Novel insert core interlocking mechanism

Abstract

The invention provides a novel insert core interlocking mechanism comprising a shell (1). An extension rod (2) penetrates through the shell (1) in the internal axis direction. A hanging plate (3) is arranged at the front end of the extension rod (2). The extension rod (2) is provided with a protruding part (4) and is provided with a resetting spring (5) at the front end of the protruding part (4). The resetting spring (5) is located in the shell (1). A rotatable sector plate (6) is installed in the shell (1) and a connecting plate (7) is hinged to the sector plate (6); the other end of the connecting plate (7) is in hinge joint with the extension rod (2). The shell (1) is provided with a groove allowing the sector plate (6) to protrude. An insert core (8) is installed on the outer side wall of the shell (1) on one side of the groove. One end of the insert core (8) is provided with an insert core handle (9) and a limiting pin (10). The novel insert core interlocking mechanism is convenient to use, occupies less space and facilitates assembly and disassembly.

Description

technical field [0001] The invention belongs to the technical field of electrical complete switchgear, and relates to an interlock mechanism, in particular to a novel core interlock mechanism. Background technique [0002] The high-voltage switchgear is the middle-end equipment of the power distribution system. It is used in the occasions where the load is relatively scattered and the circuit is less; the electric energy of a certain circuit of the upper-level power distribution equipment is distributed to the nearest load through the handcart in the cabinet. This level of equipment shall provide protection, monitoring and control of the load. [0003] In the existing high-voltage power distribution system, the handcart cannot move freely. Due to space problems, most of them are not equipped with mortise interlocking mechanism to prevent the handcart from moving freely; while some are equipped with interlocking mechanism, the interlocking mechanism is complicated and takes...

[0003] In the existing high-voltage power distribution system, the handcart cannot move freely

Due to space problems, most of them are not equipped with mortise interlocking mechanism to prevent the handcart from moving freely; while some are equipped with interlocking mechanism, the interlocking mechanism is complicated and takes up a lot of space. In a limited space, it is very It is difficult to install and overhaul. Therefore, when manufacturers use it, they often ignore the interlock mechanism, which will cause unnecessary safety hazards to operators.
