Description
Technical field
The utility model relates to a kind of technical field of power system device, specifically a kind of 252kV potting breaker that cut-offs the 63kA short circuit current.
Background technology
Circuit breaker is a kind of on-load switch, and when the electric current in the circuit reached the specified switching value of circuit breaker, the state of circuit breaker transferred 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 recent years, China's electric power system continues to big electrical network, big unit, superhigh pressure, big capacity direction fast development; The part electric power system has required the 252kV potting breaker to cut-off the 63kA short circuit current; The present domestic 252kV potting breaker that can cut-off the 63kA short circuit current that do not have as yet.
Summary of the invention
It is reasonable that the purpose of the utility model provides a kind of compact conformation, stable performance, reliable, the 252kV potting breaker that can realize cut-offfing the 63kA short circuit current.
The technical scheme of novel employing is; A kind of 252kV potting breaker that cut-offs the 63kA short circuit current comprises support, arc control device, tank body, current transformer, transmission case and mechanism case, and tank body is horizontally installed on support top; Arc control device are arranged on tank interior; The both sides on tank body top are provided with current transformer, and the top of current transformer is provided with sleeve pipe, and sleeve pipe passes current transformer inside and is connected with arc control device; Side at tank body is provided with transmission case; The arranged outside mechanism case of transmission case is provided with operating mechanism in the mechanism case, operating mechanism is connected
through the transmission mechanism in the transmission case with arc control device.
Operating mechanism in the said mechanism case is a hydraulic pressure spring operating mechanism, and this hydraulic pressure spring operating mechanism is for being horizontally disposed with, and hydraulic pressure spring operating mechanism is connected with arc control device through the iron pull bar in the mechanism case.
Described arc control device are connected with sleeve pipe through the plug-in type contact.
Described current transformer is built-in current transformer.
The utility model arc control device be fixed in the tank body and be horizontally installed on the support, transmission case and mechanism case are arranged on tank body one side, the formation translation seal, this device layout compact conformation has improved transmission efficiency; The utility model also is horizontally disposed with the operating mechanism of mechanism case; Directly be connected through the iron pull bar in the transmission case with circuit breaker; Promptly directly drive arc control device and do left and right motion; Thereby realize that every phase arc control device moving cell accomplishes cut-offfing, closing and close action of circuit breaker separately, reduced transmission link, make transmission efficiency higher.
Description of drawings
Fig. 1 is the sketch map of the utility model.
Embodiment
Combine accompanying drawing that the utility model is further described at present; Fig. 1 is a kind of embodiment of the utility model; Comprise support 5, arc control device 4, tank body 3, current transformer 2, transmission case 9 and mechanism case 8 etc., tank body 3 is horizontally installed on support 5 tops, and arc control device 4 are arranged on tank body 3 inside; The both sides on tank body 3 tops are provided with current transformer 2, and current transformer 2 is built-in current transformer 2.The top of current transformer 2 is provided with sleeve pipe 1, and sleeve pipe 1 passes current transformer 2 inside and is connected with arc control device 4, and the arc control device 4 in the present embodiment are connected with sleeve pipe 1 through the plug-in type contact.Side at tank body 3 is provided with transmission case 9, and the arranged outside mechanism case 8 of transmission case 9 is provided with operating mechanism 7 in the mechanism case 8, and operating mechanism 7 is connected
through the transmission mechanism in the transmission case 9 with arc control device 4.Operating mechanism 7 in the present embodiment in the mechanism case 8 is a hydraulic pressure spring operating mechanism, and this hydraulic pressure spring operating mechanism is for being horizontally disposed with, and hydraulic pressure spring operating mechanism directly is connected with arc control device 4 through the iron pull bar in the mechanism case 8.
Since the utility model arc control device 4 be fixed in the tank body 3 and be horizontally installed on the support 5; Transmission case 9 is arranged on tank body 3 one sides with mechanism case 8; Form translation seal,, make a whole set of switchgear structure compact more simultaneously again because of carrying current transformer 2; Layout is more reasonable, has improved transmission efficiency.The utility model also is horizontally disposed with the operating mechanism 7 of mechanism case 8; Iron pull bar through in the transmission case 9 directly is connected with circuit breaker; When operation during certain phase hydraulic pressure spring operating mechanism, these operating mechanism 7 output shafts directly drive arc control device 4 through the iron pull bars in the transmission case 9 and do left and right motion, thereby realize that every phase arc control device 4 moving cells accomplish cut-offfing, closing and close action of circuit breaker separately; Reduced transmission link, made transmission efficiency higher.The utility model can also be operated the three-phase operating mechanism simultaneously through electrical interlock, thereby realizes cut-offfing, closing and close action of three synchronised completion circuit breaker.
The utility model can be realized cut-offfing the 63kA short circuit current, and it is reasonable to have a compact conformation, stable performance, characteristics such as reliable.
