The invention discloses a load self-adaptive waste gas torch ignition device and a control system, relates to the technical field of torch ignition devices, and is mainly used for coping with combustible waste gas load fluctuation scenes in the industrial production process, realizing stable and efficient combustion of waste gas and avoiding resource waste and environmental pollution. Specific to a gas inlet mode in a high-pressure / low-pressure gas channel, self-adaptive actions are performed according to gas pressure fluctuation, and the actions comprise that a rotary encoder of an action fine adjustment assembly indirectly feeds back gas flow of the low-pressure / high-pressure gas channel by detecting the rotating speed of a transmission rod and combines initial gas pressure, a waste gas pressure change value and gas flow data, so that the gas flow is adjusted. The micro-drive motor is controlled to drive the transmission rod to rotate, the first transfer gas sheet drives the high-pressure gas channel forward / reverse gas sheet to rotate directionally, the overlap ratio of eccentric gas ports of the gas sheets is changed, the higher the overlap ratio is, the smaller the gas flow resistance is, the higher the gas pressure is, and otherwise, the smaller the gas pressure is, precise adjustment of the gas pressure of the high-pressure gas channel is achieved, and waste gas load changes are adapted.

The application belongs to the technical field of power generation, and particularly relates to a power supply device for automobile range extension, and more particularly to a direct-current power generation system and a working method thereof. The direct-current power generation system acquires the power of a power generation part in real time through a control module. When the power changes, the control module controls a pressurizing part to pressurize a power part cooling loop, and controls a connecting part to connect the power part cooling loop and the power generation part cooling loop, so that the high-pressure gas in the power part cooling loop enters the power generation part cooling loop, the gas pressure in the power generation part cooling loop is increased, the boiling point of the cooling liquid in the power generation part cooling loop is increased, and the cooling requirements of the power generation part and the power part are simultaneously met. When the power of the power generation part changes, the gas pressure in the power generation part cooling pipeline is increased, the boiling point of the cooling liquid therein is increased, and the cavitation effect caused by the local temperature rise and boiling of the cooling liquid due to the local eddy current caused by the power change is avoided.

This invention discloses a 72.5kV single-tank environmentally friendly gas-insulated GIS structure for offshore wind turbine towers. It connects to the transformer on the wind turbine generator side at the top and to the submarine cables on both sides of the wind turbine tower at the bottom. A second chamber with a two-stage pressure differential enhances the gas pressure and insulation capacity within the insulation tank, solving the problem of insufficient mechanical lifespan of existing vacuum bubble corrugated pipe technology in 5-6 MPa high-pressure gas environments. The three-position switch adopts an innovative L-shaped direct-acting double-contact structure, fully utilizing the three-dimensional space. The insulation disc uses a dielectric constant functionally graded material to improve overall insulation performance. A shock-resistant base combining gas springs and hydraulic cylinders achieves vibration reduction and energy dissipation. The insulating gas is clean air, complying with carbon neutrality policies and representing the future development direction. Integrating all high-voltage switches into a single tank significantly reduces size, resulting in a compact structure, saving floor space, facilitating installation within offshore wind turbine towers, and minimizing the risk of gas and electrical leakage, thus offering a cost advantage.
