Description
Technical field
The utility model relates to a kind of technical field of power system device, the single-phase operating breaker of specifically a kind of 145kV branch mailbox combined electrical apparatus.
Background technology
Circuit breaker is a kind of on-load switch; when the electric current in the circuit reaches the specified switching value of circuit breaker; the state of circuit breaker transfers automatic disconnection to by connection; when particularly breaking down, can match, rapidly the disengagement failure electric current with protective device and automatics in system; the accident that prevents enlarges; the protection power consumption equipment safety, guarantee system safety operation, therefore in electric power system, be widely used.In the last few years, combined electrical apparatus production and use at home, the international market forms scale gradually; The part electric power system requires the single-phase operation of circuit breaker of 145kV branch mailbox combined electrical apparatus; The circuit breaker of present 145kV branch mailbox combined electrical apparatus is generally the three-phase combined operation, i.e. three operating mechanisms that match; This kind structure three operating mechanism that matches adopts mechanical linkage, can't realize the single-phase operation of circuit breaker.
Summary of the invention
The purpose of this utility model provides a kind of rational in infrastructure, the circuit breaker of stable performance, simple and reliable, the 145kV branch mailbox combined electrical apparatus that can realize the single-phase operation of circuit breaker.
The technical solution adopted in the utility model is: the single-phase operating breaker of a kind of 145kV branch mailbox combined electrical apparatus, comprise operating mechanism, mechanism case, arc control device and transmission device, in the circuit breaker three-phase below of each phase all the transmission device by separately be connected with operating mechanism independently respectively, described transmission device comprises transmission case, vertical pull bar and outer connecting lever, be provided with interior connecting lever in the described transmission case, interior connecting lever one end is connected with the arc control device insulated tension pole, the other end is connected by the outer connecting lever of splined shaft with the transmission case outside, outer connecting lever is articulated and connected by vertical pull bar and operating mechanism, described three operating mechanisms all are connected with electrical interlock, and three operating mechanisms are fixed in the mechanism case by link plate.
Described transmission case is arranged on the arc control device below by crossbeam, and described mechanism case is fixed on the underframe of branch mailbox combined electrical apparatus by support.
The three-phase of circuit breaker of the present utility model adopts three operating mechanisms, and three-phase is respectively by independent input drive system control, and promptly each all has a cover transmission device, operating mechanism mutually, realizes the single-phase independent breaking-closing operating of circuit breaker.The utility model promptly can be realized the single-phase operation of circuit breaker, also can realize the three-phase combined operation by electrical interlock.
Description of drawings
Fig. 1 is a schematic diagram of the present utility model
Embodiment
Now in conjunction with the accompanying drawings the utility model is further described, Fig. 1 is a kind of embodiment of the present utility model, comprise operating mechanism 5, support 4, mechanism case 2, crossbeam 9, arc control device 10 and transmission device etc., in the circuit breaker three-phase below of each phase all the transmission device by separately be connected with operating mechanism 5 independently respectively, described transmission device comprises transmission case 7, vertical pull bar 6, outer connecting lever 8, described transmission case 7 is arranged on the arc control device below by crossbeam 9, be provided with interior connecting lever in the transmission case 7, interior connecting lever one end is connected with arc control device 10 insulated tension poles, the other end is connected by the outer connecting lever 8 of splined shaft with transmission case 7 outsides, outer connecting lever 8 is articulated and connected with operating mechanism 5 by vertical pull bar 6, described three operating mechanisms 5 all are connected with electrical interlock, and three operating mechanisms 5 are fixed in the mechanism case 2 by link plate 1.Described mechanism case 2 is fixed on the underframe 3 of branch mailbox combined electrical apparatus by support 4.
When certain phase operating mechanism 5 of operation, operating mechanism 5 output shafts are by vertical pull bar 6 and outer connecting lever 8, connecting lever moves up and down in driving, the insulated tension pole that connecting lever drives corresponding certain phase arc control device 10 inside is simultaneously done upper and lower motion, thereby realizes that every phase arc control device 10 moving cells finish cut-offfing, closing and close action of circuit breaker separately; Also can operate three-phase operating mechanism 5 simultaneously, thereby realize that three synchronised finish cut-offfing, closing and close action of circuit breaker by electrical interlock.
This shows, the utlity model has rational in infrastructure, stable performance, simple and reliable, can be real The characteristics such as the existing single-phase operation of 145kV branch mailbox combined electrical apparatus breaker.
