear power.

Abstract
The invention discloses an F grade semiconductor corrugated plate for nuclear power. The F grade semiconductor corrugated plate is prepared from the following raw materials by weight: 120-160 parts of N, N'-4, 4'-diphenylmethane bismaleimide; 20-60 parts of 4, 4'-diaminodiphenylmethane; 50-80 parts of N, N'-dimethylformamide; 80-120 parts of toluene; 100-240 parts of 6101 epoxy resin; 180-300 parts of alkali-free woven roving; 60-140 parts of non-woven fabric; 180-300 parts of alkali-free plain cloth; and 12-28 parts of acetylene black. The invention also discloses a preparation method of the F grade semiconductor corrugated plate for nuclear power. The semiconductor corrugated plate provided by the invention is used between a stator bar and an iron core of a nuclear power generator to adjust the side clearance in a generator stator slot, and is used for grounding of stator bar surface voltage. The operating temperature reaches 150DEG C, and the service life reaches 15 years or more. The semiconductor corrugated plate provided by the invention has the advantages of uniform resistance distribution, small resistance range of 104-105ohm, and excellent elastic support force and thermal aging stress performance after long-term use under high temperature.
Description
technical field [0001] The invention relates to the technical field of semiconductor corrugated plates for steam turbine generators, in particular to an F-class semiconductor corrugated plate for nuclear power and a preparation method thereof. Background technique [0002] When the turbogenerator is running, there are two main types of force on the stator bar in the stator core slot: one is the electromagnetic force generated when the generator is running, and the other is the load change or accident (caused by temperature change or directly generated) force impact. This makes the stator bar in a state of vibration, creep and displacement for a long time. In order to prevent the wear of the main insulation of the stator bar caused by this state, which will cause major accidents such as electrical corrosion or even wire breakage, generally choose the same semiconductor corrugated plate to fill the wire bar Between the side and the stator core, so the semiconductor corrugated...
