Problems solved by technology

[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.

Embodiment Construction

[0014] The present invention will be further described below in conjunction with accompanying drawing, protection scope of the present invention is not limited to the following:

[0015] Such as figure 1 As shown, the new mortise interlock mechanism includes a housing 1. A telescopic rod 2 is interspersed in the axial direction of the housing 1. The direction in which the handcart moves to the working position is the front. The telescopic rod 2 There is a hanging plate 3 at the front end of the handcart. When the handcart moves to the working position, the hanging plate 3 will block the handcart, so that the hanging plate 3 and the handcart move forward together. The telescopic rod 2 is provided with a raised part 4 The telescopic rod 2 at the front end of the raised portion 4 is fitted with a return spring 5, the raised portion 4 blocks the rear end of the return spring 5, the return spring 5 is located in the housing 1, and the front side wall of the housing 1 blocks the bac...

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...
