Problems solved by technology
Since the catenary is generally made of magnesium-copper alloy, which is in close contact with the ice layer and has a strong binding force, when the outdoor temperature is low, the deicing efficiency and implementation effect of only using air or water spray are not significant enough
Explosive deicing needs to set the blasting point in advance on the outside of the catenary and is a one-time deicing. The layout and installation are cumbersome and cannot be used multiple times.
The electric heating deicing method consumes a lot of electric energy. If the control is not good, it will damage the catenary, and the operation is inconvenient.
Short-circuit thermal resistance deicing must first cut off the normal power transmission of the catenary, which will cause the locomotive to stop running and cannot be widely used

Description
technical field [0001] The invention relates to the field of railway electrics, in particular to a vehicle-mounted microwave-vibration cooperative deicing device and method for an electrified railway catenary. Background technique [0002] The electrified railway catenary is exposed to the outdoors all year round and is extremely vulnerable to freezing rain. A large amount of icing of the catenary due to freezing rain will cause a series of problems such as line leakage, deformation, and damage to the pantograph. It is imperative to effectively solve the icing problem of electrified railway catenary. [0003] For the deicing problem of railway catenary, in addition to the manual and mechanical deicing method that requires a lot of manpower, the new deicing technology reported in the literature mainly includes the following methods. Vibration type, such as vibration deicing device with adjustable amplitude, frequency and contact pressure (CN201510681270.8), pneumatic vibrat...
