Abstract

The invention provides a transformer substation security and protection system having a write protection function and belongs to the technical field of security and protection. The transformer substation security and protection system comprises a Fresnel lens, an infrared sensor, a current-voltage converter, a voltage amplifier, a signal processor, a memorizer, a write protection circuit and an alarm circuit. The write protection circuit comprises a bleeder circuit composed of capacitors and resistors; the bleeder circuit is connected with an integrated reset chip; an output end of the integrated reset chip is successively connected with two phase inverters mainly composed of audions; output ends of the phase inverters are connected with the memorizer. The technical problems of loss or damage of system firmware programs in long-term use process of conventional transformer substation security and protection systems are solved; the service life of the system is greatly prolonged and the fault probability of the security and protection system is reduced.

Description

technical field [0001] The invention relates to a substation security system with write protection function, which belongs to the technical field of security. Background technique [0002] The substation is a place to change the voltage, which can realize long-distance transmission of electric energy. The stability of the substation is the basis for realizing stable power supply. Once illegal personnel enter the substation, it is possible to misoperate the equipment in the substation, and it is easy to affect the operation of the substation. normal operation. Therefore, substations generally need to send special personnel on duty, which requires a lot of manpower. [0003] The application number is 201210210989.X, and the application date is June 25, 2012. The invention patent application provides a comprehensive monitoring and management unit for the operating environment of an intelligent substation, including a single-chip microcomputer, a communication module, a power m...
