Abstract
The utility model discloses a handcart for an FC loop high-voltage central-positioned aggregated switchgear. A handcart frame (7) is installed on a handcart chassis (1); a fuse insulating bush combining bracket (3) is fixed on the handcart frame (7); a major loop moving contact (2) is arranged at the front part of the fuse insulating bush combining bracket (3); a fuse holder (9) is installed inside the fuse insulating bush combining bracket (3); a contactor (6) is arranged between the fuse insulating bush combining bracket (3) and the handcart chassis (1); and the major loop moving contact (2), a fuse (5) and the contactor (6) are connected in one loop by a connecting bus (8). In the utility model, the miniaturization of the FC loop high-voltage central-positioned aggregated switchgear is realized; the fuse insulating bush combining bracket (3) is adopted, and the insulating property of the fuse (5) and the fuse holder (9) is strong, so that the contactors (6) of various types and specifications can be fitted, the universality is good, and the width of the FC loop high-voltage central-positioned aggregated switchgear can reach 600mm.
Description
Technical field
The utility model relates to a kind of switch cabinet handcart, and particularly a kind of FC loop high pressure middle voltage switchgear handcart belongs to the switchgear assembly technical field.
Background technology
The major loop that fuse (F) and contactor (C) are formed in the present high pressure middle voltage switchgear; be FC loop (address of switch major loop electrical equipment); relatively middle circuit breaker loop (address of switch major loop electrical equipment) have volume little, save the bus material; because of the contactor price far below the circuit breaker price; and fuse short-circuit protection performance is better than circuit breaker, and contactor is fit to frequent operation again.So in the occasion of frequent deciliter normal current, as the crane of the frequent lifting of port and pier control, the cost performance of FC loop high pressure middle voltage switchgear is far superior to high pressure middle circuit breaker loop voltage switchgear.Because of the miniaturization of FC loop high pressure middle voltage switchgear is its important characteristic.Make the high pressure middle voltage switchgear miniaturization of FC loop, FC loop middle handcart is crucial, has only accomplished the miniaturization of FC loop middle handcart, just may accomplish the miniaturization of FC loop middle voltage switchgear.Domestic existing FC loop high pressure middle voltage switchgear width is generally all greater than 600mm.
The utility model content
The purpose of this utility model provides a kind of miniaturization FC loop high pressure middle voltage switchgear handcart, and the good insulation preformance after fuse and fuse base are installed on the middle handcart is fit to be equipped with all kinds of contactors, in use has good security performance.
For realizing above-mentioned technical purpose, the technical solution of the utility model is: a kind of FC loop high pressure middle voltage switchgear handcart, comprise the major loop moving contact, fuse insulating case sectional shelf-unit, fuse, contactor, fuse base, handcart chassis and handcart frame, the handcart frame is installed on the handcart chassis, fuse insulating case sectional shelf-unit is fixed on the handcart frame, the major loop moving contact is arranged on fuse insulating case sectional shelf-unit front portion by upper-lower position, fuse base is fixedly mounted in the fuse insulating case sectional shelf-unit, contactor is arranged between fuse insulating case sectional shelf-unit and the handcart chassis, the major loop moving contact, fuse, contactor is connected in the loop by connection bus.
The utility model has solved the miniaturization issues of FC loop high pressure middle voltage switchgear handcart, has promptly accomplished the miniaturization of FC loop high pressure middle voltage switchgear; Because fuse insulating case sectional shelf-unit is housed, copper busbar connects simple and convenient, can save the very expensive copper busbar material of present price, good insulation preformance after fuse and fuse base are installed, thereby strengthened FC loop high pressure middle voltage switchgear security performance, simultaneously can be equipped with various types of contactors, highly versatile easily again; It is simple and convenient to change fuse 5, and makes the miniaturization more of FC loop high pressure middle voltage switchgear, and its width only is 600mm.
Description of drawings
Below in conjunction with the drawings and specific embodiments the utility model is described in further detail.
Accompanying drawing is a structural representation of the present utility model.
Embodiment
As shown in drawings, the utility model is mainly by handcart chassis 1, major loop moving contact 2, fuse insulating case sectional shelf-unit 3, control loop connector 4, fuse 5, contactor 6, fuse base 9, handcart frame 7, connection bus 8 compositions such as grade.Adopt fuse insulating case sectional shelf-unit 3, connection bus 8 is installed easily, can be easily the contactor 6 of fuse 5 and various models be connected in the loop, and it is also extremely convenient to change fuse 5, as long as be inserted into or extract fuse base 9.
FC of the present utility model loop high pressure middle voltage switchgear handcart has width smaller, in the wide FC loop high pressure middle voltage switchgear of the 600mm that can pack into (600mm is wide to be the less FC loop high pressure middle voltage switchgear of present state insied width).Because fuse insulating case sectional shelf-unit 3 is housed, connection bus 8 is installed simple and convenient, can save the very expensive copper busbar material of present price, good insulation preformance after fuse 5 and fuse base 9 are installed, thereby strengthened the security performance of FC loop high pressure middle voltage switchgear, simultaneously can be equipped with various types of contactors, highly versatile easily again; It is simple and convenient to change fuse 5.
The foregoing description limits the utility model never in any form, and every employing is equal to replaces or technical scheme that the mode of equivalent transformation obtains all drops in the protection range of the present utility model.
