Abstract: A terminal assembly, a top cover assembly, an energy storage device and electrical equipment are provided. The terminal assembly has an electrode terminal, an plastic member and a connector. A diametrical dimension of the electrode terminal is D, a minimum radial distance between the connector and the electrode terminal is d, and a maximum radial expansion dimension within a normal use range of the electrode terminal is P, 20?D/d?60, 0.01?P/D?0.03.

Abstract: An energy-storage device, an electrical apparatus, and a winding method are provided in the disclosure. The energy-storage device includes an electrode and a separator, where the electrode and the separator are stacked and wound to form a cell. The electrode is connected with a tab at an end of the electrode in a width direction of the electrode, where the tab includes a first tab and at least one second tab. The first tab is positioned adjacent to an end of the electrode in a length direction of the electrode, and the first tab defines a U-shaped notch. The U-shaped notch is configured to indicate a winding end position of the electrode, facilitating identification and winding automation.

Abstract: A manufacturing method of a top cover assembly, a top cover assembly and an energy storage device are provided. The method includes: providing a top cover plate, which is provided with an outlet hole; placing an electrode terminal above one side of the top cover plate to cover the outlet hole, so that a first space is defined between the top cover plate and the electrode terminal; placing a connector on the side of the top cover plate that is used for placing the electrode terminal. The connector has a first end portion surrounding a peripheral surface of the electrode terminal, and the connector has a second end portion in contact with the top cover plate.

Abstract: The present disclosure provides a method for running a drilling rig or a workover rig including a plurality of stands into a wellbore. In step 1, position information of the stands in a finger board area may be recorded with a control system. In step 2, the stands may be placed. In step 3, a position of a traveling block may be adjusted so as to move a power elevator to a second waiting position of a racking platform. In step 4, the stands may be pushed with the pipe racking device. In step 5, the second stand may be moved and stabbed in the first stand with an iron floor man. In step 6, a joint between the first stand and the second stand may be made up. In step 7, the traveling block may be moved downward. In step 8, the traveling block may be moved upward.
