Electric control supporting and connecting device suitable for low-temperature storage tank and control method

The invention discloses an electric control supporting and connecting device suitable for a low-temperature storage tank and a control method. The electric control supporting and connecting device comprises connecting pieces, an electric control system and a combined type supporting rod; the two ends of the combined supporting rod are fixedly connected with the connecting pieces, the connecting piece at one end is a hot end, and the connecting piece at the other end is a cold end; and the electric control system is used for controlling connection or disconnection in the combined supporting rod so as to change or block a heat transfer path. The method can reduce heat leak of the storage tank passing through the supporting structure, and accurate electric control is achieved. 本发明公开了一种适用于低温贮罐的电控支撑连接装置及控制方法，电控支撑连接装置包括连接件、电控系统及组合式支撑杆；组合式支撑杆两端固定连接有连接件，一端连接件为热端，另一端连接件为冷端；通过电控系统控制组合式支撑杆内部的连接或断开改变或阻断传热路径。本发明能够降低贮罐通过支撑结构的漏热量并实现精准电控。
