Abstract
The utility model discloses a withdrawable armoured intermediate metal enclosed switchgear cabinet which is a 40.5 kV withdrawable armoured intermediate metal enclosed switchgear cabinet comprising a cabinet. The cabinet is provided with an instrument room, a circuit breaker room, a cable room, a bus room as well as an intermediate circuit breaker handcart. The circuit breaker room is arranged on the centre part of the switch gear cabinet. Moreover the inside of the cabinet is provided with two work guide cabinets in symmetrical arrangement which can enable the intermediate circuit breaker handcart to be sent from the testing location to the working location. The intermediate circuit breaker handcart can be slided fore-and-aft and linked between two work guides. The beneficial effects of the technology programme are that the intermediate circuit breaker handcart is adopted so that the arm of force of the handcart is short and the bearing capacity of electric power is strengthened. With high precision, reliable contact of static and dynamic contacts, the dynamo-thermal stability is excellent.
Description
Affiliated technical field
The utility model relates to switch cubicle, particularly relates to the armored withdraw type metal enclosed switch cabinet of 40.5kV middle.
Background technology
40.5kV the design that is console mode that the armored withdraw type ac metal closing switch gear uses in the market.Adopt the console mode design, then the circuit breaker cart size is big, and is highly high, the center of gravity height, therefore following disadvantage is in use often arranged: one, cooperate badly with switch cubicle, the big electrokinetic moment of the arm of force is big when the service position, the circuit breaker cart layback easily is pressed onto the people after the release, operate dangerous; Its two, the temperature rise of dynamic/static contact poor fit, contact is easily burnt.
The utility model content
In order to overcome the existing existing disadvantage of 40.5kV armored withdraw type metal enclosed switch cabinet, the utility model provides a kind of armored withdraw type metal enclosed switch cabinet of middle, it has not only avoided the disadvantage of console mode circuit breaker cart, and the arm of force is short, strengthened bearing electrodynamic ability, the precision height, the dynamic/static contact contact is reliable, and dynamic thermal stability is good.
The technical scheme that its technical problem that solves the utility model adopts is: the armored withdraw type metal enclosed switch cabinet of middle, it is the armored withdraw type metal enclosed switch cabinet of 40.5kV middle, comprise cabinet, this cabinet is provided with control room, breaker chamber, cable vault, bus-bar room and middle circuit breaker cart, and described breaker chamber is arranged at the switch cubicle front middle part; And be provided with two work that are symmetrical arranged and middle circuit breaker cart test position can be delivered to the service position in the cabinet and lead cabinet, the middle circuit breaker cart can be connected between the two work guide rails slidingly back and forth.
Also include earthed switch, this earthed switch is installed in the middle part of switch cubicle.
Described cabinet is for by multilayer bending of aluminizing zinc steel plate and the cabinet that adopts bolt to be spliced to form.
Be provided with in the described cabinet to projecting inward stupefied limit.
Be provided with opening horizontal concrete chute the preceding in the described work guide rail, the middle circuit breaker cart left and right sides is equipped with wheel, and above-mentioned wheel rollably is located in the above-mentioned horizontal concrete chute.
The horizontal concrete chute that described horizontal concrete chute runs through about being; Described wheel is an I shape, and it comprises that a scroll wheel, two that is fit to horizontal concrete chute is fixedly arranged on the spacer of scroll wheel left and right side respectively, and scroll wheel rollably is located in the horizontal concrete chute and two spacers are abutted against work guide rail left and right side respectively.
The beneficial effect of the technical program is:
One adopts the middle circuit breaker cart, and then the handcart arm of force is short, has strengthened bearing electrodynamic ability, the precision height, and the dynamic/static contact contact is reliable, and dynamic thermal stability is good;
Its two, the work guide rail matches with the middle circuit breaker cart, can pass through front and back, up and down, about spacing, make the stable and reliable operation of circuit breaker cart;
Its three, earthed switch is installed in the middle part of switch cubicle, then the length of operating axis has reduced about half, avoids the torsional deformation of earthed switch operating axis;
Its four, cabinet is the bolt splicing construction cabinet of high-quality aluminizing zinc steel plate multilayer bending, then mechanical strength is good;
Its five, the stupefied limit design of protrusion is arranged in the cabinet, then anti-internal arc fault ability is strong;
Its six, the horizontal concrete chute of work guide rail plays up and down position-limiting action to the middle circuit breaker cart, the adverse consequences that causes thereby the dynamic/static contact engagement that has been caused by electric power when effectively having avoided operation is not good, the dynamic/static contact engagement is effective; Two spacers are abutted against work guide rail left and right side respectively, prevent that the middle circuit breaker cart guide rail of working relatively from moving forward and backward, and prevent that the middle circuit breaker cart guide rail of working relatively from rocking.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
Fig. 1 is the organigram of switch cubicle of the present utility model.
Fig. 2 is the A-A generalized section of Fig. 1.
Fig. 3 is the D structure schematic diagram of the A-A place section of Fig. 1, (not expressing the middle circuit breaker cart).
Embodiment
40.5kV the armored withdraw type metal enclosed switch cabinet of middle as shown in Figure 1, 2, 3, comprises cabinet 1, this cabinet 1 adopts bolt to be spliced to form after by the bending of aluminizing zinc steel plate multilayer.In cabinet, be provided with to projecting inward stupefied limit in order to strengthen anti-internal arc fault ability.
Be provided with control room 2, breaker chamber 3, cable vault 4, bus-bar room 5 and middle circuit breaker cart 6 in the cabinet 1; The breaker chamber 3 outer valve 9 that are provided with.In the technical program, breaker chamber 3 is arranged at switch cabinet body 1 front middle part, and the earthed switch 7 of switch cubicle also is installed in the middle part of switch cabinet body 1.For safety, circuit breaker are only when disconnection or test position, just circuit breaker can carry out feed motion; Have only earthed switch to be in gate-dividing state, circuit breaker could move to the service position from disconnection or test position.
Being provided with two symmetrically arranged work on cabinet 1 leads cabinet 8 in addition, and middle circuit breaker cart 6 can be connected between the two work guide rails 7 slidingly back and forth; The cooperation of leading cabinet 8 by middle circuit breaker cart 6 and work can make middle circuit breaker cart 6 front and back in breaker chamber 3 slide, and also is to make middle circuit breaker cart 6 move between service position and disconnection or test position.Be provided with opening horizontal concrete chute the preceding, the horizontal concrete chute that it runs through about being in the work guide rail 8.Middle circuit breaker cart 6 left and right sides are equipped with wheel; This wheel is an I shape, and it comprises that a scroll wheel, two that is fit to horizontal concrete chute is fixedly arranged on the spacer of scroll wheel left and right side respectively, and scroll wheel thickness equals horizontal concrete chute thickness; But be located in the horizontal concrete chute, and two spacers are abutted against work guide rail left and right side respectively above-mentioned scroll wheel scroll forward and backward.
