Title:
INTEGRATED INTELLIGENT ISOLATING SWITCH MECHANISM BOX
Document Type and Number:
WIPO Patent Application WO/2021/008168
Kind Code:
A1
Abstract:
An integrated intelligent isolating switch mechanism box, comprising a mechanism box housing, an output shaft, a coupling, as well as an execution unit, a control unit and function units provided in the mechanism box housing. According to the present invention, the use and installation of a torque detection sensor and an opening and closing in-place sensor improve the reliability and intelligence of equipment. Using an aviation plug as the interface for connecting the electrical part of the present invention to the outside improves the wiring and maintenance efficiency. In the present invention, a communication module is provided, which can upload a position signal of an isolating switch and an integrity self-check signal of a control protection loop of an operating mechanism box by means of a network, and can implement remote opening and closing operations of a double-grounded high-voltage isolating switch by means of the network. According the present invention, a PLC module is adopted to replace a conventional electrical element, and some components are modularly integrated, thereby reducing the installation time, and facilitating the operation and maintenance.
