power distribution box protective (i.e. closed) switchgear refers to a low-voltage switchgear whose sides are closed except the installation surface. The switch, protection, monitoring and control and other electrical components of this cabinet are installed in a closed shell made of steel or insulating materials, which can be reliably installed on or off the wall. There can be no isolation measures between each circuit in the cabinet, or various control modes of grounded metal plate can be adopted. During the experimental process, it can be smoothly switched or isolated by insulating plate. Generally, the door is mechanically interlocked with the main switch. In addition, there is a protective desk type switch cabinet (i.e. console), which is equipped with control, measurement, signal and other electrical appliances. The protective switch cabinet is mainly used as the power distribution device on the process site

GCK type low-voltage switchgear has high breaking ability, good dynamic and thermal stability, advanced and reasonable structure. GCK type drawer type distribution cabinet has flexible electrical scheme, strong seriality and universality, arbitrary combination of various scheme units and one cabinet body. The drawer has the advantages of large number of circuits, saving floor area, high protection level, safety and reliability, convenient maintenance and so on. The drawer is divided into 1/2 unit, 1 unit, 2 unit and 3 unit, with more than 9 units and 18 units in the cabinet. The drawer has closing, opening and experiment. At present, we do not directly produce graphene and draw out orientation, which can not only ensure normal work, but also safely overhaul the components in the drawer. From the pushing method of the drawer, it is basically divided into single dial and insert type, double dial and insert type and swing in type

Shanxi jintaiheng Technology Co., Ltd. shares the installation method of power distribution box for you: 1) the bottom surface of the cabinet (box) installed on the ground should be 50 ~ 100 mm higher than the ground; The height of the center of the operating handle is generally 1.2 ~ 1.5m; There are no obstacles within 0.8 ~ 1.2m in front of the cabinet (box). 2) The protective wire is reliably connected. 3) No bare electrified body shall be exposed outside the cabinet (box); The electrical components that must be installed on the outer surface of the cabinet (box) or on the distribution board must have reliable screen protection. Power and lighting distribution control box. Mostly closed vertical installation. Due to different use occasions, the protection grade of the shell is also different. They are mainly used as power distribution devices at the production site of industrial and mining enterprises

picture of Shuozhou high-quality emergency lighting box when the mains power is cut off or the voltage exceeds the power supply range, the controller starts the inverter, and at the same time, the output switches to find an appropriate position to install a tensile (compressive) force sensor to directly sense the load applied on the test piece. The switching device will immediately switch the mains power supply state to the inverter power supply to provide emergency power supply for the load equipment; When the mains power is restored, the emergency power supply will be restored to the mains power supply

Shanxi jintaiheng Technology Co., Ltd. has a team of experts with 16 years of front-line experience. Today, we share with you the relevant knowledge about ABB MDS series low-voltage distribution box: ABB MDS series low-voltage distribution box is mainly used for AC rated voltage of 660V and below, which can be used as branch distribution or load power control cabinet; The internal switch adopts isomaxs Series Molded Case circuit breaker produced by ABB, which has the advantages of small volume, high sectioning capacity, compact structure and good technical performance. The utility model has the advantages of simple installation, safe and reliable use. It is widely used in industrial and mining enterprises and civil buildings, high-rise buildings,, squares, entertainment and sports facilities, residential and other modern building power distribution devices
