Abstract
The utility model discloses a jacket type DC circuit breaker, which belongs to the field of electrical and mechanical technology. The utility model mainly comprises a bottom plate, a porcelain vase, a knife blade, a back base, a baffle, a fixed splint and a movable splint. A spring is arranged respectively between the baffle and the fixed splint. An arc elastic sheet is arranged between the active splint and the back base. A jacket pipe is added and arranged on the spring. Because the spring and the arc elastic sheet are added and arranged on the utility model, the splint is of good elasticity. The sufficient contact between the knife blade and the splint is satisfied, which avoids the shedding phenomenon and is safe and reliable to be used. The jacket pipe can prevent the spring from being moistened and improve the service life.
Description
Technical field:
The utility model belongs to the mechanical ﹠ electrical technology field, is a kind of dc circuit breaker that is used on the electric gasifying railway.
Background technology:
Existing dc circuit breaker mainly is made up of porcelain vase, blade of knife switch, clamping plate, because the clamping plate poor flexibility, the clamping degree is undesirable, easily produces electric arc and obscission, causes short circuit, burns switch, the loss of power accident takes place.
Technology contents:
The technical problems to be solved in the utility model is to separate a kind of clamping plate to have good elasticity, and is safe and reliable, the dc circuit breaker that the life-span is long.
The method of the utility model technical solution problem is to install spring between baffle plate and clamping plate, and installing arc flexure strip is not drenched with rain in order to make elasticity between side clamping plate and rear base, is not subjected to humidity, adds on spring and installs protecting pipe additional.
The utility model makes clamping plate have better elastic owing to installed spring and arc spring sheet additional, has satisfied the clamping blade of knife switch and has fully contacted with clamping plate, does not produce the imagination that comes off, and safe and reliable, protecting pipe can prevent that spring from making moist, and improves useful life.
Description of drawings:
Fig. 1 is the utility model schematic diagram;
Fig. 2 is the utility model end view.
Embodiment:
The utility model mainly by base plate 1, porcelain vase 2, blade of knife switch 3, rear base 4, baffle plate 5, with decide clamping plate 6, ambulatory splint 7 is formed, between baffle plate 5 and strap 6, baffle plate 5 and ambulatory splint 7, install spring 8 respectively, installing arc flexure strip 9 between ambulatory splint 7 and the rear base 4.When blade of knife switch 3 enters between strap 6 and the ambulatory splint 7, because the elastic force of spring 8 tension force and arc flexure strip 9 can tightly be clamped blade of knife switch 3 fully contact.Joint pin 11 can be established in two ends at spring 8, joint pin 11 is separately fixed on baffle plate 5, strap 6 and the ambulatory splint 7, protecting pipe 10 is enclosed within on the joint pin 11, and protecting pipe 10 internal diameters are slightly larger than joint pin 11 external diameter protecting pipes 10 length less than distance between baffle plate 5 and the strap 6.Protecting pipe 10 can slide on joint pin 11, and is both moistureproof, do not influence strap 6 and ambulatory splint 7 actions again.
