Embodiment Construction

[0015] Such as figure 1 with figure 2 As shown, an intelligent isolating switch includes an intelligent unit, a power unit and an isolating switch unit. The intelligent unit is composed of an electrical locking mechanism, a wireless temperature measurement system and a real-time video monitoring system. The wireless temperature measurement system includes several wireless temperature sensors. The temperature sensor is installed on the three-phase contact of the isolating switch 1. The wireless temperature measurement system and the video real-time monitoring system are connected to the signal transmission mechanism through the acquisition terminal. The signal transmission mechanism is an optical fiber or wireless mechanism; the power unit includes a solar energy storage battery pack, Remote controller 6, relay, delay switch, travel switch and electric mechanism 2, electric mechanism 2 is made up of electric motor, clutch, differential, universal converter and mechanical trans...

Abstract

An intelligent switch comprises an intelligent unit, a power unit and an isolation switch unit, wherein the intelligent unit comprises an electrical appliance locking mechanism, a wireless temperature measurement system and a video real-time monitoring system; the power unit comprises a solar energy battery pack, a remote controller, a relay, a delay switch, a travel switch and a power-driven mechanism, and the power-driven mechanism comprises an electric motor, a clutch, a differential mechanism, an universal converter and a mechanical driver; and the isolation switch unit comprises an isolation switch, an operation connection rod and a travel switch contact. By the intelligent switch, the remote control of the isolation switch and the misoperation-prevention locking rate are greatly improved, the operation risk of the isolation switch is reduced, and the intelligent switch has the characteristics of intelligent closing and opening, weak-current operation, remote vision, command control, on-site remote control, accurate data transmission, closeness, maintenance free, high safety and high reliability.

Description

technical field [0001] The invention relates to the technical field of electric power transformation and power supply, in particular to an intelligent isolating switch. Background technique [0002] The isolating switch is mainly used to reliably isolate the part of the high-voltage equipment that needs to be powered off from the live part to ensure the safety of maintenance work. The contacts of the isolating switch are all exposed to the air and have obvious disconnection points. The isolating switch has no arc extinguishing device, so it cannot be used to cut off the load current or short-circuit current. It is forbidden to pull the isolating switch with load, otherwise under the action of high voltage, a strong arc will be generated at the disconnection point, and it will be difficult to extinguish itself, which may cause arcing (phase-to-ground or phase-to-phase short circuit), burn equipment, endanger personal safety, and even cause serious accidents . In addition, t...
