Automatic energy storage and switching-off and switching-on device

Abstract

The invention discloses an automatic energy storage and switching-off and switching-on device. The device comprises an energy storage spring, an energy storage rocker arm, a switching-on and switching-off rocker arm, a switching-on and switching-off spring and a switching-on and switching-off spinner, the switching-on and switching-off rocker arm is installed on a main shaft in a circumferential positioning mode, the energy storage rocker arm and the switching-on and switching-off spinner can be installed on the main shaft in a rotating mode within a preset angle, and the energy storage rocker arm and the switching-on and switching-off rocker arm are connected to a driving mechanism. The energy storage rocker arm is provided with an energy storage lock assembly for locking or unlocking, and the switching-on and switching-off spinner is provided with a spinner jacking assembly for jacking the opening and closing spinner in a normal state and being separated from the switching-on and switching-off spinner when the switching-on and switching-off rocker arm rotates to a preset position, so that the switching-on and switching-off spinner and the switching-on and switching-off rocker arm can rotate in a following mode through the switching-on and switching-off spring. Meanwhile, a spinner lock assembly is arranged to lock or unlock the switching-on and switching-off spinner; and the switching-on and switching-off spinner, the switching-on and switching-off rocker arm and the energy storage rocker arm are associated together, and the switching-on and switching-off spinner can only be touched by the energy storage rocker arm to rotate in the stored energy releasing process. According to the invention, rapid energy storage and switching-off and switching-on can be realized, and light weight of a product can be realized conveniently.

Description

technical field [0001] The invention relates to the technical field of electrical equipment, in particular to an isolating switch and its mechanism or parts, and more specifically to an automatic energy storage and opening and closing device. Background technique [0002] Photovoltaic system inverters usually need to be equipped with rotary isolating switches. Typical structures such as Santon’s products are mainly composed of contact level and mechanism level. The contact level is composed of multiple sets of coaxial moving contacts and static contacts. These moving contacts and static contacts are connected to the wiring terminals accordingly, and the mechanism level drives the moving contacts to rotate to clutch and separate from the static contacts, thereby realizing closing and opening of the circuit system. [0003] Ordinary rotary isolating switches are operated manually. When the opening and closing spring in the mechanism is compressed and stored energy during the o...

Problems solved by technology

For example, some products use the motor to directly drive the switch spindle to realize opening and closing, but the response speed is slow, especially the opening time is too long

In addition, there is also an automatic opening switch, which has an opening speed of milliseconds, but does not have an automatic closing function. It still relies on manual reset and closing operations, which limits the application range of the product.
