Overvoltage monitoring protection device for automatic electromechanical device

Abstract

The invention discloses an overvoltage monitoring protection device for automatic electromechanical device. The device comprises a central processing system and a control box, one side of the control box is respectively hinged with a first movable door and a second movable door through hinges, and a locking mechanism is arranged in the control box. The back surface of one side of the inner wall of the control box is fixedly connected with a voltage sensor, and a time relay is fixedly connected to one side of the inner wall of the control box and is located on the front face of the voltage sensor. According to the overvoltage monitoring protection device for the automatic electromechanical devices, the voltage of a control device in the control box can be monitored, once an overvoltage phenomenon occurs, the related personnel are immediately notified to carry out the subsequent intervention work through a wireless transmission module, and meanwhile, the locking mechanism is arranged in the control box, so that the safety can be enhanced; and only related personnel can open the control box by using a magnetic card, so that a foundation is laid for the normal operation of the subsequent electromechanical devices.

Description

technical field [0001] The invention relates to the technical field of automatic electromechanical equipment, in particular to an overvoltage monitoring and protection device for automatic electromechanical equipment. Background technique [0002] Overvoltage refers to the long-term voltage fluctuation phenomenon that the AC voltage root mean square value rises under power frequency, exceeds 10% of the rated value, and lasts for more than 1 minute; the appearance of overvoltage is usually the result of the moment of load switching. Occurs when inductive or capacitive loads are connected or disconnected during normal use, for example: cutting off a large-capacity load or adding energy to a capacitor bank (overvoltage caused by excess reactive power compensation), the power system under certain conditions The abnormal voltage rise that exceeds the working voltage is an electromagnetic disturbance phenomenon in the power system. The insulation of electrical equipment can withst...

Problems solved by technology

[0005] Aiming at the deficiencies of the prior art, the present invention provides an overvoltage monitoring and protection device for automated electromechanical equipment, which solves the problem that the continuous overvoltage phenomenon is difficult to be known by personnel at the first time, thereby delaying the subsequent intervention work. At the same time, the control box There is no other safety protection structure, and non-operators are easy to open the door, which affects the safety of the equipment.
