Embodiment Construction

[0017] An embodiment of the direct connection structure of the operating mechanism of the switchgear of the present invention is as follows Figure 1~Figure 2 As shown, for 550kV isolating / earthing switch. The direct-connected structure includes an isolating switch, a grounding switch, a fast grounding switch, a corresponding operating mechanism and a direct-connected transmission device. The isolating switch, the grounding switch, and the fast grounding switch are respectively provided with corresponding input shafts; There are multiple sets corresponding to the input shafts one by one, and output shafts are provided; the corresponding input shafts and output shafts are respectively connected by corresponding direct transmission devices. Among them, the isolating switch and the grounding switch adopt pure electric operation structure, and the fast grounding switch adopts the electric spring operating mechanism.

[0018] The direct-coupled transmission device includes a tra...

Abstract

The invention relates to an operation mechanism direct connection structure, comprising a switch mechanism and an operation mechanism; all phase switches of the switch mechanism are corresponding to the respective operation mechanisms; all the phase switches are provided with input shafts and all operation mechanisms are provided with output shafts; the operation mechanism direct connection structure also comprises a direct connection transmission device which is fixedly connected to the switch mechanism; the direction connection transmission device comprises a transmission device main body and a direct connection transmission shaft which is arranged inside the transmission device main body in a rotation manner; and the input shaft and the output shaft are connected through the direct connection transmission shaft in a transmission manner. Through above arrangement, the transmission path is simple, the direct connection transmission shaft does not have great energy loss, the power loss is small, transmission is reliable, the integral reliability and the stability of the switch device can be guaranteed and the connection and maintenance are easy.

Description

technical field [0001] The invention relates to a direct connection structure of an operating mechanism of a switchgear. Background technique [0002] GIS is the abbreviation of GasInsulatedmetal-enclosedSwitchgear, that is, gas-insulated metal-enclosed switchgear, which belongs to the auxiliary equipment of the power grid, and generally uses SF6 gas as the insulating gas. In recent years, with the acceleration of my country's economic construction, power grid construction has developed rapidly. Compared with open products, GIS has developed more rapidly because of its compact structure, high degree of integration, small footprint and other advantages, and it meets the requirements of the country to implement sustainable development. GIS switchgear includes switching mechanism and operating mechanism. Switching mechanism is generally divided into disconnector switch (DS), earthing switch (ES) and fast earthing switch (HES). Cost savings are of great significance. [0003]...
