Problems solved by technology
Due to the high operating voltage, it is impossible to directly detect the insulation of the equipment when the equipment is running
[0003] The traditional method is to shut down the equipment regularly every year, and test the insulation level by applying a voltage several times higher than the operating voltage to the equipment. Usually rely on the patrol inspection of the workers on duty, rely on observation and experience to determine whether the insulation is safe, and often find that the insulation level drops. Major safety accidents have been caused, causing equipment to burn and explode, causing vicious power outages and endangering the safety of the power grid and operators

The invention discloses high-voltage switch equipment. The equipment is provided with a central control unit (4); a busbar chamber, a breaker chamber and a cable chamber which all serve as ultraviolet, ultrasonic and ozone comprehensive sensors are respectively provided with a busbar chamber combined sensor (1), a breaker chamber combined sensor (2) and a cable chamber combined sensor (3); the busbar chamber combined sensor (1), the breaker chamber combined sensor (2) and the cable chamber combined sensor (3) are all connected with the central control unit (4) through a signal circuit. The invention also discloses a dynamic online comprehensive detection control method of insulation level of the high-voltage switch equipment. Due to the adoption of the technical scheme, through the special comprehensive sensors, ultraviolet rays, discharging sound and quantity of ozone in the air are measured simultaneously, the insulation level of the equipment is continuously monitored on line, and control protection is carried out so that insulation accidents are avoided.
Description
Technical field [0001] The present invention belongs to the technical field of high-voltage switchgear, and relates to the detection technology of its insulation level. More specifically, the present invention relates to a high-voltage switchgear. In addition, the invention also relates to the dynamic online comprehensive detection and control method for the insulation level of the high-voltage switchgear. Background technique [0002] Since the working voltage of high-voltage switchgear is above tens of kV, even as high as 1000kV, the insulation condition of high-voltage switchgear is a positive indicator related to the safe operation of the power grid. Due to the high operating voltage, the insulation condition of the equipment cannot be directly detected when the equipment is running. [0003] The traditional method is to shut down the equipment regularly every year, apply a voltage several times higher than the operating voltage to the equipment to test the insulation level, u...
