Description

A power isolating switch with rain and lightning protection function

technical field

The utility model relates to the technical field of electric power isolating switches, in particular to an electric power isolating switch with the function of preventing rain and lightning.

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; in the close position, it can carry the current under normal circuit conditions and abnormal conditions within the specified time ( Switching devices for currents under such as 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. Function: 1. It is used to isolate the power supply and disconnect the high-voltage maintenance equipment from the live equipment, so that there is a clearly visible disconnection point between them. 2. The isolating switch cooperates with the circuit breaker, and the switching operation is performed according to the needs of the system operation mode, so as to change the system operation wiring mode. 3. Used to connect or disconnect small current circuits.

However, there are some problems in the use of the current power isolating switch. For example, when the current power isolating switch is outdoors, it is exposed to the air without certain protective measures.
