Description

Technical Field

[0001] The utility model relates to the technical field of low-voltage power cabinets, in particular to a low-voltage power cabinet with rapid expansion. Background Art

[0002] Low-voltage power cabinet is a common power equipment, which is widely used in power systems, especially in factories. It is an important equipment to connect various power equipment such as lighting, power and air conditioning to the power system.

[0003] Usually, the low-voltage power cabinet connects the incoming switch with the outgoing circuit breaker through a rectangular busbar. If the low-voltage power cabinet needs to add multiple outgoing switches after leaving the factory, the conventional solution is generally to replace the power cabinet. Replacing the power cabinet not only increases the cost of use, but also causes long-term power outages affecting production and life. At the same time, the equipment cannot connect the wiring port position and the internal circuit breaker to perform safe and reliable protection operations, which cannot meet daily use needs. Therefore, it is urgent to design a low-voltage power cabinet with rapid expansion to solve the above problems. Utility Model Content

[0004] The purpose of the utility model is to provide a low-voltage power cabinet with rapid expansion, so as to solve the problem proposed in the above background technology that the low-voltage power cabinet usually connects the incoming switch with the outgoing circuit breaker through a rectangular busbar. If there is a need to add multiple outgoing line switches after the low-voltage power cabinet leaves the factory, the conventional solution is generally to replace the power cabinet. Replacing the power cabinet not only increases the cost of use, but also causes long-term power outages affecting production and life. At the same time, the equipment cannot connect the wiring port position and the internal circuit breaker to perform safe and reliable protection operations, and cannot meet the daily use needs.

[0005] To achieve the above object, the utility model provides the following technical solution: a low-voltage power cabinet with rapid expansion, comprising a box body, a movable shaft is arranged on the front of the box body, a box door is movably connected to the front of the box body through the movable shaft, and a busbar channel frame is fixedly connected to the right side of the box body;

[0006] A protective cover is provided on the front of the bus channel frame, and a line collection seat is fixedly connected to the side of the protective cover.

[0007] Preferably, retractable side frames are fixedly connected to both sides of the bus channel frame, and the inner walls of the retractable side frames are provided with fixing rubber strips.

[0008] Preferably, three groups of wiring channels are arranged inside the bus channel frame.

[0009] Preferably, a layered rack is fixedly connected to the side of the box body, and three groups of outlet switches are evenly arranged on the side of the layered rack.

[0010] Preferably, a sealing frame is provided on the front of the box, and a layered plate is provided inside the box.

[0011] Preferably, a sealing rubber ring is provided on the inner wall of the box door.

[0012] Compared with the prior art, the beneficial effects of the utility model are:

[0013] The low-voltage power cabinet with rapid expansion can more conveniently carry out the expansion installation and use of the outgoing circuit breaker through the set box, bus channel frame, wiring channel, layer frame, outgoing line switch, sealing frame and layer board. First, the box is made into a modular design as a whole, and the outgoing line switch is set on the layer frame to be separated into three layers by the layer board. A bus channel frame is set on the right side of the box close to the outgoing line switch, and the wiring is carried out at the wiring channel inside the bus channel frame. At the same time, we install the non-perforated busbar system in the bus channel frame, and each layer is provided with a horizontal bus and a vertical quick connection interface. When it is necessary to add an outgoing circuit breaker, we can quickly add a layer of outgoing line circuit breaker without replacing the box, thereby reducing the additional cost for users to increase or replace the low-voltage power cabinet due to the need to increase production equipment, and at the same time, it can reduce the negative impact caused by the long production stoppage time caused by adding or replacing equipment, which reflects the practicality of the equipment design.

[0014] The low-voltage power cabinet with rapid expansion further improves the overall use effect of the equipment through the set box body, movable shaft, box door, bus channel frame, protective cover, wire collection seat, retractable side frame, fixing rubber strip and wiring channel. In daily use, the busbars discharged from the bus channel frame can all be inserted into the wire collection seat of the protective cover, and then the protective cover is docked to the front of the bus channel frame, and the fixing rubber strip is used inside the retractable side frame to perform rapid sealing and locking protection operations, so as to ensure the firmness of the wires at the outgoing switch at all times. At the same time, when the box door is closed by the movable shaft, the sealing rubber ring on the inner wall of the movable shaft is docked to the front of the layered plate, so as to perform protection operations for all outgoing circuit breakers inside the box, which reflects the comprehensiveness of the equipment design.
