A rotary linear motor driven remote control platen

Abstract

The invention relates to a rotary linear motor-driven remote control pressing plate, which comprises a pressing plate assembly that can be pulled out by a pressing plate handle and can be rotated to return to a set angle, a box-shaped casing, a driving assembly and a state detection device arranged in the box-shaped casing, and a pressing plate. The front rod body where the handle extends into the box-shaped shell is provided with a limit column and a detection part. The driving component includes a guide rail sleeve and a rotating linear motor. The guide rail sleeve is provided with a guide rail and a detection hole on the side wall, and the front rod body of the pressure plate handle passes through. In the guide rail sleeve, and the limit column is embedded in the guide rail to guide the action of the platen handle. The rotating linear motor is connected with the front end rod of the platen handle to drive the platen handle to perform linear and rotational movements. The position of the detection hole is in line with the detection part. Adaptation, the state detection device is arranged on the side of the guide rail sleeve, so that the state detection device can detect the rotation and the throwing and retracting state of the pressing plate handle through the detection hole. The remote control platen has a high degree of automation, is easy to operate, and is safe and reliable.

Description

technical field [0001] The invention relates to the technical field of electric equipment, in particular to a rotary linear motor-driven remote control pressing plate. Background technique [0002] At present, in the power protection system, the pressure plates on the screen cabinets of most substations in China are manually operated, requiring operators to switch on or off the pressure plates on site. , resulting in electrical safety accidents. Some manufacturers propose a virtual pressure plate in the power protection system, which can realize automatic switch-on and withdrawal through microcomputer protection, but because the virtual pressure plate cannot provide a mechanical disconnection point, the safety is insufficient. [0003] Patent CN200810140099 provides an electric throwing and withdrawing device for protecting the pressure plate, which uses a motor and a cam mechanism to drive the pressure plate handle to move linearly, and uses friction to drive the pressure ...

[0002] At present, in the power protection system, the pressure plates on the screen cabinets of most substations in China are manually operated, requiring operators to switch on or off the pressure plates on site. , resulting in electrical safety accidents

Some manufacturers propose a virtual pressure plate in the power protection system, which can realize automatic switch-on and withdrawal through microcomputer protection, but because the virtual pressure plate cannot provide a mechanical disconnection point, the safety is insufficient

[0003] Patent CN200810140099 provides an electric throwing and withdrawing device for protecting the pressure plate, which uses a motor and a cam mechanism to drive the pressure plate handle to move linearly, and uses friction to drive the pressure plate handle to rotate, which solves the automatic throwing and withdrawing function of the pressure plate to a certain extent. The rotation of the handle is unreliable, the consistency is difficult to guarantee, the operation is not stable enough, once the action fails, there is no emergency unlocking function, etc.
