It can be used as a motor control center, power center, lighting control, main power distribution and power distribution device. This product is designed and developed based on the advantages of each distribution box. According to the installation method of the circuit breaker, it can be divided into three installation methods: plug-in type, fixed type and hybrid type. It can be used to realize switching, leakage, overload and short circuit protection of lighting distribution lines. Due to its structural problems, the existing HXM low-voltage distribution box has heavy equipment, low strength, low protection level, weak dustproof ability, large and heavy volume, poor anti-misoperation ability, very inconvenient installation and operation, complicated maintenance, Defects such as low reliability and unsatisfactory use effect, therefore, its improvement and innovation is imperative.

Contents of the invention

In view of the above situation, in order to overcome the defects of the prior art, the purpose of this utility model is to provide a low-voltage distribution box, which can effectively solve the problems of bulky, low-strength, low-level protection, weak dust-proof ability, bulky and bulky existing equipment. The ability to prevent misoperation is poor, and the installation and operation are very inconvenient.

The technical scheme solved by the utility model is that it includes a cabinet body, a panel, a column and a partition. The cabinet body is equipped with symmetrical columns, and the columns are respectively equipped with copper busbars, zero busbars, ground wires and multiple component mounting plates. The board is respectively equipped with isolating switch, circuit breaker, watt-hour meter and socket. The isolating switch is connected to the copper busbar through the insulated wire. Connected, the sockets are respectively connected to the zero bus and the ground wire, the control terminal of the isolating switch, the control terminal of the circuit breaker, the display of the watt-hour meter and the insertion end of the socket respectively protrude from the partition on the front of the cabinet, and the partition is directly in front of the cabinet. Top mounted with flip-up panels.

The utility model has the advantages of convenient and flexible installation, high strength, high protection level, strong dustproof ability, small volume and strong anti-misoperation ability, and is an innovation in low-voltage power distribution equipment.
