Description

Technical Field

[0001] The present invention relates to the technical field of isolating switches, and in particular to a power isolating switch. Background Art

[0002] Isolating switches are mainly used to isolate power supplies, switch operations, and connect and disconnect low-current circuits. Its working principle and structure are relatively simple, but due to its large usage and high requirements for working reliability, it has a great impact on the design, construction 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 without load current. When the isolating knife switch is in the "open" position, there is a certain insulation distance and obvious disconnection mark between the contacts; when in the "closed" position, it needs to be able to carry the current under normal circuit conditions and the current under abnormal conditions (such as short circuit) within a specified time.

[0003] In order to drive birds away from staying on the isolating switch, a bird-repelling whistle is installed on the existing isolating switch to drive away birds. However, some birds may have poor hearing or are not sensitive to sound, so a good bird-repelling effect cannot be achieved. Therefore, corresponding improvements are made to address this problem.
