I often use some power equipment in the house, so everyone knows that we still have this distribution box . Friends will now ask what is the distribution box production, what is the principle of distribution box production, distribution box production and installation What are the methods? Our distribution box production is useful. Friends and Xiaobian can understand the classification of our distribution box.
First, the introduction of distribution box production
Distribution cabinet (box) sub-power distribution cabinet (box) and lighting distribution cabinet (box), metering cabinet (box), is the final equipment of the power distribution system. The power distribution cabinet is the collective name of the motor control center. The power distribution cabinet is used when the load is relatively scattered and the circuit is small; the motor control center is used for the occasions where the load is concentrated and the circuit is more. They distribute the electrical energy of a circuit of the upper-level power distribution equipment to the nearest load. This class of equipment should provide protection, monitoring and control of the load.
Second, the production principle of the distribution box
1. The distribution box is assembled according to the requirements of electrical wiring. The switchgear, measuring instrument, protective appliance and auxiliary equipment are assembled in the closed or semi-closed metal cabinet or on the screen to form a low-voltage power distribution device. The circuit can be switched on or off with a manual or automatic switch during normal operation.
2. Cut off the circuit or alarm with the help of the protective device during fault or abnormal operation. The measuring instrument can display various parameters during operation, and can also adjust some electrical parameters to prompt or signal the deviation from the normal working state. Commonly used in various hair, distribution, and substation.
Third, the distribution box production method
1. The switchboard (box) is made of non-combustible materials; the production site and office with low risk of electric shock can be installed with open switchboard; in the workshop, casting and forging with high risk of electric shock or poor working environment Closed cabinets shall be installed in heat treatment, boiler room, woodworking room, etc.; in closed workplaces with conductive dust or flammable and explosive gases, closed or explosion-proof electrical installations must be installed.
2. The electrical components, instruments, switches and lines of the distribution board (box) should be arranged neatly, firmly installed and easy to operate. The bottom surface of the floor-mounted board (box) should be 5~10 mm above the ground; the center height of the operating handle is generally 1.2-1.5m; the board (box) is 0.8-1.2m in front of the board; the protection line is reliable; There shall be no exposed bare electric discharge outside the (box); electrical components that must be installed on the outer surface of the board (box) or on the switchboard must have reliable screen protection.
Fourth, the distribution box production classification
1. Fixed panel switchgear, often called switchboard or power distribution panel. It is an open switchgear with panel covering, the front side has protective effect, the back and side can still touch the live part, the protection level is low, and can only be used for industrial and mining enterprises with low power supply continuity and reliability requirements. The transformer room is used for centralized power supply.
2, protective (ie closed) switchgear, refers to a low-voltage switchgear that is closed except for the mounting surface. Electrical components such as switches, protection and monitoring controls of such cabinets are mounted in a closed enclosure made of steel or insulating material, mounted on a reliable wall or off the wall. There may be no isolation between each circuit in the cabinet, or it may be isolated by a grounded metal plate or insulating plate. Usually the door is mechanically interlocked with the main switch operation. There is also a protective table type switchgear (ie console) with controls, measurements, signals and other electrical appliances.
What is the distribution box production? We have learned from the article that some introductions and working principles of the distribution box production have been understood, then what are the methods for making and installing this distribution box and the classification of the distribution box production, small I hope that everyone can help everyone, we continue to pay attention to our decoration home network thank you for reading.
