Intelligent control apparatus and method for switch cabinet electric driver

Abstract

The invention relates to an intelligent control apparatus and method for a switch cabinet electric driver; the apparatus comprises a central processing unit, a motor control unit and a switch value control unit; the motor control unit comprises a motor control module and a protection module; the motor control module and the protection module are connected with the central processing unit separately; the switch value control unit comprises a switch value input module; and the switch value input module is connected with the central processing unit after the switch value input module is subjected to photocoupling. The intelligent control method comprises the steps that the motor control unit controls the electric driver to perform a corresponding operation according to a control instruction, and the motor control unit monitors the operating current maximum value and operating time in real time; when the operating current maximum value is greater than a preset locked-rotor current or the operating time is longer than a preset operating time, the motor is locked and an alarm is sent out; and if the motor runs normally, the operating current maximum value, the operating time and the voltage are recorded, and through a logical operation, the preset locked-rotor current and the preset operating time are adjusted in a self-adaptive manner. The control apparatus and the control method are highly centralized and high in intelligent level.

Description

technical field [0001] The invention belongs to the technical field of electric power system automatic control, and in particular relates to an intelligent control device and method for an electric driver of a switchgear, and is especially suitable for a multi-station electric driver of a medium-voltage switchgear. Background technique [0002] With the new round of rural grid transformation of the State Grid Corporation of China and the rapid development of the high-speed rail industry, the development of distribution network switches has been strongly promoted. Cable-based power supply has become the main form of urban and rural distribution networks. In order to improve the reliability and economy of power supply, connecting the power supply network into a ring-shaped ring network power supply has become the preferred method of cable-based distribution network. As the main equipment for changing network power supply, switchgear is widely used in urban power distribution n...
