Abstract

The invention discloses a temperature rise test system for a high-voltage switch gear. The temperature rise test system comprises a large-current generator, the switch gear, fiber temperature detection sensors, a temperature detector and an upper computer. The large-current generator is connected with the switch gear, and the fiber temperature detection sensors are arranged at different positions of the switch gear. The temperature detector is connected with the fiber temperature detection sensors to be used for collecting temperature signals of the fiber temperature detection sensors, and the upper computer is in two-way communication connection with the temperature detector. According to the temperature rise test system for the high-voltage switch gear, the fiber temperature detection sensors are adopted to conduct accurate distributed measurement on the overall temperature rise of the switch gear, and laboratory test for the overload capacity of the switch gear is achieved.

Description

technical field [0001] The invention belongs to the field of electric power, in particular to a temperature rise test system for high-voltage switchgear. Background technique [0002] The power system provides a strong energy backing for the sustainable development of the national economy, and the reliability of electrical equipment as a component of the power system is the guarantee for the safe operation of the power grid. With the change and development of power load, the original power transmission and transformation equipment is limited by technical conditions such as current carrying capacity and thermal stability limit, and the transmission capacity is greatly reduced. It has been difficult to undertake the power transmission task, let alone meet the needs of power users, especially in In the peak period of power consumption, under maintenance status or in the event of failure, the insufficient intercommunication capacity of the entire transmission system will cause p...
