Abstract
The utility model relates to the technical field of the application of the electric power, in particular to an AC (alternating current) low-voltage draw-out electric-power reactive power compensation cabinet which comprises a cabinet body. The interior space of the cabinet body is divided by clapboards into a bus chamber, a main circuit breaker chamber, a plurality of capacitor chambers and secondary cable terminal connecting chambers. A drawable drawer-shaped subrack is arranged in each capacitor chamber. In the cabinet, a plurality of functional unit devices can be integrated in each drawer-shaped subrack, so that when a certain electric component is broken down and needs to be maintained, the broken-down electric component can be safely and conveniently replaced just after the subrack is pulled out, and the subrack is inserted into the cabinet after the replacement of the electric component, so that the operation is convenient and rapid; modularization can be adopted for manufacturing and processing the drawer-shaped subracks, so that the processing speed and the processing efficiency are high; when the electric components in the drawer-shaped subracks are replaced, the main switch is not needed to be cut off, so that the electricity utilization of the users and the power-supply quality are not affected.
Description
Technical field
The utility model relates to the electric power applied technical field, is specifically related to a kind of AC low-tension pull-out type electric reactive compensating cabinet.
Background technology
The AC low-tension electric reactive compensating cabinet that the existing power system uses, various electric elements all adopt fixed installation formula structure to be arranged in the compensating cabinet, when the electric elements damage needs maintenance, must cut off main switch, so can have influence on user power utilization and power supply quality; Be subjected to the restriction in space in the cabinet simultaneously, change time-consuming, the effort of electric elements, maintaining work is loaded down with trivial details.
The utility model content
The purpose of this utility model provides a kind of AC low-tension pull-out type electric reactive compensating cabinet, and its security reliability is strong, and functional module interchangeability is high and be easy to installation and maintenance.
For achieving the above object, the utility model has adopted following technical scheme: a kind of AC low-tension pull-out type electric reactive compensating cabinet, comprise cabinet, space in the described cabinet is separated into bus-bar room, main circuit breaker chamber, control room, electric capacity chamber and secondary cable terminal connections chamber by dividing plate, described electric capacity chamber is provided with several, and is provided with withdrawable drawer-like subrack in the electric capacity chamber.
Compared with prior art, advantage of the present utility model is:
(1), the utility model can be integrated in a plurality of functional unit devices in the drawer-like subrack, then when certain electric elements damage need be safeguarded, only subrack need be extracted out, just can change the electric elements that damage safely, easily, after finishing, replacing again subrack is inserted in the reactive power compensation cabinet, and easy to operate simple and direct;
(2), the drawer-like subrack can adopt the modularization production and processing, process velocity is fast and working (machining) efficiency is high;
(3), when changing the electric elements in the drawer-like subrack, need not cut off main switch, do not influence user power utilization and power supply quality.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the left view of Fig. 1.
