The utility model discloses a kind of high-reliability bypass switches, comprising: insulating frame, drive mechanism and switch device installed in insulating frame, and transmission assembly connected between drive mechanism and switch device;Transmission assembly includes insulating pull rod assembly and linkage lever, insulating pull rod assembly is provided with first pull rod, and first pull rod is distributed with the output rod of drive mechanism dislocation parallel;One end of linkage lever is hinged to the first fixed plate on insulating frame, and first fulcrum portion and second fulcrum portion are sequentially spaced from one end of linkage lever towards another end, first fulcrum portion is movably connected to first pull rod, and second fulcrum portion is movably connected to output rod;Drive mechanism is used to drive output rod to push linkage lever to rotate, and switch device is closed by insulating pull rod assembly drive.This utility model can reduce the failure risk caused by concentricity problem, reduce the force value required by drive mechanism, and structure is simple, significantly improve the reliability and stability of bypass switch work.

This utility model relates to the field of navigation aid technology, providing a navigation aid bracket and a multifunctional navigation aid. The navigation aid bracket includes a first frame and a second frame, with the second frame located above the first frame. The second frame has multiple mounting positions, which are suitable for photovoltaic modules to be installed circumferentially at an angle on the side of the second frame. The number of mounting positions is configured based on the vertical projected area of ​​each photovoltaic module, such that the ratio of the total vertical projected area of ​​the photovoltaic modules to the vertical projected area of ​​the first frame is 0.4–1.6:1. This utility model can improve photovoltaic power generation capacity without affecting the navigation aid's indicating function, ensuring the navigation aid's long-term continuous operation.

The invention relates to an optical storage all-in-one machine technology, and discloses an optical storage all-in-one machine control method and an optical storage all-in-one machine, through arranging a grounding relay, opening and closing of the grounding relay are controlled according to a power grid side state, a grounding mode can be flexibly adjusted, faults of equipment and a power grid are effectively isolated, the risk of equipment damage is reduced, and the safety of a system is enhanced. Meanwhile, the four contactors are arranged as the power grid contactors, so that the N line can be disconnected by using the contactors as required, and the method is safer and more reliable compared with the method of directly using a thyristor to control the on-off of the N line; and the thyristor and the power grid contactor are simultaneously arranged on one side, connected to the power grid, of the grid-connected and off-grid circuit, so that the switching speed of the thyristor is relatively high when grid-connected switching to off-grid switching is needed, and the system can be rapidly switched to off-grid power supply through the thyristor when the power grid is suddenly powered off, thereby avoiding load power failure caused by relatively low switching speed of the contactor. The invention aims to improve the electrical safety and the system stability in the use process of the optical storage all-in-one machine.
