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.

Embodiment approach
[0091] According to the above system solution, the present invention specifically provides the following mechanical structures to meet the above design requirements.
[0092] see Figure 2-Figure 39 , shows the complete machine, main mechanism and part structure of the isolating switch product of the present invention. The isolating switch is a small intelligent isolating switch product that can realize remote opening and closing operations and has rapid opening capabilities, and will be described in detail below.
[0093] 2.1 Machine structure
[0094] see Figure 2-Figure 5 , and see also Figure 6-Figure 30 , shows the product structure of the isolating switch of the present invention. The isolating switch includes a mechanism level 100 and a contact level 200 , wherein the mechanism level 100 is used to operate the contact system in the contact level 200 . The mechanism level 100 has a rotary action mechanism 130, which includes an energy storage mechanism 131 and a s...

The invention discloses an isolating switch. The isolating switch has and only has three states in a steady state: state 1: energy storage OFF, switching-on and switching-off OFF and manual OFF; state 2: energy storage ON, switching-on and switching-off OFF, and manual OFF; and state 3: energy storage ON, switching-on and switching-off ON and manual ON. When the current state is the state 1, an energy storage mechanism can be manually or automatically operated to store energy; when the current state is the state 2, a switching-on and switching-off mechanism can be manually or automatically operated for switching off; when the current state is the state 3, the energy storage ON can be maintained, and the switching-on and switching-off mechanism is manually operated for switching on, or the energy storage mechanism is automatically released to switch the energy storage ON to the energy storage OFF, so that the energy storage mechanism drives the switching-on and switching-off mechanism for switching on; and in the stored energy releasing process, the switching-on and switching-off mechanism can be driven only by the energy storage mechanism. 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 present invention relates to the technical field of electrical equipment, in particular to an isolating switch and its mechanism or components, and more specifically to an isolating switch. 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 operation, the contact of t...
