Two-wire direct drive monitoring system of high-voltage electric disconnecting switch

Abstract

The invention, which relates to the field of high-voltage electrical equipment in the electric power industry, discloses a two-wire direct drive monitoring system of a high-voltage electric disconnecting switch. The monitoring system comprises a master station microcomputer intelligent monitoring device, a substation operation execution unit, and a two-core connection cable connected between the master station microcomputer intelligent monitoring device and the substation operation execution unit. On the basis of monitoring mode innovation, a two-wire direct drive monitoring mode is realized physically and the system construction is simplified. Because of the novel and unique monitoring mode, local monitoring and remote monitoring are realized; the local monitoring includes measurement, signal, protection, control, and full-life-cycle monitoring and the remote monitoring includes telemetering, remote signaling, remote control, and remote regulation. With the monitoring mode, interlocking of the operating power supply and the monitoring power supply as well as real-time monitoring of the operation loop, operating conditions, and three positions is realized. The monitoring mode is the breakthrough of the monitoring mode of the high-voltage electric disconnecting switch and is pioneering; and reliable monitoring and maintenance-free operation and maintenance of high-voltage electric disconnecting switch are realized.
