Further, described major loop structure is that conductive component (upper wire outlet seat, lower wire outlet seat, vacuum interrupter etc.) is longitudinally installed in pole and forms full-closed structure, and described pole is to adopt APG(automatic pressure gel by epoxy resin) technique builds the pole forming.Described operating mechanism comprises energy-storage units, combined floodgate unit and separating brake unit.On described guidance panel, be provided with switch knob, opening button, stored energy operation device and indicating device, switch knob closes a floodgate in order to control combined floodgate unit, opening button is in order to control separating brake unit separating brake, stored energy operation device can be both the energy accumulation handle in order to manual energy storage, also can be the energy storage device completing by motor, indicating device comprises counter, energy storage state indication and the indication of separating brake/combined floodgate.
Further, described energy-storage units is spring energy agency.
Indoor AC of the present utility model adopts such scheme, by fully closed major loop structure and modular operation mechanism, has the following advantages:
1, by the bottom at circuit breaker case, shockproof base plate is set, makes this circuit breaker there is Shockproof damping function, strengthen the useful life of whole circuit breaker;
2, operating mechanism adopts modularized design, forms one with vacuum switch body, possesses reliable, perfect machinery and electric anti-error chain function, has guaranteed the fail safe of operation and maintenance;
3, before and after major loop structure and operating mechanism, arrange, form a monolithic devices layout, can make like this operating characteristics and the arc control device folding desired properties of operating mechanism more identical, reduce unnecessary intermediate transmission link, energy consumption and noise have been reduced, electric and mechanical chain, is that its operating characteristics is more reliable reliably;
4, major loop adopts full-enclosed structure, the parts of major loop are longitudinally arranged on by epoxy resin and adopt APG technique to pour into a mould on the pole forming, there is good resistance to electric arc, anti-aging, high-strength characteristic, can effectively prevent external impacts, the impact of the external factor such as filthy environment on it, has increased galvanic circle body simultaneously and has born ability moving, heat-stable current;
5, the energy-storage units in operating mechanism is spring energy agency, adopt modularized design, simple and reasonable for structure, there is higher mechanical strength and rigidity, thereby guaranteed the stable mechanical performance, reliable of vacuum switch;
6, this indoor AC can be used as fixed installation unit, and also can adapted special-purpose propulsive mechanism, forms handcart unit and use.
Accompanying drawing explanation
Fig. 1 is the profile schematic diagram of the circuit breaker case of embodiment of the present utility model.
Embodiment
Now with embodiment, the utility model is further illustrated by reference to the accompanying drawings.
As a specific embodiment, as shown in Figure 1, a kind of indoor AC 100 of the present utility model, comprise circuit breaker case 101, and the major loop structure being fixedly connected with circuit breaker case 101 and operating mechanism (not shown on figure), before and after this major loop structure and operating mechanism, arrange the degree of reliability with strengthen operation performance.On described circuit breaker case 101, be provided with guidance panel, by this guidance panel, operating mechanism controlled.Described circuit breaker case 101 bottoms are provided with chassis vehicle 103, are also provided with shockproof base plate 102 between described circuit breaker case 101 and chassis vehicle 103.Wherein, described shockproof base plate 102 is the shockproof base plates of rubber, in addition for good heat radiation, also offers through hole, to strengthen ventilation and heat on described shockproof base plate 102.
