Abstract
The utility model pertains to the technical field of line deicing, and provides a line automatic deicing device. A reactance transformer is used to convert the line current into the operational power supply of a snow and ice detector. The snow and ice detector is used to detect the temperature and humidity of the surrounding environment of the line so as to determine whether the line reaches the ice-formation condition and output a corresponding control instruction. A heat-tracing cable is used to receive the control instruction outputted by the snow and ice detector, and when ice is formed on the line, the resistance of the heat-tracing cable is reduced, so the current is increased, and the heating value is increased, so that the deicing operation is performed on the line automatically, and heat-tracing cable can be switched on and switched off automatically according to the environmental conditions. An overvoltage relay is connected in parallel with the reactance transformer and the heat-tracing cable, and when the line is short-circuited, the overvoltage relay is in action to open the overvoltage normally-closed contact in the snow and ice detector, the voltage relay in the snow and ice detector is powered down, so the working circuit of the heat-tracing cable is opened, so that the damage on the line automatic deicing device can be avoided, and the problem that the ice coated onto the line is difficult to melt and the manual deicing operation is needed can be solved.
