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.

Description

technical field [0001] The invention relates to the field of high-voltage electrical equipment in the electric power industry, in particular to a two-wire direct-drive monitoring system for a high-voltage electric isolating switch. Background technique [0002] The high-voltage isolation switch is one of the key equipment of high-voltage electrical equipment in the power industry. It mainly plays the following functions: (1) isolation, that is, to form a clear air gap with the equipment behind the belt, to ensure the maintenance safety of the power failure equipment; (2) to change the operation of the power supply system Way. The installation mode of the high-voltage isolating switch includes outdoor and indoor, and its operation mode includes manual and electric. The invention of the invention is aimed at the monitoring mode and monitoring mode of the high-voltage electric isolating switch. [0003] The existing monitoring modes of the high-voltage electric isolating switc...
