Abstract

The invention provides an intelligent manipulation device of a ring main unit circuit breaker and a control method, aiming at solving the technical problems that the safety of an existing ring main unit is not high and the equipment management cost is high. The intelligent manipulation device comprises a microcontroller, a key switch, an LED (Light Emitting Diode) state indication lamp, a power supply module, a photoelectric isolation module, an input channel and an output channel, wherein the key switch, the LED state indication lamp, the power supply module and the photoelectric isolation module are connected with the microcontroller respectively; the input channel and the output channel are connected with the photoelectric isolation module respectively; the power supply module is also connected with the photoelectric isolation module. According to the intelligent manipulation device provided by the invention, the microcontroller with good performance is adopted so that an intelligent function is increased and gate opening and gate closing can be selectively carried out at a distance place or locally; the intelligent manipulation device has gate opening and closing state indication, spring energy accumulation indication and non-electric-quantity detection automatic gate opening. A signal input / output channel and a power supply of the system adopt an anti-interference technology, so that the anti-interference capability of the system is improved.

Description

technical field [0001] The invention relates to the field of intelligent control of circuit breakers, in particular to an intelligent control device and control method for a circuit breaker of a ring network cabinet. Background technique [0002] At present, with the rapid development of the power grid, in the construction of the smart grid, all kinds of switchgear are required to be automatic complete sets of equipment with remote operation functions. The early design of the ring network cabinet has no remote operation function, mainly manual operation, low security, high equipment management cost, and long response processing time. Therefore, in view of the current situation, an intelligent control device for the ring main unit is developed to meet the development needs of the power grid. Contents of the invention [0003] The present invention provides an intelligent control device and control method for a circuit breaker of a ring network cabinet, which can solve the ...
