Description

A multifunctional combined tool for a central cabinet

the

Technical field:

The invention relates to a multifunctional combined tool for a central cabinet, which belongs to the technical field of power system substation operation.

Background technique:

At present, most of the 10kV systems in substations use central cabinet equipment, and there are fewer and fewer open types. During the process of stopping power transmission in the central cabinet, operating handles are needed. There are three tools in the operation process of the central cabinet: the operating handle of the central cabinet , the grounding knife switch operating lever of the central cabinet, and the door key of the central cabinet. Due to the different manufacturers of the central cabinet in each substation, each of the above three tools has many models, and there are some differences. Therefore, in the process of tool preparation , it will delay time because of the need to repeatedly pick up tools, thereby reducing work efficiency and increasing power outage time; tool management with various models also increases management costs and difficulties, and when the operator in the station is suddenly lost, it needs to temporarily Looking for operating tools delays the switching operation and greatly reduces the reliability of power supply. How to adopt simple and easy methods to strengthen the management of operating handles and improve work efficiency is an important topic for substation operation management.

Invention content:

The purpose of the present invention is to overcome the deficiencies of the above prior art and provide a central cabinet multifunctional combined tool with simple and practical structure, strong versatility, easy management, reduced operating time, and improved work efficiency.

The purpose of the present invention can be achieved through the following measures: a multi-functional combined tool with a central cabinet, which is characterized in that it includes a handle, the handle is threadedly connected to the cast iron shaft, the cast iron shaft is connected to the rod head, and the rod head is provided with a rectangular connection slot, the operating head is provided with a rectangular connecting head matching the rectangular connecting slot, and the operating head is provided with an operating connector.

In order to further realize the purpose of the present invention, the operation connection part is an operation connection port in the operation head.

In order to further realize the purpose of the present invention, the operation connection port is in the shape of a square column or a hexagonal column.

In order to further achieve the object of the present invention, the operation connecting part is a cylindrical key connecting part with a groove.

In order to further realize the object of the present invention, the said operation connecting piece is a grounding knife switch connecting piece.

Compared with the prior art, the present invention can produce the following positive effects: the present invention is used as a general operating tool, and the rectangular connectors of various operating heads and the rectangular grooves on the rod body are all of uniform size, and all of them are taken out when matching each other. The required operating head can be connected and locked by inserting the standard rectangular connector into the rectangular groove. It includes operation heads of different types and sizes, which can realize the operation of different types of central cabinet operating mechanisms, greatly reducing the preparation time of operating tools required for power transmission of 10kV lines, and reducing the management cost of different types of operating tools. It improves the production efficiency, ensures the rapid and smooth switching operation, and ensures the healthy and stable operation of the power grid.
