Mechanical and electrical installation tends to focus on mechanical and electrical equipment, with industrial equipment being more commonly used. Electrical installation tends towards building intelligence and civilian equipment.
1、 Mechanical and electrical installation generally includes the installation of equipment, lines, and pipelines for industrial, public, and civil construction projects, transformer and distribution station projects of 35 kV and below, and the production and installation of non-standard steel components. Mechanical and electrical installation is a relatively large-scale project, and some large enterprises may relocate. It takes nearly six months to implement a project, and the technical requirements for installation are also quite high. The engineering content includes boilers, ventilation and air conditioning, refrigeration, electrical, instrumentation, motors, compressor units, and equipment such as broadcasting, film, and television control.
2、 Basic handover acceptance, equipment positioning, busbar installation, cable laying, control system equipment installation, and control line laying. High voltage equipment needs to undergo relevant tests and tests as required by regulations, such as insulation, absorption ratio, phase sequence, transformer oil, etc., and provide test reports. After that, debugging can be carried out. Control system action debugging can be done first, followed by electrical debugging, and finally load debugging. The control electrical equipment can be progressiveness simulated during commissioning, provide some analog signals, and check whether the associated actions are accurate and timely. Finally, prepare the handover documents, which should be synchronized with the project progress and signed off in a timely manner.
