800kv intelligent circuit breaker

Abstract

The invention relates to an 800kV intelligent circuit breaker, which comprises a circuit breaker body, a protection measurement and control system and a state monitoring system, wherein the state monitoring system comprises a local control panel which is separated from the circuit breaker body and locally arranged; a state monitoring main light emitting diode (LED) is arranged in the local control panel; state monitoring sub-LEDs of corresponding phases are arranged in each phase of mechanism box; each state monitoring sub-LED is in communication connection with the state monitoring main LED; and the state monitoring main LED is connected with a state monitoring background system in a master control room through an optical fiber. The intelligent circuit breaker can comprehensively monitor equipment state, the phenomenon that the conventional equipment is required to be maintained at fixed time regardless of failures is avoided, a maintenance scheme can be reasonably determined according to an evaluation result which is obtained by system acquisition information, and state maintenance is realized. The adopted system scheme is simple in structure and general, and can be widely applied to intelligent switch equipment of other voltage classes.

Description

technical field [0001] The invention relates to an intelligent circuit breaker, in particular to an 800kV intelligent circuit breaker. Background technique [0002] Traditional circuit breaker systems such as figure 1 As shown, it consists of traditional high-voltage switchgear, protection room and main control room on site. The secondary signals and other signals in the traditional high-voltage switchgear (such as the switching value information of the auxiliary contact of the isolation knife) are connected to the protection cabinet and the measurement and control cabinet in the protection room through cables. The protection cabinet is equipped with relevant protection equipment, which is responsible for protecting the circuit breaker, and at the same time uploads the information to the background system in the main control room through optical fiber. The measurement and control cabinet is mainly used to collect secondary signals, upload them to the background system, and...
