Embodiment 1

[0037] see figure 1 , the oil-electric hybrid hot water deicing system carried by the helicopter of the present embodiment includes: a water tank 3, a spray gun 4 and a high-pressure water pump 2 for injecting the hot water in the water tank 3 into the spray gun 4 under high pressure; The resistance wire 6 for heating the water, the gasoline engine 1, the generator 5, the electric motor 8 and the storage battery 7, wherein, the gasoline engine 1 is used to provide power for the high-pressure water pump 2 and the generator 5 respectively; Wire 6 and motor 8 supply power and charge battery 7; motor 8 is used to provide power for high-pressure water pump 2; battery 7 is used to supply power to motor 8 and resistance wire 6 respectively. Under the premise of limited load capacity of the helicopter, using a combination of a gasoline engine with a relatively low power and an electric motor 8 can achieve a high-power deicing effect, reduce the weight of the gasoline engine 1, and inc...

Embodiment 2

[0056] This embodiment is an oil-electric hybrid hot water deicing system mounted on an Airbus 125 helicopter for overhead power transmission lines.

[0057] In this embodiment, the load capacity of the helicopter is 800kg except the driver. In order to ensure that the continuous deicing time is not less than 25min under the flow rate of 20L / min when the oil-electric hybrid is deicing, the water carrying capacity is 500kg. The weight of aluminum alloy plus inner heat preservation hot water tank 3 is 50kg. The installed gasoline engine 1 has a power of 800kW, the high-pressure water pump 2 has a pressure of 1.5Mpa, the generator 5 has a power of 700kW, the electric motor 8 has a power of 700kW, the battery 7 has a capacity of 1200AH, and the heating resistance wire 6 has a power of 660kW. The total weight of gasoline engine 1, high-pressure water pump 2, generator 5, motor 8, battery 7, control module 10, steering mechanism 9, and spray gun 4-level accessory connectors is 210kg...

Abstract

The invention discloses a gasoline-electric hybrid hot water deicing system for a helicopter and a control method thereof. The system comprises a water tank; a spray gun; a high-pressure water pump for injecting the hot water in the water tank into the spray gun at a high pressure; an resistance wire for heating the water in the water tank; an gasoline engine for providing power for the high-pressure water pump and a generator; the generator for supplying power to the resistance wire and an electric motor and charging a battery; the electric motor for providing power for the high-pressure water pump; and the battery for supplying power to the electric motor and the resistance wire. The gasoline-electric hybrid hot water deicing system can achieve a high-power deicing effect, reduces the weight of the gasoline engine and increase a water carrying capacity by using the combination of the low-power gasoline engine and the electric motor under the premise of a limited helicopter load.

Description

technical field [0001] The invention relates to the technical field of disaster prevention and mitigation in electric power systems, in particular to a hybrid oil-electric hot water deicing system carried by a helicopter and a control method thereof. Background technique [0002] Ice disaster is the natural enemy of safe operation of power grid. Ice-covered overhead transmission lines can easily lead to line galloping and insulator bridging, resulting in flashover, tripping and power outages, and in severe cases, line disconnection or even tower collapse, causing large-scale and long-term power outages. Existing ice-melting methods require a lot of manpower and material resources, and it is difficult to cover all lines. Some severe ice-covered micro-topographic areas, such as the transmission lines on the alpine pass terrain, are often heavily ice-covered, and the existing deicing methods are difficult to cover. The hot water sprayed by the helicopter can be used for deici...
