Abstract: An electrical connection device has an electrical connector and a sealing member. The connector has an insulating housing which has an abutting face. The sealing member is provided to the housing and is adapted to be abutted between the face and a panel of an electronic device. The sealing member has an annular body, two first annular ribs, a plurality of second annular ribs and a plurality of positioning posts. The annular body has first and second surfaces and a plurality of penetrating holes penetrating the first and second surfaces. The first annular ribs respectively protrude from the first and second surfaces, and are adapted to respectively abut the panel and the face. The second annular ribs respectively protrude from the first and second surfaces, encircle the penetrating holes respectively, and are adapted to abut the panel and the face.

Abstract: A method and device for modeling a long-time-scale photovoltaic output time sequence are provided. The method includes that: historical data of a photovoltaic power station is acquired, and a photovoltaic output with a time length of one year and a time resolution of 15 mins is selected (101); weather types of days corresponding to the photovoltaic output are acquired from a weather station (102), and probabilities of transfer between each type of weather are calculated respectively (103); and a simulated time sequence of the photovoltaic output within a preset time scale is generated (104), and its validity is verified (105). By the method, annual and monthly photovoltaic output simulated time sequences consistent with a random fluctuation rule of a photovoltaic time sequence may be acquired according to different requirements to provide a favorable condition and a data support for analog simulation of time sequence production including massive new energy.

Abstract: A clutch mechanism for an energy storage device is disclosed. In an embodiment, the clutch mechanism includes a loading gear, a driving gear, a one-way bearing, a sleeve, and a gear shaft comprising a gear portion and a clutch portion. The gear shaft includes multiple spheres, and a push rod and an elastic element which are located in a cavity of the gear shaft. The push rod includes a groove and can slide in the axial direction of the gear shaft. A pressure block is fixed to the driving gear, the pressure block being able to push the push rod to slide in the axial direction of the gear shaft, so as to unlock or lock the sleeve and the gear shaft. A gas insulated circuit breaker employing such a clutch mechanism is also disclosed.
