A manual disconnecting and connecting device

Abstract

The invention belongs to the technical field of high-voltage electrical appliances, and discloses a manual disconnecting and connecting device, including a bracket, a driving mechanism, an opening and closing mechanism and a switching mechanism. The bracket includes two vertical frames and a horizontal frame, and the driving mechanism is fixed on a vertical frame. On the frame, the opening and closing mechanism includes a first terminal, a second terminal and a switch blade. The first terminal is installed on the driving mechanism, the second terminal is fixed on another vertical frame, and the switch knife is provided with a switching hole. , one end of the knife is rotatably connected to the first terminal, and the other end is engaged in the second terminal. When the switching mechanism is engaged in the switching hole, one end of the knife is relatively fixed to the first terminal, and the driving mechanism drives the gate The knife comes out from the second terminal, and when the switching mechanism is out of the switching hole, one end of the switch knife can rotate around the first terminal, and the other end of the switch knife can come out from the second terminal. The device can realize the opening and closing of the switch knife in two ways, which improves the speed of line maintenance and ensures the reliability and safety of power supply.

Description

technical field [0001] The invention relates to the technical field of high-voltage electrical appliances, in particular to a manual disconnecting and connecting device. Background technique [0002] At present, electric power equipment is usually required to be able to be remotely controlled by electric power, to realize data online transmission, and to feed back signals in real time. However, devices such as isolation knife switches that operate without load and can form an obvious isolation point after disconnection have not yet achieved remote control and data online transmission. When the line is in cold standby and maintenance state, it is necessary to form a visible and obvious disconnection isolation point for the power outage line. At present, the isolation knife switch, floor knife and other equipment of the power supply line need to be manually operated on site with an insulating operating rod.

However, devices such as isolation knife switches that operate without load and can form an obvious isolation point after disconnection have not yet achieved remote control and data online transmission.

When the line is in cold standby and maintenance state, it is necessary to form a visible and obvious disconnection isolation point for the power outage line. At present, the isolation knife switch, floor knife and other equipment of the power supply line need to be manually operated on site with an insulating operating rod. The operation process Relatively primitive and highly dependent on manual operation, there are certain potential safety hazards. At the same time, one operation task involves the closing and closing of multiple isolation switches. Manual operation not only affects the timely power transmission of the line, but also reduces the construction quality of the project.
