The invention discloses a switch controller and a judgment method thereof. The switch controller comprises a control mechanism, a data acquisition mechanism and a switch body; the control mechanism comprises a controller mounted locally and a remote controller communicating with the controller; the controller comprises a shell and a control unit arranged in the shell; a power supply assembly, a set value adjusting button, a remote local switching button, a switching on button and a switching off button which are connected with the input end of the control unit are arranged on the shell; the input end of the control unit is further connected with the data acquisition mechanism; and the output end of the control unit is electrically connected with the operation driving end of the switch bodythrough an air connector. The switch controller adopting the structure and the judgment method thereof can quickly control a division switch to be switched on and switched off in case of a single-phase grounding fault and an interphase short circuit fault, and the quick switching off time is less than 30 ms to guarantee the electricity use safety of a non-fault user.
Description
technical field [0001] The invention relates to a switch control technology, in particular to a switch controller and a judging method thereof. Background technique [0002] When a fault occurs inside the 10kV overhead distribution line T connected to the user, if the fault occurs in the incoming line section, or if the fault occurs inside the user incoming line switch, if the protection action time limit is not coordinated with the protection of the substation outgoing line switch, it will cause the substation outgoing line The switch is protected from tripping. If the nature of the fault is permanent and the reclosing of the substation is unsuccessful, an accident in the medium-voltage user community will cause a power outage of the entire distribution line. This kind of spillover accident that is common in the distribution network will have a bad impact on society. Contents of the invention [0003] The purpose of the present invention is to provide a switch controller...
