Technical Field

[0001] The utility model relates to the technical field of power distribution cabinets, in particular to an MCC cabinet which is easy to configure. Background Art

[0002] MCC (Motor Control Center) control cabinet, that is, the motor control center consists of at least one low-voltage switchgear and related control, measurement, signal, protection, regulation and other equipment. The manufacturer is responsible for completing all internal electrical and mechanical connections and is a combination of structural components that are completely assembled together.

[0003] In the related art, when configuring an MCC cabinet in a workshop or adding new equipment controlled by the MCC cabinet in the workshop, staff often need to refer to the on-site assembly drawings to determine information such as the rated power and rated current of different equipment and the model of the circuit breaker configured in the MCC cabinet. However, due to the site requirements, in order to facilitate management and prevent the loss and leakage of drawing information, various on-site process flow charts, equipment circuit diagrams and control logic diagrams are often bound into a single instruction book.

[0004] However, in related technologies, since various drawings are collected and bound into one volume, the content of each drawing is redundant, and on-site configuration often requires the cooperation of multiple people to complete wiring, debugging and other tasks. Different staff members have different divisions of labor and need to refer to different drawings. This makes it difficult to schedule the instructions, affecting the slow progress of on-site construction and maintenance and the complicated process. Utility Model Content

[0005] In view of this, the utility model provides an MCC cabinet that is easy to configure to solve the problem of slow construction and maintenance progress and complicated processes due to difficulties in scheduling instructions while preventing the loss and leakage of drawing information.

[0007] Beneficial effects: Multiple control boxes are set on the cabinet body for installing circuit breakers of control equipment to realize the control of on-site equipment. An on-off switch is provided on the door of the control box to facilitate the control of the on and off of the circuit breaker and realize the function of the MCC cabinet. A drawing cabin is set on the lower side of each control box of the cabinet body. The drawing cabin is used to store relevant drawings such as equipment circuit diagrams and on-site layout drawings corresponding to the equipment controlled by the corresponding control box. Before the staff inspects the on-site equipment, they first cut off the power to the relevant equipment through the MCC cabinet, take out the relevant drawings, and carry out inspections according to the instructions of the drawings. During on-site construction, the staff responsible for different equipment can take out the drawings related to the responsible parts from different drawing cabins and work at the same time. The detection sensor set in the drawing cabin is used to detect whether the drawings are placed back in the drawing cabin, and when the drawings are not returned to the drawing cabin, the switch is closed, that is, the corresponding equipment cannot be started, thereby improving the management of the drawings and preventing the possibility of loss or leakage of drawings.

[0008] In an optional embodiment, the switch is a knob, and a lever is fixedly provided on the circumference of the knob. The lever has an open position and a closed position. In the closed position, the switch is in a closed state, and in the open position, the switch is in an open state.

[0033] To make the purpose, technical solutions, and advantages of the embodiments of the present invention more clear, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the embodiments described are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without making creative efforts shall fall within the scope of protection of the present invention.

[0034] The following combination Figures 1 to 4 , describing the embodiments of the present utility model.

[0035] According to the embodiment of the present invention, a MCC cabinet is provided which is easy to configure. Figure 1 and Figure 2 , including a cabinet 100, which is equipped with multiple control boxes 101, and the control boxes 101 are equipped with circuit breakers corresponding to the controlled devices. The control box 101 is provided with a box door 1011, and the box door 1011 is provided with a switch 1012 for controlling the on and off of the corresponding circuit breaker. The box door 1011 is also provided with a blocking structure 200, and the blocking structure 200 has an unlocked state and a locked state. In the locked state, the blocking structure 200 prevents the switch 1012 from closing; the drawing cabin 300 is provided on the lower side of the corresponding control box, and the cabin body of the drawing cabin 300 is provided with a detection sensor electrically connected to the blocking structure 200, and the detection sensor is used to detect whether there are drawings placed in the drawing cabin 300, and when no drawings are detected, the detection sensor sends a signal to the blocking structure 200, and the blocking structure 200 is in a locked state when receiving the signal, and is in an unlocked state when no signal is received.

[0036] In this embodiment, a cabinet 100 is provided with multiple control boxes 101, which house circuit breakers for controlling equipment and enabling control of field devices. An on / off switch 1012 is installed on a door 1011 on the control box to facilitate switching the circuit breakers, thus fulfilling the MCC cabinet's functionality. A drawing compartment 300 is located beneath each control box 101 in the cabinet 100. This compartment 300 stores relevant drawings, such as wiring diagrams and site layout drawings, corresponding to the equipment controlled by the corresponding control box 101. Before inspecting field equipment, workers first power off the relevant equipment through the MCC cabinet, retrieve the relevant drawings, and then perform the inspection according to the drawings. During on-site construction, workers responsible for different equipment can retrieve the drawings related to their respective sections from different drawing compartments 300 and work simultaneously. A detection sensor within the drawing compartment 300 detects whether the drawings have been returned to the compartment 300. If the drawings have not been returned to the compartment 300, the switch 1012 is closed, preventing the corresponding equipment from being activated. This improves the management of drawings and prevents the loss or leakage of drawings.

[0037] Specifically, the above embodiments do not limit the specific form of the detection sensor. The detection sensor can be a contact sensor or a photoelectric sensor. In addition, it can also be an inductive card reader, which is used in conjunction with an inductive card set on the drawing book. Therefore, while detecting whether the drawings are placed in the drawing compartment 300, it can also avoid incorrect placement of drawings, and when the wrong drawings are placed, the staff can be reminded through the cooperation of other electronic devices such as buzzers and inductive card readers. The detection sensor can also be other types of sensors, as long as it can detect that the drawings are placed in the drawing compartment 300.

[0038] In addition, specifically, the above embodiment does not limit the specific form and volume of the drawing cabin 300, and it only needs to be able to accommodate corresponding drawings or related materials.

[0039] In one embodiment, the switch 1012 is a knob, and a lever 1013 is fixedly provided on the peripheral side of the knob. The lever 1013 has an open position and a closed position. In the closed position, the switch 1012 is in a closed state, and in the open position, the switch 1012 is in an open state.
