  1.1, overview

  The power distribution cabinet is mainly used for power distribution and is the final equipment of the power distribution system. The power distribution cabinet is used in places where the load is relatively scattered and the circuit is small. In normal operation, the power distribution cabinet can be switched on or off by means of a manual or automatic switch. In the event of a fault or abnormal operation, the circuit or alarm is switched off with the aid of a protective element. With the help of our instrument, we can measure the parameters such as voltage, current and residual current of the power distribution cabinet.

  1.6 Model Description


  1.7 Application areas

  1.7.1 Factory

  The power distribution cabinet acts as a superior device for the power distribution/control box and functions to distribute power to the final power distribution/control box. In the factory, the power distribution cabinet can easily separate the circuits, which facilitates the maintenance and use of the power distribution/control box.

  1.7.2 Hospital

  The hospital has a large number of electrical equipment, so the power distribution cabinet is widely used in hospitals. It is usually installed in the floor distribution room, which is responsible for distributing electric energy to the equipment of each floor. At the same time, its energy measurement, leakage protection and other functions can better ensure the stable operation of the equipment.

  1.7.3 Shopping mall

  In order to meet the safety and comfort requirements of the mall, the mall is equipped with a large number of fans and pump equipment. The power distribution cabinets are installed in various areas of the mall to provide power for each device and to control the on and off of the primary power. Make power management and equipment maintenance more convenient and safe.
