Introduction:
With IEC60439-3 standard, LWHT series distribution box such as Mcb Power Distribution Box is attractive and durable, safe and reliable, which is widely used in various places such as factories, mansions, residences, shopping centers and so on.
Mcb Power Distribution Box Leakage phenomenon, I believe many people have heard this kind of phenomenon, mainly because of the ground strap connection, which leads to the leakage, and if you find the equipment appears the aging problem, then it must cause the leakage. When facing this situation, we should find reasons-the ground strap connection or the problem of aging equipment, we have to know how to solve it when the leakage happens in our daily life.
Protective (closed) switchgear is a low-voltage switchgear closed on all sides except the installation surface. The electrical components such as switches, protection, monitoring and control of this kind of cabinets are installed in closed enclosures made of steel or insulating material, which can be set on the wall firmly. There aren't isolation measures among the circuits in the cabinet, but grounding metal plates or insulating plates can also be used. Usually the door and the main switch are mechanically interlocked. In addition, there is a protective bench-type switch cabinet (control board), and it is equipped with electrical appliances such as control, measurement, and signals. The protective switch cabinet is mainly used as a Mcb Power Distribution Box device at the process site.
Function of distribution box :(1) reasonable distribution of electric energy, convenient operation of circuit opening and closing. It has a higher level of safety protection, and can intuitively display the status of the circuit. (2) It can play the role of configuring power supply. When the line fails, it is conducive to controlling the fault range and convenient to find out the fault point quickly and remove it in time, without large area power failure. In addition, the distribution box is convenient to place a variety of protective equipment, such as to prevent short circuit fuses (fuses), to prevent overload of the air switch, etc., can play a protective role in the line and electrical equipment. That is to say, put things together, convenient maintenance, inspection.
①The electrical appliances in the Mcb Power Distribution Box are first installed on the metal plate or installation strip, and then fixed in the distribution box as a whole, and the metal plate is electrically connected with the distribution box.
②The various electrical appliances in the distribution box and switch box shall be fastened according to the specified positions, and shall not be skewed and loosened on the installation board, and the distance between the electrical equipment and the surrounding of the board shall meet the requirements of the relevant technological standards.
③ The working neutral line in the distribution box is connected through the terminal board, and is separated from the protection neutral line (ground line) terminal board.
④ The connecting wire in the box adopts insulated wire, and the type and cross-section of the wire are strictly in accordance with the marked cross-section of the temporary drawing. The connection between various instruments uses insulated copper core wires with a cross-section of not less than 2.5mm2. The joints of the wires should not be loose, and there should be no exposed live parts.
