Abstract

The invention discloses a fault prediction method of power transformation primary equipment. The method comprises the fault predication of a transformer, an isolating switch and a circuit breaker. The fault predication of the aspects of the transformer, the isolating switch, the circuit breaker and a metal oxide lightning arrester is mainly carried out, through the combination of various advanced technology of electronics, computer, photoelectricity, signal processing and sensing, and the fault predication and rapidness and accuracy of detection are realized. According to the method, the potential fault of power equipment can be early found, an early warning or prescribed operation is provided for the operation of the power equipment, and thus the stable and safe operation of a power grid is ensured.

Description

technical field [0001] The invention relates to the field of electric power, in particular to a fault prediction method for primary substation equipment. Background technique [0002] In the entire power grid system, the primary substation equipment plays the role of power supply access, distribution, voltage transformation, low-voltage power distribution, protection of power quality and output power, so it is the core of the entire equipment, and its overall operation The situation is very important to the safety of the entire power grid, so it is necessary to do a good job in its fault prediction and detection. The stability of primary substation equipment is related to the stability of the entire power grid. Therefore, for the operation and maintenance of primary substation equipment, it is necessary to master the fault prediction and detection methods of the equipment in the running state or even if the equipment is out of operation without dismantling the equipment...
