Abstract
The invention relates to a low-voltage fixed type switchgear which comprises a cabinet body, wherein a meter relay room and a three-phase busbar room are arranged at the upper part of the cabinet body; a rotary knife switch is arranged at the lower part of the three-phase busbar room; a vertical bus is connected with a circuit breaker through a connection bar; the circuit breaker is mounted on a mounting board which is mounted on a cross beam; a current transformer is arranged at the lower part of the cross beam; and a horizontal bus is arranged at the lower part of the current transformer, and a zero bus is arranged at the lower part of the cabinet body. The switchgear has the advantages of simple structure, reliability in operation, and convenience in routine maintenance.
Description
Technical field
The present invention relates to a kind of switchgear assembly, be specifically related to a kind of low-voltage complete switch equipment.
Background technology
Low-voltage complete switch equipment is by switch cubicle manufacturing firm a plurality of low tension switches organically to be connected with devices such as the control of being correlated with, measurement, protections; With a kind of assembly that structure member intactly fits together, the shortcoming that present low-voltage complete switch equipment structurally exists is: mostly the basic framework material is channel-section steel or cold-rolled steel sheet, leans on bolt to the sled splicing; Framework is loose; Rigidity is not enough, and overall dimension is unstable, uses perishable for a long time; Degree of protection is IP3X, is not suitable in the moist environment of many dirt; The main bus bar system is rear-mounted, and is exposed copper bar, does not have sealing, and causing can only front-operated, as carrying out operation maintenance behind the cabinet by force, because of getting into charging zone, is prone to cause personal injury; General nothing is isolated between each functional compartments, is prone to the mistakenly entering into charged zone during operation, and accident is prone to spread.Aggregate erection mode and outlet scheme are single, are difficult to satisfy user's demands of different.
Summary of the invention
Goal of the invention: the objective of the invention is provides a kind of simple in structure, reliable in order to overcome deficiency of the prior art, and regular maintenance is the low pressure draw out switchgear easily.
Technical scheme: in order to solve the problems of the technologies described above, the fixed switchgear of low pressure of the present invention, it comprises cabinet; Be provided with instrument relay chamber and three-phase bus chamber on said cabinet top, be provided with the rotating knife switch in bottom, said three-phase bus chamber, upright bus links to each other with circuit breaker through connecting row; Said circuit breaker is installed on the mounting panel on the crossbeam; Be provided with current transformer in said crossbeam bottom, be provided with horizontal bus, be provided with zero bus in said cabinet bottom in said current transformer bottom.
Be provided with rotary handle at said cabinet middle part.
Be provided with ammeter and voltmeter on said cabinet panel top.
Said cabinet bottom is a louvered panel.
On said cabinet panel, also be provided with direction board.
The present invention is the metal-enclosed type structure, and cabinet is assembled through the part of high precision numerical control apparatus processing by shaped steel and high-quality cold-rolled steel, and dividing plate is arranged between cabinet, can prevent the expansion of horizontal accident.
Main bus bar of the present invention places the cabinet top, and the bus-bar room top is all opened wide after opening top cover, is convenient to installation and maintenance, and integral device has complete ground protection circuit.
Beneficial effect: the present invention compared with prior art, its remarkable advantage is: internal arrangement of the present invention is reasonable, and is reliable, and general safety is reliable, regular maintenance is convenient.
