Description

A combined intelligent control isolating switch

technical field

The utility model relates to an isolating switch, in particular to a combined intelligent control isolating switch.

Background technique

Isolation switch (switch), that is, in the off position, there is an insulation distance between the contacts that meets the specified requirements and an obvious disconnection mark; For example, switching devices for currents under short-circuit).

Isolating switch (commonly known as "knife switch") generally refers to a high-voltage isolating switch, that is, an isolating switch with a rated voltage of 1kV and above, usually referred to as an isolating switch. The working principle and structure are relatively simple, but due to the large amount of use and high reliability requirements, it has a greater impact on the design, establishment and safe operation of substations and power plants. The main feature of the isolating switch is that it has no arc extinguishing ability, and can only open and close the circuit under the condition of no load current. The isolating switch is used at all levels of voltage to change the circuit connection or to isolate the line or equipment from the power supply. It has no current interruption capability and can only be operated after disconnecting the line with other equipment. Generally, there is an interlock device to prevent misoperation of the switch under load, and sometimes a pin is required to prevent the switch from being disconnected under the magnetic force of a large fault.

However, due to the long-time opening of the existing isolating switch, the temperature of the fuse in the switch will gradually rise, and it will always work when the temperature is too high, which will easily reduce the service life of the isolating switch. When the temperature is too high, the fuse will also be damaged. Burned, resulting in interruption of power transmission, inconvenient to use, and the existing isolating switches need to be manually opened and closed, manual opening and closing will increase the workload of workers, reduce work efficiency, and at the same time, manual opening and closing will have potential safety hazards of electric shock. Cause casualties, inconvenient to use.
