Description

A GIS equipment knife switch position conversion prompter

technical field

The utility model relates to a prompter for changing the position of a knife switch of GIS equipment. the

Background technique

More and more fully enclosed combined electrical appliances are put into grid operation. Its installation space and floor area are a few percent of the same level of substation. Reliability and safety are greatly improved. With the establishment of the operation team of the centralized control station, the substation mode with fewer people or no one on duty has become the general trend. Because of the greatly reduced installation space of the combined electrical equipment, the mechanism box of some knife switches and the central control cabinet are not in the same direction. During the switching operation, it is very difficult to check the mechanical position of the knife switch and the change of the signal indication. Centralized control operators are not permanently stationed at each station. There is a certain shortage in the familiarity and understanding of the equipment. I am not particularly familiar with the on-site equipment during operation, it is difficult to quickly find the mechanical position indication of the knife switch, and the switching operation does not allow checking a single signal indication. It will be very laborious, time-consuming and prolong the working time to check the position change of the knife switch on site. the

Contents of the invention

Purpose of the invention: The utility model provides a prompter for changing the position of the knife switch of GIS equipment. the

Technical solution : the utility model is realized through the following technical solutions:

A GIS device knife switch position conversion prompter is characterized in that: a position conversion relay is arranged at the opening and closing of the knife switch mechanical linkage, and the position conversion relay is connected to the language prompter.

The position conversion relay is divided into "open" position and "closed" position. When the knife switch mechanical linkage is opened, it contacts with the "open" position, and when it is closed, it contacts with the "closed" position. the

Advantages and effects :

The utility model provides a switch position prompter for GIS equipment, in which a position switch relay is arranged at the opening and closing of the mechanical connecting rod of the knife switch, and the position switch relay is connected with a language prompter;

The GIS equipment knife switch position conversion prompter is designed for the characteristics of difficulty in viewing the mechanical position of the knife switch and the change of signal indication. The prompter is composed of a position conversion relay, a voice prompter, etc., and is installed at the mechanical linkage of the knife switch. The position conversion relay is used to identify and prompt the opening and closing activities of the mechanical linkage of the knife switch. Example: When looking at the signal indication, you can hear "22111 knife switch close (point)";

The utility model can solve the problems of laborious, time-consuming and prolonging working time for viewing the mechanical indication of the position of the knife switch and the change of the signal indication of the position of the knife switch. It is more reliable to operate under the voice prompt. Make this product of GIS equipment more characteristic and humanized. It lays a solid foundation for less-person operation during centralized control. It adds a line of defense to the safe operation of the power system.

Description of drawings:

Fig. 1 is the structural representation of the utility model.

The specific embodiment: the utility model is further described below in conjunction with the accompanying drawings:

As shown in FIG. 1 , the utility model provides a switch position prompter for GIS equipment. A position switch relay 2 is provided at the opening and closing of the mechanical link 1 of the knife switch. The position switch relay 2 is connected to a language prompter 3 .

The position switching relay 2 is divided into an "open" position and a "close" position, and the knife switch mechanical linkage 1 is in contact with the "open" position when it is opened, and is in contact with the "close" position when it is closed. the

When the utility model is in use, when the mechanical connecting rod 1 of the knife switch is in the closed position, the mechanical connecting rod 1 of the knife switch triggers the position conversion relay 2, and the position conversion relay 2 controls the language prompter 3 to send out the information of "closed position of the knife switch". When the knife switch mechanical link 1 is in the position, the position switching relay 2 is triggered, and the position switching relay 2 controls the language prompter 3 to send the information of "knife switch position". The utility model is reasonable in structure, easy to use, and beneficial to popularization and application. the
