Description

A kind of miniaturization structure of KYN28 central switch cabinet
Technical field
This practicality relates to high-voltage switch gear technical field, relates in particular to a kind of intermediate switchgear cabinet.
Background technology
Intermediate switchgear cabinet, full name is metal armouring middle disposed withdrawn type switchgear.Belong to high voltage distribution installation, maximum operating voltage 3.6/7.2/12kV, is the indoor complete power distribution equipment of three-phase alternating current 50Hz sectionalized single busbar connection system or double-bus segmented system.For the network power of accepting and joining 3.6-12kV, and power circuit is carried out and controlled protection, monitoring and measuring.Its minute three-decker, upper strata is bus and control room (isolation mutually), and intermediate layer is breaker chamber, and lower floor is cable vault.Intermediate switchgear cabinet is mainly used in power plant, the power transmission of medium and small generator, electric power system secondary substation be subject to electricity, power transmission, the distribution of industrial and mineral enterprises and institutions, and the starting of Large-scale High-Pressure motor etc.
In the GB design of existing KYN28 central switch cabinet, it is high that cabinet is of a size of 2300() * 1500(is dark) * 800(is wide), size is not ideal enough, comprehensive automation protective device and secondary meter chamber binding post, higher than ordinary people's normal height operation height, bring larger difficulty to the aspects such as secondary connection and measurement, debugging; The copper bar outlet wiring hole height of cable vault is on the low side, installs to high voltage power cable wiring and brings certain difficulty.Because current transformer lateral dimension is large, side is arranged on switch cubicle rear portion, and the height dimension of switch cubicle is large, is unfavorable for the miniaturization of switch cubicle.In addition, the plate face of the cabinet door of KYN28 central switch cabinet is plane at present, and its third dimension shortcoming is not attractive in appearance.
Summary of the invention
The shortcoming that the utility model exists for above-mentioned KYN28 central switch cabinet, reduce the size of cabinet, reduce cable vault's wiring space height, dwindle the height of control room's secondary wiring terminals, shortened outlet contact box of circuit breaker to instrument transformer spacing, and cabinet door is improved, improve aesthetics.
The technical scheme that the technical problem that the present invention solves adopts is:
A kind of miniaturization structure of KYN28 central switch cabinet, the busbar chamber that comprises anterior control room, breaker chamber and cable vault and rear portion, control room, breaker chamber and cable vault are respectively equipped with cabinet door, it is characterized in that control room's height is 480mm, and the height of cable vault is 700mm.The utility model narrows down to 480mm original control room height from original 580mm, and original cable vault height is narrowed down to 700mm from original 840mm.The highest size height of cabinet size is compressed to 2060mm from original 2300mm, and solve cable vault's wiring space height problem, dwindle the height of control room's secondary wiring terminals, facilitate professional and technical personnel to carry out the technical problem of wiring, measurement, debugging, a kind of novel rational cabinet type is provided, had both facilitated secondary connection, saved again copper bar cost one time, also facilitate the installation wiring of power cable, realized the object of the miniaturization of KYN28 central switch cabinet and safe operation.
Because of cable vault's compression 140mm, make terminal connections place whole height decline 140mm, facilitated secondary connection and test, reduced technical staff's wiring and operation height, convenient debugging and detection.
During concrete enforcement, cabinet door both sides are provided with incline bench, and the incline bench of cabinet door forms trapezoid boss.On cabinet door, be provided with trapezoid boss, strengthened cabinet door third dimension, promoted the aesthetic property of whole cabinet.
During concrete enforcement, the inclination angle on inclined-plane, cabinet door both sides is 45 degree.At three cabinet doors, by pressing plate technique, fold 45 degree oblique angles, realize the rectangle third dimension of cabinet door, strengthened the aesthetic property of whole cabinet.
During concrete enforcement, the indoor current transformer that is provided with of busbar, busbar is indoor is provided with horizontal fixed head, and the base of current transformer is fixed on fixed head, on the side plate of busbar chamber, be fixed with one time fixed contact box, current transformer is connected with a fixed contact box by a busbar.The utility model is improved to original current transformer fixed position on horizontal fixed head at switch cubicle rear portion, change into current transformer be inverted fixing after, can shorten outlet contact box to a copper bar length between instrument transformer, saved cost; Current transformer changes into be inverted after installation, can be switch cubicle miniaturization transformation and reserves height space, is convenient to switch cubicle and reduces height, realizes switch cubicle miniaturization transformation.
The beneficial effects of the utility model are: the utility model has guaranteed the miniaturization of switch cubicle, facilitated secondary connection debugging and an outlet cable connection to install, cabinet door has become third dimension, also solved the irrational problem of the rearmounted installation of instrument transformer simultaneously, realize and be inverted fixed installation, facilitate wiring and maintenance, reduced cabinet aluminizing zine plate and steel plate materials used, shorten the length of copper bar, saved cost.
