Analog switch for 10kV boundary-type automatic terminal, and implementation method

Abstract

The invention discloses an analog switch for a 10kV boundary-type automatic terminal, and an implementation method. The switch comprises a signal transmission device and a signal processing device, wherein the signal processing device comprises a signal conversion circuit, a state display device, and a connecting terminal strip. The signal conversion circuit receives a switching-off DC voltage, a switching-on AC voltage and an AC working power signal, and then converts the switching-off DC voltage, the switching-on AC voltage and the AC working power signal into a switch position signal, an energy storage signal, a switching-off signal, and a switching-on signal for output. The state display device displays a switching state through a display according to the switching-off and switching-on signals. The switch is accurately connected with the 10kV boundary-type automatic terminal. During the remote switching of the terminal, the switch accurately display the switching state of the terminal, and feeds back the switching signal to a remote control signal. The above operation has no impact on the power supply of a distribution line, thereby effectively reducing the hidden troubles of remote control defects of distribution secondary equipment, avoiding an override trip event, and improving the power supply reliability.

Description

technical field [0001] The invention relates to the field of operation and maintenance of 10kV power distribution automation equipment, in particular to a simulated 10kV boundary-type automatic switch with remote control opening and closing functions, an analog switch suitable for 10kV boundary-type automation terminals and a realization method.
