Abstract

The invention discloses a fast controller for a high-speed switch, and the method comprises the following steps: S1, connecting a debugging module with an upper computer, and carrying out the debugging and detection of the controller; s2, detecting and recording set values of zero-sequence current i01, A-phase line current ia1 and C-phase line current ic1; s3, zero-sequence current i02, A-phase line current ia2 and C-phase line current ic2 are collected and recorded in real time and compared with set values; and S4, transmitting a comparison result to a central processing unit, lighting a specified indicator lamp according to the result, and indicating personnel to troubleshoot according to the indication. According to the quick controller for the high-speed switch, through the arranged controller structure, when a fault occurs, short-circuit current is judged within two milliseconds, signal transmission and fault guidance are carried out through the state indicator lamp, and when a one-way grounding fault and an interphase short-circuit fault occur, switch-on and switch-off of the switch can be quickly controlled; and the switch body structure is matched to shorten the circuit fault duration and improve the power grid stability.

Description

technical field [0001] The invention relates to the technical structure field of switch control, in particular to a fast controller for high-speed switches. Background technique [0002] In recent years, with the expansion of the power grid scale and the improvement of the Internet level, the short-circuit impedance of the power grid has become smaller and smaller, and the level of short-circuit current has risen sharply. It is necessary to increase the configuration capacity of system equipment such as circuit breakers. When a short-circuit fault occurs in the system, it will increase the protection The coordination and difficulty of handling will cause serious hidden dangers to the safe, reliable and stable operation of the power system. When the short-circuit current exceeds the bearing capacity of the grid equipment, it will even bring disastrous consequences. In order to prevent short-circuit faults from harming the power system , it is necessary to take effective suppr...
