Embodiment
Below in conjunction with the accompanying drawing in the embodiment of the present invention, the technical scheme in the embodiment of the present invention is clearly and completely described, obviously, described embodiment is only the present invention's part embodiment, instead of whole embodiment.Based on the embodiment in the present invention, those of ordinary skill in the art, not making the every other embodiment obtaining under creative work prerequisite, belong to the scope of protection of the invention.
Referring to Fig. 1 a-1b, the embodiment of the invention discloses a kind of electric equipment power cabinet, with in meeting electric equipment power expanding demand, realize low cost and the centralized control of electric equipment, comprising:
(Fig. 1 a is the structural representation of single prime power cabinet 10 to multiple prime power cabinets 10 that are in parallel, Fig. 1 b is the structural representation that is parallel with the electric equipment power cabinet of 3 prime power cabinets 10), wherein, the net side power cabinet 12 that each prime power cabinet 10 comprises pusher side power cabinet 11 and is in parallel with pusher side power cabinet 11.
Easily understand and apply this product for ease of those skilled in the art, below in conjunction with existing electric equipment power expanding scheme, the technical scheme described in the present embodiment being described in detail.
For the existing electric equipment such as current transformer and frequency converter, its building block comprises power cabinet (comprising 1 pusher side power cabinet and 1 net side power cabinet), for controlling control cubicle and other essential building blocks of described power cabinet.Prior art is to meet the power expanding demand of described electric equipment under voltage levels more, multiple monomer electric equipments are directly in parallel, although such way can improve the integrally-built power grade after parallel connection, also has certain defect, specific as follows:
First, because each power cabinet in this overall structure is respectively to be controlled by different control cubicles, the operating state of each monomer electric equipment is independent of one another, cannot centralized control, and therefore large, the poor stability of this integrally-built control difficulty;
Secondly,, because this overall structure need to be introduced multiple monomer electric equipments simultaneously, therefore cost is too high.
For this reason, the prime power unit of the present embodiment using the pusher side power cabinet 11 that is in parallel and net side power cabinet 12 as electric equipment power cabinet, the power capacitance of described prime power unit equals the power capacitance of existing single electric equipment power cabinet; Staff only need be in an electric equipment multiple described prime poweies in parallel unit, can realize the power expanding of electric equipment, the power capacitance after dilatation is the power capacitance sum of each described prime power unit.
Because the present embodiment is only transformed the power cabinet of an electric equipment, simplicity of design, cost are low, and each described prime power unit, by the control cubicle centralized control in this electric equipment, is controlled difficulty and greatly reduced, thereby solve the problem that prior art exists; In addition, in the situation that dilatation degree is equal, the volume of the electric equipment obtaining based on the present embodiment reduces greatly compared to existing high voltage electric equipment (being the entirety that the direct parallel connection of multiple electric equipments obtains), and installing space, transport and assembling etc. to electric equipment all bring great convenience.
Wherein, for the disclosed electric equipment power cabinet of the present embodiment, between the pusher side power cabinet 11 of same prime power cabinet 10 and net side power cabinet 12, realize parallel connection, the preferred stack bus bar 13 of described the first electrical fitting by overlap joint the first electrical fitting.Concrete, stack bus bar 13 is a kind of high-power modular electrical fittings that can repeat the succinct feature such as quick of electric property, Low ESR, anti-interference, good reliability, saving space, assembling that have.Indulge and realized the circulation between pusher side power cabinet 11 and net side power cabinet 12 across the stack bus bar 13 of pusher side power cabinet 11 and net side power cabinet 12, change of current area is large, safe and reliable.Certainly, described the first electrical fitting also can adopt copper bar etc., does not limit to;
Wherein, every adjacent two prime power cabinets 10 are realized parallel connection by overlap the second electrical fitting between the first electrical fitting separately, and described the second electrical fitting can be selected copper bar 14 or stack bus bar etc., does not limit to.In addition; also can extension circuit protective device between the first electrical fitting 13 and the second electrical fitting 14; as fuse etc.; be to overlap the second electrical fitting 14 after adding fuse between adjacent two the first electrical fittings 13, to avoid the excessive even initiation fire or cause the expansion of accident of circuit burnout that causes of electric current.
