The invention provides a combined electrical isolating switch and a grounding switch. The isolating switch comprises a static contact, a moving contact, an electrically-operated mechanism, a rotation shaft, a pull bar insulator, a support insulator and an angle iron framework. The moving contact, the electrically-operated mechanism, the rotation shaft, the pull bar insulator, the static contact and the angle iron framework are shared by the grounding switch and the isolating switch. The static contact of the grounding switch is installed on the angle iron framework. A grounding switch static contact framework is fixed on an isolating switch angle iron framework. The angle iron framework is provided with an installation grounding hole. The invention is an isolating switch and grounding switch device which is applied in a connection and disconnection circuit in a power system medium voltage (6 kV, 10 kV and 20kV) power distribution network. The device has electrical and manual operation modes. Through applying the device, power supply reliability can be raised, labor intensity of a worker can be reduced, unsafe factors at aspects of electrical maloperation and traffic are avoided, and city power distribution network automation and transformer station automation are raised to a new technical level.
Description
Technical field [0001] The present invention is a kind of isolating switch and grounding switch equipment, which are used in medium voltage (6kV, 10kV, 20kV) distribution network of electric power system to connect and disconnect circuits. It has electric and manual operation modes and is mainly used for urban power distribution. Network line, box-type substation, centralized control substation power distribution system remote control stop and power transmission operation. Background technique [0002] The isolating switch and the grounding switch are one of the important equipment in the distribution network of the power system. At present, there are many types of isolating switches and grounding switches. The mechanisms are manually operated, and electric operation cannot be realized. The technical content is low and the operation is inconvenient. Especially, box-type substations, centralized control substations and urban power distribution lines need to go to the scene T...
