Combined Motor Parameter Acquisition and Control Device

Abstract

The invention belongs to the field of motor control equipment, and particularly relates to a combination motor parameter collection and control device. The combination motor parameter collection and control device comprises a shell, a power input terminal and a power output terminal, wherein the power input terminal and the power output terminal are fixed to the shell. The shell is formed by buckling an upper shell body and a lower shell body. A power modulation module, a permanent magnet transmission contactor module, a permanent magnet transmission isolation module and a current conversion module are arranged inside the shell. A data collection and protection control module is arranged on the top of the shell. A control operation indicator lamp, a protection module indicator lamp, an operation interface unit, an operation display unit and an input power indicator lamp are arranged on the upper surface of the module. According to the combination motor parameter collection and control device, the motor protection, control, parameter collection and data transmission functions are integrated, all the functions of a motor control box and a data collection transmission terminal can be completed, meanwhile, a user just needs to connect an input power source and an output device, and the electric fault rate caused by wiring difficulty and complex electric wiring is greatly lowered.

Description

technical field [0001] The invention belongs to the field of motor control equipment, in particular to a combined motor parameter acquisition control device. Background technique [0002] In oilfield production, the motor on the pumping unit in the control box is generally used for control and protection. However, in the existing control box, various necessary components such as contactors and isolating switches are usually installed independently in the control box. , to realize their respective functions respectively. This traditional installation method of control components has problems such as cumbersome wiring and joint debugging, high failure rate, certain experience and time required for fault judgment and troubleshooting, and poor safety. Safety poses a threat; at the same time, this arrangement takes up a lot of space and requires a large control box, which is not only not conducive to the installation and transportation of the control box, but also leads to high c...
