| Abstract: | This paper introduces a novel automatic voltage stabilizing device for distribution transformer based on solid-state relay (SSR). The device consists of contactiess tap changing switch and voltage controller. Contactless tap changing switch adopts chaining SSR, and connects changing tap of transformer neutral point. Measuring signal is offered by transformer low-voltage measuring unit, and is sent to microcontroller. After comparing measured signal with setting voltage, the microcontroller gives on and off signs to make SSR run by driving circuit. With the aim of automatic changing tap of transformer and going step further stabilizing low-voltage of transformer, this paper mainly introduces the characteristics of SSR, the structure and performance of the device, the adjusting principle and data analysis of experimentation of chaining SSR in contactiess tap. |
