Description

Low voltage drawer switchgear

technical field

The utility model relates to a low-voltage drawer type switchgear, which is mainly used in power distribution systems of industrial and mining enterprises such as land use and power stations, and belongs to the field of electric equipment manufacturing.

Background technique

The layout of the low-voltage drawer-type switchgear currently in use is unreasonable, neither can it meet the combination of various structural forms, nor can it realize the replacement of functional units of the same specification; secondly, it is difficult to overhaul and lack sufficient safety guarantees and safety measures. It is conducive to the safe operation and quick maintenance of the equipment, and the operability is not satisfactory.

Contents of the invention

Design purpose: to avoid the deficiencies in the background technology. Design a low-voltage drawer-type switch cabinet with strong versatility, easy combination, convenient maintenance and strong operability.

Design scheme: In order to achieve the above design purpose. 1. The design of two sets of main busbars built into the horizontal busbar compartment in the cabinet is one of the design features of the utility model. The purpose of doing this is: it can supply power either independently or in parallel, providing users with various needs. 2. The design that the electrical appliance compartment and the busbar compartment are connected by plug-ins is the second feature of the design of the utility model. The purpose of doing like this is: it is not only convenient for rapid assembly, but also convenient for maintenance, and more importantly, it improves the safety of operation. 3. The design that the function board is located between the busbar room and the cable room is the third feature of the design of the utility model. The purpose of doing this is to effectively prevent accidents caused by flashover and short circuit between busbars caused by faults of switching elements. 4, the structure of switchgear body is bent into the design that C-shaped profile assembly is formed by the steel plate that is modulus hole with 25mm, is four of the feature of the utility model design. The purpose of doing this is: it can meet the combination of various structural forms, and conforms to the feature of high versatility of the switchgear. 5. The vertical busbar in the busbar compartment is designed as a right-angled copper busbar, which is the fifth feature of the utility model design. The purpose of doing this is: after being embedded in the functional board, it can prevent the flashover of the vertical busbar and can withstand the electromotive force generated by the short-circuit current. 6. There are drawers in a plurality of functional unit compartments and the design separated by galvanized metal base plates with ventilation holes between the upper and lower drawers is six of the design features of the present utility model. The purpose of doing this is to increase the interchangeability of functional units of the same specification, and at the same time make the insulation protection between adjacent circuits play a role. 7. The switch cabinet is mixed with PC cabinet and MCC cabinet in the same cabinet to form a single-sided and double-sided operation cabinet design, which is the seventh feature of the utility model design. The purpose of doing this is to make the product more flexible and form different operation cabinets to meet the different needs of users.

Technical solution: low-voltage drawer switchgear, which includes a cabinet body, the horizontal bus compartment is located at the rear of the cabinet body, the electrical compartment is located at the front left of the cabinet body, the cable compartment is located at the front right side of the cabinet body, and the control circuit is located at the upper part of the cabinet body.

Compared with the background technology, the utility model has strong versatility, is convenient for quick assembly and convenient maintenance; secondly, it is safe and reliable, and can perform interchange of functional units of the same specification.

Detailed ways

Embodiment 1: with reference to accompanying drawing 1 and 2. Low-voltage drawer-type switchgear, which includes a cabinet body 6, a horizontal bus compartment 1 is located at the rear of the cabinet body 6, and the upper and lower sides of the horizontal bus compartment 1 are respectively equipped with main buses, and the electrical compartment 4 and the horizontal bus compartment 1 are connected through plug-ins. The electrical compartment of the horizontal busbar compartment 1 is equipped with a high-density polyurethane plastic functional board 2 . Electrical appliance compartment 4 is positioned at cabinet body 6 front left sides, and electrical appliance compartment 4 is made of a plurality of drawers, and the galvanized metal bottom plate that ventilation hole is arranged between upper and lower drawer separates. The cable compartment 5 is located on the front right side of the cabinet 6, and the control circuit 3 is located on the upper part of the cabinet. The structure of the switch cabinet body 6 is composed of C-shaped profiles bent from 25mm steel plates with modulus holes, which meets the combination of various structural forms. There are drawer units 6 in the compartments of the functional units and there are belts between the upper and lower drawers. The galvanized metal floors of the ventilation holes are separated, so as to ensure that the functional units can be assembled and disassembled as a whole to meet the characteristics of interchangeability of the same specification, and also provide a certain degree of insulation protection between adjacent circuits.

Embodiment 2: On the basis of Embodiment 1, various drawer units can be assembled individually or mixed in the same cabinet.

It should be understood that: although the above-mentioned embodiments have described the utility model in more detail, these text descriptions are only simple text descriptions of the design ideas of the utility model, rather than restrictions on the design ideas of the utility model. The combination, addition or modification of the design idea of the utility model all fall within the protection scope of the utility model.
