Abstract
The utility model relates to a high-voltage vacuum circuit breaker with a self operational power supply and mainly aims at solving the problem that the existing high-voltage vacuum circuit breaker does not possess a self power supply and results in operation troubles. The high voltage vacuum circuit breaker with the self operational power supply comprises a housing, wherein an incoming wiring terminal and an outgoing wiring terminal are arranged at the upper end of the housing; an operation box is arranged at the outer side of the housing; a motor which drives a circuit to be switched on or off is arranged in the operation box; a voltage transformer is arranged in the housing; the incoming wiring terminal is electrically connected with the voltage transformer; and the voltage transformer is electrically connected with the motor. By adopting the scheme of mounting the voltage transformer in the vacuum circuit breaker to achieve the purpose of providing automatic power supply to an operating mechanism, the effect of the self power supply is realized with no need of additionally mounting a power supply facility, and the operation is simple; and thus, the using efficacy of the circuit breaker is effectively improved.
Description
Technical field
The utility model relates to a kind of circuit breaker, refers in particular to a kind of high-pressure vacuum breaker that carries operating power.
Background technology
Vacuum circuit-breaker is used comparatively universal in power distribution network, can be used as control and protection high voltage electric equipment usefulness.It has volume little, in light weight, be applicable to the advantage that frequent operation, arc extinguishing need not overhaul, and can supply in industrial and mining enterprises, power plant, the transformer station usefulness as the protection and the control of electric equipment.Existing vacuum circuit-breaker does not have self-powered function; All outer power supplys of action beyond some itself are supplied and are realized, realize closing a floodgate or separating brake as needing in the circuit breaker operation mechanism rotate through motor, and motor need be supplied its power supply and could realize moving; So; Reach the purpose of its power supply of supply, need to install in addition power transmission facility, this brings operation inconvenience to operation.
Summary of the invention
In order to overcome deficiency and the defective in the background technology, the utility model provides a kind of high-pressure vacuum breaker that carries operating power, solves the existing high-pressure vacuum breaker that carries operating power and has the problem that can not self-poweredly cause troublesome poeration.
The technical scheme of the utility model is: a kind of high-pressure vacuum breaker that carries operating power; Comprise housing, said housing upper end is provided with inlet wire binding post and outlet binding post, and described hull outside is provided with control box; Be provided with the motor that drives circuit combined floodgate or separating brake in the said control box; Be provided with voltage transformer in the said housing, said inlet wire binding post is electrically connected with voltage transformer, and said voltage transformer is connected with motor and for it power supply is provided.
Also comprise control cabinet, be provided with the controller that is electrically connected through connector with control box in the said control cabinet.
Said controller is a relay protector.
Said connector is cable or plug connector.
Said voltage transformer is electrically connected with controller.
Compared with prior art; The utlity model has following beneficial effect: be employed in voltage transformer is installed in the vacuum circuit-breaker; To operating mechanism the purpose of automatic power is provided, thereby realizes self-powered effect, need not to install in addition power supply facilities; Simple to operate, make that the use effect of this circuit breaker is effectively improved.
Description of drawings
Fig. 1 is the structural representation of the utility model.
Among the figure, housing 1, inlet wire binding post 2, outlet binding post 3, control box 4, voltage transformer 5, control cabinet 6, connector 7.
Embodiment
Be described further to the embodiment of accompanying drawing below the utility model:
Shown in figure, a kind of high-pressure vacuum breaker that carries operating power comprises housing 1; Said housing 1 upper end is provided with inlet wire binding post 2 and outlet binding post 3; Described housing 1 outside is provided with control box 4, is provided with the motor that drives circuit combined floodgate or separating brake in the said control box 4, is provided with voltage transformer 5 in the said housing 1; Said inlet wire binding post 2 and be electrically connected with voltage transformer 5, said voltage transformer 5 is electrically connected with motor and for it power supply is provided.According to such scheme; Be employed in voltage transformer is installed in the vacuum circuit-breaker, to operating mechanism the purpose of automatic power is provided, thereby realizes self-powered effect; Need not to install in addition power supply facilities; Simple to operate, make that the use effect of this circuit breaker is effectively improved, and voltage transformer also plays the effect of transformation.
In the utility model, shown in figure, also comprise control cabinet 6, be provided with the controller that is electrically connected through connector 7 with control box 4 in the said control cabinet 6, said connector 7 is cable or plug connector, said voltage transformer 5 is electrically connected with controller.Said controller is a relay protector, receives signal through controller and realizes the operating mechanism in the control operation case 4, rotates and drives the combined floodgate energy storage and the action of separating brake when breaking down through driving motor.Realize protection controlled function and communication function, controller and control box 4 are electrically connected through control cable and aviation connector, realize its protection and automatic monitoring function.This vacuum circuit-breaker is 10kV overhead distribution user adaptable across town and country.Controller can be with communication interface, or through optical fiber, wireless realization remote monitor; Reclosing post acceleration function: when switch coincides with permanent fault, quicken tripping operation automatically.Controller is the relaying protection and the supervising device of microcomputer type; Controller has the protection characteristics that weatherability is strong, anti-freezing is revealed; Be connected with control box through the aviation connector, connection reliability is good, degree of protection is high.
Embodiment should not be regarded as the restriction to utility model, but any improvement of doing based on the spirit of the utility model, all should be within the protection range of the utility model.
