Problems solved by technology

The permanent magnet mechanism has the advantages of simple structure and long life, but its disadvantage is that once the power is cut off or the controller is damaged, it cannot be closed; the spring operating mechanism is low in cost and has the characteristics of manual energy storage and electric energy storage. , the closing can be achieved by manual energy storage, but the service life is not as long as that of the permanent magnet mechanism
Therefore, these two operating mechanisms have their own advantages and disadvantages, and are also suitable for different occasions and requirements. Their products can only meet the requirements of a single user.

Embodiment Construction

[0012] Accompanying drawing 1 and 2 have provided the structural representation of the present invention. The vacuum switch includes a switch body (13), the controller (1) is located in the body, the spring operating mechanism (12) and the permanent magnet operating mechanism (2) are installed in the body and the driving link (6 , 10) is set on the switch main shaft (7) to drive its rotation. The permanent magnet operating mechanism (2) is connected with the drive connecting plate (6) through the connecting rod (5), and the driving connecting plate (6) is sleeved on the switch main shaft (7). In the spring operating mechanism (12), the closing cam (11) is installed on the camshaft (energy storage shaft), and the driving connecting plate (10) is sleeved on the switch main shaft (7). One end of the closing spring (9) is fixed on the end of the camshaft, and the other end is fixed on the bottom of the shell of the switch body.

Abstract

The invention belongs to a vacuum switch of a basic electrical unit device, an operation mechanism of the vacuum switch includes a spring operation mechanism and a permanent magnetic operation mechanism. The invention combines advantages of a spring operation mechanism and a permanent magnetic operation mechanism in a current technic, designs a vacuum switch with double operation mechanisms comprising a fucntion of the spring operation mechanism and a fucntion of the permanent magnetic operation mechanism. When a permanent magnetic controller has a fault, gate closing can be realized by manual energy storage conveniently.

Description

technical field [0001] The invention belongs to the technical field of basic electrical components, in particular to the improvement of the operating mechanism of a vacuum switch. Background technique [0002] The operating mechanism of the 12KV vacuum switch currently used in the market is mainly a spring operating mechanism, and there are also a small amount of permanent magnet operating mechanisms. The permanent magnet mechanism has the advantages of simple structure and long life, but its disadvantage is that once the power is cut off or the controller is damaged, it cannot be closed; the spring operating mechanism is low in cost and has the characteristics of manual energy storage and electric energy storage. , It can be closed by manual energy storage, but the service life is not as long as that of the permanent magnet mechanism. Therefore, these two operating mechanisms have their own advantages and disadvantages, and are also suitable for different occasions and req...
