Construction specification requirements for grounding

1. The shell, instrument panel, cabinet, box, box, cable tray, protective tube, bracket, base, and other normally uncharged metal parts of electrical instruments that may carry dangerous voltage due to insulation damage should be protected and grounded. For local instruments, switches, etc. with a power supply voltage not exceeding 36V, protective grounding may not be

The Method of Reducing Soil Resistivity by Grounding DCS System

1. Change the soil structure around the grounding body. Within a range of 2-3 meters of soil around the grounding body, adding substances that are not suitable for water and have good water absorption, such as charcoal, coke cinder, or slag, can reduce the soil resistivity to 1/5-1/10 of the original value. 2. Use salt

DCS system grounding method

1. Starting from firmware version V4.1, the S7-1200 CPU supports configuration control functions, making module configuration and installation more flexible. 2. Establish a dedicated and independent grounding network for the DCS system; 3. Set up a dedicated grounding network for DCS, which is connected to the electrical grounding network through a grounding wire. Due to

Detailed analysis of DCS system grounding

1、 Basic requirements for DCS system grounding DCS system grounding is to ensure that when there is a problem with the signal, power supply, or DCS system equipment entering the DCS system, the effective grounding system can withstand overload current and quickly introduce the overload current to the ground. The grounding system can provide a

Baikalai APROL (DCS) System and DCS Development Trends

1. Baikalai APROL (DCS) System 1.1 APROL Historical Review The Baikalai APROL process control system is a highly integrated, integrated, modular, and modern concept process control system based on the LINUX system platform. Since its launch in 1984, APROL has a 20 year history of application, covering process control industries such as petrochemicals, metallurgy, pharmaceuticals,

DCS system debugging plan

The on-site debugging work mainly involves checking and using the system software, and conducting configuration confirmation and functional testing on the application software. 1. Inspection before power on The cable insulation resistance meets the requirements (greater than 5M ohms). Check the cable insulation resistance test records and conduct spot checks and measurements if necessary. Verify

Large DCS control system

Functions and Characteristics of Large DCS Control System 1、 Has an open structure and strong scalability 1. Domain structure Adopting the concept of 'domain'. Divide the entire large-scale control system into several relatively independent subsystems using a high-speed real-time redundant network. Each subsystem constitutes a domain and is a fully functional DCS system. 2. Internationally

Definition and characteristics of DCS

DCS is the abbreviation of Distributed Control System, commonly referred to as Distributed Control System in China. It is a multi-level computer system composed of process control level and process monitoring level, connected by a communication network. It integrates 4C technologies such as computer, communication, display, and control. Its basic idea is decentralized control, centralized

DCS Overview

ARC consulting agency has released a world DCS market forecast report. The report predicts that the world DCS market will maintain a growth rate of 2.5% from 2002 to 2007, from $9.1 billion in 2003 to $10.3 billion. The main reason why the development speed of DCS is not high is due to the slowing
