The invention discloses an operating mechanism and relates to an operating mechanism of a disconnecting switch and an earthing switch. The operating mechanism comprise an operating panel, a middle partition board and a rear bent board, wherein a first chamber and a second chamber are defined by the operating panel, the middle partition board and the rear bent board, the operating panel, the middle partition board and the rear bent board are respectively installed and fixed with four sets of connecting threaded sleeves and connecting threaded rods, bearings are installed on the middle partition board and the rear bent board respectively, a major operating shaft is installed in the bearings, penetrates through the second chamber, and can move freely in the bearings, and the major operating shaft and an operating hole of the operating panel are coaxial; a welding indicator is installed on the major operating shaft and located in the first chamber, an interlocking disc is installed on the major operating shaft and located in the second chamber, and an operating connecting lever is installed at the tail end of the major operating shaft and is connected with an operating shaft of the disconnecting switch and an operating shaft of the earthing switch through corresponding connecting devices in a matched switch cabinet device. The operating mechanism is easy to operate, reliable, small in number of parts, low in cost and complete in interlocking.
Description
technical field [0001] The invention relates to an operating mechanism of an isolating switch and a grounding switch, in particular to an operating mechanism of an electrical switch. Background technique [0002] The isolating switch and the grounding switch are the two most used electrical appliances in the high-voltage switchgear. The isolating switch plays the role of isolating the power supply in the circuit, and the grounding switch grounds it when the primary circuit is powered off. When the isolating switch and the grounding switch are closed in the same power circuit, it needs to be operated with the supporting circuit breaker and switch cabinet according to certain operating procedures, and necessary anti-misoperation interlocking is required. The existing operating mechanism is bulky and the parts Numerous, complex and unreliable operating procedures. Contents of the invention [0003] Aiming at the deficiencies in the prior art, the purpose of the present inven...
