Ring network cabinet operating mechanism

Abstract

The invention relates to an operating mechanism for ring network switchgear, which comprises a front clamping plate, a rear clamping plate, a main shaft, a closing component, an opening component and a closing / opening coil component, wherein the front clamping plate and the rear clamping plate are fixed in parallel, a middle plate is arranged between the front clamping plate and the rear clamping plate, and the main shaft is connected to the closing component and the opening component through the middle plate in a transmission way. The closing component comprises a closing tube, a closing spring, a chain wheel shaft, a chain and a cam, the opening component comprises an opening spring, a single-head crank arm, a double-head crank arm and an output shaft, and the closing / opening coil component comprises a coil shell, a coil, an output lever and a half shaft. The operating mechanism for ring network switchgear has the characteristics that the whole switchgear is capable of keeping reserved energy by changing the inner structure, the closing time is stabilized, the experimental data is captured more easily, the limit buffer function for closing / opening is added, the component wear is lowered, and the maintenance cost is lowered.

Description

technical field [0001] The invention relates to an operating mechanism of a ring network cabinet. Background technique [0002] With the development of the national economy and the advancement of science and technology, large-scale power consumption places such as industrial and mining enterprises, residential quarters, ports and high-rise buildings have begun to use ring network cabinets on a large scale; ring network cabinets have simple structure, safe and reliable operation, and low maintenance frequency. Low cost and low operating cost, compared with the traditional switchgear, the advantages are very prominent. [0003] The existing operating mechanism of the ring main unit mainly includes the operating main shaft, the cam, the energy storage motor, the operating device, etc. However, the operation mode of these ring main units is to close the switch directly when storing energy, without the function of closing maintenance and automatic reclosing , and the energy stor...

[0003] The existing operating mechanism of the ring main unit mainly includes the operating main shaft, the cam, the energy storage motor, the operating device, etc. However, the operation mode of these ring main units is to close the switch directly when storing energy, without the function of closing maintenance and automatic reclosing , and the function of energy storage and holding, and there is no buffer for closing, and no limit buffer for opening. These functional components are installed inside the inflatable ring network cabinet, which is very inconvenient for maintenance.
