An Electric Actuator for Lightning Surge Protection

Abstract

The invention discloses an electric actuator for lightning strike and surge protection, which comprises a cover plate, a groove is opened on the top of the cover plate, an indicator is installed inside the groove, and the groove is engaged with the indicator , the top of the indicator is provided with a gasket, the indicator is closely attached to the gasket, the top of the cover is provided with a frame, the top of the frame is provided with a fixing groove, and the outer wall of the frame is provided with a first A horizontal groove, bolts are installed inside the first horizontal groove, a connecting pipe is provided at the bottom of the indicator, the indicator is thermally connected with the connecting pipe, a limit block is arranged at the bottom of the connecting pipe, and the connecting pipe is connected with the connecting pipe The limit block is hot-melt connected. The bottom of the device indicator of the present invention has a protective pad, and the device as a whole can be disassembled, which is convenient for users to disassemble and maintain the internal parts of the device. At the same time, it has a plurality of gas discharge tubes, which can effectively convert high voltage into low voltage, effectively protect the device, and avoid internal parts. damaged by high pressure.

Description

technical field [0001] The invention relates to the technical field of electric actuators, in particular to an electric actuator for lightning surge protection. Background technique [0002] An electric actuator is a drive device that can provide linear or rotary motion. It uses some kind of driving energy and works under the action of a certain control signal. The actuator uses liquid, gas, electricity or other energy sources and passes through motors, cylinders or other The device converts this into drive action. [0003] However, the existing electric actuator is troublesome to disassemble and assemble the device during use, which leads to cumbersome disassembly and assembly process when repairing internal parts. At the same time, it does not have a gas discharge tube, which causes the internal parts to be easily damaged when the device encounters a lightning surge, and The heat dissipation function of the motor is poor, which leads to troublesome replacement and mainten...
