| Abstract: | Compared with PTCR simples sintered by chamber furnace, several key environment adaptability parameters of PTCR components sintered by automatic progressive resistance furnace were studied. PTCR component is used in over-current protection of programmed exchanger. The result showing that PTCR sintered by double temperature range vertical furnace has a better R-T repeatability,smaller resistance change rate after high temperature storage, stability shockproof for current and lightning. It indicates safe reliability, long service time and good environment adaptability. |
