Description
Technical Field
The utility model relates to an operating device of electric power supply facility, especially a control mechanism of cubical switchboard circuit breaker.
Background
In the electric power supply engineering at present, ZN98 type circuit breakers are mostly adopted in old type switch cabinets, and VS1 type circuit breakers which are advanced and relatively low in price are used in novel switch cabinets, so when the ZN98 type circuit breakers in old type switch cabinets need to be replaced in maintenance, the best scheme is to replace the circuit breakers into VS1 type circuit breakers. However, the center distance of the side output crank arm of the control mechanism of the ZN98 type circuit breaker is 230mm, while the center distance of the side output crank arm of the control mechanism of the VS1 type circuit breaker is 275mm, so that the VS1 type circuit breaker cannot be installed and replaced in an old type switch cabinet.
Disclosure of Invention
In order to overcome the problem that current VS1 type circuit breaker can not install and change to old type cubical switchboard in, the utility model aims at providing a control mechanism of modified cubical switchboard circuit breaker can overcome prior art's defect.
The utility model provides a technical scheme that its technical problem adopted is: the utility model provides a control mechanism of cubical switchboard circuit breaker, including the circuit breaker main shaft and with left main shaft support, right main shaft support, middle output connecting lever mechanism, left side output connecting lever mechanism, right side output connecting lever mechanism, middle oil buffer, left side oil buffer that the cooperation of circuit breaker main shaft is connected, left side main shaft support and right main shaft support install respectively on the circuit breaker frame, and respectively the cooperation connect in the left and right side tip of circuit breaker main shaft, characterized by: the left side oil buffer moves outward and installs and be close to left side main shaft support on the circuit breaker main shaft, left side output connecting lever mechanism moves inward and installs left side oil buffer with between the middle oil buffer on the circuit breaker main shaft, right side output connecting lever moves inward and installs on the circuit breaker main shaft, makes middle output connecting lever mechanism respectively with the central distance between left side output connecting lever mechanism and the right side output connecting lever mechanism is 230 mm.
According to the technical scheme, the outer sides of the left side output crank arm mechanism and the right side output crank arm mechanism can be additionally provided with the crank arm rotating shaft support so as to avoid that after the left side output crank arm mechanism and the right side output crank arm mechanism are moved inwards, the crank arm rotating shaft needs to be respectively extended to the left main shaft support and the right main shaft support for supporting.
According to the technical scheme, the return spring hanging plate on the right side output crank arm mechanism can be a curved ruler-shaped hanging plate so as to avoid interference between the return spring hanging plate and a right energy storage spring on the circuit breaker.
The beneficial effects of the utility model are that: because with VS1 type circuit breaker on the left side hydraulic buffer moves outward and installs and is close to left side main shaft support on the circuit breaker main shaft, left side output connecting lever mechanism moves inward and installs left side hydraulic buffer with between the middle hydraulic buffer on the circuit breaker main shaft, right side output connecting lever moves inward and installs on the circuit breaker main shaft, makes middle output connecting lever mechanism respectively with the central distance between left side output connecting lever mechanism and the right side output connecting lever mechanism is 230mm, so make VS1 type circuit breaker can install and change to use in the old-fashioned cubical switchboard to effectively improve the performance of circuit breaker and reduce the replacement cost.
The invention is further described with reference to the following figures and examples.

Fig. 1 is a schematic diagram of an embodiment of the present invention.
Fig. 2 is a schematic sectional view a-a of fig. 1.
In the figure: 1. a circuit breaker main shaft; 2. a left spindle support; 3. a right spindle support; 4. a middle output crank arm mechanism; 5. a left output crank arm mechanism; 6. a right output crank arm mechanism; 7. an intermediate hydraulic buffer; 8. a left side hydraulic buffer; 9. a circuit breaker frame; 10. a crank arm rotating shaft left support; 11. a crank arm rotating shaft right support; 12. a crank arm rotating shaft; 13. a return spring hanging plate; 14. a crank arm; 15. and a driving end.
Detailed Description
Referring to fig. 1-2, this control mechanism of cubical switchboard circuit breaker, including circuit breaker main shaft 1 and with left main shaft support 2, right main shaft support 3, middle output crank arm mechanism 4, left side output crank arm mechanism 5, right side output crank arm mechanism 6, middle hydraulic buffer 7, left side hydraulic buffer 8 that 1 cooperation of circuit breaker main shaft is connected, left side main shaft support 2 and right main shaft support 3 respectively the installation fix on circuit breaker frame 9, and cooperate respectively in the left and right side tip of circuit breaker main shaft 1, characterized by: left side hydraulic buffer 8 moves outward and installs and is close to left side main shaft support 2 on the circuit breaker main shaft 1, left side output crank arm mechanism 5 moves inward and installs left side hydraulic buffer 8 with between the middle hydraulic buffer 7 on the circuit breaker main shaft 1, right side output crank arm 6 moves inward and installs on the circuit breaker main shaft 1, make middle output crank arm mechanism 4 respectively with central distance between left side output crank arm mechanism 5 and the right side output crank arm mechanism 6 is 230 mm.
In addition, a crank arm rotating shaft left support 10 is additionally arranged on the outer side of the left output crank arm mechanism 5, so that the crank arm rotating shaft of the left output crank arm mechanism needs to be extended to the left spindle support 2 for supporting after the left output crank arm mechanism moves inwards; and a right crank arm rotating shaft right support 11 is additionally arranged on the outer side of the right output crank arm mechanism so as to avoid that the crank arm rotating shaft 12 of the right output crank arm mechanism needs to be extended to the right main shaft support 3 for supporting after the right output crank arm mechanism is moved inwards.
The return spring hanging plate 13 of the right output crank arm mechanism 6 is a curved-ruler-shaped hanging plate so as to avoid the interference between the return spring hanging plate 13 and a right energy storage spring (not shown) on the circuit breaker.
