Embodiment Construction

[0024] The specific embodiments of the present invention will be further described below with reference to the drawings.

[0025] A three-station mechanism with opening and tripping that integrates manual and electric operation. It includes a frame. The frame is equipped with an isolation transmission device, an isolation output device, a ground transmission device, a ground output device, an energy storage device, and an electric The driving device and the opening and tripping device. The electric driving device is connected to and drives the isolation transmission device through a one-way input. The isolation transmission device is connected to one end of the energy storage device and can be rotated by manual input or motor drive to drive the energy storage The device stores energy. When the energy storage device turns to the maximum energy storage position, the energy storage is released to drive the isolation transmission device to continue to rotate. At this time, the isolati...

Abstract

The invention provides a three-station mechanism integrating manual operation and electric operation and with a breaking trip. The three-station mechanism comprises a rack, wherein an isolation transmission device, an isolation output device, a grounding transmission device, a grounding output device, an energy storage device, an electric driving device and a breaking trip device are arranged on the rack, the breaking trip device is linked with the isolation transmission device, the isolation transmission device drives the energy storage device to store energy, the stored energy is released todrive the isolation transmission device to continue to rotate and output a closing torque when the energy storage device rotates by maximum energy storage position, the breaking trip device rotates and the energy is stored, the isolation output device can be driven to reversely rotate by the isolation transmission device to achieve isolation operation after an energy storage state of the breakingtrip device is relieved, the grounding transmission device rotates and drives the energy storage device to store the energy, and the stored energy is relieved to drive the grounding transmission device to continue to rotate and output a grounding torque when the energy storage device rotates by the maximum energy storage position. The three-station mechanism is reasonable and reliable in structural design, is high in stability and long in service lifetime.

Description

Technical field [0001] The invention relates to an operating mechanism of a load switch, in particular to a three-station mechanism with opening and tripping integrating manual operation and electric operation. Background technique [0002] The function of the load switch is to realize the switching on and off of the circuit through the opening and closing action of the contact, and the opening and closing action of the contact is realized through the operating mechanism of the load switch. At present, the more common operating mechanism is the three-station operating mechanism. The three stations of the three-station mechanism are very clear, the middle is the isolation station, and the two ends are respectively the closing station and the grounding station. The isolation, closing and grounding status of the load switch can be realized through the operation of the three-station mechanism . The current three-station mechanism usually has a complicated structure, unstable perfor...
