Abstract

The invention provides an intelligent monitoring system for multiple operation states of a switch cabinet of a transformer substation. The system comprises an MCU, and a local discharge sensor, a temperature sensor, a humidity sensor, a voltage sensor, a current sensor, a power module, a FLASH memory, a Bluetooth module, an RS485 module and a GPRS module which are connected to the MCU. The invention further provides an intelligent evaluation method for the multiple operation states of the switch cabinet of the transformer substation. The evaluation method adopts fuzzy and evidence reasoning fusion, the intelligent evaluation is carried out on the multiple operation states of the switch cabinet according to multiple parameters, and an intelligent evaluation system for the multiple operations states of the switch cabinet, which corresponds to the evaluation method, is embedded into the MCU. According to the system and the method, the operation state inside the switch cabinet can be monitored online, the operation state of the switch cabinet is intelligently evaluated in real time, and the characteristics of high sensitivity and convenience for installation are provided, so that the reliability of power supply can be guaranteed, the timeliness of electricity utilization of a power user can be ensured, and the electricity consumption requirement of the user is met, and thus the management level of safe production of a power grid enterprise is improved.

Description

technical field [0001] The invention relates to the technical field of substation equipment, in particular to an intelligent monitoring system and evaluation method for multiple operating states of a substation switch cabinet. Background technique [0002] The high-voltage switchgear is the pivotal equipment between the power system substation and the power distribution system. It plays the role of on-off, control or protection in the system. The high-voltage switchgear manufacturing industry is an important part of the power industry. Once it fails, it will seriously affect the power supply reliability of the power system. [0003] The national grid safety operation analysis report shows that among the 6-10kV switchgear accidents in the power system, the faults caused by current-carrying and insulation damage account for the largest proportion of the total. When the load of the switchgear exceeds the rated load, its internal temperature will rise, which will seriously cau...
