Abstract
The utility model discloses a12kV armor-mounted air-insulated metal-enclosed switchgear. A cabinet body comprises a circuit breaker chamber, a bus chamber, a cable terminal chamber and a low-voltage chamber, the side part of the cabinet body is also provided with a valve drive mechanism, a circuit breaker trolley and a grounding switch locking mechanism, and the whole cabinet body is 600mm wide. Compared with the cabinet body with the width of 650mm in the prior art, the size of the cabinet body is reduced, the required area occupied by the substation can be reduced, and thus the total investment can be minimized. Meanwhile, the main switch applied in the switchgear adopts vacuum circuit breakers with the spacing of 150mm and can be matched with the majority of vacuum circuit breakers with the spacing of 150mm on the market. Moreover, the switchgear has a perfect five-stage anti-coupling lock and also has the same performance as that of the cabinet body with the width of 650mm.
Description
Technical field
The utility model relates to field of electrical equipment, relates to a kind of 12kV armored air insulation metal enclosed switchgear in particular.
Background technology
12kV armored withdraw type ac metal closing switch gear (claiming switch cubicle again) is the indoor complete controller switching equipment that uses in three-phase alternating current, 50Hz, single busbar connection or the sectionalized single busbar connection system; It has controls, protects and function such as monitoring circuit, can be used as in power industry or other industrial and mining enterprises, public utilities, skyscraper, power plant, electric substation, the power distribution station as the usefulness that receives electricity, distribution, feed or high-tension motor starting control.
The 12kV armored air insulation switch cubicle primary structure of joining vacuum circuit-breaker at present on the market has breaker chamber, bus-bar room, CTC cable terminating cubicle and low-pressure chamber, and the product that has also has pressure release passage, and this vacuum breaker is located in the breaker chamber.Wide two kinds of 650mm and the 550mm that are generally of the chest of the switch cubicle of 1250A-31.5kA among the existing 12kV; Wherein width is that the switch cubicle of 650mm is joined the standard specification fixed sealing type circuit breaker that spaced apart is 150mm; What width was that the switch cubicle of 550mm adopts then is primary circuit open type circuit breaker, and the latter compares poor-performing with the former.Because the fixed sealing type circuit breaker all adopts identical standard specification; Its pole width and handcart size all are standard specification; Thereby define the switch cubicle width; Therefore the switch cubicle width of the 12kV of existing employing fixed sealing type circuit breaker is 650mm, and wherein valve driving mechanism width is 80mm, and circuit breaker dolly and earthed switch blocking mechanism width are 64mm.But in real operation; Because place restriction; Width requirement to switch cubicle is narrower, and like the product with the 550mm specification, the dustproof and anti-corrosion capability of its circuit breaker is relatively poor again; The border influence that its performance is vulnerable to encircle on every side, and not enough with product width after several cabinets are arranged side by side of 650mm specification.
In view of this, the inventor has this case to produce to the above-mentioned defective further investigation of switch cubicle in the prior art when Design of length then.
The utility model content
The purpose of the utility model is to provide a kind of 12kV armored air insulation metal enclosed switchgear, its can be dustproof at blind foot and the prerequisite of anti-corrosion capability under, the concrete little characteristics of volume.
In order to reach above-mentioned purpose, the solution of the utility model is:
A kind of 12kV armored air insulation metal enclosed switchgear; Its cabinet comprises breaker chamber, bus-bar room, CTC cable terminating cubicle and low-pressure chamber; This cabinet sidepiece also is provided with valve driving mechanism, circuit breaker dolly and earthed switch blocking mechanism, and wherein, the integral width of this cabinet is 600mm.
Further, the width of this valve driving mechanism is 60mm, and the width of this circuit breaker dolly and earthed switch blocking mechanism then is 39mm.
Further, this circuit breaker dolly and the earthed switch blocking mechanism fixed axis that has connecting lever, latch plate and be used to control the latch plate stroke.
After adopting said structure, the width that the utility model relates to cabinet is 600mm, thereby is the 650mm cabinet with respect to width in the prior art, and its volume energy dwindles to some extent, thereby makes the floor space of required transformer station also minimum, and then overall investment is minimized; Its employed main switch of the utility model also is that spaced apart is the vacuum circuit-breaker of 150mm simultaneously; And can match with the vacuum circuit-breaker of most 150mm spaced apart on the market; And have five perfect anti-interlockings, the equal performance when promptly also having with 650mm cabinet width.

Embodiment
In order further to explain the technical scheme of the utility model, come the utility model is set forth in detail through specific embodiment below.
Extremely shown in Figure 4 like Fig. 1; A kind of 12kV armored air insulation metal enclosed switchgear that it relates to for the utility model; Its cabinet 100 comprises breaker chamber, bus-bar room, CTC cable terminating cubicle and low-pressure chamber, and the sidepiece of this cabinet 100 also is provided with valve driving mechanism 1, circuit breaker dolly and earthed switch blocking mechanism 2.
Because the vacuum circuit-breaker on the market is standard specification, therefore under the prerequisite that guarantees same performance, also can't dwindle with the size of the corresponding breaker chamber of vacuum circuit-breaker; Owing to consider that circuit cable will have certain insulating space, the width that therefore will dwindle switch cubicle can only be from the mechanical control section of both sides in addition.
Specifically extremely shown in Figure 4 like Fig. 2; The width of this valve driving mechanism 1 is reduced into 60mm by width 80mm of the prior art; Circuit breaker dolly and earthed switch blocking mechanism 2 width are reduced into 39mm by 64mm, and promptly this valve driving mechanism 1 has dwindled 20mm, and the circuit breaker dolly of a side and earthed switch blocking mechanism 2 have dwindled 15mm; Be whole cabinet 100 cocondensations little 50mm, promptly be reduced into the 600mm of the utility model by existing 650mm.Concrete, the roller 11 of this activity-driven mechanism respectively dwindles 20mm with axle 12 length, thereby makes a whole set of valve driving mechanism 1 width be reduced into 60mm by 80mm.
Connecting lever 21 radius of gyration of circuit breaker dolly and earthed switch blocking mechanism 2 (shown in Figure 4) change 14.5mm into by 38mm, reduce rotary space, have increased fixed axis 22 simultaneously, and the Stroke Control that makes latch plate 23 is in 39mm.Need to prove that for the width that makes cabinet 100 is 600mm, it also comprises other implementations, being not limited in above-mentioned is a kind of implementation of 60mm with activity-driven mechanism width adjustment.
In sum, the width that the utility model relates to cabinet 100 is 600mm, thereby is 650mm cabinet 100 with respect to width in the prior art, and its volume energy dwindles to some extent, thereby makes the floor space of required transformer station also minimum, and then overall investment is minimized; Its employed main switch of the utility model also is that spaced apart is the vacuum circuit-breaker of 150mm simultaneously; And can match with the vacuum circuit-breaker of most 150mm spaced apart on the market; And have five perfect anti-interlockings, the equal performance when promptly also having with 650mm cabinet 100 width.
Product form of the foregoing description and graphic and non-limiting the utility model and style, the those of ordinary skill of any affiliated technical field all should be regarded as not breaking away from the patent category of the utility model to its suitable variation or modification of doing.
