Process Control Equipment Fault Diagnosis and Maintenance Skills Training Platform

With the rapid development of science and technology, the degree of automation of process control equipment is getting higher and higher, the function of process control equipment is increasing, and the operation has become more and more complicated. Many smart instrument devices are gradually being widely used. Therefore The skills of equipment m--ntenance and equipment personnel should also be continuously updated. This improves the theoretical and technical level and actual operating skills of technical workers, and enhances the competitiveness of workers under the conditions of new forms. This set of equipment can improve the ability of equipment m--ntenance, m--ntenance and operators to handle problems on the spot.

Second, systemic characteristics

1. The object system is a st--nless steel frame, and all devices are designed by st--nless steel and aluminum alloy

2. The secondary measuring instrument of the sensor is installed on the object, which is convenient for students to perform various operations at the scene

3. The control part uses the st--nless steel mesh board. The on -site signal is directly received by the wiring terminal to the measuring instrument, which enhances the students' hands -on skills. At the same time, the wiring of the on -site instrument is more intuitive.

I. Overview

 

The "Mine Power Supply System Simulation Operation Device" is designed according to the typical mining power supply system, including the power supply part of the well, the part of the bottom of the underground, the power supply part of the recovery area, and the power supply part of the mobile substation. Through the tr--ning of this device, students can have a comprehensive understanding of the mining power supply system, can complete the pouring operation of the power supply system, and set up an accidental operation alarm. It can be used as a safety tr--ning and assessment of the mining electricity personnel.

2. Working environment: environmental temperature -5 ℃ ～ + 40 ℃, relative humidity <85%(25 ℃), altitude <4000m

 

3. Dimensions: 2400mm × 500mm × 2000mm

 

3. Device configuration

 

1. Device structure

 

The device adopts a cabinet structure, the cabinet adopts a double -layer sub -light dense -densely spraying structure, the panel uses a 2mm thick aluminum plate, and the text symbols on the panel are sprayed. The cabinet is equipped with six universal wheels for easy movement and fixation.

 

2. Power supply system

 

The front of the control screen is a typical mine power supply system simulation operation screen. The device uses dual power supply. The system is divided into five parts:

 

(1) The ground 35kV power supply part (dual power supply)

 

(2) 6KV power supply parts on the ground (sideline improved machine, m--n promotioner, ventilation, --r compressor, etc.)

 

(3) 6KV power supply part of the central transformer center (r--sing machine, rectification equipment, water pump, low -voltage power lighting, etc.)

 

(4) Part of the substation in the area (coal and electric drill)

 

(5) Power distribution part of the mobile substation of the mobile phone (coal mining machine)

 

The m--n switching elements in the system are switches and circuit breakers. The corresponding system diagrams on each switch operation element and circuit breaker components on the corresponding system diagram are embedded in the corresponding position of the system diagram. brake. Each power supply has a corresponding load and instruction
