Embodiment
As Fig. 1~shown in Figure 5, energy storage type high sublevel miniature circuit breaker, comprise the base 6 that handle 9 is housed, base 6 is provided with binding post 3 and arc-extinguish chamber 2, arc-extinguish chamber 2 one sides are provided with striking chip module 21 lower-left sides the buckle 1 of installation, handle 9 is connected with tripping 14 by U-shaped connecting rod 10, and joins by tripping 14 and snap close 11, and tripping 14 is enclosed within on the small column 13.1 of support 13; Moving contact component 18 left sides are provided with electromagnetic system 5, it is characterized in that: moving contact component 18 is enclosed within on the fixed axis 17, also be provided with a spring support assembly 15 between moving contact component 18 and the support 13, support 13 is installed on the pillar of base 6, connect an extension spring 8 on the support 13, the other end of extension spring 8 is connected with fixedly pillar 6.1 on the base 6; Pillar lower plane at base 6 is provided with energy storage connector 16, and torsion spring 7 is housed on the energy storage connector 16, and wherein a leg of torsion spring 7 withstands on the groove of base 6, and an other leg hangs over below energy storage connector 16 projections; Run-on tab assembly 21 is provided with striking sheet, brace and bimetal leaf 20 and is flexible coupling, and bimetal leaf 20 and dropout pull bar 19 join, and dropout pull bar 19 also is connected with snap close 11.
During enforcement, the opening of arc-extinguish chamber 2 is to assemble by 23 of a plurality of arc-chutes are interlaced with each other.
During use, during handle 9 clockwise direction rotation under external force, when the fulcrum of handle 9 on base 6 rotates, drive U-shaped connecting rod 10 action to the right, U-shaped connecting rod 10 promotes tripping 14 fulcrum clockwise direction on support 13 and rotates, when tripping 14 with after snap close 11 contacts, snap close 11 12 clockwise directions around the shaft rotates, support 13 compression spring support assemblies 15 meanwhile moving contact component 18 center on rotating shaft campaign 17, under tripping 14 promotes and under the tension of extension spring 8,12 clockwise directions rotate around the shaft.When handle 9 turns to certain angle, energy storage connector 16 is with after boss below the moving contact seat contacts, lower end, support 13 right side is protruded the position and is close to energy storage connector 16, when driving handle 9 continues the clockwise direction rotation, the pillar clockwise direction of energy storage connector 16 on base 6 rotates, thereby drive energy storage connector 16, continue driving handle 9, energy storage connector 16 continues clockwise direction and rotates, when handle 9 under external force clockwise direction turn to energy storage connector 16 when terminal, the position is protruded can't touch energy storage and connect the time in support 13 lower ends, support 13 is followed 12 clockwise direction quick rotation around the shaft under tripping 14 and extension spring 8 act on, reach the purpose with the fixed contact quick-make.When circuit breaker extreme overload occurs at work, bimetal leaf 20 on the leader board component 21 is crooked to the right, bimetal leaf 20 is by dropout pull bar 19 pulling snap closes 11, snap close 11 and tripping 14 releases, support 13 12 produces plane motion around the shaft under extension spring 8 tension, moving contact component 18 also produces counter-force down with the effect of knowing stage clip, separates rapidly with fixed contact assembly 5.The electric arc that produces when moving contact component 18 and fixed contact assembly 5 closures or disconnection enters arc-extinguish chamber 2 through the guiding of striking sheet and extinguishes.Regulate the requirement that adjustment screw 22 reaches circuit breaker relevant action characteristic in addition.After snap close 11 releases, handle 9 is untied support 13 lower ends to touching the active force of energy connector 16 in the action of reset spring turning down, and torsion spring 8 can all be got back to initial position by connector 16 with touching.
