Stationary non-destructive single-phase diverters and design and control methods for anti-icing and melting ice. The transmission line between the transmission power source and the electric load adopts a self-made heating wire with a coaxial cable structure. The non-destructive single-phase shunt for station is composed of shunt controller, transformer, inner conductor tap changer, inner conductor control motor, output tap changer, output control motor, microprocessor, and has three external connection terminals, which are inner conductor The connecting terminal, the connecting terminal of the outer conductor and the connecting terminal of the output, the three connecting terminals are respectively connected with the inner conductor, the outer conductor and the electric load. The microprocessor is respectively connected with the shunt controller, the inner conductor tap changer and the output tap changer to control the working states of the shunt controller, the inner conductor tap changer and the output tap changer. There are four structures of step-up auto-coupling transformers, step-down auto-coupling transformers, double-winding transformers, and three-winding transformers. The invention precisely controls the current of the inner conductor according to the needs, accurately controls the anti-icing and melting ice, and has low energy consumption and good effect.
Description
[0001] (1) Technical field [0002] The invention relates to an anti-icing and melting technology for power transmission lines, in particular to a non-destructive single-phase shunt for a station and a design and control method. [0003] (2) Background technology [0004] With the development of society and economy, in the environment of increasing power load applications, the requirements for exposed power lines are getting higher and higher. In the cold winter, the lines in many areas will freeze, causing damage to the lines. When the icing exceeds the bearing capacity of the line, serious accidents such as disconnection will occur. Therefore, deicing of power transmission lines in winter is essential and very important. In the prior art, ice melting technology is constantly improving. [0005] The application number is CN201810370549.8 "Self-made thermal conductor and heating equipment embedded with insulating and heat-conducting materials and its realization method", mak...
